INTRODUCTION
PROJECT OVERVIEW
The revolutionary trends of computerization have reached the peaks achieving global goals in all fields and sectors. The IRecruit systems getting computerized are leading to a new and innovative way to approach to above said. With the major organizations hosting services of HRMS our project and implimentation specifically aims to the total computerization of the IRecruit.

With the total automation of IRecruit, the manual dependency is minimized to a large extent. It inherits all the properties of computerizing a system which includes quick response, less processing time, non-diligence, fast recovery, robustness, flexibility, reliability, scalability.
Todayâ„¢s trend demands high rate of automation for the IRecruit as the organizations are growing in exponential form and maintaining employment records in a consistent format. To satisfy the needs of clients, todayâ„¢s organization need more and more of workforce. The IRecruit system takes care of this by taking in resumes from new aspirants and allowing the HR to view them in and do selections there upon.
PROJECT SCOPE
The project and implimentation mainly focuses on recording information related to managing information related to JobPostings, People, Companies, Resumes and Candidates. Retrieving information like Job details, Resumes details, candidate details etc,.generating reports like Use Reports, Job Reports, Transaction Reports, Usage Reports, and Skill Reports. For Candidate there is a creation of new login, searching for a new job, etc. The system also enables the HR personnel to view the resumes of new aspirants and select them based on the selection criteria.
SCREEN DESIGN / GRAPHICAL USER INTERFACE
The system uses a very user-friendly interface developed using Hyper Text Markup Language (HTML), which most users are acquainted with and is broadly used on the world wide web(WWW). The controls are placed on the forms in an easily accessible manner so that user strain is minimized to the maximum extent.
Whenever a user enters any form the system also states the action to be performed in an easily understandable and pleasant speech. The navigation of the user form one area of the system to another is very easy using easy to access and properly placed hyperlinks which user can access on the click of a button.
The system also poses a unique format for each type of users; this ensures that user is presented with options he has access to. This ensures a great deal of security to the system and to the organization as an employee is not given an option to carryout unauthorized activity.
General Description
The system has Four major modules:
¢ Candidate module
¢ Employee module
¢ Recruiter module
¢ Administrator module
The welcome form of the Candidate module displays the options to a person. It has options for him to post his/her resume, searching the job, and manage Candidate. Or he/she can sing-up new account. The sign-in form is the entry point of an candidate to the site through he/she has to login everyday. When we select Candidate link in form it displays the information about the candidate. From this page candidate can manage candidate information and can post resumes.
From the search job option candidate can search the jobs posted using several criteriaâ„¢s like search words, function, location, time span.
The Employee Welcome page have the following links home, Job Postings, Resumes, People, Companies, other. Through this employee of the company nothing but the recruiter or Hr manager can see the resumes of the different candidates, can create new job etc.
The Administrator page have the following links like home, Job Postings, Resumes, People, Companies, other. With this he can manage all the details about the companies, people, JobPostings etc.

SYSTEM ANALYSIS
Need of the system
Present day organizations, especially large companies house employees in large numbers they need number of employees. In order to recruit employees they consult consultants or recruiters, so that the recruiters get the applications and scan resumes and send relevant applications to the final hr that need employees. The burden on recruiters department is immense. The lack of consistency in record maintenance leads to both loss of property as well as employee confidence.
With the total automation of IRECUIT, the manual dependency is minimized to a large extent. It should inherit all the properties of computerizing a system, which includes quick response, less processing time, non-diligence, fast recovery, robustness, flexibility, reliability, scalability¦
In addition to these characteristics the system should maintain data in consistent format all the while.
Proposed System
The proposed system should have the above features. The features of the system are, it maintains the employee details, candidate details, resume details, company details and Job Posting of companies. The system should also be easy to access, accurate and consistent results can be obtained.
The employee details include all the personal information, login information. The system should be able to maintain the details about the applicants and company details. After that, they scan resumes and forward relevant profiles to the required recruit managers. The system should also provide a new aspirant to be able to submit his/her resume and it should also take care of intimating HR about it.
FEASIBILITY STUDY REPORT
After analyzing the existing system, the organization is in need of automation of existing manual system. The organization has the capacity to stand the cost of developing new system and is willing to do that. The product will be of utmost use and the level of ease has been increased to a great extent.

SYSTEM DEVELOPMENT ENVIRONMENT
Java coding standards
Why Coding Standards are Important
Coding standards for Java are important because they lead to greater consistency within your code and the code of your teammates. Greater consistency leads to code that is easier to understand, which in turn means it is easier to develop and to maintain. This reduces the overall cost of the applications that you create. You have to remember that your Java code will exist for a long time, long after you have moved on to other project and implimentations. An important goal during development is to ensure that you can transition your work to another developer, or to another team of developers, so that they can continue to maintain and enhance your work without having to invest an unreasonable effort to understand your code. Code that is difficult to understand runs the risk of being scrapped and rewritten “ I wouldn™t be proud of the fact that my code needed to be rewritten, would you If everyone is doing their own thing then it makes it very difficult to share code between developers, raising the cost of development and maintenance. Inexperienced developers, and cowboys who do not know any better, will often fight having to follow standards. They claim they can code faster if they do it their own way. Pure hogwash. They might be able to get code out the door faster, but I doubt it. Cowboy programmers get hung up during testing when several difficult-to-find bugs crop up, and when their code needs to be enhanced it often leads to a major rewrite by them because they™re the only ones who understand their code. Is this the way that you want to operate I certainly do not.
The Prime Directive
No standard is perfect and no standard is applicable to all situations: sometimes you find yourself in a situation where one or more standards do not apply. This leads me to introduce what I consider to be the prime directive of standards:
When you go against a standard, document it : All standards, except for this one, can be broken. If you do so, you must document why you broke the standard, the potential implications of breaking the standard, and any conditions that may/must occur before the standard can be applied to this situation. The bottom line is that you need to understand each standard, understand when to apply them, and just as importantly when not to apply them.
Important Instructions to maintain standards
Use full English descriptors that accurately describe the variable/field/class/¦ For example, use names like first Name, grandTotal, or CorporateCustomer. Although names like x1, y1, or fn are easy to type because they™re short, they do not provide any indication of what they represent and result in code that is difficult to understand, maintain, and enhance (Nagler, 1995; Ambler, 1998a).
Use terminology applicable to the domain. If your users refer to their clients as customers, then use the term Customer for the class, not Client. Many developers will make the mistake of creating generic terms for concepts when perfectly good terms already exist in the industry/domain.
Use mixed case to make names readable. You should use lower case letters in general, but capitalize the first letter of class names and interface names, as well as the first letter of any non-initial word (Kanerva, 1997).
Use abbreviations sparingly, but if you do so then use them intelligently: This means you should maintain a list of standard short forms (abbreviations), you should choose them wisely, and you should use them consistently. For example, if you want to use a short form for the word number, then choose one of nbr, no, or num, document which one you chose (it doesnâ„¢t really matter which one), and use only that one.
Avoid long names (< 15 characters is a good idea): Although the class name
PhysicalOrVirtualProductOrService : might seem to be a good class name at the time this name is simply too long and you should consider renaming it to something shorter, perhaps something like Offering (NPS, 1996).
Avoid names that are similar or differ only in case : For example, the variable names persistent Object and persistent Objects should not be used together, nor should anSqlDatabase and anSQLDatabase (NPS, 1996).
Avoid leading or trailing underscores : Names with leading or trailing underscores are usually reserved for system purposes, and may not be used for any user-created names except for pre-processor defines (NPS, 1996). More importantly, underscores are annoying and difficult to type so I try to avoid their use whenever possible.
Good Documentation
We will also be discussing documentation conventions, so letâ„¢s discuss some of the basics first:
Comments should add to the clarity of your code : The reason why you document your code is to make it more understandable to you, your coworkers, and to any other developer who comes after you (Nagler, 1995).
If your program isnâ„¢t worth documenting, it probably isnâ„¢t worth running (Nagler, 1995) : What can I say, Nagler hit the nail on the head with this one.
Avoid decoration, i.e. do not use banner-like comments : In the 1960s and 1970s COBOL programmers got into the habit of drawing boxes, typically with asterisks, around their internal comments (NPS, 1996). Sure, it gave them an outlet for their artistic urges, but frankly it was a major waste of time that added little value to the end product. You want to write clean code, not pretty code. Furthermore, because many of the fonts used to display and print your code are proportional, and many arenâ„¢t, you canâ„¢t line up your boxes properly anyway.
Keep comments simple. Some of the best comments I have ever seen are simple, point-form notes. You do not have to write a book, you just have to provide enough information so that others can understand your code.
Write the documentation before you write the code. The best way to document code is to write the comments before you write the code. This gives you an opportunity to think about how the code will work before you write it and will ensure that the documentation gets written. Alternatively, you should at least document your code as you write it. Because documentation makes your code easier to understand you are able to take advantage of this fact while you are developing it. The way I look at it, if you are going to invest the time writing documentation you should at least get something out of it (Ambler, 1998a).
Document why something is being done, not just what. Fundamentally, I can always look at a piece of code and figure out what it does. For example, I can look at the code in Example 1 below and figure out that a 5% discount is being given on orders of $1,000 dollars or more. Why is this being done Is there a business rule that says that large orders get a discount Is there a limited-time special on large orders or is it a permanent program Was the original programmer just being generous I do not know unless it is documented somewhere, either in the source code itself or in an external document (Ambler, 1998a).
An Overview of J2EE
The following topics describe the J2EE Platform requirements for each kind of J2EE platform element.
J2EE Application Components
The J2EE runtime environment defines four application component types that a J2EE product must support:
Application clients are Java programming language programs that are typically GUI programs that execute on a desktop computer. Application clients offer a user experience similar to that of native applications, and have access to all of the facilities of the J2EE middle tier.
Applets are GUI components that typically execute in a web browser, but can execute in a variety of other applications or devices that support the applet-programming model. Applets can be used to provide a powerful user interface for J2EE applications. Servlets, JSP pages, filters, and web event listeners typically execute in a web container and may respond to HTTP requests from web clients. Servlets, JSP pages, and filters may be used to generate HTML pages that are an application™s user interface. They may also be used to generate XML or other format data that is consumed by other application components. A special kind of servlet provides support for web services using the SOAP/HTTP protocol. Servlets, pages created with the JavaServer Pages„¢ technology, web filters, and web event listeners are referred to collectively in this specification as web components. Web applications are composed of web components and other data such as HTML pages. Web components execute in a web container. A web server includes a web container and other protocol support, security support, and so on, as required by J2EE specifications. Enterprise JavaBeans„¢ (EJB) components execute in a managed environment that supports transactions. Enterprise beans typically contain the business logic for a J2EE application. Enterprise beans may directly provide web services using the SOAP/HTTP protocol.
J2EE Server Support for Application Components:
The J2EE servers provide deployment, management, and execution support for conforming application components. Application components can be divided into three categories according to their dependence on a J2EE server:
Components that are deployed, managed, and executed on a J2EE server. These components include web components and Enterprise JavaBeans components. See the separate specifications for these components.
Components that are deployed and managed on a J2EE server, but are loaded to and executed on a client machine. These components include web resources such as HTML pages and applets embedded in HTML pages.
Components deployment and management is not completely defined by this specification. Application Clients fall into this category. Future versions of this specification may more fully define deployment and management of Application Clients.
J2EE Containers
Containers provide the runtime support for J2EE application components. Containers provide a federated view of the underlying J2EE APIs to the application components. J2EE application components never interact directly with other J2EE application components.
J2EE Servers
Underlying a J2EE container is the server of which it is a part. A J2EE Product Provider typically implements the J2EE server-side functionality using an existing transaction processing infrastructure in combination with Java 2 Platform, Standard Edition (J2SE) technology. The J2EE client functionality is typically built on J2SE technology.
Resource Adapters
A resource adapter is a system-level software component that implements network connectivity to an external resource manager. A resource adapter can extend the functionality of the J2EE platform either by implementing one of the J2EE standard service APIs (such as a JDBC„¢ driver), or by defining and implementing a resource adapter for a connector to an external application system.
Java„¢ Transaction API (JTA)
The Java Transaction API consists of two parts:
An application-level demarcation interface is used by the container and application components to demarcate transaction boundaries. An interface between the transaction manager and a resource manager used at the J2EE SPI level (in a future release).
RMI-IIOP
The RMI-IIOP subsystem is composed of APIs that allow for the use of RMI-style programming that is independent of the underlying protocol, as well as an implementation of those APIs that supports both the J2SE native RMI protocol (JRMP) and the CORBA IIOP protocol. J2EE applications can use RMI-IIOP, with IIOP protocol support, to access CORBA services that are compatible with the RMI programming restrictions (see the RMI-IIOP spec for details).
JDBC„¢ API
The JDBC API is the API for connectivity with relational database systems. The JDBC API has two parts: an application-level interface used by the application components to access a database, and a service provider interface to attach a JDBC driver to the J2EE platform. Support for the service provider interface is not required in J2EE products.
Java Connector Architecture
The Connector architecture is a J2EE SPI that allows resource adapters that support access to Enterprise Information Systems to be plugged in to any J2EE product. The Connector architecture defines a standard set of system-level contracts between a J2EE server and a resource adapter.
Security Service
The Java„¢ Authentication and Authorization Service (JAAS) enables services to authenticate and enforce access controls upon users. It implements a Java technology version of the standard Pluggable Authentication Module (PAM) framework, and extends the access control architecture of the Java 2 Platform in a compatible fashion to support user-based authorization. The Java„¢ Authorization Service Provider Contract for Containers (JACC) defines a contract between a J2EE application server and an authorization service provider, allowing custom authorization service providers to be plugged into any J2EE product.
Deployment
The Java 2 Platform, Enterprise Edition Deployment Specification defines a contract between deployment tools and J2EE products. The J2EE products provide plug-in components that run in the deployment tool and allow the deployment tool to deploy applications into the J2EE product. The deployment tool provides services used by these plug-in components.
J2EE Architecture
Web Applications and Exploded Directory Format (EDF)
Overview of Web Applications
A Web application contains an applicationâ„¢s resources, such as servlets, JavaServer Pages (JSPs), JSP tag libraries, static resources such as HTML pages and image files. A Web Application can also define links to outside resources such as Enterprise Java Beans (EJBs). Web applications deployed on WebLogic Server use a standard J2EE deployment descriptor file and Web Logic-specific deployment descriptor file to define their resources and operating attributes. JSP and HTTP servlets can access all services and APIs available in Web Logic Server. These services include EJB, database connections via Java Database Connectivity (JDBC), Java Messaging Service (JMS), XML, and more. A Web archive (WAR file) contains the files that make up a Web application (WAR file). A WAR file is deployed as a unit on one or more Web Logic Server instances. A Web archive on Web Logic Server always includes the following files: One servlet or Java Server Page (JSP), along with any helper classes. A web.xml deployment descriptor, which is a J2EE standard XML document that describes the contents of a WAR file.A weblogic.xml deployment descriptor, which is an XML document containing Web Logic Server-specific elements for Web applications. A Web archive may also include HTML or XML pages and supporting files such as image and multimedia files. The WAR file can be deployed alone or packaged in an enterprise application archive (EAR file) with other application components. If deployed alone, the archive must end with a .war extension. If deployed in an EAR file, the archive must end with an .ear extension. BEA recommends that you package and deploy your stand-alone Web applications as part of an enterprise application. This is a BEA best practice, which allows for easier application migration, additions, and changes. Also, packaging your applications as part of an enterprise application allows you to take advantage of the split development directory structure, which provides a number of benefits over the traditional single directory structure.
Note: If you are deploying a directory in exploded format (not archived), do not name the directory .ear, .jar, and so on.
Web Application Directory Structure
Web applications use a standard directory structure defined in the J2EE specification. You can deploy a Web application as a collection of files that use this directory structure, known as exploded directory format, or as an archived file called a WAR file. BEA recommends that you package and deploy your WAR file as part of an enterprise application. This is a BEA best practice, which allows for easier application migration, additions, and changes. Also, packaging your Web application as part of an enterprise application allows you to take advantage of the split development directory structure, which provides a number of benefits over the traditional single directory structure. Web application components are assembled in a directory in order to stage the WAR file for the jar command. HTML pages, JSP pages, and the non-Java class files they reference are accessed beginning in the top level of the staging directory. The WEB-INF directory contains the deployment descriptors for the Web application (web.xml) and weblogic.xml) and two subdirectories for storing compiled Java classes and library JAR files. These subdirectories are respectively named classes and lib. JSP taglibs are stored in the Web Applications Basics WEB-INF directory at the top level of the staging directory. The Java classes include servlets, helper classes and, if desired, precompiled JSP. The entire directory, once staged, is bundled into a WAR file using the jar command. The WAR file can be deployed alone or as part of an enterprise application (recommended) with other application components, including other Web applications, EJB components, and Web Logic Server components. JSP pages and HTTP servlets can access all services and APIs available in Web Logic Server. These services include EJBs, database connections through Java Database Connectivity (JDBC), Java Message Service (JMS), XML, and more.
Main Steps to Create a Web Application
The following is an example of a Web application directory structure, in which myWebApp/ is the staging directory:
Web Application Directory Structure
An Overview of JSP
The Java Server Pages„¢ Technology
Java Server Pages„¢ technology is the Java„¢ technology in the J2EE platform for building applications containing dynamic Web content such as HTML, DHTML, XHTML and XML. The Java Server Pages technology enables the authoring of Web pages that create dynamic content easily but with maximum power and flexibility.
The Java Server Pages technology provides a textual description for the creation of a response from a request. The technology builds on the following concepts:
Template Data
Substantial portions of dynamic content is actually fixed. The JSP technology allow for the natural manipulation of this data.
Addition of Dynamic Data
The JSP technology allows the addition of dynamic data to the template data in a way that is simple yet powerful.
Encapsulation of Functionality
The JSP technology provides two related mechanisms for the encapsulation of functionality: the standard Java Beans component architecture and the tag library
mechanism.
Good Tool Support
The JSP technology has features that enable the creation of good authoring tools. The result is a flexible and powerful server-side technology.
Benefits of the Java Server Pages Technology
The Java Server Pages technology offers a number of benefits:
Write Once, Run Anywhere„¢ properties
The Java Server Pages technology is platform independent, both in its dynamic Web pages, Web servers, and its underlying server components. You can author JSP pages on any platform, run them on any Web server or Web enabled application server, and access them from any Web browser.
High quality tool support
The Write Once, Run Anywhere properties of JSP allows the user to choose best-of-breed tools. Additionally, an explicit goal of the Java Server Pages design is to enable the creation of high quality portable tools.
Separation of Roles
JSP supports the separation of roles: developers write components that interact with server-side objects.
Reuse of components and tag libraries
The Java Server Pages technology emphasizes the use of reusable components such as Java Beans„¢ components, Enterprise Java Beans„¢ components and tag libraries.
Separation of dynamic and static content
The Java Server Pages technology enables the separation of static content from dynamic content that is inserted into the static template.
Support for scripting and actions
The Java Server Pages technology supports scripting elements as well as actions. Actions permit the encapsulation of useful functionality in a convenient form that can also be manipulated by tools; scripts provide a mechanism to glue together this functionality in a per-page manner.
Web access layer for N-tier enterprise application architecture(s)
The Java Server Pages technology is an integral part of the Java 2 Platform Enterprise
Edition (J2EE), which brings Java technology to enterprise computing.
An Overview of Servlets
What is a Servlet
A servlet is a web component, managed by a container that generates dynamic content. Servlets are small, platform independent Java classes compiled to an architecture neutral byte code that can be loaded dynamically into and run by a web server. Servlets interact with web clients via a request response paradigm implemented by the servlet container. This request-response model is based on the behavior of the Hypertext Transfer Protocol (HTTP).
What is a Servlet Container
The servlet container, in conjunction with a web server or application server, provides the network services over which requests and responses are set, decodes MIME based requests, and formats MIME based responses. A servlet container also contains and manages servlets through their lifecycle. A servlet container can either be built into a host web server or installed as an add-on component to a Web Server via that serverâ„¢s native extension API. Servlet Containers can also be built into or possibly installed into web-enabled Application Servers. All servlet containers must support HTTP as a protocol for requests and responses, but may also support other request / response based protocols such as HTTPS (HTTP over SSL). The minimum required version of the HTTP specification that a container must implement is HTTP/1.0. It is strongly suggested that containers implement the HTTP/1.1 specification as well.
A Servlet Container may place security restrictions on the environment that a servlet can executed In a Java 2 Platform Standard Edition 1.2 (J2SE) or Java 2 Platform Enterprise Edition 1.3 (J2EE) environment, these restrictions should be placed using the permission architecture defined by Java 2 Platform. For example, high end application servers may limit certain action, such as the creation of a Thread object, to insure that other components of the container are not negatively impacted.
