To develop Java EE web application using standard Eclipse Java IDE has many limitations, to overcome those limitations the Eclipse project has already created "Java EE Developers". Below are the steps to demonstrate, Building and Deployment of Web Application on JBoss Application server using "Java EE Developer".
Steps:
1) Download and Install "Eclipse IDE for Java EE Developers"
http://www.eclipse.org/downloads/?osType=win32
2) Create new project by selecting "Dynamic Web Project"
[File][New][Project...][Web]
3) Set Project name : AirlineTicketReservation
(Keep other values to default)
4) Add reference to the external Servlet library so that we can use Servlet API in our application
[jboss-5.0.1.GA/common/lib/servlet-api.jar]
/AirlineTicketReservation/WebContent/WEB-INF/web.xml
/AirlineTicketReservation/WebContent/searchView.html
/AirlineTicketReservation/src/controller/SearchController.java
/AirlineTicketReservation/WebContent/image/airline.png
6) Build the project
7) Export as a WAR (Web Archive) file : AirlineTicketReservation.war
8) Deploy the WAR file to application server (Such as JBoss)
9) Access web application using URL with the web application context AirlineTicketReservation
10) Confirm log information
11) Source reference:
i) /AirlineTicketReservation/WebContent/WEB-INF/web.xml
