Learn to deploy EJBs on JBOSS

[mick allens]

Hi all

Am pretty much new to JBOSS & EJBs, would appreciate if someone could help me with some intresting pointers on developing/deploying EJBs on JBOSS.

I have installed JBOSS 4.0.3 sp1 n have started off with servlets , went well till now.

I want to deploy a complete J2EE application with EJBs as a EAR.

kindly help...

Create an .ear file, lets say myApp.ear. The contents might look like the following:

myApp.ear
 |
 |--------- META-INF
 |            |
 |            |---------- application.xml
 |
 |--------- myEJB.jar
 |            |
 |            |--------- META-INF
 |            |            |
 |            |            |-------- jboss.xml
 |            |            |
 |            |            |-------- ejb-jar.xml  
 |            |
 |            |------ org
 |            |         |----- myApp
 |            |                 |------- ejb
 |                                        |-------- *.class
 |
 |---------- myWeb.war
 |              |
 |              |----- WEB-INF
 |                      |------ web.xml
 |                      |
 |                      |------ jsp
 |                               |---- *.jsp
 |
 |---------- commonUtil.jar
               |
               |--------- org
                           |----- myApp
                                    |------ common
                                             |----- *.class                

The application.xml will contain:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN" "http://java.sun.com/dtd/application_1_3.dtd">
<application>
<display-name>helloworld</display-name>

<module>
<java>commonUtil.jar</java>
</module>
 
<module>
<web>
<web-uri>myWeb.war</web-uri>
<context-root>/myWeb</context-root>
</web>
</module>
 
<module>
<ejb>myEJB.jar</ejb>
</module>
 
</application>

Forgot to mention, you will have to place the .ear file in the %JBOSS_HOME%/server/default/deploy directory

If you just have to deploy EJBs, then there is no need for creating ear file. You can just create an jar containing the EJBs and deploy it. Have a look at this thread for more information.
