Question

I have an ear which currently works fine when deployed in JBoss 4.2.3. I am attempting to migrate to JBoss 5.0.1 but am getting the error ‘classpath module listed in application.xml is not a recognized deployment’.

Below is the struture of my ear:

              MyApp
                |       
                +- classpath
                |       
                +- lib
                |   |
                |   +- A.jar
                |   +- B.jar
                |   +- C.jar
                |
                +- META-INF 
                |   |
                |   +- application.xml
                |   +- jboss-app.xml
                |
                +- D.jar
                |
                *- E.jar
                |
                +- F.jar
                |
                +- myApp.war
                    |
                    +- WEB-INF
                    |
                    +- ....

Below is what I have in my application.xml:

<application>
  <display-name>MyApp</display-name>
  <module>
    <java>classpath</java>
  </module>
  <module>
    <java>lib/A.jar</java>
  </module>
  <module>
    <java>lib/B.jar</java>
  </module>
  <module>
    <java>D.jar</java>
  </module>

  ...      

  <module>
    <web>
      <web-uri>myApp.war</web-uri>
      <context-root>/WEB-INF</context-root>
    </web>
  </module>
</application>

As mentioned the current structure of my ear and the application.xml outlined above, all works fine in JBoss 4.2.3. However, when I deploy this is JBoss 5.1.0 it appears not to like the ‘classpath’ module defined in the application.xml.

Below is the full stack trace occuring:

I’m tearing my hair out with this one! Any help would be greatly appreciated.

Thanks

The good news is that JBoss 5.x automatically adds any JARs in lib to the EAR’s classpath, so you don’t actually need to specify them in the application.xml.

For your classpath directory, you’ll have to rename that to classpath.jar, and then 5.x should accept it.
