Where to place JAR library

[anton_duca]

Hi

I have written an application using EJB 3.0.

Some EJB Session Beans use classes from a library named clase_maporama.jar.

When I invoke methods of these EJBs I get runtime errors (class not found - for classes from clase_maporama.jar).

I have put the clase_maporama.jar archive in the jboss's client, server/default/lib, and server/default/deploy but no effect.

Thanks
Tony

How is your application packaged? Is it an .ear. If yes then, place the clase_maporama.jar directly in the myApp.ear and make an entry in the application.xml(present in myApp.ear/META-INF directory) as follows:

<module>
 <java>clase_maporama.jar</java>
 </module>

However, the classes in your clase_maporama.jar should have been loaded, when you had placed this jar under %JBOSS_HOME%/server/default/lib directory.

Yes. It is an EAR. I forgot to mention I already tried the "java" tag option (which is the most elegant).

My application.xml is:

<module>
 <ejb>logitrack.ejb3</ejb>
 </module>
 <module>
 <ejb>logitrack.par</ejb>
 </module>
 <module>
 <java>clase_maporama.jar</java>
 </module>
 <module>
 <web>
 <web-uri>logitrack.war</web-uri>
 <context-root>logitrack</context-root>
 </web>
 </module>

I just dont get why is not working.

Thanks
Tony

java.lang.NoClassDefFoundError: MapoWebService_pkg/MapoWebServiceLocator

Just as i guessed, this is not a Class not found exception. This is a NoClassDefFoundError, which means that the classes referred by MapoWebService_pkg/MapoWebServiceLocator(through its import statements or extends statement or through some other means) are NOT present in the classpath. Place these classes/jars in the classpath

[anton_duca]

Ooops.

You are right.

These clase_maporama.jar was created using the AXIS wsdl
(I thought Jboss has all it needs for these - JUST TO FIND AN EXCUSE)


Thank you very much
Tony
