App Migration from 4.x to 7 - Class Not Found

[herve.ferreira.ext]

I'm trying to deploy a EJB Project from a old release 4.x into the new 7.1.1.

My EJB Project called myApp.jar contains inside a lib called myLib.jar.

This work ok in the 4.x, however in the 7.1.1 I got the

Basically in the 7.1.1 the application can not find the Classes from the lib.

How to solve this problem?

After google it I found some pages that says to create a module with the myLib.jar. I tried this, but I don't know how to reference the module from a EJB project (jar file)

Thanks for the help

Hi,

how can jar contain a jar? that sounds bit wrong.

can you post output of jar tf <name-of-your-deployment>

so we can see what are you trying to deploy.

From JavaEE perspective it sounds wrong. You need to have an ear file which can contain different jar's.

BTW, to add a dependency to a module you can add "Dependencies: my.module" to the MANIFEST or use jboss-deployment-structure.xml, see here

Your "EJB" project does not seem to contain any EJBs (and there is no ejb-jar.xml file, which I'd expect to see in JBossAS 4 app). How is the rest of your application bundled?

[herve.ferreira.ext]

My Jboss4 is customized and I have EJB3.0 in it.

I have other ejbmodules that access this ejbModule via remote interfaces.

I dont have any ear in the 4.0, but yes, I can package now in a ear.
