Class Loading

sammie88 Jan 31, 2013 5:04 PM

I have 2 modules being deployed in JBoss7 -

ModuleA.jar (EJBs)

ModuleB.rar (connector)

ModuleA.jar uses a class in ModuleB.rar so I put a "Dependencies: deployment.ModuleB.rar" in my Manifest.mf for ModuleA.jar

This works. The problem is ModuleB.rar uses some classes back in ModuleA.jar (like utility classes for logging, exceptions)

How do I specify the dependency back to ModuleA.jar - I have a circular/inter dependency in other words. What is a better way of packaging this?

I tried putting a "Dependencies.." on the ModuleB.rar but it failed to deploy

Thanks- any help is appreciated.

Can the common files be placed in a module which both reference?

Thanks Nicklas- I was thinking of that too - the new shared module though would just have utility classes - can I still put that jar in the deployment directory even though it is not an EJB, connector,etc ? Is that conventional? Sorry Im new to this..

It would be a module

A module in the deployment folder?

It doesn't need to be a module. Just place the classes in a jar in the EAR/lib directory and they will automatically be available to all components in the EAR.

This is bog standard JEE packaging.

...

OK, so I read your original post again. If you're not using an EAR then you should consider it. It will make life simpler for you.

{code}EAR/
   META-INF/
      application.xml
   ModuleA.jar
   ModuleB.rar
   lib/
       utilities.jar
{code}

You don't need to add stuff to manifests or anything like that.
