weblogic.utils.compiler.ToolFailureException Weblogic 12.2.1

Question

When deploying my application to Weblogic 12.2.1, I get this error:

weblogic.application.ModuleException:
weblogic.utils.compiler.ToolFailureException: Neither prefer-application-packages  
nor prefer-application-resources can be specified when prefer-web-inf-classes  
is turned on in weblogic.xml

In weblogic.xml , I have set prefer-web-inf-classes to true.

I use JDeveloper to deploy the application. Nowhere in my application's deployment descriptors ( web.xml and weblogic-application.xml ) do I use prefer-application-packages or prefer-application-resources . Why is Weblogic showing this error?

Regards, Jeroen

Answer 1

Check carefully, based on the documentation over here: Deployment Descriptor Elements , A value specified in the Administration Console will take precedence over a value set manually. So it must have been set somewhere.

Answer 2

If you have prefer-web-inf-classes to true so you can't use prefer-application-packages. You have to use one of them but not both....

I had the same issue migrating from WL11 to WL12 :

Weblogic 12c : Prefer-web-inf-classes and prefer-application-packages for Jersey

After all :

1. Use just prefer-web-inf-classes to true.
2. If you use this, you don't need to use prefer-application-packages ....BUT ENSURE that you have the correct libraries at war /ear level.

Answer 3

can you export your application to an ear file and there verify if there is no weblogic-application.xml with prefer-application-packages or prefer-application-resources tags ?

Jdeveloper creates automatically those files when there are any shared libraries, and could be the case.
