User, the NoClassDefFoundError exception points to a class loader problem. Sometimes the problem is static code in a bean or it's the order of libraries loaded from your application and the server you are deploying to.

You can check https://examples.javacodegeeks.com/java-basics/exceptions/java-lang-noclassdeffounderror-how-to-solve-no-class-def-found… and https://www.youtube.com/watch?feature=player_detailpage&v=ArLTKapjV_8&app=desktop  which helps you understand the problem.

Hi Timo, thank you for fast response, and for the heads up for order of libraries.

I will watch through materials you provided and posted back.

What concerns me is that this problem occurs in the simplest kind o application as soon      Configuration.createRootApplicationModule("model.AppModuleImpl ", "AppModuleImplLocal");      is invoked (no static or anything).

If i remember correctly in 11g i had no problems with this specific use case.

I ve looked through links, and ill look more into cat. problem is that this Configuration class is from oracle.jbo.client.Configuration package on which I don't have any control. I will see what results cat give, but whatever they were I am not sure how to solve them

I am posting this link also so, you can see what I was doing

I was trying to fix my problem from yesterday but with no success although i have some additional information. I am hoping that you can point me in right direction.

I checked with ClassLoader Analysis Tool and it did not found any class conflicts.

I was researching a bit more, and found out that when I run my Web Service Class from inside JDeveloper everything works fine. It deploys application to integrated weblogic and web service is available and fully functional.

If I try to pack it inside a War and regardless of deployment method (console, enterprise manager, jdeveloper) or server (integrated, dedicated )result is always the same - deploys OK, available via ws_utc, but when some method is invoked i get ::

<oracle.dms.instrument.Noun> <Noun> <findOrCreateByPath> <Attempt to create pre-existing noun /DefaultDomain/DefaultServer/com.oracle.webservices.wls.ws-testclient-app-wls, of type wls_jaxrsapp_resources, with a conflicting type wls_ear.>

Judging by the first line, it should be the conflict, but i cant find anything inside CAT, and I would really appreciate any help regarding the issue .

On the link, i provide application example, very light, without datasoruce or anything, just 2 projects, one has app module with one method, second has ws with method to invoke method from app module.
