    How can I solve NoClassDefFoundError

    metalhamster Newbie

      Hi everyone,

       

       

      Before I tell you what my problem is, I think it's better to briefly explain how my project is structured.

       

      My project has the following structure:

        myproject

         \_ myproject-application

         \_ myproject-common

             \_ ch/myproject/common/errors/RestError.java

         \_ myproject-web

             \_ ch/myproject/web/rest/Resource.java

         \_ myproject-test

             \_ ch/myproject/test/arquillian/rest/ResourceIntTest.java

       

      myproject-application will build an ear with the war of myproject-web inside it. And myproject-web has a reference to RestError of myproject-common.

      For the testing I generate a test.jar that I add to the ear file and then deploy the ear file. So far so good.

       

      But now I want to test if the response contains the expected error when I request an inexisting resource on my REST API.

      However, if I try to parse the response body to my class RestError I'll get a NoClassDefFoundError.

       

      As I have understood, this means that the class is found during build time but later it is not found anymore.

       

      What do I do wrong?
