NoClassDefFoundError when deploying EAR

Solution: Fix your EAR package structure:

Wrong	Right

Further information:

1. All projects/ files have been created with Eclipse
2. application.ear: Exported as “Enterprise Application Project”
3. app-ejb.jar: Exported as “Enterprise Java Beans Project”
4. app-web.war: Exported as “Dynamic Web Project”
5. app-shared.jar: Exported as “Java Project”, that contains classes that are used by more than one of the sub-projects. Can also be a third party jar-File with library classes.
6. Exception occurs, since app-web.war or app-ejb.jar may be deployed just before app-shared.jar has been deployed. A workaround for that would be to first deploy app-shared.jar separately and remove it from your enterprise application compilation.
