Problem: The library referenced on the classpath of this
project can only be accessed at run time if this project is part of an EAR
and the EAR’s weblogic-application.xml deployment descriptor references
this library.
Resolution 1: Remove the library from the project classpath. For instructions on how to do this, see Removing a library reference from the project classpath.
Resolution 2: Create a new EAR project (or use an existing one). In the EAR project’s Properties (right-click the EAR and select Properties) select the page labeled Java EE Module Dependencies. Select the project from the list, and then click Finish to associate the project with the EAR project.
