Resolve weblogic.descriptor.BeanAlreadyExistsException: Bean already exists: exception

Sometimes while deploying the adf application, we get the following error. 

weblogic.descriptor.BeanAlreadyExistsException: Bean already exists: "weblogic.j2ee.descriptor.wl.LibraryRefBeanImpl@87de1187(/LibraryRefs[[CompoundKey: adf.oracle.domain]])"

This can be because of some configuration corruptions in the weblogic-application.xml file














Open the weblogic-application.xml and remove any duplicate library references if at all present.




Now try to deploy the application, it should work.
