Java LinkageError when deployed to weblogic

Question

I am working on a large application and I just added a new web service created by eclipse using the axis. The application works fine in my development environment (where the application is located on the pier), but now I am having problems running my application in weblogic (where the application needs to be deployed). The error I am getting is:

java.lang.LinkageError: loader constraint violation in interface
itable initialization: when resolving method
"org.apache.axis.client.Service.getServiceName()Ljavax/xml/namespace/QName;"
the class loader (instance of
weblogic/utils/classloaders/ChangeAwareClassLoader) of the current
class, org/apache/axis/client/Service, and the class loader (instance
of sun/misc/Launcher$AppClassLoader) for interface
javax/xml/rpc/Service have different Class objects for the type
getServiceName used in the signature

This problem has delayed development for several days. As I understand from the search on the Internet:

• The My Axis dependency contains the class: org.apache.axis.client.Service, which follows the javax.xml.rpc.Service interface.
• My Weblogic provided an interface: javax.xml.rpc.Service
• Since they are in a different path (application and weblogic), they are loaded by different class loaders.

1st question: Are my observations correct?
