将应用程序从WAS 6.1迁移到WAS 8.5

Question

I am migrating applications from WAS 6.1 to WAS 8.5. Existing application works fine in WAS 6.1 but in WAS 8.5 while connecting to a bpm wsdl url, I am getting the following exception. The jar is present in WEB-INF/lib

Answer 1

Switch the class loader to local first, parent last.

In application configuration go to:

1. Class loading and update detection
2. Change class loader order to local first
3. Save changes
4. Restart application server

Answer 2

For using third party Web service engine you need to set class loader to parent last and disable annotation scanning:

Set the DisableIBMJAXWSEngine property in the META-INF/MANIFEST.MF of a WAR file or EJB module to true

See documentation for more details:
