Cause:
WAS includes Apache Wink in its JRE, which will conflict with the one in your application.
Resolving the problem:
changing WAS classloaders to PARENT_LAST. Load all of the jars that you packaged within the application before WAS tries to load the jars contained in the its JRE.
- step 1. go to the web console of WAS
Websphere enterprise Applications ->your application->Class loading and update detection
- step 2: change class loader order:
- step 3: restart the application
