I want to integrate Oracle JDK with IBM WebSphere Application Server instead of the default IBM JDK. If possible, how can I configure WebSphere to use the Oracle JDK?
Not supported. You must be using Java that ships with WebSphere Application Server. Oracle Java is only supported for the WebSphere Liberty profile. However, since WAS 8.5.5 you can use IBM Java SDK 6 or IBM Java SDK 7.
