I need clarification. My current application is using jdk 1.2.4. However we plan to migrate to jdk 1.6. It is posible if we dont want to migrate weblogic 8.1 to weblogic 10 . do weblogic 8.1 compatible with jdk 1.6. As i know weblogic 8.1 comes with bundle 1.4.2. is there any patch need to be done?
