Can you take a screenshot of the following things and PM them to me (by clicking the PM button under my name and sending them as attachments):
1) When weblogic is running, a screenshot of the debug perspective. Please use Window > Reset Perspective before taking the screenshot.
2) A screenshot of the Java editor you have open and a class file you have set a breakpoint on that isn’t enabled.
3) A screenshot of your WebLogic 8.1 connector configuration screen (just the first page).
And also please post the result of MyEclipse > Installation Summary > Installation Details for me.
