rajan.deepu.java,
Can you answer few queries for me –
1. Copy and paste your installation details here. You can get it from MyEclipse > Installation Summary > Installation Detail.
2. Can you attach a screenshot of your weblogic server connector? (Use [Post Reply] button instead of Quick reply option or use [Preview] instead of [Submit])
3. Can you document the exact steps on how you got this error?
4. What is the JDK version configured? Have you used default JDK provided by Weblogic? Can you attach a screenshot here?
5. Go to your log file. you can find the same under [your workspace dir]/.metadata/.log and copy and paste the relevant portion of the error here.
