How to run WebLogic 8 in MyEclipse?

I was trying to start WebLogic 8.1 from MyEclipse, but it failed with the following errors. The WebLogic 8.1 installation was working fine when started with the script "startWebLogic.cmd". The problem seems to be caused by the version (1.5) of JVM MyEclipse uses to run the WebLogic. How to solve this problem?
