Hi,

I get the following error on trying to start Weblogic 9.

Should I add any jars in the classpath for myeclipse in the preferences section?

thanks
Vidya

Are you trying to run WL9 with a 1.4 VM? I believe java.lang.instrument package was added in Java 5. Make sure you have configured to run it with a Java 5 (1.5) JDK.
