Parsing Failure in config.xml: java.lang.IllegalArgumentException

A few days back I encountered the following error and WebLogic failed to start with BEA-00362 Critical Error

Are you also having the same error?

Solution

This happens when MW_HOME is not defined and weblogic.jar is getting called twice in CLASSPATH.

To fix this, check below two points.

MW_HOME=/your/path/wls1036/

Start Oracle WebLogic now, it should work!
