WebLogic Classpath does not append the classpath options under server start

When I add some new directories, jars etc to the WebLogic classpath under Server Start, it somehow does not append these values to the existing classpath. It just replaces the existing classpath with what I have provided in ClassPath under Server Start.

To get around this problem, I need to put the existing classpath under Server start and then add the additional classpath 开发者_StackOverflowdirectories.

Is there a way to tell WebLogic to consider the values specified under ClassPath to be treated as additions to the already existing classpath?
