Websphere and LTW with spring-agent

I have a java-spring application.It has load-time-weaver implemented through spring-agent.jar and aspects-weaver.jar.I want to implement the same thing without giving the jvm -javaagnet argument.I read in the spring refernece manual that LTW can be switched on by a ClassLoader basis.Has anybody tried this?

Yes and it doesn't work for Websphere. You still need the spring-agent.jar. Check the reference guide for that, it is supported on a limited number of app servers.
