The lack of a response might indicate that there's no such option. Just kicking the can myself, I can't think of one that would tell WebSphere Application Servers to remove a running
Java class file from memory, and replace it with a new one, without bouncing the application itself first.
In IRAD7.x, we just republish, but that usually causes the WebSphere
test server environment to stop and start.
I'm happy to be proven wrong on this point though.
