Re: Persistent space question

It looks like the problem is that the digest in the codebase annotation for the
persisted entries no longer matches because the contents of TraceService-dl.jar
have changed.  A way to get around this problem might be to package the newly
compiled classes in a different jar file and use that new jar file in the
codebase annotation henceforth, while still making the previous jar file
(TraceService-dl.jar) available for persisted entries.

Hope this helps,

Juan
