-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 "Different contexts" isn't necessarily the same as "different JVMs". I think that tomcat uses a single JVM instance for all of the webapps. They just use different classloaders to keep things from "accidentally" interfering with one another. This might be as simple as explicitly loading the common class through the system classloader.

I have never used the XML-RPC service either. I thought about using RMI. Both approaches seem to much overhead for the problem. The reason I need have access to common objects in memory is consistency of cached data. Both application access some common files and a common database on the server they are running on. To improve performance I tried to keep more data in RAM. It works fine in each of the two applications (one is for intranet and the other for internet access), however they won't get updates from one another anymore. Accessing the same objects would not only solve the problem efficiently, it would also help me save some RAM. I am currently considering the option of merging them into one application, but I'd rather not. There really should be a way to have a reference to the same object. The 2 webapps are running in the same JVM after all, aren't they?
