Indeed. If it is within the same context this is trivial - look into singleton design pattern.
It's a bad idea to use singletons in a web application, especially when the application needs to be reloaded (this is one of the causes that make lots of people write about an OutOfMemoryException!). Samuli, I think that you should try portlets to achieve inter-portlet communication. Servlets are not designed to communicate each other! Or maybe this is a false problem and you can solve your problems by better design your business logic.
