Sharing data between servlets

["Lars Preben S. Arnesen" <l....@usit.uio.no>]

I have a few servlets that needs to share some data. For initial
testing I used the Resin servlet engine, but now I'm switching to
Tomcat.

When running the servlets on Resin, I fetched a pointer to the "root
context" like this:

ServletContext context = getServletContext().getContext("/");

When using Tomcat, the context pointer always is set to null.

So, is this the "correct" way to share data between servlets, or is
there a more elegant way that works on different servlet engines.

Code snippets to illustrate how the best way to share data between
servlets are appreciated. :)
