Hi,

I wonder if I should rather use JBossCache or JGroups (or maybe something 
completely different) to implement a solution for the following problem:

I my current project, we have a core server and a number of of so called 
optimization servers. Both types of servers are implemented using Spring and 
run on Tomcat each. The core server needs to send sends optimization requests 
to the optimization servers which in turn pick up their work pckage and start 
processing. (The business case is to achieve a maximum load factor on cargo 
trains). The problem is that some optimization requests may be executed in 
parallel, while others may not be executed in parallel. So we do need something 
like a global hashmap that stores a list of all optimization requests along 
with an information whether any of the optimization servers is working on this 
package.

At first, I thought it might be a good idea to use JGroups and the 
DistributedHashmap, but then I read the JavaDoc deprecation comment "Use 
JBossCache instead" :-) So, which one should I use?

Peter
