How to create a simple distributed Map for Java application?

I am looking for a Map to share information between two instances of a Java web application running on separate machines. Reads and writes to this map need to be very fast and don't have to be transactional i.e. its ok if one instance has stale data for a while.

Any recommendations?

I need to keep track of the last time a user did something in the application, so its not terribly bad if this information is out of date. Speed and ease of use are important. I don't want writes to the Map to impact response times.

Additionally, there is Memcached which is very robust and proven over the time.

I would try Hazelcast, JGroups or Ehcache. All support a distributed map.

EDIT: Another option is to use RMI top a service running in one or the other JVM. This avoids the need for an additional library.
