I would need to implement a common memory area that all instances of a certain
stateless EJB could access - in fact a simple hashtable that contains general data -
and of course with access synchronization.
If I use only one JVM I can use a Singleton class containing a Hashtable - but I need
to be able to deploy our app on clusters.
A few years ago our server was a Java program with socket connections, and implementing
a common memory area (with access synchronization) was extremely simple.
What we've done was to use a simple RMI call to a java program running outside the
beans container (our app has to be able to run on JBoss but also on other containers) -
this is the method prescribed by Floyd Marinescu for implementing TRUE singletons on
J2EE with clustering - but it's a little slow for what we need, and it's an inelegant
Are there other options? Could JBoss Cache help me with this? From what I've read it
seems it is more than a Hashtable for strings (what we need) - and couldn't find any
example for using JBoss Cache for strings.
Any help would be highly appreciately.
