Share Objects at application level on clustered environment

Dear Experts,

This might be old question, but I could not find the right solution. I have web application and deploying on WebSphere Community edition (WAS CE) server on 4 different machines for load balancing purpose.  I want to store some constant variables/objects among the four servers. I mean if I change the variable in web application on one server, same copy should be available for the web apps on other 3 servers. Since these variables/objects are not related to user session, so sticky-session will not help here. Whether JNDI is the best solution? kindly share your knowledge on any other better solutions/techniques.

Thanks in advance.

Depending on your exact requirements you could go down a number of different routes to get a solution.

Maybe something fairly simple like, serializing those variables/objects to either a filesysytem file (and having that file located on a shared drive, for example) or to a database, and then have the code on the 4 servers periodically check for updated values and reload.

Otherwise, you might need to look into a "distributed cache" type of solution. There are a number of different vendors for such a solution, such as...

http://ehcache.org/
http://www.hazelcast.com/
http://commons.apache.org/proper/commons-jcs/
...and many others

I can't really say more than just providing those suggestions, as that would require a lot more detail on your actual requirements, but start with looking into those (or others) and if you have further questions, post back here.
