I wanted to implement a caching system in my application to improve the performance.
My current resources to be cached are:
1. Database (master tables, frequently used query results).
2. Mappings from xml file.
3. Data from txt files.

Limitations:
1.Should be using only tomcat web container, no app server.
2.Cluster level updation of the cache.
3.The cacheable resources may be updated from different application.
4.Looking for open source.

If a system is not supporting clustering, how can I achieve it on myself?
please suggest me, the one which is more likely suitable for my usage?

thanks in advance.

Hi Aravind,

Take a look at Coherence, it meets all of your requirements except for being open source.
