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 Arvind,

From what I understand from your requirements, you require a free (Open source)caching service to be used in your webapp with constraint of using only a web container.
Heres a good cache service - http://www.opensymphony.com/oscache/ . I have seen this being used in a very huge J2EE financial project, so you can safely use it.

Cheers
