> Hi,
> I have recently tried using JCS 2.0 version. my intention is to improve the performance of my application since my application communicates data base frequently. So, i have implemented a single service on cache, and when i run this service as a standalone(not through web module, but using main method in java), i am able to prove that the call is going to cache for sure for second time since the first call must go to data base. And, finally my issue is, when i deploy the same application, which has cache implementation, and run the web module, i am getting below exception. Can you please solve it as soon as possible since i am dead line. and if possible, can you share a best cache.ccf file for best config.
