Implement JSR-107

Rate this Message:
Hi Everyone,
I am currently investigating which cache library to use for our project. JCS looks promising, but so does EHCache. I think in order to stay competitive with EHCache it would be good to implement net.sf.jsr107cache As far as I can tell at the moment JCS looks technically more promising then EHCache, but I feel a little worried about the lack of activity on the project for at least the last half year and there has not been a major release for a long time. Regards, Pierre |

Hi Aaron,
two questions from that basically. 1) Do you have plans to implement JSR-107? (At the moment everyone seems to use net.sf.jsr107cache, like EHCache, Google AppEngine) 2) Its been long since version 1.3 has been released. What is does the roadmap look like for version 1.4?

This is probably a bug with the admin jsp. Can you programtically call getStats and log the result.
Also, do you see any other errors in the logs.
