Hello Martin,

Thanks your answer, but these settings were already set in my sun-web.xml Here is my sun-web.xml:

You can call the webservice at: http://67.192.86.35/add/services/MediaService/getVideosByGenreIds?genresIds=239&maxResults=10&recursive=true

and the other one (which is also cached): http://67.192.86.35/add/services/MediaService/getTracksByGenreIds?genresIds=22032&maxResults=10&recursive=true

You can see if you call these two services again the second one's response time is much faster than the first one. The caching works well in case of getTracksByGenresIds and I dont know why?
