I'm able to deploy the mbean if i use lib\jboss as the base directory.... I wasn't able to access it from my code, because i could not control the order of the depencies jars for the ear file. What i realy need is a large cache for POJOs. i'll need to presist it to the DB (for fast startup). In the future i would like to have a limited sized memory cache, with ability to load fast the POJOs from DB (2nd level cache). 1. I'm i right on choosing PojoCahce? 2. How do i deploy a PojoCache as Mbean in jboss-4.0.3SP1? 2.1 do i have to use older jboss-cache.jar or should jbosscache.jar is enough? 2.2 what is the mbean "code" class needed to be used?
