    javaripper


      Hello,
      I'm trying to instantiate TreeCacheMBean inside a MDB.
      all works fine but

      SOMETIMES
      console writes
      the following error : (is a configuration problem???).
      Put down error an configuration service xml ::

            Can you use another CacheLoader, e.g. BdbjeCacheLoader (you don't need a license unless you ship your app).
            This is probably a bug in FileCacheLoader, I'll have a look shortly.

              Can you remove all data and retry ? Maybe you have data written with an older version of FileCacheLoader ?

                Bela

                I am using the same version of FileCacheLoader write/read.

                Versions i'm using:
                jboss-4.0.0RC1
                jboss-cache Version 1.01 April, 2004

                Thank you in advance.

                  Can you turn this into a unit test (or just some *simple* sample code) that reproduces the problem ? I looked at the code, and it looked fine: simple serialization/deserialization of a hashmap.
