    Prasoon Agarwal Newbie

      Hi,
      I am new to jboss.please help me for the following problem.
      In my application i have a .ini file where we have some configuration values which must be set at the time of deployment of the build.
      What i am trying to do is creating a MBEAN through which we can change the values through jmx console. and my application will read all the values from this mbean.
      i have created one interface and one class which implements the interface.
      when i try to compile the build it says build suceesful and i also can see the sar file in the server>default>deploy folder.
      but imedidately after i am getting this exception.
