    ClassNotFound Exception after Jboss 5.1 start - after hot deployment working

    Benjamin Mark Newbie

      Hello,


      I have a strange behavior of my project.
      When I start the Jboss 5.1 Server with the seam 2.2.0 project I get the stacktrace below.
      When I rebuild and hot-deploy the same code into the server everything works fine.


      It exactly happens with my DAO object inside a quartz processor discussed in thread
      Seam Thread QuartzNotWorking.


      Do someone have the same behavior or do someone has a Idea what it could be?


      Thx in forward for your help


      Ben

            Benjamin Mark Newbie

            Found some other threads with that issue.


            Seems to be a class load problem with the quartz library.


            After putting the quartz.jar into my deployment lib it is working without any errors at server start.
