    Clustering Issue / SEAM

    Michael Singer Newbie

      maybe someone can give me a pointer what to check to solve this issue.

      I am working with JBoss-4.0.5.GA installed with the latest JEMS-installer. I installed the EJB3-cluster profile and I am using the latest SEAM-release 1.1.1.GA.

      In my application I have several SFSBs annotated with @Clustered and after a certain amount of time the following huge stacktrace is printed.

      The class which is not found can be any of my SFSBs so it is not always the same class which is not found. The my.TestSFSBean has 3 private String members and a private static Collection where SelectItem implements Serializable.

      Any idea?

      btw. I already posted the same question in the SEAM forum..
