    Transactional Replication with SimpleJTA

    Lars Huber Newbie

      On committing the UserTransaction i'm receiving an error. I've got two Treecaches in the same cluster. That means: two vm's on the same machine.. I'm using the TransactionManager "simplejta-0.84". Without transaction the replication works correctly. Also in case of one Treecache and a JDBC DataSource it works correctly. But in the case of two members in the cluster, it doesn't work.

      Implementation:
      -begin UserTransaction
      -modify Treecache
      -commit UserTransaction

      i'm receiving the error:
