Error description

  • After creating and accessing JMS resources, they are unable to
    be viewed from the administrative console.  For example, if you
    click on resources > JMS > topic connection factories -   the
    JMS resource entries are no longer seen and the word "null" in
    red type is seen in the "messages" box at the top of the
    screen. The problem also generates the following
    NullPointerException ( NPE ) in the SystemErr.log file:
