      Hi,
      I'm using Jboss4.0 with mySQL 4.0
      My ejb-jar.xml contains EJB-QL like this :

      <ejb-ql>
      <![CDATA[select object(a) from ProductBean as a where basePrice < ?1]]>
      </ejb-ql>

      Whan I deploy my jar which contains above xml then Jboss server throws excpetion like this:
      2005-02-07 14:36:43,369 DEBUG [org.jboss.util.NestedThrowable] org.jboss.util.NestedThrowable.parentTraceEnabled=true

      It seems something is wrong while specifying "<" opearator. I'm afraid JBoss treats "<" operator as XML tag of Starting item!!

      Pls. help. Thx in advance!
