Disclaimer: I may have jumped to conclusions in my previous posting. I based my
diagnosis on the following deployment-exception in JBoss 3.0.4:
org.jboss.deployment.DeploymentException: Error compiling ejbql; - nested throwable:
(org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "Type" at line 1, column
32.
Was expecting one of:
"IN" ...
<ABSTRACT_SCHEMA> ...
I couldn't find other occurences of "Type" in the ejb-jar.xml that looked suspicious.
However, when I manually removed the 'extra' query-occurence the same
deployment-exception pops up...
If you have ideas about what's wrong, I'd really like to hear! Anyone used
EJB-inheritance + xdoclet successfully?
