Hi,
I am working on migrating a WebLogic(5.1.0) app to JBoss 4.0.5GA.
Here my concern is that there are finders specified in the weblogic-cmp-rdbms-jar.xml which need to be migrated.

My questions are:
1. I understand that for every <finder> in weblogic-cmp-rdbms-jar.xml, there should be a corresponding <query> in the ejb-jar.xml, but i could not find one such in this application. There are no query elements in ejb-jar.xml

2. Can I specify an expression (?3 IS NULL) in JB QL corresponding to (isNull $3) in WL QL

3. Can I write only EJB QL in ejb-jar.xml, instead of writing JBQL in jbosscmp-jdbc.xml because the latter might cause dependency issues later as WLQL cause now?

4. Is there any help available in the net which specifies in detail about JBQL?

Please Help!
