Problem with a query
I have a problem with a query that includes a relation between to entities beans EjbCollection and Type. I was not sure how to do it but I tried the following:
<query-method>
<method-name>findAlle</method-name>
<method-params/>
</query-method>
<jboss-ql><![CDATA[
SELECT OBJECT(ejbcollection)
FROM
EjbCollection AS ejbcollection,
IN(ejbcollection.Type) type
]]></jboss-ql>
The error message:
org.jboss.deployment.DeploymentException: Error compiling JBossQL statement 'SELECT OBJECT(ejbCollec
tion)
FROM
EjbCollection AS ejbCollection,
IN(ejbcollection.Type) type'; - nested throwable: (org.jboss.ejb.plugins.cmp.
ejbql.ParseException: Encountered "ejbcollection.Type" at line 4, column 40.
Was expecting:
<COLLECTION_VALUED_PATH> ...

If I remove the ‘IN(ejbcollection.Type) type’ then the program deploys fine.
Can anyone see what is wrong? Or maybe ref. to an example I can study.
