Summary: DeploymentException and invalid EJB-QL statements
Initial Comment:
It seems JBoss gets mixed up when deploying an entity
bean with an invalid EJB-QL statement. The
DeploymentException is always reported for the last
entity bean declared in the ejb-jar.xml .
Please have a look at the attached testcase. Although
the invalid query belongs to the 'Test1' bean, JBoss
shows another bean in the list of incomplete
deployments:
18:04:32,634 ERROR [URLDeploymentScanner]
Incomplete Deployment listing:

Here is another problem I found with EJBQLParser
2004-07-09 14:34:58,937 DEBUG
[org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLQuery.AccountEnabledStatus#findByAccount]
EJB-QL: SELECT OBJECT(o)
FROM AccountEnabledStatus o
WHERE o.accountid=?1
2004-07-09 14:34:59,812 INFO [STDOUT]
org.jboss.ejb.plugins.cmp.ejbql.ParseException: FROM not found
2004-07-09 14:34:59,812 INFO [STDOUT] at
org.jboss.ejb.plugins.cmp.ejbql.EJBQLParser.parse(EJBQLParser.java:39)
You don't see the problem here but in deploymnet descriptor
FROM is on a new line and as result parser recives ejbql
string that contains /n before FROM.
Becouse the check that throws this exception actually looks
for " from " it can't find it. I fixed this by adding
.replaceAll("/n", " ");
at line 36 so it is now
String lowerCase = ejbql.toLowerCase().replaceAll("\n", " ");

Right. That's because CMP engine is started after all the
EntityPersistenceManager's are created. Then it compiles
queries, resolves relationships, etc. If something goes
wrong the last started EJB container which provoked the
start of CMP engine will be reported as guilty. The message
reports what query is wrong and why though. So, I don't
consider it as a critical bug.
