[jboss-user] [EJB 3.0] - LEFT OUTER JOIN problem

[zengchuan]

I use jboss4.0.4RC1.
Code:
sql = "SELECT  c.id ,c.centerId ,c.centerName ,c.centerFullName ,c.address1 ,c.address2 ,c.zipCode ,c.tel1 ,c.tel2 ,c.fax ,c.homepage ,c.parentCenterId ,c.remark ,d.centerName FROM M_Center c  LEFT OUTER JOIN M_Center d  ON c.parentCenterId = d.centerId  ORDER BY c.levelDesc ";
List data = manager.createQuery(sql).getResultList();

Then problem happend:

12:14:18,296 ERROR [PARSER] line 1:228: unexpected token: ON
12:14:18,312 ERROR [[ZCZ0001Action]] Servlet.service() for servlet ZCZ0001Action threw exception

	at org.jboss.ejb3.tx.Ejb3TxPolicy.handleInCallerTx(Ejb3TxPolicy.java:89)
...
How can I do for the sql?
