RE: [JBoss-user] ejb-ql problem
I don't think you can have more than one variable in the SELECT clause (per EJB 2.0 spec, section 11.2.8: 'The SELECT clause contains either a single range variable that ranges over an entity bean abstract schema type or a single valued path expression. In the case of a finder method, the SELECT clause is restricted to contain either a single range variable or a single valued path expression that evaluates to the abstract schema type of the entity bean for which the finder method is defined.').

[JBoss-user] ejb-ql problem
Hi all, I´m trying to do this with ejb-ql but I cannot get it works: 'SELECT DISTINCT a.phone_oper, a.oper_description FROM Dyt_orc_area_off_cSchema as a' when I deploy the bean it drops: 12:25:53,522 ERROR [EntityContainer] Starting failed org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT DISTINCT a.phone_oper, a.oper_description FROM Dyt_orc_area_off_cSchema as a'; - nested throwable: (org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "," at line 1, column 29. Was expecting: "FROM" ... ) at org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLQuery.(JDBCEJBQLQuery.java:46) at org.jboss.ejb.plugins.cmp.jdbc.JDBCCommandFactory.createEJBQLQuery(JDBCComma ndFactory.java:53) If I get only 1 field it works. Is there any way to do what I want?

Re: [JBoss-user] EJB-QL problem
I don't believe that JBoss parses the EJB-QL if JBossQL is present, but I would not recommend putting invalid EJB-QL in the compliant ejb-jar.xml file. You should just leave the ejb-ql element empty, which will signify to the application deployer that this query requires non-complient ejb-ql (and will need to port it). In my experience, developers just want to know what they are up against when porting an application. BTW how would your application be portable if you are using non-complient EJB-QL? -dain Patrick Golec wrote: > JBoss complains about the following finder EJB-QL query: > > SELECT DISTINCT OBJECT(o) FROM Customer o WHERE o.searchName LIKE ?1 > > I understand that JBoss doesn't accept the parameters in the LIKE > operator, so I have overridden it with the JBossQL (same query), which > is cool. > > However, I want to maintain the portability of the application, so I > would like to have both: EJB-QL in the ejb-jar.xml and JBossQL in the > jbosscmp-jdbc.xml. > > My question is: is there any way to turn off EJB-QL query parsing when > JBossQL query is present?

[JBoss-user] EJB-QL problem
JBoss complains about the following finder EJB-QL query: SELECT DISTINCT OBJECT(o) FROM Customer o WHERE o.searchName LIKE ?1 I understand that JBoss doesn't accept the parameters in the LIKE operator, so I have overridden it with the JBossQL (same query), which is cool. However, I want to maintain the portability of the application, so I would like to have both: EJB-QL in the ejb-jar.xml and JBossQL in the jbosscmp-jdbc.xml. My question is: is there any way to turn off EJB-QL query parsing when JBossQL query is present? So that the app deploys with the EJB-QL unmodified? Thanks! --- Patrick GolecSoftware ArchitectArachne Prime Inc.
[JBoss-user] EJB QL Problem
When deploying an app with the following query Jboss throws an java.lang.NullPointerException at org.jboss.ejb.plugins.cmp.jdbc.SQLUtil.getJoinClause(SQLUtil.java:311) SELECT OBJECT(p) FROM productcategory AS c, IN (c.products) AS p WHERE p.id = ?1 The relation is many to many. The nullpointer exception is being thrown somewhere around where JBoss returns the lists of pkFields and fkFields for the where clause in the SQL. I'm sure i'm doing something stupid and it's probably way past bedtime, but has anybody else run into this problem?
