I have JBoss v4.0.3SP1 installed along with MySQL v5.0.22. I am using Eclipse 3.1.2 with MyEclipse 4.1.1 for my development. I am using XDoclet to generate the code for the EJBs.
In my application I have my CMP EJBs configured for v2.X. In one of my EJBs I have the following finder: | * @ejb.finder | * query="SELECT OBJECT(t) FROM TaxMaster t WHERE t.taxNbr >= ?1 ORDER BY t.taxNbr" | * signature="java.util.Collection findListByTaxNbr(java.lang.String partialKey)" | * description="find the list of entries that start with a specific character string" | When I run this the DAOImp module fails with | javax.servlet.ServletException: Unexpected Error | java.lang.OutOfMemoryError: Java heap space | ; CausedByException is: | Unexpected Error | java.lang.OutOfMemoryError: Java heap space | | Obviously JBoss is trying to read every entry in the table that satisfies the query and load it into memory. This won't work at all. According to the JBoss documentation I can include a LIMIT parm on the QL call. So I changed the QL to: | * @ejb.finder | * query="SELECT OBJECT(t) FROM TaxMaster t WHERE t.taxNbr >= ?1 ORDER BY t.taxNbr ASC LIMIT ?2" | * signature="java.util.Collection findListByTaxNbr(java.lang.String partialKey, int tLimit)" | * description="find the list of entries that start with a specific character string" | Now when I attempt to deploy the application I get the following failure: | 10:56:42,111 INFO [BaseLocalProxyFactory] Bound EJB LocalHome 'TaxMaster' to jndi 'TaxMasterLocal' | 10:56:43,736 INFO [STDOUT] org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "LIMIT" at line 1, column 79. | Was expecting one of: | <EOF> | "," ... | So, how do I implement the LIMIT option? I don't mind to upgrade to a more current version if that will fix the problem. But I'd rather not go to that touble just yet if it won't help. I have researched this somewhat and can't find anything in the forums that indicate that JBoss has a problem with LIMIT. So I am hoping I am just doing something wrong. Thanks for your interest and feedback.
