Re: [JBoss-dev] [ jboss-Bugs-562004 ] 'Error setting column value' using dependent value classes with existing db records
hey List, Since there hasn't been any feedback on this bug yet, I would like to start taking a look at it myself, as it is important for the project I'm working on. I would appreciate any extra developer documentation (UML diagrams would be super) that might be out there that would help me get up to speed quickly on (for starters) the JBossCMP portion of the codebase. I looked on the developer page of the website, but noticed that the developer guide page ( http://main.jboss.org/developers/guide/ ) is empty. I already have a working cvs HEAD, so I'm really just looking for codebase docs. Thanks justin Bugs item #562004, was opened at 2002-05-29 14:11 You can respond by visiting: http://sourceforge.net/tracker/?func=detailatid=376685aid=562004group_id =22866 Category: JBossCMP Group: CVS HEAD Status: Open Resolution: None Priority: 5 Submitted By: Justin Casp (jcasp) Assigned to: Nobody/Anonymous (nobody) Summary: 'Error setting column value' using dependent value classes with existing db records Initial Comment: I posted this problem a few weeks ago on jboss.org forums, but it's down right now so I can't reference that post. I figured out how to create a simple test case that reliably reproduces the problem. The error message 'Error setting column value' occurs when I have an existing CMP bean that reads existing records from a datasource. The bean uses a dependent value class, although I'm not sure if this problem is specific to dependent value classes or just any cmp bean with fields mapped to columns. If I create the record externally (e.g., using psql, the postgres command line tool) and only set a few of the columns to non-null values, when I attempt to load that bean instance with a finder, jboss throws the following exception on the server: 12:03:56,650 ERROR [STDERR] java.lang.NullPointerException 12:03:56,652 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 12:03:56,652 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:3 9) 12:03:56,653 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImp l.java:25) 12:03:56,653 ERROR [STDERR] at java.lang.reflect.Method.invoke(Method.java:324) 12:03:56,653 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCTypeComplexProperty.setColumnValue(JDBCT ypeComplexProperty.java:142) 12:03:56,654 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCTypeComplex.setColumnValue(JDBCTypeCompl ex.java:158) 12:03:56,654 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCTypeComplex.setColumnValue(JDBCTypeCompl ex.java:133) 12:03:56,654 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCAbstractCMPFieldBridge.loadArgume ntResults(JDBCAbstractCMPFieldBridge.java:352) 12:03:56,655 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCAbstractCMPFieldBridge.loadInstan ceResults(JDBCAbstractCMPFieldBridge.java:304) 12:03:56,655 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCLoadEntityCommand.execute(JDBCLoadEntity Command.java:140) 12:03:56,655 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCLoadEntityCommand.execute(JDBCLoadEntity Command.java:62) 12:03:56,655 ERROR [STDERR] at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.loadEntity(JDBCStoreManager .java:496) 12:03:56,656 ERROR [STDERR] at org.jboss.ejb.plugins.CMPPersistenceManager.loadEntity(CMPPersistenceManage r.java:410) 12:03:56,656 ERROR [STDERR] at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.loadEntity (CachedConnectionInterceptor.java:314) 12:03:56,656 ERROR [STDERR] at org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invoke(EntitySynchro nizationInterceptor.java:310) 12:03:56,657 ERROR [STDERR] at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(Cac hedConnectionInterceptor.java:147) 12:03:56,657 ERROR [STDERR] at org.jboss.ejb.plugins.EntityInstanceInterceptor.invoke(EntityInstanceInterc eptor.java:193) 12:03:56,657 ERROR [STDERR] at org.jboss.ejb.plugins.EntityLockInterceptor.invoke(EntityLockInterceptor.ja va:107) 12:03:56,658 ERROR [STDERR] at org.jboss.ejb.plugins.EntityCreationInterceptor.invoke(EntityCreationInterc eptor.java:69) 12:03:56,658 ERROR [STDERR] at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxIntercepto r.java:96) 12:03:56,658 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT .java:167) 12:03:56,659 ERROR [STDERR] at org.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:61) 12:03:56,659 ERROR [STDERR] at org.jboss.ejb.plugins.SecurityInterceptor.invoke(SecurityInterceptor.java:1 29) 12:03:56,659 ERROR [STDERR] at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:166) 12:03:56,659 ERROR [STDERR] at
