Hi, Yes, I had tracked it down to this code segment yesterday, but wasn't sure how to proceed.
thanks, Bonnie MacKellar -----Original Message----- From: Mark Rowell To: 'OJB Users List' Sent: 10/23/03 5:23 AM Subject: RE: problems with batch-mode=true Hi Regarding this issue it looks like (at least as far as RC4 is concerned) that in the doExecute method of PreparedStatementInvocationHandler.java the following line (223) gets invoked ((Method) _methods.get(i)).invoke(stmt, (Object[]) _params.get(i)); In my case when using batched mode, and JSQLConnect on MSSqlServer I get a similar error to Bonnie (java.lang.IllegalArgumentException: object is not an instance of declaring class) The methods returned by _methods.get(i) is public void org.apache.ojb.broker.platforms.PlatformDefaultImpl.addBatch(java.sql.Pr epar edStatement) And we are trying to executed it on the statement rather than passing the platform instance. I think the problem Is in the if statement in that it does an == rather than a .equals() call to determine whether we want to call the addBatch method. Now, I do not know whether within a single JVM that the following Returns true Method method1 = obj.getClass().getMethod("methodName", <args>); Method method2 = obj.getClass().getMethod("methodName", <args>); method1 == method2; // is this gurantee dto be true like it is for instances of Class e.g. Obj.getClass() == Obj.getClass() is guranteed to be true?

You can see that setBatchMode is called before I start the tx. try { broker.serviceConnectionManager().setBatchMode(true); broker.beginTransaction(); for (int i = 0; i < 100; i++) { CustomerInterface customer = new Customer(); customer.setCustomerNumber("100" + i); customer.setFirstName("Big"); customer.setLastName("Customer"); customer.setCustomerName("BadCorporation"); customer.setDeleteTag(Boolean.FALSE); broker.store(customer); } // conMan.executeBatch(); broker.commitTransaction(); } catch(Exception e) { e.printStackTrace(); logger.error(e.getMessage()); broker.abortTransaction(); } finally { broker.close(); } This chunk of code, exectued with batch-mode="true" in repository_database.xml, results in the following two exceptions : java.lang.IllegalArgumentException: object is not an instance of declaring class at java.lang.reflect.Method.invoke(Native Method) at org.apache.ojb.broker.util.batch.PreparedStatementInvocationHandler.doEx ecut e(Unknown Source) at org.apache.ojb.broker.util.batch.PreparedStatementInvocationHandler.invo ke(U nknown Source) at $Proxy0.doExecute(Unknown Source) at org.apache.ojb.broker.util.batch.BatchConnection.executeBatch(Unknown Source) at org.apache.ojb.broker.util.batch.BatchConnection.commit(Unknown Source) at org.apache.ojb.broker.accesslayer.ConnectionManagerImpl.localCommit(Unkn own Source) at org.apache.ojb.broker.core.PersistenceBrokerImpl.commitTransaction(Unkno wn Source) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.commitTransaction (Unk nown Source) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.commitTransaction (Unk nown Source) at com.mobius.activebill.dbmigrationutils.CustomerMigration.main(CustomerMi grat ion.java:69) 3425 ERROR [main] dbmigrationutils.CustomerMigration - object is not an instance of declaring class 3435 DEBUG [main] core.PersistenceBrokerImpl - PB.close was called: [EMAIL PROTECTED] org.apache.ojb.broker.TransactionNotInProgressException: ConnectionManager is NOT in transaction at org.apache.ojb.broker.core.PersistenceBrokerImpl.abortTransaction(Unknow n Source) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.abortTransaction( Unkn own Source) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.abortTransaction( Unkn own Source) at com.mobius.activebill.dbmigrationutils.CustomerMigration.main(CustomerMi grat ion.java:75) Exception in thread "main" It looks like the persistence broker is being closed down before the call to abortTransaction is made. But that does not explain the first exception. This code works perfectly with batch-mode="false". And, if I call executeBatch, I don't get the second exception (the one about not being in a transaction), although I still get the first transaction. I am including my repository_database.xml as an attachment. It is always possible that I am doing something terribly wrong there.
