jeez : 1000 ? the issue may come from the fact that the portal creates a transaction when it insert the objects (in order to ensure atomicity among other things), too many objects could lead to have a processing time larget than the transaction timeout value, leading to an automatic rollback of the transaction. you could try and increase the default value of the transaction timeout : 1/ edit the file server/default/conf/jboss-service.xml 2/ locate the mbean jboss:service=TransactionManager 3/ increase the attribute TransactionTimeout from 300 to a larger value View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4007506#...
