[jboss-user] [EJB 3.0] - Entity constraint violation - rollback

Hello I'd like to create a method helper on EJB3 entity bean in order to check that a set does not violates any constraint. ex, in acccount class, i create à debit(a) method, implementing it: | public void debit(int a) | if (this.amount>a) { | setAmount(getAmount()-a) | } else { | ????? | } | if this account doesn't have enough money, I'd like to rollback the current transaction, in ejb2 I used setRollBackOnly on the context, I did not find any equivalent. The only solution I found is to throw a runtimexception (dirty solution IMO) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969068#...
