[JBoss-user] Does CMR Collections have to be accessed (iterated) inside a transaction?
Hello! I am developing two entity beans which have a relatinship 1-N (One User can have Many Roles). I have also a Facade session bean to handle the business operations. I have declared the Transaction property of my beans (Entity and session) as Supports. The methods which insert or update data are declared as Required. I don't want read-only operations to be executed inside transactions. I have one method (getUser) which returns a VO with the User data and calls the relation method (getRoles() which returns a Collection of Roles). As this is a read operation, I don't want a transaction to handle this method. Although I am having one exception when I try to iterate the list of roles returned by the getRoles method java.lang.IllegalStateException: A CMR collection may only be used within the transction in which it was created Does CMR collections have to be accessed inside transactions?

Re: [JBoss-user] Does CMR Collections have to be accessed (iterated) inside a transaction?
It is in the spec. It would be easy to support iterating outside of the spec, but you would get an inconsistent database on a writeable database. -dain Herve Tchepannou wrote: Is this a requirement of EJB standard or just due to JBoss implementation? -Original Message- From: julien viet [mailto:julien_viet;yahoo.fr] Sent: Tuesday, November 05, 2002 6:16 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] Does CMR Collections have to be accessed (iterated) inside a transaction? yes they have. --- Victor Batista [EMAIL PROTECTED] a écrit : Hello!
