[jira] Commented: (AMQ-2659) JMSException incorrectly thrown when using XAConnection/XASession outside a transaction

    [ https://issues.apache.org/activemq/browse/AMQ-2659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=58986#action_58986 ] 

Gary Tully commented on AMQ-2659:
---------------------------------

what is your use case here? it is normal for an xa connection to be used with an xa transaction, that is what xa_rdonly is about. Not sure why the check was added in the first place but it has been around for quite a while and is a good indication of intent, as in, it helps determine whether an XA connection factory is being used as desired when it is configured with a transaction manager. I am slow to drop it without out good reason.

> Currently, if one attempts to use an XAConnection (implemented by ActiveMQXAConnection) and consequently an XASession (implemented by ActiveMQXASession) outside a transaction, a JMSException is thrown.  However, nowhere in the JMS Spec does it say that if an XAConnection/XASession is used, it _*must*_ be enlisted in a transaction.  It is perfectly legal to _*not*_ start a transaction but still use the XA objects.
> I propose that the following 2 methods in ActiveMQXASession be changed as follows to resolve this bug:
> {noformat}
>     public boolean getTransacted() throws JMSException {
>         return getTransactionContext().isInXATransaction();
>     }
>     /**
>      * This is called before transacted work is done by the session.
>      * XA transactions are controlled outside of the session so
>      * nothing has to be done here.  The only reason for this method
>      * to be here is to override the parent.
>      */
>     protected void doStartTransaction() {
>     }
> {noformat}
> \\
> The current version of these methods is as follows (for reference):
> {noformat}
>     public boolean getTransacted() throws JMSException {
>         return true;
>     }
>     /**
>      * This is called before transacted work is done by
>      * the session.  XA Work can only be done when this
>      * XA resource is associated with an Xid.
>      *
>      * @throws JMSException not associated with an Xid
>      */
>     protected void doStartTransaction() throws JMSException {
>         if (!getTransactionContext().isInXATransaction()) {
>             throw new JMSException("Session's XAResource has not been enlisted in a distributed transaction.");
>         }
>     }
> {noformat}
