      Hi, when I use Jboss in my application, I get the above error. I unjar the file under org/jboss/tm/jboss.tar downloaded from jboss.org. TransactionTimeoutConfiguration.class does not exist.

      Anybody has some idea? Thanks.

          Which version of JBoss? How do you start JBoss? And post the entire exception stacktrace.

                What is this DbConn class? Is it a standalone java class? What is it trying to do? It look strange, since it calls the

                Is this the exact exception stacktrace or did you remove some parts out of it? Can you post the code where this is being done? And the JBoss jars that you have placed in the classpath, where did you pcik these jars from?

                  Hello all

                  I am ver sorry to post this here, but i have been completely unable to find any help on this topic on the jboss website

                  I am receiving posts about Installation, Configuration & DEPLOYMENT by e-mail, and I want to stop receiving them, but i cannot find the way to do so. Any help will be highly appreciated.

                  Best regards to all, and, again, all my apologies.

                    jazzinto,

                    The right place to ask this question would be at http://www.jboss.com/index.html?module=bb&op=viewforum&f=216.

                    When you login to the forum, you will see a "Watched Forums" link, where you can configure the forums you want to watch. Have you selected "Installation, Configuration & Deployment" forum there? If yes, then unselect it. That should stop any mails being sent out when someone posts in this forum.

                    If this does not work or if you have any other questions related to this, please open a new topic in http://www.jboss.com/index.html?module=bb&op=viewforum&f=216.

                      Somebody helped me solve the problem. What was missing is jboss-transaction.jar. Thank you all for help.
