Hi, As part of a debugging process, I am trying to enforce Transaction Time out. I am using Jboss-3.2.3 and have changed the following configurations. The beans are Container managed. jboss-service.xml - with "TransactionTimeout" attribute set to 45 sec. <mbean code="org.jboss.tm.TransactionManagerService" name="jboss:service=TransactionManager" xmbean-dd="resource:xmdesc/TransactionManagerService-xmbean.xml"> 45 <depends optional-attribute-name="XidFactory">jboss:service=XidFactory jboss.xml in META-INF - <ejb-name>TestSessionBean</ejb-name> <jndi-name>TestService/TestSession</jndi-name> <exception-on-rollback>true</exception-on-rollback> true <method-attributes> <method-name>testOverriddenTimeoutExpires</method-name> <transaction-timeout>5</transaction-timeout> <method-name>testOverriddenTimeoutDoesNotExpire</method-name> <transaction-timeout>5</transaction-timeout> </method-attributes> I have tried to trace the Transaction Log by appending in log4j.xml, but could not find any relevant information. I have added code to make sure that the processing would take more than a minute, but still haven't been able to simulate the transaction time out. Please let me know what else is needed to be done. Thanks for your help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4015135#...
