We have JBoss [EAP] 4.3.0.GA_CP01 environment and I need to modify the 

TransactionTimeout

property of

but whenever i try to change the value via MBean from JMX-Console; following stacktrace shows up:

Is there a way programmatically to change the value of TransactionTimeout without bouncing the server at the run-time??

    Thank you Nicholas!

    Here is the Java code which can be used to change the transaction timeout on runtime…

    MBeanServer mBeanServer = MBeanServerLocator.locateJBoss();
TransactionManagerDelegate tmd = (TransactionManagerDelegate) mBeanServer.getAttribute(new ObjectName("jboss:service=TransactionManager"), "TransactionManager");
System.out.println("Prev: " + tmd.getTransactionTimeout());
tmd.setTransactionTimeout(200);
System.out.println("New: " + tmd.getTransactionTimeout());

    And as you quoted,
    Note that this will not change the value reported in the MBean’s TransactionTimeout attribute however the value will be effective for all transactions post this operation.
