Hi
You need to post more details about your JMS and TX setup.
Which TX manager are you using? Do you use XA or not.
And the JMS broker I assume its AMQ but if not what is it?
BTW: The xpath thingy should be faster in 2.1 as we have removed a
hotspot which let it perform much better under concurrent load.
