I will give it a try. Can you explicitly confirm that it shouldn't be a multithreading problem where there are serveral entitymanagers created in different JTA transactions running in parallel? e.g. TX A starts EM A created A working TX B starts EM B created A and B working (this is where we currently get the errors) ... > > Also, are you closing your EMs at the end of the transaction? not really. the problem is that we have serveral methods calling each other - each of it creating its own EM at the beginning. (which will be the same EM instance regarding to the lookup code we implementend - see previous mail). So close() of a sub-method would call the "outer" methods EM too I guess? Hans
