I supose that the problem using the getUserTransaction is that if the transaction is already running, and I use that, may appears a concurrency problem. But using always a new transaction, could give me problems of performance? </SPAN><BR /><BR /><SPAN>I'm implementing a java backed webscript. A lot of users will use my service, and for each one the code will use 4 o 5 transactions. What's the better option? When is the best option use getNonPropagatingUserTransaction vs getUserTransaction?</SPAN><BR /><BR /><SPAN>Thanks!</SPAN><BR /><BR /></BODY></HTML> Mon, 26 May 2014 08:30:23 GMT spilby 2014-05-26T08:30:23Z getUserTransaction vs getNonPropagatingUserTransaction https://connect.hyland.com/t5/alfresco-archive/getusertransaction-vs-getnonpropagatingusertransaction/m-p/303061#M256191 The non-propagating (REQUIRES_NEW) ensures that the transaction is always new.
