[i dont think this exception is coming for me because of transaction being marked as rollback or timed out transaction, if thats the case log would have contained some info regarding that.] waiting for your reply, thank you.... -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/783042#783042] Start a new discussion in IronJacamar Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
