Hello, I am trying to run an example about transactions using timeout ... and i was surprised when i ran the code ... Using another transaction manager, like jotm, bitronix, the time-out from a user transaction do the following timeout := X seconds ut start action 1 action 2 action 3 ut commit if error ... ut rollback if action1 or action 2 o action 3 are into the period of X seconds , they will not executed ... for example ... if action 1 got a lot of time, more than timeout, then, action 2 and action 3 never been executed ... right ... But, using jboss-user transaction, ... the time-out exception is throwed when action 3 finished !!!! ... the following sample shows my problem .. package paq; import java.io.IOException; import java.io.PrintWriter; import java.util.Date; import javax.annotation.Resource; import javax.ejb.ApplicationException; import javax.persistence.EntityManager; import javax.persistence.EntityManagerFactory; import javax.persistence.EntityTransaction; import javax.persistence.PersistenceContext; import javax.persistence.PersistenceUnit; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.transaction.UserTransaction; public class Tiempo extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { private static final long serialVersionUID = 8150995692542819134L; @Resource private UserTransaction ut; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); try { out.write("<br>" + new Date()); ut.setTransactionTimeout(1); ut.begin(); Thread.sleep(3000); out.write("<br>" + new Date()); out.write("->1" + ut + "<br>"); Thread.sleep(3000); out.write("<br>" + new Date()); out.write("->2" + ut + "<br>"); Thread.sleep(3000); out.write("<br>" + new Date()); ut.commit(); } catch (Exception e) { out.write("<br>" + new Date()); out.write("<br>Excepcion:=" + e); } } } The exception from time-out is throwed after 9 seconds !!!! nooo ... i need it al least at 2 seconds !! and never run the hole of transaction ... why do i need to run a completed tx when the first is broken into a timeout !!! if my transaction has 3 operations and a timeout is 4 hours , 1.- spends 1 hour, 2.- spends 1 hours , 3.- spends 2 hours ... if i got a problem and the first one and second need 4 hours to finish, i don't want to wait another 2 hours to recieve the time-out exception !!! how can i resolve it thank you _______________________________________________ jbossts-dev mailing list jbossts-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jbossts-dev
