    jboss as 7 slsb timeout for a request

    Ramesh Chokkapu Newbie

      Hi Good Evening..!!

       

      We have recently migrated to Jboss 4 to jboss 7.

       

      We will get  lakhs of requests to my jboss server.

      we are processing each request  max response time below 2 seconds.

      but some of request are taking long time, means more than 5 minutes.

      we want to exit from these long time requests.

      please help me.

      which timeout is better.

      1) EJB  or  2) Http .

       

      How to configure timeout for  EJB ????

      How to configure timeout for  Http ????

          For EJB's you might set the invocation.timeout property which is millis, the invocation will interrupted with a java.util.concurrent.TimeoutException.

          But remember that only the invocation is interrupted, the server side will continue. You might need to ensure with a Tx timeout that the transaction does not commit.

            Thank you for Reply..

             

            we are not using  Apache  front-end .

             

            Please kindly suggest me, Its become as urgent.

             

            We are using stateless session beans.

            where should i configure in standalone.xml.

            how i can go through with Annotations.

             

             

            We are not using any ejb-client.

             

             

            My clients will post request to servlet,  From that servlet, we will call ejb method.

            we are using ejb3.

             

             

            Servelt :

             

             

            public class MySerlvet extends HttpServlet {

                @EJB

                MyEJBBean myEJBBean;

              protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {

                      String RS = myEJBBean.processEjbMethod(rqstring);

              }

            }

             

             

            EJB :

             

             

            @Stateless

            @LocalBean

            @TransactionManagement(javax.ejb.TransactionManagementType.BEAN)

            public class MyEJBBean {

                 public String processEjbMethod(String rqstring) {

                            --------------------

                           -----------------------

                       return rs;

                  }

            }

             

             

            Please kindly suggest me..

              There is no timeout at server side for this, neither standalone.xml nor annotation.

              The only way to control it is the ejb-client side where you can set the timeout property as I explained.

               

              If you use the eib invocation local, i.e. from JSF you can not set a timeout for the ejb.

              A possible solution might be a @Asynchronous EJB invocation
