    Conversation timeout in Seam3

    Louis Engelbrecht Newbie

      Hi.


      I have some questions regarding conversation timeouts in Seam3 and hope that someone can answer it,


      1. Where can I see what the current default/global timeout is for conversation in the current Seam 3?


      2. Where and how can I set the default/global timeout?


      3. What is a good timeout for conversations? Should conversations have a shorter timeout than sessions and how much shorter?


      Thank you.

          I believe that's specified either in the CDI spec or in the CDI implementation.



          2. Where and how can I set the default/global timeout?


          I don't recall, but you can manually change the timeout per conversation when you promote it to a long running conversation.



          3. What is a good timeout for conversations? Should conversations have a shorter timeout than sessions and how much shorter?


          Yes, shorter than a session, it has to be shorter or the same as a session as conversations are sections of a session. How much shorter really depends on your application. There is no general rule.

            Does anyone know if the functionality mention in http://seamframework.org/Seam3/FacesModule to globally set the conversation timeout is implemented yet.


            In http://seamframework.org/Seam3/FacesModule it states:



             <beans xmlns="http://java.sun.com/xml/ns/javaee"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns:s="urn:java:seam:core" 
               xsi:schemaLocation="
                  http://java.sun.com/xml/ns/javaee 
                  http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
               
               <s:Conversation>
                  <s:specializes/>
                  <s:timeout>5000</s:timeout>
               </s:Conversation>
               
            </beans>






            Is the timeout value in milliseconds?

              Yes, it's milliseconds.

                But that doesn't work (java.lang.Exception: Could not resolve node Conversation in namespace urn:java:seam:core)

                 

                I've tried :

                <?xml version="1.0" encoding="UTF-8"?>
                <beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                          xmlns:s="urn:java:ee"
                          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://jboss.org/schema/cdi/beans_1_0.xsd">
                          <s:Conversation>
                                    <s:Specializes/>
                                    <s:timeout>2000</s:timeout>
                          </s:Conversation>
                </beans>
                

                 

                 

                And there is seems there are no problem, but actually, my conversations still don't last 2 seconds, but much more. So it is not taken into account.

                  This is at a spec level (the conversation timeout). I suspect the best you'll be able to is manually set the conversation timeout when you begin, or as I said earlier, looking into how each implementation does it.
