    Riftsaw - log to specific file

    Igor JStarter Novice



      I need to log let's say a line for every BPEL invoke of a external WS. How to do that?


      I hoped I could somehow write the log text to a variable and print it to a file, everything in BPEL ?



      But now after readings ... I saw that some users did:




      And then wrote their CustomBpelEventListeners ....


      Could somebody explain if I can log to a file just in BPEL and if not

      what are the steps for turning on BPEL logging and catching the events ?


      Thanks in advance!


      Regards, Igor!

          Hi Igor


          I don't believe it is possible to do this from the BPEL process.


          Information on the event listener mechanism can be found in the quickstarts/bpel_event_listener/readme.txt.

            Thank you very much Gary!


            I almost thought <bpel:echo> is going to work .)


            That means...

            1.  riftsaw.sar/bpel.properties

            add line: bpel.event.listeners=org.jboss.riftsaw.event.RiftSawEventListener

            2.  copy org.jboss.riftsaw.event.RiftSawEventListener from the bpel_event_listener quickstart to your project..

            3.  restart server


            I don't see any new logs... defined by the RiftSawEventListener:

            package org.jboss.riftsaw.event;

            import org.apache.ode.bpel.iapi.BpelEventListener;

            import org.apache.ode.bpel.evt.BpelEvent;

            public class RiftSawEventListener implements BpelEventListener {

                public void startup(java.util.Properties properties) {System.out.println("MYLOG - RiftSaw BPEL event listener started");}

                public void onEvent(BpelEvent bpelEvent) {System.out.println("MYLOG -- RiftSaw BPEL event: "+bpelEvent);}

                public void shutdown() {System.out.println("MYLOG -- RiftSaw BPEL event listener stopped");}



            And i don't see anything new when starting the server...  There must be something more to do ???

            Working on that... if someone has an idea, please post...


            What is more... How can i tell JBoss that he should print this event logs to a specific file and not into the server.log...

              Have you added the:


                  <process name="bpl:HelloWorld">


                      <process-events generate="all"/>


                      <provide partnerLink="helloPartnerLink">

                          <service name="intf:HelloService" port="HelloPort"/>




              'process-events' element in your deploy.xml?


              You would need to create and log to the file within your own implementation of the listener interface.

                I have it added in the my deploy.xml. It looks like:

                  <process name="alertUsers:alertUsers">



                    <process-events generate="all"/>

                    <provide partnerLink="client">

                      <service name="alertUsers:alertUsers" port="alertUsersPort"/>


                    <invoke partnerLink="TransactionLink">

                      <service name="axis2:TransactionsService" port="TransactionsServiceHttpSoap11Endpoint"/>


                    <invoke partnerLink="PerftechLink">

                      <service name="kkiss.adapters.ws.mmw.perf.si:WsKKISSAdapterService" port="WsKKISSAdapterPort"/>




                So I don't see anything here I could change...  The <retired> can't be so important ....

                Any other idea ?   btw There is no bpelContent in the event listener quickstart example...


                About the log file: I understand what you mean.  I'll do that...

                But that has nothing to do with the log4j possibility?  I thought we'll be using log4j logger....

                  I lied...  now I see a warning in the log:

                    Did you run the 'ant deploy' from within the bpel_event_listener quickstart? This places a jar in the riftsaw.sar/lib folder.


                    You could create log4j enties and then filter them out as required.

                      In my opinion it is the same file structure as in the bpel_event_listener example...


                      So, in my myprojectname/


                      -bpelContent  (with .bpel, .wsdl, deploy.xml)

                      -src (which I copied from the bpel_event_listener ... with folder structure org.jboss.riftsaw.event.RiftSawEventListener)




                      Where should I copy the src folder ?

                        Does your build.xml construct a jar with the compiled event listener and place it in the riftsaw.sar/lib?

                          Thank you Gary!  It's WORKING!


                          I really should have seen it in the build.xml, that he's doing some extra work and not just deploy...

                                  <path id="compile-classpath">

                                  <fileset dir="${org.jboss.as.home}/client" includes="*.jar" /> <!-- Required for JMS Client Code. -->

                                  <fileset dir="${riftsaw.lib.dir}" includes="*.jar" /> <!-- Required for JMS Client Code. -->


                          So, I needed to run ant deploy on the bpel_event_listener quickstart example once...  now it's "logging" events...


                          But, on one BPEL WS call i cached about 40 events... Now I have to study how to use them for some smart logs .)



                          So this is working!  

                          But I would really like to know how I could use log4j. Could you tell something more about creating the entities ... ?

                            Yes, the line <jar basedir="${build.dir}" destfile="${riftsaw.lib.dir}/${sample.jar.name}" /> generates the file Quickstart_bpel_event_listener.jar.

                              Sorry, you'll have to find the info elsewhere - but the log4j configuration is performed in $jbossas/server/default/conf/jboss-log4j.xml for the server, but you might be able to override that locally within your own module.

                                Thank you very much!  You helped me a lot ...


                                If anybody could tell something more about using log4j, please post ...
