    Socket Timeout with EJB2 on JBoss v4.0.5GA?

    klester Mar 11, 2009 4:52 PM

      JBoss 5 seems to support timing out sockets if an EJB method takes too long. This is done via adding a "timeout" parameter to the the connector configuration in the ejb3.deployer/META-INF/jboss-service.xml.

      Is there an equivalent to this with EJB2? We have noticed that our clients sometimes hang while calling a remote EJB method, and we would like to add a timeout so that the clients will give up after a set amount of time. I have modified my jboss-bean.deployer/META-INF/jboss-service.xml file to include a connector that times out similar to the EJB3 version, but it does not work.

      My modified jboss-service.xml is below:

      <?xml version="1.0" encoding="UTF-8"?>

<server>

 <!--

 <mbean code="org.jboss.kernel.deployment.jboss.JBossBeanDeployer"

 <attribute name="Extension">.beans</attribute>
 <attribute name="MetaDataURL">META-INF/jboss-beans.xml</attribute>
 </mbean>

 <mbean code="org.jboss.remoting.transport.Connector"

 <attribute name="Configuration">
 <handlers>
 <handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
 </handlers>
 </attribute>
 </mbean>

</server>


      Is it even possible to time out remote ejb calls in EJB2 the same as can be done with EJB3? If so, does anyone see what I am missing/doing wrong?

      Thanks in advance

          My previous post may have been a little confusing, so a quick clarification:

          We are using JBoss 4.0.5GA. Using EJB3 with JBoss 4.0.5GA, you can indeed time out long ejb method calls using the connector as described in my previous post. We would like to implement the same timeout mechanism for our EJB2 application running on JBoss 4.0.5GA.

          Does anyone see what is wrong with my previously posted connector or know of a different way to accomplish this?

            Hi klester,

            I have the same issue here. Did you find out the solution?

            Thanks!

              Sure did [sorry for the late response]. I posted a similar question in the JBoss Remoting Forum, and someone pointed me toward using the JBoss Unified Invoker to accomplish this. The thread in the JBoss Remoting Forum is http://www.jboss.org/index.html?module=bb&op=viewtopic&t=152317.

              At a high level, the Sun RMI timeout parameters don't work for the communication between the clients and the server because they don't use the Sun RMI libraries for their communication; they use the JBoss Remoting libraries. So in order to get the timeouts to work, you have to configure the JBoss Remoting libraries.

              To do so, you have to define the UnifiedInvoker in the jboss-service.xml and set the timeouts for it. You do that in the following file:
              - <jboss_home>/server/<app_name>/conf/jboss-service.xml

              Next you have to tell JBoss that your remote EJBs should use the configured UnifiedInvoker for their communication. You do this in the following file:
              - <jboss_home>/server/<app_name>/conf/standardjboss.xml

              I basically followed the instructions in the following document:
              http://docs.jboss.org/jbossas/unified_invoker/UnifiedInvoker_guide.html

              For reference, the steps I followed and the resulting configuration changes are below:

              First I added the UnifiedInvoker configuration to my jboss-service.xml. The full configuration is below. The "timeout" attribute is the one that actually times out the sockets:

              <!-- Changes to Support the Unified Invoker:

              I added the following to my standardjboss.xml file which defines an EJB invoker that should use the UnifiedInvoker previously configured in the jboss-service.xml: 
               <!-- A configuration for Stateless Session beans that tells then to use the unified invoker rather than the rmi one.

 this configuration in the "Standard Stateless SessionBean" configuration below.

              That's it. I did some testing and it worked properly. We put this change into production 2 months ago (over 1000 clients attached to our server), and we haven't seen any issues so far, so I'm fairly confident that it works as expected.

                Hello klester,

                I am newbie at jboss forums and am trying to use your guide to configure the timeout in my Jboss server.

                I've modified jboss-service.xml including the Mbeans UnifiedInvoker and Connector; I've applied changes too in the standardjboss.xml adding the invoker-proxy-binding and replacing in the container "Standard Stateless SessionBean" to use the new proxy invoker.

                I've coded a sample HelloWorld Stateless Bean; when I try to deploy the service, Jboss shows me the error:

                I am using Jboss 4.0.3Sp1 and Jdk 1.4


                I've tried with Jboss 4.0.5GA too and got same error.


                It could be a EJB conf problem?

                Thank you very much in advance.

                  Hello,

                  Just fixed, I have to add the the invoker to start before the scanner starts looking at /deploy.


                  But anyway I am unable to make the EJB Client gets a timeout.

                  I'll reply with more details later.

                  Regards
