    7.2.0.Final and jboss-deployment-structure.xml

    Sueleyman Vurucu Expert

      Hi Guys,

       

      I try to migrate my ear app from 7.1.1.Final to 7.2.0.Final. during the deployment the drools classes are not found. This works fine 7.1.1.Final.

       

      I create a modules directory for drools libs. And refer to it from jboss-deployment-structure.xml.

       

      <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
      <!--
      <ear-subdeployments-isolated>true</ear-subdeployments-isolated>
       -->
          <deployment>
          
              <dependencies>
                  <module name="org.drools" slot="main"  />
                  <module name="org.hibernate" slot="main"   />
                  <!-- 
                   -->
                  <module name="org.infinispan" slot="main" />
                  <module name="org.jboss.as.clustering.infinispan"/>
              </dependencies>
          </deployment>
      </jboss-deployment-structure>
      

       

      I get allways a ClassNotDoundExcpetion Caused by: java.lang.ClassNotFoundException: org.drools.SystemEventListener

       

      If I register my drools module as global module then everrything works fine.

       

       

       <global-modules>
                  <module name="org.drools"/>
        </global-modules>
      

       

       

      But with this approch I have problems to configure log4j. Is  jboss-deployment-structure.xml invalid for 7.2.0.Final ??

          Hi,

           

             I tested  My Demo Drools application as with the following kind of "jboss-deployment-structure.xml"  and it is working fine at my end on "AS 7.2.0.Alpha1"

          The Test Application can be found in the following link:   https://github.com/jaysensharma/MiddlewareMagicDemos/tree/master/Drools5.3_Demo_In_JBossAS7

           

          **NOTE:  as the above link contains a WAR which has all the mentioned jars inside the "WEB-INF/lib"  so you will need to alter the attached TestCase a little bit in order to remove the Jars from the WEB-INF/lib  as these jars are now going to be loaded via Module.   Just compare it with your application to see if you are doing anything different.

           

          As you are getting " java.lang.ClassNotFoundException: org.drools.SystemEventListener"  So make sure that te following JAR is added in your drools module because the missing class is available in this jar.  knowledge-api-5.3.0.Final.jar

            Hi Jay,

             

            thanks for your contribution. I don't want have the libs in my deployment. I have many testcases which deployed with arquliian. And that save me significant time for all test cases.

             

            You talk about AS7.2.0.Alpha1/modules/. But the modules dir is in 7.2.0.Final  is under ${JBOSS_HOME}/modules/system/layers/base right ??

             

            The problem is if I use jboss-deployment-structure.xml then I get the ClassNotFoundExceeption. And I know where to locate it. But joboss don't .

             

            If I activate the module via standalone.xml in section global modules then it works.

             

            With Jboss 7.1.1.Final jboss-deployment-structure.xml works as expected.

              Hi,

               

                  I double checked that My Drools Module  is created as my previous comment.   And In the the Test Application I am not placing any JAR inside the WEB-INF/lib    and everything is working just fine for me.    Just try the following once :

               

              Drools5.3_Demo_ModuleBased_JBossAS72_Alpha.zip

               

              Deploy the application on your jboss which has the "org.drools" module as mentioned in m previous comment.  Then access thr application as following:

              http://localhost:8080/DroolsHelloWorldDemo/DroolsInvokerServlet

                Hi Jay,

                 

                I'm not at work at moment. I'll try it immediately tomorrow morning. Thanks.

                  Hi Jay,

                  you are right. It works fine for war deployments. But nor for ear deployment.

                   

                  I create a simple ear file and move your war file in it. Delete jboss-deployment-structure.xml from war and move it it ear/META-INF .

                   

                  With the golbal module definition in standalone.xml it works fine but with module definition in jboss-deployment-structure.xml it fails.

                   

                  I look for the version of jboss-modules in 7.1.1.Final it was 1.1.1.GA. The version of  7.2.0.Final is 1.2.0.CR1. So I assume there is a Bug for EAR Deployment.

                   

                   

                  UPDATE:

                   

                  I try the same deployment with the latest stable build of jboss-as-8.0.0.Alpha1-SNAPSHOT. But still the same result the modules version here is 1.2.0.CR2

                    It's the war that needs that dependency. See these for details on how to set it up:

                      Hi Jaikiran,

                       

                      I try it with the export="true" flag. But that's is the same as I define drools as global module.

                       

                      I have problems with log4j with that approach. Something in drools initialiazie log4j before I do it .

                       

                      The strange thing is that this works in 7.1.1.Final. Without the export flag

                        It's similar. But I would recommend either using the export flag or explicitly defining the dependency for the sub deployment. I wouldn't suggest using global module.

                        You mean if you use export, you start seeing a problem? Can you post the entire stacktrace and the updated jboss-deployment-structure.xml?

                        Based on what you are saying, it might have to do with the logging changes that were done post 7.1.1.Final. What happens if you start the server with -Dorg.jboss.as.logging.per-deployment=false

                          Based on what you are saying, it might have to do with the logging changes that were done post 7.1.1.Final. What happens if you start the server with -Dorg.jboss.as.logging.per-deployment=false

                           

                           

                          I had have switch back to 7.1.1.Final I'll switch back to 7.2.0.Final to tell you more.

                           

                          My Problem with Log4j and Jboss logging is that I can't use the addivity flag of the log4j loggers. The JBoss BridgeLogger ignore that falg. With other words this falg don't take a efect.
