    Wildlfy module.xml Configuration for one java class

    Julián Pérez Newbie

      I am testing an java application and getting this error:

       

       

          org.jboss.naming.remote.protocol.NamingIOException: Failed to rebind [Root exception is java.io.IOException: java.lang.ClassNotFoundException: de.brockhaus.userMgmt.control.process.SomeProcess from [Module "org.jboss.remote-naming:main" from local module loader @ed17bee (finder: local module finder @2a33fae0 (roots: C:\Program Files\jboss\wildfly\modules,C:\Program Files\jboss\wildfly\modules\system\layers\base))]]

          ...

          Caused by: java.io.IOException: java.lang.ClassNotFoundException: de.brockhaus.userMgmt.control.process.SomeProcess from [Module "org.jboss.remote-naming:main" from local module loader @ed17bee (finder: local module finder @2a33fae0 (roots: C:\Program Files\jboss\wildfly\modules,C:\Program Files\jboss\wildfly\modules\system\layers\base))]

       

       

      This is a part of my pom.xml maven file where I have added the following dependency:

       

       

          <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-jar-plugin</artifactId>

                <version>2.3.1</version>

                <configuration>

                    <archive>

                      <manifestEntries>

                          <Dependencies>org.jboss.remote-naming</Dependencies>

                      </manifestEntries>

                    </archive>

                </configuration>   

              </plugin>

       

       

      So my purpose is modifying the module.xml file of

       

       

      C:\Program Files\jboss\wildfly\modules\system\layers\base\org\jboss\remote-naming\main

       

       

          <module xmlns="urn:jboss:module:1.3" name="org.jboss.remote-naming">

              <resources>

                  <resource-root path="jboss-remote-naming-2.0.4.Final.jar"/>

                   <resource-root path="de/brockhaus/userMgmt/control/process"/>

              </resources>

         

              <dependencies>

                  <module name="javax.api"/>

                  <module name="org.jboss.ejb-client" optional="true"/>

                  <module name="org.jboss.remoting"/>

                  <module name="org.jboss.logging"/>

                  <module name="org.jboss.marshalling"/>

                  <module name="org.jboss.marshalling.river"/>

                  <module name="de.brockhaus.userMgmt.control.process"/>

              </dependencies>

          </module>

       

       

      But this also gives errors. I would like to know how to change this above xml file in order to achieve the things working right.

          First thing we are not supposed to edit the JBoss provided default modules like "org.jboss.remote-naming" .  which is happening in your case.

           

          If your class needs access to the  org.jboss.remote-naming  module then add it in the dependencies section of your custom module as following:

           

          Can you try the following approach to see what happens:

           

             <module xmlns="urn:jboss:module:1.3" name="de.brockhaus.userMgmt.control.process">   <!-- your custom module -->
                  <resources>
                       <resource-root path="."/>    <!--  Here . represents the current directory contents -->
                  </resources>
                  <dependencies>
                      <module name="javax.api"/>
                      <module name="org.jboss.ejb-client" optional="true"/>
                      <module name="org.jboss.remoting"/>
                      <module name="org.jboss.logging"/>
                      <module name="org.jboss.marshalling"/>
                      <module name="org.jboss.marshalling.river"/>
                      <module name="org.jboss.remote-naming"/>    <!-- Notice if your class needs access to this module -->
                  </dependencies>
              </module>
          
          

           

           

          If your fully qualified classname is "de.brockhaus.userMgmt.control.process.SomeProcess"   then you do not need to include the whole path in the resource path    <resource-root path="de/brockhaus/userMgmt/control/process"/>

          Just say "<resource-root path="."/>"

           

          Also can you please post the directory structure of your custom module "de.brockhaus.userMgmt.control.process" ? along with it's module.xml file here?

          Regards

            Firstly, thank you for your help. The reason why I have modified the org.remote-naming JBoss module is due to the error message. I have understood that the solution for that error was to modify it. However, I have not understood why wildfly can not find that class when the jar of the project was created without problems with a maven build (clean install). As I told you in the other post, now I get this error:

            I have create a jboss module de.brockhaus.userMgmt in whose main directory I have put the jar of the maven build (BRO130_3_7_ResourceBinder-solution.jar) and this is the module.xml content:

            <module xmlns="urn:jboss:module:1.3" name="de.brockhaus.userMgmt">

             

                <properties>

              The error which you mentioned like [WFLYNAM0043: Naming context is read-only]   you will get if you will try to bind custom objects to read only contexts like  "java:module" or "java:module", "java:comp" ..etc"

               

                                   InitialContext ic = new InitialContext(); 
                                   aaa.bbb.Test  test = new aaa.bbb.Test(); 
                                   ic.rebind("java:app/SomeProcess",test);     // WRONG 
                                                //  OR 
                                   ic.rebind("java:module/SomeProcess",test);        // WRONG 
                                                //  OR 
                                   ic.rebind("java:comp/SomeProcess",test);     // WRONG
