    Problem with new modules deploy

    Paolo Newbie

      I deployed a new sample module for a project in my university, but nukes tell me:
      11:14:28,116 INFO [MainDeployer] Starting deployment of package: file:/C:/jboss
      11:14:28,186 WARN [ServiceConfigurator] Failed to complete install
      java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.Nukes.cor

      What's wrong?

          did you package the class files w/ the sar?

            For the sar (effectively jar) package i used Netbeans and i followed step by step the instructions from the article on O'Reilly (the one linked in the main page of nukes project).
            Into the archive i put the class as a leaf of the entire path of the package (org/jboss/nukes/core/.../LinkModule.class).

            I don't understand what's wrong and what is this ClassLoader not found...

            thanks for the help :-)

              do you have the nukes core deployed? are you using any 3rd party libraries in your code that aren't deployed in jboss?

              i have seen instances where jboss masks that fact one of your dependencies is missing, but it reports it as one of your own classes.

                I'm using JBoss 3.2.3RC1 with Nukes 1.0.0 prepared for MySQL. The server starts without problems.

                This is the code:

                package org.jboss.nukes.addons.modules.linkmodule;

                import org.jboss.nukes.module.*;
                import org.jboss.nukes.html.*;

                public class LinkModule extends ModuleSupport {

                /** Creates a new instance of LinkModule */
                public LinkModule() {

                public void main(Page page) {
                page.print("<div align=\"center\">");
                page.print("Hello World!");

                public void action(Page page) {
                page.print("This is action method");


                Thanks a lot for your support!

                  can you send the sar (including source) to the address in my profile and i'll take a look at it on my end.

                    In your profile there's the default fake email. However I'm the webmaster of some little sites, so I've upload the sar archive in www.aimc.mn.it/linkmodule-service.sar

                    See you soon and... tanks again!

                      sorry about that - i thought i had a real email address in there. in any case, two things.

                      1) are you deploying your module into the "nukes" directory instead of the "deploy" directory? only the "nukes.ear" and the datasource and be deployed in the "deploy" directory. all other modules need to live in the "nukes" dir.

                      2) your jboss-service.xml file is incorrect. it should look like this:

                      <?xml version="1.0" encoding="UTF-8"?>
                       <attribute name="DisplayName">Modulo dei collegamenti</attribute>
                       <attribute name="Description">Descrizione del modulo dei collegamenti</attribute>

                      provided you have the "nukes.ear" deployed and you place your module in the "nukes' directory, it should deploy after you make the adjustments to jboss-service.xml.

                      also, i'd recommend upgrading to jboss 3.2.3 and test out against the Nukes_1_1_0_RC1 tag b/c the 1.1 release will be coming very soon.

                        Thanks, it deploy correctly now! The only problem is that it's invisible in module's menu under nuke's administration. However it's visible when loaded directly with the url http://localhost:8080/index.html?module=LinkModule and in the Jmx console.

                        Thanks a lot! When my work at university with nukes will ben done, I'll write some docs for other novices that will be in trouble just like me!

                        See you soon

                          you don't have any entries in the file to add links to the menu. look at one of the other component's descriptors for an example.

                            I am new to jboss nukes and just check the source code from cvs and build/deploy it myself.

                            I have deployed successfully the TemplateModule and also i can access this module by the type the following link manually:


                            However, i want to know how to make this new module displayed in the menu as other modules such as news etc when a user access this web site.

                            Thanks a lot

                              I already find it out.

                              JbossNukes is powerful!

                                I havend't found it out yet. Could someone give me a hand on addind modules to the menu? Thanks.

                                  You must add Configuration Attribute to your jboss-service.xml for your module.

                                  <attribute name="Configuration">
                                   name="Name of the Method from your module which will be called"
                                   display-name="Name of the link show in menue"
                                   description="Alt tag of the link"
                                   image="Image show in MYAccount Section"

                                  Hope this helps
