    question about jmx-console error

    null null Newbie

      Hi all,

      I've installed the preinstalled version(jboss-3.2.1_nukes-1.0.0alpha) of nukes.

      However, when i goto jmx-console and click the Apply Changes button in core module, it has some error and show the follow message to me:

      HTTP ERROR: 500 Internal Server Error
      RequestURI=/jmx-console/HtmlAdaptor

      How can i solve this problem?
      Thanks

      Chris

          I think you can use the Nukes JMX console when you log in as admin.

            Thanks for your reply. But I'm sorry, I don't know what you mean. I just goto http://localhost:8080/jmx-console and there is no need to login.

            would you give me more details?

            Thanks very much!

              there is an jmx-module for nukes.

              jmx-console need's JDK (..javac) not only JRE to build some servlets from JSP's ( i think )

                this is the jmx module : you go in nukes/jmx then type sh build.sh deploy. then when you login as admin you should see the a jmx entry management in the main menu.

                  I also have the above problem with the jBoss jmx consule.

                  I am not sure that the nukes jmx module is included in the alpha bundle that is linked to from the OnJava article as I have a message jmx module not registered in my server log (tried index.html?module-jmx)

                  I presume the instructions you have posted to build the jmx-module refer to the latest source from cvs on a linux /unix platform ?

                    you really should use a CVS version :-), after forums I will setup a real release.

                      I also need a "Real Release" ASAP!! I need one for mySQL / Linux.

                        Taking Julien's advice, I got rid of my installed jboss-3.2.1_nukes-1.0.0alpha version of Nukes.

                        I followed the instructions at

                        http://www.jboss.org/index.html?module=html&op=userdisplay&id=developers/projects/nukes/tutorial

                        to install a CVS version, build it on my RedHat box, then redeploy. The steps specified in the
                        link above are outlined below, along with changes I had to make or issues that came up.

                        -----
                        Step 1: Get Nukes
                        Obtained the CVS version using the command specified in the tutorial:

                        cvs -d :pserver:anonymous@cvs.jboss.sourceforge.net:/cvsroot/jboss co nukes

                        Works great.

                        -----
                        Step 2: Get the server

                        I had already downloaded and installed JBoss-3.2.2RC4 instead of JBoss-3.2.2RC2

                        -----
                        Step 3: Server Setup

                        Make sure you have the $JBOSS_HOME environment variable set correctly.
                        Also make sure that $JAVA_HOME/bin is in your $PATH.

                        -----
                        Step 4: Nukes Build
                        Several tweaks had to be done during this step.

                        a. I'm using mySQL instead of hsql, so I had to change the contents of the nukes/build/local.properties.

                        nukes.datasource=NukesDS
                        nukes.type-mapping=mySQL
                        nukes.mergedir=mysql

                        A pattern for these settings was found in nukes/build/etc/local.properties-mysql

                        b. The files you need to create the nukes mySQL db are in /nukes/nukes/src/resources/mysql

                        The instructions tell you to run mysql < prepare.ddl, then mysql < setup.ddl to create the mysql db access
                        privileges and the nukes database. These files generated errors, however, so I combined the setup into one file and made some mods to get rid of the errors. Here are the contents of my single setup file. The privileges may not be appropriate for your application.

For example, people with the right admin privileges can view this very page and click on the \"edit page\" button at the
                        top that takes you to a edit page and then commits/rollsback/versions the page and makes it production available immediately. All data is stored in the database. \r\n\r\n\r\n Some technical characteristics include\r\n\r\n\r\nLeverages JBoss JMX microkernel, that manages component lifecycle, hot deploys\r\ncomponent at runtime. You can dynamically deploy a new \"block\" on the right navigation of the site and the dynamic nature of JBoss let\'s you do so while Nukes application is running\r\n\r\nEJBs, they are for us easy to use components. CMP 2.0 is very mature\r\nand abstracts the underlying data store, providing a portable mapping.\r\nThey can be easily tuned for each usage.

                        c. I've changed my jdbc driver from MM.MySQL to MySQL Connector/J 3.0.7 Stable. You can use this new version by downloading mysql-connector-java-3.0.7-stable-bin.jar from http://www.mysql.com/downloads/api-jdbc-stable.html and placing it in $JAVA_HOME/jre/lib/ext.

                        This change requires a change the <driver-class> parameter in the nukes-ds.xml file, as shown below. After the change is made, copy nukes-ds.ddl to $JBOSS_HOME/server/default/deploy

                        Well, I was hoping that the jmx-console problem would be solved, but it ain't.

                        I can now browse to the Nukes home page, after the new build and installation, but I still don't see any jmx-console access link. The jmx-console module is still not registered. So, how do I register it?

                        Finally, I still can't access the jmx-console using .../index.html?module=jmx-console, and browsing directly to the jmx-console, then trying to make a change generates the original error.

                        Help Me.

                          First, thanks for the feed back. I have just updated the tutorial. Actually I split it in 2 : installation (revamped with mysql) and development.

                          There are two JMX consoles :

                          The one that come with JBoss : localhost:8080/jmx-console

                          The one that comes with nukes : this a nukes module that you have to build and deploy in server/default/nukes :

                          cd nukes
                          cd jmx
                          sh build.sh deploy

                          then you can access it when you are logged in as admin, there should be a link to it from the menu block when you are admin,

                            Presto!!!

                            Thanks Julien.

                            P.S.
                            When I tried to build "All" in nukes/build, it failed. Should it have?

                            Thanks,

                              I never used it actually. The build system is stolen from jboss server sometimes there are some things I don't know what they are usefull for.

                                If it helps anyone I have also followed the installation instructions to pull the latest version of nuke from CVS and install it.

                                I have installed the jmx-console within nukes by the following steps

                                1. Changing to the jmx-module subdirectory
                                2. Run build
                                3. Run build deploy

                                This automatically deploys the jmx-module to jboss. It needs a nukes subdirectory to be present under the jboss deploy directory - for some reason I didnt have this but if you create it then it seems to work fine

                                The same approach seems to work for the other modules as well. However, if the module you are trying to deploy needs to have some database tables present then you need to create them first. Insert the folllowing step

                                2a - Change to the output/resources/"sub directory for you database" and open the .ddl file. Execute the sql it contains against your database to create and populate the required tables for the module (e.g. using squirrel as suggested in the installation instructions)

                                Sorry if any of the paths in this post are incorrect as I am doing it from memory - Soneone can amend them if they are.

                                I am sure there must be an easier way to automatically deploy the modules - I am sure someone will let me know !

                                Also does anyone know if there is a module that provides forums (like this one) ?
