    Missing module system:main in JBoss7.1.Beta1

    Gonne Martens Novice

      Hi,

       

      I am missing module system:main since trying to use JBoss7.1.Beta1, because I need access to com.sun.net.ssl.internal.ssl.Provider.

       

      Regards,

      Gonne

          Afais, system module has been removed -- imo you need a diff way to get this class; e.g. check sun.jdk module.

            According to the documentation the module sun.jdk is always added, but it does not include the sun ssl classes.

             

            I do not know what the recommended way for this problem is.

            As workaround I added the package path to the module.xml of the sun.jdk module:

            ...
            <dependencies>
                <system export="true">
                    <paths>
                        ...
                        <path name="com/sun/net/ssl/internal/ssl"/>
                    </paths>
            ...
                </system>
            </dependencies>
            ...

              Yes, I think that's one of the ways to do it -- and not really a hack.

              Or, you could create your own module -- similar to sun.jdk.

                Sorry to tack this onto the end of the thread, but I'm getting the same "Module system:main is not found in local module loader", despite not having any "com.sun" refs (in any parent classes), and this is only after upgrading from 7.1.0.Alpha2. Can't find any other references to this problem, and nothing in the release notes.

                 

                Very weird.  I can't see anything different about the class it's complaining about.

                 

                Any ideas?

                  Do you have a dependency defined to the module 'system' in a jboss-deployment-structure.xml or the MANIFEST.MF of your EAR or as global module in your standalone.xml?

                    Not in MANIFEST.MF, but I notice that a module I added a while back has "<module name="system"/>" in its descriptor - and that this module is referred-to within the servlet class that is failing...

                     

                    I'll try removing the module's dependency on 'system' and see if that fixes it. Thanks for the suggestion!

                      If you need anything from system classpath, see how "org.jboss.modules" does it.

                      Since JBoss Modules is what's on the system classpath, along with JDK of course.

                        ...
                        

                         

                        I did have a patch which filled in all of the major sun.jdk paths, but I guess it never made it upstream.  But yes I'd say this is the proper fix.
