      Hi,

       

      I was installed JOSSO 1.8.9 to the JBoss AS 7.1.1.Final. Installation of JOSSO gateway and JOSSO agent looks ok with known issues for examle from this :

      http://codepk.tumblr.com/post/101409947356/josso-agent-1-8-installation-in-jboss-7-1.

      I have problem with starting of the josso-partner-jboss7-app-1.8.9.ear which is example of applications used JOSSO sso. On the deploy this error appears:

      It takes no sense to me. This is module.xml from /jboss-as-7.1.1.Final/modules/org/apache/commons/loging/main/

       

      <?xml version="1.0" encoding="UTF-8"?>
<module-alias xmlns="urn:jboss:module:1.1" name="org.apache.commons.logging" target-name="org.slf4j.jcl-over-slf4j"/>

       

      So commons logging using implementation from slf4j.

      Here is module.xml of org.slf4j.jcl-over-slf4j module:

       

      <?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.slf4j.jcl-over-slf4j">
    <resources>
        <resource-root path="jcl-over-slf4j-1.6.1.jar"/>
        <!-- Insert resources here -->
    </resources>

    <dependencies>
        <module name="org.slf4j"/>
    </dependencies>
</module>

       

      and in jcl-over-slf4j-1.6.1.jar is visible org.apache.commons.logging.Log class.

       

      It is problem with class loading with EAR? How can I fix it? Many thanks for any help.

          Does the EAR you're deploying also contain a commons-logging library? It looks like it might. Try removing that library and see if that works.

            Thanks for reply James!

             

            That is good point, Unfortunaly commons-logging library is not included eigther in the ear or war, but I found not necesseary library jcl-over-slf4j.jar there. Jboss have it between modules. I marked it as provided and build ear again. That leads me to find another commons-logging and jcl-over-slf4j libraries or theirs references. I found that module org.josso have commons-logging library is in the module.xml and in the module folder. I removed library from the module folder. I removed reference from resource section of the module.xml, but I left reference in the dependency section:

             

            <dependencies>
     ...
     <module name="org.apache.commons.logging"/>
</dependencies>

             

            It is correct? Or I should remove it? The library commons-logging.jar is not visible on the server and the library jcl-over-slf4j.jar is only in the org.slf4j.jcl-over-slf4j.module and referenced from the org.apache.commons.logging.module. In this state problem still persists.

              If I understand it correctly you will want to keep the org.apache.commons.logging dependency on your org.josso module.xml. You'll also want to remove the commons-logging library from the resource in the org.josso module.xml. Your deployment should automatically get the org.apache.commons.logging dependency added.

               

              If you're still seeing "previously initiated loading for a different type with name "org/apache/commons/logging/Log"" error then there are still two libraries being loaded.

                Yes, you understand what I want. Thank you very much for your time, I think, I am understanding principles how it should work. Unfortunately I must move our project to Wildfly so attempts with Jboss 7 were stopped. On the Wildfly with Josso I must solve some problems with configuration of the josso security domain first. Thanks for your time again.

                  FWIW the commons-logging module stuff should work the same in WildFly.
