jboss-app.xml for class loading issue

[ohmygod]

Hi jaikiran,

Can you help me on writing the jboss-app.xml according to my application deployment or what else needs to be added on my current jboss-app.xml? I heard you tested jboss-app.xml and it worked perfectly in another thread. Pasting one piece of the the jar conflict error for your reference:

11:26:43,437 ERROR [[/globalsight]] Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl cannot be cast to javax.xml.parsers.SAXParserFactory
        at javax.xml.parsers.SAXParserFactory.newInstance(SAXParserFactory.java:128)

        at com.sun.faces.config.ConfigureListener$WebXmlProcessor.scanForFacesServlet(ConfigureListener.java:670)

My current jboss-app.xml: (located at deploy/globalsight.ear/META-INF)

<!DOCTYPE jboss-app PUBLIC
    "-//JBoss//DTD J2EE Application 5.0//EN"
    "http://www.jboss.org/j2ee/dtd/jboss-app_5_0.dtd">
<jboss-app >
    <loader-repository>
        org.w3c:loader=globalsight.ear
        <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
    </loader-repository>
   
</jboss-app>

And my application structure:

globalsight.ear

     cxe-ejb.jar

        META-INF

            ejb-jar.xml

            jboss.xml

            MANIFEST.MF

     globalsight-web.war

         WEB-INF

            web.xml

            lib (here are all my application's jars)

            classes

     META-INF

         application.xml

         jboss-app.xml

If you want the list of my jars in WEB-INF/lib, please let me know and I can paste them for you later.

I know you are busy, any help will be much appreciated though. I am really in urgent need for help.

I made the jboss-app.xml (under globalsight.ear\META-INF directory) like:

<!DOCTYPE jboss-app PUBLIC
    "-//JBoss//DTD J2EE Application 5.0//EN"
    "http://www.jboss.org/j2ee/dtd/jboss-app_5_0.dtd">
<jboss-app>
  <loader-repository>  
    com.example:loader=globalsight.ear  
    <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
  </loader-repository>
</jboss-app>

and made jboss-web.xml (under globalsight-web.war\WEB-INF directory) like:

<!DOCTYPE jboss-web PUBLIC  
        "-//JBoss//DTD Web Application 5.0//EN" 
        "http://www.jboss.org/j2ee/dtd/jboss-web_5_0.dtd">
<jboss-web>
<loader-repository>  
    com.example:loader=globalsight.ear  
    <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
  </loader-repository>
</jboss-web>

but got this error, could you advise? What order should I make in jboss-web.xml?

Caused by: org.jboss.xb.binding.JBossXBException: Failed to parse source: loader-repository not found as a child of jboss-web in unordered_sequence: security-role* max-active-sessions? webservice-description* class-loading? jacc-star-role-allow? message-destination* servlet* replication-config? passivation-config? context-root? security-domain? virtual-host* use-session-cookies? depends* {unordered_sequence jndiEnvironmentRefsGroup}?

adding node <class-loading java2ClassLoadingCompliance="false"> in front of <loader-repository> in jboss-web.xml fixes above error, but the classcast exception still happens.

11:26:43,437 ERROR [[/globalsight]] Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl cannot be cast to javax.xml.parsers.SAXParserFactory

Can Jboss 5.1.0 GA handle this problem now?

Hi Mike,

The order is in the "caused by

java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl cannot be cast to javax.xml.parsers.SAXParserFactory

Check that you are not packaging "xercesImpl.jar" with your jar. JBoss has its own copy.

Cheers.

hi there, i have the same jboss deployment problem while deploying my webapp under jboss-5.1.0.GA, i find these answer in an other internet post :

jboss jboss 5 web app packaging and classloading

I was facing classloading issue in Jboss 5.1 and the following worked for me like a miracle. Actually in jboss 5.x it is enabled by default so we need to comment that.

Unified classloader

In JBoss 4 in order to unify tomcat and jboss classloaders one had to change true

in jboss/server/default/deploy/jboss-web.deployer/META-INF/jboss-service.xml .

It is no longer the case in JBoss 5, instead the following has to be commented :

<!–

-1

javax.servlet,org.apache.commons.logging

in jboss-5.1.0.GA/server/default/deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml.
