remote ejb call EAP 6.1->AS6: NoClassDefFoundError: Could not initialize class org.jnp.interfaces.NamingContext

[devsisodia]

Hello,

My application has ejb client inside EAP 6.1 that need to invoke remote ejb hosted on Jboss AS6. For this i created module in eap6.1 and in the module.xml file listed resources as all the jars present in JBOSS_HOME/client directory.

Here i am getting NoClassDefFoundError: Could not initialize class org.jnp.interfaces.NamingContext.

Quick help will be appreciated.

Approach followed is mentioned here of part Ralph Jennings     May 24, 2012 6:39 AM and here

created module for AS6Client jars and copied ALL jars from AS6_HOME/client and created module.xml.  Then using jboss-deployement-structure.xml added dependency to these AS6Client jars.

Exclusions on module "org.picketbox".

I have attached module.xml and server logs server.zip

--------------------------------------------------------------------

Because in above approach we are including ALL client jars from AS6 there are some classloading conflicts on cxf package(my application has cxf dependency). AS6Clients jars have one version and EAP 6.1 runtime provides other version. So to resolve this tried to figure out what all client jars are really necessary and i found it here . After doing this I am getting exception like mentioned in attached file  'serverErrorWhenMinClient6JarsUsed.txt'

[devsisodia]

I added required AS6Client jars to application lib directory then appl is not getting deployed with exception that the jar lib/jboss-ejb3-async-impl.jar file has xml file(lib/jboss-ejb3-async-impl.jar/META-INF/ejb3-async-jboss-beans.xml) that it cannot parse.

For successfully communicating between EAP 6.1 installed ejb client with AS6 installed ejb following is what I found to work:

1. Remove jboss-ejb3-async-impl.jar/META-INF/ejb3-async-jboss-beans.xml and package jboss-ejb3-async-impl.jar. Without removing the xml file deployment fails with exception “Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS017082: Exception while parsing POJO descriptor file: "/content/glowpoint-integration-ear.ear/lib/jboss-ejb3-async-impl.jar/META-INF/ejb3-async-jboss-beans.xml"”

It is a hack that worked for me.

2. exclusion for <module name="org.picketbox" slot="main"/> in <APP>/META-INF/jboss-deployment-structure.xml

3. put all jars mentioned in attached module.xml into lib of application.

<resource-root path="concurrent.jar"/>

<resource-root path="jboss-aop-client.jar"/>

<resource-root path="jboss-aspect-jdk50-client.jar"/>

<resource-root path="jboss-common-core.jar"/>

<resource-root path="jboss-ejb3-async-impl"/>

<resource-root path="jboss-ejb3-async-spi.jar"/>

<resource-root path="jboss-ejb3-common-client.jar"/>

<resource-root path="jboss-ejb3-context-spi"/>

<resource-root path="jboss-ejb3-core-client.jar"/>

<resource-root path="jboss-ejb3-proxy-impl-client.jar"/>

<resource-root path="jboss-ejb3-proxy-spi-client.jar"/>

<resource-root path="jboss-ejb3-security-client.jar"/>

<resource-root path="jboss-integration.jar"/>

<resource-root path="jboss-metadata-ear.jar"/>

<resource-root path="jboss-remoting.jar"/>

<resource-root path="jboss-security-spi.jar"/>

<resource-root path="jboss-serialization.jar"/>

<resource-root path="jbosssx-client.jar"/>

<resource-root path="jnp-client.jar"/>

Note: if you are getting security classcast exception like  " java.lang.ClassCastException: org.jboss .security.plugins.JBossSecurityContext cannot be cast to org.jboss.security.SecurityContext" then step 2(above) and restarting the server should help.
