NoClassDefFoundError when call EJB 2.1 in AS7

[huasonator]

Hi all,

When I call EJB 2.1 ,i dont have problem with de lookup, is work, but when i need create de bean, i get the next error:

java.lang.NoClassDefFoundError: Could not initialize class org.jboss.security.SecurityAssociation

This class is found in jbossall-client.jar, this jar is put in WEN-INF/lib, within example.war. I read de classloader documentation and the war is isolate, what is the problem? I can not get remote interface in AS7?

Regards...

[sfcoy]

Is the EJB actually remote?

Or is it deployed in the same server instance?

Or is it deployed in the same application (EAR)?

[huasonator]

The EJB 2.1 is deployed in jboss-4.0.5.GA in other machine, i can get the remote interface if i do the lookup from other server with the same jboss-4.0.5.GA, but when i try get the same remote interface within jboss-as-7.1.1.Final i got the java.lang.NoClassDefFoundError: Could not initialize class org.jboss.security.SecurityAssociation, this happens when i tried to create the remote interface ( i dont have problems get in the home interface).

Any ideas?

[wdfink]

Maybe you need to exclude security classes from AS7 via deployment-structure.xml

[huasonator]

I dont understand because the documentation say: "The war is considered to be a single module, so classes defined in WEB-INF/lib are treated the same as classes in WEB-INF/classes. All classes packaged in the war will be loaded with the same class loader." And i put jbossall-client.jar in WEB-INF/lib, this jar contains org.jboss.security.SecurityAssociation, for other hand i read that as org.jboss.security.SecurityAssociation was removed form AS7.

Anayway i put the next deployment-structure.xml in my WEB-INF/lib:

<jboss-deployment-structure>

  <deployment>

    <exclusions>

      <module name="org.jboss.security" />

    </exclusions>

          </deployment>

</jboss-deployment-structure>

But i get the same result...

[huasonator]

Next code works fine,i create a simple test with a main class and the code run (dependece jbossall-client.jar), but if i put the same code running on AS7 i get the problem.

Code:

final Properties properties = new Properties();

properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

properties.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

properties.put(Context.PROVIDER_URL, "jnp://192.168.0.138:1099");

Context context = new InitialContext(properties);

Object objectLookup = context.lookup("ExampleJNDI"); // it works fine

Object ejbService = objectLookup.getClass().getMethod("create", new Class[]{}).invoke(objectLookup, new Object[]{}); // throws Exception

Object result = ejbService.getClass().getMethod("exampleMethod", new Class[]{}).invoke(ejbService, new Object[]{});

System.out.println(result);

Any Ideas?

[sfcoy]

I suspect that there is bound to be some class collisions in the JBoss 4.0.5 jbossall-client.jar and JBoss 7.x.

It's worth trying a bit of elimination to see if we can get it to work.

Try replacing jbossall-client.jar with jnp-client.jar to start with. The jbossall-client.jar is an amalgamation of the client jars in your 4.0.5 $JBOSS_HOME/client directory.

If we can get it failing with class not found exceptions, then we can gradually try to add in only the relevent client jars.

[huasonator]

I remove jbossall-client.jar from WEB-INF/lib and put the necessary jar (jnp-client.jar,jboss-common-client.jar,jboss-j2ee.jar,concurrent.jar,jboss-client.jar,jboss-serialization.jar,jboss-remoting.jar,jbosssx.jar,jboss-transaction-client.jar) but i get the same error.

Really I do not understand why this happens, I prove the same WAR in jboss-6.1.0.Final and works fine. The problem is only wint AS7.

[sfcoy]

We need to do this one jar at a time, not all at once...

[sfcoy]

How do you know what is necessary? The jbossall-client.jar would have been completely redundant in your JBoss 4.0.5 client app deployment.

[huasonator]

I did what you told me, the jar with the problem is jbosssx.jar, this jar has the class SecurityAssociation , when i remove i get the next stack trace.

When i put the jar, i get the same error Caused by: java.lang.IllegalAccessError: tried to access class org.jboss.security.SecurityActions from class org.jboss.security.SecurityAssociation

I gave up

[sfcoy]

I suspected that you would get this kind of problem.

I think that if you really want to get this to work you could try and build your own version of jbosssx.jar against the security APIs in JBoss AS 7.

[sfcoy]

For what it's worth, I've tried your scenario out myself and tried to configure the classloader to avoid issues.

Unfortunately, it is initially failing with a

{code}
java.lang.IllegalAccessError: tried to access class org.jboss.security.SecurityActions from class org.jboss.security.SecurityAssociation
          org.jboss.security.SecurityAssociation.<clinit>(SecurityAssociation.java:141)

          org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62){code}

which suggests that JBoss AS 7 security configuration is actually preventing access to theses classes.

Therefore, I don't think even my previous idea is likely to work for you.

[huasonator]

Yep... tonight i will give other perspective to this problem... try to access with new jboss-remote-naming with org.jboss.naming.remote.client.InitialContextFactory i think it should work... or maby the class valid the new format for the JNDI...

https://docs.jboss.org/author/display/AS71/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project

What do you  think?

[sfcoy]

Hmm. I just noticed that it's a java.lang.IllegalAccessError, which means we have some class incompatibilities.

It may be possible to update org.jboss.proxy.SecurityInterceptor so that it works with the JBoss 7 security APIs.

(I really have to stop answering forum questions at 1:30 in the morning...)
