Hi,
I had written a client which is trying to call the ejb dynamically using reflection api.
Instead of putting the home and remote interfaces in the classpath of the client
application I am trying to load these interfaces from jboss server using RMI codebase. For
this i had also added the security manager in my client so that it can load the interfaces
from jboss server. This thing is working in jboss-4.0.3SP1 completly, but it is not
working in jboss-eap-4.2 completely.
Client is loading the home interface but it is not loading the remote interface from
jboss-eap-4.2 while Client is loading both home interface and remote interface from
4.0.3SP1. Those interfaces are present in RMI codebase URL(I am able to download those
interfaces with the help of browser in that URL)
My Client code is as follow:
public class Client
{
public static void main(String args[])
{
System.setProperty("java.security.policy","D:\\VB\\policy.all");
SecurityManager sm=new SecurityManager();
System.setSecurityManager(sm);
String
jndiName="CFFESBean",homeInterfaceName="nsdg.client.CFFESHome",remoteInterfaceName="nsdg.client.CFFESRemote";
String remoteMethodName="initialise";
Properties ps=new Properties();
ps.put(InitialContext.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
ps.put(InitialContext.PROVIDER_URL, "jnp://localhost:1099");
ps.put(InitialContext.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
try
{
Context ctx=new InitialContext(ps);
System.out.println("1");
Object homeObject=ctx.lookup(jndiName);
System.out.println("2");
EJBHome ejbHomeObject=(EJBHome)PortableRemoteObject.narrow(homeObject,EJBHome.class);
EJBMetaData ejbMetaData=ejbHomeObject.getEJBMetaData();
Class homeInterfaceClass=ejbMetaData.getHomeInterfaceClass();
System.out.println("ejbHomeObject= "+ejbHomeObject);
Class remoteInterfaceClass=ejbMetaData.getRemoteInterfaceClass();
System.out.println("Remote Interface Class= "+remoteInterfaceClass);
Method homeInterfaceMethod = homeInterfaceClass.getMethod("create",null);
homeInterfaceMethod.setAccessible(true);
System.out.println("3");
EJBObject remoteObject=(EJBObject)homeInterfaceMethod.invoke(homeObject, null);
System.out.println("4");
Method remoteInterfaceMethod = remoteInterfaceClass.getMethod(remoteMethodName,null);
remoteInterfaceMethod.setAccessible(true);
Object returnObject=remoteInterfaceMethod.invoke(remoteObject, null);
System.out.println("returning");
}catch (NamingException e)
{
System.out.println("Inside Naming Exception");
e.printStackTrace();
}catch (Exception e)
{
System.out.println("Inside Exception");
e.printStackTrace();
}
}
}
And the output is as follow:
1
2
ejbHomeObject= CFFESBeanHome
Remote Interface Class= interface nsdg.client.CFFESRemote

What can be the solution of this problem so that it will work completly with
jboss-eap-4.2
