Hello Friends

I am stuck in a very strange kind of problem.
My application is having the following ejb3, jsf & JBoss-4.0.4.GA
I have got a jsp page which takes the user name & password of the user. The fields are binded to user object in the backing bean[scope is request]. When the user does a login the method in the backing bean is getting called. On doing a lookup[UserService userService = (UserService) context.lookup("UserServiceImpl/remote");] in the backing bean is throwing exception. But the same lookup works fine when tested in TestClass.


EXCEPTION:
javax.naming.CommunicationException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.net.MalformedURLException: no protocol: Deployment_5Dec/Delete/jboss-4.0.4.GA/server/default/deploy/Test.war/WEB-INF/classes/]

Code for doing the lookup

try
{
Hashtable <String,String> env = new Hashtable<String,String>();
env.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "jnp://localhost:1099");
env.put("java.naming.factory.url.pkgs","org.jboss.namingrg.jnp.interfaces");
InitialContext context = new InitialContext(env);
UserService userService = (UserService)context.lookup("UserServiceImpl/remote");
user = userService.authenticateUser(user);
if(user != null && user.getUserId() != 0)
{
System.out.println("Logged in successfully");
}

}catch (Exception e)
{
e.printStackTrace();
}

mysql-ds.xml

Hi

I want to add some more information here. The database, WAR & JAR(EJb3) all are on the same machine. The code worked fine on my desktop, but it is failing when I do the deployment on the laptop.

I know it is strange but this is where I am getting stuck.

Can anyone provide me leads for the same.....

Thanks
Amit
