Re: Geronimo 2 EJB3 Remote Access Example
Hi, I tried this example and it works. But this is example is with a web client. I'd like to have a fat client and wants to access the session bean (over RMI-IIOP ? I'm not sure). But I don't know the right JNDI lookup string? This is my problem. Any solutions? Thanks vhnguy2 wrote: There are some sample applications on our wiki.

Re: Geronimo 2 EJB3 Remote Access Example
Hi,
thanks a lot, now it works. But not completely
When I'm trying the following code:
public class TestClient {
public static void main(String[] args) {
Context context;
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
org.apache.openejb.client.RemoteInitialContextFactory);
properties.setProperty(Context.PROVIDER_URL,
ejbd://localhost:4201);
properties.put(java.naming.security.principal, system);
properties.put(java.naming.security.credentials, manager);
try {
context = new InitialContext(properties);
IProjectDSP projectDSP = (IProjectDSP)
context.lookup(ProjectDSPRemote);
// Project p1 = new Project();
// p1.setName(Test);
// projectDSP.createProject(p1);
} catch (NamingException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
I'm getting this exception:

Maybe ProjectDSP has some security settings on it. Try adding this line to it

Re: Geronimo 2 EJB3 Remote Access Example
Hi,
this was not the problem, but I found the solution.
I had a different openejb JAR File in the build path than the server was
working with.
So the serial version id was different and this was the problem.
Thanks @all for your help. Now its working.

There are some sample applications on our wiki. For a session bean sample, you might want to take a look at this: http://cwiki.apache.org/GMOxDOC20/very-simple-session-ejb-example.html. There are other samples there too if you're interested. Thanks, Viet On Jan 23, 2008 5:14 PM, xypher [EMAIL PROTECTED] wrote: Hi, I'm relatively new to Geroimo 2 and EJB3.
