Hi, Romain,
I am not using Tomcat, just openEJB 3.1.4, ejb jar is copied into app
folder. I tried : properties.put(Context.PROVIDER_URL,
"ejbd://localhost:4201"), still doesn't work.

Hi Edward,
i guess yo are trying to lookup an object in tomcat (because of the http
url), if tomcat is on the 4204 port the url should be
http://localhost:4204/<openejb
context name>/ejb, it is often http://localhost/openejb/ejb.
If you are not using tomcat can you please explain us how you run your
server.

Hi, ALL,
I am trying to write a standalone EJB client, but failed.
I have a standalone OpenEJB in C drive, I place simple-stateless-1.0.jar
into its app folder. This jar is from OpenEjb example. It works, from log I
can see,
///////////////
2011-05-09 21:07:30,825 - INFO - Jndi(name=CalculatorImplLocal) -->
Ejb(deployment-id=CalculatorImpl)
2011-05-09 21:07:30,827 - INFO - Jndi(name=CalculatorImplRemote) -->
Ejb(deployment-id=CalculatorImpl)
2011-05-09 21:07:30,856 - INFO - Created Ejb(deployment-id=CalculatorImpl,
ejb-name=CalculatorImpl, container=My Stateless Container)
2011-05-09 21:07:30,856 - INFO - Deployed
Application(path=C:\openejb-3.1.4\apps\simple-stateless-1.0.jar)
///////////////
Now the clinent is
//////////////////////
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
//properties.put("java.naming.provider.url",
"ejbd://localhost:4201");
properties.put("java.naming.provider.url", "
http://localhost:4204/ejb";);
InitialContext initialContext = new InitialContext(properties);
Object object = initialContext.lookup("CalculatorImplRemote");
/////////////////////////////
It always give me error:
