Re: how to lookup ejb from jndi, in a stand alone client. ?

[David Jencks]

I get confused by the jndi "directory" part but suspect that one  
problem is your use of InitialDirContext rather than InitialContext.

Also are you sure you are using the openejb client library that goes  
with the server?  While we've tried to keep compatibility with older  
versions there may have been some changes in the authentication  
bits.... I know there were in the code if not the protocol.

Hi All,

in Gmo 2.1, i want to lookup a EJB from a standalone client

i write this code :

        Properties environment = new Properties();
        environment.put("java.naming.factory.initial",  
"org.openejb.client.RemoteInitialContextFactory");
        environment.put("java.naming.provider.url", "localhost:4201");

        try {
            InitialContext context = new InitialDirContext 
(environment);

            Object o = context.lookup("SampleBean");

but i got this exception :

javax.naming.AuthenticationException: Cannot read the response from  
the server (OEJP/2.0) : null; nested exception is:
    java.io.OptionalDataException
    at org.openejb.client.JNDIContext.authenticate(JNDIContext.java: 
196)
    at org.openejb.client.JNDIContext.getInitialContext 
(JNDIContext.java:181)


any idea ?
