Properties props = new Properties();

props.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");

props.put(Context.PROVIDER_URL,"172.25.8.195:50004");

Context con = new InitialContext(props);

Object obj = con.lookup("MESSAGEJNDI");

MessageGetHome mhome = (MessageGetHome)PortableRemoteObject.narrow(obj,MessageGetHome.class);

MessageGet bean = (MessageGet)mhome.create();

Hi brahm,

1) try to specify

Context.SECURITY_PRINCIPAL with username and

Context.SECURITY_CREDENTIALS with password

2) to check JNDI name of EJB go to Visual Administrator->Services->EJB Container, choose your EJB and check "JNDI name" property.

Hi brahm,

Yes, you are right. It is user name and password from UME on WAS. Same as you use to login to WD application.

Hi Brahmanandam,

Check username/password and hostname/port for P4 service (you can check it in Visual Administrator - it appears by logging in) and check this http://help.sap.com/saphelp_nw04/helpdata/en/a2/f9d7fed2adc340ab462ae159d19509/frameset.htm . May be you have more than one instance on your server. For me, port is for example - 50204. The rest seems to be OK. Could you post the whole stacktrace of exception?

Best regards, Maksim Rashchynski.

hello Maksim ,

i am getting the following exception trace,

can u please look into it and tell me what could be the problem.

com.sap.engine.services.jndi.persistent.exceptions.NoPermissionException: Exception during getInitialContext operation. Wrong security principle/credentials. [Root exception is com.sap.engine.services.security.exceptions.BaseLoginException: User not authorized.]

please suggest solution for it.

thank you,

Hi Brahmanandam,

Seems like your user is not authorized to call EJB, or username and/or password are not correct.

Hi,

I am facing the same problem, I am able to look ejb locally on same server, but remotely it is not working.

here is the sample code!

env.put(Context.PROVIDER_URL, "10.48.121.207:53004"); //p4 port

// env.put("force_remote", "true");

env.put(Context.SECURITY_PRINCIPAL, "Administrator");

env.put(Context.SECURITY_CREDENTIALS, "sapxxx");

InitialContext ctx = new InitialContext(env);

//Object obj = ctx.lookup("RiskAnalysis");

Object obj = ctx.lookup("java:comp/env/ejb/RiskAnalysisBean");

Please advise, what could be the problem, I did all possible things, adding ejb-ref and updating the .xml files with required ref attributes on both EJB and client applications, but still remote lookup is failing!

Please send me sample working ejb and client example for remote lookup, I am working on NW700 with sp12.

Thanks for your information,

Anil
