Problem in Accessing the EJB

Posted on Jan 18, 2005 at 11:46 AM 5 Views

I want to access remote EJB from my Portal Service.

the EJB and the portal Service run on a separated machines.

here is what i wrote:

Properties properties = new Properties();

properties.put(Context.INITIAL_CONTEXT_FACTORY,

"com.sap.engine.services.jndi.InitialContextFactoryImpl");

properties.put(Context.PROVIDER_URL, "p030633:50004");

InitialContext context = new InitialContext(properties);

String name = "sap.com/GDS/GtinManager";

GtinManagerHome home = (GtinManagerHome)

javax.rmi.PortableRemoteObject.narrow.narrow(

context.lookup(name), GtinManagerHome.class);

gm = (GtinManager)home.create();

i run this code from java application and it works.

but in portal i get this error:

"com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at GDS, the whole lookup name is sap.com/GDS/GtinManager."

Thanks

    Hello,

    if you NW 04 SP7 or higher, please look this document

    https://www.sdn.sap.com/sdn/index.sdn?contenttype=url&content=/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/how to access an ejb from a portal component.mht

    else in EP6 SP2, it is more difficult to access to an EJB because the portal have an other classloader sysem and other JNDI context

    Best Regards,

    Fabrice

    He,

    maybe it's just this line missing:

    properties.put(“force_remote”, “true”);
