SLSB EJB3.1 invocation server to server - localhost and remote host

maderhan Dec 11, 2012 5:01 AM

Hi,

I have two servers and one SFSB ejbX inside a WAR:

hostA

|---------webApp1 (war)

|---------webApp2 (war)

|---------ejbX

hostB

|---------webApp2 (war)

|---------ejbX

The approach is: Sequential method call on both ejbs

1) webApp1 method call to webApp2/ejbX on hostA -> same host

2) webApp1 method call to webApp2/ejbX on hostB -> remote host

Step 1 is working fine!

Step 2 throws an Exception when I try to instanciate a new InitialContext.

Here is my Code (inside from a WAR context):

String serverUrl="remote://localhost:port";

final Properties jndiProps = new Properties();

            if ( serverUrl.trim().toLowerCase().indexOf("localhost")==-1 ){
                jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
            }

            jndiProps.put("jboss.naming.client.ejb.context", true);
            jndiProps.put(Context.PROVIDER_URL, serverUrl);
            jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

jndiProps.put(Context.SECURITY_PRINCIPAL, "xxxxx");
jndiProps.put(Context.SECURITY_CREDENTIALS, "xxxxxx");

InitialContext context = new InitialContext(jndiProps);

EjbXRemote ejbX = c.lookup("ejb:/myApp/ejbX!EjbXRemote");

ejbX.methodCall(); // OK

serverUrl="remote://hostB:port";

final Properties jndiPropsB = new Properties();

            if ( serverUrl.trim().toLowerCase().indexOf("localhost")==-1 ){
                jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
            }

            jndiPropsB.put("jboss.naming.client.ejb.context", true);
            jndiPropsB.put(Context.PROVIDER_URL, serverUrl);
            jndiPropsB.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

jndiPropsB.put(Context.SECURITY_PRINCIPAL, "xxxxx");
jndiPropsB.put(Context.SECURITY_CREDENTIALS, "xxxxxx");

InitialContext context = new InitialContext(jndiPropsB); // Exception

EjbXRemote ejbX = c.lookup("ejb:/myApp/ejbX!EjbXRemote");

ejbX.methodCall();

Exception:
