Great thanks!

By following the updated document, I succeeded to use remote EJB connection with authentication.

That's good to know! Thanks for trying it out.

Great work Jaikiran - it's a milestone for me to get this going properly.

Thanks Etsuji - your post is helpful to know what remining changes were required to get there via the discussion above.

recoverability

Jaikiran, I did notice however that the "client" server does not recover it's connection upon the remote ejb server's restart. Is this a known issue?

This is the error I get on the "client" server despite doing a fresh JNDI lookup of the remote EJB:

java.lang.IllegalStateException: No EJB receiver available for handling [appName:MyAppCostingEngine,modulename:CostingEngine,distinctname:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@781f36

The problem persists until each "client" server is restarted.

That was a bug which was fixed just yesterday https://community.jboss.org/message/730057#730057. Please try the latest nightly build which has this fix https://community.jboss.org/thread/167590

Jaikiran, that looks much better (remote ejb recoverability).

I get:

Then the subsequent request succeeds.

tested in

Thanks for verifying that.

From client code in Developer guide, it assumes there is only one single remoting-ejb-receiver defined in jboss-ejb-client.xml, what if I need to programmaticall invoke different server instances ? Is there any sample for this ?

            final Hashtable props = new Hashtable();

            // setup the ejb: namespace URL factory

            props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

            // create the InitialContext

            final Context context = new javax.naming.InitialContext(props);

Hello, can someone help me please, am very confused.

I try to migrate ùy application from jboss as 5 to jboss as 7.1.1.final

How i can lookup local ejb in ear :

- ear

    - jar

    -sar

i want to call local ejb in my jar from class in my sar project;

i have added jboss-ejb-cleint.properties like this :

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

remote.connections=default

remote.connection.default.host=localhost

remote.connection.default.port = 4447

remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

gettting the context :

private Context getInitialContext() throws NamingException {

        if (initialContext == null) {

            Properties properties = new Properties();

            properties.put(Context.URL_PKG_PREFIXES, PKG_INTERFACES);

            //properties.put("jboss.naming.client.ejb.context", true);

            initialContext = new InitialContext(properties);

        }

        return initialContext;

    }

if a lookup object i have an result : class com.sun.proxy.$Proxy16 (system.out)

AND if i try to call an method :

Hello.

Thanks for this Tutorial.

But what about communication between several JBoss instances, on several IPs... ?

How to get this done if the architecture is composed of a certain amount of JBoss servers talking to each other through EJB calls ?

Is there a way to set this config in the code?

Thank you.
