Unable to do a simple remote EJB lookup.

[blakecmartin]

I'm trying to look up an EJB on a remote server from a Java application on my local machine. I've set up an application user in WildFly 8.0.0 and am running in standalone-full mode. The EJB deployed successfully.

When I try to look up the EJB using the following code (which I'm sure is wrong due to the JNDI name), I get the following error:

• ERROR: JBREM000200: Remote connection failed: javax.security.sasl.SaslException: Authentication failed: the server presented no authentication mechanisms

Any idea as to what the problem could be?

Thanks,

Blake

	String host = "172.16.18.39";
	Properties clientProperties = new Properties();
	clientProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
	clientProperties.put(Context.PROVIDER_URL, "http-remoting://" + host + ":8080");
	clientProperties.put(Context.SECURITY_PRINCIPAL, "abc");
	clientProperties.put(Context.SECURITY_CREDENTIALS, "123");
	clientProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
	clientProperties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
	clientProperties.put("remote.connections", "default");
	clientProperties.put("remote.connection.default.port", 8080);
	clientProperties.put("remote.connection.default.host", host);
	clientProperties.put("remote.connection.default.username", "abc");
	clientProperties.put("remote.connection.default.password", "123");

	EJBClientConfiguration ejbClientConfiguration = new PropertiesBasedEJBClientConfiguration(clientProperties);
	ContextSelector<EJBClientContext> contextSelector = new ConfigBasedEJBClientContextSelector(ejbClientConfiguration);
	EJBClientContext.setSelector(contextSelector);

	Context context = new InitialContext(clientProperties);
	context.lookup("java:global/ejb-ear-1.0/an-ejb-1.0/SomeEjb!com.xyz.ejb.SomeEjbRemote");

I suppose the JNDI name should be "ejb:ejb-ear-1.0/an-ejb-1.0/SomeEjb!com.xyz.ejb.SomeEjbRemote"

Also the properties are a mix of remote-naming and ejb-client, this mix will have unexpected results.

Please look to the ejb-remote example and documentation EJB invocations from a remote client using JNDI

Thank you for letting me know the proper JNDI name (and that the prefix has changed to "ejb:"). I made those changes.

Now I'm getting that error plus a new one:

• WARN: Could not register a EJB receiver for connection to 172.16.18.39:8080
• ERROR: JBREM000200: Remote connection failed: javax.security.sasl.SaslException: Authentication failed: the server presented no authentication mechanisms
• Exception in thread "main" java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:ejb-ear-1.0, moduleName:an-ejb-1.0, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@aee25db

I based the JNDI name on the URI I found in the server log. I'm attempting to look up this: "ejb:ejb-ear-1.0/an-ejb-1.0/SomeEjb!" + SomeEjbRemote.class.getName()

Did you remove the security-realm from the connector?

Maybe you should have a look to the ejb-remote quickstart which might give you hints
