How to close remote ejb/jndi connections

[michael_gronau]

Hello,

during my very somewhat painful journey to migrate our app to jboss7 (coming from 5.x) I found another little problem. What i want to achieve is like this:

1. create a normal jndi context (for non-ejb lookups) and an ejb context.

2. do somethings.

3. close the two connections.

4. do all this again and again.

My problem is I dont know how to close the connections. The only way I know, is close the jvm, but this is no solution for the described test case.

Imagine a remote web app that wants to call our app with hundreds or thousands of users (which is 2 connections per user in this test case). If a user signs off, we should be able to close the connection immediately.

With best regards

Michael

Hello, the following solution works for us:

InitialContext ctx = new InitialContext(remoteEjbProperties);
try {
   ...
   // do something with ctx, e.g. lookup & use EJBs via ejb: remote protocol
   ...
} finally {
   ctx.close();
}

But I see your requirement is different

It seems you want to have the control over the specific remoting connection, right?

How are you creating the EJB client context and registering the receivers?

Hi jaikiran,

I'm just doing it like this:

	this.ejbClientProperties.setProperty("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
	this.ejbClientProperties.setProperty("remote.connections", "default");
	this.ejbClientProperties.setProperty("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
//	this.ejbClientProperties.setProperty("remote.connection.default.connect.options.org.xnio.Options.SASL_MECHANISMS", "PLAIN");
	this.ejbClientProperties.setProperty("remote.connection.default.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS", "JBOSS-LOCAL-USER");
	this.ejbClientProperties.setProperty("remote.connection.default.host" , this.host);
	this.ejbClientProperties.setProperty("remote.connection.default.port", Integer.toString(this.port));
	this.ejbClientProperties.setProperty("callback.handler.class", AnonymousSaslClientCallbackHandler.class.getName());

	Hashtable jndiProperties = new Hashtable();
	jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

//

this.ejbNamingContext = new InitialContext(jndiProperties);

then i simply look up the ejb's via this.ejbNamingContext.lookup(...)

I debugged a little bit around and when i close the ejbNamingContext there is no special code executed to close the underlying connections, because the context is an instance of javax.naming.InitialContext, which does nearly nothing in its close() method.

Oh, and there is a little bit more:

after creating the ejb context with new InitialContext I create a new connection using the member variable this.ejbClientProperties like this:

new PropertiesBasedEJBClientConfiguration(this.ejbClientProperties);
