Creating multiple instance of one EJB-Class causes "No EJB receiver available"-Exception

[goot]

I have a Tomcat running on the frontend side while my EJBs are running on a JBoss AS 7.1

My (stateful) EJB Class is not annotated as a singleton.

Anyway, when I try to lookup two EJBs at the same time, I receive an exception message about a missing EJB receiver.

I need to provide this EJB for dozens of users at the same time.

When I restart the Tomcat user, I can call the EJBs again, maybe this happens because the ejb-user is already logged in to the JBoss?

Is there anything I can do to avoid this error?

Not sure what you try to achieve.

Do you need to connect with different user credentials?

When the problem happen?

Could you show the relevant lookup and invocation code?

[goot]

I added the lookup source to my post.

The problem happens when I try to lookup for more than one time, no matter if I created a new session on the  frontend side or not.

[jaikiran]

Please upgrade to a later  version of JBoss AS/WildFly Downloads There have been numerous fixes after 7.1.1.Final.

[wdfink]

The IC and Selector creation for lookup is a mix of remote-naming and ejb-client.

You should read the ejb-client and the remote-naming section of the documentation and use one of it, I recommend to use the ejb-client approach as remote-naming does not support all features. I suppose if you use the jboss-ejb-client.properties file it might work, but you are not able to set the properties programatic.

Nevertheless whether it work or not you should upgrade to a newer version as Jaikiran already mentioned. Also you have a new feature to connect, see scoped-context documentation

[goot]

I removed the selector part from the lookup and I updated to WildFly 8.0 Alpha 4

According to

http://jaitechwriteups.blogspot.de/2013/07/wildfly-800alpha3-released-with-support.html

JNDI Lookup Failing

I edited my lookup code and set the provider url to "http-remoting://localhost:8080". Also I added the new jboss-client.jar to my classpath.

When I try to lookup this will return a message about the missing http-remoting scheme.

What am I missing here?

[jaikiran]

The line numbers of remote-naming project doesn't match with the latest libraries. So I think you have a mismatch with the library versions on the client side. How are you managing the library versions on the client classpath?

Other than fixing the classpath, all you need is making sure the code is right. It should be something like this like explained in the documentation here https://docs.jboss.org/author/display/WFLY8/Scoped+EJB+client+contexts

final Properties jndiProps = new Properties();
        // Property to enable scoped EJB client context which will be tied to the JNDI context
        jndiProps.put("org.jboss.ejb.client.scoped.context", true);
        // Property which will handle the ejb: namespace during JNDI lookup
        jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

        final String connectionName = "foo-bar-connection";
        jndiProps.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
        // add a property which lists the connections that we are configuring. In
        // this example, we are just configuring a single connection named "foo-bar-connection"
        jndiProps.put("remote.connections", connectionName);
        // add a property which points to the host server of the "foo-bar-connection"
        jndiProps.put("remote.connection." + connectionName + ".host", "localhost");
        // add a property which points to the port on which the server is listening for EJB invocations
        jndiProps.put("remote.connection." + connectionName + ".port", "8080");
        // add the username and password properties which will be used to establish this connection
        jndiProps.put("remote.connection." + connectionName + ".username", "username");
        jndiProps.put("remote.connection." + connectionName + ".password", "password");


        Context ejbJNDIContext = new InitialContext(jndiProps).lookup("ejb:"); 
        try {
            System.out.println("Looking EJB via JNDI "); 
            String typeOfEJB = "stateful"; 
            remote = (LoginBeanRemote) context.lookup("foo_business_ear-ear/foo_business_ear-ejb//LoginBean!foo.business.login.LoginBeanRemote" + "?" + typeOfEJB); 
            System.out.println(remote.helloBean()); 
        } finally {
            ejbJNDIContext.close();
        }
