"Failed to create session factory" from client connecting to jboss-as7 hornetq

lucapaone Oct 17, 2012 4:00 AM

Hi , I am trying to connect from a remote host to a Hornetq embedded in jboss as7. whith this code:

env.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName());

env.put(Context.PROVIDER_URL, "remote://192.168.81.17:4447");

env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

initialContext = new InitialContext(env);

ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("jms/RemoteConnectionFactory");

connection = cf.createConnection("guest", "guest");

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

But I receive this error

javax.jms.JMSException: Failed to create session factory

at org.hornetq.jms.client.HornetQConnectionFactory.createConnectionInternal(HornetQConnectionFactory.java:605)

ERROR RemoteNamingStoreV1 - Channel end notification received, closing channel Channel ID 96523c98 (outbound) of Remoting connection 26789869 to /192.168.242.128:4447

while on the server I can see:

09:21:39,566 INFO [org.jboss.as.naming] (Remoting "win-gv9pboi9ea1" task-1) JBA

From debug I can see that the exception is launched in the line:

connection = cf.createConnection("guest", "guest");

Can someone help us to find where we have an error?

first thing ive noticed is you are looking up the wrong jndi name for the connection factory, it should be 'java:jboss/exported/jms/RemoteConnectionFactory'. I would start by looking at one of the javaee examples in HornetQ master or one of the AS7 quick starts

I tried but now the app stops even the line before in

ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("java:jboss/exported/jms/RemoteConnectionFactory");

What is the reason?

Have you tried any of the examples or quickstarts?

Actually, you should be using "jms/RemoteConnectionFactory" just like the JMS quick-start. Based on the log on the server it looks to me like the JNDI lookup is succeeding. However, the fact that you're getting "Cannot connect to server(s). Tried with all available servers." tells me that perhaps your HornetQ connector is not configured correctly. Are you binding AS7 to 0.0.0.0?

No way , i tried all the suggested names.

I solved using instead of the JMS lookup

ConnectionFactory cf = (ConnectionFactory)
                 initialContext.lookup(connectionfactory);

the netty classes:

                Properties env = new Properties();
                // env.put(Context.INITIAL_CONTEXT_FACTORY,
                env.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName());
                env.put(Context.PROVIDER_URL, jndi_provider_url);
                env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
                initialContext = new InitialContext(env);
                HashMap map = new HashMap();
                map.put("host", netty_url);
                map.put("port", 5445);
                TransportConfiguration transportConfiguration = new TransportConfiguration("org.hornetq.core.remoting.impl.netty.NettyConnectorFactory", map);
                ConnectionFactory connectionFactory = (ConnectionFactory) HornetQJMSClient.createConnectionFactoryWithoutHA(JMSFactoryType.TOPIC_CF, transportConfiguration);
                connection = connectionFactory.createConnection();

AND ALL worked

This makes me think even more that the HornetQ connector(s) in your AS7 instance are not configured correctly. You see, when you do a JNDI look-up for a connection factory you download a connector which is basically just a simple stub which hold a bit of information (e.g. the host and port of the server) which the client then uses to connect to the server. If the connector isn't configured correctly on the server then even if the JNDI lookup succeeds when the client downloads the connector it will have problems connecting to the server (e.g. it will receive "Cannot connect to server(s). Tried with all available servers.").

If you're ok with just instantiating the connection factory via HornetQJMSClient.createConnectionFactoryWithoutHA() then you can remove all the code dealing with the InitialContext.

I tried to remove the initialcontext stuff but the code fails! It seems it is needed for some reasons....

In the first message I attached the jboss configuration (standalone-full.xml) we are using on the remote host. Could you try to see if therte is something wrong in the Hornetq configuration?

My guess is that you're still using JNDI to lookup the JMS destination.

In the first message I attached the jboss configuration (standalone-full.xml) we are using on the remote host. Could you try to see if therte is something wrong in the Hornetq configuration?
I looked at the standalone-full.xml you attached and I see a potential problem:

        <interface name="public">
            <inet-address value="${jboss.bind.address:0.0.0.0}"/>
        </interface>

If you are not explicitly setting the "jboss.bind.address" when the server boots (either via -Djboss.bind.address or -b) then it will bind to 0.0.0.0. I asked about this earlier and you said, "No way , i tried all the suggested names," although I'm not sure what you meant by that. If AS7 is binding to 0.0.0.0 then you will have problems as outlined in HORNETQ-952.

I think this is the problem!

Thank you so much!

(I was saying I tried all the jms/ConnectionFactort .. REmoteConnectionFActory ... etc)
