Unable to connect Remote JMS client while trying to connect with Standalone hornetq server (with bind address as 0.0.0.0)

[ajinkya.bambal]

I have standalone HornetQ server (2.3.0.Final) running in non-clustered mode . I  have added bind address and connector/acceptor host as 0.0.0.0 in hornetq-beans.xml and hornetq-configuration.xml . The machine where hornetq deployed has two interfaces with IP address as 192.168.75.206 , 192.168.75.208 .

        When any JMS client tries to connect with HQ server (with lookup address as 192.168.75.206) ,  it is getting connected successfully if both JMS client and server are on same physical machine. But  if JMS client is running at remote machine (192.168.75.212) and tries to connect with HornetQ server (with lookup address as 192.168.75.206) , following exception is coming at JMS client side ,

I think you can't use 0.0.0.0 at client side, you need to tell client which IP to use to connect to. The server can bind to 0.0.0.0 however.

Hi Yong ,

Thanks for the quick answer . But I am not using 0.0.0.0 from JMS client side for look up . I am using proper address for look up (192.168.75.206) . But JMS client is  still failing to connect  if JMS client is at remote machine.

Ah Ok, I thought you were using the ConnectionFactory which uses netty-throughput connector. Can you show me what your client code looks like? espeically how to estabilish the connection against the servers?

[ajinkya.bambal]

I have attached  the JMS client code alonwith Hornetq server conf in the main thread .  PFA for the same  and let me know if you need any inputs from my side .

Thanks. I can see you use jndi lookup to find a connection factory:

cf = (javax.jms.QueueConnectionFactory)ic.lookup("/ConnectionFactory");

which you will get one that uses connector "netty" as shown in your hornetq-jms.xml. The netty connector is configured as this:

      <connector name="netty">

        <factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>

        <param key="host"  value="${hornetq.remoting.netty.host:0.0.0.0}"/>

        <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>

      </connector>

So your client will use 0.0.0.0 as host to connect to. I'd suggest you add a specific connector to point to a specific IP of your nodes.

Since I have added 0.0.0.0 as a acceptor host , JMS client should connect to either one of the interface IP automatically without explicitely mentioning connector host IP .

I don't think this could work at client side. How can a remote client know the address of your servers given only 0.0.0.0? If you like your client to work with multiple servers transparently I suggest you use discovery group which uses UDP (or jgroups) broadcasting to find the server.
