I went through the following link for how to use Jboss for JMS http://docs.jboss.org/jbossmessaging/docs/usermanual-2.0.0.beta1/html/usi... I am getting an exception while looking up for ConnectionFactory (http://docs.oracle.com/javaee/6/api/javax/jms/ConnectionFactory.html) i.e. "iniCtx.lookup("ConnectionFactory")" javax.naming.CommunicationException (http://docs.oracle.com/javase/7/docs/api/javax/naming/CommunicationExcept...): Receive timed out [Root exception is java.net.SocketTimeoutException (http://docs.oracle.com/javase/7/docs/api/java/net/SocketTimeoutException....): Receive timed out]      at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1058)      at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1127)      at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:478)      at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:471)      at javax.naming.InitialContext.lookup(Unknown Source)      at MessageProducer.main(MessageProducer.java:46) Caused by: java.net.SocketTimeoutException (http://docs.oracle.com/javase/7/docs/api/java/net/SocketTimeoutException....): Receive timed out      at java.net.PlainDatagramSocketImpl.receive0(Native Method)      at java.net.PlainDatagramSocketImpl.receive(Unknown Source)      at java.net.DatagramSocket.receive(Unknown Source)      at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1038) The reason is, Jboss Naming Service is not running(netstat -an doesn't show any result for port 1099) .   I didn't configure any specific setting for Naming Service. I let it to take default port 1099. Am I missing any configuration? Kindly help me in running the Jboss naming service.
