HI, i am developing a client application to implement JBossMQ JMS. i also have jboss4.2 on my system. IN my client application i have included all the jars necessary. I can run the application and get desired results whn JBoss app server is running.But when i shut the JBoss application server i get the following error Exception in thread "main" javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1302) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1382) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:579) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:572) at javax.naming.InitialContext.lookup(InitialContext.java:351) at src.Client.main(Client.java:30) Caused by: java.net.SocketTimeoutException: Receive timed out at java.net.PlainDatagramSocketImpl.receive0(Native Method) at java.net.PlainDatagramSocketImpl.receive(PlainDatagramSocketImpl.java:136) at java.net.DatagramSocket.receive(DatagramSocket.java:712) at org.jnp.interfaces.NamingContext.discoverServer(NamingContext.java:1272) ... 5 more Does it mean running JBoss app server is mandatory.Is there any other way where i can do my example without running jboss App server or running only JBoss MQ feature of Jboss (not whole app server).
