I tested with jboss CLI and I got the success message like [standalone@localhost:9999 /] /subsystem=datasources/data-source=java\:jboss\/datasources\/Test:test-connection-in-pool {     "outcome" => "success",     "result" => [true] } But, when I try to access the same data source using the java code DataSource ds = null; Context ctx = null; String strDSName = "java:jboss/datasources/Test"; try {     Properties env = new Properties();     env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");     env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");     env.setProperty("java.naming.provider.url", "jnp://localhost:1099");     ctx = new InitialContext(env);     ds = (javax.sql.DataSource) ctx.lookup(strDSName); } catch (Exception e) {     e.printStackTrace(); }   I am getting this error 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:392)           at c     om.aayuwiz.clinic.tests.KousikTests.main(KousikTests.java:42) 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 I have not done any changes to my *standalone.xml* under *\JBOSS_HOME\standalone\configuration* directory. Can someone help me out in this regards please. I have tried many forum threads and lot of blogs in and out of jboss.org sites. I am in a very critical situation to fix this issue ASAP.
