JNDI Lookup fails in JBoss AS 7 [java.naming.CommunicationException]

created by Kousik Rajendran in JNDI and Naming - View the full discussion



I have successfully created and deployed a datasource in my jboss as 7. 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) {


I am getting this error

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.


Thanks in Advance. Please let me know if you need more information.
