I am using JBoss-4.2.3.GA

The following files are used to get the JNDI context.

TestMain.java
------------------

public class TestMain {

private FluegeManager manager = null;
/**
* @param args
*/

public void testdatamethod() {
RemoteLocator remoteLocator = new RemoteLocator("org.jnp.interfaces.NamingContextFactory",
"jnp://localhost:8080",
"org.jboss.naming:org.jnp.interfaces");
manager = remoteLocator.getRemoteInstance(FluegeManager.class);
List fluegedata = manager.getAll();
System.out.println("Data Size is "+ fluegedata.size());

}
public static void main(String[] args) {
TestMain testMain = new TestMain();
testMain.testdatamethod();
}

}


RemoteLocater.java
---------------------------

public class RemoteLocator {
private JndiAccess jndiAccess;

public RemoteLocator() {
jndiAccess = new JndiAccess();
}

public RemoteLocator(String initialContextFactory, String providerUrl, String urlPkgPrefixes) {
jndiAccess = new JndiAccess(initialContextFactory, providerUrl, urlPkgPrefixes);
}

@SuppressWarnings({"MissingClassJavaDoc"})
public T getRemoteInstance(Class remoteInterface) {
return jndiAccess.lookup(remoteInterface.getSimpleName(), remoteInterface);
}
}

JndiAccess.java
---------------------

public class JndiAccess {
private String initialContextFactory;
private String providerUrl;
private String urlPkgPrefixes;
private InitialContext initialContext = null;

public JndiAccess() {
initialContextFactory = null;
providerUrl = null;
urlPkgPrefixes = null;
}

public JndiAccess(String initialContextFactory, String providerUrl, String urlPkgPrefixes) {
this.initialContextFactory = initialContextFactory;
this.providerUrl = providerUrl;
this.urlPkgPrefixes = urlPkgPrefixes;
}


private Object lookup(String dataJndiName) {
try {
if (initialContext == null) {
if (initialContextFactory != null || providerUrl != null || urlPkgPrefixes != null) {
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
env.put(Context.PROVIDER_URL, providerUrl);
env.put(Context.URL_PKG_PREFIXES, urlPkgPrefixes);
initialContext = new InitialContext(env);
} else {
initialContext = new InitialContext();
}
}
return initialContext.lookup(dataJndiName);
} catch (NamingException e) {
throw new SystemException("JNDI lookup for " + dataJndiName + " failed!", e);
}
}
}


Please help me.
