Hi,

I am trying to get a JNDI Context to a JBoss 3.0.8 (Jetty) instance from a separate instance of Tomcat 4.1.27 (both running on the same machine). The following code works fine from a stand-alone jar file (with the following jars added to the class path: xercesImpl.jar, xmlParserAPIs.jar, jboss-client.jar, jboss-common-client.jar, jboss-j2ee.jar, jbosssx-client.jar, jnp-client.jar, log4j.jar). However, when I envoke the Lookup.test() method from a servlet I get a naming exception whose getMessage() method returns null. Any ideas why? (Yes, 1098 is correct, I tried using 1099 in the code and the JBoss instance with the same result).

public class Lookup {

public InitialContext getInitialContext() throws NamingException {
Hashtable props = new Hashtable();
InitialContext initial = null;

props.put(
Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");

props.put(Context.PROVIDER_URL, "jnp://localhost:1098");

props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

initial = new InitialContext(props);

return (initial);
}

public String test() {
BillsServiceHome billsServiceHome = null;
BillsService service = null;
InitialContext initial = null;
Collection results = null;
Object[] array = null;
StringBuffer result = new StringBuffer();

try {
initial = getInitialContext();

// Locate the home interfaces.
billsServiceHome =
(BillsServiceHome) initial.lookup("BillsService");

service = billsServiceHome.create();

// Retrieve the list of bills.
results = service.getUserList();

array = results.toArray();

for (int i = 0; i < array.length; i++) {
result.append(array);
}

} catch (NamingException ne) {
System.out.println("Lookup: NamingException\n" + ne.getMessage());
} catch (RemoteException re) {
System.out.println("Lookup: \n" + re.getMessage());
} catch (CreateException ce) {
System.out.println("Lookup: \n" + ce.getMessage());
}

return (result.toString());
}

public static void main(String[] args) {
String data = null;
Lookup lookup = new Lookup();

data = lookup.test();

System.out.println(data);
}
