hi,
i am using jdeveloper for a project on jms and ejb. i created jms web service where i have mentioned my queueConnectionFactory as MyQueueConnectionFactory and queue as MyQueue. the web.xml file is also created which shows this. now i have written a small client code to send messages and message driven bean to receive messages. the code is written below:
package mypackage1;
import javax.jms.*;
import javax.naming.*;
import java.util.Hashtable;
import java.lang.Object;
import javax.rmi.PortableRemoteObject;
/**
* The SimpleClient class sends several messages
* to a queue.
*/
public class simpleClient
{
public simpleClient()
{
}
/**
* Main method.
*/
public static void main(String[] args)
{
Context jndiContext = null;
QueueConnectionFactory
queueConnectionFactory = null;
QueueConnection queueConnection = null;
QueueSession queueSession = null;
Queue queue = null;
QueueSender queueSender = null;
TextMessage message = null;
final int NUM_MSGS = 3;

/*
* Create a JNDI API InitialContext object.
*/
try
{
Hashtable env = new Hashtable();
env.put (Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://localhost:23893/current-workspace-app");
jndiContext = new InitialContext(env);
System.out.println("context: " + jndiContext);

}
catch (NamingException e)
{
System.out.println("Could not create JNDI API " +
"context: " + e.toString());
System.exit(1);
}

/*
* Look up connection factory and queue. If
either does not exist, exit.
*/
try
{
queueConnectionFactory = (QueueConnectionFactory)
PortableRemoteObject.narrow(jndiContext.lookup
("jms/MyQueueConnectionFactory"),QueueConnectionF actory.class);
System.out.println("found QCF ");
queue = (Queue)jndiContext.lookup("jms/MyQueue");
System.out.println("found Q");
}
catch (NamingException e)
{
System.out.println("JNDI API lookup failed: " +
e.toString());
System.exit(1);
}
/*
* Create connection.
* Create session from connection; false means
session is not transacted.
* Create sender and text message.
* Send messages, varying text slightly.
* Finally, close connection.
*/
try
{
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
message = queueSession.createTextMessage();
for (int i = 0; i (lessa than) NUM_MSGS; i++)//sorry for syntax error, this page was not excepting less than sign.
{
message.setText("This is message " + (i + 1));
System.out.println("Sending message: " +
message.getText());
queueSender.send(message);
}
}
catch (JMSException e)
{
System.out.println("Exception occurred: " +
e.toString());
}
finally
{
if (queueConnection != null)
{
try {
queueConnection.close();
}
catch (JMSException e) {}
}
System.exit(0);
}
}
}
while running this client code i get the following output:
context: javax.naming.InitialContext@4
JNDI API lookup failed: javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect; nested exception is:
java.net.ConnectException: Connection refused: connect
Process exited with exit code 1.
i tried both local and remote lookups to see if either works. but i m not able to find the error.
please let me know wht should i do to solve this problem.
thanks,
ashmi.
