If anyone can provide some insight into why this isnt working that would be great! I used JMSAdmin on my WinNT machine to load up the jndi names:
def ctx(ehub)
chg ctx(ehub)
def qcf(QCF) qmgr(TCK6) +
tran(client) chan(TCK6.TO.CLIENTS) +
host(rs111) port(1414)
def q(Q) qmgr(TCK6) queue(EHT.TDSIREQUEST)
end
So i run my program's main method through WSAD, and it gives me the following error:
{java.naming.provider.url=file:/c:/errors, java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory}
javax.naming.NameNotFoundException: ehub/QCF

Connection setting error: javax.naming.NameNotFoundException: ehub/QCF |

Are you sure you have .binding in c:\errors path as declared ?
Another consideration, if you created it with right values on the firt time or not ?
Because JMSAdmin configuration utility appends this file.

Yes, i deleted the c:/errors/ehub directory, then ran the jmsadmin program again to readd that directory with the .bindings file.
Is there any other program I need running? I am running my MQReceiver program out of WSAD. I had it running just fine with an IBM example using iiop, but would rather use the file system jndi. |

I thought that you had to put a '/' on the front of the ehub:
/ehub/QCF
Did you try this? |

yes ive tried that. Heres the code im using:
public class getMQMessage2 extends Thread implements MessageListener {
private static final String INITIAL_CONTEXT_FACTORY_PROP = "initialContextFactory";
private static final String INITIAL_CONTEXT_FACTORY = "java.naming.factory.initial";
private static final String PROVIDER_URL = "file://c:/errors";
private QueueConnection connection;
private QueueSession session;
private QueueReceiver receiver;
private InitialContext initContext;
private String initialContextFactory;
private String exceptionMessage;
private String message;
private static getMQMessage2 ivjReceiver = null;
public static void main(String argv[]) {
ivjReceiver = new getMQMessage2();
InputStreamReader userInput = new InputStreamReader(System.in);
try {
ivjReceiver.setConnection("/ehub/QCF");
ivjReceiver.setQueue("/ehub/Q");
} catch (java.lang.Throwable ex) {
System.out.println("Connection setting error: " + ex);
System.exit(0);
}
char answer = '\0';
System.out.println("To stop receiver, enter Q and <return>");
while (!((answer == 'q') || (answer == 'Q'))) {
try {
answer = (char) userInput.read();
} catch (IOException iex) {
}
}
}
public void close() throws JMSException, NamingException, Throwable {
try {
System.out.println("Closing connection");
if (connection != null)
connection.stop();
if (receiver != null)
receiver.close();
if (session != null)
session.close();
if (connection != null)
connection.close();
if (initContext != null)
initContext.close();
} catch (Throwable e) {
setExceptionMessage(e);
throw e;
}
}
public String getExceptionMessage() {
return exceptionMessage;
}
public String getMessage() {
return message;
}
private InitialContext getInitContext() throws NamingException {
if (initContext == null) {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, getInitialContextFactory());
properties.put(Context.PROVIDER_URL, PROVIDER_URL);
// System.out.println(properties.toString());
initContext = new InitialContext(properties);
// System.out.println(initContext.toString());
}
return initContext;
}
private String getInitialContextFactory() {
if (initialContextFactory == null) {
initialContextFactory = System.getProperty(INITIAL_CONTEXT_FACTORY_PROP);
}
return initialContextFactory;
}
public void onMessage(Message message) {
String msgText = null;
try {
msgText = ((TextMessage) message).getText();
System.out.println(msgText);
if (msgText.substring(0, 3).equals("$*$")) {
System.out.println("A server message was received");
} else
SendRequestToFord2.SendRequest(msgText);
} catch (Throwable e) {
setExceptionMessage(e);
msgText = getExceptionMessage();
}
}
public void setConnection(String connectionName)
throws JMSException, NamingException, Throwable {
try {
close();
QueueConnectionFactory factory =
(QueueConnectionFactory) getInitContext().lookup(connectionName);
System.out.println("After setting QCF");
connection = factory.createQueueConnection();
System.out.println("After creating Queue Connection");
session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
System.out.println("After creating Queue Session");
} catch (Throwable e) {
setExceptionMessage(e);
e.printStackTrace();
sleep(1000);
throw e;
}
}
private void setExceptionMessage(Throwable t) {
exceptionMessage = "Exception: " + t.toString();
}
public void setQueue(String queueName)
throws JMSException, NamingException, Throwable {
try {
if (connection != null)
connection.stop();
if (receiver != null)
receiver.close();
Queue queue = (Queue) getInitContext().lookup(queueName);
receiver = session.createReceiver(queue);
receiver.setMessageListener(this);
connection.start();
} catch (Throwable e) {
setExceptionMessage(e);
throw e;
}
}

i figured out a solution:
private static final String PROVIDER_URL = "file://c:/errors/ehub";
and then having the queueconnectionfactory as "QCF"
and the queue name as "Q"
Any ideas why setting the intial url as c:/errors did not work? But changing it to c:/errors/ehub did work? |

Hi
IBM's documentation in this regard is scant.
From http://www7b.software.ibm.com/wsdd/techjournal/0204_minocha/minocha.html:
'On the other hand, the file system JNDI service has trouble resolving names qualified by subcontexts. For example, name "Sample/JMS/Q1" refers to object Q1 in subcontext JMS of subcontext Sample. Looking up "Sample/JMS/Q1" works in Application Server, but you may have to flatten the name, for example to "JMSQ1," for the file system.'
Cheers
Justin |
