JMS JNDI problems

[EcEiNeDnA]

Hi,


I am using Websphere Application Developer version 4.0.3 and MQ Series v5.3.

I am currently writing a normal java bean that send message to a Queue. Then i wrap the method sendMessage in my codes as a web service. When i use a test client to test run my web service i got the error as below:

Unable to obtain objects from JNDI
javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.jndi.fscontext.RefFSContextFactory. Root exception is java.lang.ClassNotFoundException: com.sun.jndi.fscontext.RefFSContextFactory

However, when i run my bean as a normal java application i did not encouner any problem. i have successfully inserted the message into the queue.

I have use Files system for binding. and Also i have included all the necessary .jars files: com.ibm.mq.jar,com.ibm.mqjms.jar,connector.jar,,fscontext.jar,providerutil.jar in my project.

and also added these jar into my classpath.
com.ibm.mq.jar,com.ibm.mqjms.jar,jms.jar,connector.jar,jndi.jar,ldap.jar,fscontext.jar,providerutil.jar.

Below are my codes....

import javax.naming.*;
import javax.jms.*;
import java.util.*;

public class QSender {

public static final String qcfLookup = &quot;MyQCF&quot;;
public static final String qInLookup = &quot;MyQueue&quot;;

static Queue requestQueue;
static QueueConnectionFactory factory;
static QueueConnection qCon;
static QueueSession qSession;

public void produceMessage(String text) {
try {
// use the file system JNDI context
Hashtable p = new Hashtable();
System.out.println(&quot;getting jndi context&quot;
p.put(Context.PROVIDER_URL, &quot;file://c|/Sample/MessageTut/temp&quot;
p.put(
Context.INITIAL_CONTEXT_FACTORY,
&quot;com.sun.jndi.fscontext.RefFSContextFactory&quot;

System.out.println(&quot;pass1&quot;
Context ctx = new InitialContext(p);
System.out.println(&quot;pass2&quot;

// Obtain the connection factory from JNDI
System.out.println(&quot;Retrieving JMS objects from JNDI&quot;
factory = (QueueConnectionFactory) ctx.lookup(qcfLookup);
System.out.println(&quot;pass3&quot;
requestQueue = (Queue) ctx.lookup(qInLookup);
System.out.println(&quot;pass4&quot;

} catch (NamingException e) {
System.err.println(&quot;Unable to obtain objects from JNDI&quot;
e.printStackTrace(System.err);
System.exit(0);
}

// Sending a message
try {
System.out.println(
&quot;sending message <&quot; + text + &quot;> to &quot; + requestQueue.getQueueName());
// get a connection and start it
QueueConnection qCon = factory.createQueueConnection();
qCon.start();
// Create a session from from the conection
qSession = qCon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
// Create a sender from the session
QueueSender qSender = qSession.createSender(requestQueue);
// Create a message to send to the queue...
TextMessage message = qSession.createTextMessage(text);
// ...now send the message
qSender.send(message);
System.out.println(&quot;message sent&quot;

} catch (JMSException e) {
System.out.println(&quot;Unable to send message&quot;
e.printStackTrace(System.err);
System.exit(0);

// always close the connection when done
} finally {
try {
if (qSession != null) {
qSession.close();
qSession = null;
}
if (qCon != null) {
qCon.close();
qCon = null;
}
} catch (JMSException e) {
System.out.println(&quot;Error closing connection&quot;
}
}
}

Could someone pls help me???
