Can u Help me, how to solved this message bean, Error?
Hi All,
I am new bie for this J2EE. How can i solved this.. always javax.naming.NameNot FoundException but i 've already done to put in jndi name in the ejb.xml descriptor .
try
{
connectionfactory = (ConnectionFactory)jndiContext.lookup("jms/SimpleMessageDestinationFactory");
destination = (Queue)jndiContext.lookup("jms/SimpleMessageBean");
}catch(NamingException e){
System.err.println("Jndi lookup failed:" + e.toString());
System.exit(1);
}
try{
connection = connectionfactory.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
messageProducer = session.createProducer(destination);
Error for compilation.
init:
deps-jar:
compile-single:
run-single:
Jndi lookup failed:javax.naming.NameNotFoundException: SimpleMessageDestinationFactory not found
Java Result: 1
BUILD SUCCESSFUL (total time: 5 seconds)
Thanks for your reply..

CJ,
Do you mean ejb-jar.xml? The portable way to lookup this kind of resource dependency in Java EE
is to define an @Resource annotation or a resource-ref in ejb-jar.xml.The res-ref-name element
of resource-ref corresponds to the private component naming environment of the component.
Your code snippet does not show how the jndiContext was instantiated but the code
should look like this :
InitialContext ic = new InitialContext();
destination = (ConnectionFactory) ic.lookup("java:comp/env/jms/SimpleMessageDestinationFactory");
In this case, the name of the dependency within your component environment(res-ref-name) must be
"jms/SimpleMessageDestinationFactory".Note that this is not the same thing as the
global JNDI name of the Connection Factory.
If you're defining a Queue dependency in the descriptor, use a resource-env-ref instead.

This is an xml based for ejb.xml descriptor

Thanks ken for reply.

Are you trying to connect from a stand-alone client? In this case, you must include for the client several jars that you will find in lib server directory
sun/sdk/lib/javaee.jar
sun/sdk/lib/j2ee.jar
sun/sdk/lib/appserv-rt.jar
sun/sdk/lib/appserv-admin.jar
sun/sdk/lib/appserv-ws.jar
And moreover you must include the next. I show separately because at the beggining I didn磘 know and jms fails me.
sun/sdk/lib/install/applications/jmsra/imqjmsra.jar
I hope it helps you.
Hayken.
