OK I will give a try. I think you have to define your QueueConnectionFactory
in your web.xml file in order. Is it the case? Look at the Servlet Spec for more info: http://jcp.org/aboutJava/communityprocess/first/jsr154/ Specifically in the DTD section. Also, maybe a j2ee related list might be the place to have a faster answer ;-) -- Jeanfrancois Ronald Haring wrote:
Hi all,
Using win2k, JDK1.3.1, J2ee1.3.1.
I have created a small JMS system to generate pdf files. I created a very
short test servlet.
In tomcat 3.2.3 my queue is found. In tomcat 4.0.4 and 4.1.12 I get the next
error:
NamingException
javax.naming.NameNotFoundException: Name QueueConnectionFactory is not bound
in
this Context

My code is :
protected void handle(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
try {
// Create the initial context
Context ctx = new InitialContext();
Hashtable env = ctx.getEnvironment();
Enumeration enum = env.keys();
while (enum.hasMoreElements()) {
String key = (String) enum.nextElement();
System.out.println(key + " = " + env.get(key));
}
QueueConnectionFactory queueConnectionFactory = null;
Queue queue = null;
try {
// The next definition works in tomcat 3.2.3
queueConnectionFactory = (QueueConnectionFactory)
ctx.lookup("QueueConnectionFactory");
queue = (Queue) ctx.lookup("generatePDF");
// The next definition doesnt work in either tomcat
//queueConnectionFactory = (QueueConnectionFactory)
ctx.lookup("java:comp/env/QueueConnectionFactory");
//queue = (Queue) ctx.lookup("java:comp/env/generatePDF");
System.out.println("Found the queue generatePDF");
}
catch (NamingException e) {
System.out.println("NamingException");
e.printStackTrace();
}
// Close the context when we're done
ctx.close();
}
catch (NamingException e) {
System.err.println("Problem " + e);
}
}
And here is my JmsDestination and JmsFactory listing:
D:\jakarta-tomcat-4.0.4\bin>j2eeadmin -listJmsDestination
JmsDestination
--------------
< JMS Destination : sendPDF , javax.jms.Queue >
< JMS Destination : jms/Topic , javax.jms.Topic >
< JMS Destination : jms/Queue , javax.jms.Queue >
< JMS Destination : generatePDF , javax.jms.Queue >
D:\jakarta-tomcat-4.0.4\bin>j2eeadmin -listJmsFactory
JmsFactory
----------
< JMS Cnx Factory : QueueConnectionFactory , Queue , No properties >
< JMS Cnx Factory : jms/TopicConnectionFactory , Topic , No properties >
< JMS Cnx Factory : TopicConnectionFactory , Topic , No properties >
< JMS Cnx Factory : jms/QueueConnectionFactory , Queue , No properties >
D:\jakarta-tomcat-4.0.4\bin>
After running the servlet on 3.2.3 I get 2 errors for loading ejb and
security.properties file, but after that it prints the following for the
enumeration
on the context:
java.naming.corba.orb = com.sun.enterprise.iiop.POAEJBORB@a49e0
and for tomcat 4.0.4
java.naming.factory.initial = org.apache.naming.java.javaURLContextFactory
java.naming.factory.url.pkgs = org.apache.naming:com.sun.enterprise.naming
So here is a big difference. The one from 3.2.3 appears to be an instance of
a class
whereas the ones from 4.0.4 are just string representations of classes to
load.
Now how can I activate my Jms system, in order for Tomcat 4.0.4 to find it?
Or what should I do so Tomcat will be able to find my queues and use them?
