Description
I am not create a jndi connection from my java program despite specifying all the connection parameters in the jndi.properties and activemq.xml:
I have done the configuration of jndi.properties file as follows:
java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
java.naming.provider.url=tcp://localhost:61616
java.naming.security.principal=system
java.naming.security.credentials=manager
- use the following property to configure the default connector
java.naming.provider.url = vm://localhost
#connectionFactoryNames = TopicCF
#topic.topic1 = jms.topic1
connectionFactoryNames = QueueCF
queue.LoanRequestQ = jms.LoanRequestQ
queue.LoanResponseQ = jms.LoanResponseQ
Added the following in activemq.xml:
<destinations>
<! – topic name="topic1" physicalName="jms.topic1" / -->
<queue name="LoanRequestQ" physicalName="jms.LoanRequestQ" />
<queue name="LoanResponseQ" physicalName="jms.LoanResponseQ" />
</destinations>
Now, in my Java program, I have the QLender class and I have the following statements:
Context ctx = new InitialContext();
ConnectionFactory qCFactory = (ConnectionFactory)ctx.lookup("QueueCF");
I get the following error:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

at ch04.p2p.QLender.<init>(QLender.java:34)
at ch04.p2p.QLender.main(QLender.java:134)
Further I enhanced the program to make a set environment parameters:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.activemq.jndi.ActiveMQInitialContextFactory");
env.put(Context.PROVIDER_URL, "http://localhost:61616");
env.put(Context.SECURITY_PRINCIPAL, "system");
env.put(Context.SECURITY_CREDENTIALS, "manager");
Context ctx = new InitialContext(env);
ConnectionFactory qCFactory = (ConnectionFactory)ctx.lookup("QueueCF");
On compiling I get the following error:
javax.naming.NameNotFoundException: QueueCF
