You can find below my class
:
package
test4;
import
java.util.Hashtable;
import java.util.Map;
import
java.util.Properties;
import javax.jms.Connection;
import
javax.jms.Queue;
import javax.jms.ConnectionFactory;
import
javax.jms.JMSContext;
import
javax.jms.JMSException;
import
javax.jms.JMSProducer;
import javax.jms.QueueConnection;
import
javax.jms.QueueConnectionFactory;
import
javax.naming.Context;
import javax.naming.InitialContext;
import
javax.naming.NamingException;
/**

*/
public class Test4
{
/**
* @param args the command line
arguments
*/
public static void main(String[] args) throws
NamingException {
Context initialContext =
Test4.getInitialContext();
ConnectionFactory
connectionFactory =
(ConnectionFactory)initialContext.lookup("jms/connection");
JMSContext jMSContext = connectionFactory.createContext();
Queue myQueue =
(Queue)initialContext.lookup("jms/myQueue");
JMSProducer jMSProducer =
jMSContext.createProducer();
jMSProducer.send(myQueue, "Hi,Zion");
System.out.println("work work work wrok
wrok");
}
public static
Context getInitialContext() throws NamingException{
Hashtable env = new
Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.enterprise.naming.impl.SerialInitContextFactory");
env.put(Context.STATE_FACTORIES,
"com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
env.put(Context.URL_PKG_PREFIXES, "com.sun.enterprise.naming");
env.put("org.omg.CORBA.ORBInitialHost", "IP");
env.put("org.omg.CORBA.ORBInitialPort", "Port");
return new
InitialContext(env);
}
}
Inside
the folder
:
/opt/Tests/Test4/src/test4#
ls
Test4.class
Test4.java
You need
to include your Test4 class file to the classpath.
Assuming your Test4.class file is located on
/opt/Tests/Test4/src/test4
and the fully qualified name is
test4.Test4 then you should do something
like:
/opt/Tests/Test4/src> java
-cp "/opt/glassfish5/glassfish/lib/*":"."
test4.Test4
Note that the directory
of the terminal is /opt/Tests/Test4/src and not
/opt/Tests/Test4/src/test4
Hope this
helps
