I am trying to create a connection using connectionFactory.createConnection() method but it returns a null.
Below is my code :
@Stateless
public class test
{
@Resource(mappedName = "java:comp/DefaultJMSConnectionFactory")
private static ConnectionFactory connectionFactory;
@Resource(mappedName = "jdbc/JurassicParkCon")
private static Queue queue;
public static void main(String args[])
{
Connection connection = null;
Session session = null;
MessageProducer messageProducer = null;
TextMessage message = null;
final int NUM_MSGS = 3;
try {
connection = connectionFactory.createConnection();
}
catch(Exception e){System.out.println("It is:"+e.getMessage());}
In the above code am only trying to create a connection but it returns NullPointerException. I have added a JMS resource through the admin console in GlassFish (name is jdbc/JurassicParkCon).
Recently only I started working with EJB's so I am not very familiar with errors. I have added the @Stateless annotation because there was a similar problem which was posted on StackOverflow and for that user adding the annotation worked but not for me.
What might be the problem here ?
Thank you for your time.
