java - The method createConnection() is undefined for the the class ConnectionFactory -

i have been trying learn activemq , jms. when compile following code above exception. although, have attached right jar files jms , activemq. eclipse asks me add cast connectionfactory object when try create connection (i.e. connectionfactory.createconnection()) using connectionfactory object. codes see everywhere on internet same have written.

import javax.jms.connection; import javax.jms.connectionfactory; import javax.jms.deliverymode; import javax.jms.destination; import javax.jms.messageproducer; import javax.jms.session; import javax.jms.textmessage; import org.apache.activemq.activemqconnection; import org.apache.activemq.activemqconnectionfactory; public class jmsproducer { public static void main(string[] args) {      try {          // create connectionfactory          connectionfactory connectionfactory=new activemqconnectionfactory("admin", "admin",         activemqconnection.default_broker_url);          // create connection           connection connection = connectionfactory.createconnection();          //error seen in above line          connection.start();          // create session          session session = connection.createsession(false, session.auto_acknowledge);          // create destination          destination destination = session.createqueue("testq");          // create messageproducer session queue          messageproducer producer = session.createproducer(destination);          producer.setdeliverymode(deliverymode.non_persistent);          // create messages          textmessage message = session.createtextmessage("helloworld");          producer.send(message);          session.close();          connection.close();          system.out.println("message sent");       }      catch (exception e) {          system.out.println(e);          e.printstacktrace();      }   }  } 

sholud have done activemqconnection connection = connectionfactory.createconnection(); instead of connection connection = connectionfactory.createconnection();. code running fine.
