JMS MQ Connection closed in JSF 2 SessionBean
- by veote
I use Websphere Application Server 8 with MQ Series as Messaging Queue.
When I open close the connection in sessionbean in a "postConstruct" method and I use it in another method then its closed. My Code is:
import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.annotation.Resource;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import javax.jms.JMSException;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.Session;
import javax.jms.TextMessage;
@ManagedBean
@SessionScoped
public class MQRequest implements Serializable {
private static final long serialVersionUID = 1L;
@Resource(name = "jms/wasmqtest/wasmqtest_QCF")
private QueueConnectionFactory connectionFactory;
@Resource(name = "jms/wasmqtest/Request_Q")
private Queue requestQueue;
private QueueConnection connection;
private String text = "";
public void sendMessage() {
System.out.println("Connection in sendMessage: \n" + connection);
TextMessage msg;
try {
QueueSession queueSession = connection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
QueueSender sender = queueSession.createSender(requestQueue);
msg = queueSession.createTextMessage(text);
sender.send(msg);
queueSession.close();
sender.close();
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
text = "";
}
@PostConstruct
public void openConenction() {
System.out.println("Open Connection");
try {
connection = connectionFactory.createQueueConnection();
connection.start();
System.out.println("Connection in OpenConnectioN: \n" + connection);
} catch (JMSException e) {
e.printStackTrace();
}
}
@PreDestroy
public void closeConnection() {
try {
System.out.println("Closing Connection");
connection.close();
} catch (JMSException e) {
e.printStackTrace();
}
}
public void setText(String text) {
this.text = text;
}
public String getText() {
return text;
}
}
In PostConstruct method the connection is initialized:
[21.10.13 07:36:05:574 CEST] 00000025 SystemOut O Connection in OpenConnectioN:
com.ibm.ejs.jms.JMSQueueConnectionHandle@36c9b1a
managed connection = com.ibm.ejs.jms.JMSManagedQueueConnection@3657e8b
physical connection = com.ibm.mq.jms.MQXAQueueConnection@36618b6
closed = false
invalid = false
restricted methods enabled = false
open session handles = []
temporary queues = []
But in sendMessage() method it isnt and I get a ConnectionClosed Problem:

Do you have an idea why the connection is closed?
