MQSeries.net :: View topic - Extract text from message (image included)

Hello!

Our former thread about this is so messy now so we started this new one.
We still have problems with extracting the text from the TextMessage.

We send the message like this from a JSP-page in WAS:

TextMessage textMessage = queueSession.createTextMessage();
textMessage.setText(messageText);
setWSProps(textMessage);
jmsQueueSendManager.send( properties.getProperty("squeue"), textMessage);
System.out.println("Class name: " + textMessage.getClass().getName());
System.out.println("The message\n" + textMessage);

When we send the message we also set theses properties:

public void setWSProps(Message message)
{
try
{
message.setIntProperty("JMS_IBM_Encoding", 273);
//message.setIntProperty("JMS_IBM_MsgType", 0);
message.setIntProperty("JMS_IBM_PutApplType", 31);
message.setStringProperty("JMS_IBM_Format", "MQSTR");
message.setIntProperty("JMS_IBM_Character_Set", 1208);
}
catch(Exception e)
{
e.printStackTrace();
}
}

The new properties does not seem to do anything, so I guess we can remove it??

From the JSP-page we send this string "1140605792567" (System.currentTimeMillis())

When we send the message we get this output:
[2006-02-22 12:36:21:282 CET] 00000045 ConnectionFac W J2CA0294W: Deprecated usage of direct JNDI lookup of resource jms/WSQueueFactory. The following default values are used: [Resource-ref settings]

We receive the message from an other JSP-page like:
try
{
Message message = jmsQueueReceiveManager.receiveNoWait( properties.getProperty("rqueue") );

if (message != null)
{
System.out.println("Class name: " + message.getClass().getName());
if(message instanceof com.ibm.ws.sib.api.jms.impl.JmsTextMessageImpl)
{
messageText = ((com.ibm.ws.sib.api.jms.impl.JmsTextMessageImpl)message).getText();
}
else if (message instanceof BytesMessage)
{
byte[] bytes = new byte[20];
((BytesMessage)message).readBytes(bytes);
messageText = new String(bytes);
}
else if (message instanceof MapMessage)
{
messageText = (String) ((MapMessage)message).getObject("messageString");
}
else if (message instanceof ObjectMessage)
{
messageText = (String) ((ObjectMessage)message).getObject();
}
else if (message instanceof StreamMessage)
{
messageText = ((StreamMessage)message).readString();
}
else if (message instanceof TextMessage)
{
messageText = ((TextMessage)message).getText();
}
}
else
{
messageText = "Received nothing! (Message null)";
}

System.out.println("The message:\n" + message);
System.out.println("The text:\n" + messageText);

jmsQueueReceiveManager.close();
jmsQueueReceiveManager.terminate();
}
catch(Exception e)
{
e.printStackTrace();
}

The total output from the receiving side is

As you can see the payload seems to be gone???

We got this overview image at this url:
http://www.dsv.su.se/~fr-ander/images/Overview.jpg

We send to the queue in WAS: jms/WSQueue
Down to the queue in MQ: MQToWL
MQToWL is a remote queue, everything put here gets sent back to the WAS: jms/WSQueue2

Somewhere the text in the message gets removed or encoded. So if any one know how to solve this please let us know.
How do we extract the message????
Any explanation is also welcome!

Best regards
