Hi,
I hope everybody doing good.
I have small scenario by using JCN.
my flow looks as below
MQINPUT -->JCN --> MQOUTPUT
I had given message message domain As XMLNSC for MQINPUT node.
When i debug my flow am able to Message tree properly
When trying access the payload element am getting Runtime exception.
Please let me know do i need to do any configurations in IIB JCN.
Please find my JCN code as below :
| Code: |
MbOutputTerminal out = getOutputTerminal("out");
MbMessage message = assembly.getMessage();
MbMessage newMsg= new MbMessage(message);
try {
// optionally copy message headers
copyMessageHeaders(message, newMsg);
// ----------------------------------------------------------
// Add user code below
MbElement root = newMsg.getRootElement();
MbElement body = root.getLastChild();
String bodymessage = body.getValue().toString();
MbMessageAssembly outAssembly = new MbMessageAssembly(assembly,
newMsg);
out.propagate(outAssembly);
// End of user code
// ----------------------------------------------------------
} catch (MbException e) {
// Re-throw to allow Broker handling of MbException
throw e;
} catch (RuntimeException e) {
// Re-throw to allow Broker handling of RuntimeException
e.printStackTrace();
} catch (Exception e) {
// Consider replacing Exception with type(s) thrown by user code
// Example handling ensures all exceptions are re-thrown to be handled in the flow
throw new MbUserException(this, "evaluate()", "", "", e.toString(),
null);
}
// The following should only be changed
// if not propagating message to the 'out' terminal
}
|
Thanks in Advance for your help.
Regards,
Anil. |

Well you have a new message, so you copy the headers...
What you access as Body is in fact the last child of OutputRoot.... which at that point points to the last header.
You need to declare a parser and then copy a body... Look at the samples with JCN. This will help you build your code...
Have fun

| You don't mention the exception anywhere. Are you able to observe & communicate the error condition? |

That's entirely nonsense and doesn't do anything useful. |

Correct.
Should use
bodymessage = body.getlastchild().getValue().toString(); if xml message is having only one root tag with value.
Posting queries without correct info does nt make sence. |

The XML document will have been turned into a complete message tree.
You do not need to parse it again.
You just have to understand how to write Broker code in a JCN. |
