MQSeries.net :: View topic - Putting XML in a MbElement in java plugin

Hi i'm having problems to assign an xml in a MbElement, here is the problem.

I ve made a java plugin node that gets an xml from the message of the assembly. I read some values from this xml and use them in another class that returns a String, this String has an xml document that i want to put in the message that the plugin propagates.

I understand that i cant not create a new blank message in a plug in unless its an input plug in, so i use a copy of the message using the following code:

MbMessage newMsg = new MbMessage(assembly.getMessage());

This newMsg has an xml , but this xml is useless for me now, i need to delete it and assing my new xml (that is in the String ) to this new message.

I ve read the javadoc but i dont know how i can do this. is it possible to do this?

i detach de xml element, and that works find, but im having problems to assign the new xml, Here is the code :

MbMessage newMsg = new MbMessage(assembly.getMessage());
newMsg.getRootElement().getLastChild().detach();
MbElement element1 = newMsg.getRootElement().createElementAsLastChild("NONE");
MbElement element2 = element1.createElementAsFirstChild(MbElement.TYPE_VALUE);
element2.setValue(corbaExecutionResult);
MbOutputTerminal out = getOutputTerminal(_OUT_TERMINAL);
MbMessageAssembly newAssembly = new MbMessageAssembly(assembly, newMsg);
out.propagate(newAssembly);

where corbaExecutionResult is a java.lang.String that contains an xml like this one:

<?xml version = "1.0"?>

<Action>Answer</Action>
<Result>FAIL</Result>
<Resultado_Trans>2</Resultado_Trans>

</Key>
<Error>0</Error>
<ErrorMsg>Error:El Vehiculo Tiene un Tramite Similar Activo
(Folio 114100000040)</ErrorMsg>
</Operation>
</ConsultaControlVehicular>

This code does not throw an execption, but it does not work properly either because it propagates an empty Message, the setValue method its not working.

If i change this line:

MbElement element1 = newMsg.getRootElement().createElementAsLastChild("NONE");

using "BLOB" or "XML" instead of "NONE" the next exeption is thrown

(CORBAExecutionNode its my java class that extends from MbNode)

In english its something like this:

The broker has detected an error while procesing a message in the node {0}. An exeption has been received to stop immediately the process of the message.

Read the following message to see more details of the error.

And thats it, the text repeats like 3 times, and there are no more detailed messages about the error

Has anyone done something like this? or are there any suggestions?

Help please.
