Hi,

I'm kinda new to java compute.
Am trying to use a simple java compute where an xml string need to be passed as output from the java compute node.

I tried with the following code, but it does not return any output.

public class TMP_MF_JavaCompute extends MbJavaComputeNode {
public void evaluate(MbMessageAssembly assembly) throws MbException {
MbOutputTerminal out = getOutputTerminal("out");

MbMessage message = assembly.getMessage();
MbMessage outMessage = new MbMessage();
MbMessageAssembly outAssembly = new MbMessageAssembly (assembly, outMessage);

try
{
MbElement root = outMessage.getRootElement();

MbElement mqmd = root.createElementAsFirstChild("test");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE, "Format", "XML");
}
catch (Exception e)
{e.printStackTrace();}

out.propagate(outAssembly);
}
}

Plss tell me wat kind of modification i need to do to send out a string.

Thanks in advance...
