Hi All,
In ESQL Compute node we can specify MessageSet,Type,Format of the output message with respective to a message set as in below,
| Quote: |
OutputRoot.Properties.MessageSet = 'ABCD12345678';
OutputRoot.Properties.MessageType = 'Output_Message';
OutputRoot.Properties.MessageFormat = 'XML'; |
In Java Compute Node is there any way to map the output message properties to a message set ? If possible , please let me know how to do that ?
Actually in our current assignment, using Java compute node we need to read message from flat file and create output message structure as defined in a message set.
Thanks & Regards,
Ranodip |

| If you can get the contents of the file into a string, you can use createElementAsLastChildFromBitstream(), specifying the message set, message type and message format as parameters. |

(I know this is an old post but I'm hoping to give a little bit back to this forum since it's been so helpful to me.)
I came across this post while struggling with the same issue as the OP.
After a bit of trial and error I came up with the code below to set the MessageType of the output message. In my case both the input and output message types are defined in the same message set so only the MessageType needed to be updated after the headers were copied.
- Dave
| Code: |
// Copy the message headers from the input to the output message
copyMessageHeaders(inMessage, outMessage);
// Change the output message's type
MbElement propertiesElem = outMessage.getRootElement().getFirstElementByPath("Properties");
if (propertiesElem != null) {
MbElement msgTypeElem = propertiesElem.getFirstElementByPath("MessageType");
if (msgTypeElem != null) {
msgTypeElem.setValue("csv_output_file");
}
else {
propertiesElem.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "MessageType", "csv_output_file");
}
}

This is a very old thread. The OP was obviously using the MRM domain.
People writing new message flows will probably be using DFDL, not MRM.
I suggest that you
- think carefully about what you are trying to do, and why
- if you cannot see how to solve the problem then open a new thread, and carefully explain what your problem is. |
