Hello all!
I successfully built a plugin node that creates a message including "normal" MQMD and body elements. When I add the code for the RFH2 header, the MQPUT of the MQOutput node that takes the output of my plugin node fails with Reason Code = 2334 - "MQRC_RFH_ERROR
(2334, X’91E’) MQRFH or MQRFH2 structure not valid."
My code looks like this:
| Code: |
MbElement elemOut = elemOutRoot.getFirstElementByPath("/MQMD/Format");
elemOut.setValue("MQHRF2 ");
MbElement rfh2 = elemOutRoot.getFirstElementByPath("/MQMD");
rfh2 = rfh2.createElementAfter(MbElement.TYPE_NAME);
rfh2.setName("MQRFH2");
setProperty(rfh2, "Version", 2);
setProperty(rfh2, "Format", "MQSTR ");
setProperty(rfh2, "Encoding", encoding.intValue());
setProperty(rfh2, "CodedCharSetId", ccsid.intValue());
setProperty(rfh2, "Flags", 0);
setProperty(rfh2, "NameValueCCSID", 1208);
// helper methods ...
protected MbElement getcreateLastChild(MbElement elem, String name)
throws MbException
{
return getcreateLastChild(elem, name, MbElement.TYPE_NAME);
}
protected MbElement getcreateLastChild(MbElement elem, String name, int flag)
throws MbException
{
MbElement elemChild = elem.getFirstElementByPath("./" + name);
if (null != elemChild)
return elemChild;
elemChild = elem.createElementAsLastChild(flag);
elemChild.setName(name);
return elemChild;
}
protected MbElement setProperty(MbElement elem, String name, byte[] value)
throws MbException
{
MbElement attribute = getcreateLastChild(elem, name, MbElement.TYPE_NAME_VALUE);
attribute.setValue(value);
return attribute;
}
protected MbElement setProperty(MbElement elem, String name, String value)
throws MbException
{
MbElement attribute = getcreateLastChild(elem, name, MbElement.TYPE_NAME_VALUE);
attribute.setValue(value);
return attribute;
}
protected MbElement setProperty(MbElement elem, String name, int value)
throws MbException
{
MbElement attribute = getcreateLastChild(elem, name, MbElement.TYPE_NAME_VALUE);
attribute.setValue(new Integer(value));
return attribute;
}

I dumped the generated message tree (structure and values) and it looks exactly like the tree my custom node receives if the input message includes an RFH2 header.
-- Any ideas?
Thanks and

Have you managed to fix this as I'm getting the same error and can't find out what is wrong with it. Have tried loads of things but am just about at the end of my tether.
Cheers Donald |

Hello Donald
Yes, I managed to get this running.
Maybe this code snippets will help you:
| Code: |
MbElement elemOut = elemOutRoot.getFirstElementByPath("/MQMD/Format");
elemOut.setValue("MQHRF2 "); // Note: not MQRFH2
MbElement rfh2 = elemOutRoot.getFirstElementByPath("/MQMD");
rfh2 = rfh2.createElementAfter("MQHRF2");
// set version = 2 and so on
|
If you have a java plugin INPUT node, you'll probably have to add an ESQL node that fills all the mandatory MQMD fields like CorrelationID and so on.

Thanks for the info. I didn't know about being able to create other types of element so had just as MbElement.TYPE_NAME. Changing this to MQHRF2
has made all the difference. Would have been good if this had been documented somewhere
Thanks again
Donald  |
