Hi All,
I am using WMB 6.0 and MQ 5.3. In one of our MsgFlow we are getting messages from HTTPInput node and need to put them it in a MQQueue.So to put a queue we need to add a MQMD header in output message and the Java code we have developed for that is in below :
| Quote: |
MbElement mqmd = outRoot.createElementAfter("MQHMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","XMLNSC"); |
as given in toolkit help
| Quote: |
| http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r0m0/index.jsp?topic=/com.ibm.etools.mft.doc/ac30430_.htm |
This code actually placing the MQMD as first child of ROOT i.e. before Properties. But as per my knowledge the MQMD should be placed after Properties. So we have modified the code and used as in below:
| Quote: |
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQHMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","XMLNSC"); |
In MQOutput node properties, we have selected Advanced-> New Message Id to assign a new message Id for output message.
But for both the cases above it not able to put message in queue and giving MQRC 2097 error. Should we need to add anything in MQMD ?
Thanks in advance,
Ranodip |

use the search button and search for 2097, there are a number of posts which may fit your needs.

Place trace node inside flow and check your tree structure.
You will see where the problem is. I hope
| Quote: |
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQHMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","XMLNSC"); |
PS. Shouldn't it be:
| Quote: |
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","MQSTR"); |

Hi Marcin,
While I am using
| Quote: |
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","MQSTR"); |
the MQMD header is not generating and in the exception list I am getting
| Quote: |
(0x03000000):Severity = 3
(0x03000000):Number = 2310
(0x03000000):Text = 'Could not create parser'
(0x01000000):Insert = (
(0x03000000):Type = 5
(0x03000000):Text = 'MQMD' |
But when I have changed the code to
| Quote: |
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQHMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","MQSTR"); |
It is still not able to put message in queue and the trace is as in below:

Hi,
Using ESQL I am able to create a MQMd header from scratch and put the message in queue. The code is as below:
| Quote: |
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN 'MQMD';
SET OutputRoot.MQMD.StrucId = MQMD_STRUC_ID;
SET OutputRoot.MQMD.Version = MQMD_CURRENT_VERSION;
SET OutputRoot.MQMD.MsgType = MQMT_DATAGRAM;
SET OutputRoot.MQMD.Format = MQFMT_RF_HEADER_2 ;
SET OutputRoot.XMLNSC = InputRoot.XMLNSC; |
But in Java I am not able able to find how to add these values to corressponding MQMd properties ? Are MQMD_STRUC_ID, MQMD_CURRENT_VERSION etc. conatants available in MB Broker java packages ? |

Another example with MQHMD. This is correct name of parser class.
| Code: |
MbElement root = msg.getRootElement();
MbElement body = root.getLastChild();
MbElement mqmd = body.createElementBefore("MQHMD"); |
You mentioned that it works with ESQL but please check Message Context Arrtibute of MQOutput.
Try "Default".
Is it full message tree you showed us ?

Hi Marcin,
The problem got splved now. Yes the problem root was with Message Context property of MQOutput node. By default it comes as Pass all which I changed to Set All. So after changing it is working fine even with
| Quote: |
| mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","XMLNSC" |
.
Thanks a lot for all of your helps.
