We are using a version 5 broker.
I recieve a message from a HTTPInput node, with Message Domain='XMLNS'.
I'm supposed to deliver that to a Websphere Application Server application. That application requires:
1) A valid MQMD header
2) A valid MQRFH2 header
3) Some specific values set in MQRFH2.usr
4) A body in the MRM domain.
It's easy to do 3) in a Compute node and 4) in a Reset Content Descriptor node, but how do I do 1) and 2) in the easiest and best way, as there is neither MQMD or MQRFH2 in the message when it arrives from the HTTPInput node (only Properties, HTTPInputHeader and the body)?
Anybody got any good examples to take a peek at? |

here is an example of a way of building the MQMD header in a compute node:-
Declare output_cursor reference to OutputRoot;
Create Nextsibling of output_cursor.Properties domain 'MQMD';
Set output_cursor.Properties.ReplyIdentifier = X'000000000000000000000000000000000000000000000000';
Set output_cursor.MQMD.StrucId = MQMD_STRUC_ID;
Set output_cursor.MQMD.Version = MQMD_CURRENT_VERSION;
--Set OutputRoot.MQMD.MsgId = UUIDASBLOB;
Set output_cursor.MQMD.MsgId = (UUIDASBLOB||x'0000000000000000');
Set output_cursor.MQMD.CorrelId = X'000000000000000000000000000000000000000000000000';
Set output_cursor.MQMD.Format = MQFMT_STRING;
Set output_cursor.MQMD.Persistence = MQPER_PERSISTENT;
Set output_cursor.MQMD.ReplyToQ = ' ';
Set output_cursor.MQMD.ApplIdentityData = ' ';
Set output_cursor.MQMD.Persistence = MQMD_CURRENT_VERSION;
To build the MQRFH2 you can check the IBM manuals for the format and required / optional fields for the RFH2 and also point the MQMD to that fact that an MQRFH2 header exists. |

Ok, I just need to set the domain, I don't need to name that node? |

I am not sure i understand your reply. The nextsibling creation creates the domain under the meassge properties and then you have the children of that domain which creates a WebsphereMQ header. |

use
| Code: |
| Create Nextsibling of output_cursor.Properties domain 'MQMD' name 'MQMD'; |
Check out the manual for the right order as the code is from memory....
Enjoy

Reading the help texts gave me the impression that just giving DOMAIN and not NAME would create an anonyous node that was parsed with a given parser, and then the subsequent "SET OutputRoot.MQMD.xxx" statements would create their own node, as I took the lvalue path in SET as a series of names.  |
