Hi,
I am having an issue with putting data in the usr folder in MQ from VB.Net application.
I having no problem puting the messages, the body of the message going correctly, i am trying to put some data in the usr folder, but when i browse the message using rfhutilc all RFH2 folders appaers in the "message data" not in usr tab.
Can anyonle please help me on this?
My sample code is below:
--------------------------------------------------------------------------
Imports IBM.WMQ
'Imports IBM.WMQSOAP
'Imports IBM.XMS
Dim strUsr As String = "<msgtype>TestMsgType</msgtype>"
Dim strUSRBytes As Byte() = System.Text.Encoding.ASCII.GetBytes(strUsr)
Dim iMsgLen As Integer = (CInt((strUsr.Length)))
PutMsg = New MQMessage
PutMsg.Format = MQC.MQFMT_RF_HEADER_2
PutMsg.WriteString(MQC.MQRFH_STRUC_ID) ' StrucID
PutMsg.WriteInt4(MQC.MQRFH_VERSION_2) ' Version
PutMsg.WriteInt4(MQC.MQRFH_STRUC_LENGTH_FIXED_2 + iMsgLen) ' StrucLength
PutMsg.WriteInt4(MQC.MQENC_NATIVE) ' Encoding
PutMsg.WriteInt4(MQC.MQCCSI_DEFAULT) ' CodedCharSetID
PutMsg.WriteString(MQC.MQFMT_RF_HEADER_2) ' Format
PutMsg.WriteInt4(MQC.MQRFH_NO_FLAGS) ' Flags
PutMsg.WriteInt4(1208) ' NameValueCCSID
PutMsg.WriteInt4(iMsgLen) 'NameValueLength <jms>
PutMsg.WriteString(strUsr) ' NameValueData <usr>
MESSAGE = "<?xml version=""1.0"" encoding=""UTF-8""?><AAA><BBB>TEST</BBB></AAA>"
PutOptions = New MQPutMessageOptions()
PutMsg.WriteString(MESSAGE)
putmsg.Write(
Queue.Put(PutMsg, PutOptions)

Moving to more appropriate forum.
If you are using an RFH header you'd be better advised to use XMS than try building your own. There is the little problem of alignment etc...
Have fun

Look up on the net an exemple of JMS. XMS is nothing else but JMS ported to a non Java environment...
Have fun

I believe you are trying to set some user properties. Have you tried using methods like SetIntProperty(), SetStringProperty() of MQMessage class? These methods can be used to set user defined properties.
For example:
Try
msg = New MQMessage()
msg.WriteUTF("This is a test message from VB app with properties")
msg.SetStringProperty("MyProp", "value")
q.Put(msg)
Catch ex As Exception
Console.Write(ex)
End Try |

Now i am able to put value into the USR folder. Now I have one small issue there. I am trying to put a below value into the usr folder.
<Test>Test Message</Test>
When i check the message in USR folder throught RFHUtil, it shows as below
<Test dt="string">Test Message</Test>.
Is there anyway to eliminate dt="string" from that tag? |

I think the answer is probably "no".
Out of interest, why do you need to eliminate it? |

We are putting messges there and the other team read that message and do further process.
I have asked the same question to that team, no answer from them. They keep on ask us that can we send without that element dt="string" |

Strictly speaking it's an attribute not an element, which is why it shouldn't make any difference. Except to help a well-behaved recieving application.
I agree with my most worthy associate that there's probably nothing you can do.

Maybe they would like to say the reason.
I think the dt="string" is there because it is intended to be useful. If it is missing, something else might break when you least expect it.
Are they using some incompatible libraries for parsing messages? Maybe (just my opinion) when you are originating a message using MQ-provided classes, it should be consumed using MQ-provided classes too, to give greatest chance of success. |

AFAIK it's intended to describe the datatype of the content for casting & conversion purposes.

I think that if this attribute isnt present then the data is assumed to be a string (I certainly dont remember dt="string" all over the elements in the usr folder when using JMS).
Its probably that the XMS API is adding it in to be nice, I dont know if theres a way to disable it however and as you say, theres probably no need. |
