I am trying to set some properties in the <usr> area of MQRFH2.
The following JMS code works fine for creating a simple property:
| Code: |
TextMessage xmlRsp = _session.createTextMessage();
xmlRsp.setText(msg);
xmlRsp.setObjectProperty("LE_Hdr","DOC1.RESP");
_sender.send(xmlRsp); |
Unfortunately in this case we must create a group with a sub property. Specifically I need the usr area to contain:
| Code: |
<usr>
<LE_Hdr>
<MsgType>DOC1.RESP</MsgType>
</LE_Hdr>
</usr> |
Any ideas as to how this can be done?
I have tried setting the value of LE_Hdr to "<MsgType>DOC1.RESP</MsgType>" but this does not work as the xml characters get replaced (e.g. < becomes < ).
P.S. The use of the usr area in this manner is covered in the WebSphere Application Programming Reference (chapter 17 - MQRFH2 Rules and Formatting). This can be found at:

Have you tried something like this?
xmlRsp.setObjectProperty("LE_Hdr.MsgType","DOC1.RESP");
I don't know if it will work but it seems intuitive... |

This seems like a sensible way of specifying structured properties but trying this generates an exception:
| Code: |
| javax.jms.MessageFormatException: MQJMS1058: Invalid message property name: LE_Hdr.MsgType |
It looks like the MQ JMS API does not support the concept of group properties. Does anyone have any approach that might work (can I get access to this information via some underlying MQ API)? |

| Rob, did you ever find a way in Java to create a group with sub-properties in the <usr> folder of a JMS message? |

Can you let me know if you were able to accomplish the nested headers for RFH2? I need to do the same..
Thanks very much,
simran |

| I thought that I read somewhere that you were only allowed simple (ie, one level) of headers in the usr folder. |

Bower is right. You are allowed to use only simple elements (no grouping) inside the "usr" folder.
It is mentioned in "Programming Guide" of MQSI. |

UP! 
I use RFH2 frequently but I'm a newbie in JMS. I can handle grouping in the usr folder with the broker, that's why I wonder the paragraph in the manual referenced by vmurali:
| Quote: |
The content model of the <usr> folder is as follows:
- Any valid XML name can be used as an element name, providing that it doesn’t contain a colon
- Only simple elements, not groups, are allowed
- All elements take the default type of string, unless modified by a dt="xxx" attribute
- All elements are optional, but should occur no more than once in a folder |
In this case I have two possibility:
(1) writing to usr folder with a special selector
(2) writing a customized folder in JMS
My problems:
(1): not all XML names are working with setstringproperty() !  I tried hyphen, point,...
(2): how can I build a custom folder in JMS?
TIA,
Tibor |

Flatten/unmarshal your XML and then put that as a single string in the /usr folder.

I *can* flat the usr tags... but I was an idea about enterprise standard for usr folders with application specific tags, namely application-area, eg:
| Code: |
<usr>
...
<application-area>
<filename>xxx.zzz</filename>
...
</application-area>
</usr>
|
Ok, I drop this because it is not allowed by manual. But sending messages throw exception when I try a workaround:
msg.setStringProperty("applicationarea.filename","filename");
Another question was how can I implement this in JMS:
| Quote: |
Independent software vendors can choose other names for their folders. However, to avoid naming problems, we recommend that vendors prefix their chosen folder name with their internet domain name; for example, a vendor with domain name ourcompany.com might name its folders:
com.ourcompany.xxx or com.ourcompany.ourData |

Any news how to put nested tags in <usr>?
I've got same problems. The broker aspects a nested xml
structure....
I'm writing a java program to solve this. I only can fix
it with native MQ library and com.ibm.mq.MQMessage
With JMS it is not possible....any sugestions because
i would like to use JMS and Spring |

Have you tried following?
msg.setStringProperty("application-area","<filename>xxx.zzz</filename>"); ??
