Hi All,
I have a message flow MqInput--->Compute------>MqOutput.
On MqInput i am validating the input payload against xsd.
| Code: |
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Person">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" type="xs:string" name="Name" />
<xs:element minOccurs="0" type="xs:byte" name="Age" />
<xs:element minOccurs="0" type="xs:string" name="Address" />
<xs:element minOccurs="1" type="xs:int" name="Pin" />
<xs:element minOccurs="0" type="xs:string" name="Designation" />
<xs:element minOccurs="1" type="xs:string" name="Company" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
|
The elements Pin and Company are the mandatory.
While sending the request i am missing one all the mandatory element.
| Code: |
<Person>
<Name>xxxxx</Name>
<Age>xxxxxxxx</Age>
<Address>xxxxx</Address>
<Designation>xxxxxxxxxx</Designation>
<Company>xxxxxxxx</Company>
</Person> |
Here i have missed <Pin> element.
And The properties on MQInput node like.
Validation--->Validate(Content and Value)
Failure Action(Exception)
Parser Options---->Parse Timing(Complete)
When i send an invalid request its validating it properly.
On failure terminal of MQInputNode..
XMLNSC
Person
Name:CHARACTER:xxxx
Age:INTEGER:xxxxxxx
Address:CHARACTER:xxxx
Here i wanted to get the actual input message which i have sent.
| Code: |
<Person>
<Name>xxxxx</Name>
<Age>xxxxxxxx</Age>
<Address>xxxxx</Address>
<Designation>xxxxxxxxxx</Designation>
<Company>xxxxxxxx</Company>
</Person> |
How to get this.
if i have my like
MQInput--->RCD--->Compute---->OutPut
I am performing validations on RCD and connected Mqinput node catch terminal to my Error Handler flow here i am able to get the actual input message but i dont want to use RCD and need to capture the actual input message.
Thanks In Advance...  |

You have to delay the parse and/or validation i.e. no do it in the MQInput Node.
Then you can copy the Message tree to the Environment which will give you access to is in your failure processing.
If you read the message from the queue as a blob you can catch the cases where the XML is invalid and not just something like a field missing.
Then after copying it, you can parse/validate the message.

Thanks for your response.
So there is no way to do this on MQinput node..
As i said if i have the following nodes in flow.
MQInput--->RCD--->Compute--->Output
Then i am doing validation on RCD node in this i am able to get the input message but i wanted to do the same without having RCD node. |

That's doing double the work.
Link the failure terminal of the MQInput node to the RCD node and change the domain to BLOB. This should always give you the input message, unless you have a bad MQ message (message with a bad RFH for instance). The exception list should at this point already have information on what went wrong...
Have fun

I am able to get in the input until it reaches to missing mandatory element <Pin> .
When i send an invalid request its validating it properly.
On failure terminal of MQInputNode..
XMLNSC
Person
Name:CHARACTER:xxxx
Age:INTEGER:xxxxxxx
Address:CHARACTER:xxxx
i want to get these two elemets too...
<Designation>xxxxxxxxxx</Designation>
<Company>xxxxxxxx</Company>
Here i wanted to get the actual input message which i have sent.
<Person>
<Name>xxxxx</Name>
<Age>xxxxxxxx</Age>
<Address>xxxxx</Address>
<Designation>xxxxxxxxxx</Designation>
<Company>xxxxxxxx</Company>
</Person> |

So did you make your first node out the MQInput failure node an RCD node changing the domain to BLOB? That should have the full unparsed input message. And you want to leave it as BLOB. Any parsing you do might result in you having either no data (not an XML message) or partial data only (as you saw)...
Of course you could also use record and replay, or event emitting on rollback...
Have fun

Hi
My flow has below nodes.
MQInput--->Compute---->MqOutput
I am performing validation on MQInput node against xsd.
When the input message is unable to match the xsd its raising an exception up to now every thing is fine.
On failure terminal of MQInput node i am unable to see the exact input message which i have sent and i getting the message up to the parsing exception.
e.g i have 5 elements in my request message and parsing exception comes on 3rd element. Here i am able to see 2 elements which have parsed only. I wanted to get 5 elements which i have sent without using the RCD node(MQInput--->Compute---->MqOutput).

So which part of my above advice did you not understand?
What do you see in the BLOB? (Cast it to char if you need to read it)...
