Hi,
We are facing an issue when the WID workflow is trying to put a message to MQ queue and get another message from another queue. We are using a single “invoke” action configured to request reply operation. The workflow is able to put the message successfully on MQ Queue but while receiving the message from queue – it’s throwing the error:

This is a parser error, so kindly check the receving XML is in good format, and it meets with your requirements...

Hello Gayathri,
Yes, the XML is well-formed...The MQ Receive works with a business object input  with an input message as follows:
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<p:MQData xsi:type="p:MQData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://MQ_PoC">
<message>abcd</message>
<messageId>2345</messageId>
</p:MQData> |
But it doesn't work  when we tried passing an input via MQ (a plain XML with one string value):
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<p:sendReceive_._type xsi:type="p:sendReceive_._type" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://MQ_PoC/sendReceive">
<message>abcd</message>
</p:sendReceive_._type> |
Any clue on why is it so..?
Thanks,
Raghavendra. |

if the message doesn't match up with the BO that you have created, it will throw exception.

Examine the root exception - the XML looks wrong
Copy and paste your xml into eclipse and validate it.
This exception is usually caused by a misspelt tag name. |
