[Users] XQuare \ SU provide JBI setup

[Dach]

Hello all, 

I currently try to set up a JBI file in order to use the storedQuery operation and I'm facing a problem when a message is send to my component.

The message (in the fault) returned is: 

Code:
Failed to process the exchange : NullPointerException : null




Here is my JBI file:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<!-- 
	JBI descriptor for the PEtALS' "petals-bc-xquare" component (XQuare).
	Originally created for the version 2.0 of the component.
 -->

					   return $u
					} </result>]]>
				</xquare:storedQuery>
			</xquare:storedQueries>						
		</jbi:provides>
	</jbi:services>
</jbi:jbi>



The input message:

Code:
<storedQuery id="0">
<param name="serialNumber">269</param>
</storedQuery>



The message in the petals console is:

Code:

Could you tell me how to configure a storedQuery in a JBI XQuare component file and what is wrong in my case?

Thank you.
