I'm following instructions on

http://docs.geoserver.org/stable/en/developer/programming-guide/ows-services/implementing.html

to learn how to implement custom OWS service..

I pretty much followed all the initial instructions and copied hello-1.0.jar
in C:\geoserver-2.0.2\webapps\geoserver\WEB-INF\lib and restarted geoserver

when I go to
http://localhost:8080/geoserver/ows?request=sayHello&service=hello&version=1.0.0

I get

<ows:ExceptionReport version="1.0.0" xsi:schemaLocation="
http://www.opengis.net/ows
http://localhost:8080/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd";>
-
<ows:Exception exceptionCode="InvalidParameterValue" locator="service">
<ows:ExceptionText>No service: ( hello )</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>


geoserver logs below.

any ideas why this would be?

thank you
