Hi all, I followed the instructions in “Implementing simple OWS service” of the developer manual and go to the address “http://localhost:8080/geoserver/ows?request=sayHello&service=hello&version=1.0.0”
I get the following error.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<ows:Exception exceptionCode=“InvalidParameterValue” locator=“service”>

ows:ExceptionTextNo service: ( hello )</ows:ExceptionText>

</ows:Exception>

</ows:ExceptionReport>

They may guide me a little to know that the error occurs?
thank you very much
