Webservice parameter not visible

Question

Dear all,
            I have a problem over here. I create a function module and try to do some testing by suppling some input paramter. Result is successfully. Next, i go on to created a webservice for my function module and try testing it.
However, it did nt show a list of parameter that i could input for testing. Any one encounter similar problem here?

Thank you Peter.
Actually, while I imagine that I am missing something very simple, I have read the "Adding Parameters and Events to Portlets" document and based on your advice I just read it again.
As I understand it there are two apparently simple steps: 1. add the inputParameter to the provider.xml, and 2. add the implementation code.
The provider.xml, that I included in my first note on this thread, works with the exception that the Portal (on the page properties Parameters page)reports that the portlet has no inputParameters. I thought that the Portal might not processing the correct provider.xml. So I changed the spelling of the DefaultParameterDefinition in my provider to xDefaultParameterDefinition and ran the portlet in the portal again. It failed as expected.
The implementation code uses the same code as suggested in the "Making a Generic Public Parameter Receiving Portlet" section of the "Adding Parameters and Events to Portlets" document to retrieve the input parameter values. When the portlet is rendered in Portal the only code that is not executing is the code to display the input values.
Aside from whatever other advice you may provide, an answer to the following question could help to more narrowly focus my investigation.
While I know that an inputParameter cannot be processed without the implementation code, nonetheless, if I had a web portlet running in Portal and simply added an inputParameter to its provider.xml would the Portal show that the portlet had inputParameter in the page properties Parameters page?
Thanks,
