org.xml.sax.SAXException: Deserializing parameter

Hi,

I have a trouble in my testing program. I create a web service (Hello) with
Eclipse WTP3.3. Its wsdl is the attachment-Hello.wsdl.(
http://www.nabble.com/file/p12492378/Hello.wsdl Hello.wsdl )
The "Hello" web service has two methods, one is "sayHello" with a parameter
"name", the other is "sayHi" WITHOUT any parameter. They both will return a
result in String type.
Then I create a program WSIFInvoke.java(
http://www.nabble.com/file/p12492378/WSIFInvoke.java WSIFInvoke.java ) with
WSIF2.0 api.
When invoking the sayHello method with a parameter, it is fine. But it
doesnt work when invoking the sayHi without a parameter. And the error is
below.
