[jboss-user] [JBossWS] - Problem calling a web service that requires empty input

[zhijun]

I'm trying to call a Web service using a method that doesn't take an input parameter. The WSDL for the input parameter is this:
<element name="getAllValues">
  |     <complexType>
  |         <sequence /> 
  |     </complexType>
  | </element>

I'm using call.invoke(Object[]) method to call it. I'm always getting the following ArrayIndexOutOfBoundsException no matter how I manipulate the Object[] for this call. It feels like JBossWS is having problem with this situation/WSDL description.

Is this a know issue or am I doing something wrong?

Thanks!
