Sorry. I did not exactly understand what you meant..
I tried the following web service
public class SimpleTestVoid
{
public *String* echo( String message ) *throws Exception*
{
return message;
}
}
Even though the method is throws exception, the client is successfully able
to invoke the web method and everything is working great.
Thanks,
Paul
