Re: How can these query data be got?

[KE LI]

Hi Dave,
  Thanks for your quick reply. Suppose that I input this link
"xxx/welcome.do?param1=hello&param2=world&paramList=element1&paramList=element2&paramList=..."
into the link bar in the browser and run it. How can S2 knows to put "hello"
into param1 and "world" into param2 in the welcome action object?
  Could you please kindly explain the procedure? Or lets say, if I define
another field "param4", why not giving "hello" to "param4" instead of
param1?
  Besides, suppose that I just run this link
"xxx/welcome.do?param1=hello&param2=world&paramList=element1&paramList=element2&paramList=..."
in the browser, only the default method "execute" will be called, right?
  Thanks a lot!
