Ok,
I type in the following url http://localhost/Forms/form.jsp
Now what should happen is it should do what is in the case 1 of the switch.
But it doesn't. It gets caught up on the fact that there is no Page
paramater.
I have come from the world of asp, and something like this is achieved
simply by doing this.
If len(request("Page")) < 0 Then
sPage = "1"
End If
It doesn't matter if "page" is there or not, if page is there in the form of
form.asp?Page= then the length = 0 if it is form.asp then length = 0
How do you do this in java?
The reason I have the else in there is I have to convert sPage into a
integer cause switch doesn't accept strings unlike VB's Select which does.
