Subject: handling Query strings
> Hi All
>
> When we more than one querystring in JSP, how do we
> read then in the next page, because if we use
> request.getQueryString(), it returns the whole string
> after '?'
>
> and if we use request.getParameter("parameterName"),
> it works fine, but when requests come from different
> pages and they do not contain this parameter, it
> throws nullpointer exception.
>
> In detail:
>
> abc.jsp?id=123, in abc.jsp we can read id by using
> request.getParameter("id"), but if a request comes
> from another page, say, xyz.jsp to abc.jsp without any
> parameter, abc.jsp throws expection
>
> Is there any better way of dealing with these
> querystrings/parameters. any examples/links are
> highly appreciated
