How can I pass a parameter?

[qingwu wang]

Hello everyone!
I want to pass a parameter to next servlet page.I try to do this.but I cannt get what I want to.
In the code,*i* is a variable in the 'for loop'.

<a href="<%=encodeURL("/servlet/util.Void?location=i", request, response)%>">

How can I translate a string to int?

int a=Integer.parseInt(req.getParameter("location")==null?"0":req.getParameter("location"));

In your code, 'i' is being treated as part of the whole string. You need to reference the *value* of the variable i, so place it outside the quotes.

<a href="<%=encodeURL("/servlet/util.Void?location=" + i, request, response)%>">

Also, encodeURL is your own method, right? because HttpServletResponse's version does not take request and response as a parameter.

You might want:
<a href="<%= response.encodeURL("/servlet/util.Void?location=" + i) %>">
