Hi,
I'm new to JSP. I wrote a sample JSP app that writes/reads cookie. But
everytime I access the page, it seems that the cookie is not saved because
when I try to read all the cookies again, I don't see the values I just
entered. The following is my code. The form calls the same file to submit
the form.
<%
// GET Cookies
Cookie[] cookies = request.getCookies();
if (cookies.length > 0) {
out.println("Cookies sent from browser:<br>");
for (int i = 0; i < cookies.length; i++) {
Cookie cookie = cookies[i];
out.print("Cookie Name: " + cookie.getName() + "<br>");
out.println("Cookie Value: " + cookie.getValue() + "<br><br>");
}
} else {
out.println("No cookies from browser<br><br>");
}
// SET Cookies
String cookieName = request.getParameter("cname");
String cookieValue = request.getParameter("cvalue");
if (cookieName != null && cookieValue != null) {
Cookie cookie = new Cookie(cookieName, cookieValue);
response.addCookie(cookie);
out.println("<P>");
out.println("You just sent the following cookies to your
browser:<br>");
out.print("Name: " + cookieName + "<br>");
out.print("Value: " + cookieValue);
}
%>
<FORM METHOD=POST ACTION="jsp-cookies.jsp">
<BR>
Create a cookie to send to your browser:
<BR>
Name: <input type=text name="cname" value=""><br>
Value: <input type=text name="cvalue" value="">
<br> <INPUT TYPE=submit name=submit Value="Submit">
<P>
</FORM>
Thanks,
Lester
