Can't find cookie if path is set to /

Currently using Java I am able to create a cookie and later retrieve it via Cookie[] browserCookies = request.getCookies();
The issue comes when I try create a cookie and set its path with cookie.setPath("/"); I can no longer find it later when the below code. It has a max age of 30 days so I know it's there and I see it get created but I can't find it any longer after that initial creation.
Here's what I have now which works when not setting a path to "/":
Look for a cookie with a specific name:
Cookie[] browserCookies = request.getCookies();
boolean foundCookie = false;
if (browserCookies != null) {
for (int i =0; i< browserCookies.length; i++) {
if ("foo".equalsIgnoreCase(browserCookies[i].getName())) {
foundCookie = true;
}
}
}
based on foundCookie, I do something but also based on that I create a new cookie if not found:
if (!foundCookie) {
Cookie fooCookie = new Cookie ("foo", "barValue");
fooCookie.setMaxAge(30 * 86400);
//fooCookie.setPath("/"); // If I set this, I can no longer find it later by the name
response.addCookie(fooCookie);
}
Thank you for any help

Not able to get cookie in different context

i am setting cookie in context A and trying to get in context B in same domain . I am writing this code ....
Cookie cook= new Cookie("Name","value");
cook.setPath("/");
cook.setDomain(".foo.com");
response.addCookie(cook);
what is wrong here ? This is how i am getting the cookie in another context ..please note that my code is working fine in same context
Cookie cookie = null;
Cookie[] cookies = null;
cookies = request.getCookies();
out.println(cookies);
for (int i = 0; i < cookies.length; i++){
cookie = cookies[i];
if("Name".equals(cookie.getName( ))){
out.println("Name : " + cookie.getName( ) + ", ");
out.println("Value: " + cookie.getValue( )+" <br/>");
}}

Try to give the cookie a lifetime.
cookie.setMaxAge(86400) // 24h
A cookie without lifetime is bound to the browsing session. You might be in a different session when browsing in a different context.

Delete a cookie by its value

How do I delete a cookie by its value?
In my.jsp page I am setting the cookie
String timeStamp = new SimpleDateFormat("dd:MM:yyyy_HH:mm:ss:SSS").format(Calendar.getInstance().getTime());
timeStamp = timeStamp + ":" + System.nanoTime();
String loc = "/u/poolla/workspace/FirstServlet/WebContent/WEB-INF/"+timeStamp;
Cookie cookie = new Cookie("path", loc);
Multiple users will have cookies with the same name but different loc values,
So, How do I get the cookie value in servlet.java and delete a particular loca value cookie??

Cookies are not same for each user. Generally cookies are tied to the client/user/browser which is accessing the JSP/application and each client can have a cookie value of its own.
When you delete a cookie you just delete it for the client which has made the request to your application. Rest of the clients will still have their own cookie without any effect in the value. Hence, you need not to worry about deleting a cookie may affect multiple users.
In order to delete a cookie, first get all the cookies from request and delete the cookie which has particular name/value.
public void delete(MyType instance) {
Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (Cookie cookie : cookies) {
if (cookie.getName().equals("test")) {
cookie.setValue(null);
cookie.setMaxAge(0);
cookie.setPath(theSamePathAsYouUsedBeforeIfAny);
response.addCookie(cookie);
}
}
}
}

You will need to call getCookies() on the request and loop through them until you find the one you're looking for.

here is a little simple example tha might help you
//declaring a cookie
Cookie cookie = new Cookie(name, value);
//getting the cookie name
String name = cookie.getName()
//getting the cookie value
String value= cookie.getValue();

Getting wrong value from session in javascript, How to use session in javascript?

I am using following code to get session variable value in javascript embedded in a JSP:
var numberOfPages= '<%=session.getAttribute("numberOfPage")%>';
I am getting a wrong value (old value) when I hit the page for the first time but when I refresh the page, then I'm getting the correct value. Please help me.
Servlet code:
HttpSession session = request.getSession(false);
if( session == null ) {
session = request.getSession(true);
}
String numberOfPage = Integer.toString(noOfPages);
session.removeAttribute("numberOfPage");
session.setAttribute("numberOfPage", numberOfPage);
Jsp (javascript) Code:
if(<%=session.getAttribute("numberOfPage")%>!= null)
numberOfPages= '<%=session.getAttribute("numberOfPage")%>';

session.getAttribute() returns an Object, try to cast it.

How to get asp.net created cookies in Java servlet?

How to get ASP.NET created cookies in a Java servlet?

if( cookies != null ){
out.println("<h2> Found Cookies Name and Value</h2>");
for (int I = 0; I < cookies.length; I++){
cookie = cookies[I];
out.print("Name : " + cookie.getName( ) + ", ");
out.print("Value: " + cookie.getValue( )+" \n");
}
}else{
out.println(
"<h2>No cookies founds</h2>");
}
Whats wrong with my code?

The equals character is a reserved character in a cookie value. The specification compliant way of fixing this is to quote the cookie value by surrounding it with double quotes. However, some browsers don't handle this very well. If you are using Tomcat you can set the system property -Dorg.apache.tomcat.util.http.ServerCookie.ALLOW_EQUALS_IN_VALUE=true to allow equals in cookie values.
