Java code to refresh browser

Question

Whenever a user logs in(into an app which I've been working on), he will be redirected to his home page, which needs to be refreshed one time. I have to write the code in .java file to basically refresh the browser.

How can this be achieved with java. I know it can be done using javascript, but I have to achieve the above in a .java file. Any ideas ???

Answer 1

Just use code like this:

response.setHeader("Refresh", "0; URL=http://your-current-page");

Answer 2

 response.setHeader("Refresh", "0; URL=" + request.getContextPath() + "/test.do?methodname=test&param=test"); 

Instaed of hardcoding the URL (URL=http://your-current-page). you can use below. 

request.getContextPath()
 will get respective ip address 

Answer 3

You want to set a cookie that will cause a page refresh.
