I have a struts2 webapplication which i am integrating with another forum webapplication.When the user logs into the Struts2 application, i want to maintani his session in forum also and forum should not ask him to login again.For thsi i am using a cookie which is not at all getting generated.
I changed the code in Jsp and installed the Web developer toolbar. The cookie is not at all coming when i enter Jforum application from Main application. I have 2 separate wars. I am highly puzzled what else i have to do? Please find the jsp,Util class files.
I am not doing cookie.setDomain(domain); is it causing the issue?


This is my main application URL from where i will move to Jforum after clicking a link in this jsp


This is my Jforum URL which i get when the user moves to Jforum from main application


I have the following code in jsp where cookie is formed and then the user clicks on the hiper link. Is this not the way???

<authz:authorize ifAnyGranted="ROLE_ADMIN,ROLE_EMPLOYER,ROLE_EMPLOYEE">
User userObj = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String username = userObj.getEmail();
String password = userObj.getPassword();
String encrypted = CookieUtil.makeSSOCookieValue(username, password);
Cookie cookie = new Cookie("sso-auto-login", encrypted);
cookie.setMaxAge(120000); // 10 hours in seconds (can be -1 for session).
//cookie.setDomain(domain); // Full qualified server domain.
<a href="http://localhost:8080/jforum/" cssClass="thf_line">COOKIE FORUMS</a>
</authz:authorize> </div>
