Logout-Problems in the Activiti Explorer

I succeeded in implementing a SSO-Login based on an IBM LTPA2-Token. Therefore, I implemented a methodpublic LoggedInUser authenticate(HttpServletRequest request,HttpServletResponse response)‍ in the DefaultLoginHander.java which gives back a LoggedInUser. The login is not the problem.The problem is

The Activiti Explorer code is ok. After several hours, I figured out that the problem was my own authenticate-method. I do not understand why but there, the user was cached anyway. Now, everything works.

This code is working for me. You have 8 errors. Line 85, Char 7, Line 86, Char 3, Line 88, Char 9 etc. Maybe you forgot to import some libs? Can you show the code on these 8 positions?

Thanks for your quick response Schnarr. please find below the code at above error position :

public void onRequestStart(HttpServletRequest request, HttpServletResponse response) {
    /*if (ExplorerApp.get().getLoggedInUser() != null && request.getSession(false) != null) {

      request.getSession().setAttribute(Constants.AUTHENTICATED_USER_ID, ExplorerApp.get().getLoggedInUser().getId());
    }*/
    if(logout){ //line 85,7
   Cookie[] cookies = request.getCookies(); //line 86,3
   if(cookies != null){
    for (Cookie cookie : cookies){         //line 88,9
     if(cookie.getName().equals("LtpaToken2")){
     Cookie newCookie = new Cookie("LtpaToken2", cookie.getValue()); //line (90,5), (90,28)
     newCookie.setPath("/");
     newCookie.setMaxAge(0);
     newCookie.setDomain("****");
     response.addCookie(newCookie);
     }
    }
   }
   logout = false;
}
}

public void onRequestEnd(HttpServletRequest request, HttpServletResponse response) {
    // Noting to do here
}

public LoggedInUser authenticate(HttpServletRequest request, HttpServletResponse response) {
    // No automatic authentication is used by default, always through credentials.
    return null;
}

public void logout(LoggedInUser userToLogout) {
    // Clear activiti authentication context
    Authentication.setAuthenticatedUserId(null);
    logout = true;                                                          //line (114,4)
}

Seems like you forgot to import some libs….
logout is a boolean variable that need to be declared: <code>private boolean logout = false;</code>
To use cookies, you need to import <code>import javax.servlet.http.Cookie;</code>

That should also be stated by your IDE. Are you using eclipse?

Thanks for the response. We are using eclipse but somehow it did not show any errors. Thanks again for helping out. Also, I have another query -

The purpose of trying to implement SSO for us is that we have a master website and want to embed Activiti in it. We don't want to show the login page and instead, want to pass the credentials via back-end, authenticate and display the default page. Is there a way we can do that by passing the credentials in the url iteself, so the login page can be skipped.

For example - If my url is - http://IP-Address:8082/activiti-explorer is there a way to pass credentials via something like - http://IP-Address:8082/activiti-explorer?user=username&pass=password.

Thanks
