about the SSO

[Migrated From Jforum.net]

I am a fresher of sso,i have read the http://www.jforum.net/confluence/display/integration/Overview.
Then i make a login page of login.asp.I store the username in the cookie:
Cookie cookie = new Cookie("JforumSSO", username);
response.encodeRedirectURL("http://222.201.186.143:8083/jforum/").

I make a MyUserSSo.java.

In the SystemGlobals.properties of jfourm:
commented : #sso.implementation = net.jforum.sso.RemoteUserSSO
added : sso.implementation = net.jforum.sso.MyUserSSO

commented : #authentication.type = default
added : authentication.type=sso
sso.password.attribute = password
sso.email.attribute = email
sso.default.email = sso@user
sso.default.password = sso
sso.redirect =http://192.168.1.18:8080/login.jsp
but when i connect the jfourm after i login the web.The error is like this:


Expression templateName is undefined on line 5, column 14 in exception.html. The problematic instruction: ---------- ==> ${templateName} [on line 5, column 12 in exception.html] in include "${templateName}/message.htm" [on line 5, column 1 in exception.html] ---------- Java backtrace for programmers: ---------- freemarker.core.InvalidReferenceException: Expression templateName is undefined on line 5, column 14 in exception.html. at
-----------------------------------------

What is the problem? How can i solve this?
Thank you your help.

Look at the tomcat logs. The real error is in there.

If you want, you can attach it here, so we can take a look.

Just a note on the MyUserSSO.java example from wiki, the code provided doesn't work with version 2.1.6 source code.
That code contains some errors: reference to JForumContext instead of JForumExecutionContext, call to an undefined addCookie with age, redirect to login page not working.
Here's a slightly modified version (with single cookie), that may help someone to better understand the "simplified sso" cookie mechanism.

package net.jforum.sso;
 
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import net.jforum.ActionServletRequest;
import net.jforum.ControllerUtils;
import net.jforum.JForumExecutionContext;
import net.jforum.entities.UserSession;
import net.jforum.util.preferences.ConfigKeys;
import net.jforum.util.preferences.SystemGlobals;
import org.apache.log4j.Logger;
 
 public class MyUserSSO implements SSO {         

     static final Logger  logger = Logger.getLogger(MyUserSSO.class.getName()); 
     
     public String authenticateUser(ActionServletRequest request) { 

          // sso pool apps login cookie, contain logged username
    	 Cookie myCookie = ControllerUtils.getCookie("auto-login");
           
         String username=null;          
         if (myCookie ==null){
             JForumExecutionContext.setRedirect(SystemGlobals.getValue(ConfigKeys.SSO_REDIRECT));
             return null; // no cookie found
         }else{
             username=(String)myCookie.getValue();  
             if (username.equals(""))
                JForumExecutionContext.setRedirect(SystemGlobals.getValue(ConfigKeys.SSO_REDIRECT));
         }        
         return username; // jforum username
     }
      
     public boolean isSessionValid(UserSession userSession, HttpServletRequest request) {
         String      remoteUser  = null;
           
         Cookie SSOCookie = ControllerUtils.getCookie("auto-login"); // my app login cookie
         
         if (SSOCookie != null) remoteUser = SSOCookie.getValue(); //  jforum username

         if(remoteUser == null){
            JForumExecutionContext.setRedirect(SystemGlobals.getValue(ConfigKeys.SSO_REDIRECT));
             return false;
         }else if (remoteUser.equals("")){ 
            JForumExecutionContext.setRedirect(SystemGlobals.getValue(ConfigKeys.SSO_REDIRECT));
             return false;
             // user has since logged in
         } else if(remoteUser != null && 
             userSession.getUserId() == SystemGlobals.getIntValue(ConfigKeys.ANONYMOUS_USER_ID)) {
             return false;             
         // user has changed user
         } else if(remoteUser != null && !remoteUser.equals(userSession.getUsername())) {
             return false;
         }
         return true; // sso pool apps user and forum user the same
     }
 }

I don't know which compiler/ide can produce an error message like that, but the sentence above may be linked to the real error.
For compiling successfully you must preserve the package/directory structure, if you have all the imported class (different class from different package) in the same dir you'll surely get some class not found error at compile time.
What i suggest is to extract somewhere the full source tree (get it from here http://www.jforum.net/download-source.jsp) import all the source in a new project with your ide (eclipse,netbeans,ecc...) add the new class and compile all the sources.
Hope this helps.

Hi Jules thanks for the reply! Sorry to ask another question but then how would the JSP page code look like? would it call the methods in the complied class MyUserSSO ?

Do you have a sample code?

Sorry for this request as i really need some examples to follow for my project.

Thanks!

I've got Eclipse v3.2.2
I'm using j2sdk1.4.2_12
I've gotten the source from the downloadable zip.
I've gotten the missing 5 .jar files from the CVS.

I've gotten to the point where the existing stuff will rebuild without errors - just 90 warnings.

I've created a MyUserSSO.java using the code in this thread.

I show an import that cannot be resolved:

import net.jforum.ActionServletRequest;

I find this file in the CVS only by viewing dead files.

Again, please, does ANYONE have a working version of simple cookie-based SSO for JForum v2.1.7?

Please?

I'll trade you for some Oracle consulting time. Really!

Thanks,
Jennifer
