[opencms-dev] OpenCMS authentication CLARIFICATION

[Bill Edwards]

Apologies for any confusion that my previous messages on this subject  
may have caused--please disregard them.  I have narrowed down my  
exception to line 1734 of OpenCmsCore.java (in OpenCMS 6.2.1):

             user = m_securityManager.readUser(contextInfo.getUserName 
());

Here is part of the stack backtrace:

java.lang.NullPointerException
	at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:1734)
	at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:701)
	at org.opencms.main.OpenCmsCore.initCmsObject(OpenCmsCore.java:726)
	at org.opencms.main.OpenCms.initCmsObject(OpenCms.java:551)
	at org.frontier.ecog.opencms.auth.OpenCmsAuth.<init> 
(OpenCmsAuth.java:42)

And here is my OpenCmsAuth class in full:

package org.frontier.ecog.opencms.auth;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.frontier.webapp.util.*;
import org.opencms.file.*;
import org.opencms.db.*;
import org.opencms.main.*;

public class OpenCmsAuth
{

   private CmsObject theCmsObject;

   public OpenCmsAuth(HttpServletRequest req,
                      HttpServletResponse resp,
                      String userName, String password)
   {
     super();
     try
     {
       FrontierLogUtil.logDebug("Creating CmsDefaultUsers");
       CmsDefaultUsers theDefaultUsers = new CmsDefaultUsers();

       FrontierLogUtil.logDebug("Getting guest username");
       String theGuestUser = theDefaultUsers.getUserGuest();
       FrontierLogUtil.logDebug ("theGuestUser = " + theGuestUser +  
", userName = " +
     		  userName + ", password = " + password);

       CmsObject theObject = OpenCms.initCmsObject (theGuestUser);

       String theLoggedInUser = theCmsObject.loginUser (userName,  
password);

       if (theLoggedInUser.equals(userName))
         FrontierLogUtil.logDebug("User " + userName + " logged in");
       else
         FrontierLogUtil.logDebug("Login failed for user " + userName);

     }
     catch (CmsException ce)
     {
       System.err.println("Caught CmsException: " + ce.getMessage());
     }

   }

}

Again, I am trying to run this from another Web application on the  
same Tomcat server to effect an automatic OpenCMS login.  My guess is  
that I am not accessing the OpenCMS application context properly.   
Again, apologies and thanks. -- Bill Edwards
