Seraph sso

[Firas hammami]

Hi all 

I'm trying to build a custom authenticator using seraph, in /atlassian-jira/WEB-INF/classes I puted this class :

package com.mycompany.seraph;

import javax.servlet.http.HttpServletRequest;
package com.mycompany.seraph;

import org.apache.log4j.Category;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.atlassian.seraph.auth.DefaultAuthenticator;

import java.security.Principal;

public class SSOnCookie
{
public static SSOnCookie getSSOCookie(HttpServletRequest request)
{
// ...
}

public boolean isExpired()
{
// ...
}

/** Return the username implied by the cookie in the request. */
public String getLoginId()
{
// ...
}
}
/**
* Extension of DefaultAuthenticator that uses third-party code to determine if a user is logged in,
* given a HTTPRequest object.
* Third-party code will typically check for the existence of a special cookie.
*
* In SSO scenarios where this authenticator is used, one typically configures Seraph to use an external login page
* as well:
*
* <init-param>
* <param-name>login.url</param-name>
* <param-value>http://mycompany.com/globallogin?target=${originalurl}</param-value>
* </init-param>
*

*
*/
public class SSOAuthenticator extends DefaultAuthenticator
{

private static final Category log = Category.getInstance(SSOAuthenticator.class);

public Principal getUser(HttpServletRequest request, HttpServletResponse response)
{
Principal user = null;

try
{
if(request.getSession() != null && request.getSession().getAttribute(DefaultAuthenticator.LOGGED_IN_KEY) != null)
{
log.info("Session found; user already logged in");
user = (Principal) request.getSession().getAttribute(DefaultAuthenticator.LOGGED_IN_KEY);
}
else
{
SSOnCookie ssoCookie = SSOnCookie.getSSOCookie(request);
log.info("Got SSOnCookie "+ssoCookie);

if (ssoCookie != null && !ssoCookie.isExpired())
{ // Seamless login from intranet
log.info("Trying seamless Single Sign-on...");
String username = ssoCookie.getLoginId();
System.out.println("Got username = " + username);
if (username != null)
{
user = getUser(username);
log.info("Logged in via SSO, with User "+user);
request.getSession().setAttribute(DefaultAuthenticator.LOGGED_IN_KEY, user);
request.getSession().setAttribute(DefaultAuthenticator.LOGGED_OUT_KEY, null);
}
}
else
{
log.info("SSOCookie is null; redirecting");
//user was not found, or not currently valid
return null;
}
}
}
catch (Exception e) // catch class cast exceptions
{
log.warn("Exception: " + e, e);
}
return user;
}

}

after that I edited seraph file like that  <authenticator class="SSOAuthenticator" />  SSOAuthenticator is the name of my class 

I got this error  org.apache.catalina.startup.ContextConfig.processAnnotationsWebResource Unable to process web resource [/WEB-INF/classes/SSOAuthenticator.class] for annotations 

have you any idea please?
