reference to internal tomcat object (get # of sessions)

[chiuming]

Hi tomcat developers,
Please help me out on getting a reference to internal
tomcat object and find out total number sessions now
exist in tomcat instance (JVM).

The following code will return number of sessions in a
Context(web app) but not all the sessions in the whole
JVM (tomcat instance).  

For example:
if I call the class LocalMon in /admintool context:
/tomcat/webapps/admintool/WEB-INF/classes/LocalMon
then it will only report # of sessions in /admintool
web application.

Any way I can get the total number of sessions for all
web applications (context)? -OR-
How to call LocalMon in /admintool context but reports
session on other context(web app)?

My source file (class) return # of session and a (jsp)
is also attached.

public class LocalMon

  private ContextManager cm;
  private Request realRequest;
  private StandardManager _sessionMgr;
  
  public void init( HttpServletRequest request ){
    FacadeManager facadeM =
(FacadeManager)request.getAttribute(
FacadeManager.FACADE_ATTRIBUTE);
    realRequest = facadeM.getRealRequest(request);
    cm = realRequest.getContext().getContextManager();
    try{
        int manager_note = cm.getNoteId(
ContextManager.CONTAINER_NOTE,
"tomcat.standardManager" );
        _sessionMgr =
(StandardManager)realRequest.getContext().getContainer().getNote(manager_note);
    } catch( Exception ignored ){
    }
  }
  
  public boolean initialized(){
      return ( cm != null );
  }
  
  public String getNumSessions(){
      return( String.valueOf(
_sessionMgr.getSessions().size() ) );
  }
}
==============================================================

thanks a lot
