Hi :-) I did a simple test :
* enviroment: jakarta-tomcat-4.0-b1(stand alone) on windows.
* testing code:
...
public void service(...){
HttpSession session = req.getSession(false);
if(session==null) session = req.getSession(true);
System.out.println( "session.getId()="+session.getId() );
System.out.println( "Thread.currentThread().getClass().getName()="+
Thread.currentThread().getClass().getName() );
System.out.println( "Thread.currentThread().getName()="+
Thread.currentThread().getName() );
System.out.println( "Thread.currentThread().hashCode()="+
Thread.currentThread().hashCode() );
System.out.println( "\n" );
try{
Thread.currentThread().sleep(5000);
}catch(Exception e){ System.out.println( "in Thread sleep, e="+e ); }
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<html><body>");
out.println("in service, ok, haha");
out.println("</body></html>");
out.close();
}
...
* analyzing:
- I use two instances of NN4.7 to test it:
one NN4.7 instances which is start by "double-click from desktop :-) "
another NN4.7 instances which is started from the "File/New/Navigator
Window of the first one"
- the following are same in two request from two NN4.7 instances:
session.getId()
and
Thread.currentThread().getClass().getName()
and
Thread.currentThread().getName()
- sometimes the following are same in two request from two NN4.7
instances, but sometimes they are not same:
Thread.currentThread().getName() );
and
Thread.currentThread().hashCode() );
I think there is a "thread pool": because if I request MySevlet from the
2
NN4.7 instances with "interval <5s", I will get two different hashCodes
of the thread. But if "interval >5s", I often/always get the same
hashCode
of the thread.
- so I just guess perhaps we can Not use "HttpSession + Thread" to identify
a special session( several instances of one_browser <-> one_wepapp).
