hi
i need some help. my problem is the following:
i use a class caching files whilch I refer to in several servlets.
this one should be a singleton. to achive this, it is implemented like:
public class filecache{
private static filecache myself = null;
private filecache()
{// do some init stuff
}
public filecache getInstance()
{
if (myself==null)
{
myself=new filecache();
System.err.println("I have been initialized !");
}
return myself;
}
...
}
and in the servlets
public class testservlet
{
private static filecache fc = null;
public void init (ServletConfig c) throws ServletException
{
super.init(c);
fc=filecache.getInstance();
}
...
}
Unfortunatly JServ obviously initializes one filecache now per
Servlet-Zone !?
in fact I see as many "I have been initialized !" as
servlet-zones are defined.... hmmmm....
how to overcome this ?! i just want to have one filecache created per
VM.
hints ?!
MfG Uwe Schaefer
