Hi :-) I suggest you make a object witch implements
javax.servlet.http.HttpSessionBindingListener, and put object into a session
by "setAttibute(...)", then:
- when that object is "bounded" into session, "valueBound(...) will be
called
by container
- when the session is timeout/inValidate(...), that object will be
"unbounded",
then "valueUnbound(...) will be called by container
the following is a sample code from Servlet-List:
class CleanUp implements HttpSessionBindingListener{
private String name;
public CleanUp(String name){
this.name = name;
}
public void valueBound(HttpSessionBindingEvent evt){
System.out.println("in CleanUp, valueBound..., name="+name);
}
public void valueUnbound(HttpSessionBindingEvent evt){
System.out.println("in CleanUp, valueUnBound..., name="+name);
}
}
in MyServlet:
...
session.setAttribute( "Cleaner", new CleanUp(...) );
...
*
- if CleanUp.class is in WEB-INF/classes or in a jar file in WEB-INF/lib,
it will be loaded by WebappClassloader
- if CleanUp.class is in TOMCAT_HOME/classes or in a jar file in
TOMCAT_HOME/lib, it will be loaded by SharedClassloader
