Thank you, I switched from a member variable to the datastore and it
solved the problem.
There is one thing that is not clear yet:
I've overridden the init() and destroy() methods of the servlet and
added a log printout in each one of them. I can see that the init()
method is called from time to time, but I never get the destroy()
printout.
@Override
public void destroy(){
log("Servlet Destroy after " + counter + " times");
}
@Override
public void init(){
log("servlet init");
}
