Thanks for that.
You mentioned that a database connection should be in the init method.
I was wondering how this would be possible if you different users
logging in under different usernames and passwords, i.e. how to
initiate the different passwords and usernames.

I will try to answer this question a little bit more spefic:
in the init() method you should initialize global variables like
a database Connection. The init() method executes only onces
when the servlet is loaded.
Only the service() ( doGet(),doPost() ) methods are executed
for every user request.
After a time the WebServer managing Servlets will decide
to unload(destroy) your servlet.
In this case the destroy() method is invoked. So just before
the Servlet is Unloaded the destroy method is invoked.
So if you declared something in the init method like
Connection you should (have to) take care of it :
ex .
public void destroy(){
super.destroy();
Connection.close();
}
In other cases just use:
public void destroy(){
super.destroy();
}
That's all.
BUT in the past i didn't know anything about this destory() method.
So i didn't use it and my servlets where doing fine.
So if you want to be proud that your servlets are clean you should
use the destroy() method.
Best wishes,
Andras
