Which is better?
Hi,
I have these following code:
BeanOne {
dbCon();
getX();
getY();
close();
}
BeanX {
dbCon();
getX();
close();
}
BeanY {
dbCon();
getY();
close();
}
-
- In BeanOne, is that mean there's only one connection to DB regardless of
howmany times bean called (using get property in jsp)?
- Which is better, using one bean or two?
- When is the right time we need to cleanup connection (ie. using st.close() )?
- Thanks!

Container automaticaly rewite links.
Hi,

but when i run in container, in browser it says something like
"/index.jsp;jsessionid=qweutyqwte?par=value" which means the container was
rewrite *all* url.
in fact, im not using any response.encodeURL("index.jsp") and my browser

It's on the same directory, if so its hould give 404 instead of 500.
I thinks it because of "error scoping", for eaxample it work when i try to
getString("not_valid_colum"), but not other "serious" error.
Anyone knows the "scope"?
