This may seem to simplistic, but you could do a search for whichever
method you call to open a connection and then do a search for
connection.close() (or whatever you named the variable) and see if the

You could add a 'state' property to the form, that the first action can
set to 'STARTED' and the last action can set to 'FINISHED' or something
like that, then in your reset() method you could do something like:
reset()
{
if(state == Constants.FINISHED)
{
// reset all vars

You can forcibly remove it as the last step in your last action before
sending the user to a success page:
request.getSession().setAttribute(formName, null);
where formName is the same name you gave the bean in your

It depends on how you load the elements. If you are creating the smaller
objects by first loading the full objects, then just save the time and use
the full ones.
If however you are loading the DisplayObjects directly via a Hibernate query
of course that will be magnitudes smaller.
I second this especially if you are doing Struts. MyEclipse offers wizards,
visual flow navigation and manipulation for your Struts apps which is quite
nice and of course JSP autocomplete, debugging, taglib autocomplete, xml

This can definately get confusing if you are just thrown into the mix.
Tomcat 5 is definately the right way to go, its faster, more stable and
supports newer specs. Struts, IIRC, is designed to only need the Servlet 2.2
and JSP 1.0 or 1.1 spec, it was meant to be super-compatible, soyou
acceptable. And it wasn't a monstrous server either (Dual
P2-550's with 1G RAM and a SCSI array internally).
So, I wouldn't be too concerned with the size of your struts-config, unless
someone else has reason to disagree. A couple of K wouldn't concern me.
