This method cannot throw an Exception or specifically not even a
ServletException. (Why?)
I want exceptions thrown here to propagate to my standard error handling &
jsp page.
How can I do that?
Do I use processException()? If so how does this work?

Doh!
Just found processPreprocess() that does seem to get called for EVERY

So I shall do my authentication there.

I have a List of subclasses that need to be iterated over and rendered in
jsp.
I notice that 'instanceof' is a reserved word in jstl, but has not been
implemented yet. So I now feel the need to write a tag.
On 1st glance I thought custom tag would be limited to Strings, but I see

Like session but attributes are removed when the response has been committed
in the request following the one they are added in.
Has anyone come up with a neat way of implementing this?

3) Only populate your value objects with the required columns in the first

A simple custom tag can be used to ignore it's body if an attribute is null.

you have do a 'finally' to ensure you close the connection/release it back

In the controller tier this is easy, get the connection in the

it.

I have subclassed the RequestProcessor and set a request attribute there, in

When I forward to a jsp page it is null.
Where may I be going wrong please?
Also is there a struts way to do:

I understand I can subclass DynaActionForm and register this in the
struts-config.
I can then populate my class with dynamic methods for any properties I like
& with type conversion, again in the struts-config.
I assume behind the scenes it is creating a new DynaClass sub class of my
subclass and
