Somebody wrote a DataListHandler pattern to handle large result sets.

All the solutions mentioned so far are good, simple, and easy to implement.
But they don't scale: what if your ResultSet doesn't fit in memory?

Try to include in your JSP:
head
html:base/
/head
That should fix your relative links.

Use a cursor. MySQL does it with:
SELECT name FROM customers LIMIT 5, 10
Yes, it's optimized.

All databases can do that, maybe differently.

How about making your bean return a reversed collection?
Collections.reverse() is your friend.

Have you tried declaring your property as an array of strings?
private String propertyName[];
public String[] getPropertyName() { ... }
public void setPropertyName(String[] propertyName) { ... }
It may just work. In general I've found Struts to be amazingly flexible with
properties and their
If the only thing you need to do is increment a variable, I think your way
is still the best way. But usually people increment counters to access
arrays or lists. In that case, if you have a list, an array, or any

Hi Stephen,
I read your comments with interest.
What alternatives are there to session scoped beans? One could use hidden
variables to pass along simple data items, but that becomes awkward for
storing lots of fields, or whole objects, as you have to unpack them in
the
JSP and pack them
You could also iterate over a collection of your company numbers (if you
have many).
E.g. below I'm iterating over a collection of platforms (I previously
prepared a collection named platforms). The radio buttons let me choose
one platform; this is equivalent to a pop-up menu widget.
