If you don't wnat to be tied to the DynaBean api either you could defin your
own custom DTO interface that defines the data that your model layer
requires.
then you could have your ActionForm implement your custom interface. Then
you could just pass the action forms into the layer as the custom
agree that seems like a good way to approach it :)

Your action could write the html from your DTO directly to the response,
without the need to forward to a JSP.
this would go along the lines of:
snip
inStream = docLib.getDataStream();
ByteArrayOutputStream out =new ByteArrayOutputStream();
byte[] buf = new byte[4096];
int i = -1;
Try putting the poolman.xml in the WEB-INF/classes folder

Try this (or something close) in your Action code :

Looks like the initialisation of your actionservlet is throwing a NPE.

IMHO the DB should never be accessed by anything in the JSP itself, Tag or
otherwise. I believe that one of the purposes of having actions is to
enable delegation of things like DB access to specialised layers which can
then be pluggable. Also, using actions allows processing to be wrapped

Sounds like the document/context root on the server you deployed it on is

back to
Alexander is right you can forward to another action in this way.

parameters for the action you are forwarding to and you may find yourself

One way would be to create an abstract layer underneath the action layer
that defines an abstract method similar to the perform() method. Then you
could 'wrap' processing around the call the the abstract method which your
