hi there,
I've got working software on the server side and I would like (I have)
to create servlet-XML interface for it.
The questions are: How 'struts' is able to help me to do it faster ? Is
it able to support me at all ? Will I have something more from it ?
Thanks in advance

Hi all!
I'm defiantly new to the struts and taglibs so please bear with my questions:

EJBs come in two flavours (as opposed to flavors), session beans and entity
beans.
Session beans represent business logic and rules, entity beans represent a
row in the database.
The model that you'd use is to have Actions do the basic processing of form
elements into data beans (just regular
As far as struts 1.0, the Form bean is used only to redisplay
information to the jsp page. Typically the EJB might be loaded/unloaded in the
action class. If you search www.mail-archives.co,m Craig talked more about this in
detail.
In future version of struts this may be enhanced.

The way this is typically handled is to use an Action to populate the

I use EJBs without using copyProperties although it's a matter of

Actually, the plan is to build exactly this type of validation into Struts

The idea is to define your bean(s) in an XML file, and have the tool

You have not closed the link tag. After the %= display %, you need

Also, you might want to look into using the Struts logic:iterate tag
