Re: Need Help w/ MVC and Database Question #2

[Chris Pratt]

In a nutshell, Struts is a framework that implements the MVC architecture.
It also comes with a couple of tag libraries, but those are just for
convenience, the framework is really what makes up Struts.  JSTL, on the
other hand, is a collection of Custom Tags that can be used with any
framework (or no framework at all, for that matter).

Funny you asked, I had the same question.. this is from the Taglibs mailing
list

My impression is that Struts will eventually accommodate the standard
taglib (JSTL) and integrate well with it.  The other taglibs in Jakarta
Taglibs are essentially just separate offerings from Struts, attempting to
address different needs (or similar needs from a different perspective).

Author, "JSP Standard Tag Library"  http://www.jstlbook.com
(coming this summer from Manning Publications)

This also:

Struts contains several different tag libraries. Some, like the 'logic'
taglib, will most likely be deprecated at some point, in favour of JSTL.
Others, such as the 'html' taglib, integrate more tightly with the Struts
framework, reducing the amount of work you have to do to hook your JSP pages
up to your ActionForm and Action instances.

If you're using Struts as your application framework, then it definitely
makes sense to use the Struts 'html' taglib. It also makes sense to look at
using JSTL for the less Struts related pieces of your pages. The two should
work together without problems.

Check out a new Wrox book, "JSP Site Design". It has some very clear
examples.

Re: Need Help w/ MVC and Database

The JOT Servlets framework supports MVC design approaches and includes a
JDBC ResultSet Iterator class.  The JOT documentation includes sample
source code for a JDBC database query Java Bean. Let me know if you need
help with that.

Re: Need Help w/ MVC and Database

[Duffey, Kevin]

 I would also recommend a very small simple MVC framework I built, called
Theseus, at www.theseus.org. Unfortanately, my job has taken up all my time
so I have not yet been able to complete the web site. I believe the basic
download is 23K or so, and it works very well. It has been used on many
professional sites (so I have heard anyways). I am available via email for
help should any be needed.

You have a method on a Java class executing... you can use JDBC or any
O/R mapping tool of your choosing.  It shouldn't be very confusing.
Just extract the data from the RowSet, build JavaBeans, and hand those
off as the model to the view layer.

It's definitely not a simple example, but the Maverick MVC framework
provides a *very* comprehensive sample J2EE application using a
combination of entity EJBs and direct JDBC access.  It's a wiki-like
image gallery which is actually being used in the real world.

The url for the sample application (the Punk Image Gallery) is
http://mav.sourceforge.net/pig.  I highly recommend that anyone who is
daunted by Struts (which is far more complicated than it should be for
what it does) should take a look at Maverick:
http://mav.sourceforge.net.

Good luck,

You've been reading the wrong books ;-) I describe an MVC architecture,
using a real database (behind a JavaBeans component) in my JSP book:

Need Help w/ MVC and Database

[Tom Kochanowicz]

Hello,

I am trying to do my first project with the MVC architecture (not using
struts yet). The examples I look at in books do not have a working example
that actually connects to "any" real database and they only show examples
loaded a very small amount of data. Does anyone have a "very simple" example
of a MVC actually retreiveing data from a database (any database) OR can
point me to a link that has an example. (yes I tried google).

Sincerely,

Tom K
