RE: processPreprocess

[Kiss, Tibor (Contractor)]

Yeah, I had a look at both stxx and StrutsCX.
However, both of these were designed for Struts1.0, have no support for
DynaForms, Validator and Tiles, all of which are being used in our app.
STXX: It modifies the 1.0 ActionServlet, and is tightly coupled to Struts
1.0.
StrutsCX: IMHO, much better design, however there are some problems with
internationalisation. (eg.: all of your messageresources are written to all
of your xml files. We have more than 1000 messages, for 5 languages each...)


I have written a new RequestProcessor, which allows you to freely mix jsp
and xsl. DynaForms are supported.
Now I am trying to get Validator running, and then later a modified version
of Tiles as well.

My plan:
I am using Saxon as a Transformer, and plan to use some Saxon extension
classes (xsl taglib??? :) ) to handle internationalisation and security
issues.

And your filter should intercept unathorized access, forward to a login
page, authorize/register the user, and then redirect him, to the page he was
before.

I did not use Struts for the login/register thing, it is completely handled
by the filter.

Betreff: Best way to accomplish interstitial logins?


Is there a way to accomplish interstitial user logins using Struts that
doesn't seem to defeat part of the reason for using Struts in the first
place?

By "interstitial", I mean situations where users arrive on the site and can
roam & act freely UNTIL they try to do something that requires a valid
login. At that point, they'd be shown a login screen, cycled through it a
few times if they enter an invalid username or password, then continue with
their original request as though nothing had happened to interrupt it.
Ideally, even new user registration could take place as an interstitial
activity.

For a concrete example, suppose a user visits a career site. He browses jobs
for a while, then finds one that looks interesting and clicks "apply
online". At that point, the Action-extending class realizes that he needs to
be logged in to continue, so it takes a sidetrip to log him in, or register
him as a new user, before transparently finishing the original activity as
though the interruption in the middle (to login or register) had never
happened.

I've implemented something like that in the past using Struts 1.0, but ended
up feeling like I was trying to hammer a square peg into a round hole.

Basically, I created an abstract FormBean that encapsulated the username,
password, and submit button, then used it as the superclass of every other
FormBean used by the application. The general idea being that every form
then became a potential login form, with the login elements normally not
displayed, but ONLY the login elements displayed at interstial login time.

actions that didn't require that the user be authenticated were mapped to
classes that extended the Struts Action class. Actions that DID require
authentication extended the AuthenticatedUserAction class, and their
perform(*) method checked to make sure the user was logged in. If not, it
tried to log in the user (if a username and password were submitted with the
last form submission) and returned the actionmapping to the login page if
the user couldn't be logged in. If yes, it returned the result of
performLoggedInUserAction(*), which served the same purpose as perform(*) in
unprotected pages.

The brick wall came from the requirement that Struts forms specify a
*compile-time* value for the form's action. Since the request that resulted
in the login form's display could have been to just about ANY plausible
mapped path in the webapp, and ultimately the form had to submit to that
exact same action in order to transparently complete the action, there
seemed to be only two work-arounds:

* create a login page for every single mapped Action in the site. Ouch.

* do everything through one ungodly huge monolithic Action

Creating dozens of login pages that were identical except their action
parameter was a pain, but doing everything through a single monolithic
action seemed even worse architecturally, because it seemed to defeat the
purpose of mapping actions to forwards in struts-config.xml instead of
hardcoding them in the controller.

At the time, I took advantage of Struts' open-source nature to create a
Third alternative: I hacked Struts to permit struts forms with null action
parameters. At launch time, it stored the action to which the form was
submitted in request context. A few milliseconds later, when the form was
being rendered, if the rendering class discovered that the form's action was
null, it would silently retrieve the action from request context and  "fill
in the blank", so to speak. It worked, but it kind of bothered me that
Struts' designers probably had a good reason for not allowing that practice,
since hacking the appropriate classes to allow it took all of maybe an hour
and seemed like too easy of a solution to not have some Good Reason for its
absence.

So... what's the Right Way to implement interstitial logins? Is there
possibly some new feature that came out with 1.1 that solves this problem?

Just a thougth

OR mapping has been a THING for the last 10 years...and I do not think,
anybody will provide a good generic solution. Ever.
.NET will come, and stay. Java too. But I think (got the feeling in the gut)
that IBM will take it over in a few years.

Well, if I can comment: Struts is an excellent MVC implementation.
Ok, people realize it is a very important notion when developping
applications. This skill will probably be REQUIRED in 6-8 months.

We, fortunately, joined the gravy train soon enough and now
have some Struts knowledge we can sell. But in 6 months, all the 
script kiddies will be Struts warlords (PHP5 roXor :-)

Developping other skills is still a major effort.
I consider OR mapping and JUnit testing to be 
the probable NBT (next big things) for 2003. 
What's your opinion?

Ps: ok, JUnit is already a big thing :-)

Hi,
When deploying an application you generally create an ejb jar, an ear
and a
war file
the ejb containing all ejb, the .war containing all the java,jsp taglibs
and
web-inf.

My assumption is that this means the ejb.jar does not know the
application.resources file.
(since it cannot see the web-inf/classes) am i right ? 

What would you do if i need to use properties in the ejb's ? Do i write
a
utility class reading
another property file ? Or can i use MessageResources and the factory
for
it, reading a propertyfile.

AW: [OT] web site idea (was Value of Struts)

[Kiss, Tibor (Contractor)]

I do not know, how things are on the other side of the drink (USA) but here
in Europe more and more companies do go for open-source. (In 2002 I have
seen one project on Weblogic [with Struts] and a multiple of them on JBoss.)
The only place, where OSS is behind are databases. IMHO.

Plus, companies are installing Linux like crazy all over the place. :)

Does Struts have any commercial alternative?

Many big names use a lot of OSS. (IBM, Oracle, Sun)

AW: Packaging struts business logic and action classes

1 BO
Are the classes, that represent entities in the business domain. (NOT EJBs,
although BO persistence can be through EJBs.)

2 DAO
The Persistence Objects for BOs. (In theory, if you are using EJBs, they
serve as DAOs, although, this explanation violates the strict definition of
DAO, and I might get flamed...)

3 VO
== BO, although VOs can be assembled in a way, which does not reflect
Business Entities any more.

4 DTO

packaging? Depends...

I would put business logic in a separate layer (package) and invoke business
logic delegate classes from the action classes. This decouples struts from
your logic.
Currently, we have a project, with the following structure:

struts action package
business delegate package
session bean package
entity bean package

eg.:

How you name the package, is actually up to you. Just do not name it java.
or javax. or sun.
(and of course, com.ms., and all those copyrighted thingies...)

What is the general way of packaging a struts application?
like if my companyname is www.companyname.neti will probably have an

I would like my business logic to be independent from the struts specific

 I also know the package should start with
net.companyname.applicationname.

processPreprocess

[Kiss, Tibor (Contractor)]

Hi!

We are using Struts beta2 in a production environment, under Weblogic6.1.

We are trying to modify Struts beta 3 to use XML/XSLT internally instead of
JSPs. (As output should not only be HTML.)
Therefore, we subclassed RequestProcessor, to invoke an XML bean
serialization mechanism and XSLT transformer.
However, the signature of the processPreprocess method does not allow me to
throw Exceptions.

I would suggest adding a throws IOException, ServletException to the
signature, so one could wrap other exceptrions.

Cheers
