Hi all,

On the "http://jakarta.apache.org/struts/struts-logic.html"; site page, two
very interresting tags are presented : 'empty' and 'notEmpty'.

I have downloaded struts v1.0, but I just can't find them neither the
declaration in the "struts-logic.tld" file, nor the corresponding .class
files in "struts.jar".

Where are they ?

I absolutely need them ;-)

Thanks in advance,

Arnaud Chiaberge

Nested object reference inside of a nested iterator

[Minh Tran]

Hi,

could someone please take a look at this snippet of code and let me know
what i'm doing wrong?  I built this from snippets of facts that I found
throughout the messages on the list..  please let me know if any info is
incorrect..

Thanks,
Minh


In the following code.. I have several nested object.. I need to access..
on the highest level.. I have an orderForm which contains a collection of
shipSets..  I access each shipSet using the outside iterator.. now...
each shipSet contains.. a collection of lineItems...  so for each of the
shipSets..  I have another iterator.. that goes through all the lineItems
within the shipSet..   all of this works.. fine...  but here is the tricky
part... each of my lineItems.. contain a lineItemInfo which in turn has an
itemInfo object within the itemInfo object is "description"... which is
the value I want to get to...

assuming both iterator works(because they do.. and i've tested them..)...
lets look at the second iterator.. at this point.. I have a handle on each
lineItemInfo object for every iteration..  I would like to be able to do
   where I
can write out the description from within the itemInfo object held by the
lineItemInfo of the current iteration  this doesn't work... the server
always gives me back an error saying  "X Servlet Error: Cannot find bean
lineItemInfo.itemInfo in scope null".  

If you look a few lines above.. you will notice ""... which does work...  here...
quantity is in the lineItemInfo object..

I've seen many examples on this list of doing... something like ... is this faulse
information?

Thanks,
Minh

RE: How to customize the way Validation Error is display

[Minh Tran]

Well.. I think what I was looking for and what might help Brian is:

This queues two error messages, one for the "username" field and another for
the "password" field. To print all the messages together, simply place the
error tag anywhere in your JSP.
  
  
Or, you can place specific error messages at different locations

RE: Dynamically changing template and template source on a Master JSP page

[Minh Tran]

Hi Thinh.. yeah i've tried something like that.. using getAttribute and
setAttribute from the request object.. it seems to work.. but what I am most
concerned about is the ability for Struts to be able to function in terms of
form validation and prefill... if this happens.. since the Master jsp file
will be the one to be routed to all the time..

Let me know if you have any thoughts.

Thanks,
Minh

[Minh Tran]

Does anyone know how to control and customize the way the validation error
is display when when fills out incorrect form information?

Dynamically changing template and template source on a Master JSP page

[Minh Tran]

Has anyone ever tried to do this?

I would like to have a master JSP page this looks something like this:

<%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %>









but be able to dynamically change the template and or the template:put
content source to something else...

I thought about using scriptlets to insert the dynamic source.. but that
doesn't work..

Please let me know if you've have any ideas.. 

Thanks,
Minh

Bug in Struts Template

[Minh Tran]

Hi,

can someone please let me know if there is a known bug with the struts
template libs.. on how it produces html code...  notice in the html output
below has the  structure defined in the template at the end with all
of the dynamic data printed ahead of it...  there is definitely something
wrong.. the data should be within the template structure defined..

I know this has to be a known bug.. since it's too big of a bug to not be
known...

also.. could you please let me know how to fix it..

Thanks,
Minh

This example application is based on http://www.javaworld.com/javaworld/jw-09-2000/jw-0915-jspweb_p.html";>U
sing JSP templates to encapsulate Webpage layout and encourage modular
design by David Geary. Follow that link for the full article, which also
covers using role-based and nested templates. The template classes described
in the Java World article were the basis for those included with Struts
1.0.
Introduction
Window toolkits typically provide a layout mechanism
that positions widgets in a container; for example, AWT and Swing have
layout managers, whereas VisualWorks Smalltalk has wrappers.
Because layout undergoes many changes over the course
of development, it's important to encapsulate that functionality so layout
can be modified with minimal impact to the rest of the application. In fact,
layout managers are an example of one of the tenets of object-oriented
design: encapsulate the concept that varies, which is also a fundamental
theme for many design patterns.
JSP does not provide direct support for encapsulating
layout, so web pages with identical formats usually replicate layout code;
for example, A Web Page Layout shows a web page containing sections
for a header, footer, sidebar, and main content.
The layout of the page shown in A Web Page
Layout is implemented with HTML table tags, as listed in Including
Content.

Including Content




 


In Including Content, content is included with
 which allows content to vary without modifying HTML;
however, because the layout is hardcoded, layout changes require
modifications to the page. If a website has many pages with identical
formats, even simple layout changes require modifications to all of the
pages.
Using A Template


<%@ taglib URI='/WEB-INF/struts-template.tld' prefix='template' %>


   
   
   
   
   


To minimize the impact of layout changes, a mechanism
is needed for dynamically including layout in addition to content. That way,
both layout and content can be changed without modifying files that use
them. For large websites that have many pages with identical formats, such a
mechanism is valuable because it localizes changes to layout. That mechanism
is JSP templates.

Struts MVC Framework Vs. XSLT Tranformation for Web UI Handling

[Minh Tran]

I'm pretty new to struts.. so I would appreciate if anyone can share their
experiences with Struts and XSLT Transformation for the Web UI generation.
I am starting a project pretty soon.. and the project lead is pushing to do
a Servlet-XSLT model where XML + XSL will be transformed to HTML for the UI.
I am currently pushing for Struts.. but I need some more ammo so that I can
push struts as the framework for us.

Thanks,
Minh Tran
