Re: Book Opinions

[Vernon Wu]

Nat,

I am thinking about walking the opposite direction as you do. After playing about the 
Pet Market from Macromedia MX, I 
wish my Java Web application have the degree of rich UI. You might be able to tell me 
how to add the MX on the top 
of Struts, or similar MVC Java web application: replaying JSP, the "V" with MX, also 
the "V" with least possible work.

I don't know any Struts books out there. But you shall be able to find tons of on-line 
tutorial in the subject. Remember 
"Google is yor friend". One book I can recommend is "Advanced JaveServer Pages" by 
David Geary. The frameworks 
introduced in the book are very similar with those in Struts, including MVC one.

If you want to write back, please send to my email address.

Regards,

Vernon

Book Opinions

[Nat Papovich]

Hello All -

I'm a recent addition to this list, while I begin learning Struts. Not only am I
beginning to learn Struts, I'm beginning to learn all things Java.

I come from a ColdFusion/Fusebox background, but as a "leader" in that
community, I have secretly wanted more structure from a framework, along with
transitioning to a more "robust" web language. Fusebox also does an incomplete,
kludgy job dealing with MVC, of which I am fond.

I'm quickly getting knee-deep in many resources, and am burning through my old
"to be read" book collection of OO programming and JSP (working on Bruce Eckel's
Thinking in Java now). I consider myself to be well-versed in OO, very
comfortable with structured programming (structured meaning well-designed in
this case, not opposed to OO), but being a huge proponent of ColdFusion's
leading framework, I recognize the importance of starting off on the right foot
in my J2EE adventure (and think Struts is that right foot).

That exhaustive background was meant to help you fine folks make book
recommendations for me. I have bookmarked and visit some of the excellent online
resources for Struts and Java, but I'm the kind of guy who likes to spend money,
have something bound, with a glossy cover, sitting on my desk - it's like a
security blanket to me.

So of the apparently excellent titles either currently available or
soon-to-be-released, which one should I start with? Undoubtedly, I will acquire
another, and another, but for now... ?

Thanks,
NAT

[ANNOUNCE] SVT 0.5.0-beta released

[Shinya Kasatani]

Hello,

I am pleased to announce that I have released a first version of SVT
(Struts Validation Toolkit).
SVT is a form validation framework for Struts.

You can write a simple validating code in Java, rather than
writing validation.xml files.

For example, if the form bean has properties "name" and "age",
both is required, and "age" must be a number,
the validation code looks like this:

public class InputForm extends ActionForm {


public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {

Validator v = new Validator(getServlet(), this, mapping.getName());
v.validate("name", Rules.required());
v.validate("age", new Rule[] { Rules.required(), Rules.number() });
return v.getErrors();
}
}

You can get it from http://svt.sourceforge.net/

If you have any comments please write to [EMAIL PROTECTED]

Re: access ApplicationResource from ActionForm

[Arion Yu]

Hi all,

for ApplicationResource, check ActionForm.getServlet.getResources
for the locale, however, the variable is protected and you have no way 
to access it in this way.

One of the way to accomplish it is pre-create the form in Action (before 
going to JSP) and set the locale during the Action phase.


Would there be other way like adding a locale variable in ActionForm? Or 
a public getLocale in ActionServlet ?

Arion

P.S. my version is 1.0.2

Hi All,

My ActionForm is populating a drop-down list ( LabelvalueBean's ) and I want
to say "- None -" for a none-selection .. and want it to be i18n.  So, can I
access the ApplicationResource to retrieve that 'None'.  If so, how?

Is this the best idea?

Yes, on successful completion,  PrepareListBookAction.perform() ends with

If you are getting a blank page, there is most likely something wrong

I am incredibly stuck with the concept of how to code an action that is not

Here is a simple example showing one way to deal with this type of 
thing. There are no doubt lots of other ways to handle this.

Use case: library search.  User page flow: main menu -> search input 
page (bookSearch.jsp) -> search results page (listBook.jsp).  The search 
input page needs to be pre-populated with a list of currently defined 
subjects.

Struts processing flow: main menu -> search input pre-populate action 
(PrepareListBookAction) -> search input page (bookSearch.jsp) -> search 
processing action (ListBookAction) -> search results page (booklist.jsp).

In struts-config:



	name="bookSearchForm"
	type="com.steitz.library.PrepareListBookAction"
validate="false"
	scope="request">
	




	name="bookSearchForm"
	type="com.steitz.library.ListBookAction"
scope="request"
	input="/a/bookSearch.jsp"
	validate="true">
	


In the main menu:



(here "index.find" = "Find a Book".)

PrepareListBookAction retrieves the list of currently defined subjects 
and sets a property of the (automatically created) BookSearchForm for 
the book search input form (bookSearch.jsp) to use.

The key concept is that instead of linking/forwarding to the input jsp 
directly, you link/forward to the pre-population action and then have 
the pre-population action set up the form bean and then forward to the 
input jsp.

Hope this helps,

Phil








I do understand how to actually create a bean manually and put in in the scope. I 
don't understand how to set up a generic preload action for a given JSP/ActionForm, 
and what the config should look like.

Again, any help much appreciated.

In fact, the best practice is to always preface a page with an action.  You end
up with actions that prepare information for a page, and actions which process
information for a page.  The actions which process the page information will
always have had the form bean created before you get to the action.  However,
the actions which prepare the page information may have to manually create the
form bean and put it into the appropriate scope.

Note that the welcome page for an application would normally be something like
"index.jsp", which does nothing but forward to an action to start the
application.  You can't preface the welcome page with an action, but you can
make it do nothing but go to an action to prepare the real first page.

Look at the source code for the "example" a

[BOOK ANN] Struts: Practical Guide now available

[Sue Spielman]

Hi, Everyone:

I'm very pleased to announce that...

The Struts Framework: Practical Guide for Java Programmers (Morgan-Kaufmann) 
is now available.

The Struts Framework: Practical Guide for Java Programmers is written for 
Java programmers who need to understand, build, and deploy Struts 
applications. It provides the systematic exploration required by newcomers 
as well as the step-by-step instruction for more experienced readers eager 
to exploit Struts to the fullest. Devoted to the latest version of the 
framework (v1.1) and vividly illustrated with a thorough sample application 
throughout, this book is an essential resource for all programmers who want 
to be part of the next stage in the evolution of the web.

Features
• Hard-to-find, practical coverage from a highly visible figure in the Java 
development world.
• Reviews all the technologies comprising Struts, including JavaServer 
Pages, Servlets, XML, Custom Tags, and web and application servers.
• Teaches readers the development practices—including design, debugging, 
internationalization, and implementation—essential to Struts development.
· Provides downloadable sample code and data for use in a Struts-based 
database application via a companion web site.

What readers are saying:
I heartily endorse this book. Ever since an early copy of Sue's manuscript 
hit my desk, it has not left my side and is now well thumbed and gathering 
coffee stains from regular use.
—Simon Chappell, Java Programming Specialist with a Fortune 100 company

Sue Spielman launches the aspiring Java J2EE programmer on an exciting 
exploration of Struts-based MVC architecture and applies this knowledge in 
creating a state-of-the-art web application. No 21st Century web software 
engineering library is complete without this important book. 
—David McClure, Internet Technology Group, Fidelity Investments

I've used this book to jump start my Struts-based application development. I 
especially like the "Struts Development Cycle" that describes best practices 
for designing, implementing, and deploying a Struts project. This book has 
valuable insights that you won't find anywhere else.
—Tom Marrs, Senior Architect, Distributed Computing Solutions, Inc.


I hope this book is an asset to the Struts developer community and I'll look 
forward to hearing your feedback. You can order your copy at

I'm not sure that's the issue, because the session.getAttribute returned a correct 
ArrayList object employeeList and the for loop works fine.

Read the API documentation for the "present" tag.  You'll find it says this
about the "name" attribute:

  Checks for the existence of a JSP bean, in any scope, with the specified name.

That means the key for the object in the table has to have that name.  In your
"logic:present" tag, you've referenced the name "employeeList", but you put it
into the table with a name of "com.xyz.key.USER".

RE: return false

[Tuan H. Le]

Hi David,

Thanks for your response! 

IConstants.USER_EMPLOYEE_LIST_KEY is a string of value "com.xyz.key.USER". I'm not 
sure that's the issue, because the session.getAttribute returned a correct ArrayList 
object employeeList and the for loop works fine.

Any ideas?

Thanks,
Tuan

Nope.  It's not.  There are things which can be used on top of Struts 
for this though - at least, I believe there are.  It occurs to me I've 
seen a couple of posts about such a thing recently, but I can't remember 
it's name - and certainly can't speak to how effective it/they are.

Is it really that hard to iterate over a collection and build a table 
though?

RE: i18n messages in javascript js file

[James Mitchell]

Have you taken a look at using the validator (its part of core struts now)?

By using this validation framework, you can add both client side and server
side validations to your web application.

You can get up to speed by reading the docs or (as I prefer) run the
struts-example and 'take a look under the hood'.

return false

[Tuan H. Le]

Hi,

In my Action class I set an object in one of the session attribute before forwarding 
to a JSP view. But, the  in the JSP view always return false on that 
object.

Below is my code. Do you know what I'm missing? employeeList is an ArrayList object.

If I use a for loop below (see comment code block), then it finds the employeeList and 
return the right data from that array object.

Thanks,
Tuan

 My Action code ***

...
session.setAttribute( USER_EMPLOYEE_LIST_KEY, employeeList );
// Forward to the appropriate View
return ( mapping.findForward( target ) );


* My JSP page *
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

<%@ page import="java.util.ArrayList" %>
<%@ page import="com.phs.ezhr.business.vo.EmployeeVO" %>
<%@ page import="com.phs.ezhr.constant.IConstants" %>

<%
  ArrayList employeeList = (ArrayList)session.getAttribute( 
IConstants.USER_EMPLOYEE_LIST_KEY );

  // *
  // THIS CODE WORK, BUT THE  does not work
  // *
  //for ( int i = 0; i < employeeList.size(); i++ ) {
  //  out.println( "i = " + i + "" );
  // EmployeeVO e = (EmployeeVO)employeeList.get( i );

I mean creating a value object, something like an implementation of 
org.apache.struts.upload.FormFile

to hold the binary data, the content type ("image/png", "image/jpg"  ), 
etc ...

Then, the Action would call the business methods to get this value object and 
would save it in the request, and forward to a servlet that would retrieve 
the value object from the request, set the content type and write the data to 
the response.

This way you can reuse the servlet in case you have documents, like pdfs in 
your database as blobs or something.

Every time you need to stream a file, you only need to define an action that 
calls the business method to get the file value object and save it to the 
request.

In struts-config.xml you would have something like this:






   


and in web.xml

  
fileServlet
the.servlet.that.writes.the.Files
  

  
fileServlet
/fileServlet

I don't know, but my guess is that you meant to use 
someString.equals(someOtherString) rather than someString == 
someOtherString, unless you somehow are using a hidden myString.intern() in 
there.  My guess, in other words, is that you are getting nothing because 
all your "==" tests yield false.  Try sticking a "!" or two in there and 
see if something miraculously appears.  Debuggers are not very clever at 
finding the real problems, like this one, if this is right.

I'm not sure that's the issue, because the session.getAttribute returned a correct 
ArrayList object employeeList and the for loop works fine.

Read the API documentation for the "present" tag.  You'll find it says this
about the "name" attribute:

  Checks for the existence of a JSP bean, in any scope, with the specified name.

That means the key for the object in the table has to have that name.  In your
"logic:present" tag, you've referenced the name "employeeList", but you put it
into the table with a name of "com.xyz.key.USER".

A off hand response, try changing the scope of the object maybe to request

Tiles Idea

[Dan Ritchey]

I recently completed an addon to Struts/Tiles that allows to one determine
at runtime which tiles definition should be displayed based on the incoming
HttpServletRequest and the ServletContext.

I created a Struts PlugIn/RequestProcessor that descends from the Tiles
PlugIn/RequestProcessor and intercepts processForwardConfig calls so that I
can determine what path the request should actually be fowarded to based on
a view selection algorithm.

Below is an example of the XML config file (which is used in conjunction
with the tiles config file).







 




 










Everytime something is fowarded on, the foward path is checked to see if it
is equal dynamic view name, if it is the below algorithm is applied to
determine the path that the foward path maps to for this request.

for each view in dynamic view
 calculate selection score
 (foreach selector in a view's referenced selector set
  if the selector evaluates to true,
  then add 1 to the selection score.

  if the selector evaluates to false,
  then set the selection score to 0 and return.
  end
  return selection score)


 if selection score == 0,
 then continue

 if selection score > previous selection score score,
 then set current view as the selected view

 if selection score == previous selection score,
 then continue.
 end

 if selected view is not set,
 then set to default

When a Selector is evaluated it is passed the HttpServletRequest and
ServletContext.

So far its intended use will be for determing the view based on the user's
current role (like whether they are an admin or a regular user, etc), the
user's preferred language, and site branding and customization to the
clients liking.

I tried doing this with what is already provided with tiles (like using a
controller class for instance), but it didn't seem as powerful or
configurable as I needed it.

So anyway I was just wondering if any of you had any ideas or comments (good
or bad) about this approach, I would love to hear it.

thanks,
Dan Ritchey

Struts -> migrating to JSTL

[flare]

well.. I've read the specs and now I (strongly) want to use JSTL with struts 1.02 ;)
Any recommendation?
I'm going to use struts html + core + fmt jstl. The only problems I can think of is 
how to set 
the same resource bundle of struts in jstl and the i18n stuff (how can I switch locale 
in struts 
and make jstl know about that?) 
Is there a doc that explains how to migrate to JSTL?   

 thanx 

PS does JSTL support dynabeans?

Re: i18n messages in javascript js file

Thanks James,
That's how we had implemented for now, but is it right to have just
javavascript code in a separate jsp and include it in all the other jsp's.
is there any better solution ?

Re: JDK 1.4 and struts

[Melissa L Kelley]

I've started using Struts 1.1 on Linux (Redhat 7.2) using Tomcat 4.1.12
with Sun's JDK 1.4.1. So far, I haven't run into any problems, but I have
only been working on it for a couple of days. And the struts-example.war
deployed like a champ. This is with one of the more recent nightly builds
of Struts. That being said, I'm off to go find some wood. I've got some
knocking to do.

Re: How to add a pre-action

[Howard Miller]

I think I'm seriously missing the point here! I have looked at the example application 
in some detail and it appears to add a parameter (eg, ?action=new) to tell the action 
for a form to perform an initialising action. I don't see it using a "pre-" action.

I am incredibly stuck with the concept of how to code an action that is not 
encumbered with *special* parameters to pre-load the bean data. My particular 
problem is that I have pages where the previous page cannot be predicted, so the jsp 
must have a means of loading its own data.

I would really appreciated some pointers as to how to set this up. *** I particularly 
don't understand how to get the action to call the following JSP *** (ie, I would 
really 
appreciate some specific - example - help on this!! ). At least every method I have 
tried doesn't work.

I do understand how to actually create a bean manually and put in in the scope. I 
don't understand how to set up a generic preload action for a given JSP/ActionForm, 
and what the config should look like.

Again, any help much appreciated.

In fact, the best practice is to always preface a page with an action.  You end
up with actions that prepare information for a page, and actions which process
information for a page.  The actions which process the page information will
always have had the form bean created before you get to the action.  However,
the actions which prepare the page information may have to manually create the
form bean and put it into the appropriate scope.

Note that the welcome page for an application would normally be something like
"index.jsp", which does nothing but forward to an action to start the
application.  You can't preface the welcome page with an action, but you can
make it do nothing but go to an action to prepare the real first page.

Look at the source code for the "example" application for some examples of
using the form bean.  The user guide also talks about the control flow with
respect to form beans.

You want to use the OLD Struts with the NEW JSTL?  (Not that there was an "old"
JSTL.)

You will definitely find it much easier to use the NEW Struts.  In particular,
the nightly build.  That's because, in the nightly build, one of the
contributed libraries is called "Struts-EL".  If you've read the JSTL
specification, you probably can guess what that implies.

That being said, there's no technical reason you couldn't use Struts 1.02 with
the JSTL.  You'd just have to know that the JSTL uses scoped variables, but
Struts will require scriptlet variables in some places.  If you used Struts-EL,
you don't need scriptlet variables.

best praktice: preview of a form

[rainer juenger]

Hi,

I am thinking of a concept how to best realize a WYSIWYIG preview of filed
in form values.

what's the job?
after a struts-from was validated and everything is filled in okay I want to
preview the values in a JSP-Site that shows the just filed in values for
final verification by the User.
If the entered values are okay a further action can be processed (eg.
persistence)
If not the entered values shoud be edited in the input-form.

I tried many ways but all of them do cause certain problems.
What is the most struts conform solution to this problem?

thanks Rainer

You can:

1. In a Action:
	response.setContentType( "the type of the image" );
	OutputStream out = response.getOutputStream();
	... write the data (byte array?) to out 
	return null;

2. Or you could save the bean representing the image (content type, and data)

RE: about images and db

[Frederic Laub]

Hi,

I'm also interested in the two cases.
The first case is clear to me, writing the byte data directly to out.
The second case, I would appreciate if you could clarify. What do you mean
by holding the content type in the bean.
An example of the second option would be wonderful!

Thanks in advance.

Then, the are 2 different requests, the one that returns the html and the

In the html you could have:

And  showImage.do  would be the Action that we talked about before.

A better practice: environment entry vs. initialization parameter?

A few of email addresses needed to be accessed from time to time in my current 
project. They can be definited either as 
initialization parameters or environment entries. I can see some pros and cons of 
those two implementations. Do 
someone have  some experience with those two implementation for a heavy loaded 
application?

How to add a pre-action

[Howard Miller]

Hi,

Can somebody kindly help me with the following...

I want to add a path and an Action class. The action class will then preload data into 
a bean and then forward (do I mean forward) to the jsp that displays the bean. That's 
it. I want this action to be in *addition* to the *normal* jsp/formbean/action setup.

I can't see how to do it in particular

1. I don't think I fully understand how/why an action is associated with a bean in 
struts-config. What does the action servlet do with this information.

2. How do I properly forward from an action to a jsp with the bean information intact. 
It seems to be very similar to an action returning its "input form" to display errors, 
but 
doing this doesn't work.  Whatever I do I seem to get a blank page.

Any help very much appreciated.

Howard Miller
