As promised (Struts Presentation)
============================
Craig M.: Can you add the link to the presentation (if you deem it
suitable) to the resources section of the Struts User Guide?
============================
URL forwarding sucks. Given that, I will have to give you the link to
the presentation as it exists on the server space I am borrowing until I
get my own server box. The URL may change in the future to my
computer-programmer.org domain.
The Struts presentation I did can be found (at least for the time being)
at:
http://www.us-eh.com/craiger/articles/struts/
Let me know of any problems or suggestions you may have about the
presentation!
Thanks,
Craig.

Sorry for the no response on STRUTS-DEV ... I've been heads down on bug
fixes
getting ready for a 1.0 release.
The primary issue for Struts is to be compatible with as wide a range of
XML
parsers as possible, because different apps will have different
preferences. To
date, there are a few SAX2 parsers, but only one compliant one that
conforms to
the JAXP APIs (see next paragraph), which is also matters.

The javax.xml.parsers family of interfaces are part of the Java API for
XML
Processing (JAXP) suite, which ensures applications that they can be
independent
of the actual parser being used. Using
org.apache.xerces.parser.SAXParser
directly would require a Struts app to use only Xerces, which is not
optimal for
every environment.
In addition, the Apache-specific APIs have been in substantial churn
over the
last few versions -- my preference will be to let this settle down (and
let
Xerces catch up to implementing the standard JAXP 1.1 interfaces) before
updating the technology that Digester uses.

Deprecated API
Posted by Alan Yackel <ay...@home.com>.
I tried asking this on struts-dev, but got no reply. What I'm wondering is
why
is the Digester built on the deprecated HandlerBase instead of the SAX2
DefaultHandler? Switching over to the newer SAX2 classes doesn't required
too much
work. I did it with one other application. It's mostly changing
AttributeList to
Attributes and changing the parameter list on a few methods.
Also I'm curious why Struts doesn't use the
org.apache.xerces.parser.SAXParser instead
of the one in javax.xml.parsers. I would think that apache projects would
try leverage
work from other apache projects. I'm in the middle of building a software
application
based on Struts for an internet consulting company. I love the features and
flexibility
of Struts, but it's nice to keep current with technology.
Just asking,

That is correct. The property utility modules will work on any JavaBean, but

Re: As promised (Struts Presentation)

Maya,
1) The language should change from the default after the user changes his/her browser
language if:
1. the user does a refresh in his browser (or perhaps just clicks a link to another
part of the app)
2. the language they have choosen is supported by the web app
When you specify the Resource file in the application init param it simply specifies
a default Resources class. After that, if the locale changes it tries to append the
ISO language characters to the end of the class name to see if it can find a
supporting Resource file.
2) Not sure I understand the second question :(

Recently I fix <html:img> tag and post it to the struts-dev. If Craig

One approach would be a runtime expression:
<bean:header id="referer" name="Referer"/>
<html:link href="<%= referer %>" .../>
which works because the <bean:header> tag creates a scripting variable along with a page
context attribute, in the same way that <jsp:useBean> does.
Otherwise, we would need to enhance the link tag to accept its href from a bean (which is
not a bad idea), and/or you could write a custom tag of your own.

JVM load all files in properties bundle at once and all this
resources can be used in run time. Example of switching to another
locale -
public class ChangeLanguageAction extends Action {
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
String country = ((ChangeLanguageForm) form).getCountry();
String language = ((ChangeLanguageForm) form).getLanguage();
String source = ((ChangeLanguageForm) form).getSource();
HttpSession session = request.getSession();
ActionForward forward = null;
setLocale( request, new Locale( language, country ) );
if( source==null )
forward = (mapping.findForward("success"));
else {
forward = new RedirectingActionForward();
forward.setPath( source );
}
return forward;
}
}
MM> 2/ How replace images with a text through properties file? (I think this question

You can store image file names in properties in use it in <img> tags
- <img src='<bean:message key="picture.cat.english"/>'>
<img src='<bean:message key="picture.cat.french"/>'>
May be I not understand your 2/ question... Explane please, if so.

The same error is on pages 29 - 31.
After reading your document, I have two questions:
1/ Is it possible to change a language on-line. For example one user uses English
language with his browser, then he switchs to French. Can Struts handle this? I
think, in your document the properties file is loaded in the beginning
ActionServlet startup.

Kewl!
I think I know what I'll be doning after Dark Angel tonight!
I did notice one point on page 17, where it says "Struts will only
handle models in an automatic fashion if you extended
org.apache.struts.action.ActionForm"
Is the word "only" accurate?
I believe Struts works best if the form beans are ActionForm subclasses,
but I think the form and action would work just fine with any JavaBean.
