Re: copyrighted documents in Struts package

If those files are part of Struts package, but copyrighted as netscape's property, is it still legal to use Struts to develop commercial software?

copyrighted documents in Struts package

[Kevin Wang]

Hi,

I found two documents copyrighted by Netscape in struts package.

org\apache\commons\digester\rss\rss-0.91.dtd
and
org\apache\commons\digester\rss\rss-0.9.dtd

I believe I am using struts 1.1... did anyone notice this before?? isn't
struts supposed to be "open source"?

RE: Can I use action path instead of form name in in validation.xml?

[Kevin Wang]

Thanks Robert! Right now my forms are extending ActionForm. Can I just make
them extend DynaValidatorActionForm without changing anything else? What do
I need to change if I do need to?

Yes. You can do this, but you have to use or subclass
DynaValidatorActionForm.
It uses the "path" attribute of the action mapping to determine validation
rules
for the request.

Thanks Vishu,

But my question is that how to put the error messages in the location next
to their input fields. Something like this:


User name: (input box for user name)

First name: (input box for first name)

*Error: Last name can't be empty.
Last name:(input box for last name)


*Error: invalid credit card number.
Credit Card Number (input box for credit card number)

use the "errors" tag under html taglib. When you instantiate an ActionError
and add it to ActionErrors, you can specify a key, which can be linked to
an
entry in ResourceBundle. "errors" tag will pick that up. you can also use
html formatting around the entry in ResourceBundle, so it can go with rest
of your formatting.

Internationalization and file uploads with multipart/for-data

[Kevin Wang]

Hi all,

I am working on internationalization for our web application.By setting <%@
page contentType="text/html; charset=UTF-8"%> and using a filter to set
request's characterset to "UTF-8", I am able to get user's input in Chinese
and send it back to the browser correctly.

However I found that whenever I need to upload a file and add the attribute
"enctype=multipart/form-data" to , I couldn't get user's input
in Chinese correctly. Is it a struts limitation or something I might have
done wrong?

I ran into the same issue, not just with Struts File Upload, but also with
the O'Reilly servlet as well.  Are you uploading from the same box as your

What I found is that if your client is on a different box than the server,
the file upload is speedy.

what will happen if I have Data Types other than java.lang.String in my formbean - say java.util.date?

[Kevin Wang]

I have a formbean which include a field its type is java.util.Date, and I
have two methods to get and set
like these :
Date getMyField() { return dateVar; }
void setMyField(Date date ){ dateVar = date ;}

Now I use  to display this field, it displays the Date with the

You can call request.getParameterMap() which returns a Map object that you

Hi,

Does anyone know how you can add a parameter to the Request object in an
Action?

I can find no interface for it in HTTPServletRequest or ServletRequest.

What I want to do is forward a request in one Action to another Action (by
returning an ActionForward that's configured in struts-config), but add a
new parameter to the request.

Thanks,

RE: POST and GET method

[Kevin Wang]

The 
current ActionServlet passes both doGet() and doPost() to 
process(request, response). if you want your entire application to handle 
doGet() with an error.jsp, ActionServlet is a good place to do so (assuming each 
webapp get its own ActionServlet). If you want to handle them per Action 
basis, you can find out HttpMethod with request.getMethod(), the 
request object is passed to Action.perform() by 
ActionServlet.

RE: Using expressions as attribute values in

[Kevin Wang]

I don't have the latest html dtd but a peek into _form.dtd confirms that you
CAN use expression for the href attribute.


link
org.apache.struts.taglib.form.LinkTag

href
false
true


assuming same is true for _html.dtd, a possible work around is that you
construct the entire url expression first and then assign to the
. something like, 
<%
String url = "http://localhost:8080/internal/"+jsp;
%>

[Kevin Wang]

while  works fine inside pair "s, <%= %> does not. you need to
take away the pair of "s here. in this case, you also need to make sure that
no spaces would appear in the entire query string.

here is my example:

<%
String clazz = obj.getClass().toString();
clazz = clazz.substring(clazz.indexOf(" ")+1); 
String clazzName =
clazz.substring(clazz.lastIndexOf(".")+1);
%> 

 .jsp&objectType=<%=clazz

RE: Dynamic properties

[Kevin Wang]

You 
basically need to add a Hashtable to ActionForm (or its subclass) to hold 
dynamic properties ; PropertyUtils provides set/get methods 
to set/get dynamic properties to the Hashtalbe; and BeanUtils makes usre 
such methods get called before throwing 
a "NoSuchMethodFoundException". I've got it working for simple property with 
12/07/00 nightly built. It should be easy (though time comsuming) 
to do the same for indexed/nested properties.

Double actions observed on "post" to ActionServlet

[Kevin Wang]

I got 
two entries added to the database when submitting one adding request through 
Struts. Got the same on loginAction, ie. logged in twice. However, when I made 
the request via GET (using "/jsp/login.do?user=xx&password=xx" directly), 
only one login action took place. Any explanation?
 
We are 
running Struts 1.0 (12/07/00 built) on Orion 1.4.0.

RE: Dynamic properties

[Kevin Wang]

check out http://archive.covalent.net/jakarta/struts-user/2000/12/0481.xml
for my previous post on handling dynamic properties with Struts.
unfortunately, it is not working with the latest nightly builds as changes
are significant.

indexed/nested properties were not "dynamically" supported.

Automatic/extended properties in Struts

[Kevin Wang]

I've made some changes in three files (attached and virus free :-) to let
Struts handle automatic/extended properties, ie properties that appears on
jsp but not defined by the actionForm bean. 

It is based on 12/16 nightly build. Only simple properties are supported at
this time, as was the original nightly build. Tested on Orion 1.4. Watch
your server's System.out for extended properties... (printed from
ActionForm).

Let me know if you have problem getting them to work.


 ActionForm.java
 BeanUtils.java
 PropertyUtils.java

RE: Article on JavaWorld

[Kevin Wang]

I did something similar in our project to handle "extended properties",
which include "automatic properties" as a special case when not a single
property (and methods) is defined in the ActionForm bean. I tried extend
Struts as much as posible and had to only change BeanUtils in a similar
fashion. Details at
http://archive.covalent.net/jakarta/struts-user/2000/11/0516.xml

You have a point, the article doens't make use of all of Struts feature. I
was simply trying to convey the experience I got during a recent project of
using the Struts JSP tag libraries. This project didn't lend itself to using
the rest of Struts so I had nothing to report there. IMHO the methods
presented do add value to Struts and could perhaps be incorporated. I cant
see anything inherently wrong with changing the Struts code to accomodate
these features.

Hi all,

I just noticed that there is an article talking about Struts on JavaWorld,
at
http://www.javaworld.com/javaworld/jw-12-2000/jw-1201-struts.html, written
by
Thor Kristmundsson, from ATG. This shows, once again, that Struts is more
and
more used and recognized in the Java community.
Unfortunately, the article, IMHO, shows exactly what should NOT be done with
Struts. The MVC pattern is broken (no real form bean, controller code in the
JSP
page, direct forwards to JSP pages, ...), the validation process of Struts
is
bypassed and re-invented, the error management is also re-invented, and this
is
done by modifying the Struts sources, instead of trying to enhancing it by
adding or extending classes.

What do you all think about it?

I personnally think that someone knowing Struts perfectly (Craig, are you
here?), should react to this article and show how all this could be done
using
Struts in a smart way, and explain what the real Struts is able to do.

JB.

How to make ActionForm handle extended properties

[Kevin Wang]

Currently, every form field has to have equivalent field in ActionForm bean,
with both getter and setter method. This requires that a new ActionForm be
generated for each new Struts form (with additional fields).

Our applicaiton requires 'extensibility', ie. HTML/JSP designer should be
able to add new fields to the form without breaking serverside Java code,
including Struts. 

I've made some minor changes to Struts 0.5 to achieve such extensibility.
Basically, it use a Hashtable to save and retrieve extra fields that do not
appear in the ActionForm.

1. Add (Hashtable) properties to BaseActionForm which implements
ValidatingActionForm, with getter and setter methods like,

public String get(String name);

public void set(String name, String value);

  All my ActionForm classes will extend this BaseActionForm.

2. Added a new util class that has two methods that will call the above
methods with the following interface:

public static String getPropertyValue(Object bean, String name)
throws IllegalAccessException, InvocationTargetException,
NoSuchMethodException;

public static void setPropertyValue(Object bean, String name, Object
value)
throws IllegalAccessException, InvocationTargetException,
NoSuchMethodException;

3. Modify org.apache.struts.util.BeanUtils' get/setPropertyValue() to call
my custom get/setPropertyValue() above whenever NoSuchMethodException was
thrown.


This approch worked so far but not very elegant. The need to modify
BeanUtils.java is, of cause, troublesome. Any suggestions?

Thanks.

Does the unmodified Struts example application work for you?  It loads
application resources from a resource bundle named
"org.apache.struts.example.ApplicationResources" -- which ends up being
populated by a properties file
"WEB-INF/classes/org/apache/struts/example/ApplicationResources.properties".

I do not believe there have been any changes in how this is handled since

That's very interesting... when I tried the latest nightly build of struts
w/ Orion 1.4.0, I still get the "Can't find resource MESSAGE" error.  I am
deploying struts-example.war as a webapp, loading it on startup, and having
Orion expand it.  struts-example does in fact have struts.jar in its lib.  I
would think that all I have to do to get the struts-example.war to work is
point to it w/ orion's application.xml and default-web-site.xml, but I keep
getting the "Can't find resource MESSAGE" error.

Is there a trick I'm missing?

Thanks,
Seth

ps I tried the fix for Orion from the INSTALL but that didn't seem to work.

RE: EJBs with STRUTS

[Kevin Wang]

Dave,

I assume that you want me to explain why I favour Orion over Weblogic for
Struts.

Weblogic does not support Struts out-of-the-box though it might in the
future. The main problem is that  can not be resolved in
weblogic.

As for deployment, adding application to Orion is almost effortless. Just
tell Orion where you Servlet 2.2 compliant application is located in its
config/application.xml and it will take care of the rest. In Weblogic,
however, you have to fiddle with additional stuff like WEBLOGICCLASSPATH.

Thanks.

right. we roughly follow j2ee blue print and have clear distinction between
webtier and ejb tier. web tier is one of ejb tier's client and it is
accessing ejb tier through their remote interfaces (jndi/rmi/...). 

>this the main reason for using 2 different products?

the reason for using weblogic is political - it had been chosen
the reason for using of orion is technical - weblogic does not do struts
well

i personally favour orion as it follow j2ee specification much better than
weblogic. it is much less painful to deploy to orion server. there are no
performance comparisons between the two servers available to us.

joe,

i'm not sure whether the server needs to be restarted and that's why i'm not
relying on action.xml to store that changes. a navigator is put in session
that stores infomation about user id, lastURL ... etc and can be updated via
lookup service SessionBean on EJB side where  dynamic configuration is made.

well, Craig just addressed this one. in addition, it is easier to distribute
web tier(s) if needs to.

RE: EJBs with STRUTS

[Kevin Wang]

I'm using Struts with EJB in our project. The application is required to be
configurable at runtime, ie. navigation and jsp content can be altered while
the server(s) are running. 

My current architecture is as follows:

1. EJB tier is served by Weblogic
2. Web tier is hosted by Orion Server, running Struts
3. A lookup service (Session EJB) connects Strtus with EJBs

The lookup service passes various 'business objects'(JavaBeans) betwin the
two tiers. Struts action classes are responsible for populating business
objects with Struts actionForms and vice versa.
