Re: [OT] Anyone else mess around with Wicket?

[Nick Heudecker]

I figure I'm obligated to respond, since my comments were cited in the
original email. :)

I have to disagree with complaints about Wicket's complexity, but only
because I've been using it to build a product for the last few months.
Without heavy usage, I don't think I'd have the same positive opinion.  Some
things, like displaying conditional content, seemed cumbersome initially,
but now I appreciate having the logic in one place, rather than split
between the Action and the JSP.

Lack of markup in the templates and the concept of a page map have really
simplified my development and made features much easier to add, especially
when compared to Struts.  Not having to update struts-config.xml and
validation.xml is also quite nice.

I won't use JSF.  Tapestry is okay, but still requires some form of
configuration either through XML or annotations.  Additionally, there's
still some logic in the markup.  I don't have to do that with Wicket.

All that said, I'd prefer if you don't use Wicket.  I'd like to keep this
competitive advantage to myself. :)

Re: more on wicket

[Nick Heudecker]

The rawInput variable is set in the FormComponent when the validation
starts.  If validation succeeds, rawInput is set to an internal constant and
processing continues.  If validation fails, the rawInput for each
FormComponent is still available and is rendered on the input page.

As far as adding an IntegerValidator to a TextField, it's pretty simple:

TextField age = new TextField("age");
age.add(IntegerValidator.range(0, 130));
add(age);

The last call adds the TextField to the Form object.


Nick, Wicket does look interesting, but I'm curious, how does Wicket

There is configuration, but it's minor and contained in the Application
class.  Still no XML.  If you really want to use XML to configure the
Application, the recent Spring integration allows you to do that.

Regarding the problem domain issue of Wicket, I've done a lot with it so far
and haven't had any problems solving real issues with it, with much less
hair-pulling than Struts.  I've built a number of Struts applications and
consider myself an expert with it, but it's unlikely I'd build another
application with Struts while Wicket is available.

Re: more on wicket

[Nick Heudecker]

You can create aliases in the current version to provide shorthand names for
pages.  Wicket 1.2 will allow you to mount pages at specified URLs, which
should get around this problem.

Re: DispatchAction parameter getting dropped by IE

[Nick Heudecker]

Now I'm thinking this has something to do with the charset not getting
set in IE.  Users are copying and pasting content from Word into
textareas and getting this error.

Is it possible Tomcat can't parse the incoming form data and nothing
gets passed to the Action?

DispatchAction parameter getting dropped by IE

[Nick Heudecker]

Occasionally, one my my users will receive the following error message:

"javax.servlet.ServletException: Request[/foo] does not contain handler
parameter named 'p'.  This may be caused by whitespace in the label text."

There isn't any whitespace in the label text, and this only occurs
with IE.  It's like none of the form properties are submitted.  Has
anyone else experienced this and discovered a solution?

Re: Hibernate data at startup

[Nick Heudecker]

You have a few options. To initialize Spring, you can either use the Struts
plugin or the web app context listener. Once that's done you can either use
a startup servlet or a Struts plugin to load the data and put it into the
servlet context. That way it only needs to be loaded once and is shared
throughout the application.

It's pretty simple, but not very obvious.

Re: Struts and Hibernate lazy

[Nick Heudecker]

The most common way to solve this problem is to use the Open Session
In View pattern, which leaves the Hibernate session open until the JSP
has finished rendering.  Typically accomplished with a filter, there
is also a Struts plugin to help with this pattern.

Google for "Open Session In View" and you'll find a handful of solutions.

While backwards compatibility is nice, I would rather see a better

compatibility should be required between point releases, but all bets
are off for major revisions.

Since we're offering suggestions, I would like to see a simplified

Re: Dispatch Action "Whitespace In Label Text" and Missing Parameters

After some additional research, IE is failing to submit HTTP

Re: PDF Streamed To Client

[Nick Heudecker]

Brian:

This is pretty simple.  Just get the output stream from the response
object and stream the file down.  Return null from the Action's
execute method:

private void returnFile(File f, OutputStream out) throws IOException {
FileInputStream fis = null;
try {
fis = new FileInputStream(f);
byte[] buf = new byte[8 * 1024];
int bytesRead;
while ((bytesRead = fis.read(buf)) != -1) {
out.write(buf, 0, bytesRead);
}
} catch (IOException ioe) {
log.error(ioe, ioe);
} finally {
if (fis != null)
fis.close();
}
}

Dispatch Action "Whitespace In Label Text" and Missing Parameters

[Nick Heudecker]

I've run into a strange problem with DispatchAction occasionally
failing to find the parameter used to lookup the method to process the
request.  I get the following familiar error:

"Request[myAction] does not contain handler parameter named 'method'. 
This may be caused by whitespace in the label text."

This error may occur one time out of five for the exact same workflow
and values, so the action doesn't fail every time.  Here's more
information about the error:

-) Seems to be IE-specific.  Testing with Firefox doesn't cause the error.
-) There is no Javascript submitting the form.  
-) There is only one form on the page.
-) The user clicks the submit button to submit the form, instead of
pressing enter.
-) All of the HTTP parameters are gone, which explains why the
'method' parameter is missing.
-) There are a handful of filters in the web application.  Since the
error doesn't occur each time, I don't think the filters cause the
error.

I've exhausted my other resources to find the cause of this problem.
I'm stumped.  Does anybody have suggestions?

Re: Off Topic Post Air Time vs. Struts Answers

[Nick Heudecker]

Terry:

I agree with you that struts-user is mostly noise, although you
phrased it much better than I did.  I know it's frustrating to have
your question go unanswered, but I really don't think it's
intentional.  There is so much cruft on this list, with the same
questions asked repeatedly, that your question probably just fell
through the cracks.

The vast majority of the questions here should be posted on the JDC
forums.  If people would do that, and make even the most basic attempt
to check the archives and/or Google, the number of off-topic posts
would fall.

I guess I'll wait to see how many angry responses I get. :)

Re: site "shutdown" best practice?

[Nick Heudecker]

You could set a property in the context scope that flags the
'maintenance page' or something.  To detect the flag, you could use a
filter to redirect the user to the maintenance page, or have your base
Action class look for the flag and react accordingly.

Ideally, you'd do this from some form of admin page.

Re: html:cancel usage

[Nick Heudecker]

I believe the validation still happens because the validation step
occurs before the appropriate method in the action class in
determined.  I got around this by turning off automatic validation.

[ANNOUNCE] XDoclet Struts DynaForm 1.2.2 SNAPSHOT

[Nick Heudecker]

This release adds validation support to the DynaForms generated by XDoclet. 
Using the "@struts.validator" tags, you can create the validation.xml for 
dynamic action forms in the same manner used by the struts.form XDoclet feature.

Please note that this is a SNAPSHOT release, created from a fairly recent 
XDoclet CVS snapshot.  (I'm not an XDoclet committer, and sf.net has been having 
problems with anonymous CVS lately.)  I would like additional people to test 
this version.  It works fine for me, but YMMV.  If I can get a few people to 
confirm that it works for them, I'll submit it as a patch to the forthcoming 
XDoclet 1.2.2 release.

In addition to the validation support, this patch also supports Struts 1.2.1 and 
1.1.3 version of the validator.

If I got anything wrong or missed anything, please let me know.

Re: Réf. : Re: ActionForm vs Hibernate POJO

[Nick Heudecker]

If you're using XDoclet, I wrote an extension to allow you to define 
DynaValidatorActionForms using XDoclet tags.  You can download it from here:

http://www.systemmobile.com/code/xdoclet-apache-module-sm-1_2.zip
Using this extension, you may define your Hibernate mappings and 
dynaform definition in your POJO.

Re: release of struts-faces library

I want to use the struts-faces library, but the existing articles and

 I haven't yet had time to dig through the source to answer this for 
myself.

Re: [OT] RTF & PDF export options

Brian:
I'm guessing that you can do this with iText.  It has RTF and PDF 
writers, and I think you can use the RTF as the source doc for the 
output PDF.

FYI, if you're running iText on a headless server, you'll need to set 
java.awt.headless=true.  This works for JDK 1.4.x.

Re: MessageResources Question

[Nick Heudecker]

Hi Ken:
A JDBCMessageResources class already exists.  I believe that James 
Mitchell wrote it.  After a quick search, I couldn't find any additional 
links to it, however.

Ken Pullin wrote:
I've been looking into extending the MessageResources class and providing my own 
MessageResourcesFactory.  The end goal is to house the ApplicationResource files in a 
database table.  The issue I'm noticing is that the MessageResources class maintains a 
HashMap of key/values called 'formats'.  So any class that extends MessageResources 
only get's called when the particular value is not in the cache(hashmap) in the 
MessageResource class.  This is the method that gets called in the MessageResources 
class:
String formatKey = messageKey(locale, key);
 synchronized (formats) {
 format = (MessageFormat) formats.get(formatKey);
 if (format == null) {
  String formatString = getMessage(locale, key);
  if (formatString == null) {
  if (returnNull)
   return (null);
  else
   return ("???" + formatKey + "???");
  }
  format = new MessageFormat(escape(formatString));
  formats.put(formatKey, format);
 }
 }
Notice how the 1st step is to check to see if the formats hashmap contains the key.  
If it doesn't it then calls the getMessage(locale,key) which is provided by my 
implemenation class.  At that point, it gets back a value and then puts it on the 
HashMap.
The problem I'm having is when I want to update a value.  How do you tell the 
MessageResources class to refresh it's cache.  This becomes even more complicated if 
the application resides in a clustered environment.  You could use OJB or even Entity 
Bean to retrieve the data from the database in the Custom Implemenation, but you still 
have the problem with the MessageResources class maintaining a seperate cache.  The 
EJB or OJB classes would contain the correct values, but the cache at the parent level 
would not.  I basically need a way when a value gets updated to tell the 
MessageResources class to either 1) clear it's cache all together or 2) take the value 
off of the HashMap so the next call to it would go to my custom implementation.
I hope this wasn't 2 confusing
Thanks

Re: [OT] A first look at Spring vs Struts

I've seen 'rogue' developers do remarkably stupid things with Struts and

Well you can do almost anything in there since you're in a servlet, so 
you can totally break Struts concepts. You can do redirects (when you 
shouldn't) you could not use a Form bean to capture properties, you can 
do business logic in there when you shouldn't. You can make new 
instances of ActionForms and put them in Session scope - point is you 
can do anything you want, so if you have some developers on your team 
that aren't following best practices, they could potentially make parts 
of the application in some renegade fashion. Sometimes you do need to do 
some custom things in Struts, and this is where I think Struts falls a 
little short compared to frameworks like Spring since it is less flexible.

Re: How to display error msgs in a pop up window

[Nick Heudecker]

Another way would be to use some JavaScript on the input page that opens 
a new window, the popup, and writes the error messages directly to that 
using the document.write(...) function.  Pretty easy really.

Frank Zammetti wrote:
One way to do this (the only way I can actually think of) is this... 
write your logon page as you would normally in Struts, i.e., pretend 
your going to display your error message there.  That means 
re-displaying the user's entries, all that.  But, instead of displaying 
the messages, open a new window via JavaScript as a result of the pages' 
onLoad event, and load into that the error messages (either via 
scripting or calling an Action, which means you would have had to 
persisted the messages somehow on the server and referenced them, i.e., 
maybe set them in session during the failed logon Action call and 
retrieve them for display).

As far as I know, there is no way to send a redirect to the browser 
telling it to open the target in a new window from the server, so any 
response the server sends has to technically go to the same window that 
started the request (unless of course you targeted a new window to begin 
with, but it doesn't sound like you can do that).  So, your left with 
"faking it", that is, you will in fact re-draw the page, but it will 
look like a new window is opening with the error messages.  If the 
appearance is all you want, this should do, but if there's some reason 
you can't overwrite your logon page (like maybe some stored data in 
script elements that can't be overwritten?) then I think your out of luck.

Re: generate struts ActionForm & strut's jsp from hibernate's map ping

[Nick Heudecker]

Some people use the @struts.form XDoclet tags to create their form classes,
although I wasn't able to get it to work with non-EJB classes.  I've written
an XDoclet extension to create dynamic form bean definitions to get around
this.

Your problem is that you're going from HBM > Java Bean > Form Bean, while
XDoclet is Java Bean > (HBM, DynaForm Bean Definition).  You could hit the
HBM files with some XSL to create your form beans, however.  Shouldn't be too
hard and others may find it useful.
