Re: [Fwd: Re: [fileUpload] Question about file name]

[Dakota Jack]

Frank,

If the File class does not normalize the string used to create the
File, then there is a bug.  There seems to be a bug in one version of
Linux and that has been reported to Sun.  The constructor for File is
as follows:


public File(String pathname) {
if (pathname == null) {
throw new NullPointerException();
}
this.path = fs.normalize(pathname);
this.prefixLength = fs.prefixLength(this.path);
}

Notice that an object fs is called to normalize the pathname.  The
object fs is created as a static field in all File classes as follows:


static private FileSystem fs = FileSystem.getFileSystem();

The FileSystem class is an abstract class that has to be implemented,
of course, for the os on which it exists.  So, the basis for the class
is a JNI method:

public static native FileSystem getFileSystem();

Sun did not go to all this trouble without expecting the actual
separators to be normalized to whatever system a file is created on,
so that no matter what your path happens to be in creating a File
object, file.getName() should return the name without a file
separator.  Is this helpful?

The intent wasn't that you run AbstractJsfTestCase itself as a test
case -- as it's name implies, it is an *abstract* base class.  The
convenience it brings is automatically setting up the mock environment
suitable for testing something like a ViewController implementation.

The suite() method is primarily a reminder that you need to
reimplement the method in your concrete classes.

I don't always use an IDE -- it's nice to have the visual clue.

According to the TestCase JavaDocs, you're still supposed to call
setName() if you use the TestCase no-args constructor.  It's easier to
avoid mistakes by letting the compiler catch the fact that you didn't
implement a constructor.

I found the page, which discusses the same approach:
http://fy.chalmers.se/~appro/hcntl/

"What if ACTION handler [on the server] doesn't sent the result
immediately [to a browser], but spools it on server and then convinces
the browser to fetch it (preferably with GET method) at some other
location? Then browser presumably wouldn't get the crazy idea about
caching the form data. Moreover if all results are fetched at the very
same URL, then browser should feel motivated to "accumulate" them in
the same history slot."

I came up with exactly the same idea before I saw this one, then I
searched the internet. Which means that it is not that easy to invent
something really new.

See "Web Controls in Struts and DialogAction" thread, where I
collected some info about web controls and about controlling the
history.

Hi Wendy,

Thank you very much for your reply.

Yes, I also thought that I could test the key, then check to see if the
value was empty. But just how to do it is eluding me. I think part of
the problem might be this:

USAGE NOTE - If you use another tag to create the body content (e.g.
bean:write), that tag must return a non-empty String. An empty String
equates to an empty body or a null String, and a new scripting variable
cannot be defined as null. Your bean must return a non-empty String, or
the define tag must be wrapped within a logic tag to test for an empty
or null value.

(from the Struts User Guide for bean:define at
http://struts.apache.org/userGuide/struts-bean.html#define).

I'm trying to do something like









	 


But it's failing (I think) because the bean:message returns an empty
String. I would wrap it in a logic tag as suggested, but if I could do
that, I'd just use the same logic for my logic:notEmpty tag instead. So
finding a way to take that value and assign that to a variable which I
can then test to see whether or not it's empty is what I'm trying to do.

It was not my idea to add all of these empty i18n values: the i18n team
did it. If I can't find a way to make this idea work, that's my
alternate path. If that's the road I need to take, I can do it -- I was
just hopeful I could do this a little more elegantly.

Thanks for your input. Any further ideas?

Quick synopsis: I have localized i18n messages defined in my tiles

processing. I can test that the key is non-empty, but I haven't yet

If you can test the key, then it would seem that removing the empty
messages would solve the problem.  Why are the empty ones there in the
first place?
Can you get rid of them?

Re: Multiple user - problem

[croffman]

I remember I have faced the similar problem before with only just servlets. 
Previous problem was, had a servlet containing a class level variable which 
holded the data. When multiple users hit the servlet, then the response data 
was switched to the users.

Here, in the action class, there is an inner class, which has a object (obj) 
that contains all the data. I am thinking this may be causing the problem. This 
looks like similar to the problem mentioned above and as Dave mentioned 
(>Do you keep any non-synchronized user-specific info in an instance of a 
class that is only instantiated once (like a servlet or action)? That gets a 
lot of people even though it's in all the documentation).

Any suggestions/inputs on this?

Thanks.

Well, if I'm hitting a form with existing values (like an 'edit'

that doesn't strike me as an appropriate place to fill a bean with 
values from a DB. Other than occasional checkbox games I've never

Re: program for drawing buttons

[Frank W. Zammetti]

Not sure if you are looking for canned buttons or your own custom jobs,
but if you are OK with a Windows program, I highly recommend Xara
WebStyle.  Even though it uses templates, and thus you are somewhat
limited in what you can do, there are a TON of templates, and you can
modify them a fair amount.  And best of all, it takes most of the manual
work out of your hands... very nice to use if you are making lots of
buttons and tabs, as I had to do, with text that might change every now
and again.  Wouldn't want to do it by hand!

Good point.

OK, so thinking simplistically..

final char PATH_SEP = File.pathSeparatorChar;
final char ANTI_PATH_SEP = File.pathSeparatorChar == '/' ? '\\' : '/';
String test = "/sub/dev/test.txt";
int lastSep;
lastSep = test.lastIndexOf(PATH_SEP);

Thanks for the quick responses.

Here is some more info:

1. >Is it worse with more users?
This was done by manual users, before load testing. Couldn't try that now.

2. >Do you keep any non-synchronized user-specific info in an instance 
of a class that is only instantiated once (like a servlet or action)? That 
gets a lot of people even though it's in all the documentation.
Looks like there is a similarity. But not sure. Had a MAIN action class 
(which extends from TilesAction), which contains a protected class defined 
and that got the CDTO in it. Whereever needed in all the action classes, the 
CDTO is got from this protected class. Is there any problem here?


3. >-synchronisation of all method calls
No where explicit synchronization is being used in the application.

4. >-scoping of data entities(assuming you are implementing with beans)
Kept the forms in request scope.

5. Also - are you resetting all of the properties in your forms classes. 
If not, some of the data set by one user can bleed over to another user.

As using DynaValidatorForm, not sure how to reset the properties.

In the app, are using Struts form-beans 
(org.apache.struts.validator.DynaValidatorForm). And in the action classes, 
calling the delegate by passing the cdto (custom data transfer object), 
which contains the request data. And when the delegate calls the EJB's, it 
gets the data from database and populates the custom data transfer object 
and sent back to the action class. And in the action class, this cdto is 
copied back to form.


The wrong data came up for one user only. Is there any chance that this cdto 
is shared and being used for two users. Couldn't think of a chance, but...? 
Is there any chance by POINT #2 above.


And EJB's are stateless and Entity Beans are with container managed 
persitance.


Once again thanks for your suggestions.

both concepts are applicable in that
scoping of session based information should ultimately pull from
user-neutral entity (such as Class Object) whose end of life is not
dependent on either client session passivation or client session

Any underlying synchronisation mechanisms for entities (synchronised
objects) are entirely dependent on selection of scope and
whether the implementor is controlling the object via declarative or

RE: Multiple user - problem

[Ray Madigan]

The class org.apache.struts.action.ActionForm has a reset method.  For a
long time I would add form property variables without handling them in the
reset method.  I would get old values in the form and was getting spurious
data in the forms.

It is hard for me to believe you got past a single user with out resetting
the properties, unless you only write to them.  If you use the form
properties to assist in populating your form, the properties need to be
reset.

Web Controls in Struts and DialogAction

[Michael Jouravlev]

On 6/9/05, Adam Hardy <[EMAIL PROTECTED]> wrote:
> your further discussion lost me since I only have a vague concept of
> what the terms web control and portlet actually mean.

I guess we actually need to establish some difinitions. I searched
Struts list but did not find relevant info. If it is there, I would
appreciate the link.

Microsoft uses term "web control" or "server control" or just a
"control" a lot, so I searched on ASP.NET websites for the definition.
Microsoft defines web controls as "components that run on the server
and encapsulate user-interface and other related functionality."
Pretty generic.

Digging further: "The page and the server controls it contains are
responsible for executing the request and rendering HTML back to the
client. Although the communication between the client and the server
is stateless and disconnected, the client experience must appear to be
that of a continuously executing process. This illusion of continuity
is created by the ASP.NET page framework and by the page and its
controls." Ok, not they talk about state.

A control may have all or some of these characteristics:
* View state
* Properties
* Ability to render itself
* Life cycle (see below)
* Events
* Styles
* Design-time functionality
* Localization, licensing, and deployment

ASP.NET lifecycle of a control: 
* Initialize
* Load view state
* Process postback data
* Load
* Send postback change notifications
* Handle postback events
* Prerender
* Save state
* Render
* Dispose
* Unload

For comparison, JSF lifecycle:
http://www-128.ibm.com/developerworks/java/library/j-jsf3/
* Retrieve component tree
* Store submiteed values
* Validate values
* Bind values to backing properties
* Handle events, invoke methods
* Handle navigation
* Render components

So, based on above information, I would say:

* A web control is a server-side component.
* Web control is a stateful object. Microsoft calls this state a "view state".
* Control can render itself according to its current state.
* Control can process input data and events.

Based on portlet spec and on my usage of  directive, I
will also add:

* A control must render itself in response to GET request. Thus,
anytime a user refreshes a parent page, the control whould render a
proper content. This is a simple alternative to portlet's doView()
* A control must use only _one_ URL for GET requests, so that parent
page did not have to modify the URL every time. That means, that
control can be just "dropped" on a page using one single URL, and then
it would render a proper content depending on state.

Based on my hatred to POSTDATA messages, I will add:

* A control should not frighten a user with POSTDATA messages.
* A control should take efforts to prevent double submits.

So, in my understanding, a control is a UI-enabled isolated object,
which runs on server. As long as it provides a URL to render it, and
accepts input data and events (button clicks), we can call it a
control

I did not say much in this email, did I? ;-))

Implementation details.
---
By default, .NET webapps store state on the client, passing it back
and forth in _viewstate hidden field. I guess, the reason for this is
to save session memory. I am totally against this kind of state
handling for number of reasons, which I got tired to repeat. I prefer
to store state on the server. DialogAction stores viewstate in the
session-scoped form bean. By doing this, it achieves a "clean" GET
request, not polluted by parameters. This allows to use the same GET
request for different result pages, thus preventing browser page
history from growing.

Also, because DialogAction uses redirection, there are no postbacks.
All input events occur as a completely separate distinct POST request.
There is a logical postback, though, which is every POST request after
control has been initialized. The price: DialogAction has to be
explicitly initialized.

It is not just mapping, it is the request that is sent to server. I
must reread HTTP specs, but it seems to me that POST request cannot be
thrown out by browser, unless it is succeeded by redirect. Maybe I am
wrong on this... Anyway, usually you would not have two identical POST
requests, since the input data is different. And the data counts, too,
not just base URL.

You can do that without using DialogAction, and you will build another
DialogAction yourself ;-)

Re: Is there anyway to access this forum online?

[Max Cooper]

I'm on several high-traffic lists. Here's my recommendation:

- though people often try this as a way to reduce the clutter, don't use
digests (delivery option where you get a bunch of posts crammed together
into one email message), since they are hard to read and even harder to
reply to -- digests are really intended to be broken up into individual
messages again on the client side (before you see them in your inbox),
but people started reading them directly at some point, which was a
terrible mistake

- Do this, it's great! -- setup a folder for each mailing list you
subscribe to and create a filter to deliver messages from the lists into
those folders automatically (all decent mail clients can do this, and
procmail or maildrop can do it on the server, which is even better if
you use multiple computers to read your mail)

That way you can just ignore the list (without cluttering your inbox)
until you have time to read it.

RE: Test whether an application resource is empty

[Chris Loschen]

Well, that's certainly something I can consider for the future. For
right now, our product is already pretty huge, and I think I would get
shot if I tried to add another set of jars to the classpath, even if in
the long run we'd be better off.

The best solution I've been able to come up with is to punt: insert
another tile to all of these screens, which is blank if there is no
content and a small JSP page if there is content. If there is content,
write it out with the usual  tag. 

Does anyone have a better solution? This will be a pain, but I think it
will work.

Chris,

Struts contains an EL package for its tag libraries. Yes, you can use
EL!

But it doesn't matter if you're using Struts or not. If you're using a
Servlet 2.3 container, you can use JSTL which you want to use. If
possible avoid the  and  tags, and use JSTL instead. These
are built with EL.

I'm trying that, but I'm getting the same results as I did when I used

Subject: Test whether an application resource is empty

Hi all,

I'm using struts 1.1.

I have localized application resources keys defined in my tiles
definition file. In my JSP, I use the tiles attribute and then display
the localized message using the key.

However, in some cases, the localized value is empty: there is no value
for that particular locale or that particular instance. In those cases,
I want to avoid writing out the key at all, but I'm having trouble
figuring out how to make that test.

Specifically, I have tiles defs like this:



Etc.


And the localized values are something like

tiles.main.admin.manageHierarchy.businessStruc.add.directionToUser=

(so no value for that key).  

In my JSP, I've tried several ways to test whether the key value is null
or the length is 0, but none of them have worked yet. For example:

 <% if(directionToUser !=
null && directionToUser.length()>0){ %>

<%
}%>

Problem here is that directionToUser is the key, not the value, so it's
never null, and I get the empty div tags I'm trying to avoid. So I tried
variations like this:











That one returned "Define tag can contain only one of name attribute,
value attribute, or body content". I've tried lots of variations similar
to that, but haven't struck upon the right one yet. This SEEMS like
something which should be pretty simple, but I'm missing something. Any
suggestions? Thanks!

Do you keep any non-synchronized user-specific info in an instance of a
class that is only instantiated once (like a servlet or action)? That
gets a lot of people even though it's in all the documentation.

Without any more specific information it'll be really tough to be

Re: [ANNOUNCEMENT] Struts Dialogs: DispatchAction on steroids

[Adam Hardy]

OK fine on the robustness front - I off-handedly said robustness because 
I normally equate less code with robuster code. But don't let's bother 
discussing that.


So what you are saying is that really all you need to do to implement 
this feature is to keep the struts mapping the same and put no-cache 
instructions in the page header.


I can do that anyway without using DialogAction, right? Unfortunately 
your further discussion lost me since I only have a vague concept of 
what the terms web control and portlet actually mean.

And, you cannot create what I call a "web control" without redirection

you creating a control out of it, as of very simplified portlet. But
portlets has a specific API, like doDispatch() or doView().
DialogAction does not have API, simple reload works as doView(). It is
a actually a big thing, and ability to create a web control allows to
have a simple portal without portlet container. You just drop an URL
to master page, and you do not care about anything else. Whenever
master page is reloaded, the control is reloaded too, and it displays
content, reflecting current control state.

About simplicity. Funny that you mentioned this, because creating a
dialog using DialogAction is simple, just use your form bean fields,
or use a nested business object within a form bean with session scope,
and you get event model, storage for your dialog data, and message
handling.

It might be not a big deal for you, if you do not play with browser
buttons like a kid. If you do not feel like clicking Refresh just
because of fun of it, or clicking Back just to check what happened to
previous page, if you are not annoyed by POSTDATA messages, then you
might not appreciate what DialogAction does. But for me POSTDATA
dialogs are infuriating, I simply hate them.

And, if the above did not convince you: Ruby On Rails adopted the same
two-phase approach to I/O forms. JSF provides the same features, if
you look at JSF samples, all backing beans are defined with session
scope, you just need to put  tag in config file. Spring MVC
has similar features with RedirectView class.

The DialogAction may not be perfect (yet), and may need some
improvements, but it works and it is pretty stable. I will be glad
hearing about possible updates and changes.

This is all you need


 


You can store your Collections in either the 
application/session/request/page scope. Be careful which one you store it 
in and what names you use as the key as the bean will check them all!!

property is the name you give to the select.
collection is any type of collection I use ArrayLists.
The objects in your collection must have a getValue method and a getLabel 
method.

The name value is optional. Only use it if you want to dynamically set the 
option in focus. The object who's key is "TESTSELECTOBJECT" in either the 
application/session/request/page scope must have a getTestselect method. 
If the value returned by getTestselect method matches a value in one of 
the options that option will be in focus.

Dave.

Hi All!

I've never used this tag before and I'm not so good with taglibs then 
please correct my mistakes if I commit any.

I got the following example in a recent thread here in this mailing list:


 



Ok, few things I could already understand, in the html:select tag there 
are 2 properties(in this case I know) name and property; name is the form 
name and property is a specic attribute in this form bean that is related 
to this field;

In the html:options we have name that is the form bean name, property is 
my collection, labelName is a field of my bean into the collection, and 
labelProperty is the final html option's value and also a field of my 
bean, right?;

does name in both tags can be directly found in any scope? I mean if my 
form is either in request or session, is it going to be taken? or am I 
missing something?

Property in the html:options tag can be any kind of Collection? can it be

[Shale] AbstractJsfTestCase - Eclipse

[Carlos Fernandez]

AbstractJsfTestCase, implements a public Test suite() method.  Eclipse
checks for this method when you tell it to run a class as a unit test.  If
this method it exists it will use the returned Test class to determine what
tests to run.  Since the Test returned only includes AbstractJsfTestCase -
Eclipse chokes and throws: 

junit.framework.AssertionFailedError: No tests found in
org.apache.shale.test.base.AbstractJsfTestCase

Granted, I can just subclass suite() in my concrete test cases . . . but I
am lazy and would rather not do this.  Just wondering why the base test
class implements this method, since most IDEs and ant can work just fine
without it.

Also, why does this class not include a no-arg constructor?  Again, I am
just lazy ;)

BTW - the shale test classes make JSF much easier to test!  That might be an
understatement.

RE: Test whether an application resource is empty

[Benedict, Paul C]

Chris,

Struts contains an EL package for its tag libraries. Yes, you can use EL!

But it doesn't matter if you're using Struts or not. If you're using a
Servlet 2.3 container, you can use JSTL which you want to use. If possible
avoid the  and  tags, and use JSTL instead. These are built
with EL.

Hi all,

I'm using struts 1.1.

I have localized application resources keys defined in my tiles
definition file. In my JSP, I use the tiles attribute and then display
the localized message using the key.

However, in some cases, the localized value is empty: there is no value
for that particular locale or that particular instance. In those cases,
I want to avoid writing out the key at all, but I'm having trouble
figuring out how to make that test.

Specifically, I have tiles defs like this:

(so no value for that key).  

In my JSP, I've tried several ways to test whether the key value is null
or the length is 0, but none of them have worked yet. For example:

 <% if(directionToUser !=
null && directionToUser.length()>0){ %>

<%
}%>

Problem here is that directionToUser is the key, not the value, so it's
never null, and I get the empty div tags I'm trying to avoid. So I tried
variations like this:

I guess I am doing bad advertising for my product. (With the voice of
car salesman) let's go over figures once again.

The point is, that a dialog written with DialogAction will never work
worse, than standard cached page. In the worst case scenario, when
browser does not honor cache headers, and does add everything to page
history, you will get the same behavior as a standard application.
That is, when you click Back, you will see a stale page, cached by
browser. And if you entered invalid value several times, then you
might need to click Back as many times as you entered invalid value,
to return from this dialog.

But! This behavior is _no worse than standard caching, non-redirecting
application_. DialogAction does not make your code or UI less robust.
Also, according to statistics, Opera which is the mental case here, is
used only by 2% of users.

On the other hand, if you use any version of Netscape starting from
4.x, (yes, Netscape 4 works great), Mozilla/Firefox or Internet
Explorer (I could not find IE4 for testing), then your users get
immediate benefits in user experience and in overall application feel.
And, you cannot create what I call a "web control" without redirection
and two-phase I/O processing. Think of DialogAction, especially when
you creating a control out of it, as of very simplified portlet. But
portlets has a specific API, like doDispatch() or doView().
DialogAction does not have API, simple reload works as doView(). It is

RE: html:select few doubts

[Harland, David]

This is all you need





You can store your Collections in either the application/session/request/page 
scope. Be careful which one you store it in and what names you use as the key 
as the bean will check them all!!

property is the name you give to the select.
collection is any type of collection I use ArrayLists.
The objects in your collection must have a getValue method and a getLabel 
method.

The name value is optional. Only use it if you want to dynamically set the 
option in focus. The object who's key is "TESTSELECTOBJECT" in either the 
application/session/request/page scope must have a getTestselect method. If the 
value returned by getTestselect method matches a value in one of the options 
that option will be in focus.





Regards

Dave.

Hi All!

I've never used this tag before and I'm not so good with taglibs then 
please correct my mistakes if I commit any.

I got the following example in a recent thread here in this mailing list:


 



Ok, few things I could already understand, in the html:select tag there 
are 2 properties(in this case I know) name and property; name is the form 
name and property is a specic attribute in this form bean that is related 
to this field;

In the html:options we have name that is the form bean name, property is 
my collection, labelName is a field of my bean into the collection, and 
labelProperty is the final html option's value and also a field of my 
bean, right?;

does name in both tags can be directly found in any scope? I mean if my 
form is either in request or session, is it going to be taken? or am I 
missing something?

Property in the html:options tag can be any kind of Collection? can it be

RE: Test whether an application resource is empty

[Chris Loschen]

Hi Wendy,

Thank you very much for your reply.

Yes, I also thought that I could test the key, then check to see if the
value was empty. But just how to do it is eluding me. I think part of
the problem might be this:

USAGE NOTE - If you use another tag to create the body content (e.g.
bean:write), that tag must return a non-empty String. An empty String
equates to an empty body or a null String, and a new scripting variable
cannot be defined as null. Your bean must return a non-empty String, or
the define tag must be wrapped within a logic tag to test for an empty
or null value.

(from the Struts User Guide for bean:define at
http://struts.apache.org/userGuide/struts-bean.html#define).

I'm trying to do something like









 

But it's failing (I think) because the bean:message returns an empty
String. I would wrap it in a logic tag as suggested, but if I could do
that, I'd just use the same logic for my logic:notEmpty tag instead. So
finding a way to take that value and assign that to a variable which I
can then test to see whether or not it's empty is what I'm trying to do.

It was not my idea to add all of these empty i18n values: the i18n team
did it. If I can't find a way to make this idea work, that's my
alternate path. If that's the road I need to take, I can do it -- I was
just hopeful I could do this a little more elegantly.

Thanks for your input. Any further ideas?

Chris

If you can test the key, then it would seem that removing the empty
messages would solve the problem.  Why are the empty ones there in the
first place?

Are you accusing me in stealing your idea, or your code, or taking
credit for what you did? I already told you, that I did not see your
code before I wrote mine. If you want to believe in opposite, this is
your right to do so. Funny that you chose SelectAction for your
accusations, for it being just a dispatch helper.

The real deal is DialogAction, which packs several nice ideas into one
compact class. Again, I do not say that I invented something that
never existed. But I came up with these ideas myself. Careful search
on the internet revealed several blogs which discuss similar
approaches. This does not diminish what I did, and does not make a
thief out of me. I wrote the class and want it to be accepted in core
Struts. Plain and simple.

I already told you, that I do not use images, hence I do not know
what's the deal with ".x" and ".y". I wanted to use a plain pushbutton
with arbitrary caption on it, that is all. DispatchAction is so basic
that only a lazy dog have not tried to improve it.

I finally looked at your DispatchAction class. Obviously, it looks
similar, because the goal is similar. You do not use mapping from
request parameter to method, but I do. I think that indirect method
access gives more flexibility. You use dotted notation, I do not
anymore, because couple of times Struts threw an exception trying to
populate non-existent nested property.

I believe you misread what I wrote. By tricks I meant features of
DialogAction class, like (1) I/O separation in two phases using
POST/redirect/GET pattern, (2) using the same URL for redirected GET
to keep browser history from growing, (3) using non-cachable response
headers to avoid stale pages and to prevent resubmits, (4) creating
stateful object (a "web control") and rendering a page which
corresponds to its current state (think portlets for poor), (5)
storing messages in session for access after redirect. I don't think
that your DispatchAction has any of that. You do not even use
redirection in your mapping, and clicking Refresh button on your
sample web page invokes the infamous "Do you want to resubmit
POSTDATA?" dialog. This freaking dialog was the trigger, when I
started to think about I/O separation.

I have my own solution for (5), but  in DialogAction I use method
which comes in Struts, because it is easier. Still, I will probably
use my own solution, because current Struts implementation removes
messages from session after they were accessed, that does not really
work for me.

Why don't you submit your updated DispatchAction to Bugzilla? If it is
adopted in Struts standard library, I might rewrite my DialogAction
based on your code, there is no reason to multiply entities beyond
necessity. But mind you, that current Struts policy is to remove
@author tags from core classes.

Michael.

What's the point? Until there is an automatic tool that adds a useful

I don't see that

/**

Javadoc will automatically generate parameter names and types anyway.

Subject: Test whether an application resource is empty

Hi all,

I'm using struts 1.1.

I have localized application resources keys defined in my tiles
definition file. In my JSP, I use the tiles attribute and then display
the localized message using the key.

However, in some cases, the localized value is empty: there is no value
for that particular locale or that particular instance. In those cases,
I want to avoid writing out the key at all, but I'm having trouble
figuring out how to make that test.

Specifically, I have tiles defs like this:



Etc.


And the localized values are something like

tiles.main.admin.manageHierarchy.businessStruc.add.directionToUser=

(so no value for that key).  

In my JSP, I've tried several ways to test whether the key value is null
or the length is 0, but none of them have worked yet. For example:

 <% if(directionToUser !=
null && directionToUser.length()>0){ %>

<%
}%>

Problem here is that directionToUser is the key, not the value, so it's
never null, and I get the empty div tags I'm trying to avoid. So I tried
variations like this:











That one returned "Define tag can contain only one of name attribute,
value attribute, or body content". I've tried lots of variations similar
to that, but haven't struck upon the right one yet. This SEEMS like
something which should be pretty simple, but I'm missing something. Any
suggestions? Thanks!

[OT] Automatic Javadoc - ing

[Brian McGovern]

I have just pretty much wrapped up the development phase of a prject and am 
cleaning up the code etc.  I want to add javadoc comments to all my classes.. 
but am looking for a way to do this automatically.  Does anyone know of a tool 
that can do this.  I use netbeans as an editor and they have some limited auto 
javadocing.. but im looking to just press a button out put code and move on.  
There are hundreds of classes and i will NOT do this by hand.

Probabably should have been more diligent during development, but im a dope.

-thanks

RE: Problem with -- Help me OUT

[Ray Madigan]

Use the styleId attribute!  Frm the online API Guide

styleId

Identifier to be assigned to this HTML element (renders an "id" attribute).

N.B. If present, the errorStyleId overrides this attribute in the event of
an error for the element.

RE: Toggle Colors between Rows

[Nitin Mandolkar]

In action class which generate the table row out put 
Declare one temp variable which will you can use in decision making. 

Suppose you want to switch between colors red and green.
Code will be like this 

Byte switchcolor=0.

If (switchcolor=0) {
Row with red color.
Switchcolor++;
} else {
Row with green color.
Switchcolor--;
}

Any guess whats happening wrong here?,

the output is as follows

 4thCol 4thCol 4thCol 4thCol

But the correct output should be as follows

 1stCol 2ndCol 3rdCol 4thCol

RE: Toggle Colors between Rows

[McDonnell, Colm (MLIM)]

Some ideas ..

1. Implement a switching accessor method in a base action form, the idea
is that each time you access the property it will return the value which
was not returned on the prior invocation e.g. 

// In your base action form
private String listRowClass;

public String getListRowClass() {
if ( "odd".equals(listRowClass)
listRowClass = "even";
else
listRowClass = "odd";

return listRowClass;
}

<%-- In your JSP --%>
">

2. Use the current index number exposed by logic:iterate, if it is an
even number (e.g. divisible by 2 with no remainder) then use the "even"
style otherwise use the "odd" style. It might be possible to do the mod
calculation using a JSTL tag, if not it should be a trivial matter to
write a custom tag to do it for you.

3. Use a widget such as display tag and let that do all the work for you
:-)

Re: [ANNOUNCEMENT] Struts Dialogs: DispatchAction on steroids

[Dakota Jack]

I still am absolutely amazed that you "came up with these tricks"
without even knowing that the difficulty was that you could not
directly reference a name in name value pair because  includes
an .x and a .y with the name.  The code you duplicate exactly has been
based on solving that problem for ages and you do the same thing
without even knowing the basis for the solution.  That is very odd
indeed.  I would be inclined to think that you duplicated the code
without knowing why it was used that way and came up with the
description you did because that is the description on
www.michaelmcgrady.com and has been referenced to death by the struts
list.  But, as you say, you came up with these "tricks" and only later
discovered both the code that duplicates yours and the reason for the
code.  As I said, Michael, amazing!  Amazing!  You cannot pass on a
license to something you did not create or which is in the public
domain.

Yes but what about Netscape 4?   only kidding :)

The effect is neat however you do have to implement the no-cache and you 
have to turn off auto-validation and then rely on the browser, so I 
wonder whether it is really neat enough to be worth it.  I do prefer 
things to be as simple as possible, if not for robustness then just to 
make it easier for struts-newbies to take on board.

I don't understand how you managed to get the page with validate-error

to do with the browser history.



Pretty neat, huh? ;-) Does not look this slick on sucky Opera.

I turned validation off, so that action class is called even if input
data is not valid. Action must always be called, it does the
processing, it is a switchyard between GET and POST, it creates and
stores error and clears error messages, and it dispatches the request.

No-cache helps to reload a page. You can see in the sample app, that
without no-cache setting you need to manually reload a page to see
current server standing.

So, the page must be always reloaded to keep browser in sync with the
server. How exactly the history is kept from growing, is explained
further (almost quoting my own article, hence more formal style):

DialogAction uses a couple of tricks:

First is to serve different content from the same location. And by
saying "same" I mean exactly the same, including the number, names,
and content of request query parameters. Internet Explorer and
Mozilla/Firefox build session history based on resource location. They
do not include resources from the same location into the history. For
example, Login Control has two pages, "Not Logged In" and "Logged In",
each reflecting the web control state. Both pages are served from the
same location, which is the action URL. No additional parameters are
passed to action to trick the browser into thinking that it is the
same page.

Another trick is redirection: according to HTTP specs, when a browser
is redirected from a POST request, the resource identified by original
POST request must not be stored in the session history. Some browsers
like Internet Explorer go further and do not cache response for
original request even if the request has the GET type. This is how
initialization works, it uses GET with init parameter, and then
redirects to "clean" action location with no parameter, so browser
would not store URL with parameter in the history. Hmm, that seems to
work on Firefox too... I should re-read the specs ;)

Working together, these tricks result in a neat effect: a browser
thinks that it _keeps reloading the same page_. Thus, the browser
prevents a user from going back to see the stale data or to resubmit
the stale form.

If this approach does not work with a particular browser, and the
browser accumulates every page in its history, then the application
falls back to the Redirect-After-Post pattern.

The DialogAction was tested on Windows 2000 with Internet Explorer,
Netscape Navigator, Opera, and Firefox (make sure that you use the
official release of Firefox, which fixes the bug with no-store
cache-control header). Opera is the bad boy, it tries to cache
everything. It interprets the HTTP standard differently from Internet
Explorer and Firefox, and does not reload a page when a user navigates
back, even if page is marked as "no-store". Thus, it is possible to
resubmit a stale form from Opera. Sucky, sucky Opera.

For the record: I did not invent anything here. I mean, I did, I
reinvented the wheel, because after I came up with these tricks, I
googled specifically for this kind of stuff, and found several sites,
which use these tricks too. Still, it is not commonplace.

Michael.
