Re: Struts URLs for perfectionists like Ebay's URLs

[Vo Van Thuong]

Hi Vinny,

I'd like users to access to my website by URLs like Ebay's:
http://listings.ebay.com/_W0QQcoactionZcompareQQcoentrypageZsearchQQcopagenumZ1QQfromZR2QQftrtZ1QQftrvZ1QQsabfmtsZ1QQsacatZQ2d1QQsaobfmtsZinsifQQsocmdZListingCategoryList
In which we can't see which one is get parameters which one is value 
obviously.


I've already read an article at 
http://www.lunatech-research.com/archives/2005/07/29/struts-urls
Which gives guides to remove the request extension (.do), the parameter and 
value from urls.

eg:
   customer.do?method=edit&id=42
   /customer/edit/42

Thanks for quick response.

hi all,
i want to set the value of a datetimepicker in javasript but
  

encounter


a problem. i do that like this: first use ajax to
get a record as a "json" object,then use the "json" object to initialize
  

a


form, which contains a datetimepicker.
the form is used to add a new record and to modify a select record.

the main code is as follows

//the datetimepicker i want to set value,the   is
included in the head tags.


//the js to set value of datetimepicker
 function modify()
{
var vDate = dojo.widget.byId("validateDate");

 vDate.setValue('2007-01-01');

 alert(vDate.getValue());

}
the value do be set because the 'alert(vDate.getValue())'  shows the
  

value


'2007-01-01',the problem is the input box of the datetimepicker displays
nothing,and i couldnot select a new date either,something like the
datetimepicker is disabled,( is included in the
  

head


tags,the datetimepicker works well when add a record in the form)
does anyone knows how to handle this problem?
many thanks.

Re: can't cast an object back from session

[meissa . sakho]

Yes, when I try casting it like you this,
 User user=(User)getSession().get(Constantes.USER_SESSION_KEY);
I'm getting a ClassCastException.
The debugger clearly shows me the right name I'm waiting for.
It's very strange.

Re: can't cast an object back from session







Did you try casting it directly, like:

User user=(User)getSession().get(Constantes.USER_SESSION_KEY);

?

If not, try logging (or debug to it) the class name of the object you've
got:

getSession().getAttribute("aa").getClass().getCanonicalName() (or 
getName())

Loggers and debuggers are great for this...

Roger Ye wrote:

Hi Frank,

I'm interested in the experience with DWR and Dojo you have got,
so why are you trying to move away from Dojo? then move to which?
is is DWR?


Let me begin by giving the caveat that we started with Dojo 0.3.1, and 
have never had the time to upgrade, so we're still on that version. 
We've also had to make quite a few custom mods (not just a custom build, 
actual Dojo code changes) to it to get it to do everything we needed, 
which makes upgrading that much harder.  For reference, we're using 
dojo.io.bind, plus some widgets (tab, calendar, button, floating pane 
and menu).  We used to use the button widget too, but swapped that out 
for performance reasons, believe it or not!


We're moving away from Dojo because of one realization: it's better to 
build with best-of-breed products than to try and grab one do-it-all 
product.  We choose Dojo initially for two reasons.  One, it was gaining 
a lot of steam at the time we made the decision, and two, because of the 
nature of our development team (they had no RIA development experience 
and didn't have a ton of Struts experience either), we felt it would be 
better to have one library that did everything we needed.  We decided we 
wanted to use Struts (1.2.7) because there was at least *some* 
familiarity on the team with it, so we needed to find some method of 
AJAX that could co-exist with it, so DWR wasn't the best choice at the 
time either.  And really there was a third reason: there was no dominant 
Javascript/AJAX library really, but Dojo seemed to be on its way to 
becoming that (and still may be), so there really wasn't a *whole* lot 
of choice, given some of our challenges.


And since someone is bound to ask, we considered AjaxParts of course, 
would be crazy if we didn't consider the project I started!  We decided 
against it because the nature of the app we were charged with building 
would have required a ton of custom handlers to be coded, and when you 
get to that point, the benefits of APT start to melt away.


We had our problems with Dojo along the way ranging from performance to 
bugs to missing features.  But again, to be fair, we're talking about a 
fairly old version at this point.  We overcame all of these, and the app 
is very highly regarded now, so the choice hasn't actually hurt us in 
any big way.


The drive towards DWR is coming from me specifically because it starts 
you down a path of an architecture that makes a ton of sense to me: 
best-of-breed widgets and support libraries on the client, and nothing 
but POJOs on the server.  No framework like Struts to learn, no 
complicated Javascript to learn (at least for the remoting part of the 
equation) and very quick turn-around times because writing a POJO is 
quicker than anything Struts can offer (and the less said about EJBs, 
even 3.0 beans, the better).  Mix in the right widgets and you can get 
an incredibly rich webapp up and running in almost no time at all.


I'm also introducing Spring to a lot of people little by little (and 
learning it myself little by little), as part of our developing 
reference architecture, so we get a lot of benefit there too, and it 
integrates nicely with DWR.


We're finding that a lot of the things we thought would be problems, 
like the desire to have method-level access control like you get with 
EJBs, is not much more work in this model.  There are still some 
challenges of course (like not having il8n automatically like you can 
have with Struts), but overall it's working out very well.



I've used DWR in a previous project, for me it's quite good, gotta love it,
however, in the current project we use Struts 2 and Struts 2 seems to have
some connection with Dojo, so I appreciate a lot if you could share your
story with Dojo.


I can't talk intelligently (as if that ever stops me!) about the AJAX 
support in S2 because I only have some "playground" experience with 
it... I've yet to use S2 in a real project that wasn't contrived for my 
own benefit... then again, with this simple DWR-based architecture 
gaining steam, I may never have to.  Ironically, S2 does a lot of what 
we did in our project: abstracts away the details of Dojo.  We pretty 
much built an API around Dojo so that our more junior developers barely 
knew they were using Dojo.  Some of this was taglibs (especially where 
widgets were involved), other parts of it was a Javascript API that is 
more business/function-oriented, so for instance, instead of having to 
worry about how to do an AJAX call with Dojo, you instead call our 
submitFormTargetTab() method, and that would deal with all the details 
and put the results in the specified tab on the screen (plus it deals 
with a lot of other related things that don't have to do with Dojo).


Well, that's my .0006 cents on things.


Thanks
Roger

RE: [struts2] Button pressed

[Jason Wyatt]

Hi Marcos, 

In my understanding you can use a String instead of a boolean:

Action:

private String submit;

public void setSubmit(String submit) {
this.submit = submit;
}

And in the JSP:

 

 


Note there is a bug in 2.0.9 that this doesn't work for ajax-themed submit
buttons.

Hello

I've tried following this

in my validate() method of my action to check wich button was pressed, It
doesn't seem to work though.

private boolean selecaoOk = false;

public void setSelecaoOk(boolean selecaoOk) {
this.selecaoOk = selecaoOk;
}

And in my jsp:



But when the form is submitted the selecaoOk variable is false.

Has anyone succeed in determing wich button was pressed with Struts2.0.9?

Any tips?

Re: [OT] Ajax recommendations for use with Struts1.1

[Frank W. Zammetti]

Hi Rick,

AjaxParts is still a good alternative, especially given your past 
experience.  It's still very much alive, and probably even a bit better 
than the last time you used it.


As Adam said, DWR is another alternative I think very highly of as well 
(highly enough to be nearing completion of a book about it).


We've used Dojo at work with good success, although I've always had a 
little bit of unease with it (and we're actually trying to move away 
from it little by little), but that shouldn't dissuade you from checking 
it out (especially if you just need AJAX out of it, I think you could be 
OK with it).  Prototype is always a good option, very minimal and easy 
to use.


I'd personally look at what you want/have to do... if you still want to 
stay away from Javascript as much as possible, that's always been an 
area that AjaxParts excels in (and I think doesn't have too many rivals 
in that regard frankly).


If you have some leeway though, you can have a very compelling 
architecture with DWR and Spring mixed in.  You find that you really 
don't need any framework at all, and the code you write is very elegant. 
 This is the direction I'm pushing at work, and I'm getting some 
traction given some early successes with the concept.


With the restrictions you have though, AjaxParts might be your best bet, 
especially if keeping the Javascript you have to write to a minimum is 
something important to you.  It'll still I think require the least 
amount of effort to work with Struts 1.1 your using, require the least 
amount of change to anything that may already exist.  DWR leads down a 
different path, and most of the other options, I believe, don't really 
offer anything all that different from one another.  There's always GWT 
too, although if you have to use Struts I'm not sure what integration 
options there are (nor am I sure you could use the older JDK version). 
I'm not aware of any other options that would, were I in your shoes, get 
me all that excited.

struts1 taglibs and struts2

[Adam Hardy]

The old struts1 HTML taglibs have a 'titleKey' attribute, for putting an 
internationalised title on an HTML tag automatically. Others had a 'key' attribute.


Is there any intention to put this kind of attribute onto the S2 tags? I know 
there are OGNL methods to do the same thing, but 'titleKey' is so elegant.

Adam

Hi Rick,

DWR is highly useful for getting your pojos across to the client-side and back

[struts2] Button pressed

[Marcos Mendonça]

Hello

I've tried following this
http://struts.apache.org/2.x/docs/html-form-buttons-howto.html, to
determine in my validate() method of my action to check wich button
was pressed, It doesn't seem to work though.

private boolean selecaoOk = false;

public void setSelecaoOk(boolean selecaoOk) {
this.selecaoOk = selecaoOk;
}

And in my jsp:



But when the form is submitted the selecaoOk variable is false.

Has anyone succeed in determing wich button was pressed with Struts2.0.9?

Any tips?

Thanks

Re: can we redirect to input page after validation fails ?

[Paul Benedict]

To preserve messages across redirects, you need to do a little magic.

Struts 1.2 does not have the automatic ability to put messages into session
scope if validation fails. Instead, you should customize the Controller
(through a subclass you write) to copy any messages from the request into
the session if they are unaccessed. You should customize processValidate to
do something similar:

ActionErrors errors = validation.
if (errors are found) {
  if (errors are unaccessed) {
create session if necessary;
copy them to session;
}

This will be a standard part of the upcoming 1.4 release.

Hi!! your method works..but i am not able to see my error message..
i mean.. i want it to work like javascript... like display the err mesg when 
validation fails, and once i refresh the page, display the page without error

may seem like i am greedy.. but i just want to know if it is possible..

You can do it, but it's a little bit more work.

Hi to everybody.

I have a JSP that has a Tree that is modified by a submit button that sends

Inside this ActionForm class, the tree is modified but only if the page is 
reloaded the tree is visually modified.

How can I reload the page after de mapping.findForward sentence?

Re: [s2] Odd taglib behaviour with single character comparisons

[Chris Pratt]

Not sure where, but I remember reading that OGNL converts single
characters in single quotes to the Character wrapper type, which may
explain what you're seeing.  In the first case "1" != '1' in Java
since one is a String and one is a char, same is true here.

Was there anything in the logs about 3 & 7 throwing exceptions?
That's the only reason I can think of that they wouldn't print.

Re: can't cast an object back from session

[wild_oscar]

Did you try casting it directly, like:

User user=(User)getSession().get(Constantes.USER_SESSION_KEY);

?

If not, try logging (or debug to it) the class name of the object you've
got:

getSession().getAttribute("aa").getClass().getCanonicalName() (or getName())

Loggers and debuggers are great for this...

Re: Struts tags help

[wild_oscar]

Not really. 
I stumbled upon this doubt when developing my application.
I have a List of Principals on my session. The first element is a
UserPrincipal and the rest are RolePrincipal.
What I want is to simply have in a JSP:

Welcome, USERNAME

And I want to retrieve USERNAME from that list. Which, in Java, is something
like Principals[0].getName()

or iterate through the principals List, see if the Principal is of instance
UserPrincipal and, if true, return the current principal's name.

On a general idea, I'm trying to find:

1) How to retrieve an item from a List using OGNL

2) What's the best approach for getting users info on JSP pages, either:
   a) Getting them like 

  b) Developing a custom JSP tag to get these kinds of information (name,
email, etc). This would also be an exercise, as I have never developed a
custom JSP tag library.


So, any feedback on questions 1) and 2) would be great!

can't cast an object back from session

[meissa . sakho]

I'm troubleshooted with this starnge behaviour of the session.
I have implemented SessionAware and have defined a session attribute of 
Map type with getter (and setter)
as indicated to handle session.

I'm putting a User objet to the session and want to retrieve it after some 
steps.
The code below gives me an Object that is already well typed.

Object user=getSession().get(Constantes.USER_SESSION_KEY);


I'm seeing the object  but when I try to Cast it, like that

user=(User)user;

 I'm getting a ClasscastException.

What am I missing here ?
why can't we cast objects from the session.

Following the latest message, what is the syntax if your session attribute is
a List of Principal objects and what you want is an attribute in

a) the first object in the list ( principals[0].name)

b) the first object of the child principal Principal1
(principal1Object.name) ?

Re: How to handle validation/errors in Ajax requests

[Musachy Barroso]

There isn't much you can do about that on 2.0, on trunk (future 2.1)
we have a new JSON validation interceptor, check this for details:

Request Processing Chains - HOWTO... ?

[Arne Brutschy]

Hello,

I'm new to struts 1.3.x and therefore not used to the new request
processing using common-chains. I have two questions:

How do I filter/add request parameters? "In the old days" (TM) I
simply added a filter, which wrapped a RequestWrapper around the
non-writable map. How can I do that now? The structure of the context
isn't quite clear to me, and I don't know where to set the new request
wrapper object...

Second question is connected (= me not knowing where to set things):
Suppose I have authentication checker, which is called through the
servlet-standard-preprocess chain as shown here:
http://www.onjava.com/pub/a/onjava/2005/03/02/commonchains2.html
So when the filter detects, that the user isn't logged in yet, I want
it to redirect/forward to some /login.jsp. How do I do that know?

I think I haven't got the internal structure of the request processing
yet. And informations on the process/how to use and expand it are hard
to get.. Any hints?

Execute Action on the server

[Oguz Kologlu]

Hi,

Does anyone know how to execute an action on the server and get the  
result on the server (without having to use something like commons  
http client).


What I want is the resulting html from an action so I send it as an  
email. I vaguely remember a way to do it with a velocity template I'd  
prefer to keep it in jsp.


Thanks,

Re: [S2] action mappings help

If you are trying to truly redirect then the below line is your problem.  It
is trying to forward not redirect.
""

Use:

<%
String redirectAction = "/myapp/subfolder/welcome.action";
response.sendRedirect(redirectAction);
%>

How to handle validation/errors in Ajax requests

[Marc Eckart]

Hi,

I start a ajax request with a 

This pumps the result in the target div tag and all is perfect. But how can
I handle validation errors.
They should not appear in the target div tag, instead it should appear in a
different div tag for errors.
Can I change the target or can I force the site to load complete instead of
just the (with ajax) requested part.
In case a exception occurs, can I redirect to an error page? Now the error
page appears instead of the result in the target div.

Any suggestions?

Thanx in advance.

[s2] Odd taglib behaviour with single character comparisons

[Mark McLaren]

I hope someone can explain the following behaviour to me.  Using the
S2 taglibs and OGNL is starting to confuse me somewhat.  I have a test
JSP that I am accessing via the default ActionSupport class:

<[EMAIL PROTECTED] uri="http://java.sun.com/jstl/core"; prefix="c"%>
<[EMAIL PROTECTED] prefix="s" uri="/struts-tags" %>














 If I call my page via  "test.action?input=1".  I get:

   1. true
   2. true
   3. false
   4. true

   5. false
   6. false
   7. false
   8. false

Why is result 3 false?  If I then call my page via
"test.action?input=a".  I get:

   1. false
   2. false
   3.
   4. false

   5. true
   6. true
   7.
   8. true

Why are the result of 3 and 7 results now blank?  I have no idea what
is going on here, is this a bug?

It seems to only happen when I'm evaluating against a single
character.  I'm guessing it is some kind of char to String comparison
problem.  It would feel very odd if I had to start using single quotes
around my taglib attributes (I usually need double quotes for
XML/XHTML attributes).

Thanks,

Mark

Re: [S2 and Ajax] Could not locale widget implementation...

[Paolo Beccari]

Follow up, just in case...

The two problems where related one each other. In fact:

Taglib 
<%@ taglib prefix="s" uri="/struts-tags" %>

was defined in the "main" page.

Inside the jsp called via Ajax by action result (inside s:div) I used tags
like s:property.

I discovered that when doing


the page called by the action result has to define another taglib prefix:
<%@ taglib prefix="another" uri="/struts-tags" %>

This way all things works fine:


gives the expected result.

[S2] action mappings help

I'm trying to create an index with an action mapped to it for a 
subfolder in my webapp. The ideea was to create a index.jsp file that has:



so it redirects me to a mapped action. The problem is that even though 
the url is correct, i get a
"The requested resource (/myapp/subfolder/welcome.action) is not 
available" from my server.


If i point my browser to http://website/myapp/subfolder/welcome.action 
(ie: if i type this in) everything works out just fine. What am i doing 
wrong?

Displaying table contents

[Hiroyuki Suzuki]

Hello guys..
Please help me in displaying the contents of the table.
I have the following in my database:
3 radio buttons (siteName/siteSequence)
each siteSequence has the following select options 
(siteTemplate/siteTemplateSequence)
Example:

siteName  siteSeqsiteTemplate  siteTemplateSequence
X  1 A,B,C   1
Y  2 D,E,F   2
Z  3 G,H,I3

For every siteList(radio button), it will display the corresponding
siteTemplate

Now I have this code in my JSP

 
   
  
 
   
 
 
   ${template.siteTemplate}
 

   
   


In the above code, the 3 buttons are displayed and each has their select
options, but the contents of each options
does not corresponds to each siteSequence, instead it displays all the
siteTemplate for each select options
(A,B,C,D,E,F,G,H,I)..

How will I connect the siteSequence to the siteTemplate so that it will
display only the corresponding siteTemplate for
each siteName?

Please help me..

Hiro

Re: Struts138 - Restrict Access to my actions?

[Paul Benedict]

Thomas,

But you're using Struts 1.3.8 right? The interceptor solution is for Struts
2.

I once thought of adding an "internal" attribute to my Struts actions. If
the action had this property set through , then the Controller
would not allow the action to be executed directly (i.e., through the
address bar). The only way it could be accessed was if the action was
internally forwarded or included from a request.

Does this sound similar to you?

Paul

Re: struts 1.3.5 problem
