Re: [S2] Famoso Double conversion problem in S2 2.0.11.1!

[Bert Van den Brande]

I think this may be caused by this bug :
https://issues.apache.org/struts/browse/WW-3018

 No solutions ?

 Could maybe this be a problem, in this code:
 s:iterator ...
 ...
 s:url id=refUrl action=setValue
        s:param name=refValue1 value=refValue /
 /s:url
 ...
 /s:iterator

 refValue1 is of type Double in my action class, and I have DoubleConverter
 defined for its conversion, but my refValue is of simple type double, which
 is read from the list in iterator. When I click to this link, conversion is
 not invoked, why ?

 Thx, M.

 When generated in jsp, this link looks like this:

 \a id=c_5442.00 showerror=true targets=refValues
 dojotype=struts:BindAnchor href=# Set value 

 But when clicked nothing happes, it doesn't event came to conversion.
 (Note: I added \ before a because this forum show this code as a link
 only).

 Hi,

 I have again problem with Double conversion. I have a link in my page for
 double values:

 s:iterator ...
 ...
 s:url id=refUrl action=setValue
      s:param name=refValue value=refValue /
 /s:url

 s:a id=c_%{refValue} href=%{refUrl} theme=ajax
 targets=refValuesSet value/s:a
 ...
 /s:iterator

 In the form where refValue is entered I'm using my DoubleConverter
 conversion, and I checked with Firebug, refValue is set good, e.g.,
 c_4550.0. But when I click to this link above, I get 45500.0. Famoso zero
 is added!!

 Then I tried to define conversion properties for a class who have
 refValue attribute to my custom DoubleConvereter, but in this case click
 on the link Set value doesn't do anything! It is like a dead link.
 I checked also with Firebug and it is e.g., c_4550.

 What is the problem here and how can I solve it ?

Re: s:url - escapeAmp Problem

[Bert Van den Brande]

From the documentation : http://struts.apache.org/2.1.2/docs/url.html
escapeAmp : Specifies whether to escape ampersand () to (amp or not

So I guess in order to have the url showing  you need to set
escapeAmp to false ...

Re: Pls covert this code to struts 2.1

[Bert Van den Brande]

You assign the value 'documentTypes' to the property 'name' of the bean tag.

From the documentation : http://struts.apache.org/2.0.14/docs/bean.html
name = The class name of the bean to be instantiated (must respect
JavaBean specification)

So that is the reason for the ClassNotFoundException ...

 So, pls convert the code given below which was developed using struts 1.2 api

 The code is:

 property=referenceDocument.documentType size=1
   html:option value=-1Select/html:option

 Where- documentTypes is a list in the form named ReferenceDocumentForm.
 I tried converting the above code using struts 2.1 tags as given below:

 s:bean id=documentTypesCollection name=documentTypes/
 s:select label=%{getText('referenceDoc.type')} 
 name=referenceDocument.documentType required=true list=documentTypes 
 headerValue=select headerKey=-1 size=1 listKey=code listValue=desc/

 Where-documentTypes is a list with getters and setters in my action class

 When i run the application, I'm facing the problen shown below:

[ANN] May 20 - Writing JPA Applications by Patrick Linskey at Google in Silicon Valley

[Van Riper]

This is a free event open to the general public. So, please forward
this announcement on to other interested parties. The full meeting
announcement including directions to meeting site at Google in Silicon
Valley is here:

https://sv-web-jug.dev.java.net/servlets/NewsItemView?newsItemID=5601

Advanced Registration is required to be part of give-away drawing. You
can register at:

Agenda:
18:30-19:00 Arrive  mingle -- Food  drinks provided by Google
19:00-20:30 Writing JPA Applications Presentation

Description:
In this talk, Patrick explores the Java Persistence API, and examines
some common practices for how to write applications that use JPA.
Patrick will focus more on API usage than on mapping configuration,
and will look at the bootstrapping and runtime behavior of JPA
applications. You will learn about JPA's optimistic locking semantics,
including the benefits of optimistic read locks. Patrick looks at when
it's appropriate to use the different facilities of the Java
Persistence Query Language (JPQL), and also discusses common
extensions to the spec, including performance caching, pessimistic
locking, and fetch strategies.

Indexed nested beans

[Scott Van Wart]

Hi all,

I'm trying to get multiple levels of indexed, nested beans working.  
I've tried a variety of solutions but I keep getting xwork or ognl 
exceptions.  Here's what I've tried (loosely):


   public class MyAction implements Action, StrutsStatics {
 private ListPackageBean packages;
 public ListPackageBean getPackages() { return this.packages; }
 public ListPackageBean setPackages( ListPackageBean packages ) 
{ this.packages = packages; }

   }

   public class PackageBean {
 private ListElementBean elements;
 public ListElementBean getElements() { return this.packages; }
 public ListElementBean setElements( ListElementBean packages ) 
{ this.elements = elements; }

   }

   public class ElementBean {
 private String property1;
 private String property2;
 // getters and setters
   }

I refer to the properties in my inputs as 
packages[0].elements[0].property1.  When I POST, I get a 
NullPointerException in OgnlRuntime.getField (targetClass is null).


I tried using built-in arrays (PackageBean[] and ElementBean[]) and I 
get an OgnlException (source is null in setProperty( null, property1 
)).  I try initializing these to new PackageBean[0] and new 
ElementBean[0] and I get IndexOutOfBoundsException.


I tried pre-populating my collections (List...) with a few empty beans 
in both my action and PackageBean but I get the source is null 
exception again... I also tried the getPackage( int index ) and 
setPackage( int index, PackageBean pkg ) style getters and setters all 
the way through (initializing the lists with empty beans as necessary) 
with no success.


Am I way off on my thoughts of how nested beans and indexed properties work?

Thanks,
 Scott

[ANN-OT] February 19 - Stateful Applications that Scale Like Stateless Ones by Orion Letizi at Googleplex in Silicon Valley

[Van Riper]

Advanced Registration is required to be part of give-away drawing. You
can register at:  http://sv-web-jug.eventbrite.com/

 This is a free event open to the general public. So, please forward this
announcement on to other interested parties. The online meeting

18:30-19:00 Arrive  mingle -- Food  drinks provided by Google
19:00-20:30 Stateful Applications that Scale Like Stateless Ones
  talk by Orion Letizi

TALK DESCRIPTION
Within every innocent web application lies a sleeping monster. There
comes a time when every successful web application outgrows its
single-machine architecture. Whether for high-availability, scalability,
or both, the adult web application must grow to live on more than one
application server. That's when the latent beast strikes: the State
Monster. The most recent accepted wisdom about solving application state
problems in a scaled-out production architecture is to make your web
application stateless—i.e., externalize all application state out of
the application tier so that any application server can serve any user
request. Unfortunately for the owners of such applications, making it
stateless is hard to do, corrupts the programming and data model of
the application, and pushes the problem out to other pieces of
infrastructure that are ill-equipped to handle it. Stateless programming
is hard on the application developer, hard on the application
infrastructure, and hard on the application. There must be a better way
to write business applications. In this talk, we will discuss the
current stateless application paradigm, its shortcomings, and a new
alternative using Terracotta's open-source availability and scalability
technology for the Java Virtual Machine.

Please be sure to preregister at http://sv-web-jug.eventbrite.com/ so
you will be eligible for our raffle. We will be Using Jim Weaver's JavaFX
Spinning Wheel for our raffle. You can learn more about the project at:

Re: Every action is getting called twice

 What am I doing wrong?  Every request to an action goes into the actions'

This is going to sound unrelated, but, do you use Firefox browser with
Firebug enabled to test your code. I ran into one weird problem myself
where I was seeing double executions when Firebug was enabled. That
may not be the problem in your case, but, your symptoms are similar to
my situation where this was indeed the culprit. If you normally test
with Firebug enabled, disable it and try your test again to see
whether that changes things at all.

Good Luck, Van

Thank for your feedback,
But that release is used in my active project and I don't want to
upgrade it now. So have you ever get that error? is it be because of
struts version?
Thanks,

 Latest GA release is 2.0.11, you should really consider upgrading

Re: login and session

[Tuyen Dinh Van]

Hi,

You should use interceptors provided by struts 2 for authenticating the
user. The interceptor provide you with easy coding according to AOP.
You can take a look at the sample application accompanying with struts2
distribution, that is mailreader.

 Hello,

 I am starting to learn struts2 and I need some help.
 I have done a login form, if the loginAction returns SUCCESS I forward to
 a
 index.jsp, if it returns ERROR I forward to login.jsp page again.

 When the authentication is good I create a Session var called logged-in
 and
 I set it to true:

 Map session = ActionContext.getContext().getSession();
 session.put(logged-in,true);

 There is another action, the logoutAction, that remove the Session var.
 Then I have done a loginCheck.jsp file I include in the index.jsp in order
 to avoid unauthorized accesses.
 The loginCheck,jsp file looks like this:


 %@ taglib prefix=s uri=/struts-tags %
 %@ page language=java contentType=text/html import=java.util.*%
 html
 head
 titleCheck validate!/title
 /head
   body
  %
  try{

 response.getWriter
 ().println(DEBUG:+request.getSession().getAttribute(logged-in));
 if
 (request.getSession().getAttribute(logged-in).equals(true)){
 // do nothing!
 }else{

 response.sendRedirect(request.getContextPath()+/auth/login.jsp);
 }

 }catch(Exception e){
 //e.printStackTrace();
 response.getWriter().println(exception!);

 response.sendRedirect(request.getContextPath()+/auth/login.jsp);
 }

 %

 /body
 /html

 So, if the logged-in is setted to true, it's ok. Since the logged-in is
 removed if I try to access the Session it generates an exception so, if
 the
 exception happens I redirect to login.jsp page, but this redirect dosen't
 work. why? How can I did wrong?
 Can I also replace this code with the
 s:if test=#session.logged-in !='true'  redirect else do nothing...but
 it
 doesn't work too.

 So the questions are:

 1- why my redirection in the catch segment does not work? how can I handle
 it?
 2- writing the jsp code instead of struts tag is correct? Have I to use
 the
 s:if .. tags ??

 thanks
 lizzie

Re: Where to code getting user principal in struts based project

[Tuyen Dinh Van]

Hi,

I just guess your problem. If you have used struts 2.x, you can easily get
credential information via Action POJO. In your case, creating a new Action
named LoginAction with 2 properties username, password, then create a new
User class. In the LoginAction, get username and password passed in User
object, put it into session if authenticated.

Here is a piece of code for demo:

public class User implements Serializable {
private String username;
private String password;

public User(String username, String password)  {
this.username = username;
this.password = password;
}
}

Public class LoginAction {
private String username;
private String password;

public execute() {
User user = new User(getUserame(), getPassword());
}
}

 I read some info and it sounds like I should put this code in
 CustomRequestProcessor (which extends TilesRequestProcessor)'s
 processValidate method, please let me know if this is something correct.

Has anyone developed a web app using struts 2 and agegi security framework?

[Tuyen Dinh Van]

I am now developing my own management suite using struts 2, and I also
intend to use acegi for security, but very few document available for such
integration.

Has any one successfully integrated the acegi framework into struts 2?
Any suggestion is appreciated.

Thanks

Hi, Vinny
i also try urlrewrite but cannot get it work with struts 2's action,
only work with static html files.

would you pls give give me some sample app or guides to

Also, you might want to look at URLRewrite
http://tuckey.org/urlrewrite/  That is what I've been using in S1 and S2 
to

have
my urls  go from  this :  /myAction.do?p1=v1p2=v2 to
/myAction/p1,v1/p2,v2/

I'm also using the zero config and code behind plugins in struts2 that 
also

work to hide the extention.
I use urlfilter in addition to the plugins to customize the look of my url
parameters.

[OT] Silicon Valley Code Camp at Foothill College on Oct. 27-28

[Van Riper]

This is a free event by and for the developer community in Silicon
Valley. I've been promoting this event within the local Java developer
community. I'll also be leading one technical session at this Code
Camp based on my experiences converting to S2 from WebWork2 and the
ways we use S2 now in our consumer web site (krillion.com):

Details of My Sessions
http://tinyurl.com/35e4fo

Code Camp is a new type of community event where developers learn from
fellow developers. All are welcome to attend and speak.The Code Camp
Manifesto consists of six points:

(1) by and for the developer community;
(2) always free;
(3) community developed material;
(4) no fluff – only code;
(5) community ownership;
(6) never occur during working hours.

What can you expect at the Silicon Valley Code Camp?

Two full days of talking about code with fellow developers. Sessions
will range from informal chalk talks to presentations. There will be
a mix of presenters, some experienced folks, for some it may be their
first opportunity to speak in public. And we are expecting to see
people from throughout the Northern California region and beyond.
Attendance is free, but space is limited so you need to register in
advance. Here is the home page for the event:

http://www.siliconvalley-codecamp.com

It is not too late to signup to lead your own technical session too.
Session submission will remain open until about a week before the
event. After that, they will be assigning time slots at meeting spaces
to the submitted sessions based on the interest level expressed in
each topic.

Whether you to choose to present or just to participate, it would be
great to meetup with other S1 and S2 developers in the area at this
event. If you are interested, you can either respond to this thread or
contact me directly off list. If there is enough interest, we can
schedule an informal Struts BOF session during the weekend sometime
too.

Cheers, Van

Re: Struts - open windows without javascript

  how to open a new browser windows in Struts without to use

 Opening a new page is a client-side function. Since Struts is a
 server-side system, there's no way to do this.

 You could use the target attribute of the form... tag, which
 instructs the browser to open a new window for the result of the form.
 That's as close as you're going to get.

Same goes for the link a ... tag. The attribute you add to make your
form/link requests open a new browser window/tab is:

  target=_blank

Technically, this will open a new window without javascript. It is
just adding an HTML attribute to your form or link tags in your
generated HTML response. No javascript required.

 One caveat on the target attribute: it doesn't exist in xhtml 1.1.

Wow! I did not know that. Google to the rescue. Found this related
information online:

snippet
JavaScript window object solution:

Javascript provides a partial solution to the problem by passing the
href attribute to the window object's open method, and returning a
value of false. The false return from the event handler prevents the
web browser from following the link specified in the href attribute.

a href=http://www.TexaStar.com;
   onclick=window.open(this.href); return false;
   onkeypress=window.open(this.href); return false;TexaStar/a

This previous example provides an onclick event handler for those
using a pointing device, and an onkeypress event handler for those
using a keyboard. However, when JavaScript isn't enabled, the link is
processed as normal, providing a possibly adequate fallback mechanism,
but failing to produce the designer's desired result.
/snippet

So, it does require a small amount of javascript to make it work in an
XHTML 1.1 compliant manner. This snippet above comes from the
following online source:

 I'm wondering why they do that,



It looks like they have replaced ? = and  in the query string with letters, 
because search engines sometimes treat URLs with a query string differently.



 and how they do that?
 Can i also implement something like that?
Sure. You need to do two things. First change the characters in URLs that 
appear in HTML your application generates. In JSP or JSF you could use a 
custom tag for that. Second, in the web server use some kind of rewriting 
such as Apache mod_rewrite or a Servlet filter to translate the characters 
back again before they are used by your application.

The best workaround that I have found is to Just Say NO to the built

Hi,

I recently upgraded to struts 2.0.9, and now my tree viewer doesn't
respond to node selections any more.

Here's my jsp script: script function treeNodeSelected(nodeId) {
dojo.io.bind({ url: s:url
value='/tags/ui/ajax/dynamicTreeSelectAction.action' /?nodeId=+nodeId,
load: function(type, data, evt) {}, mimeType: text/html }); };

dojo.event.topic.subscribe(treeSelected, this, treeNodeSelected);
/script

s:tree theme=ajax rootNode=%{treeRootNode}
childCollectionProperty=childrenNodes nodeIdProperty=id
nodeTitleProperty=name treeSelectedTopic=treeSelected /s:tree

The action that's suppose to execute when a selection is made is
dynamicTreeSelectAction; but it never gets called (I use logging in the
execute() and setNodeId() methods)

Has anyone gotten around this problem?

  Something is wrong in your JSP... looks like that stack trace was cut off,

As Frank said, you have issues with your JSP. If you literally
cut/pasted your JSP logic into the email, then I can see at least two
separate problems with this snippet that would fail at compile time of
the JSP when converting it into a servlet.

You have scriptlet logic to start the for-loop and no matching
scriptlet logic to close the for loop. Even worse, your for-loop
iteration logic is totally whack. I am not saying this will fix it,
but, the for-loop will at least be properly closed and reasonably
defined when this snippet is changed from this:

select name=TVShowSelect
   %int i = 0;
   ArrayList ch = (ArrayList)
request.getSession().getAttribute(characters);
   String[] s = new String[ch.size()];
   ch.toArray(s);
   for (Iterator it = s.length; it.hasNext();) {
 String name = (String)it.next();
  %
option%=name%/option
   /select

To this:

select name=TVShowSelect
%  ArrayList ch = (ArrayList)
request.getSession().getAttribute(characters);
String[] s = new String[ch.size()];
ch.toArray(s);
for (int i = 0; i  s.length; i++) {
String name = s[i];
%
option%=name%/option
%  }
%
/select

I don't recommend this kind of scriptlet logic in the JSPs. If you are
going to do this though, you could at least try compiling the
scriptlet code in a test Java file first or use an IDE like IntelliJ
IDEA that will detect obvious compile issues with your scriptlet logic
in JSP files.

Good Luck, Van

Re: ActiveMQ Problem migrating from WebWork 2.2.2 to Struts 2.0.9

Yup! I had updated build process to exclude the spring plugin, but, I
never did a full rebuild that would have nuked it from my
distribution. Doh!

I'm not past this problem. I'm even see struts tags execute in the
JSPs forwarded to from my actions. However, I am now hitting my head
on a problem with the interaction of Sitemesh with Struts 2.0.9.  The
WW2.2 tags which have been converted to S2.0.9 tags which are working
fine in the main JSPs being evaluated are failing with an NPE on the
first struts tag encountered in my sitemesh decorator JSP file.

I'll start a new thread with a more appropriate topic for my current problem.

P.S. I already found the Wiki docs about sitemesh integration, but,
that was not enough in my case. :-(

supports templating:

http://struts.apache.org/2.0.9/docs/sitemesh-plugin.html

Until I added the ActionContextCleanUp filter, I was getting an NPE
for the first S2 tag encountered in my Sitemesh decorator JSP. My
final working web.xml filter settings/mappings (not using the
struts2-sitemesh-plugin though) are:


!-- This filter allows sitemesh decorator's to access struts
framework variables --
filter
filter-namestruts-cleanup/filter-name

filter-classorg.apache.struts2.dispatcher.ActionContextCleanUp/filter-class
/filter

!-- sitemesh gives us an overall page/panel definition --
filter
filter-namesitemesh/filter-name

filter-classcom.opensymphony.module.sitemesh.filter.PageFilter/filter-class
/filter

!-- Struts is attached as the last filter.
  Note that this must be placed AFTER other related filters
  (like SiteMesh) because if this succeeds and decides to send
  the request to struts, the rest of the filter chain is stopped.

I'm not sure why, but, I didn't need the extra cleanup filter for the
WW-2.2 app.

I may still run into some other minor hiccups during a full regression
test run, but, things are basically working now. This was done on a
SVN branch, but, I should be able to make the same changes in a matter
of hours (thanks to IntelliJ) on our main trunk later this week after
completing my regression testing on the branch. Phew!

ActiveMQ Problem migrating from WebWork 2.2.2 to Struts 2.0.9

[Van Riper]

I'm running into trouble migrating my existing web application from
WebWork 2.2.2 to Struts 2.0.9. We are using JSE6 (AKA JDK 1.6) and
Tomcat 5.5.17. I did everything mentioned on the wiki plus a bunch
more stuff:

http://struts.apache.org/2.x/docs/webwork-2-migration-strategies.html

If I ever get this working I promise to provide feedback to update
this page based on my experiences migrating to Struts 2.0.9. To set
things up, I was fairly quickly able to get to the point that I had a
clean build of my webapp after swapping out WebWork and swapping in
Struts 2.0.9. Hard as it may be to believe, we were not using Spring
IoC. I had that turned off in my webwork.properties like so:

### Configuration for IoC Container
### webwork.objectFactory=spring

However, it appears that S2 really wants some IoC container because I
kept getting complaints with this commented out. So, I uncommented it
in my renamed struts. properties file (added necessary listener in
web.xml too) and included the latest Spring Framework jar file
(2.0.6). This in turn gave me complaints about missing ActiveMQ
classes and including the main jar file for latest ActiveMQ (4.1.1)
didn't seem to help. That catches everyone up to my current situation.
Here is the full console log output for my latest failed webapp
startup:

I don't think you need struts 2 support to do this. I'm using webwork
2.2 currently and starting to monitor this list again in preparation
for migrating our webapp codebase to struts 2. We also use Sitemesh
for response decoration. So, our Sitemesh decorator sets the base
element for our response during the execution of sitemesh response
filter. The way we do it in JSP land is:

base id=docBase href=%=request.getRequestURL()%/

No webapp framework support required. We give the base element an id
because we have some javascript functions that need to access the base
document  URL dynamically. This makes it easy to do the element lookup
by id via Javascript elsewhere.

Generic Selection Screen

[Michel Van Asten]

Hi,

I need a generic selection screen in my application.

By Selection screen I mean 

1° Two html select one for selectable items
And an other for selected items
2° five buttons copy copy all remove remove all an d confirm.

Very basic code... 

I just want to avoid copy paste the code for all the numerous list...

One of the possibility is to use a general purpose property for the list... 
Just filled before display... But that's not very clean any other idea ???

expression evaluation

[Michel Van Asten]

Hi,

I have a list of user... 
I want to display some details and add two input images near each of
them with edit and delete action associated...
I planned to add a javascript to store the name of the clicked image in
an hidden field.

The problem I have is that the name I will get back is an expression
users[0].uid Is there a standard or clean way to evaluate such
expression at server side ?



nested:iterate property=users 
tr
td align=left width=15%nested:write property=uid//td
td align=left width=25%nested:write
property=name//td
td align=left width=50%nested:write

I'm guessing there are a fair number of Java web developer from

here. Although the primary topic is Flex, it is being discussed in the
context of integrating this technology with web applications written

Not using S2 yet, but, WW 2.2 that S2 is based on has tag themes for
the form tags. You can write your own theme extensions of base form
tags to follow your convention for form field layout. I'd be surprised
if that capability was lost in the merger. You can look at the xhtml
theme as an example. It might even do something close enough to what
you want already. I seem to recall that it layed out form fields as
table rows with label in one column and field in adjacent column of
same table row.

Design

[Michel Van Asten]

Hi,

We have to developp a new application and we want to with a good design.

Basically we have a set of functionalities (user management, user data control, 
user data conversion, ...) the availabilty of those functionalities is 
controlled via a dynamic menu.


Hi planned to define one action for each functionality. 
But for the menu whats the best solution ?

I see two solutions :

1° Adding an extra action for the menu and implement Action chaining if I need 
to jump back to the menu.
2° All the actions extends a base class wich implement menu management routine 
and I use global forward.

RE: render trademark symbol

[Van Nguyen]

OK... so I've been playing around with this for the pass day.  

1. I don't want to store the trademark symbol as trade; in my lucene index.
2. I could write a method to detect the TM symbol and then encode it to trade; 
and then use the filter=false in the bean:write tag.

But is there a more elegant way about this?

   Subject: render trademark symbol


   Hi,



   I'm using struts 1.2.9 and am running into a problem rendering the 
 trademark symbol using the bean taglib.



   I have this string stored in my lucene index as:



   W.RoseT Convex Jointer



   It stores it in my bean as such. but when I use the bean:write tag, it 
 displays it as:



 W.Rose? Convex Jointer








   I added some breakpoints in the WriteTag class inside the struts library, 
 and I see that it comes in as



   W.RoseT Convex Jointer



   And it is being returned as the same string.



   Is there anything else that needs to be done to render the Trademark symbol 
 as T?



   I've read online that HTML needs it to be trade; to render correctly.  But 
 I've tried changing the text in the bean to:



   W.Rosetrade; Convex Jointer



   But that did not work either. the bean:write tag just displays it as 
 W.Rosetrade; Convex Jointer



   Any suggestions?

Oracle AS jsp:setProperty problem, Struts alternative?

[Scott Van Wart]

Is there a Struts (1.3.5) alternative to the jsp:setProperty tag?  
jsp:setProperty works fine when it's close to the jsp:useBean tag, 
but when it's farther down the page, Oracle's JSP translator might put 
the setProperty translation in a separate method than the bean 
declaration in the output .java file.  Kind of like this (simplified for 
sanity):


 public void renderPage() {
   MyBean bean;

   bean = pageContext.getAttribute( ... );
   doTag();
 }

 private void doTag() {
   bean.setValue( ... );
 }

Which obviously doesn't work.. but the translator doesn't know this. :)

Re: Out of topic, Oracle SEQUENCE

[Scott Van Wart]

In PL/SQL:

 DECLARE
   new_user_id NUMBER;
 BEGIN
   INSERT INTO users ( user_id, user_name ) VALUES ( user_seq.NEXTVAL, 
'userName' ) RETURNING user_id INTO new_user_id;

 END;

So, similarly (though a little bit of a hack), in JDBC (since 
generatedKeys() or whatever they call it isn't supported, though been 
promised since Oracle 7-8?):


 // context: con is a java.sql.Connection
 CallableStatement stmt = con.prepareCall( {call 
   + INSERT INTO users ( user_id, user_name ) 
   + VALUES ( user_seq.NEXTVAL, ? ) 
   + RETURNING user_id INTO ?} );
 stmt.registerOutParameter( 2, java.sql.Types.NUMERIC );
 stmt.setString( 1, userName );
 stmt.executeUpdate();
 long newId = stmt.getLong( 2 );

A few things,
 - Whitespace can be detrimental to the prepareCall statement.  Don't 
put any spaces in {call.
 - Specify the column list before VALUES--Oracle won't guarantee 
column order across databases.

 - Get yourself a nice persistence layer (Hibernate?) :).

HTH,

Re: empty fields of an input form get default value after submitting

Sandra Reichert wrote:

Hi,

I have an input form in jsp. After submitting empty fields (user entered

But i want to have a null value for empty fields.
Or in other words: How can i decide if for example the 0 is entered by

This is one of the many reasons you should prefer String-valued form 
bean properties, rather than using int/Integer, etc. That way, you can 
redisplay incorrect/invalid inputs for the user to edit and correct. 
What if the user types 'two' into a field that's backed by an 
Integer-typed property? Resetting it to 0 is clearly not what you 
want, but resetting it to null isn't great either.


If you don't care about redisplaying input values and/or you really 
can't change your form properties to be String-typed, the best you can 
do it to re-configure the BeanUtils converters to use null as a 
default instead of 0.


I use Long/Integer for hidden, state fields that the user won't 
see/can't change.  I've been thinking of using them for option... 
values as well, since the user can't see those either.  Idea being that 
the only way the user can change these values is by editing the HTML 
source.  If they do that, all bets are off :).  As long as it doesn't 
muck up the application.  Though I should probably point out the people 
who are using my web apps are the same people who requested it, and no 
more.  Things would obviously be a little different on a public web site 
if a user managed to edit someone else's profile by changing something 
like input type=hidden name=userId value=4 to another number on 
the system :).

Struts uses the name attribute to repopulate your form on submit.  So 
if you have an action /someAction mapped to a form bean named myForm, 
it should look like html:form action=/someAction, and thus form 
name=myForm  So in your JavaScript you can refer to document.myForm.

Extending tag libraries

[Scott Van Wart]

This is a little OT, but it, uh, kind of has to do with Struts :).

I'm interested in adding a few attributes to some of the struts tags.  
They're really only useful in the context of a specific web project I'm 
working on, so I'd really prefer not to edit the Struts TLD and 
implementation (for various other reasons too :).


Problem is, a lot of these have to do with view/layout, so I wanted to 
use .tag files.  Everything's fine if I extend a single property, say 
html:text property=blah /:


 %@ attribute name=property required=true type=java.lang.String %

 html:text property=${property} /

Problem is, there are a lot more attributes, most are optional, and 
different permutations, etc.  Is there a relatively easy way of doing 
this in .tag files?  Do I have to use tag classes and, if so, is it 
possible to tell the JSP processor to re-compile the stuff I output so 
it doesn't write html:text property... / verbatim to the client?

Re: Creating new Session without invalidating the old one

[Scott Van Wart]

[EMAIL PROTECTED] wrote:

Hello!

Is it possible to create a new session for an already logged in person (which
has an actual session) without invalidating the existing session? It's necessary
for me to have the old session before creating an additional one, because I have
to get few datas from the old session for the new one.

request.getSession(true) gives a new session, but only if the user doesn't have
an existing session.
  
OK this is an odd one, but I'll give it a shot.  It seems like you want 
to transfer information from one session to another.  So I'll offer up a 
hypothetical situation.  You want a login dialog to pop up when the 
user's session times out (let's say after 15 minutes).  After about 60 
minutes the user decides to log back in, and you want session 
information to persist.


Aside from this, I honestly can't see any reason why you'd need to have 
two sessions open.  If you absolutely must, find a medium where you can 
persist the data (even if it's just serializing the objects to a file).  
If you didn't want the session to timeout in the first place, then don't 
set the timeout so low!  You can set session timeout on a per-session 
basis with HttpSession.setMaxInactiveInterval.  Combine this with 
HttpSessionListener and you can set up a mechanism with different 
timeouts per session, or with the appropriate authorization Action (a la 
struts) and have a timeout-per-user mechanism.


At this point I'm just speculating.  You'll need to give a reason _why_ 
you want to do this, because a lot of people (including myself) seem to 
be under the impression that you're working at the wrong solution to a 
problem that might not exist.

Re: HttpSession facade

Madhav Bhargava wrote:

I was going thru the struts source code and was in particular reading the
way they have implemented the synchronizer token pattern for preventing
multiple submits on transacional pages.

I saw that they have synchronized on session ID attribute. Is it possible
that multiple session share the same session ID? There is noting in the
servlet API that mandates it.
All I know is from tinkering around in the source myself.  I think the 
idea behind a session facade is to provide a bridge between your typical 
session (want a session, get a session), and expected behavior in a 
clustered or multi-VM environment.  In the latter case you might have 
two physical computers that process two different requests from the same 
user (with the same ID).  The session needs to be serialized and sent 
between computers so each computer behaves as if they know about the 
original session equally well.  Rather than sending every bit of session 
information to every machine (or in smaller environments, every 
process), the session facade handles management of session information 
in case this session information needs to be shared with another provider.


Wow, that was fun.  Anyways, while two or more users WON'T share the 
same session ID, the stuff still needs to be synchronized.  One web 
request might be writing information to the session while another is 
trying to read it to service a subsequent request from the same user.

Depending on your IDE (I use Eclipse), you might be able to factor out 
the casts into separate methods, and add the @SuppressWarnings(

 public void myFunction() {
   current.setUserRights( (TreeSetInteger) )this.userRights.clone();
 }

You'd have a helper function:

 @SupressWarnings( unchecked )
 public TreeSetInteger cloneUserRights( UserRights rights ) {
   return (TreeSetInteger)rights.clone();
 }

And use this method accordingly.  Keep in mind that you should probably 
be absolutely certain about the real type of the object when you do 
this.  The whole generic thing is simply syntactic sugar (the runtime 
still does the casts), and the warnings are there as a reminder.

My java standalone application wants connection to database with lookup  to datasource name which is configured in the oc4j app server.

You need to bind it yourself, to some provider.  I use the DBCP provided 
with Tomcat (naming-factory-dbcp.jar); the context factory is 
org.apache.naming.java.javaURLContextFactory (that's not a typo, the 
class name begins with a lowercase letter). Then you create your 
InitialContext, create sub contexts for each component and bind your 
object to the last context.  DBCP is an in-memory one that seems to beat 
the beta fscontext reference that Sun released.


Oracle has a class 'com.oracle.naming.J2EEContext'.  I suspect that's 
what OC4J uses.  It also seems to have 
com.evermind.server.rmi.RMIInitialContextFactory.  See if you can find 
javadocs for those.  If you're grabbing a DataSource remotely from a 
running OC4J instance, I did a quick google search and found 
http://www.oracle.com/technology/products/ias/toplink/doc/1013/MAIN/_html/cachsyn007.htm 
.. it's for TopLink, but it uses JNDI and follows the same conventions 
that your standalone OC4J (or app server) is going to use--JMS or RMI 
(corba).

[1.3] Session ActionMessages won't go away

[Scott Van Wart]

Hi, I have something very close to the following in each of my pages 
(actually, just in the layout page for tiles, but whatever).  Worked 
fine in Struts 1.2.9 (even though I'm not so sure it's the best way to 
print messages and errors, but oh well...)


   logic:messagesPresent message=true
   bean:message key=header.notice /
   ul
   html:messages id=message message=true
   libean:write name=message //li
   /html:messages
   /ul
   /logic:messagesPresent
   
   logic:messagesPresent message=false

   bean:message key=header.error /
   ul
   html:messages id=error message=false
   libean:write name=error //li
   /html:messages
   /ul
   /logic:messagesPresent

I store my messages in the session so they'll persist even after a 
redirect.  Unfortunately, in 1.3, when I call saveMessages( 
request.getSession(), messages ), the message appears properly, but 
continues to appear on subsequent page requests.  Any ideas?

Re: [OT] request.getServletPath() val not same in Filter Servlet

Hello,

Sorry for posting this in Struts mailing list but I can't seem to get an
answer on any other discussion groups. I've always had great results getting
good answers here so here goes...

I have a Filter in my app that uses the request.getServletPath() method to
get the name of the page being invoked without the context path.

This worked fine until I try to invoke a servlet. For example, if I invoke a
url like http://localhost/app1/servlet/package.ServletName the result of
calling request.getServletPath() is '/servlet'.

However, if I make the same call when I'm in the servlet the result is
'/servlet/package.ServletName'

Why does it give a different result in the filter and the servlet?

Thanks!

  

AHH! http://tomcat.apache.org/faq/misc.html#invoker

Use a different prefix or path for your servlets than servlet, no 
matter how tempting it is.

Hi Scott,

I  added a unspecified() method in my action class and it works now.
I am not able to understand though how it is working, unspecified() is

I have a parameter name= navigation and its value is shown as {submitText}.
But it calls unspecified  method, for that value as it would have done if

I am assuming it is calling unspecified() because  it is not able to find

the key name {submitText}
  

I hope I read your reply correctly.

You should NEVER EVER see {submitText} when you're stepping through 
Java, or in the log window, or in an exception stack trace!!!  The ONLY 
place it should appear is in your JSP.  In ALL OTHER PLACES, you should 
see the text that you put in your MessageResources.properties.  If 
you're seeing {submitText} verbatim, then your JSP compiler is 
ignoring EL, or it's not written correctly.  For this line in your JSP,


 hiddenField.value = ${submitText};

Go ahead and request your page in your browser, then go to view source.  
Scroll down to where this line should appear in the HTML, and make sure 
it says something like,


 hiddenField.value = Next;

instead.

Now there might be a workaround... I gave you the EL method because I 
find it much cleaner than embedding XML-like tags in JavaScript, but the 
following may also work in your JSP:


hiddenField.value = 'bean:message key=button.next /';

This might work... I don't LIKE it, because it's an XML (tag library, 
whatever) tag inside JavaScript inside HTML in a JSP... but oh well.  
Note the quotes -- the outermost are single quotes, the innermost are 
double quotes.  Double check them even if you copied/pasted them just to 
get into the habit.


If you were using {submitText} in your post as a placeholder for the 
actual text that should appear to the browser, my apologies, though I 
hope you understand what I was getting at :).


If this WAS the case, since you're not using EL, feel free to remove the 
lines I gave you in an earlier post,


 c:set var=submitText
   bean:message key=button.submit /
 /c:set

As you don't need them.

Creating a DynaBean from an ActionForm on the fly

[Scott Van Wart]

Is it possible to get a DynaBean object from an ActionForm 
programmatically?  I need to create a copy of a form, but cloneBean 
isn't working.  I have a map-based nested bean (which lets me do stuff 
like 'myform.child(ABC).name), but cloneBean does a SHALLOW (argh!) copy 
of the map so the original and the clone have the same map values.

If you mean extending DispatchAction, your execute() method will get 
called.  Unless you have a call to super.execute() (which then calls 
DispatchAction.execute()), your class will pretty much behave like a 
regular Action class, which kind of defeats the purpose of extending 
DispatchAction in the first place.


If you need to do special processing before any of your methods are 
invoked, an idea is to override execute(), do some processing and ensure 
you call super.execute() somewhere appropriate.

Couple of things to check:

- In struts-config.xml, make sure your package names and class names of 
your form-bean ... and action... tags are all spelled correctly, 
including case.
- Do the same for your ActionForm and Action classes, and make sure 
they're in the packages you expect them to be in.
- As a last resort, try cleaning the deployment context (undeploying), 
then clean-build your project and redeploy.


In short, it's probably a typo.

Re: Form Validation

[Scott Van Wart]

Chetan Pandey wrote:

Is their a way to specify multiple inputs.
  


Nope.  A wise man once told me that validate=true is there only for 
convenience.  So the workaround is to do something like 
'validate=false', omit the input= tag, and add forwards like,


action...
 forward name=add path=page.add /
 forward name=edit path=page.edit /
/action

public void create( ActionMapping mapping, ... ) {

 ActionErrors errors = form.validate( mapping, request );
 if ( errors == null ) {
   errors = new ActionErrors();
 } else if ( !errors.isEmpty() ) {
   saveErrors( errors );
   return mapping.findForward( add );
 }

 // Do some stuff

 // ... and success!
 myForm.setId( someObject.getId() );
 return mapping.findForward( edit );

}

So if it passes validation and everything checks out okay, it goes to 
the edit page to the newly added record.  Otherwise it goes back to 
add.  You can do the same thing for delete (ie: if you were editing a 
record, but suddenly lose the state of the record you're editing because 
the user is mucking about).


This gives you more power over when and how to do validation, and what 
to do on pass/fail (sometimes you might have to repopulate a few of the 
ActionForm's values--which is something else you can't do with the 
validate=true shortcut).

[SOLVED] Re: Auto render form bean as hidden fields

[Scott Van Wart]

In case anyone's curious, here's the synopsis of my solution:

- Manually annotate (Java 1.5) the private fields I want to track.
- Have a base class that stores the original state (when a record is 
first loaded from the database, for editing, for example).
- Write a class that walks through the annotated fields, getting their 
type from attributes (types are things like 
simple--hidden,text,etc--nested, or mapped), and writes input 
type=hidden... tags for each one.
- Make a tag library to output the JS (exporting page context variables 
is a magical thing indeed) for checking for changes.

- Unit test for a few days :)

The tricky part was the map-based nested beans.  The easy part was 
outputting the input type=hidden... tags.  The hard part was 
realizing that BeanUtils.cloneBean does a shallow copy of Maps.  
Fortunately, the code that walked through the annotations was also able 
to deep-copy the bean.

Re: Question about Lookup dispatch action

[Scott Van Wart]

mosho wrote:

Request[/planName] does not contain handler parameter named navigation
  


In your struts-config.xml, are you including 'parameter=navigation' in 
your action mapping?  A la:


 action path=/planName type=my.pkg.PlanNameAction 
name=planNameForm parameter=navigation

...
 /action

The parameter gives you a place to pass additional data to your action.  
In the case of LookupDispatchAction, it uses it to find out which 
request parameter (in this case, navigation) it should look at to 
determine which method to call in your subclass.  So your form will 
submit, and be stuff like:


 navigation=Next%20Record

It looks messy, but that's OK.  The framework takes it and translates it 
back into Next Record.  Now in your subclass, you override 
getKeyMethodMap() right?  And somewhere in there, you have something like,


 map.put( navigation.next.record, next );

Where next corresponds to the public ActionForward next( 
ActionMapping...) method you have defined in your subclass.


And in your MessageResources.properties (or whatever the file's called 
in your web app), you have:


 navigation.next.record=Next Record

See how everything links together?  Now the button text you choose is 
likely different, but this flexibility is the reason you NEVER refer to 
the button by its text.  Let Struts do that internally, only your users 
should see it.  Just thought I'd give you a little background so you 
know what you're getting into; anyone correct me if I'm wrong :)


Oh one last thing.  Make sure you're NOT overriding execute() in your 
subclass.  It's fine for regular Action-derived classes, but you're 
using LookupDispatchAction, which needs to run its own implementation of 
execute().

And as he's using LookupDispatchAction, the value=submitText would

Well first you should probably get rid of 'value=Previous', since you 
should be (and are) setting the button text using bean:message.../.


I didn't consider you were using regular buttons as well.  In this case, 
the hidden field is going to be sent, and might muck up 
LookupDispatchAction when the user clicks a regular button.  So what you 
might need to do is something like this:


 input type=hidden id=hiddenNavigation name=navigation value= 
disabled


I can't guarantee having the disabled there will work, but it should 
prevent the web browser from sending an extra (blank) navigation 
property and possibly causing the bean helpers to discard the REAL 
navigation value (when a button is clicked).  Then in your JSP:


 c:set var=submitText
   bean:message key=button.submit /
 /c:set

 script type=text/javascript

   function onClickSubmit() {
 var hiddenField = document.getElementById( hiddenNavigation );
 hiddenField.disabled = false;
 hiddenField.value = ${submitText};
 document.navigationForm.submit();
   }

 /script

Originally rendered.  I need to render the hidden fields because it's a 
multi-user system, and I have other mechanisms that maintain 
concurrency--so by passing the fields back and forth as hidden, the 
process doesn't get disrupted by someone else changing it in the 
background (I can use my other methods of notifying the user that this 
has happened).
Even then, all you really need is a Javascript object containing 
key/value pairs describing each form property's starting value. You 
shouldn't need to worry about server-side data types, collections, or 
anything else; just 'form field X has value Y'.


There are a few things I need to worry about by design:
- Child items listed on a page, and their order.
- Multi-select dropdowns.
- Multiple checkboxes (this one actually wasn't as difficult as I 
thought it was going to be).
- Map-based nested beans (someForm.someChild(4).whatever--ahh, a simple 
key=value?  Nope, whatever is a multi-checkbox).


Right now I'm halfway through my implementation of generating a lot of 
stuff myself.  Rather than using beanutils, I just add a @NavPrompt 
annotation to each private member of my ActionForm that I want to 
track.  I've implemented basic ones (where I can just do 
document.form.whatever.value != ...), multi-selects (with a helper 
method), multi-checkboxes (with a helper method), but I still need to do 
nested beans and map-based beans.


I decided to do it this way rather than simple key/value pairs to keep 
the JavaScript as simple as possible.  It's also possible that with 
better knowledge of JavaScript I could reduce the amount of framework I 
need to write on the server, but writing Java code is far more fun than 
learning--let alone writing--JavaScript IMHO :).

I have another requirement now, I have multiple images that are going to be

So in my javascript, I will have to submit the form. How can I change/ set

It is giving me error:
Request[/selectLocation] does not contain handler parameter named navigation

Thanks for your help,



In your onclick handler for the images, change the (presumably) hidden
form input field value:

  document.forms[form-name].elements[navigation].value = new-value

Then, submit the form.

This is in Firefox.  Looks like it works for IE as well.

Not really a Struts question -- just straight Javascript...
  

Doesn't he need to match up the message resource values, like if he had,

 protected Map getKeyMethodMap() {
   Map map = new TreeMap();
   map.put( form.create, create );
   return map;
 }

Then it would take a little trickery in the JSP to get the right values 
in the Javascript:


c:set var=createLabel
 bean:message key=form.create /
/c:set

So the web browser passes the correct value, and the lookup map will work:

function onClickCreate() {
 document.someForm.action.value = ${createLabel};
 document.someForm.submit();
}

That should do it I think...

LookupDispatchAction using wrong resource bundle!

I have multiple resource bundles in addition to the default one in

 message-resources parameter=MessageResources null=false /

 !-- I put id, parameter and key, because I'm not convinced I know 
what each one does :( --
 message-resources id=constraints parameter=constraints 
key=constraints

   factory=ca.indosoft.common.resource.ConstraintResourcesFactory
   null=true /

In my Action:

 protected void create( ... ) { ... }

 // and so on...

 protected Map getKeyMethodMap()
 {
   final MapString, String map = new TreeMapString, String();
   map.put( form.label.create, create );
   map.put( form.label.update, update );
   map.put( form.label.delete, delete );
   map.put( form.label.clear, clear );
   map.put( form.label.cancel, cancel );
   map.put( form.label.new, makeNew );
   return map;
 }

But when I debug through it, in LookupDispatchAction.initLookupMap( 
HttpServletRequest, Locale ), it's using the 
ConstraintResourcesFactory!  The only place I actually say 
'bundle=constraints' is in my validation.xml, which doesn't get hit at 
all (my app fails because LookupDispatchAction is looking in the 
ConstraintResources class, and not MessageResources.properties):


 form name=myForm
   field property=title depends=required,maxlength
 msg name=required key=error.title.required /
 msg name=maxlength key=error.title.overflow /
 arg name=maxlength bundle=constraints key=title.length /
   /field
 /form

Is this a bug, or an issue with my implementation?

different compared to the 1.1.X branch.  If you correct the problem to the
Resources class you might want to submit it to JIRA.
  

http://svn.apache.org/viewvc/struts/struts1/trunk/core/src/main/java/org/apache/struts/validator/FieldChecks.java?revision=289694view=markup

This is the first revision with the resource support (2005 Sep 17).  
Struts 1.2.9 was released 2006 Mar 22, but doesn't include this!

Re: LookupDispatchAction using wrong resource bundle!

[Scott Van Wart]

LookupDispatchAction checks ALL the resource bundles (and doesn't even 
stop when it finds the key).  Does anyone see any reason why it can't 
use the same mechanism as everything else, or has this been fixed in a 
later version?

Auto render form bean as hidden fields

[Scott Van Wart]

We have a requirement that the user be prompted if any changes have been 
made on a form, and they try to navigate away.  I've divided this up 
into sub tasks:

- Iterating through properties of a bean.
- Render properties as hidden fields.
- Render some JavaScript to check for modifications.

The last one's going to be the tough one, but it's manageable.  Before I 
start writing some custom tags, I was wondering if Struts or its 
dependent libs had any of this functionality already.  I'd likely need 
some type of property class, and a way of discerning, in JSP tags 
(preferable), if a property is nested, a collection, a boolean or a 
string.  I think those four types should cover it.  I've no problem 
writing the facility myself but I'd hate to duplicate work that's 
already there.


Thanks,
 Scott

Re: Validator Client-Side and Custom Classes

[Scott Van Wart]

Hi,
I want to do client-side validation using a custom class I can specify in
the validator.xml validatorclassname//validatior section. But my
question is if I use a custom class, then how the heck can Struts 
generate
the custom javascript for it in the jsp if I'm using a custom java 
class I

wrote that exists only on the server?  Not possible right?

So if that's the case, if you do leave some custom classname validator 
class

in your validation.xml, then will that validation simply be ignored?

Thanks for help with these 2 questions.

If you look at the source for commons-validator, you'll see a package 
called 'org.apache.commons.validator.javascript'.  It has a bunch of .js 
files as package resources, so you might look at the sources for those 
to get started.  Beyond that I don't have any experience with it (I 
personally can't stand client-side validations, as validation has to be 
done in the database, and on the server side, and I feel inclined to 
draw the line somewhere given a choice :).


The 'validateUtilities.js' seems to have a lot of functions that the 
other .js files make use of, so you should probably do so as well.  It 
also looks like the .js file name, and function name inside the file 
match the method name of your validation routine (with a 'form' 
parameter passed, which is likely an array?).  So if you do all this, I 
would imagine the validator will pick it up automatically (and fail 
silently and ignore it if you don't, as you mentioned above).


Good luck,
 Scott

Re: Forwards between webapps

Re: What's the difference between struts-base and struts-el?

[Scott Van Wart]

Michael Cheung wrote:

Hi, all;

What's the difference between struts-base
to struts-el.
  

My general understanding is:
- struts-el is so you can use EL expressions in your Struts tags without 
having to use servlet 2.4.  The JSP compiler won't compile the EL, so 
it's up to Struts to do it.  Use the regular Struts taglib if you know 
your JSP compiler supports EL.
- Servlet 2.3 supports EL, but is disabled by default (you need 
isELIgnored=false or something like that at the top of every JSP).

- Servlet 2.4 has it enabled by default.
- You can disallow % (java) % stuff in your JSPs by specifying it in 
your web.xml in Servlet 2.4
- JSTL 1.0 is used when you don't have EL support--same reason why 
Struts provides struts-el.
- JSTL 1.1 is used when you DO have EL support, so the JSTL doesn't need 
to handle EL itself.

- Not sure about the c-rt.tld you refer to, I haven't encountered it.

I suspect all these confusing differences are the result of an emerging 
technology.  Java's resisted this whole dynamic programming thing (I 
hear Mustang's going to push the envelope, however), so the EL was a bit 
of a workaround that's now being adopted as people update their servlet 
containers.

Map-based nested bean--No bean specified?

[Scott Van Wart]

I posted on this before, so I thought I'd post a more concrete example 
this time.


I'm using a map-based nested bean, and I'm getting the following error:

java.lang.IllegalArgumentException: No bean specified

org.apache.commons.beanutils.PropertyUtilsBean.getPropertyDescriptor(PropertyUtilsBean.java:751)

org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:937)

org.apache.commons.beanutils.BeanUtilsBean.populate(BeanUtilsBean.java:811)
org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:298)
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:493)
(add nausea)

So I whipped up an example.  I have a DoTestAction that populates the 
form and sticks it in a request.  The form is called TestForm and looks 
like this:


 package test.form;

 import java.util.Map;
 import java.util.Set;
 import java.util.TreeMap;

 import org.apache.struts.action.ActionForm;

 public class TestForm extends ActionForm
 {

   public static final long serialVersionUID = 1;

   private String firstName;
   private String lastName;
  
   private MapString, ChildPerson children;
  
   public TestForm()

   {
 this.firstName = ;
 this.lastName = ;
 this.children = new TreeMapString, ChildPerson();
   }

   public SetString getChildIds()
   {
 return this.children.keySet();
   }
  
   public MapString, ChildPerson getChildren()

   {
 return this.children;
   }

   public void setChildren( MapString, ChildPerson children )
   {
 this.children = children;
   }

   public String getFirstName()
   {
 return this.firstName;
   }

   public void setFirstName( String firstName )
   {
 this.firstName = firstName;
   }
  
   public String getLastName()

   {
 return this.lastName;
   }
  
   public void setLastName( String lastName )

   {
 this.lastName = lastName;
   }

   public void setChild( String id, ChildPerson child )
   {
 this.children.put( id, child );
   }
  
   public ChildPerson getChild( String id )

   {
 return this.children.get( id );
   }
  
 }



The populate action looks like this:

 package test.action;

 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;

 import org.apache.struts.action.Action;
 import org.apache.struts.action.ActionForm;
 import org.apache.struts.action.ActionForward;
 import org.apache.struts.action.ActionMapping;

 import test.form.ChildPerson;
 import test.form.TestForm;

 public class DoTestAction extends Action
 {

   @Override
   public ActionForward execute( ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response )
 throws Exception
   {

 TestForm testForm = new TestForm();

 ChildPerson child = new ChildPerson();
 child.setFirstName( First 1 );
 child.setLastName( Last 1 );
 testForm.setChild( 1, child );

 child = new ChildPerson();
 child.setFirstName( First 2 );
 child.setLastName( Last 2 );
 testForm.setChild( 2, child );

 request.setAttribute( testForm, testForm );

 return mapping.findForward( default );


   }

 }

While the JSP itself looks like this:

   %@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
   %@ taglib uri=/tags/struts-html prefix=html %
  
   %@ page language=java contentType=text/html; charset=UTF-8

   pageEncoding=UTF-8%
  
   !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN
  
   html

   head
   meta http-equiv=Content-Type content=text/html; 
charset=UTF-8

   titleTest/title
   /head
   body
  
   html:form action=/test
  
   First Name: html:text property=firstName /br
  
   Last Name: html:text property=lastName /br
  
   c:forEach var=childId items=${testForm.childIds}
  
   Child #${childId} First Name: html:text 
property=child(${childId}).firstName /br
  
   Child #${childId} Last Name: html:text 
property=child(${childId}).lastName /br
  
   /c:forEach
  
   html:submit /
  
   /html:form
  
   /body

   /html

My struts-config.xml (though I'm not sure this would help) has this for 
the forms and actions:


   form-bean name=doTestForm
   type=test.form.DoTestForm /

   form-bean name=testForm
   type=test.form.TestForm /

   ...

   action path=/doTest type=test.action.DoTestAction 
name=doTestForm scope=request

 validate=false
 forward name=default path=/test.jsp /
   /action

   action path=/test type=test.action.TestAction name=testForm 
scope=request

 validate=false
 forward name=default path=/test.jsp /
   /action

I won't bother to post TestAction (/testAction) as it doesn't even get 
to that point.  Am I doing this the right way?  Is this sort of thing 
even possible?  It seems such a natural way 

[SOLVED?] Re: Map-based nested bean--No bean specified?

[Scott Van Wart]

OK so I replaced the 'getChild( String id )' method with the following:

 public ChildPerson getChild( String id )
 {
   ChildPerson child = this.children.get( id );
   if ( child == null )
   {
 child = new ChildPerson();
 this.children.put( id, child );
   }
   return child;
 }

And my problems were all solved.  I tried this solution before in my 
previous post, but made a typo, which caused it to fail with the same 
error, so I thought my previous solution simply didn't work.  It wasn't 
until I tried this solution with my concrete example below that I 
noticed the typo (was creating a new child, putting it into the map, but 
then STILL returning null.  Note that setChild( String id, ChildPerson 
child ) never gets called by the framework.


So my final question: Is all this a good idea? :)

Map-based nested bean

[Scott Van Wart]

(Struts 1.2.9, Tomcat 5.5.17)

I have something similar to the following in my ActionForm:

   public class MyForm extends ActionForm {

   public static class NestedBean {
   private String name;
   private String value;
   // String getName(), String getValue(), void setName( String 
), void setValue( String )

   }

   private MapString, NestedBean children = new TreeMapString, 
NestedBean();


   // Map getChildren(), void setChildren( Map )

   public NestedBean getChild( String key ) {
   return this.children.get( key );
   }

   public void setChild( String key, NestedBean child ) {
   this.children.put( key, child );
   }

   }

I use it like so in the JSP:

   html:form action=/myAction
   html:text property=myForm.child(whatever).name /
   html:text property=myForm.child(whatever).value /
   /html:form

Everything works fine until form submission.  Then I get errors like No 
bean specified in the populate methods of BeanUtils.  Looking at the 
property descriptors I see that it's not picking up the getChild and 
setChild accessors.  Is this the right way to implement this?  Am I 
still missing something?

Re: Accepting multiple date masks with the date validator

[Scott Van Wart]

Adam Gordon wrote:

IIOC, the only way you can do this with the stock validator is to use mask
rather than date as the validator.  Then, you can use a regex to dictate
your mask.  I'll warn you though, if you use a regular expression it's going
to be VERY long because it will also need to validate that the date entered
is valid.  Additionally, the stock date validator accepts dates like 30 FEB
 and just rolls it to the appropriate March date.  Here's the REGEX we
use (note that the regex is all on one line with no spaces:

var
  var-namemask/var-name
 
var-value^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(2

9|30)|(0?[13578]|1[02])/31)/(20)((0[6-9])|(10))|0?2/29/((20)(0[48])))$/var-
value
/var

Alternatively, you can override the validate method in your ValidatorForm
and do it yourself - which given your requirements, sounds like the easier
of the two options.
  

Holy lipton that's nuts.  I think I'll see what's behind door number 3:

public void setDate( String date )
{
 this.date = translateDate( date ); // where translateDate inserts the 
slashes if necessary

}

So I can use the date validator with no problems, and when the client 
submits the form, they get back a slash-separated date in the input field.


Thanks for the help :)

In your bean setter for the date, I'd make sure no exceptions could be 
thrown, or handle them - the code I took over from an engineer we had 
that left had this issue and it took me almost a week to track down 
what was going on between the validator and his code.
Yeah, essentially I'm covering all the bases (null pointers, index out 
of bounds, etc.) so no RuntimeExceptions can be thrown either.  If 
anything doesn't look right to the translation method, it simply returns 
the original.  I DO like regular expressions, but feel that a lot of
