RE: Problems with multibox and checkbox

[Jörg Maurer]

Hi Jason! 

reading through your mail, i got especially attracted on your solution
combining XSLT with struts tags. I am currently doing some after-project
considerations, having been my first struts project(and also the first
for my actual company, hence having no one to having an expertise talk).
One action point on my list is the question : "How to control which
model elements map to which view elements and vice versa(especially at
runtime)." 

So i would be a great honour for me if you 

- can write me a few words because of out of what considerations you are
using XSLT and struts tags.

- devote a second of your precious time to my topic "How to control
which model elements map to which view elements and vice versa" - if and
how XSLT can help me to come up with a more generic solution. E.g. I
would like features as described in struts-layout ( taken from
http://struts.application-servers.com/) "Let's image you are running an
online shop selling books. There is one jsp to display information about
the book (title, author, size, price etc.). The customers can only view
the information, but the site administrator can view and modify the
information. Normally, you would have to make two jsps to achieve that:
one to display the information, and one to modify them (you can also
make one jsp with complicated logic stuff in it). With Struts-Layout, it
is possible to make only one jsp, without logic in it.The goals is : One
user object to create / edit / view, one DistpachAction class, one Form
class, and one jsp." - but i don't like that taglib approach very much,
because it is becoming too cohesive to the dependent frameworks.


Thank you so much for your inputJörg Maurer

I orginally thought the problem was with struts, but it seems to be an
xsl
problem I am having.   I am generating many struts forms using jsp/xml
syntax and struts.  It is working quite nicely so far.  I am using
,,... with no problems, but for some
reason my xsl style sheet renders  or 
without
html prefix.

I found the problem for anyone who may need an answer.  It was nothing
to do
with checkbox or multibox.  Since I was calling this from within and XSL
template, I needed to declare the tag library in the xsl style sheet as
well
as the jsp:root.

I have tried both of the following, but I can not get this to work.




I have a group of checkboxes that I would like to have filled after a
validation attempt.
If I add either of the following I get the following rendered to the
browser.
I have radio, and text fields working fine.




What am I missing?
Do I need to set chkItems to zero length in the form reset() method?
If so, what is the syntax?

RE: how to catch exception using tiles thrown by e.g. org.apache.struts.tiles.TilesUtilStrutsModulesImpl.doInclude

[Jörg Maurer]

Wondering why i have no chance to catch any exception i did some
investigation on that topic , so i consulted the java logic of your
insert tag. it is that ~good~ shielded against any exception bubbling,
that my own error handler logic never gets a chance because ALL
EXCEPTIONS HAVE BEEN CAUGTH AND NEVER RETHROWN. next is snip from your
Insert Tag(commented out is your code, underneath that is what i want -
throw new JspException(ex.getMessage())) : 

} catch (ServletException ex) {
Throwable realEx = ex;
if (ex.getRootCause() != null) {
realEx = ex.getRootCause();
}
//  processException(
//  realEx,
//  "[ServletException in:" + page +
"] " + realEx.getMessage() + "'");
throw new JspException(ex.getMessage());
} catch (Exception ex) {
//  processException(ex, "[Exception in:" +
page + "] " + ex.getMessage());
throw new JspException(ex.getMessage());
} finally {
// restore old context
// done only if currentContext not null
(bug with Silverstream ?; related by Arvindra Sehmi 20010712)
if (currentContext != null)
pageContext.setAttribute(

ComponentConstants.COMPONENT_CONTEXT,
currentContext,

pageContext.REQUEST_SCOPE);

}
return EVAL_PAGE;

Looking at Geary´s template insert tag, he always chose to do "throw new
JspException(ex.getMessage());".

Your logic displays by default a simple stack trace(Exception type and
exception message) of where the tile should be. I dont want to show that
to my customer, but as i said, i have no change to display my  jsp-error
page instead.  

So if that "feature" is not here for any other reason, i consider that
being a unlucky design for me, because i have to at least vesion my own
tiles.jar or do some dirty subclassing your tag.

I would appreciate your comment.

  This make sense: Your page is made of several tiles. The first ones 
have already been compute, and so some outputs have been flushed. Then, 
one of the  throw an exception. This exception is not catched

by the jsp mechanism because the output stream has already been flushed

Hi,

I am using nested:checkbox for  a boolean property.
Unfortunately, struts is not setting the property of the

when I check the box , struts set the property correctly. Any
clue?

RE: How do you keep your session junk free?

[Jörg Maurer]

AFAIK, why not put form bean in hashtable under well known name in
application scope - last resort, cause as you mentioned request not
applicable, session not available you are in full charge of form
bean. populate that bean in application scope as you like from newly
created form bean or replace it all at once. Have to e.g. prepend key
with user information(getSessionID()) to get same bean for user back?

How do you prevent the session from filling up with junk from previous 
screens?  Or to put it another way:

I have written some screens that have to store the form bean in the 
session scope as each screen is interconnected and uses the same 
instance of the form bean.   If I change the scope to request a new form

bean is created for each screen (every time a jsp file is rendered).  Is

there a way of implementing multiple screens with the same form bean 
with a request scope?

RE: List-backed properties

[Jörg Maurer]

Hi hans !

As my best practice, the thing missing is following : 

in any action form is a reset method per subclassing action from.
1st-class use of reset for me is to set every action form instance
variable to some initialising state. so what is the initialising state
of an array list? exactly, first of all the number of the elements you
want to fill in.

how do we know how many of these elments will there be? because we
queried our database before and remembered the count of records in our
action class. with this knowledge, call reset with the count - but hold
- there is no parameter to give to reset!

So i made in every action from class my own reset method called
myReset(int prepare_for_count) - 2 advantages : 
1.)as reset() is called always by framework(after each new request), i
can´t manage session state in action form with this solution. exception
to this case is well known checkbox problem. so i am in full charge of
when and how myReset() is called.
2.)i can inform myReset of prepare_for_count value.

so inside myReset(int prepare_for_count){ //there will be something like

values = new ArraList();
values.setSize(prepare_for_count);

}

after that call, i fill in data from my result set in action form.

1 disadvantage : i have to take care of THAT i call myReset().

Hope that helps Jörg

Subject: List-backed properties


Hello all,

I am a little bit confused about an example for list-backed properties:

The documentation at 
http://jakarta.apache.org/struts/userGuide/building_controller.html
contains the following example in section 4.3.2:

public FooForm extends ActionForm {

 private final List values = new ArrayList();

 public void setValue(int key, Object value) {
 values.set(key, value);
 }

 public Object getValue(int key) {
 return values.get(key);
 }
}


As "values" is initialized as empty ArrayList, any call to values.set 
causes an IndexOutOfBoundException to be thrown.
(see also: 
http://java.sun.com/j2se/1.4.1/docs/api/java/util/ArrayList.html#set(int
,java.lang.Object) 
  )

Therefore, I cannot imagine how that example could ever work.
Could someone please explain me that discrepancy?

Thanks in advance,

Hans

  I suppose that your exception is thrown by a  tag in

a jsp.
  This exception is thrown by the tiles framework, which know nothing 
about the struts exception mechanism, so it can't be used. The exception

is then propagated by the tag handler and reach the jsp page (the tile 
jsp). If there is an exception handler associated to the jsp, it is 
called, if there is no handler, the exception is propagated to parent 
page inserting this one. If the parent page have inserted the child page

with an , then the  catch the exception and show it.

Normally, the jsp exception handling should work, but it appear that it 
is not always the case.

  A workaround is to put a big try/catch in the jsp throwing the 
exception ;-(. This will be improved in future versions.

how to catch exception using tiles thrown by e.g. org.apache.struts.tiles.TilesUtilStrutsModulesImpl.doInclude

[Jörg Maurer]

Hi struts people!

I have really defined everywhere i think i can put an exception handler
for servlet exception : 
1.) in my base layout.jsp an <%@
errorPage='/pages/common/error/errorsGeneralHandler.jsp'%>
2.) in struts config a global exception handler
 

  
3.) in web.xml
  
javax.servlet.ServletException
/pages/common/error/errorsGeneralHandler.jsp
  

Still ServletException slip through my guards. Last know point as stack
trace shows below is
org.apache.struts.tiles.TilesUtilStrutsModulesImpl.doInclude(TilesUtilSt
rutsModulesImpl.java:122) , which throws ServletException but is never
catchable to me. The point is not the FileNotFound, which is pretty
clear to me, but why such exception doesn´t hit any of my error handler.

Any hints appreciated!

Question using transactional tokens

[Jörg Maurer]

Let me sketch my problem to you - using for the first time transactional
tokens, i have the following setup :
1. in my jsp :

...


2. where submitSelect is a javascript function:
function submitSelect(method) {
document.forms[0].method.value = method;
document.forms[0].submit();
}

3. and in my action class subclassing dispatch action there is method
save().

Following strange behaviour (to me) occurs : 

1.) having beakpoint inside save(...) method in action class shows it
hit the right method and is working.
2.) but after "return mapping.findForward("WF_PARAMETER_CHOOSE");" from
my action, struts complains with status 404 :

message Request[/parameter] does not contain handler parameter
named method

description The request sent by the client was syntactically
incorrect (Request[/parameter] does not contain handler parameter named
method).

3.)it worked before deciding to use transactional tokens with :

Subject: [OT] (Slightly OT) Accessing individual array elements (was Re:
 "multiple" problems)


Ah-HAH!  I was adding back in some other methods and broke it again, but
I
think I get it.

My "setter" method is called "public void setIds (String ids[])" -- when
I
created a method called "public void setIds(int i, String ids)" that
killed
it because BeanUtils.populate was calling the wrong setter method.

What is the "correct" convention for creating getter/setting methods for
accessing individual entries within an Array when you ALSO have
getter/setters that handle the array as a whole?  I thought I had it
right -- I thought you overloaded the array methods and stuck an index
in.

RE: seeking shortcut name of current FormBean inside every html:from

[Jörg Maurer]

Okay, thanks for clarifying this. As this is my first struts project and
also first time using jsp with a framework like this, I feel a little
uncomfortable about all this new tags.

However, now sure wanting to use JSTL, i just downloaded the jstl
reference impl from struts taglib group, where readme says following :
...
  CORE LIBRARY
EL:  <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
RT:  <%@ taglib prefix="c_rt" uri="http://java.sun.com/jstl/core_rt";
%>

Okay, now i read in
http://www.onjava.com/pub/a/onjava/2002/03/13/jsp.html?page=2
"In order to be able to support both the scripting (rtexprvalues) and
the expression language (elexprvalues) worlds, JSTL has the concept of
twin tag libraries: one that supports the expression language, and one
that supports request-time expression values. It's assumed that most
developers will use the EL-based tag libraries; however, it's still
possible for scripting page authors to use JSTL with rtexprvalues. Using
the rtexprvalues will provide the benefit of type safety and performance
via the request-time based tag libraries (their URI simply has the -rt
suffix appended)."

Question is : If i use the RT library as i want to expose it as
scripting variable, I learned that i still have to use  or
struts  to expose a scripting variable, right ? - no
support for that in JSTL cause  is deprecated ?!

But scoping to my original problem, i think you solution

will serve my aim quite right.

actually, scratch what i just said about not needing the bean:define
tag,
you would need it because the html:form tag will not make the form
available
as a scripting variable.  That's why I'd use the EL, since it will not
need
to create a scripting variable.

RE: seeking shortcut name of current FormBean inside every html:from

[Jörg Maurer]

Hi John, thanks for answering - you might be right on the issue I should
use a EL tag instead of scriplet.

What i am basically interested in : When processing a jsp using a
html:form tag, i guess html:form brings the current form bean object
into some scope accessible to my jsp - but under what name does that tag
expose it?

My form bean is defined in struts config as 




Cause when used (please forgive my ignorance on your EL solution for
now): <% if (ParameterForm.getStructure_changeable().intValue() == 1) {
%> so.. uuus ... the jsp compiler always asked for a static method
on ParameterForm. uuus , because I suddenly think that naming the
variable like the class of form bean( the name after it is exposed
later), is an most unlucky coincident, isn't it?!?!!? -> if is, then i
should rename the bean name in the struts config.

Anyway, is the exposed from bean cast to the correct type for usage :
- inside EL-Tag you wrote it is correctly typed 
- but for scriplet, isn't it just exposed as being of type
java.lang.Object ?!?!

Since this post i have been using massively e.g. 
in my jsp´s to grab the reference to the current FormBean like e.g.


...

<% if (parameterForm.getStructure_changeable().intValue() == 1)
{ %>


Please mail the applicable "shortcut" name (as i have forgotten the full
name, has'nt it been sth. like "org.apache.struts") and in which
class those constants are denoted. Addendum : Once i got that reference,
do i have to cast that reference to the correct form type - like : <% if

WOW for struts reflection using multibox + pls assist with usage of nested taglib

[Jörg Maurer]

I can't believe it - it works! Look at this : I am currently
(?overengineering) organising my view data in the following way :

TicketTypeForm
| _ property type Vector of  "tickettypeChooseViews"
|...|_ each has 1. property type
vector of "multiBox_ids"
  2. property type Array of
"selectedMultiBox_ids"  


Okay? So now populating them in jsp via :



...and later..
 

   ...and later ..
 

finally...
 
 



 




-> and WOW - they found properly forth and even back. Of course I did
all my reset(mapping, request), beginning from TicketTypeForm's reset
delegating to the reset method of my tickettypeChooseViews.

By the way, my first mistake was, that i used the exposed id TTForm to
populate directly via 

 
 


...so they found the way bean -> jsp but were not populated the way html
-> bean. As my learning, for such nested data structures on the way back
always begin at the root.

?!?!? By the way, can anybody assist me in rebuilding this example
properly with "struts nested taglib" - suddenly I think i do some double
work, isn´t it ?

Just as I thought myself a possible solution for that, why not use

Well, I'm ready to blame the driver.

I'll spend some quality time on this in the morning so that the 
ResultSet don't have to be returned before closing the other components.

I'm actually getting ready to merge some of this with Commons SQL, so 
that there aren't two overlapping packages.

4.  Started Tomcat so that struts-upload is deployed.
5.  From Mozilla, accessed "http://localhost:8080/struts-upload";.  
6.  The file upload screen displays properly and if I browse to a

error.  However, if I leave the file name empty or enter an invalid file
name, then I get the error shown below:

Others on this list have apparently had success with empty file names.
So I am very confused as to why I still see the "populate" error.  I
have tried Struts 1.1B2 and Struts 1.1B3 and JDK 1.4.1 as well as 1.3.1

What happens if the user does not specify a file to upload and you 
submit the form?  Do you get an error?  How do you handle this?

RE: Extending the RequestProcessor class

[Jörg Maurer]

Don't want to be that a wacky answer, but I read the source - only free
hotspot for myself newby-level seemed to be (quoting
org.apache.struts.action.RequestProcessor):

/**
 * General-purpose preprocessing hook that can be overridden as
required
 * by subclasses.  Return true if you want standard
processing
 * to continue, or false if the response has already
been

 */
protected boolean processPreprocess(HttpServletRequest request,
HttpServletResponse response) {

return (true);

}

...where myself subclassing had put sth like sample from book
"Programming Struts" :

  protected boolean processPreprocess( HttpServletRequest request,
  HttpServletResponse response){

HttpSession userSession = request.getSession(false);
// Check to see if there's a session for the user that wasn't just
created (or if he didn´t logged out - ? does session invalidate on his
browser as well ?)
UserContainer uc =
(UserContainer)userSession.getAttribute(IAppConstants.USER_CONTAINER_KEY
);
if ( uc == null || userSession == null || userSession.isNew()){
  //continueProcessing = false;
  try{
userSession.invalidate();
userSession = request.getSession(true); 
ApplicationContainer ac =
(ApplicationContainer)userSession.getServletContext().getAttribute(IAppC
onstants.APPLICATION_CONTAINER_KEY);
userSession.setAttribute(IAppConstants.USER_CONTAINER_KEY, new
UserContainer(ac));
response.sendRedirect( "/index.jsp" );
return false;

org.apache.commons.scaffold.text.ConvertUtil.addParam now and then

[Jörg Maurer]

I experienced that buidling AF and adding Parameters via
ConvertUtils.addParam(af.getPath(),"method", "choose") from Husted´s
Commons Toolbox  adds URL rewriting to params, so that & -> & . On
forwarding even via redirect, & was never resolved correctly (?
cause of html:base used in jsp ?). I resolved it via writing my
query-Path literally (?name=1&method=2&...).

My question : What is correct usage of ConvertUtils.addParam ? Not
delivered with struts dist, what is the correct equivalent for adding
params to request transparently?

Subject: html:multibox and arrays in the ActionForm


I have been using the most excellent ``Struts in Action'' by Ted Husted 
et. al., but I need a little clarification.

There is a code snippet from an ActionForm:

private String[] selectedItems = {};
private String[] items = {"UPS","FedEx","Airborne"};
public String[] getSelectedItems(){
return this.selectedItems;
}
public void setSelectedItems(String[] selectedItems){
this.selectedItems = selectedItems;
}

The JSP code snippet is this:








The html code in my case was produced by DreamWeaver and the checkboxes 
must go in table cells which are of irregular size, so I cannot just 
iterate over the items array. Do I need the selectedItems and items 
arrays? What's an alternate way of addressing the items array if I don't

use the logic:iterate tag that will still be palatable to Struts if not 
a ``best practice.'' If I don't use the JSP code above, will the proper 
array be populated by Struts?

BTW, I'm using Struts 1.02 on Tomcat 4.1.18. The people I'm working with

are not ready to move to a Struts 1.1 beta.

RE: nesting tiles with definitions in xml

Jorg>> This way each of the tiles is an independent entity.  Which has
it's
downside - but in a portal situation a single action cannot manage all
the
potential data required for a specific user.  Using tiles actions on a
per
tiles basis you can separate each of the controller/business logic - if
the
tile is required then the appropriate tiles action fires - if not then
no
extra work is done.  It would be difficult in the tiles definition or
template to define every possible combination in a portal layout.
Especially if the user is allowed to move the tiles around.

Having to write some breadcrumb code I bumped into your situation where
I
wanted the parent definition visible to a lower level tile.  By using a
tiles action I was able to determine the definition being used in the
template at run time and load a request scope bean so all the tiles
could
have access to the definition data.

The component context is only exposed to the definition not to nested
definitions in subsequent jsps.  You can pass them to nested jsps by
pulling
them out of the component context in the jsp - then adding them to the
page
context - using a list or bean.  Once in the page context the
subordinate
jsps can get to the data by including the list/bean in the subordinate
tiles
insert.  In the tiles documentation there is a portal example using this
technique.

1.) If i defined in defintion.xml sth. that should work in jsp code like
:

base.layout ->  base_layout.jsp ->  
  ->
workflow_content.jsp

  ->  register_region.jsp

this always gives me null exception. Why? Am i missing some
 or   ?

2.)I do a workflow in 3 steps with tile/tile definitions , called from
struts actions. "register_region" is the tab in the North, content in
south.








  





















I wondered why i have to define all tiles in base.layout abstract(via
" " ), just to override them in inheriting tiles with concret
*.jsp. So it is not an extending relationsship, only overriding
possible?

Hi again. Thank you for the information/citing - very interesting and
something I will investigate further.

Maybe I am overlooking something here but I assume my problem at the
moment is I will never get to my Action to check any token after the
User submits the form.
This is because the actual population of the form bean fails as the
new Session's form bean instance does not match what is on the page.
I suppose I need some sort of check on the page before the form is
submitted and the form bean population occurs.

Or I am totally going about this the wrong way ?

thanks once again.

I will see...

CITING BEGIN
"
Using transactional tokens
Duplicate submissions can often be a problem for web applications.
Struts supports
a strategy to prevent duplication submissions using a synchronizing
token.
Using synchronizing tokens is automatic for the Struts 
tag.
If it sees
that tokens are being used, it automatically includes the appropriate
hidden field.
On the Action side, you can enable transactional tokens by calling
saveToken(request);
anywhere in the Action's perform or execute method. On the return
trip,
to have
an Action check if a token is still good, call
boolean valid = isTokenValid(request);
If this method returns false, branch to an error page. If it returns
true, call

if you can use the TRANSACTION token that is activated in form +

you might be able to test for that -> if new instance of the form is

I cite now a passage of book from Mr. Husted et al., "Struts in action",
Manning, copyrighted .. I hope i not get into trouble, but help is
more valuable for me than strict law(despite i bought the book and not
going to sell following information).Am i disclaiming in correct
way?!?!?!

I will see...

CITING BEGIN
"
Using transactional tokens
Duplicate submissions can often be a problem for web applications.
Struts supports
a strategy to prevent duplication submissions using a synchronizing
token.
Using synchronizing tokens is automatic for the Struts  tag.
If it sees
that tokens are being used, it automatically includes the appropriate
hidden field.
On the Action side, you can enable transactional tokens by calling
saveToken(request);
anywhere in the Action's perform or execute method. On the return trip,
to have
an Action check if a token is still good, call
boolean valid = isTokenValid(request);
If this method returns false, branch to an error page. If it returns
true, call
resetToken(request);

Hi all

I have a form and Session-scope form bean class that consists of
amongst other fields, a variable length list of data. When the form
bean is created, the list is length zero and when data has been
retrieved and displayed from the backend, the list will contains the
corresponding elements.

The form works great until the User's Session times out and the User
still have the form visible in the browser. When the User submits the
form, the original form is gone so a new instance of the form is
created (I assume) but the population of the form fails as the number
of elements in the list does not match what is currently on the form
being submitted.

The Users always end up sending an error page. Any suggestions please
to solve my messy problem ?

thanks very much
Aisling

Yo!

How is policy/law in that and other use groups - I want to copy a
passage from e.g. Husted´s "Struts in action" to reply/or ask to a
struts user. 

Am i breaking some laws/interests with that? Is there a formal note i
have to include when posting. Is it relative to amount of posting -
number of lines e.g.?

Which law does apply - of my country, the server/company hosting it or
international law?

Asunto: ? on logic:empty - any hints

Hi!

I want to test in jsp if user does need to log in, e.g. if user has
already logged in and by back button is calling login.jsp for second
time.

My login.jsp has code :











You are already logged in!



So i test for that bean named UserContainer in session scope, where it
resides when login completes.

Unfortunatly, if user not logged - it throws
"[ServletException in:/login.jsp] Cannot find bean UserContainer in
scope session'"

Reading api docu, I thought logic:empty would test bean for
null(existing or not existing)?

Can any of you help me ?

Subject: Obtaining valid ModuleConfig.



Hi,

I'm using the following snippet in taglib code but it fails as 
config==null.  (Stuts 1.1 b3)

 public int doEndTag() throws JspException {

ModuleConfig config = (ModuleConfig)
pageContext.getRequest()
.getAttribute(org.apache.struts.Globals.MODULE_KEY);
if (config == null) {
System.out.println("config  == null");
}
if (config.getPrefix() == null) {
System.out.println("config.getPrefix() == null");
}
try {
pageContext.forward(config.getPrefix() + page);
} catch (Exception e) {
throw new JspException(e.toString());
  }
  return (SKIP_PAGE);
}

The code is based on the example that comes with struts.  I presume I'm 
missing something obvious but I'm new to Struts and can't track it down.
Could someone give me some pointers before I tear all my hair out ;-)

? Interference PLUG-IN(Tiles) versus CONTROLLER(Costum type)

[Jörg Maurer]

I just added my own Request Processor element to my app in
struts-config, which extended the ...struts...RequestProcessor and
defined a Plugin element for org.apache.struts.tiles.TilesPlugin.
On startup of app, the log gave me hint that TilesRequestProcessor does
not work with my costum RequestProcessor. 

So my question is, why do they interfere - different struts-config
elements for different functionality - as ican view it.

On subclassing my RequestProcessor from TilesRequestProcessor,
everything run fine.

Don´t now what to learn from this? Any hints appreciated.

You can write yours in a similar way.

to pass to action the CorsoSId(the user's select course from jsp) and
the 
IDFacolta.I tryed to pas an HashMap:
 
HashMap mappaOld=(HashMap)request.getAttribute("mappa");
/*the Attribute mappa contains now only IDFacolta and the next HashMap

RE: application resource/ prop messages of org.apache.struts.util.PropertyMessageResource NEVER GET FILLED WITH DATA ?!?!?!

[Jörg Maurer]

Problem solved - was following :

NETBEANS IDE has properties dialog (use OPEN) for any *.properties,
which displays a tabulated view of the texts. Okay. But on saving these,
some not ANSI characters are inserted in these. On deleteing these,
 e.g. displayed them correctly.

The open question : 
1)Why does the digester parse method inside Action servlet not throw
exception in struts 1.1 beta 3 and continues to instantiate a
PropertyMessageResource, while struts 1.1 latest build(20030128) does
throw exception(even not logging what the exact failure might be)?

2)What about non ANSI message resource textes - do they work with
UNICODE?
