ActionError Header/Foorters - can Global vs Non-Global be differentiated

[Greg Callaghan]

Hi,

Noting that one may use an ActionError, and struts ErrorTag to display both 
GLOBAL and validation errors (non-GLOBAL).

Currently the header/footer text I use is focused on the non-Global errors 
(ie validation errors in a form).  Is there a way with struts to throw the 
errors back such that it would be more like the following -:

* Global Error1 (eg for resource not available error)
* Global Error1

 eg correct validation errors in form before proceeding
* Validation Error 1 - date should be in dd/mm/ format
* Validation Error 2


Regards
Greg

For some reason the validator framework is no longer generating errors.
I am running three tomcat web applications. Each has it's own
validations. When they load up I can see the validations in the output,
but when I hit the page it says "no errors detected" and moves on?

Does anyone have any ideas on what I could be doing wrong? Excerpts from
my setup are below. Thanks in advance for any help...

Connections & Transactions

[aneesha . singh]

Hi all,

I have a question. If I have a DAO that is implemented as a simple java
class. I make a connection object at my session bean and pass it to the DAO
object. And the DAO object does all its operations on that connection
object. Then will the DAO come into the same transaction scope as the
session bean

This is really urgent. Would appreciate any help,

Thanks
Aneesha

I'm pretty sure the database is always queried.
If you have debug on you can see the calls.
This is important if you want to dynamically
change the roles.

Re: Struts vs. WebLogic 6.x

[Alex Lin]

Hi,

We have send one person to Vic's Dallas training.  She had the same
issue as i was in Bravepoint training.  Both trainigs use Struts 1.1
and deploy to Tomcat.  Everything on TomCat work fine.

However, after i deploy the project into WebLogic, project broke.
Initially, i guess the problem is probably on the limitation that WebLogic
can't identity jsp under WEB-INF.  Now, i'm not sure.  My collegue
received the same problem as mine during another Struts training.

Could you provide me a small example that use Struts 1.1 on WebLogic
6.x.

Thanks,
Alex

Struts Example App Mail Reader's Subscription Form

[iT meDic]

Hello Fellow Developers,

I have been stuck on this problem for a week and half now, i thought i could 
solve it without troubling you folks, however i need your help to clarify a 
few ideas and to get it working properly.

I have a multi-page form and within the form there is an mailing address 
form(with typical , street_name, city, country,etc fields). I would like to 
utilize the same functionality as the struts example Mail Reader 
Application's subscription Form (i.e. Add, Delete, Edit). However in my 
application there is no user logged into the session. But i am using session 
to span through 7 screens.

My question is how can i incorporate the subscription(example) form into my 
form without using the user_key. Is it possible to write the information the 
user enters into a session(rather than the xml file), and then allow the 
user to edit/delete that particular information?

I have tried to take out all references to the user constants but i get 
compilation erros. I am a newbie and will be grateful if you could provide 
me with a good place to start or modify the following code and point out 
what i would need to do to achieve the above.

Re: Help-Loading 2nd FormBean in same action???Is there an easy way??

[Greg Callaghan]

Hi Sandeep/all,

The issue is the ACTION parameter is already set on entry to the action (eg 
edit), but in the error case condition needs to be set by the action back to 
a different parameter (eg search) before forwarding to the previous search 
results page action.  Again because I'm using a common form bean to store 
the object search parameters (eg search_title) as well normal parameters (eg 
title), as a basis to trickle the search parameters through the chain so 
that after a object is modified the user can be thrown back to the 
"narrowed" list of objects on the search page based on the trickled through 
search parameters.

I guess its more difficult than I thought explaining this than I though, so 
perhaps it better I draw the line here.   Thanks for the input to date 
everyone.

The learning I think for me is that whilst it is good to reuse formbeans 
where one can, this should be only in cases where the validation 
requirements are the same.

I'm going to head back to a 2 form bean approach (object_search_formbean, 
and object_formbean).  In terms of trickling through the 
object_search_formbean parameters throught the edit/add/delete 
screens/actions I'll just drop back from struts to base JSP tags, ie




" >
" >
...etc for each object_search_form parameter

Greg

I may still be out of line here

That is what the "parameter" is for.  So you forward
to the correct action -- like "Search" and since the
action is common across search/add/edit/delete you do
a mapping.getParameter() to see which one it is.  The
advantage of having in the in the struts-config.xml is
that you don't have to set/reset.

am i still mising something?

Struts Design Help

[Bauer, John]

I have a somewhat complicated form to develop, and I would like to see if
there are some decent ways to implement with Struts.  The basic premise is
as follows:

1) Dynamic data on form, number of entries not known ahead of time
2) There are one or more Event objects that specify events that a user can
subscribe to.  An event has an event ID
3) For each Event, there are one or more parameters that need to be
specified by the user (i.e. monetary limits, etc).  A parameter has a
parameter id (global across events)

The basic form layout is as follows:

Event A description
Param 1 for Event A (textfield)
Param 2 for Event A (textfield)

Event B description
Param 1 for Event B (textfield)
Param 2 for Event B (textfield)

I am looking for ideas on how to structure the Form bean and use the html
tags for this situation.  I was looking into using the "indexed" property of
the html:text tag for the parameters, but it does not seem to work out in
this case.

Any suggestions would be helpful.

Thanks.
John

RE: Indexed tags & iterate tag problems

Anyone know the answer to this???  It seems that there are two of us with
exactly the same problem (see "iterate tag problems (sorry !!)" from Eddie
Fung [[EMAIL PROTECTED]]).

Bottom line: When using indexed tags inside an iterate tag, the setters
don't seem to be setting the new values.

If this has already been answered elsewhere, please just point us in the
right direction. :)

Hi All!

I apologize if this question has been asked before.  I'm trying to implement
indexed tags and I can't figure out where the values are being set (ie -
where should me setters be and what should they look like).  The form
displays the prompts and values perfectly, but when I submit it the new
values don't seem to be posting to the formbean.  I've read as many posts
and archives as I could find, but still don't see what I'm doing wrong.  One
archived post stated "... this will be translated by struts into a call
ParametersForm.getParameter(0).setValue(value) ...".  The setValue method in
EmploymentInfoField (see below) is not being called, though.  No errors are
being generated either (when I submit the form).  The HTML source that is
produced looks like this:

You make an Action error with "error.detail" but your messages file has
"errors.detail"?

RE: Seeking Know-How Advice: How Do I Implement Pop-up Error Windows With Struts

[Prengaman.Karen]

I wrote my own "errors" custom tag that sends back the javascript to display
the error in a popup window rather than the html sent back by the struts
error tag.  It still uses the ActionErrors that the struts error tag uses,
so none of your other code has to change.

Tough to do - the only solution (work around) I can think of is to have your
error page pop up a new window using javascript - but no real way to tell
the
backend "when you throw an exception, open a new window and display an
error". 
You can only tell the backend to "go to this error page when you throw an
exception".

RE: mapping.getInput() and request scope beans

[Prengaman.Karen]

Thanks for your help, everyone.  

Since I initially set (and compute) the needed request attribute in the
action that first loads the jsp, I specified the action mapping for the
input parameter instead of the actual jsp.  Problem solved!

Thanks again,

I have had a similar problem using the html:selection tag which is at first

is to do a request.setAttribute("bean",bean) and have a hidden field in the

Assunto: Re: EJB integrations


My approach has been to limit Struts' knowledge of the app's implementation
details ie EJBs. Thus I use struts actions to hide the HTTP based gui
implementation from the app. Struts actions convert HttpRequest etc into
application centric command objects thus the app knows nothing about HTTP.
My struts actions call methods on an interface which uses the facade
pattern. Hence all the app's functions are encapsulated in this facade.
Hence I can create different facade implementations ie one based on EJB, one
based on DAO and these can be dynamically configured at runtime...

Hence Struts knows nothing of the backend (EJB,DAO etc) and the backend
knows nothing about the frontend!

regards

Rob

I had the same problem.
When my condition to send back to the calling page is met I:

//Instantiate a new form bean
Form form =  new Form();

//here I set some of the form properties
//form.setIdField("1234");

//set the mapping attribute to the name of my form in struts-config.xml
mapping.setAttribute("exampleForm");

//then put your newly instantiated form in the request
request.setAttribute(mapping.getAttribute(), form );

When control is returned to the calling page, the new form will be in the request.


Hope this helps,

Hello,

I have a jsp that displays data and has a very simple one-button form with
one hidden field.  When this form is submitted, ExitAction is called.  In
ExitAction's perform method, if a certain condition occurs, I want to return
to the calling page.  I do this with the following code:

return new ActionForward(mapping.getInput());

My problem is that my jsp references a request-scope bean, and when
returning to it, the bean is out of scope.  If I put the bean in the session
the problem does not occur (i.e., the jsp can access it), but I would rather
leave the bean in the request.

Any thoughts on how I can get around this?  Do I have to specify a jsp file
in the input parameter in struts-config, or can I specify an action?

Thanks,

Karen

"Split Thread" with 2 Browsers

[John Regan]

This is not a pure struts question but i am hoping the framework might help
with this issue.

Desired functionality:
User opens browser, clicks through several pages as a certain "user type"
then opens a second browser because they want to be a different "user type".
The user should be able to proceed in either browser without session
information being overwritten in the other browser's session.  

Has anyone implemented any similar functionality?

Note: using tomcat 4.x as http server and JSP container.

Problem with Index

[Strichartz, Beth]

In an iterate,
if I do this 

<%=Index%>

the index prints out to the screen for me.


But, how do I do this??

<% if (String.valueOf(Index)) > 0) {%>

<% } %>
To check the value of the index??
Thanks,
Beth.

Re: Templates

[Cedric Dumoulin]

  You can't specify an action as template attribute. This is because action do a
forward, and jsp forbid forward once you have already written something in
response.
  Try to use Tiles instead (with appropriate tiles servlet). It should work.

Hello,

After testing the struts nighty build (beyond v1.0), i have found problems
of Struts on WebLogic 6.x.

1. The nightly build, including the common*.jar, seems mess up
   the weblogic.  I have deployed several bravepoint solutions onto
   weblogic 6.0 sp1, sp2, 6.1 still with MANY strange results.

   The solutions work fine on Tomcat 4.0

2. I had replaced several previous working struts projects with
   the latest build.  Problem happened again.

Both are confirmed after working together with another developer.

Do you have similar problem work Struts (nightly build) with WebLogic ?
Could i have a small example from you.

I think the problem with Weblogic is the JAXP. I had a similar issue when I

Hi,

The following reference is great.  After following the procedure below, and
deploy
the application into Tomcat, it works great.
http://www1.tramsasp.com/?section=dev&page=jb5Struts11.html&PHPSESSID=a015bb

However, if i deploy the same WAR (or directory) into WebLogic 6.x, it
doesn't work.
War file in web container is supposed to be universal, at least between
Tomcat
and WebLogic.  I couldn't figure out why.  Do you have the similar
experience on using
Struts 1.1 with WebLogic 6 ?

RE: Re-using JavaBeans as ActionForm Beans

Hey Stephen,

If I used containment, would Struts still be able to populate the set /

Thanks!

Subject: RE: Re-using JavaBeans as ActionForm Beans


Bill, 

The easiest way to reuse these is through containment. Just put an
instance of your bean as an instance variable of the actionFormBean and
expose get/set methods from the actionForm to give access to the
instance var. 

So, all you'd need would be two methods on your actionForm:
MyBean getModelRequest();
void setModelRequest( MyBean bean );

which get/set the underlying instance var: 
MyBean _GoodName = new MyBean();

you should make sure you don't return null from the get method. Then you
can use dot notation in your jsp files to reference the properties of
the contained bean, like so:



You likely won't need to use the setModelRequest method unless one of
your action classes wants to prepopulate the form with an existing
instance.

Hope this helps,

I have some beans that represent parts of my application (duh).  For

I want to re-use this bean (or object) as part of an actionform bean.

I get a little weak with some of the OO stuff in Java and this is where 
I run into problems.

I would like create an ActionForm Bean that uses the original bean and 
adds on the verify method.  This would let me keep the original bean for

other uses and even use it in other ActionForms.  I remember reading how

to do it somewhere but I cannot find it again.

I cannot extend the original because the ActionForm bean needs to extend

the ActionForm class.  

If someone can point me in the right direction I can do the rest of the 
research and tinkering myself...

Re: Re-using JavaBeans as ActionForm Beans (Clarification)

[Ted Husted]

This really only works if all your properties are Strings or booleans.
Binary types can't be transmitted by HTTP, and so can't be represented
to the user for correction. The ActionForm is a *buffer* to be used by
the HTML tags. Once the data is validated, it can be converted and
transferred to your application's JavaBeans. 

We tried making the ActionForm an interface in the first place, but, in
practice, there were simply too many side effects. 

http://www.mail-archive.com/struts-dev%40jakarta.apache.org/msg03590.html

http://www.mail-archive.com/struts-user@jakarta.apache.org/msg08070.html

If your JavaBean only uses String and boolean properties, and doesn't
make immediate state changes to your model, you can nest it and use the
dotted syntax. Otherwise, it's a wild goose chase.

Re: URL rewriting and cookies

[Ted Husted]

The img tag is mainly there in case the images in a secure location, and
the user needs to be logged in to get them. In which case, URL rewriting
would be required to retrieve them (or the user would be asked to log in
to retrieve each image ;-(

You are not required to use the img tag if the images are in a public
location. If the images are on another server, you may want to pass the
URL in a bean, or as part of your own tag. If not, you can also use the
conventional http://www.husted.com/struts/

Hello,

mixing your ActionForms with your business objects is not optimal. You 
will
lose the ability to use more "business-related  types" such as
java.util.Date (ActionForms mainly allow String only) - and also somehow
break the layered architecture (separation vs business processing).

Subject: Re-using JavaBeans as ActionForm Beans



I have some beans that represent parts of my application (duh).  For
example I have a bean that represents all of the information for a given
request.  It contains name, request, time, etc, etc... to

I want to re-use this bean (or object) as part of an actionform bean.

I get a little weak with some of the OO stuff in Java and this is where
I run into problems.

I would like create an ActionForm Bean that uses the original bean and
adds on the verify method.  This would let me keep the original bean for
other uses and even use it in other ActionForms.  I remember reading how
to do it somewhere but I cannot find it again.

I cannot extend the original because the ActionForm bean needs to extend
the ActionForm class.

If someone can point me in the right direction I can do the rest of the
research and tinkering myself...

Thanks much

Re: Error tag problem

[Sean Owen]

I believe your web.xml needs to be more like this:

  
   application
   com.myapp.web.ApplicationResources
 

The ApplicationResources.properties should end up in the same directory as
the compiled .class files for com.myapp.web. I suggest you copy it there in
your build process. Anyhow this setup works for me.

First visit to a form

[Dave J Dandeneau]

When using the validator framework is it best to visit the action on the
first visit or to send the user to a jsp which submits to an action
which then goes back the the jsp if there are errors? The other option
would be to sent them directly to the jsp on the first attempt.

Exactly. Forward them to a JSP page that looks like:

Re: Could not locate TLD META-INF/taglib.tld

[Andy Noble]

Hi Daniel,

I had this problem also, but only when using Forte v3 . I found my solution,
but it obviously won't work if you're not using forte.
I kept my TLDs in /WEB-INF/lib/tlds. The Forte application doesn't seem to
load all the subdirectories in to memory when the project is first opened.
So I had to manually open the TLD directory in Forte before I could
successfully compile/launch it.

I know it's unlikely to be this in your case, but I thought I'd let you
know.

Regards
Andy

RE: Re-using JavaBeans as ActionForm Beans

[Sobkowski, Andrej]

Hello,

mixing your ActionForms with your business objects is not optimal. You will
lose the ability to use more "business-related  types" such as
java.util.Date (ActionForms mainly allow String only) - and also somehow
break the layered architecture (separation vs business processing).

Check out this past discussion thread:

You can make your existing bean extend ActionForm. This will give you access

Can't delete upload temporary file

[Daniel WAMARA]

I've ended up by making a upload module in Struts (thanks to those who 
helped) but now I got a problem with the temporary file struts-created : it 
seems that I can't delete it with the destroy() method.

I've try to create a Security manager to check if I had permission to delete 
the file but the result was that I had none.

try
{
scman.checkDelete(file.getFilePath());
}
catch (SecurityException sexc)
{
...
}

So I created a new Filepermission for being able to set a new permission of 
deletion over the file

try
{
scman.checkDelete(file.getFilePath());
}
catch (SecurityException sexc)
{
...
FilePermission filepermission = new FilePermission(file.getFilePath(), 
"delete");
try
{
...

but I still have that permission and making all the uploads I'm doing just 
for thest could lead to a huge quantity of files, so how could I get ride of 
that ?

RE: Re-using JavaBeans as ActionForm Beans (Clarification)

[wbchmura]

Yes, I can definately do that - no problem there.  The problem is that I 
want to keep the original bean intact so that I can extend (or whatever 
the proper term will be) it to be used on several forms.

For example - lets say I have the original bean that has name and id.

I want to make one action form that validates the name and id 
differently than the a seperate actionform.  This way there could be two 
different validations, but only one bean in the back to modify 
(hopefully) if I wanted to add some new properties...

Hope that makes more sense than my first post!

Thanks

Bill

RE: Re-using JavaBeans as ActionForm Beans

[Stephen Owens]

Bill, 

The easiest way to reuse these is through containment. Just put an
instance of your bean as an instance variable of the actionFormBean and
expose get/set methods from the actionForm to give access to the
instance var. 

So, all you'd need would be two methods on your actionForm:
MyBean getModelRequest();
void setModelRequest( MyBean bean );

which get/set the underlying instance var: 
MyBean _GoodName = new MyBean();

you should make sure you don't return null from the get method. Then you
can use dot notation in your jsp files to reference the properties of
the contained bean, like so:



You likely won't need to use the setModelRequest method unless one of
your action classes wants to prepopulate the form with an existing
instance.

Hope this helps,

Stephen Owens

RE: Smart login page

The easiest way to do this is to use form-based authentication.  With this
container-managed mechanism, you can declare your protected resources and the
roles that can access them in your web.xml file.  Very slick once you get it
working.

A tutorial can be found at

I am running three tomcat web applications. Each has it's own
validations. When they load up I can see the validations in the output,
but when I hit the page it says "no errors detected" and moves on?

Does anyone have any ideas on what I could be doing wrong? Excerpts from
my setup are below. Thanks in advance for any help...

Error tag problem

[Pete Serafin]

All,

I am having a similar problem to Binh
(
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg18646.html

).
I was wondering if anyone has a solution as to why I cannot get the
 tag to work. I did notice that Struts docs say:

"In order to use this tag successfully, you must have defined an
application scope MessageResources bean under the default attribute
name, with at least the following message keys: errors.header,
errors.footer "

Where is the MessageResources bean instantiated and what is the "default

name" mentioned?

The following is how my app is set up according to my web.xml,
ApplicationResources.properties, strtus-config.xml,  and my ActionForm
and jsp:
1) ApplicationResources.properties:

errors.header=
errors.footer=

2) web.xml
...
 
  application
  ApplicationResources

   ...

3)struts-config.xml


  
  


4) LoginForm.java
 
 public ActionErrors validate(ActionMapping
mapping,HttpServletRequest request) {

ActionErrors errors = new ActionErrors();
if ((userID == null) || (userID.length() < 1))
 errors.add("login",  new
ActionError("error.userID.required"));
 return errors;
}
   ...

5)  login.jsp
...
   <%@ taglib uri="/WEB-INF/taglibs/struts-html.tld" prefix="html" %>
...
   
   ...


Im not getting the errors tag to print anything to the page, but the
validation is returning it to the form properly.

RE: SAX / Struts problem SAXNotRecognizedException

[Esterkin, Alex]

Try putting JAXP 1.0.1 JARs before xerces.jar in your application classpath.
This is the most popular of the known workarounds. Another workaround is to
use an older version of Xerces which comes with the Xalan distribution.
Reportedly, this problem does not occur in WebSphere 4.0

Indexes

[White, George W.]

Hi everyone,

My program allows a user to check several of many checkboxes.
Struts Multibox seem like a good choice.
Is it necessary to formally declare 'indexes' when using iterate, multibox
and arrays.
If so, please let me know where and how they should be declared. 

Thanks,

Re: Help-Loading 2nd FormBean in same action???Is there an easy way??

[Sandeep Takhar]

I may still be out of line here

That is what the "parameter" is for.  So you forward
to the correct action -- like "Search" and since the
action is common across search/add/edit/delete you do
a mapping.getParameter() to see which one it is.  The
advantage of having in the in the struts-config.xml is
that you don't have to set/reset.

am i still mising something?

Hi,

I have a vector that holds charging objects. The object has properties such
as name and amount.
On a page, at the top I iterate through the charging objects and create a
summary table. The table shows all the charging objects in the charging
vector and outputs their name and amount.

At the bottom of the page I want to create a form that the user can use to
enter the name and amount details for another charging object, hit submit
and have a new charging object added to the vector. Can this be done?

Thanks a lot.

struts action multiplexing

[Peter Pilgrim]

I want to multiplex struts actions.  I have a typical central Struts Action
that responds to multiple HTML Submit Button and provided my
own mapping to the behaviour or business logic within the same action class.

How ever I want to forward to another struts action with its own action form.
Unfortunately I find that ActionServlet seems to populating the target action form
with the wrong parameters. I discovered this is because the bean populate
work with `request.getParameter(...)'. This is quite correct.  So my target 
multiplexing
is sometimes messed up because it is impossible to override the servlet
request parameter.

How can I get around this problem?

Can a request dispatcher accept servlet CGI parameters?

mapping.findForward( "handleThis?parameter=one¶meter=two" );

I dont think so at first, becausethe Servlet Spec says you pass
request attributes ie. `request.setAttribute(...)'.

The other way would be the locate the action yourself without using request dispatcher
mechanism and then call the action directly. Can this be done?

iterate tag problems (sorry !!)

[Eddie Fung]

I've looked through the archives regarding the iterate tag and have
followed all the suggestions on use of the  tag but still have a
problem getting the form data to be updated. Yes I do have a 
getParameter(int index)
method but I still can't get the data updated in the form.

I have:






 /

 /




Where myForm = my ActionForm class

   myObjectArray is an ArrayList of myObjectBean objects

I have the following defined in the myForm ActionForm:

private ArrayList myObjectArray;

public ArrayList getMyObjectArray()
{
 return myObjectArray ;
}

public void setMyObjectArray (ArrayList anArray)
{
 this.myObjectArray = anArray;
}

public myObjectBean getMyObject (int index)
{
 return (myObjectBean) getMyObjectArray.get(index);
}

The myObject class has public getters and setters for all fields.

I can render the page but if I change the beanSelected, postDay, postMth or 
postYear
fields the changes are not reflected in the Form.

BTW Dave Hay how does Struts match up the getMyObject method with the 
myObjectArray ??

TIA

Setting up form from the query string

[Scriven, Marcos]

Hi

Is it possible in struts to setup a form like so:

myForm.jsp?action=3

Where in the form you have a property called action? The only way I have
been able to do it is this:


"/>

Which seems to be a bit redundant, what with repeating the property name.
I've also tried the method given in the examples app, whereby I have an
action just to set up the form. This seems rather an overkill for a form I
simply want to populate with a copule of values. Even then I still have to
pass the values in the URL like so: setupMyForm?action=3, which then
forwards to the new form bean, which then reads the values out of the
populated bean.

There must be an easier way!

Thanks

RE: Smart login page

[Rajeev Singh]

Stefano,
You can always store the LastRequestedURL somewhere either in session or
some other application scope object or also in query string. After login
is done the user can be redirected/forwarded to this LastRequestedURL.
  For this there is a catch that you have to choose whether u create the
session only after login or after once the first request goes to
controller.
  Query string is a best possible idea as you don't have to create
session before login is done. This choice depends upon your
architecture.
  e.g. when a request for B is submitted from A, user is redirected to
login page in following,
   response.sendRedirect("./login.jsp?lastRequestedURL=B");

and when login is done create a request dispatcher object on request
parameter lastRequestedURL , then forward the request to this page.

Thanx,
Rajeev

You got it. That's exactly the scenario I want to realize.
BTW there was a typo in my message. Actually the question was:
"HOW can I realize this?"
Perhaps a solution could be passing the url of the requested page to the
logon page as a request attribute, so that the logon action would know
who
to forward to.
Anyway I'd like to know if there's a better/standard way to do this or
if
there's an example to refer to.

I want to put a radio button in a form and have the value of the "value" 
field to come from a bean, only I don't know how to do this.  The 
incorrect way to writting this is

"
/>

Which will give problems, how can I set the value of the "value" field 
to a value in a bean?

Cheers

Tony

Re: Missing message for key index.title - general comments

[Keith Bacon]

Frank,
I agree very much! Error messages that have a unique
cause & point you towards the solution are much better
than things like
'can't find x in scope null'.
It takes time to add this stuff to code. An
alternative is for us users to set up a faq list or a
common errors & suggested solutions database. I'm not
volunteering, I'm only an occasional struts user -
hoping to use it more though.

You got it. That's exactly the scenario I want to realize.
BTW there was a typo in my message. Actually the question was:
"HOW can I realize this?"
Perhaps a solution could be passing the url of the requested page to the
logon page as a request attribute, so that the logon action would know who
to forward to.
Anyway I'd like to know if there's a better/standard way to do this or if
there's an example to refer to.

What is wrong with property names ending in Date?

[Schauder, Jens]

Hi,
I try to present a date on a webpage using the bean:write tag inside an
iterate tag
like this:


  


it didn't work until I changed the property name in the jsp and the java
code to orderDat
I had the same problems with other properties ending in Date 

can anybody explain how this comes ... I'd submit it as a bug, but I can't
get through to the bug
database ... 


Below comes the error message I get:

RE: Smart login page

[Darryl Nortje]

I'm very new to Struts and the MVC design so if I get this wrong please
everyone let me know. Or rather let Stefano know how to do it. I'll get the
reply.

Stefano, the answetr to your question is 'Yes'. very vague but this is how I
see it working. 

You have two pages A, and B. Flow goes from A to B. Inbetween going from A
to B you have a check to see if user is still logged on, if he is not logged
on your controller servlet show the user the logon page, after success at
logon, the controller servlet knows that it must now show page B. Does this
make sense? Your logon page can be called from multiple parts within your
app.

I'm developing a web application with Struts and I'd like to realize the
following behavior.
When I load a page which requires the user to be logged in, I want to invoke
a login page and, after a successful logon, forward back to the page I had
requested.
I can I realize this?
