RE: struts-config.xml-Is there a tool to find errors in it?

[Jeff Martin]

What kind of error do you mean? Does it parse and validate against the provided DTD?

Hi

I have an error with my struts-config.xml file and I cannot find where 
the error is.  Is there a tool which will help me track down where the 
error is, the messages in the tomcat log files are not very helpful in 
tracking down the error.

Cheers

Tony

RE: Help with bean:write\bean:define whn property requires an argumen t

[Andras Balogh]

Hi,

I don't know if what you are trying to do can de done without a scriptet
code.
If you don't care about using scriptlet you could write something like:


<%=customerResults.banks(bankCode)%>

Best wishes,

Andras.

Re: Two Struts Research Questions...

[ejf]

let me take your second question first:
i used I18N tags on tomcat 1.3 they worked well and as i changed my 
languages preferances on my browese to test them, all worked well.
i then tried the same on orion - i spent about 6 hours trying to figure 
out why the page would appear without error but appeared blank - i had 
to seperate the I18N tags at least one space away from any other tag or 
figure!! wild little time waster...

as for your first question - one servlet can handle say a 'load' AND 
'save' function and direct the response back to whatever type of page 
you want visible and it can do it pretty well. use a command pattern to 
organize the presentation and you got it.
i don't know how it'd compare with struts though. (i have a meager 
example of such a command pattern around here some where - otherwise i'd 
sent it to you)

hope that helps

Help - new struts user questions

[Tony Ziolkowski]

I am planning to use struts in a Jetty environment and am just starting to
play with jetty. There's some things I don't understand. The installation
documentation refers to my 'web application'. Is that the jetty application?
If it is, the installation guide refers to copying files into the web
application WEB-INF/lib directory. The jetty installation doesn't have such
a directory.

I have just copied the .war files into a struts directory and modified the
demo.xml files as documented. How do I access the struts stuff contained in
those .war files?

Hi Antony,
Are you using Sun's JDK 1.4 beta.. I got the same 'object is not an 
instance of declaring class' - error when I used JDK 1.4.
Try switching to 1.3

Yes I am using 1.4beta.  But an almost identical webapp works with

Re: struts-config.xml-Is there a tool to find errors in it?

[Tuomo Syvänperä]

The problem only came up occasionally. If I had two webapps and I 
started the servlet container and accessed one of them, it works fine. 
If after that I try to access the other one, it gives the error below.
Everything has worked fine since I switched back to 1.3 JDK.

strutshtml select tag initial value

[Tom Watkins]

I have a jsp using the  tag with nested  tags. I
need to give the drop down list an initial value first time it is seen which
I have done using ...

However, when page validation fails I need the list to display the user
selected value but obviously it reverts to the  tag which I labelled
"selected".

I can see no obvious way of doing this (although I am sure there is one)

Can anyone help?

I changed to have tomcat run with 1.3 and it works fine now.

Question for someone. Is the active development of struts done with Suns 
JDK1.3 or Suns JDK1.4? or  some other vendors JDK.

Does it pose any problems developing an application with JDK1.4 and 
running it on

Tomcat4 using JRE1.3?

RE: Help - new struts user questions

[Jon.Ridgway]

Hi Tony,

Sounds like you may have to do a bit more reading. Just to get you started.
A web application is the code that you will write and deploy on jetty. I
have not used jetty so I can't give specifics. But somewhere under the jetty
install you will find a deployment directory. This is where you put the war
file.

A web application has will have a WEB-INF directory where configuration and
support files are placed. WEB-INF/lib contains any jar files used by the web
application. Try having a look at the structure of the struts-example.war.
This should clarify things a little.

Jon.

If it is, the installation guide refers to copying files into the web

a directory.

I have just copied the .war files into a struts directory and modified the

It looks like you may have a problem with your struts-config.xml file. Try

RE: Invalidate and container authentication in multi-app environment

[Jon.Ridgway]

Hi Michelle,

I think, but not sure, that this is one of those things not covered by the
JSP/Servlet spec. IBM I know offers bespoke single signon support. I suspect
that WebLogic will have something similar. It sounds like you may need
something like this; that's assuming that your application 'A' and 'B' are
running within the same environment.

Subject: Invalidate and container authentication in multi-app environment

Hi,

I have been researching the archives trying to resolve an issue.
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg10294.html
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg14538.html

These threads describe my situation pretty closely (although not exactly) 
and the solutions provided have not worked for me.

I will describe the problem here again and hope that someone out there may 
be able to offer advice.

I am attempting to implement a Logout action which will log out the user and

forward them back to the main page of the application.  The main page action

itself is secure and should prompt for authentication before allowing the 
page to be viewed.
In the logout action:
a) invalidate the session
b) forward to the application's main page (redirect=true)

Now, normally if I just log into this application (let's call it Application

A), do stuff, and then log out, the logout is successful and the login page 
appears as expected.

Now, here's the twist.  If I log into another application (let's call it 
Application B) and just change the url (without logging out) to point to 
Application A, log in and then try to log out of Application A, then it does

not log out.  It behaves as though the user was still authenticated.  If I 
log out of Application B before changing the url to point to Application A 
then I am able to log out successfully.

Let's review the scenarios.

Scenario A
- bring up new browser window
- log into 'Application A'
- do stuff in 'Application A'
- log out
- result:  logs out properly.

Scenario B
- bring up new browser window
- log into 'Application B'
- change url, without logging out of 'Application B', to 'Application A'
- log into 'Application A'
- do stuff in 'Application A'
- log out of 'Application A'
- result:  does not log out properly, it should prompt for authentication 
before showing main page, but does not.

Scenario C
- bring up new browser window
- log into 'Application B'
- log out of 'Application B'
- change url to 'Application A'
- log into 'Application A'
- do stuff (ie. go to add page)
- log out of 'Application A'
- result:  logs out properly.


I guess if the users were properly disciplined to log out of their 
application before moving on to another application then this would never be

a problem...but... the world is not so perfect.

Any ideas?  Has anyone encountered this before.

I am running Weblogic 5.1 sp10 using Struts 1.0 release.


Thanks,
Michelle

Subject: PLEASE COMMENTS! Design question on very long lists... (a little
bit OT)

Hi to all!

I strongly appreciate struts - it a very valuable tool to work with. So I
started to build a EIS-similar application with much DB-Access, business
code and so on... (try to work with Jonas EJB Server). But there arer some
design question and I do appreciate comments on these.
I have plenty of masks with DB-Access and CRUD-Operations. You can make a
choice based on the Primary Key (or something else). E.g. Articels have a
primary key, let's say WCF1001, REI1002, VAT-Code can be choosed, Zip-Code,
Customer Name and so on. On behalf of articels: I am using html:select and
build a selection list, but there are thousands of Primary Keys and you have
to send MANY bytes through the net building the mask (think of many
selection list in one mask!!).
What is in your opinion the "best" method the keep the selection lists
short? Can I resend/request the selection list, building new ones with the
next key? Is it possible to simulate the behavior of - let's say - of the
help index of Microsoft? Or is it convenient to build short lists with
beginning letters, then "climb down" to a next short list a.s.o??
Have I to switch to applets (with all its disadvantages...)? 

I am very eager to hear the opinion of you!

Thanks
Thomas

RE: Moving to Struts

[Jon.Ridgway]

Hi Aneesha,

To get you started, Struts has four main elements/concepts.

- action classes (you write these and put calls to business logic in them)

- form beans (again you write these and map them to a FORM. Struts uses the
form bean, populating it with values from the submitted form, before
forwarding it to the associated action class)

- Struts provides a number of tag libraries; html, template, logic and bean,
see http://jakarta.apache.org/struts/index.html.

- struts-config.xml (this config file associates your form beans with
specific actions and more...)

As to the work required, I guess it depends upon the size/complexity of your
app; Struts does help keep custom code to a minimum however.

Jon.

http://jakarta.apache.org/struts/struts-html.html#link


If you prefer to specify a java.util.Map that contains all of the
request parameters to be added to the hyperlink, use one of the
following techniques:


Specify only the name attribute - The named JSP bean (optionally scoped
by the value of the scope attribute) must identify a java.util.Map
containing the parameters.
Specify both name and property attributes - The specified property
getter method will be called on the bean identified by the name (and
optional scope) attributes, in order to return the java.util.Map
containing the parameters.
As the Map is processed, the keys are assumed to be the names of query
parameters to be appended to the hyperlink. The value associated with
each key must be either a String or a String array representing the
parameter value(s), or an object whose toString() method will be called.
If a String array is specified, more than one value for the same query
parameter name will be created.

Re: accessing EJB components from a Struts application?

[barry]

Vic,

You should not extend the form bean for Data access as
it is part of the View of MVC. The data Access should follow on of two
Patterns DAO which allows for EJB or
JDBC or the following:


To implement a screen of the particular Use Case, the following artifacts
should be created:

1.Action class handles logic of that particular screen, errors and,
probably, validation.

2.ActionForm class stores and validates the data presented on the
screen.

3.BusinessDelegate class is responsible for finding and performing
inter-tier method call of the Stateless Session EJB façade object that
resides on the business tier. The value objects facilitate the interaction
between BusinessDelegate and UseCase Façade. See the description of Business
Delegate pattern at
http://developer.java.sun.com/developer/restricted/patterns/BusinessDelegate
.html. See the description of ValueObject pattern at

4.Use Case Façade is Stateless Session EJB, which sits on the
business tier and implements system-wise business methods that perform the
logic of Use Case. See the Session Façade pattern at
http://developer.java.sun.com/developer/restricted/patterns/SessionFacade.ht

5.JSP Page represents view in the MVC pattern. It should contain
only HTML code and all the logic should be encapsulated into the Struts JSP
Tags.

And I think the only people using SOAP at still at SilverSteam.

Hi,

have you checked in the mailing-list-archives at:

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

Searching for "HashMap" resulted in a list containing a reference to
this message:

http://www.mail-archive.com/struts-user@jakarta.apache.org/msg19443.html

Which seems to do what you want...


hope this helps

If you prefer to specify a java.util.Map that contains all of the
request parameters to be added to the hyperlink, use one of the
following techniques:


Specify only the name attribute - The named JSP bean (optionally scoped
by the value of the scope attribute) must identify a java.util.Map
containing the parameters.
Specify both name and property attributes - The specified property
getter method will be called on the bean identified by the name (and
optional scope) attributes, in order to return the java.util.Map
containing the parameters.
As the Map is processed, the keys are assumed to be the names of query
parameters to be appended to the hyperlink. The value associated with
each key must be either a String or a String array representing the
parameter value(s), or an object whose toString() method will be called.
If a String array is specified, more than one value for the same query
parameter name will be created.

Hi,

I've read this in the struts examples that come with the source code.
<%
   java.util.HashMap newValues = new java.util.HashMap();
   newValues.put("para1", "value1");
   newValues.put("para2", bean1.getAttribute1();
   pageContext.setAttribute("paras", newValues);
%>

   


You put all your parameters in a hashmap an pass it to the
 tag.

I would prefer something like this:

AW: accessing EJB components from a Struts application?

[Stefan Frank]

Hi,

i'm not very fond of these Helper-Classes: Most of the time, they only add
an additional Layer which just proxies calls to the SessionBeans: The
benefit you get is mostly, that you can wrap all ejb-related errors inside
the Helpers. This saves you some coding, but most of the time you want to
react on a RemoteException in a different way the than on a finder
Exception.

We code the EJB-Access driectly in the Actions and try to keep the Actions
small by keeping most of the Code inside SessionBeans (which is a generally
a good idea, as you can reuse this code in context's where Struts is not
applicable, eg. with a Swing-Client). In order for this to work, it's a good
idea, to use a
SessionFacade(http://java.sun.com/blueprints/patterns/j2ee_patterns/session_
facade/index.html) to avoid having to code against numerous ejb's in your
action - in our experience, this is sufficient: A helper-class just doubles
the Methods of the Facade.

Check out, if portability from an ejb-Architecture to a pure-jdbc
Architecture is really a requirement, or if it even is possible: I'm not
really sure, wether it pays to code independently of the j2ee-architecture,
as it means to wrap most of the main-features (EntityBean, SessionBean, MDB,
jndi and so on) - with applicationspecific classes that abstract out the
functionality: I think in projects under high pressure you throw away all
the benefits of j2ee with this approach.

So, by keeping the code in the actions small, we us Actions in a
"Command"-way: which works quite nicely for us: As there is not so much code
in the action, we don't have problems with writing new ones or changing the
old ones.

hope this helps
greetings
stf

Re: strutshtml select tag initial value

[Keith Bacon]

If you use the struts option tag it will get the
selected value from the formbean when the page is
displayed (reverse of the way it sets the selected
value when the form is submitted).
Then you have full control!

Hi,

well the first phrase "I've read...code. <%... " gives exactly a working
code-snippet. I think using that it should be easy to get a working
version in your own code...

Re: servlet question

Hi William - just quick suggestions
1 - search for files called *.xml & look in them.
2 - or scan all files for "HttpServletRequest"
That ought to find them.
Just maybe the servlet spec specifies where this info
is stored?

Re: Forwarding from one action to another action

[Keith Bacon]

I Hope I have this right!
The form bean is lost, struts doesn't add it to the
request before running browse.jsp is run.

So - make "browse" map to /browse.do so browseAction
will be called & can get your object.

I see you are adding that object to the formbean - I
prefer to add things like this to the request - the
jsp can get them from either place. I just think it's
more straightfoward.
hope helps

jsp pages under WEB-INF..

[neil]

Hi, I know this question has been answered before, but I cannot find the
answer :(

I have placed all my jsp pages under a subdirectory of WEB-INF, as
recommended by Ted Husted. I would like a default page when I go to the
application (like an index.jsp), but I don't know how to do the mapping. I
assume I need to put an action mapping or global forward in
struts-config.xml and something in web.xml?

Any help would be greatly appreciated

Thanks

RE: jsp pages under WEB-INF..

[Park, David]

If I understand the philosophy behind placing JSP pages in WEB-INF, it
is to secure them as resources... Only JSP pages that are NOT to be
directly navigated to should go there. These JSP pages can be accessed
by being included from another JSP page, or forwarded to.
 
Welcome files, such as index.jsp should continue to reside in the top
level of your application.
 
Hope this helps,
-david

I have an error with my struts-config.xml file and I cannot find where

Hi

Why dont you amend the example from http://www.ecerami.com/xerces/ where the

The stack trace and warnings should be sufficient to figure out where the

Or you can put this into the web.xml file

  
logon.jsp
  
So this page will be loaded when you write only your context.

http://myserver/myContext/ will load hoooppp-> the page

Re: Personalized content using Struts. Jetspeed?

[Ted Husted]

Jetspeed is using its own application model, based on "portlets". 

These are basically web applications within web applications. 

I've looked closely at the model myself, and eventually came to the
conclusion that what is really needed is a good way to plug "modules"
into an existing web application. The portlet model allows this, but
everything ends up tied to the portlet API (which Jetspeed and Websphere
are inventing together). 

Personally, I believe given some modest personalization features, Struts
can provide the same features without resorting to creating another API,
which simply mirrors the web application API. 

Perhaps personalization should be viewed as an extension of the message
resources idea. Right now we have a (rather large) message file for each
locale. With personalization, the same concept applies, except that
there is a (small) resource file available for each user. 

Cedric has been doing some good work in Tiles regarding rendering a
portlet-like display. But for it all to come together, Struts needs to
support multiple configuration files and multiple controllers. You could
then plug one Struts application into another, the way Jetspeed lets you
plug in portlets. 

But, if you need a plug-and-play Enterprise Information Portal, and what
Jetspeed bundles meets your needs, definately go for it. 

Though, personally, I would be cautious when it came to actually
developing new portlets, since there is still a lot of unproven ground
there.

RE: jsp pages under WEB-INF..

[neil]

Right, first of all thanks for the replies to this question...
If my login.jsp lives under WEB-INF, can I still do this? I basically want
to auto load a welcome page that itself sits beneath WEB-INF. I think I saw
somewhere recently that you must create an action class and mapping in order
to be able to access files under WEB-INF? Sorry if this going over old
issues!

But the other won't.

For the standard welcom page, the container sends a redirect back to the
browser, and the browser then retrieves it. The browser can't retrieve
anything under WEB-INF by itself. 

The best all-around solution is to  put your own welcome page that
forwards to a Welcome action. This is a good idea regardless, since it
puts control into the Struts application. What your "welcome" action is
really should be part of the struts-config rather than the web.xml.

Re: AW: accessing EJB components from a Struts application?

[Chris Smith]

I like MVC as per : http://www.basebeans.com/struts.jsp (and just the 
summary part)

Here is Sun's approach, which I think just sells more hardware, from 
their web site:
"The key design pattern used in the Java Pet Store demo is the 
Model-View-Controller architecture, which separates three distinct forms 
of functionality within the application. To learn more about the 
Model-View-Controller architecture in the Java Pet Store demo, read 
Building Blocks of a J2EE Application from the previous release.
[Java[tm] Pet Store Demo]
JavaTM Pet Store Demo

New in Release 1.3
The Java Pet Store represents a typical e-commerce application, 
presenting views of products and services for sale, including cats, 
dogs, fish, exotic iguanas, and reptiles. The application incorporates 
the following technologies:
 * The JavaServer PagesTM (JSPTM) framework
 * Java Servlet APIs, including filters and listeners
 * The Java Message Service (JMS)
 * Enterprise JavaBeansTM (EJBTM) components, including 
container-managed persistence (CMP), message driven beans (MDB), and the 
EJB Query Language
 * Java Foundation Classes/Swing GUI (J.F.C./Swing) components for a 
rich client user interface launched via Java Web Start software
 * Java APIs for XML
 * Extensible Style Sheets for Transformation (XSLT)
 * Reusable web application framework

The application takes and processes orders, managing credit card 
information, user logins, shipping information, and shopping cart sessions.
"
Do you see how this is to complex? This is why I think people give up 
and go to Microsoft .NET. I would say a large majority of clients are 
moving to .NET.

KISS. (Keep it simple)
To me alternative is Struts as implementation of a MVC Frame work, which 
is a sweet spot, productively applied to a business application. (There 
are others who like coding just to get fun technology). To me EJBs were 
for distributed applications. I think less then 5% of applications out 
there need to be distributed, hence I ask a question why do you need an 
EJB? (Does anyone deploy client side Java?).

Or even this: http://java.sun.com/products/ejb/index.html
What is the business case?
Is it:
"Enterprise JavaBeans servers reduce the complexity of developing 
middleware by providing automatic support for middleware services such 
as transactions, security, database connectivity, and more.
". Is this true, based on your experience with developing EJB? CMP with 
transactions, this comes in handy? Should I only use it when I need 
middleware? What is middleware? I must need it.

I think we all make our choices for our applications and what I chose 
may not be correct for your application.

/* Flame: How can I change the business requirements spec for this 
application so I could use message driven beans? (if you do not get it, 
don't worry */

I would use Action as just an application controler.
Maybe you can just do a FormBean as just a bean and do a DAO by puting a 
  on it for DAO. (And if you go Swing use the same FormBean, Swing 
knows RowSet).

Vic
the FormBean dude.

RE: jsp pages under WEB-INF..

I see what you mean, but its a bit tricky to know where to draw the line
sometimes. A typical form which takes user input, may need to be navigated
directly, but at the same time there may be some grounds for wanting it
hidden under WEB-INF.

problem with bean:checkbox

[blaas]

Hi all,

I have a big problem with the bean:checkbox tag.

My form class (selectedForm) has two fields, one is a TravelPlan and the
other
is a Vector of  TraveAsset. Both, TravelPlan &  TraveAsset extend the
ActionForm
class as selectedForm do.
In TraveAsset I have a boolean field (selected) to manage from the jsp the
selection
of this asset.
In TravelPlan I have many boolen fields to manage the category of  TP
(family, cultural,
adventure )
The problem is when I use the selected form in my jsp, as I can't manage the
uncheck
of a category in the TravelPlan otherwise the unchecking of the selected
field in the list
of TravelAsset gets always caught by the action class.

my jsp is:




  

  

   Categories:
   


   family
   relax


   adventure
   culture


   summer
   winter

  

  
  

  


  
 Asset Name:
  
  
Selected
  

<%index ++;%>

  

  

  

   
  
   

  



could someone help me?

Re: jsp pages under WEB-INF..

[Ted Husted]

Orginally, it came up in the context of enforcing MVC and preventing
JSPs from linking to each other.  Another use would be to protected
selected JSPs. Though, once you start to discriminate, an actual
security scheme might be a better option.

RE: Can't build struts with jdk 1.4

[Drozdowski, Terry]

I hit a similar problem attempting to build the PostgreSQL JDBC driver with
JDK1.4.  Unfortunately, unless you want to stub out all the required methods
(not a short task), you'll need to also keep 1.3 around to build.  Runtime
with 1.4 and Struts works just fine.  Just make sure you (re)install 1.4
after you install 1.3 - keep you JAVA_HOME pointed at 1.3 when you need to
build and things should work out fine.

Subject: Can't build struts with jdk 1.4


Hi,

I'm trying to build struts 1.0.1rc1 and am getting a
build error caused by changes to java.sql.Connection
in jdk 1.4. Can the CVS version of struts work with
jdk 1.4? Or is there another way around this problem?
I really want to use jdk 1.4.

Using Swing Components as Visual Bean with struts

[Vimal]

Hi,
I am new with struts. I started to work with struts. For certain requirement I want to 
use the swing based Forms with struts. When embedding swing components as visual bean 
with JSP, it display the contents, but calling another Visual bean from current bean 
it throws the exception. Does struts does not supports the visual bean communication 
with each other. Can any one give the solutions.

RE: How to Forward from one action to another action

[MacKellar, Kimberly]

You need to add your object to the request or the session. 
Try adding 
if ("request".equals(mapping.getScope()))
 request.setAttribute(mapping.getAttribute(), oForm);
else
 session.setAttribute(mapping.getAttribute(), oForm);

Where your struts-config.xml contains something like

Hi All,

Here is the code which i've written in my action class.

 ABCustomerInfo[] oCustInfo = remote.searchAddressBookByCriteria
(iPartnerId,iBusinessId,data,true);
 System.out.println("Number of Customers "+oCustInfo.length);
 oForm.setCustomers(oCustInfo);
 ActionForward forward = mapping.findForward("browse");
 return (forward);

   Here it gets the data from the remote object. But when i go to the
forwarded browse file, i am getting customerinfo object as null. It says it
is not set. Can anyone help me to fix this?

Thanks and Regards

Programming Style, Custom Tags - Opinions?

[Bryan Field-Elliot]

Hi all,

I wanted to collect a few opinions on programming style with respect to
Struts and JSP.

The following have been my guiding principles for the last several
Struts projects I've done:

1. When a JSP page needs to ALTER the model (e.g. data will be written),
a Struts Action should be used.

2. When a JSP page needs to RENDER the model (e.g. read data, and
transform it into HTML), a JSP custom tag should be used to "get" the
data into a local (scriptable) variable/bean.

Over time, this strategy produces a roughly 1:1 ratio of Actions to
Custom Tags. Sometimes there's even a gray area concerning where to put
the logic -- e.g. if the very act of reading data will produce a log
entry, technically that's writing to the model -- however, I tend to put
"primarily read" operations into custom tags.

One reason why I do this, is so that the Actions don't necessarily have
to know every single kind of model data the resulting JSP page may want
to draw from. I leave it up to the JSP page to decide.

A drawback is that you end up with so much code in both camps -- it
would be nice if all the code could, for example, extend the same base
classes, or something.

I'd appreciate hearing some opinions on whether or not others have found
this style workable, and if not, then what works better.

Thanks,

Bryan

Hi,

I recently joined the mailing list and I am trying create a rule that will
move all email messages to a STRUTS folder when they arrive in my mailbox. I
am using Microsoft Outlook. I can't seem to get a rule that works for 
all messages. Any ideas would be greatly appreciated?

RE: Mail Filter

[Sobkowski, Andrej]

Hmm, not sure this is the place to ask this kind of questions...

Anyways, here you go. Define a rule saying that:
- when a message arrives...
- ... any messages coming from [EMAIL PROTECTED] should be
moved to a separate folder ...
- ... except the ones addresses directly to you or where you are explicitely
in the CC or TO (these may be personal Struts communications not addressed
to the list)

'works fine for me.

RE: Problem with bean:define? Issue with Date fields

[Siggelkow, Bill]

Well ... if you have been following this thread I thought I had a problem
with the 'define' tag ... actually my problem was not with the define tag.

The problem was I did not include a 'hidden' field to hold a date property
in my form bean.

Once I did this I was able to use the define as I originally intended.

It was a slight inconvenience to realize that I had to provide a special
'get/setDateAsString' type methods to hold the render/transform the date
value.

It would be nice if in the future, the Struts tags supported some automatic
conversion of Date objects.

Help with understanding validation and reset

[Siggelkow, Bill]

Okay, 
I do not think I understand the contract of the ActionForm validate
method.  The problem I am having is that I appear to
lose some a data value when I return to an input page after I return
validation errors.  Specifically, I have a Date property called 'postDate'
... the value of this property is displayed on the page (but NOT in a
form-field).  The date displays the first time I enter the page (after my
action that populates the form) but this property is blank (null) when I
return to the form (set as the 'input' attribute in the struts-config) to
display validation  errors.

BTW, I have set the form in the request scope in the Action mapping ...
should I be using a different scope?

Do I need to represent this date property as a hidden field on my form?  I
think that is my problem.

Ahhh - I grok!  The action servlet creates a new form when I press Submit --
this form does not have the postDate property set.

RE: AW: accessing EJB components from a Struts application?

[Cakalic, James]

If I had more time I would comment on this more fully as it seems some of
the ideas being expressed here are off-the-mark and short-sighted.

I don't mean to go on a rant here, but my job would be much easier if we
just used JSPs and JDBC. To heck with those creative types; if they can't
read our Java code then they shouldn't have a role in development. If they
want to change the look and feel of the application, let them just try to
work around my code. And why should I care about extensibility, flexibility,
maintainability, robustness, and scalability? I'm being measured on whether
I deliver the system by a specific date. Let the maintenance team figure out
that other stuff. I mean, don't they have the other 80% of the software's
life to do that? All I have is the first 20%! Model-View-Controller -- what
is up with that anyway? Aren't web applications just about displaying
something in a browser? If the user can't see it, it doesn't matter. All
that pattern garbage is just wasteful muttering. How often do application
requirements really change anyway? I think those guys at Prentice-Hall just
made it all up because they wanted to sell more books. All that stuff about
transactions and security. Isn't that why I buy a database? And why should I
let the people deploying the application make any decisions? They didn't
help me when implementing the application. Why should I care whether it is
easy to deploy and administer? Oh yeah, while I'm on the topic, this whole
open source thing is really worrisome. I mean, how can I trust that code?
And those licenses -- don't they say that I have to open up and give away
everything that I write if even one line of open source is in my
application? And why is that there seem to be multiple solutions to the same
problem? Jeez -- Jakarta even has two different regular expression
implementations. I wish one vendor would step in and give me just one way to
do everything on one hardware platform in one development environment with a
fixed set of services. Don't all good ideas come from one place anyway?
Excuse me, I've got some JSP/JDBC work to do -- or was that ASP/ODBC? See!
Now you got me all confused!

;-)

Jim Cakalic

RE: Problem with bean:define?

[Siggelkow, Bill]

Well, I did a test and bean:write displays the date the first time thru, but
then displays nothing when I return to the page to display validation
errors?  Why would this value be getting cleared in my form?  I null out all
my fields in the reset method including this 'postDate' property.  Any
ideas?

RE: Problem with bean:define?

[MacKellar, Kimberly]

This is happening because when you click submit and go to validate(...) in
your form class a new form is created and populated with the request
parameters from the JSP page.  So if you don't have postDate as a hidden
field or put the form in session the value will be lost.  Ted posted a
message on this topic not too long ago about how to handle this situation.

Hiding Struts Action Statements From Nav?

[Matt Koidin]

Is it possible to hide the Struts action statements from my navbar?

When I start my application I go to:

http://www.myapp.com/web/

Is it possible to have it stay with that root address and not change to:

http://www.myapp.com/web/action1.do
etc.

You could put your page in a frameset. Then the address bar would't change
when you navigated from page to page. Might cause other complications
though.

This is only possible if you use frames and "hide" one of them.  Quite a pain
to hide the URL - users never look at it much anyway.  Hackers might though...

JADE

[Sandeep Takhar]

there is an IBM UI Framework called JADE.  We are
currently evaluating it against Struts.  Has anyone
used it and done a comparison before?  Does anyone
have any comments about this UI Framework at all?

btw: there is a newer version of Jade which is 2.5 and
it is much closer to Struts now than in the past.

I still prefer Struts, but I want to be open to
everything and judge things fairly.

Re: servlet question

[William Shulman]

Thanks Keith-

I looked through all of the xml files (web.xml, server.xml, etc) as
well as looking through the DTD's. I did a grep for HttpServletRequest
and found nothing special. In conf/web.xml I did find a way to define
the default servlet but that is not what I am looking for. I looked at
the spec and found nothing. 

I did all this before I sent the original email and again after you
listed your suggestions. 

If you know the right xml file, could you tell me?

form beans bound to session

[Peter Wong]

Hi,

If a session scope action has an associated form bean, it will be
bound to http session once the action is invoked.
If a user does not navigate to a "natural exit point" so that it can
be explicitly removed in application code, there could be unnecessary
form beans in session.
Are there any strategies to deal with this?

Thanks.

Peter

Re: servlet question

[William Shulman]

Thanks Keith-

I did this before (and just did it again to be sure). None of the .xml
in files in my Tomcat dist (server.xml, web.xml, etc..) seem to
contain configuration of these elements. I do see where you can
specify 'servlet-name' in web.xml to define the Servlet class, but
this is not what I am looking for. I also looked at the dtd
definitions to see if they mention tags where I can define the 
HttpServletRequest and/or Session class -- no luck there either. 

I also did a "find . | xargs grep HttpServletRequest" and did not find
anything useful.

if you know which xml file allows for the configuration of these
classes, would you tell me?

Request Attribut and forward ??

[tw . richter]

Hello,

and thanks TWIC for the comments on large selection lists (by the way: where is the 
pager taglib?).

For the html:select and html:option I am using beans as describes in the 
struts-example. I've got a mask and a Form Action where I build the selection list. In 
the Action class I use a session.setAttribute("selectbean",list) and forward to the 
same mask. 
So far it works fine, BUT: I have a bad feeling to use session variables (because of 
the potential junk of memory..), so I want to use request variables with 
request.setAttribute("selectbean",list). But this doesn't work - I don't understand 
the reason. Isn't it a forward method which keeps the request parameters?
What is my misunderstanding?

Best regard and thanks
Thomas

Re: 1 ActionHandler and 2 ActionForms

[Ted Husted]

Are you trying to get two ActionForm beans populated, or use a different
form with the same Action at different times?

As it stands, the ActionServlet will try and populate whatever
ActionForm was specified for the request. 

That form is then passed to perform. 

Any ActionForm subclass can be passed to an Action. It just needs to
know which one to expect. You could determine that through reflection,
or looking at the type in the mapping, or via the generic parameter
property.

Country List

[Kevin J. Turner]

I am involved in converting a large Active Server Pages (ASP)
application to a JSP/Servlets solution, using the Struts framework. I am
new to Struts and I have a relatively okay grasp of JSP/Servlets/Struts.
 
A few of the pages in the current project use an ASP include file that
creates an HTML SELECT object of Country names and their corresponding
2-digit ISO codes.. The code is encapsulated in a function call, with
the country code to be selected passed in as a parameter, as follows:
 
--- snip ---
<%
Call CountryList("country", "CA")
%>
--- snip ---
 
which produces HTML similar to the following:
 
--- snip ---

  Canada
  United States
  France
  Fiji
  Finland
  ...
  etc

--- snip ---
 
I would like to duplicate this functionality using
JSP/Struts/JavaBeans.. whatever.. but I'm not sure the best way to do
it. Could some offer advice on what the most elegant approach to this
would be? The obvious goal would be to have a reusable component/module
that produces the necessary HTML based on a static list of country names
and codes, and to be able to pre-select a country.
 
Any advice is appreciated.
 
Regards,
 
Kevin J. Turner

Re: Country List

[Chris Opacki]

I believe you can get the information you need in the
Locale class. I'm pretty sure it has all of that
information in it. From there you may create a Helper
object that builds the options for the select
statement.

how about something like this - you could do a lot to improve this, but here
is the basic idea. Better yet, use a properties file or a database to
specify the country list. Then use the Collection returned from this method
from the  tag to create the option list for the select.

import java.util.Collection;
import .../.../LabelValueBean;

I am attempting to modify an application that works as follows:
1.  Bring up a form filled with data from master document.
2.  Click on button to bring up another "attachment" form.
3.  On attachment form, identify name and directory path of a
document to "attach" to the information on the main form.
4.  Click on "attach" button, process runs to link main document
with attachment and returns to main screen.

The goal is to redirect the attach button so it just returns itself to the
attachment screen so the users can attach multiple documents
at once without flipping back and forth between the master screen and the
attachment screen.  That I got going fine.  But it's the
return button that's causing this error when I try to direct it back to the
main screen.  I seem to have the key for the master document,
but I'm wondering if the complaint relates to the collection of attachment
objects.

Oh, and this is stateless. 

Has anyone seen this error before?

Subject: Country List


I am involved in converting a large Active Server Pages (ASP)
application to a JSP/Servlets solution, using the Struts framework. I am
new to Struts and I have a relatively okay grasp of JSP/Servlets/Struts.

A few of the pages in the current project use an ASP include file that
creates an HTML SELECT object of Country names and their corresponding
2-digit ISO codes.. The code is encapsulated in a function call, with
the country code to be selected passed in as a parameter, as follows:

--- snip ---
<%
Call CountryList("country", "CA")
%>
--- snip ---

which produces HTML similar to the following:

--- snip ---

  Canada
  United States
  France
  Fiji
  Finland
  ...
  etc

--- snip ---

I would like to duplicate this functionality using
JSP/Struts/JavaBeans.. whatever.. but I'm not sure the best way to do
it. Could some offer advice on what the most elegant approach to this
would be? The obvious goal would be to have a reusable component/module
that produces the necessary HTML based on a static list of country names
and codes, and to be able to pre-select a country.

Any advice is appreciated.

Regards,

Kevin J. Turner

FW: Servlet error - found answer in archives

[Lawrence, Jane K]

I hunted through the archives and found the solution to change to
redirect=true
in the struts-config file.  Did that and now I lose my key - any other
solutions?

I am attempting to modify an application that works as follows:
1.  Bring up a form filled with data from master document.
2.  Click on button to bring up another "attachment" form.
3.  On attachment form, identify name and directory path of a
document to "attach" to the information on the main form.
4.  Click on "attach" button, process runs to link main document
with attachment and returns to main screen.

The goal is to redirect the attach button so it just returns itself to the
attachment screen so the users can attach multiple documents
at once without flipping back and forth between the master screen and the
attachment screen.  That I got going fine.  But it's the
return button that's causing this error when I try to direct it back to the
main screen.  I seem to have the key for the master document,
but I'm wondering if the complaint relates to the collection of attachment
objects.

Oh, and this is stateless. 

Has anyone seen this error before?

Display Only Version

[Scott Walter]

Hi,

I have a page using Struts tags that I want to be able
to make the page editable in certain cases and display
only in others.

Is there an easy way to be able to have a display only
version of a struts-powered page without having to
write a second page?

RE: Display Only Version

[pritika.pattar]

Hi Scott,

You can maintain a session variable, say "allowEdit", which you can set
to True/False depending on your requirement. While displaying your page,
check for the value of the session variable "allowEdit". Set the value
of session variable in Action class of your page.

I would first look at the CountryList function and see where they are 
populating the data from (database, etc.).  Because you are just 
starting out, the simplest way might be to create a custom tablib that 
does the same thing.  Beans and taglibs are basically the same (java 
classes) but the interface is just a little different.  I would also 
check out the Local class because I think all of that info is already in 
there.

Also check out the Struts-Blank example webapp because it uses text from 
a resource file for display on the jsp page.  I think the language 
displayed is based on the language that the browser is using (I think). 
 This could do away with the select box completely and make the whole 
process automatic.
