RE: Combining struts and JSTL tags...

[Paul McCulloch]

This can happen if you have included the bean taglib twice. 

Is the page with which you get an error included via an <%@ include
statement?

Subject: RE: Combining struts and JSTL tags...


i haven't found a resolution to a problem previously posted under another
subject, since it fits this topic I thought
i'd put it out there again.

I started my app using struts tags, and recently incorporated jstl.

Unfortunately I get an error when I import both struts-bean.tld and c.tld

c.tld:   http://java.sun.com/jstl/core)
struts-bean.tld:
http://jakarta.apache.org/struts/tags-bean-1.0.2)

i.e. when these 2 taglib directives appear on a single .jsp

<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

i get the following exception:  jsp.error.tlv.invalid.page

null: org.xml.sax.SAXParseException: Attribute "xmlns:bean" was already
specified for element "jsp:root".

Any potential drawbacks with this design

[sreekant_gottimukkala]

Hi All,

Please give me your comments/suggestions on the below design.

I need to perform some common functionality across all the application
action classes, so I have written an abstract MyOwnAction class inheriting
from STRUTS Action class. All application action classes will be extending
MyOwnAction class. I have overridden the execute() method in MyOwnAction
class in which I am doing my desired common functionality. I am also
publishing an abstract method executeTask() which should be overridden by
the all the application action classes  The executeTask() method is called
by the execute() method of MOwnAction class. Basically the executeTask() is
now the method where the application action classes will write the
application code as opposed to execute().

This is a common approach that many application use.

The only possible "drawback" would be that a developer could bypass the 
common functionality by extending Action instead of your base Action 
class. But, in some cases, that might be preferable.

As mentioned, extending the RequestProcessor is another alternative, but 
not everyone is comfortable with that.

[sreekant_gottimukkala]

I did look into the subclassing the RequestProcessor class as well. I am
not sure if it can do the following
-- throw Exceptions.
-- NOT call the corresponding action class (instead return to a default
page) depending on some conditions.

Is there any advantage subclassing the RequestProcessor class as opposed to
the implementation I wrote below.

One way to do this is to assign actionForm1 to a property
in actionForm2 in the Action1.execute() method:

  ...
  ActionForm2 form2 = new ActionForm2();
  ...
  form2.setForm1(form1);
  // put form2 in the expected scope for sample2 action mapping
  ...
  return new ActionForward("/sample2.jsp");

Then you could use the nested properties in form1 for 
possible display in the sample2.jsp. And save them, if desired,
in the Action2.execute() method.

RE: Any potential drawbacks with this design

[Andrew Hill]

The difficulty with extending the RP occurs if not ALL the actions need this
common functionality. Where this is the case your design is a good one. (I
have used it to great effect in my own apps already).
Id suggest you continue with this method. If you have other developers on
the project make sure they know to extend your class if they need that
functionality. You might also wish to declare the execute() method in your
base class final so that they dont inadvertantly override it.

Struts action in the

[John Leonard]

I've been exploring the co-mingling of container-based security and struts
actions through FORM-based authentication.  While many options have been
presented and discussed (including subclassing the Action and directly
calling container-managed security methods), it seems to me (a newbie) that
one obvious solution has not been addressed:

What are the side-effects of directly pointing the error and login pages
directly to a struts action (in the example below /login.do) , rather than
to an HTML or JSP file?  For example:


  FORM
  
/login.do
/loginError.do
  


And in the view of the login form:


  Username: 
  Password: 


If this won't work, what about pointing the login and error pages to a JSP,
and using a  or a  tag in the file to handle
the request through struts?

Am I missing something subtle (or not so subtle)?  Thanks in advance.

RE: Any potential drawbacks with this design

[Mainguy, Mike]

I'm interested in folks response to this also.  This is the approach I have
used on 2 different projects and seems to work very nicely.  In addition, I
modified the signature of my abstract method (in this case executeTask) to
take a custom ActionForm with some additional functionality.  It seems to be
a convenient way to provide extra/common functionality for "free" using
inheritance, but, I'd like to hear if anyone can think of any significant
disadvantages to doing it this way.

click on button-->save data-->go to another page?

[Rick Col]

Hi,

If I have a go button like this:



once I click on this button on sample1.jsp, I want to
save some data to
database, then go to another jsp page sample2.jsp. I
definne
an action class to handle data saving.

Thus, once user clicks on go button, user should be
directed to
the data saving action class first to save data, then
go to
sample.jsp page. In struts-config, I define mapping as
the following:



Will that work?

And I am not sure how I can make "go" button go to
action class first and save data, then go to
sample12.jsp?

RE: Create new nested bean instance

[Nate Drake]

Robert,

Thanks for the links.  I already read the Indexed Property FAQ (and I
just re-read it again), but I didn't really see anything in it that
relates to my problem.  

The lazyList stuff looks more promising.  I have a question about it,
though. Where do I create the new LazyList?  In the ActionForms reset()
method?

Thanks again.

[Jing Zhou]

There is no *drawbacks* or *advantage* design in regard to
extending Action or RequestProcessor. It depends.

The key is how you actually interpret the word "common":

-If the *common* functionality is applicable to *all* action
mappings in a given application module, you do it by
extending RequestProcessor. For example, a custom
security checking facility in RequestProcessor.

-If the *common* functionality is required to happen
before certain logic you do it by extending RequestProcessor.
For example, a custom form token checking facility
before the form bean population.

-If the *common* functionality is applicable to a sub
set of Action classes in the application module, then you do it
by extending Action. For example, a CRUD operation
for a set of business entities. And you also give other
developers a way to interpret the CRUD operation
differently when they see fit.

I could see you have good reasons to extend Action.

RE: click on button-->save data-->go to another page?

[Paul McCulloch]

The action class that handles the saving of your data returns an
ActionForward - your execute() code determines what that forward is.

To go to sample2.jsp you want to end your execute() with:

return mapping.findForward("sample2");

Hi,

If I have a go button like this:



once I click on this button on sample1.jsp, I want to
save some data to
database, then go to another jsp page sample2.jsp. I
definne
an action class to handle data saving.

Thus, once user clicks on go button, user should be
directed to
the data saving action class first to save data, then
go to
sample.jsp page. In struts-config, I define mapping as
the following:



Will that work?

And I am not sure how I can make "go" button go to

[OT] How to get an object stored in ServletContext from a SessionBean?

[OFlaherty, Colm]

Hi, 

I know this is a bit OT, but here it is: any help is much appreciated.

This relates to the Hibernate Plugin for Struts.. 

How do I get a handle on the SessionFactory that is stored in the ServletContext??  
(From a SessionBean, that is)

The following is a shortened (an uncompiled!) version of how the SessionFactory is 
stored... 

Colm



import org.apache.struts.action.PlugIn;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
import java.net.URL;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;

public class HibernatePlugIn implements PlugIn 
{
public void init(ActionServlet servlet, ModuleConfig config)throws 
ServletException 
{
Configuration configuration = null;
URL configFileURL = null;
private SessionFactory factory = null;
ServletContext context = null;

configFileURL = new URL ("/hibernate.cfg.xml");

configuration = (new Configuration()).configure(configFileURL);
factory = configuration.buildSessionFactory();

context = servlet.getServletContext();
context.setAttribute(SessionFactory.class.getName(), factory);
}   
}

image property

[Das, Amar]

Hi,

The struts documentation of attribute "property" for image tag says that
"The property name of this image tag. The parameter names for the request
will appear as "property.x" and "property.y", the x and y representing the
coordinates of the mouse click for the image. A way of retrieving these
values through a form bean is to define getX(), getY(), setX(), and setY()
methods, and specify your property as a blank string (property="")"

The image tag does not have a name or id attribute.  If I have more than one
image tag in a form how do I differentiate one getX() from another?  For
example, let consider that I have two image tags in my form.  The ActionForm
has the following lines

public class MyForm extends ActionForm {
private String x;

public String getX(){
return(this.x);
}
..

Following the documentation how do I get the value of x in my JSP page?  And
how do I differentiate x values for the two image tags?

Thanks in advance

Are you sure the value isn't getting reset before it gets to your page? I
assume no exceptions are being thrown which prevent the field from
initializing, I saw earlier you're initializing this value in the
constructor.  What happens if you just leave the value assigned from the
private instance var and have the accessor retrive that w/o the stuff in the
constructor?

simple question

[harm]

Hi all,

I think I have a relative easy question.

I have a J2EE application which has some entitybeans. I want to display 
the values of these entitybeans in my JSP pages (using Struts).
I have made value objects of the entitybeans. 

In my ListAllCategoriesAction.java, I do something like the following:

Collection allCategories = mySessionFacade.getAllCategories();
DisplayBean displayBean = new DisplayBean();
displayBean.setCategories(allCategories);
request.setAttribute("categories", displayBean);
return mapping.findforward( SUCCESS );

As you can see I'm using a special bean (displayBean) to pass the 
categories to my JSP page. In my JSP page I use the  tags 
to iterate through te collection and display the proper information.

Is this a normal / good approach? Or do I have to use ActionForm classes 
for this purpose?

Thanks a lot,

RE: Any potential drawbacks with this design

[Andrew Hill]

Jing sums up the situation well.
One point to add :- if it (the functionality) is applicable to all the
actions today and you decide to go with the RP approach, that doesnt mean
that tomorrow you wont suddenly need to add an action to which it should NOT
be applied - at which point you will then either have to factor it out of
the RP into some base action anyway - or do it conditional on checking some
flag - at which point you run the risk of introducing action logics into the
RP...

My votes with the Action approach :-)

Plug-in API

Hi
I am just trying to learn about the Plug-in API.

When exactly is this useful ? How would it be helpful if I want to
plug-in a custom-user authentication facility instead of using the

RE: simple question

[Mohan Radhakrishnan]

Yes. This is a normal approach.
 ActionForms are used only if you want to pre-populate data. i.e If you have
to show default values in a text field you can pre-populate the Action Form
and forward to a JSP.

  You can also store a Collection directly in one of the scopes and show
that but Custom beans like this are useful because they can be manipulated
quite well with the tag handlers.

Plugins are really only helpful to people using a Servlet 2.2 container. 
If you're using Servlet 2.3 you should use a ServletContextListener.

Struts Plug-In is useful any time you have a resource that needs to be 
initialized with the web application. In the past you would have needed 
to extend the ActionServlet and override init(), now you declare a 
plug-in in your struts-config.xml

I don't know (but I doubt) that there is a determinate order to how 
containers process "contextInitialized"  On the other hand, Struts 
processes plugins in order.  I know one developer who leverages this 
predictability to initialize a series of "specialist" classes, and 
then finally a facade type class which proxies for the others.  I 
don't know the details, but this is one other possible use case.

Also, PlugIns are "module aware" -- the initialize method gets a 
ModuleConfig object.  That might matter to some implementations.

I suspect in many cases where I use PlugIns, I could be using 
ServletContextListeners instead, but I haven't broken the habit yet. 
But the gist is the same -- some component you write needs to know 
when the application context has been initialized.

That's really the only reason I can think of to use PlugIns instead of the

[Validator] E-Mail Verification

[Jerry Jalenak]

Is there a published specification on e-mail addresses?  The reason I ask is
that we are using the 'email' validator, and it's accepting as valid e-mail
addresses such as 'u-+-+%^_/[EMAIL PROTECTED]'.  I didn't think Validator
would accept these, but apparently is it.  If there's not an established
spec for e-mail addresses, then I would assume that anything goes

There was discussion about this earlier on the mailing
list. Search the archives for "email validation RFC"
or some such.

There's an RFC that covers what're valid email addresses.

Your example looks perfectly valid to me...

TMC Petshop, java performance tuning, struts

[tum curtin]

I have recently read the results paper from the
second benchmark test run by The Middleware
Company (TMC) comparing the performance of the
Petshop application using Java solution
and .NET solutions.
(http://www.middleware-company.com/casestudy/tmc-performance-study-jul-2003.pdf)
This paper would be very useful I believe
to anyone who is interested in fine tuning the
performance of their application and server.
IMO the results paper seems to suggest that Java
solutions can be just as fast as .NET solutions
but that some Java solutions can be much much worse.
In particular, a java solution using struts is
unlikely to perform as well as a solution that does
not use some form of introspection (as struts does to
populate beans from forms).  I have several questions
regarding these conclusions.
1.  Are they accurate based on the evidence presented
in the study
2.  Does anyone know the identities of the two java
servers used in the study
3.  In using struts does the productivity gains outway
the performance cost and can this performance cost
be adequately mitigated by upgrading hardware.
4.  Have any similar tests been run in which the Java
servers are run on Unix platforms instead of
Windows Server 2003.
5.  Has anyone performing tests on their own struts
apps found similar results concerning the high
costs of the introspection process.

What you are doing should be fine (as long as your collection is not too terribly big).
You use an ActionForm when you want to collect input from the user.

Hi all,

I think I have a relative easy question.

I have a J2EE application which has some entitybeans. I want to display 
the values of these entitybeans in my JSP pages (using Struts).
I have made value objects of the entitybeans. 

In my ListAllCategoriesAction.java, I do something like the following:

Collection allCategories = mySessionFacade.getAllCategories();
DisplayBean displayBean = new DisplayBean();
displayBean.setCategories(allCategories);
request.setAttribute("categories", displayBean);
return mapping.findforward( SUCCESS );

As you can see I'm using a special bean (displayBean) to pass the 
categories to my JSP page. In my JSP page I use the  tags 
to iterate through te collection and display the proper information.

Is this a normal / good approach? Or do I have to use ActionForm classes 
for this purpose?

Thanks a lot,

Tiles problem?

[Roland Berger]

Hi all

I have JSP code which used to work with older struts versions (1.1 beta xy).
Now I use struts 1.1 stable release.

I have  two jsp pages. I want to nest JSPPage2 into JSPPage1 with
 ( see JSPCode ). All I get is "[ServletException
in:/WEB-INF/pages/JSPPage2.jsp] Cannot find bean in any scope'"
With debugging I have found out that JSP Page 2 losses the parent context (I
mean the bean which is assosiated to the /RegisterAddressAction.do action in
struts-config.xml). How can I handle over the parent context to the nested
JSPPage2 tile?

RE: iterator tag

[Yansheng Lin]

You sure?  'cause normally what I got is just nothing if the list is empty.  

If the collection you are iterating over contain null values, the loop will
still be performed   but no page scope attribute (named by the id attribute)
will be created for that loop iteration. You can use the  and
 tags to test for this case.

However, the *brand new* collection has to be defined somehow, i.e., itself
cannot be null.

Hope this helps.

You're better off writing your own.  RFC 822 is very generous because it 
doesn't just deal with remote internet addresses, but email from all sorts 
of networks.

Here's an example of something that's a bit more restrictive.

This first runs it through javax.mail.internet.InternetAddress().  You'll 
need to have the javax.mail package installed to use it.

Then it performs additional restrictions (we want to disallow local 
addresses).


private boolean isRemoteAddressSyntax(String emailAddress)
{
int firstAtPos = emailAddress.indexOf('@');
int lastAtIndexOf = emailAddress.lastIndexOf('@');
int lastDotIndexOf = emailAddress.lastIndexOf('.');

// Must be one @
if (-1 == firstAtPos)  return false;

// Must be at least one character before @
if (1 > firstAtPos)  return false;

// Must be at least one '.'
if (-1 == lastDotIndexOf)  return false;

// Only one @ allowed.
if (firstAtPos != lastAtIndexOf)  return false;

// '.' must be at least one character after '@'
if (lastDotIndexOf < (firstAtPos + 2))  return false;

// Must be at least one character after '.'
if (lastDotIndexOf == (emailAddress.length() - 1))  return false;

return true;
}

public boolean isValidBasicEmailSyntax(String emailAddress)
{
try
{
javax.mail.internet.InternetAddress anAddress = new 
javax.mail.internet.InternetAddress(emailAddress);

return isRemoteAddressSyntax(emailAddress);
}
catch(javax.mail.internet.AddressException anAddressException)
{
return false;
}

I would presume they are accurately measured (have no way to verify), but
the key to understanding this test is the description of the testing
scenario.  They spent a LOT of time tuning things so that the database and
network were not bottlenecks; the goal being to measure the CPU time in
the middle tier.  While that's interesting, how often is it relevant in
the real world, where database and network latencies are the normal
bottlenecks to response time?

For the first part of this question, you need to determine if it even
matters in your particular app.  For the second part, it's mitigated by
adding more/faster CPUs.

I did some microbenchmarks on the commons-beanutils code that is in turn
used by Struts -- see the message archives for the
[EMAIL PROTECTED] mailing list and search for
"microbenchmarks".  A couple of things my tests showed were pretty
interesting:

* When using BeanUtils.copyProperties() or PropertyUtils.copyProperties(),
  using a DynaActionForm (which uses a HashMap but no reflection) is
  actually faster than using standard ActionForm beans.

* The BeanUtils.populate() method -- which is expressly tuned to deal
  with copying request attributes into your form bean -- is substantially
  faster than BeanUtils.copyProperties() is.

* As expected, recent JVMs are substantially faster than earlier ones
  at reflection-based processing.

It can only possibly matter if CPU time on your middle tier server (the
one running your webapps) is your response time bottleneck.  Is it for
you?  If so, then this matters.  If not, then it probably doesn't.

IMHO, the most important single issue for performance of Struts based apps
is the quality of your JSP page compiler.  Just as an example, the Tomcat
admin app is Struts based, and the difference between running it against
an early 4.0.x version versus current 4.1.x or 5.0.x versions is night and
day -- six times to eight times faster, and visibly more responsive even
in a single user environment.  If you're looking for performance
improvements, in general you should focus on:
* JDK you're running
* JSP page compiler
* Servlet container you're running
* Database tuning
* Network tuning

before getting to the minutiae of CPU time comparisons for things like
reflection.

RE: Create new nested bean instance

[Nate Drake]

Ok, the thing I don't understand now is how to setup the
AddNewPhoneNumber jsp so that is uses the lazy list to create a new
PhoneNumber instance bean.

I'm trying to use the nested taglib, but I don't really understand how
to set the top level object to be a new instance out of the list.

I've tried something like this:


  
  
  
  


The thing I can't figure out is how you set the top-level object to be a
new instance of the PhoneNumber bean (which should be created from the
lazy list).  I tried using , but
that gives me an error stating "No getter for property
phoneNumbers.countryCode of bean customerForm".  I figure that is
because the  sets the top-level object to be the List, and
doesn't actually attempt to get an item out of the list (which would
cause the lazy list factory to create a new PhoneNumber instance).  

How is this supposed to work?  Am I on the right track at all?  Anyone
have a link to an example like what I'm trying to do?  

Thanks.

RE: Searching facility questions

Hide your .jsp files in /WEB-INF/foo (I use /WEB-INF/pages) so that the user
cannot navigate directly to them.  Alternatively hide them ANYWHERE so they
cannot directly link to them.

Ok, let's say that I would like to translate system's specific URLs (i.e.
D:\Tomcat\webapps\foo\foo\bar.jsp and so on...) into  web-context specific
URLs (i.e. http://myServer/foo/foo/bar.jsp). Well, if I immagine to replace
D:\Tomcat\webapps with http://myServer things seem quite easy. My first
question is: did anyone encountered this problem before?

Secondly a JSP page not necessarily can be
executed without passing from a Struts Action (i.e. an Action prepared some
data to display, and if we try to access the JSP directly we could have some
bad 5 minutes), so my question is: did anyone encountered this kind of
problem? Did you find any solution? For this second subject, I could think
to a sort of mapping file between JSPs and relevant actions, so that we can
assume that if the user clicks on a JSP link, instead the relevant action
for that JSP will be executed and then the JSP displayed. The mainteinance
for this solution seems CRAP.

Hope someone of you will help,

Marco

How about documentation folder and jsp files, where would you put them?

BTW, I was studying a tool called Maven on Apache.  I think it's more relevant
to project structure than Ant.  Ant is more related to building a project, isn't
it?  Is there a standard project model/pattern out there we can just follow?

What a well defined struts project structure would look like?  I am always a
bit
hesitant with where to put things

Right now, I have:

MyProject   
  |- documentation
  |- images
  |- jsps
|- styles
|- javascript
  |- WEB-INF
  |- classes
  |- bin
struts-config.xml
  *.tld
  project.xml
  ...

But I always run into problems with too many files in one folder or too few
files in one folder.  I searched the apache CVS tree, and found that it's a
mess
there too.  Just compare Tomcat and Struts, you will know what I am talking
about.

Hi All,

We recently ported the weblogic server from SP1 to SP4 and came accross the 
following problem while displaying the JSP pages. This was working fine on SP1. 
Can anyone tell me the possible reason.

The line of code in the jsp is :


where 53 is a input parameter of getName(int size) method of FormBean.

RE: Struts 1.0 problem

You want to make sure that formBean you compiled has only the simple bean
class itself and nothing more, i.e. there is no other BeanInfo class compile
with it.  This once time my co-worker accidentally hit some bean wizard in
Jbuilder and it generate some BeanInfo class that get compiled and he has
the exact oout come like yours.

How to pass urlparameters to findForward?

[Srinivas Gunturu]

Hi,

I need to pass parameters depending on user action to my findForward.  

I have tried the following but does not seem to be working.

String urlQueryString = getURLParameters(nextURL);
if ( urlQueryString != null && urlQueryString.length() > 0 ) {
ActionForward forward = aMapping.findForward(nextURL);
StringBuffer path = new StringBuffer(forward.getPath());
path.append("?" + urlQueryString);
forward = new RedirectingActionForward(path.toString());   
 
return forward;
} else {
return aMapping.findForward(nextURL);
}

I have also tried setting my parameters on request using request.setAttribute

This also did not work.

I have also searched on net for 2 hours and no luck.  Please help!

TIA

RE: Create new nested bean instance

[Robert Taylor]

Sorry Nate, I can't help you with updating your structures using the
nested taglib. I haven't done it before. Maybe someone else can provide
you some guidance there so that you don't have to jump through the
indexed properties "hoops".

On the other hand, using indexed properties:

Your form must have getPhoneNumbers(int index) and setPhoneNumbers(int
index)
methods.

Ultimately you want the HTML syntax to be something like:






Where the index of 2 is the nth location for your new phone number.
You could pass 'n' as a request parameter when the user clicks on
the "Add New Phone Number" link.

Since the nth location doesn't exist, the lazy list will create an empty
PhoneNumberBean object and add it to the list in the nth location anytime
when a get() or set() is invoked on a location that does not exist.
This is all in the documentation which I'm sure you've read by now.

So one way to achieve the HTML syntax listed above, is something like
the following where 'n' is a request parameter named 'topLevelIndex':

<%String prefix = "phoneNumbers[" + request.getParameter("topLevelIndex") +
"]";%>
"/>
"/>
"/>
"/>

There are more slick ways to do this using JTSL or Struts-el but if you just
want to
get it working first, you can try the above.

What should happen when your form is displayed is that the 
tag will
look up (finally delegating to PropertyUtils) the indexed properties and
attempt to get any existing value by invoking
the getPhoneNumbers{index). The List implementation provided by the lazy
list
will determine that no object exists at the specified location and it will
create an empty PhoneNumberBean object and populate the list and then
delegate to the
get(index) which will retrieve the empty bean property. This prevents the
dreaded
ArrayIndexOutOfBoundsException.

When your form is submitted, Struts sets the appropriate PhoneNumberBean and
then you can
procede with your business logic.


Nate, I hope this makes sense. Sorry I couldn' help you with using nested
taglib to accomplish
this. I assume you have already looked here:

I believe that the name part needs to be quoted. However, I believe 
currently validator will still
count this as a valid email. I haven't gotten around to tweaking the 
regexp. To handle these cases
the user name pattern/expression will need to increase in complexity by 
a factor of 3 or so.
How about an option that would allow only struct user names checking,

versions of the regexp
need to change. I believe I would actually like to make the client side 
checking more course,
ie allow any email in the form of [EMAIL PROTECTED], then let the java take care 
of full validation,
what do you think ?



Unfortunately, I think that's a valid email address as defined in the RFC.

[ANN] Internet IDE - Carrier 2.0 b2

[Jing Zhou]

A solid release of Netspread Carrier 2.0 b2 is available today.
The Carrier client, a visual design environment on Internet, is
tested with JRE 1.4.2 with performance surprising my VB
friends.

There are two new things I am very proud of:

1) A Form Token Facility is introduced to automatically protect
every web form and every hyper link in application modules with
no-cache turned on. The facility is completely hidden from 
the views of designers and can be turned on/off programmatically.

2) The Carrier Developer's Guide is near completed in which
the LocalizedDate class is examined in details. The four
key attributes, input format, output format, format pattern
(or a key to the localized pattern), and error key, are completely
encapsulated in the class. Therefore designers only need to
register this class in a form bean property descriptor with
desired format pattern or its key in ONE place. I see other
methodologies make the designers to register input format here,
output format there, pattern in another configuration file...
causing endless troubles just for a simple Date property.
Now the problem is solved in the cleanest way. It is a 
complete i18n java.sql.Date property to my knowledge and
it tells us almost any other complex properties could be
designed this way. See it with composing screen shots at
http://www.netspread.com/developer.html#FormBeanValidations


Carrier is designed to be used by sloppy users like many of
us in this list. It doesn't tell you "How easy to write codes
to do it", instead, it tells you "How easy to compose web
forms to do it" with the capability of CRUD operations for hierarchical
and/or tabular data entries. It also tells you "Where you put
wrong things" in case configuration errors occur. It is a solid
commercial grade product for you to enjoy, no suffering.

If you complain any parts of it, tell us. User experience is on
top of the priority list. Do not forget to follow the 24 tips
on Wheels and Struts when you play it

And that's the problem. The  syntax above says that "name" is an array, and
that you want element number 53 of that array. That's exactly what the error
message is saying (Property 'name' is not indexed).

You could get around this with some more Java code :

<%
String name = formBean.name(53);
%>

+1.  Javascript is merely a convenience for the user and it's a pain to
maintain this complex logic in 2 places.

That's missing several perfectly valid characters
in Email addresses, like a space, +, single quote,
etc.

The RFC defines the valid characters for a reason.

This would be a new option for people who want to limit email addresses to
more reasonable characters than the RFC defines.  It would not be enabled

RE: Create new nested bean instance

[Nate Drake]

Thanks a million, Robert!  I got it 99% working the way you described.

The object in the list (PhoneNumber) has an
org.apache.struts.upload.FormFile property.  When I go to the
AddNewPhoneNumber.jsp I get:

java.lang.NoClassDefFoundError: org/apache/struts/upload/FormFile

I tried adding a <@page import%> to include
org.apache.struts.upload.FormFile in the jsp, but that didn't help.  If
I remove the FormFile property from the bean/jsp everything works
great.  I don't understand how it can't find this class.  It seems to
find the Struts taglib classes fine, but not FormFile. The taglib
classes and org.apache.struts.upload.FormFile are in the same jar.  I
really hate Classloader related problems.

Any ideas?

Thanks again for all your help.

Nate

RE: Create new nested bean instance

[Nate Drake]

Thanks a million, Robert!  I got it 99% working the way you described.

The object in the list (PhoneNumber) has an
org.apache.struts.upload.FormFile property.  When I go to the
AddNewPhoneNumber.jsp I get:

java.lang.NoClassDefFoundError: org/apache/struts/upload/FormFile

I tried adding a <@page import%> to include
org.apache.struts.upload.FormFile in the jsp, but that didn't help.  If
I remove the FormFile property from the bean/jsp everything works
great.  I don't understand how it can't find this class.  It seems to
find the Struts taglib classes fine, but not FormFile. The taglib
classes and org.apache.struts.upload.FormFile are in the same jar.  I
really hate Classloader related problems.

Any ideas?

Thanks again for all your help.

Nate

RE: Converting a ResultSet to a List of POJOs

[Matt Raible]

Thanks to all for your suggestions.  I did some number comparisons b/w the
"standard" way (rs.next() ... set, set, set), ibatis, and
ResultSetUtils.getCollection() from scaffold.  Here's what I found:

1.  Standard way - 0.24 seconds
2.  ibatis - 5+ seconds (ugh! - maybe I'm doing something wrong, more info
here: http://tinyurl.com/mod4)
3.  ResultSetUtils.getCollection - 0.27 seconds

So I'm going with #3 as it'll speed up dev time and doesn't have much of a
performance hit.

Thanks,

Matt

You sure?  'cause normally what I got is just nothing if the list is empty.


If the collection you are iterating over contain null values, the loop will
still be performed   but no page scope attribute (named by the id attribute)
will be created for that loop iteration. You can use the  and
 tags to test for this case.

However, the *brand new* collection has to be defined somehow, i.e., itself
cannot be null.

Hope this helps.

This can happen if you have included the bean taglib twice.

i haven't found a resolution to a problem previously posted under another

i'd put it out there again.

I started my app using struts tags, and recently incorporated jstl.

Unfortunately I get an error when I import both struts-bean.tld and c.tld

c.tld:   http://java.sun.com/jstl/core)
struts-bean.tld:

indexed properties

[Michael Muller]

The following article seems to differ in approach from how the posters 
to this forum implement indexed properties in struts:

http://www.developer.com/java/other/article.php/2233591

In this article, the author uses a DynaActionForm which automatically 
builds an array of "normal" beans.  By "normal", I mean that the beans 
have methods like this:

String getFoo()
void setFoo(String foo)
rather than this, as is often advocated in this forum:

String getFoo(int index)
void setFoo(String foo, int index)
I prefer the former approach except for one minor factor: it doesn't 
seem to work.   :(

Struts seems to be creating me a valid form.  I say this becuase I have 
an iterator on my form that displays the right number of rows of text 
boxes, and they all have names like "mybean[0].foo".  Furthermore, if I 
change the "property" attribute of my "html:text" tag to "bar", I get an 
exception when I render the page that there is no "bar" property.

So things seem to be working well, up to this point, but in the 
implementation of the action, my form bean doesn't have any values set. 
 They're not even blank; they're null.  I stuck a println in a setter 
method -- it's not even being called.

I can, however, see the values in the request parameters if I print them 
out in the implementation of the action.

Help!  Actual code follows.

Thanks in advance,

RE: Redisplaying of entered form fields

[Rodney Paul]

Hi Andrew,

All of my struts actions have the redirect flag as false.
Here is more of my configurtion code which is used to run the application I am running.
Would be most appreciative if you could have a look.

CODE:
Below the code you see is part of an application I am building.
The problem here lies in the fact that in all cases,
field data does not get redisplayed within the form the user has entered data in.

eg. if you enter a invalid data within a numeric data field (this instance ACN)
then the ActionForm issues a error message gets issued (works)
but the ACN previously entered does not get redisplayed in the form.

eg. if you enter a valid ACN or Organisation Name within the fields to do searches,
and no data is applicable to the search criteria entered a error message gets 
issued (works)
but no ACN/Organisation Name gets redisplayed in the form where the data was 
entered.



Part 1: Sample Configuration (struts-config.xml)

























PART 2: Application form code (validation and reset methods)

public class OrganisationNameSearchActionForm extends ActionForm {

public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest 
httpServletRequest) {
ActionErrors errors = new ActionErrors();

if(method.equals("Next")) {
if((organisationName == null) || (organisationName.trim().equals(""))) {
errors.add("organisationName", new 
ActionError("error.organisationName.required"));
}

if((ACN != null) && (!ACN.trim().equals(""))) {
try {
Integer.parseInt(ACN);
}
catch(NumberFormatException e) {
errors.add("ACN", new ActionError("error.ACN.format"));
}
}
}

return errors;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
this.method = null;
this.organisationName = null;
this.ACN = null;
}
}

public class OrganisationNameSearchAction extends LookupDispatchAction {

Map map = new HashMap();
map.put("button.next", "next");

Firstly check that redirect is false in the forward to the view.
(If it is already false then thats not the problem and you should post some
more of your code and configs so we can try and see whats going wrong.)

Jing sums up the situation well.
One point to add :- if it (the functionality) is applicable to all the
actions today and you decide to go with the RP approach, that doesnt mean
that tomorrow you wont suddenly need to add an action to which it should
NOT
be applied - at which point you will then either have to factor it out of
the RP into some base action anyway - or do it conditional on checking some
flag - at which point you run the risk of introducing action logics into
the
RP...

My votes with the Action approach :-)

There is no *drawbacks* or *advantage* design in regard to
extending Action or RequestProcessor. It depends.

The key is how you actually interpret the word "common":

-If the *common* functionality is applicable to *all* action
mappings in a given application module, you do it by
extending RequestProcessor. For example, a custom
security checking facility in RequestProcessor.

-If the *common* functionality is required to happen
before certain logic you do it by extending RequestProcessor.
For example, a custom form token checking facility
before the form bean population.

-If the *common* functionality is applicable to a sub
set of Action classes in the application module, then you do it
by extending Action. For example, a CRUD operation
for a set of business entities. And you also give other
developers a way to interpret the CRUD operation
differently when they see fit.

I could see you have good reasons to extend Action.

Re: why servlet as controller in MVC

[Max Cooper]

That is kind of an open-ended question, but here are two alternatives
and some problems associated with them:

1. Filter -- some containers require that a request really does map to a
resource, so even if the Filter mapping matched the request you could
end up with 404 errors in the case where the resource doesn't exist. One
way to avoid this would be to have each request map to a JSP directly,
but that would be pretty confusing if the controller decided to map the
request to some other JSP (or some other, similar view resource) instead
of passing it down the chain to the indicated JSP. Some Actions have
some kind of switching behavior to route the request to one of a number
of view resources.

2. JSP -- the controller normally passes the request to a view resource
(like a JSP) but doesn't produce the response directly. JSPs are best
suited to producing a response (usually HTML) directly, where a servlet
better matches the needs of writing a controller. Other view-oriented
technologies are similar to JSPs, and many use their own servlet to
process the requests anyway.

Since those don't work so well, a Servlet turns out to be a good match
for the needs of the controller component in comparison.

It sounds like you might have something else in mind -- what alternative
implementation strategy are you thinking of?

Redisplaying of entered form fields

[Rodney Paul]

Hi All,

I have a problem redisplaying form fields a user enters within a html form.

I use the validate method to validate form entry fields through ActionForms.
and validate business logic in LookupDispatchAction classes.

Has anyone experienced this problem, and is there any solution to this
matter.

Cheers
Rodney



CODE:
Below the code you see is part of an application I am building.
The problem here lies in the fact that in all cases,
field data does not get redisplayed within the form the user has entered data in.

eg. if you enter a invalid data within a numeric data field (this instance ACN)
then the ActionForm issues a error message gets issued (works)
but the ACN previously entered does not get redisplayed in the form.

eg. if you enter a valid ACN or Organisation Name within the fields to do searches,
and no data is applicable to the search criteria entered a error message gets 
issued (works)
but no ACN/Organisation Name gets redisplayed in the form where the data was 
entered.



Part 1: Sample Configuration (struts-config.xml)

























PART 2: Application form code (validation and reset methods)

public class OrganisationNameSearchActionForm extends ActionForm {

// Get and Set methods


public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest 
httpServletRequest) {
ActionErrors errors = new ActionErrors();

if(method.equals("Next")) {
if((organisationName == null) || (organisationName.trim().equals(""))) {
errors.add("organisationName", new 
ActionError("error.organisationName.required"));
}

if((ACN != null) && (!ACN.trim().equals(""))) {
try {
Integer.parseInt(ACN);
}
catch(NumberFormatException e) {
errors.add("ACN", new ActionError("error.ACN.format"));
}
}
}

return errors;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
this.method = null;
this.organisationName = null;
this.ACN = null;
}
}

Part 3: Action Code (Sample)

public class OrganisationNameSearchAction extends LookupDispatchAction {
protected java.util.Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.next", "next");
return map;
}

HttpSession session = request.getSession(false);

RE: Searching facility questions

[Marco Tedone]

Well Mike, my problem is not to avoid user from accessing JSP directly, but
to show her a list of links with a meaning as a result of a search action.
The problem is even worst, if you think that I'm using Tiles, with the
actual web content in JSPs which are never accessed directly neither by a
Struts action, but imported as defined in the Tiles definition file.

Did anyone realize a search facility which runs on a Struts application
running Tiles? How did you solve the problem:

content-linkable mappings?

I'm thinking to create a configuration file with a mapping between the
content JSP pages and meaningful Struts action links. The search facility
will return a list of meaningless paths to JSPs containing the actual
website content, and a class will search for the Struts mapping between
those links and linkable actions.

Does it make sense? (here he was looking around with a very interrogative
expression...)

Hide your .jsp files in /WEB-INF/foo (I use /WEB-INF/pages) so that the user

ActionForm's reset method is invoked twice ??

[Fumitada Hattori]

Hi gurus,

I wanna know that ActionForm's reset method is invoked twice ?
There's an action tag in my struts-config.xml.

 


and I got a jsp named test.jsp


  


With my application, seems that both when I visite the test.jsp 
and I click the submit button, reset method is invoked.

Is it a normal operation ?

Thanks in advance.

Eliminating Redundancy...

[alan]

I'm creating a struts application and I would like to have all of my
constants in a single file, perhaps my application's resource bundle.
I'd like this data to contain such info as the maximum length of various
input fields (eg cityLengthMax = 100) and be able to refer to this in my
validation.xml file for input validation.  At the moment I seem to have
to hard code these values in the validation.xml file.
 
Is this possible?  Can I use vars in the validation.xml file that refer
to values in another file.  I'd like to use the same constant lengths in
multiple applications (because they use the same columns in the same
tables in the same database).
 
At the moment I'm forced to do this.
 

cityLengthMax
10

 
Whereas I'd like that 10 to be a pointer to a value held elsewhere.

Re: Converting a ResultSet to a List of POJOs

[K.C. Baltz]

Since I had to look it up, maybe others did too:

POJO = Plain Old Java Object.

I'm guessing that means a Java object that doesn't need to know how it 
is persisted in order to be stored?  I.e., in Matt's case, the object 
isn't modified to take ResultSet as an argument to the constructor.
