I have a list of items in DB:
ITEMS contain rows ID and NAME

I would like to know what is the recommended way to have a form that
lets the user select an option from the database list of items and when
the uses clicks the preview action the selected item is shown prior to
the last action of confirmation.

Should I get the list of items from the form?
(setting it in the form does not make sense to me as a form is just for
user input and that list is not user input)
Or from the action? (request.setAttribute())
(setting them from the action associates that list with a view and I am
only supposed to let the controller know what to do next not what view to
display)
Or from any other place?

Could someone show me the recommended way on how to do it showing me the
Form(s), Actions and struts-config.xml?

http://struts.apache.org/2.x/docs/building-the-framework-from-source.html

The instructions are pretty straight-forward. If you've
never used maven
before, it's a bit tricky at first, but once you run
through it a few
times, it's pretty easy. If you're building from
trunk, then you might
want to grab the XWork2 sources and build them as well -

I upgraded my app to Struts2, which provides file uploading.  Now my custom
servlet for uploading an attachment no longer receives the request.  Is
there a configurable option for restoring the old functionality of having
the custom servlet upload the attachment?  Thanks.

FYI - 1) Initially an exception was thrown as a result of
FilterDispatcher.doFilter handing off multipart handling.  This was due to
a jar mismatch. So, I got the correct versions of the commons-io.jar and
commons-fileupload.jar, and the exception is gone. But my servlet never
receives the request. 2) I have a custom interceptor stack containing
defaultStack.  That means the fileUpload interceptor is available.

If you don't need the file-upload interceptor then remove it from your
interceptor stack or exclude it for those actions which rely on your
custom fileupload-servlet.

What old functionality? You don't mention what you upgraded *from*...
Struts 1? In any case, it sounds like the problem is probably a conflict
in you servlet/filter mappings in web.xml.

The obvious question is, why use a custom servlet to handle uploads,
rather than let Struts deal with it for you? Does your servlet do some
special processing you can't easily migrate into an action?

Hi,

thanks for the hint, but I used namespace="/secure" already. Only typed
it wrong into the mail.
Also compared namespace names between struts.xml and my nav.jsp. Thats
also correct, so I looked if the user (a variable in the session) is
null. But the user is not null.
So it looks like there is another problem with the lib which connect to
LDAP server.

As I can see for the moment I have no problem with the session but with
my user object.

Cheers,
Michael

It could be that you have an empty collection, so the bean is present
but it is empty, and the <logic:iterate> does not execute.

Hmm, the whole point of 'following the spec' as you put it and indeed
as I see it is to avoid portability problems ...

Translocatability ... that's a big 'Buzzword Bingo' word that I
remember from my training days, or maybe that's something else,

Anyway if moving to a different container might mean having to change
something (anything?) because Struts2 breaks if you don't, might mean
not using Struts2 ... which would be a shame because after years of
avoiding frameworks because ... well just because I like rolling my
own, I actually like some of the Struts2 features ... i18n is a breeze
for example (this whole idea of binding form input fields to buisness
component private attributes on the other hand is just plain NASTY).

Anyway, I will struggle on and no doubt come to a conclusion eventually

Thanks again for all the input on this

hi
i have successfully converted and deployed struts 2.0.11 application to
client
but still have some security questions because i have less knowledge of jaas
,realm or role based security

i have done authentication using query fire in database for user name and
password when user authenticated
i have stored his user name and user id and user type
(admin,executive,branch head) in session
problems

1. users can login from diff node or diff explorer n with same user name
,how to solve it

2. how can i apply realm or jaas in struts 2.0.11

please help me ,i am waiting for favorable reply

Here are my thoughts [based on my experience with Websphere but I hope they can be generalized):
1- Using session for users's authentication is not a very good idea esp if there is a chance that they may have multiple browser or tabs open at the sametime. there is a great chance of session mix-ups. However; if you are , for some reason or another, pressed to use http session, make sure that you use url rewriting instead of cookies for session tracking[ Websphere also allows a thrid way to use ssl ids for this purpose if you use ssl]. To do so you do not need to change your code, you need to change container settings.
2- Applying security using JASS or realm is a web-container setting not struts 2. You need to do two things:
    a) Enable the security of your container (server) to use a registery for authentication (LDAP,OS,...). Note that some servers like websphere allow you to extend its capability
        to use a custome registery (say database for this purpose)
    b) Change your web.xml and application.xml (add security constraints and roles and ...).
Once it is done. It does not matter u use struts 2 or struts 1 or anyother framework. At logging (first access) users get chanllenged.
In my case, to avoid using session for authentication, I am using an interceptor to retrieve user role and other information on each request. Note that once a user is logged in (assuming you use single signon),  users' credentials (login name) are cached by the server and at each request you can retrieve it using request.getRemoteUser(). So you can rid of session by paying a very slight overhead of retriving all necessary information at each request using an interceptor.

Hi All, I've a problem with textarea encoding. I use struts 2.0.11. I
put things like áí or ü into a text area, then I pass that value to
others pages (through session) and the the characters appear as "?".

I looked forums and all problems had a Db involved, not mine.

Any idea?

Thanks.

Juan Pablo.

Hi,

are the values still correct within your controller? And which Server
are you using?

I once had a similar problem, but I am not sure, if my solution can be
applied to your problem. In my case I tried to deliver strings with
umlauts as a GET-request-parameter to my controller, which failed. As
server I used Tomcat. I had to set the URIEncoding of Tomcat to UTF-8
what solved my problem. A comprehensive description of the problem (and
solution) can be found here:
http://tompson.wordpress.com/2007/01/29/encoding-filter-for-java-web-applications/

Hope that helps

I have no idea if the authors of the book Struts 2 in Action read this
list or if anyone that does
knows how to contact them but I have a question for them, or maybe
someone else knows the answer

Authors

On page 99, chapter 4 of your book you state.

"Every action in this package will
now have authentication with automatic routing back to the login page"

You then proceed to hard code the redirect.

How can the Login action be used for all actions in when you hard code the url

<action name="Login" class="manning.chapterFour.Login">
 <result type="redirect">
 /chapterFour/secure/AdminPortfolio.action
 </result>
 <result name="input">/chapterFour/Login.jsp</result>
</action>

How then for example would you use the Login action to secure the
AddImage action which is also a secure action

<action name="AddImage">
 <result>/chapterFour/ImageUploadForm.jsp</result>
</action>

Thank You

lyallex

Lyallex,

I'm not one of the authors, but I helped...

The example in the book doesn't work the way that typical container
managed authentication / authorization worked. A successful login
would be redirected to the AdminPortfolio (regardless of the original
request). If you are looking for more than this basic functionality,
take a look at Spring Security (formally, ACEGI). The configuration
appears daunting at first, but the boilerplate config example seems to
work for most apps.

Hi all,

I'm new to Struts2 and needed some help troubleshooting an error when I try
to use @CustomValidator.

Here's my setup:

I have the validators.xml file in /WEB-INF/:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
  "-//OpenSymphony Group//XWork Validator Config 1.0//EN"
  "http://www.opensymphony.com/xwork/xwork-validator-config-1.0.dtd">
<validators>
 <validator name="numericField"
class="xxx.validators.NumberFieldValidator"/>
</validators>

And then I have a class called NumberFieldValidator:
package xxx.validators;

import com.opensymphony.xwork2.validator.ValidationException;
import com.opensymphony.xwork2.validator.validators.FieldValidatorSupport;

public class NumberFieldValidator extends FieldValidatorSupport {
 // code
}

Then I have the following annotation on a model class:
@CustomValidator(type = "numericField", message = "Price must be a number")
public void setLowPrice(Double lowPrice) {
 this.lowPrice = lowPrice;
}

I am getting the following exception:
2008-07-11 11:22:44 INFO xwork2.validator.ActionValidatorManagerFactory -
Detected AnnotationActionValidatorManager, initializing it...
Jul 11, 2008 11:22:44 AM org.apache.catalina.core.StandardWrapperValve

java.lang.IllegalArgumentException: There is no validator class mapped to
the name numericField
 at
com.opensymphony.xwork2.validator.ValidatorFactory.lookupRegisteredValidatorType (ValidatorFactory.java:299)


Can anyone tell what I may be missing?

Thanks so much!

AFAIK this file needs to be on the classpath.

The validation documentation [1] points this out in the "Registering Validators" section, stating "The simplest way to do so is to add a file name validators.xml in the root of the classpath (/WEB-INF/classes) [...]"

Yes, that was the problem. Now I have another problem:

My interceptor stack is as follows:
          <interceptor-ref name="exception"/>
          <interceptor-ref name="alias"/>
          <interceptor-ref name="params"/>
          <interceptor-ref name="servletConfig"/>
          <interceptor-ref name="prepare"/>
          <interceptor-ref name="i18n"/>
          <interceptor-ref name="chain"/>
          <interceptor-ref name="debugging"/>
          <interceptor-ref name="profiling"/>
          <interceptor-ref name="scopedModelDriven"/>
          <interceptor-ref name="modelDriven"/>
          <interceptor-ref name="fileUpload"/>
          <interceptor-ref name="checkbox"/>
          <interceptor-ref name="staticParams"/>
          <interceptor-ref name="params">
           dojo\..*
          </interceptor-ref>
          <interceptor-ref name="conversionError"/>
          <interceptor-ref name="validation">
            _edit, input, save
          </interceptor-ref>
          <interceptor-ref name="workflow">
            _edit, save
          </interceptor-ref>

The parameters interceptor is fired before validation as suggested by the
struts 2 defaultStack. So actually before the @CustomValidation on the model
is able to happen, params fires with error:
2008-07-11 13:51:55 ERROR xwork2.interceptor.ParametersInterceptor -
ParametersInterceptor - [setParameters]: Unexpected Exception caught setting
'modelMap[344344].lowPrice' on 'class xxx.action.ItemAction: Error setting
expression 'modelMap[344344].lowPrice' with value
'[Ljava.lang.String;@(protected)'

Is there any way around this?

Thanks for your Answer, Lukasz.

I already know the PrepareInterceptor and it can be used for what I
would like to do. But I consider a special interceptor more convinient,
since I intend to use it for more than one pair of view and action.
(Using PrepareInterceptor would imply the need to add the code to every
single action.)

In my original post, i was wondering if there already is some kind of
"recipe"/"best practice"/"standard way" since I don't think that my wish
to put the actions together is very exotic.

But as nobody intervened I take this as a sign that my design is not
flawed :-))

See You!

You can also opt for sharing the prepare() code through inheritance,
meaning that you create a superclass action holding the prepare()
code, instead of coding a custom interceptor.

Hello Gabriel,

yes, I indeed took that into consideration, but if i am not wrong, there
are two drawbacks:

1: When I create my own base class, and would like to use the
prepare-method for something else, too, I need to overwrite the old
method and mustn't forget to call super.prepare() in my implementation.
IMO, this is a likely source of bugs.

2: I would have had to mess with the defaultStack anyway, since prepare
is located before some other important interceptors (e.g. i18n) so I
would have lost this functionality by taking an "early shortcut".

The Interceptor was done in 10mins and as far as i could test it, it
seems to work fine.

public class SubmitInterceptor implements Interceptor
{
 public static final String INPUT = "input";

 public void destroy() {}
 public void init() {}


 private String paramNames;
 
 public void setParamNames( String paramNames )
 {
   this.paramNames = paramNames;
 }  
 

 public String intercept( ActionInvocation ai ) throws Exception
 {
   Map params = ai.getInvocationContext().getParameters();

   String[] paramNames = this.paramNames.split( "," );
   
   for( String param : paramNames )
   {
     if( params.get( param.trim() ) != null )
       return ai.invoke();
   }
   
   return INPUT;
 }
}

I created a new interceptor stack for my webapp that is like
defaultStack, but with the SubmitInterceptor inserted right before
conversionError:

<interceptor-ref name="submit">
 <param name="paramNames">submit</param>
</interceptor-ref>

As for the view, i am currently setting the "submit" parameter (as
configured to be looked for above) for the Button:

<s:submit name="submit" label="OK" value="true" type="button" />

Comments and suggestions are welcome :-)

~Andreas

I'm replying to myself to say that I've told my customers to use anything but
Firefox 3 until Mozilla provides us with a patch that clears this problem.

Regards.

You don't say what the problem is, so it's hard to know how to help.

There's a known issue with Dojo [1] which may or may not be the issue you're facing-kinda hard to say. It's helpful to provide enough information to know where to start looking.

(Although it's wrong, it's close, and it provides links to relevant FF pages.)
