Locale SEO permanent link URLs in Struts2

[Ignacio de Córdoba]

Hi there,
I have several working struts2 applications using i18n bu have an issue I
need to solve.
From the user perspective, the struts2 request_locale parameter approach is
perfect but as locale information is stored in session, urls visited by a
user (or robot) are not locale specific.
Is there a recommended approach in struts2 to do something like:

http://www.mysite.com/index.action  (english)
http://www.mysite.com/es/index.action 
http://www.mysite.com/fr/index.action 

Both should return the same code, changing only the locale. The main english
site should always return content in english locale, even if user has
visited the /es/index.action and so has changed the locale to spanish.

I've been thinking about extending the i18n interceptor to make struts work
this way and not storing locale in session, but maybe I'm missing something.

Of course, I also have the problem of mapping the /LANGUAGE/*.action
I wouldn't like to add mapping for every language I plan to use.

(I've also been thinking about using www.mysite.com for english,
es.mysite.com, fr.mysite.com, ... and making the custom incerceptor force
locale based on subdomain... I don't really like this option anyway)

thanks for any comments/ideas/directions,

Ignacio

Re: [Struts 2 + EJB 3] injection of EJBs into struts 2 actions

[Ignacio de Córdoba]

Which  appserver are you using?
I use JBoss for struts2 plugin. I hace to modifyit as it didn't support
JBoss 5 naming conventions (at least for me) and it only looked for
annotations in current class, so if you injected a Session Bean in a
super.execute() method in a parent class, it was not looked up.

Anyway, I am considering moving to EJB 3.1 and hope I can find a new way of
injecting new EJBs...

 Hi,
 I know that it is not possible to inject EJB in Struts 2 actions.
 The following annotation would not work :
 @EJB
 MyBeanLocal mybean;
  
 But how come ? Since a Struts action is a servlet and injection works in
 a servlet, injection should work.
  
 Thanks for enlightening me.

EJb 3.1 (dependency injection) and Struts2 actions ¿CDI/Weld needed?

[Ignacio de Córdoba]

Hi there,
I'd like to know if there is a recommended approach to deal with dependency
injection on new EJB 3.1 EJBs.
I am using now a modified version of JBoss Struts2 plugin with works great
but it really does nothing more than regular JNDI lookups on every action
request call.
I wonder if there is a new approach to getting EJB 3.1 session beans
(stateless to be precise) which is what mostly I have to deal with. I've
seen in the DEV forum that a plugin for CDI/Weld is coming (hopefully soon).
Should we have to wait for this plugin or there is a simple approach to just
inject new EJBs in struts2 actions? (@EJB... ? :-) )
Of course, I have already tested new GlassFish v3, even though I'll probably
be using new JBoss 6 (I have already tested it with my previous EJB3 Struts2
projects and works ok, so I'd like to start my new projects directly with
EJB 3.1)

Thanks for any directions.

s2: validation of checkbox a radio button

[Ignacio de Córdoba]

Hello,
I am trying to use client side validations through ...-validation.xml in
struts2
I have it working but only for text and file input fields. I need to
validate if a checkbox is checked. using required or requiredstring
validators always validates as the field as a value even if you don't
checkit. I guess the same happens with a group of radio buttons. (all with
the same field name). They have a value.

I have not found a OGNL expression that might work.

Anybody know how to solve this? I'd like to use simple client side
validation.

Thanks,
Ignacio

Localized key values in s:select

[Ignacio de Córdoba]

Hello, 
I wonder if it is possible to make s:select tag localize the content of
option elements. I am using: 

s:select labelposition=left key=category id=category
list=%{categories}  listKey=id listValue=name emptyOption=true/ 

I'd like attribute listValue=name property value if the objects iterated
not to be shown as is but to be used as a key to the language property
files... just like the key attribute value (category in this example) is
localized. 

¿Is it possible or I must pre-populate the list with already localized
strings? 

Thanks, 
Ignacio

Re: Using Struts2 JQuery drag drop

Hello,
I agree with your point of view, but sj: tags are a good start point to get
introduced to JQuery. I'll look anyway at remote divs the jQuery direct

 Hey Ignacio,
 
 I’m not a big fan of integrated ajax functionality. While it provides a
 simple solution at first when you need something a little more complex or
 customised it starts to show it’s limitations.
 
 Rather than using the sx;div tag why not just use a plain div and then use
 a
 jQuery ajax call, which can be triggered by your drag and drop event, to
 retrieve the content from the server side. I suspect that you want to pass
 your event coordinates to the server and display something appropriate.
 
 I don’t use S2 ajax plugin as I’ve been burnt by it too often. So,
 somebody
 else may be of more help on that front.

Re: Redirecting from mapping error exceptions

[Ignacio de Córdoba]

Hello,
2 years now from your question I wonder if you solved this. I'd like to do
exactly the same thing... redirecting any non existing action or error from
the user when entering the actin URL to the home page. (I mean, any 404
error)

At first I thought about using httpd error handling for this, but struts2
standard mapping now maps everything to the struts2 filter, even static
content, so now I get the There is no Action... error for any non existing
URL in my site. I guess that means Struts has to handle it or to change the
configuration and make struts2 handle only .action calls (which is complex
as there are a lot of .js, images, etc. now in struts jars which would have
to be uncompressed)

localization properties files working in WEB-INF/classes and not in WEB-INF/lib/NAME.jar

Hi there,
I am facing a strange problem. My properties files work fine when I put them

but struts2 actions and tags (s:text) won't find them if I include them in

/WEB-INF/lib/myActions.jar

s:checkbox inside a s:iterator and values in a Integer[]

[Ignacio de Córdoba]

Hello,
I've browsed nabble, google, ... but can't find a simple example on how to
do something very simple.

I need to iterate through, let's say, a picture category list, showing each
category as a s:checkbox. The picture belongs to some of these categories
(and user can changed that, or course, thanks to the checkboxes), so some of
the checkboxes must be pre-checked. Which of them are checked is shown in a
Integer[] (could be String[] if necesary, no problem). I guessed the right
way to do it is using a String or Integer array as checked values will be
sent to the struts2 action through that same property.
Is it that difficult to use s:checkbox for this? I know how to do it using
s:checkboxlist but can't here as I need special format in the iteration.

For some reason the following:
s:iterator value=categoryTree
s:checkbox labelposition=right name=categoryId fieldValue=%{id}
label=%{name}/
/s:iterator

(categoryId is a Integer[] having which id values should be checked but all
checkboxes appear as checked)

For some reason I've found more people with this same problem but they got
no answers. Thanks for any example or ideas if I must change the way
pre-checked data is got from the action.

Re: s:checkbox inside a s:iterator and values in a Integer[]

[Ignacio de Córdoba]

Thanks a lot for reply. It works OK that way. I had to make a getter for the
Category objects as a List and maintain the setter for the categoryId
Integer array. It would be great if s:checkbox could also check when to
pre-check the checkbox in the same way as s:checkboxlist does (I think I
used s:checkboxlist getting checked fields from the Integer[] id getter. It
makes sense to use the same property to get checkbox status and to set
checkbox status)

Anyway, thanks a lot for your example.

emptyoption with s:select and Integer values

[Ignacio de Córdoba]

Hello,
I need to use s:select with emptyoption=true attribute. it works OK with
Strings but can't make it work with Integers. As empty option generates an
empty string option parameter value, Struts2 seems unable to convert it to a
null value if setter method in the Action is Integer. I get:

ognl.MethodFailedException: Method setPlaceId failed for object
com.servengine.pim.eventadminacti...@336f9bc6
[java.lang.NoSuchMethodException: setPlaceId([Ljava.lang.String;)]

(An array of Strings? I am just selecting the empty value... anyway...)

Any ideas or workarrounds. I would like to avoid moving all this type of
properties to String.

Thanks,

Re: Integer s:checkbox sends false value to action setter

[Ignacio de Córdoba]

Hi,
I've seen this has not been solved or replied here. Could anybody give me
any directions on how to post a JIRA issue for this?
I've seen https://issues.apache.org/struts/secure/BrowseProject.jspa but
can't get to the area for posting new issues/bugs.

Thanks,

RE: Integer s:checkbox sends false value to action setter

[Ignacio de Córdoba]

OK, I understand but I am using checkboxes for the typical remove entries in
this forum action. The value are integesr (primary keys of the entries) and
so the setter in the action is:

public void setRemoveEntry(Integer[] id)
{
}

When i check no checkboxes in the form, I get the exception, as struts is
sending false (string) to a Integer array property. I'll try the
interceptor you point. Thanks,
Ignacio

 I do not believe this is a bug. Setting the value to false when unchecked
 is most useful for a lot of cases. I hated when in S1 you had to reset all
 your checkboxes in code in order to get unchecked values that were
 previously checked when the page loaded.
 
 Furthermore, there are struts 2 books out there that explain how this
 could work. Did you try this:
 
 interceptor-ref name=completeDefault
   -1
 /interceptor-ref

sx:textarea border (and label...)

[Ignacio de Córdoba]

Hi,
I am using sx:textarea in several pages and the HTML visutal text editor
renders and works ok. I'd just like to make it have a simple border, like
every input type text or type textarea has. I'd like to do this directly and
avoid enclosing sx:textarea in some type of div class=border to make it
look have a real border.
Any ideas on how to do this?

Thanks,
Ignacio

P.D.: By the way... how to make label and labelposition work for
sx:textarea?

How to define a String array in FreeMarker

[Ignacio de Córdoba]

Hi there,
i am using FreeMarker to generate HTML content for mails in my application
(not for the web presentation; I use JSP for that).
I so use FreeMarker directly, not integrated to struts.

My problem is localizing messages with parameters. I am invoking the
freemaker template passing the action (it self) as an object. Then I get the
text invoking struts2 ActionSupport getText method:

This works ok when there are no parameters ( ${action.getText(hello)} )

but suppose portalid is a string variable and I try:

${action.getText(pleaseConfirmYouWantToChangeYourPassword,portalid)}

The problem is that portalid variable should be an array of strings, not a
string. I am new to freemarker and don't know if it is possible to define a
string array inside the template. Something equivalent to java:

String[] portalidArray = new String[]{portalid};

Is it possible? How?

Thanks for any help,
Ignacio

Removing the align=right from s:submit tag

[Ignacio de Córdoba]

Hi there,
i am using css_xhtml them and renders all form elements quite ok but it
inserts a align=right in the div enclosing every submit button.
Is there anyway to remove that right alignment? I guess all this should be a
matter of css and not an alignment in the HTML code. Don't know if it is a
bug of the theme or the desired code rendered.
I've searched here but found no info on how to extend or modify a builtin
them in struts2.

thanks for any help,
Ignacio

Re: Removing the align=right from s:submit tag

[Ignacio de Córdoba]

Thanks for your reply... ... my tag:

s:submit key='store' cssClass=myClass/

renders:

div align=rightid=wwctrl_Category_store_action_storeinput
type=submit id=Category_store_action_store name=store value=Store
class=myClass//div

As you see, div enclosing the input tag has no class. Just align and
id fields. To override that align i'll have to add a entry for every
s:submit in my application. I don't know how to add a class to that div.
Anyway, that would make me change all s:submits.

¿ Is it that complex to override s:submit and make it just render:
div id=wwctrl_Category_store_action_storeinput type=submit
id=Category_store_action_store name=store value=Store
class=myClass//div
?

Maybe I'm missing something... i'll try wrapping css_xhtml them into a new
theme as explained in the docs. Thanks for any other ideas on this...

Re: Removing the align=right from s:submit tag

Thanks Dave,
I did that (myClass) but the class is only added to the input / tag, not
to the div enclosing it, which is the one that has that magnificent align
parameter. I'm on my way extending css_xhtml them to try to solve this. I'll

Re: Removing the align=right from s:submit tag

[Ignacio de Córdoba]

Hi again Dave,
I am using Struts 2.1.2 (I believe it is last public version).

I'll try to make that patch. Got a private message from other user with
directions about which classes to check (SubmitTag, AbstractUITag and
AbstractClosingTag)... anyway, I've never made such a patch so I'm sure I'll
take me a lot of time. I'll try anyway but also post here any solutions I've
found.

Thanks,
Ignacio

 Oh, right. Which version of S2 are you using? There were at least a 
 couple of issues with non-CSS-ish behavior in the CSS theme that may 
 have been addressed at some point (like br/ tags etc.)
 
 If it hasn't been fixed already consider creating a patch against the 
 current S2 trunk to clean up any remaining issues.

Re: Removing the align=right from s:submit tag

[Ignacio de Córdoba]

Hi there,
Maybe this helps someone else... I just solved my problem by unpacking
struts2-core-2.1.6.jar and placing submit.ftl file in webapp dir
/WEB-INF/classes/template/... commenting the following:

#--if parameters.align??
align=${parameters.align?html}#t/
/#if--

(Lines 20-30)

I noted that these didn't work for sx:submit, which I also use a lot; I had
to unpack struts2-dojo-plugin-2.1.6.jar (which contains ajax template) and
do the same (/template/ajax/...) In this case, align parameter appears
twice.

I'll figure out how to do the patch. I guess that at least for css_xhtml
theme, no align code should ever appear in HTML code.

Ignacio

RE: Removing the align=right from s:submit tag

[Ignacio de Córdoba]

Hi again,
I have successfully extended css_xhtml theme but I am having a problem form
sx:submit.
I specify struts.ui.theme=servengine in struts.properties and the new theme
works OK (servengine y the name of my new theme)

My problem is... sx:submit still uses ajax theme (I had to replace
submit:ftl also for this) Obviously I have to also extend ajax theme
(servengine_ajax) but... how do I specify the framework to use that new
theme for sx tags in struts.properties?

thanks,
Ignacio

Re: Struts and EJB 3

Hi, I use JDeveloper but I just ad jars in the standard tiles and struts
distributions without any changes. Anyway, what is your exception when
trying to start the web-app? Maybe you should start there. Look at the
missing class and ensure it is in a jar inside WEB-INF/lib. Also, how do you
deploy EJBs? I use a different .ear file so to isolate layers (model -
view)

Invoking a method in the Action from a FreeMarker template

[Ignacio de Córdoba]

Hi there,
I am trying to invoke a method in a struts2 action from a FreeMarker
template. To do this, I put the action as an object named action and
then I reference it, for example, as:

#list action.sortedFields as field

(Sorted fields is a method: getSortedFields())

this works OK, but I cannot invoke methods with parameters... not just
getters. For example I try:

${action.getTheFieldEntry(7)}

I get

freemarker.core.InvalidReferenceException: Expression
action.getTheFieldEntry(7) is undefined on line 6, column 57 in
formprocessor/formEntryMail.ftl.

(getTheFieldEntry has the following signature:
public String getTheFieldEntry(int fieldId){...}
)

Is it only possible to invoke object getters and setters? I've read
Fremarker docs and regular methods can be invoked.

Thanks for any help,
Ignacio

again... dynamic s:tree

[Ignacio de Córdoba]

Hi there,
I am trying to build a dynamic tree in my application. I used to do it with
struts1, nested tags and making it recurse by including a JSP file
recursively. I don't find the nested: tags in struts2 and after searching
nabble it seems that s:tree tag is not finished to be able to obtain a
dynamic tree (coming from a persisted object structure... I mean... like a
file directory structure for example).
Anybody can give any directions on how to build this type of structure in
struts2? As I see it I maybe I have to code HTML in the action (!) to
obtain it. I'd like not to do that...
(I dont need the tree to expand and collapse... I just need to draw it)

thanks for any help.

Making labelposition=left default

[Ignacio de Córdoba]

Hi there,
I asked this some time ago but after doing, again, some search here and
googling I still need find a way  to make my forms s:textfield have a
default labelposition=left attribute. I am using css_html theme... 
I have done a find/replace to make all my s:textfield have that property in
the html but maybe it can be done a simpler way in a properties file or
extending the theme...

thanks for any help,

sx:textarea and label

[Ignacio de Córdoba]

Hi there,
I have just replaced s:textarea with sx:textarea to get the HTML editor. It
works OK but now I don't see the labels for these textarea fields:

sx:textarea key=headline name=headline/

¿Anybody knows if that is the suppoused behaviour and I must add label
tags my self?

Re: OGNL problem in s:checkbox

[Ignacio de Córdoba]

Hi,
I fond the answer to my problem. Maybe it helps anyone here...

if service is the var from a s:iterator doing

%{serviceNames.contains(service)}

will not work but

%{serviceNames.contains(#attr.service)}

will work.

I don't know how. Must be related of how objects are set into OGNL

OGNL problem in s:checkbox

[Ignacio de Córdoba]

Hi there,
I am trying to activate some checkboxes if a certain condition is matched:

s:checkbox name=activeServices
value=%{userSession.portal.serviceNames.contains(service)}
fieldValue=%{service}/

service is a String var which contains my site service names. I get it
iterating over a collection. checkbox should be checked when serviceNames
contains the String in service var.

It works OK if I replace service var with a string:
%{userSession.portal.serviceNames.contains('mail')}
but using avar won't work. Any idea why I can't replace mail literal with
a var there?

Thanks for any help,
Ignacio

Re: FreeMarker error when trying to use AJAX Theme

[Ignacio de Córdoba]

thanks for your reply...
If I understood you, then css theme actionerror.ftl or at least simple theme
actionerror.ftl should be picked and rendered. Can you think of the reason
for these templates not shown? (If seen more people with this same problem
asked in forums but now answer to them)

thanks,
Ignacio

 i don't have a solution to your actual problem, but the issue you
 note in the sentence above is actually not an issue.  if a template
 doesn't explicitly exist for a theme, the theme's parent is checked, and
 so on.  so for actionerror.ftl, it'd first look for it within ajax.  if
 not found there, it'll look in the xhtml theme.  if it's not there
 either, it'll look in the simple theme.
 
 of course, if it's not there, either, then you're well and truly
 screwed... ;)

Integer s:checkbox sends false value to action setter

[Ignacio de Córdoba]

Hi there,
I am trying to start using struts2 checkboxes via s:checkbox tag:

s:checkbox name=removeExtraUserdataFieldId theme=simple
fieldValue=%{id}/

This renders:

input type=checkbox name=removeExtraUserdataFieldId value=3
id=index_storePreferences_action_removeExtraUserdataFieldId/
input type=hidden
id=__checkbox_index_storePreferences_action_removeExtraUserdataFieldId
name=__checkbox_removeExtraUserdataFieldId value=3 /

I was getting an error which sais String setter was required, and not a
Integer setter. I didn't understand why as values where ints but now I've
changed setter in the action to:
public void setRemoveExtraUserdataFieldId(String[]
removeExtraUserdataFieldId){}

I get a conversion error as when no checkbox are checked, that setter is
invoked with a false string argument. (If I check one of the checkboxes,
no problem).
Why is that false string used. In old Struts1 no setter was invoked in the
ActionForm if no checkbox was checked.

thanks for any ideas,
Ignacio

FreeMarker error when trying to use AJAX Theme

Hi there,
i am trying to use AJAX theme to use sx:datetimepicker tag but whether or
not I use that tag I am getting the following error only by adding the ajax
header:

sx:head debug=true cache=false compressed=false /

I thought it was caused by the date picker, but it happens on every page (I
use Tiles2 with struts2.1)

Thanks for any help/directions:

How to render a JSP/Struts2 action to send it (mail, ...)

[Ignacio de Córdoba]

Hi there,
I had a working solution that was fine for struts1 and doesn't work with
struts2.
The scenario is evey time the application needs to send a mail from an
action (for example, when a user signs up, the system sends him a welcome
mail)

My solution got the JSP the following way:

public String getResourceAsString(String path) throws ServletException,
IOException
{
HttpServletRequest request =
org.apache.struts2.ServletActionContext.getRequest();
HttpServletResponse response = 
ServletActionContext.getResponse();
try
{
ByteArrayOutputStream out = new ByteArrayOutputStream();
RequestDispatcher dispatcher = 
request.getRequestDispatcher(path);
RedirectingServletResponse dummyResponse = new
RedirectingServletResponse(response, out);
dispatcher.include(request, dummyResponse);
return out.toString();
} catch (NullPointerException e)
{
return pNo such template:  + path + /p;
}
}
 
(RedirectingServletResponse class just extends HttpServletResponseWrapper
and captures output to a ByteArrayOutputStream)


The JSP needs a small scriptlet at its end:
% out.flush(); %

Without it, the mail is sent blank as the JSP is not rendered to HTML/text
as the request has not ended (I use the current thread request because: 1) I
don't know how to create a brand new request/response 2) This way I can use
all request parameters, attributes... in the mail sent and so not use just
plain HTML but real JSP.

The problem now is that struts2 shows the following exception:

java.io.IOException: Stream closed

   
org.apache.jasper.runtime.JspWriterImpl.ensureOpen(JspWriterImpl.java:204)
   
org.apache.jasper.runtime.JspWriterImpl.flushBuffer(JspWriterImpl.java:115)

Any ideas on this... or better... any directions on how can I instanciate a
fake response not based on current struts2 Action ServletResponse object
(and so flush() or close() will not affect it).

Thanks,
Ignacio

hi again,
thanks for your reply. I've never used FreeMaker or Velocity. I use
Tiles2... can you figure out if your solution can be solved with Tiles2. I
wouldn't like to get into those, I'm sure great, technologies only for this.

Thanks,

 For example, for FreeMarker (which will be in the classpath already),
 I use this:
 
 public static void process(ServletContext context, String template,
 MapString, Object values, Writer writer) throws IOException,
 TemplateException {
 Configuration cfg = new Configuration();
 cfg.setDirectoryForTemplateLoading(new
 File(context.getRealPath(/templates)));
 cfg.setObjectWrapper(new DefaultObjectWrapper());
 
 BeansWrapper wrapper = BeansWrapper.getDefaultInstance();
 TemplateHashModel staticModels = wrapper.getStaticModels();
 Template temp = cfg.getTemplate(template);
 temp.process(values, writer);
 writer.flush();
 }
 
 //also JSP has not way to deal with empty spaces and such

Re: How to render a JSP/Struts2 action to send it (mail, ...)

[Ignacio de Córdoba]

OK. Thanks for the advice. I tried to use Tiles2 because my user interface is
used with Tiles2. If I get a Tile for the email, the email received has the
same lookfeel as the web pages. And I can re-use JSP/JSTL/OGNL parts.

I'll give FreeMarker a try... just a question... in the code you sent... the
String template argument is just the file name of the Freemarket content
(mail.ftl) file?

Thanks,
Ignacio

 For example, for FreeMarker (which will be in the classpath already),
 I use this:

 public static void process(ServletContext context, String template,
 MapString, Object values, Writer writer) throws IOException,
 TemplateException {
 Configuration cfg = new Configuration();
 cfg.setDirectoryForTemplateLoading(new
 File(context.getRealPath(/templates)));
 cfg.setObjectWrapper(new DefaultObjectWrapper());

 BeansWrapper wrapper = BeansWrapper.getDefaultInstance();
 TemplateHashModel staticModels = wrapper.getStaticModels();
 Template temp = cfg.getTemplate(template);
 temp.process(values, writer);
 writer.flush();
 }

 //also JSP has not way to deal with empty spaces and such

 Hi there,
 I had a working solution that was fine for struts1 and doesn't work
 with
 struts2.
 The scenario is evey time the application needs to send a mail from an
 action (for example, when a user signs up, the system sends him a
 welcome
 mail)

 My solution got the JSP the following way:

public String getResourceAsString(String path) throws
 ServletException,
 IOException
{
HttpServletRequest request =
 org.apache.struts2.ServletActionContext.getRequest();
HttpServletResponse response =
 ServletActionContext.getResponse();
try
{
ByteArrayOutputStream out = new
 ByteArrayOutputStream();
RequestDispatcher dispatcher =
 request.getRequestDispatcher(path);
RedirectingServletResponse dummyResponse = new
 RedirectingServletResponse(response, out);
dispatcher.include(request, dummyResponse);
return out.toString();
} catch (NullPointerException e)
{
return pNo such template:  + path + /p;
}
}

 (RedirectingServletResponse class just extends
 HttpServletResponseWrapper
 and captures output to a ByteArrayOutputStream)


 The JSP needs a small scriptlet at its end:
 % out.flush(); %

 Without it, the mail is sent blank as the JSP is not rendered to
 HTML/text
 as the request has not ended (I use the current thread request because:
 1) I
 don't know how to create a brand new request/response 2) This way I can
 use
 all request parameters, attributes... in the mail sent and so not use
 just
 plain HTML but real JSP.

 The problem now is that struts2 shows the following exception:

 java.io.IOException: Stream closed


 org.apache.jasper.runtime.JspWriterImpl.ensureOpen(JspWriterImpl.java:204)

 org.apache.jasper.runtime.JspWriterImpl.flushBuffer(JspWriterImpl.java:115)

Re: Text link to submit a form ¿struts2 way?

[Ignacio de Córdoba]

Are you really sure that s:a generates a a.../ tag that submits the form???
I just get a regular link pointing to a regular URL, no form or form data
anywhere.
By the way, formId property is not a property for s:a tag, at least not in
docs and TagLibDocs.

 actually, the form doesn't need to use struts tags, there... could
 just be a plain html form.  just so long as the form tag has the id
 attribute set, and that id is used in the s:a tag, it'll work.

I love submit buttons but in this design I must use text as submit buttons.

OK... I know I must use javascript. My question really was about if struts2
s:a or sx:a tags had an option to generate that javascript submit text link,
in a similar way as s:submit generates the input type=submit. I guest not.
:-(
Maybe it is an interesting option for a future release.

Indexed properties in forms

[Ignacio de Córdoba]

Hi there,
I am trying to migrate a form population module from struts1 to struts2 and
I am not sure if struts2 supports indexed/mapped value properties.

After reading OGNL docs I see that indexed properties are supported both
with ints and objects. I guess they refer just to red de properties, not
to set them in the action... so I am trying:

s:textfield label=%{name} name='fieldEntry[%{id}]' / Where id is an
integer.

My action has the method:
public void setFieldEntry(String fieldId, String value){}
(I've tried fieldID with int, Integer and String)
(Also I've tried String value and String[] value just in case it expects an
array of strings)

When I submit the form I get:

2009-02-11 02:14:49,195 WARN  [com.opensymphony.xwork2.ognl.OgnlValueStack]

How to generate a URL with s:url encoded in UTF-8

[Ignacio de Córdoba]

Hi there,
I am trying to generate a URL with s:url and s:param so that parameters are
encoded in URL. Special characters are not processed ok. (The struts action
works fine as I have posted that same URL data with a form encoded in UTF-8
and they are decoded fine in my java code)
I've tried doing s:params:property ... escape=true/s:param but no
luck. Chars are escaped but not encoded UTF-8.
Any ideas if this is possible?

Thanks,

s:iterator ¿begin - end?

[Ignacio de Córdoba]

Hi there,
I've checked struts2 docs and this forum and have found no inside syntax for
s:iterator tag to do:
c:forEach var='' value='${}' being='1' end='4'/

Examples in docs just show how to count from 1 to 5 ¿? I'd like to avoid
counting and using indexed property to access an iterator. The last example
in docs doesnt seem to work if I replace this with the property/objet I
want to iterate.

I am sure struts2 team has thought of a way to do some partial iterator (I
can also do the full iterator and do a s:if to show only 5 values using
status.index, but doesn't seem a nice solution.

Thanks,
Ignacio

Is possible to set encoding=false as default?

Hi there,
I am having a problem with encoding and s:property... (and other tags). As
default it encodes non ASCII chars and I get:

categor#xED;a y tecnolog#xED;a

s:property in my project?

Re: s:iterator ¿begin - end?

[Ignacio de Córdoba]

Hi,
thanks for your reply.
Well... I have to iterate through a collection accesible in a struts2
Action. I can make that object visible to the page/request scope and then
access it from JSTL c:forEach; in fact I am doing that for dynamic images
as strugs2 has no IMG tag to use OGNL directly. Very painful when someone is
used to access the object from the tag itself. Moreover... I am really
trying to forget about EL and JSTL. I really don't find my self confortable
using 3 different expression languages / tag libs in my pages. I didn't have
to (in struts1) but maybe I have to accept that idea now.
Moreover, EL is obsolete when compared to OGNL (oh god... when I discovered
I could do #{people.size()} I just didn't believe it!!! Direct access to
methods. JSTL hasn't been improved for 4 (5?) years! Method access,
valuestack... and I am new to OGNL. Don't know 50% of its power!

More situations: I made my HTML designers learn JSTL. Now I have to make
them learn OGNL and I am sure they'll have problems with both things mixed.
Of course, I'd like new people in the company thinking about the
presentation layer just to handle one thing.

Why doesn't OGNL team focus on making it possible to forget about JSTL+EL
and just use OGNL for every thing? It nearly does and just because a
couple of minor glitches we can't. (Another example... s:a tag doesn't have
target attribute. I have then to use HTML   tag directly, what forces me
to transfer the href data in the Action to an object in the page scope and
use EL where. Painful for something that should be straightforward.

Well... sorry for the long text. Please don't take me wrong. Just love
struts2 and would love to forget about old technnologies. I wish I had time
and knowledge to help on all this. Now I just can't.

How to change locale inside an Action method

[Ignacio de Córdoba]

Hi there,
I've been searching through struts2 docs and old threads here but I've found
no way of changing current locale from inside an action. I know I can pass a
parameter in the request, and maybe other ways to change it... but I am
looking for a method that allows me to change current locale from inside the
action.
I used to do setLocale(...) but that method doesn't seem to be implemented
in ActionSupport.

Re: How to change locale inside an Action method

[Ignacio de Córdoba]

Thanks for your reply,
I had read the i18n docs you refer but still find no info about changing the
session locale inside an Action.
Anyway, after reading the source of the Interceptor, I understand that
doing:

session.put(i18nInterceptor.DEFAULT_SESSION_ATTRIBUTE,myNewLocale);

in my Action should change the locale in the session. Do you believe that's
right and nothing extra needs to be done?

OK. Thanks again... after reading some other docs I'll be doing:

ActionContext.getContext().setLocale(locale);
session.put(com.opensymphony.xwork2.interceptor.I18nInterceptor.DEFAULT_SESSION_ATTRIBUTE,locale);
  
session.put(Config.FMT_LOCALE, locale); //Also for JSTL, not only Struts.
session.put(javax.servlet.jsp.jstl.fmt.locale.session, locale);//Just to
be really sure

(I hope this will really change locale)

Re: How to change locale inside an Action method

[Ignacio de Córdoba]

Great attitude yours :-)

I'll explain my (simplified) case... I am migrating a struts1 content
manager to struts2; maybe I still stick to struts1 concepts but... imagine
there are several articles in the users screen. They might be written in
different languages; an article language is set in a property in the
ArticleEJB, so the view layer doesn't know which language they are written.
When the user clicks in an article, if current locale is not the one in that
article, I want my action to change the session locale. I might not want to
change that locale depending on other article properties.
I know this can be done by getting the locale from the article and adding it
as a request_locale parameter in the link but I will not always want to
change locale, only for some articles. I want that decision to be taken in
that Action, not in the view JSP layer or in previous Action.

I am already using the request_locale i18n interceptor aproach in other
circumstances, when I know in advance I want to change the locale. It's
perfect for that but maybe not for the case exposed.

[Ignacio de Córdoba]

Oh yes, I have no problem with EJB3 init parameters. The only thing I am
really missing is where to put struts2 actions init paramers.

Struts2 + Guice JNDI names as a parameter

[Ignacio de Córdoba]

Hi there,
I am trying to use Guice to take care of the injection of Local Stateless
Session Beans (I use Jboss 4).
My problem is that all solutions I've found using guice involve hard coding
the application ear name. (JBoss sets JNDI of EJBs depending on the ear file
name).
I've read Struts2 Guice plugin docs and examples but I've found no way to
pass the application name as a parameter (getting the ServletContext name
should be enough) into com.google.inject.Module.

Anybody knows if I can use any parameters in struts.xml? Now I am using the
proposed, struts.objectFactory and guice.module constants.

P.D: I've extended struts2ejb3-jboss-plugin to solve this with interceptor
aproach if anybody is interested.

thanks for any ideas,
Ignacio

Best global parameter aproach for struts2

[Ignacio de Córdoba]

Hi there,
after starting some serious migration from struts to struts2 I am wondering
is there is any best practices for global application parameters.
I used to store this parameters in web.xml, but as struts2 finds important
not to be tied to the http thing (I read it very often in docs... about
unit testing, etc.) I find myself with problems every time I want to get a
web.xml init parameter.
In actions it is not that difficult, but it is in interceptors, as there is
no way to get the ServletContext as they have no init method getting it as a
parameter. (I am now lazy loading that parameter at first Action invocation
to the interceptor)
I wonder if there is another aproach to set init parameters and forget about
web.xml... I need some init parameters easily readable from both actions and
interceptors... struts.xml, struts.properties, ...

Thanks for any ideas,
Ignacio

Re: Best global parameter aproach for struts2

[Ignacio de Córdoba]

Thanks for your reply,
I have lots of code developed for struts1+tiles+EJB3 (Jboss). I am migrating
struts-tiles to struts2 + tiles2. I have too much EJB3 code and I don't have
a clear picture of where I can fit Spring there. I have so much time to
invest just to move to struts2... and absolutely I don't want to touch a
line of code in the bussiness layer. I can't afford it.

Accesing Cookies from a custom interceptor

[Ignacio de Córdoba]

Hi there,
I am writing a custom authentication and authorization interceptor and need
access to cookies. I've checked in Struts2 and other docs both ways of
getting access to cookies. I can't  use CookieInterceptor or CookiesAware
interface as I need cookies in the interceptor, not in an action, so the
only way I've found is using the static method at
org.apache.struts2.ServletActionContext.getRequest() to get the request and
getting cookies from it.
I'd like to know if there is another path to get cookies in my interceptor.
I've been developing on struts for a couple of years but I'm pretty newbie
to struts2.

Thanks for any help/directions,
Ignacio

Injecting in Interceptors

[Ignacio de Córdoba]

Hi there,
I am developing a Authorization interceptor and need to perform a JNDI
lookup to get some Stateless EJBs from JBoss.

My problem is that this interceptor init() method gets no parameters. I need
to get at least the ServletContext of the web application to specify the
main JNDI lookup name. (EJBs might be deployed in different JNDIs dirs
depending on which application I deploy them).

Anybody has an idea on how can I get info about ServletContext in the init()
method of an interceptor? I'd like to lookup EJBs there and not lookup them
for every request (I know I can get the info I need from ActionInvocation
object that every intercept() gets)

I'm using Struts 2.1

Thanks for any ideas,
Ignacio

Re: Injecting in Interceptors

[Ignacio de Córdoba]

Hi Musachy and thanks for your reply but that static invocation in that class
is not working if called from an interceptor or, at least, from the init()
method of the interceptor.

Probably this is due to the way it gets the ServletContext. Probably it
first gets the request or the session, and uses current thread for that. As
in the init() method there is no Action (remember Interceptors are not
binded to an action or request, but instanciated only once at the web
application deployment) there is no request/response/session, and so I
returns null. No ServletContext. :-(

Any other ideas? :-)

Thanks,
Ignacio

Re: Injecting in Interceptors

[Ignacio de Córdoba]

Thanks for your reply Dave,
I'll have to solve it that way... but I wanted to use the init() method and
so avoid the if() checking for the EJBS existance... 
Without any info about the environment I don't really get how that method is
useful for anything.

Thanks,
Ignacio

 You don't need to get JNDI resources on every request--use the lazy 
 initialization pattern and only get it the first time. Since 
 interceptors aren't re-instantiated this should work fine.

Re: Injecting in Interceptors

[Ignacio de Córdoba]

Hi,
I saw that plugin but it solves the application name subdir to be supplied
in the JNDI lookup with a parameter in the Annotation, which makes it code
dependant. I need to get that data from the ServletContext (application
name) or at least a webapp init parameter.
As I see it, the lazy load aproach seems the best for the moment.

 Did you try to use that plugin [1], you can ever base on it, build

Loosing content type encoding in bean:include

[Ignacio de Córdoba]

Hi there,
I am having a problem when trying to include a page using bean:include. I
loose the encoding even the included page has the right @page encoding ...
attributes.
Is this a bug or I am doing something wrong?
I am using struts 1.3
I've tried to use othre include options, but bean:include is the one that
doesn't make struts change module in the request (I use different modules
but wich jsp:include or c:import including an action from other module makes
the current module be changed and so html:form's don't work.

Thanks for any help... any of both issues would solve my problem as
jsp:include or c:import handle correctly the page encoding.
