Re: Struts 2 - Repopulate controls when validation fails

[Lukasz Lenart]

Hi,

As I know, use of s:action tag should be avoided, the better option is
to use Preparable interface, you can use prepare() method
also.

Maybe it will be better if you implement your own validator for thoese
30 forms? I think it will be soft option then very compilcated

Put fron.txml file with whole path under src/main/resources, maven
only looks for classes from src/main/java and all other *.proeprties,
*.xml should be unser src/main/resources

Re: validation problem

[ManiKanta G]

Hi,

Even I've this problem... Here is my requirement

I've 3 fields. On successful validation of 1st field ONLY the 2nd field 
should be validated, and only with the successful validation of second, 
then only the 3rd field should be validated against some validation.


I did this by using field validator of type expression, like below...

   *
   
   
   Select 'Return to'
   
   

   
   
   
   
   Select company/dealer name
  
   


   
   
   
   
   Select drug
   
   

   *

With this, the second case working as it supposed. The second field will 
be validated ONLY when the first field is not empty (as in the second 
field expression, I m using */returnTo == null/* with short-circuit OR, 
and then the actual validation logic of second field).


But the validation logic of the third field (select box) is not working 
as is supposed to. When I print the expression value using *value="expression_of_the_third_field_."/>*, it is printing false, 
but the validation is being bypassed.


I've tried many ways. But non of 'em worked for me. Is any one got 
success with this type of validations.


I can implement custom validation using validate(), but I've around 30 
transactional forms with this type of requirements.


Am I doing any this wrong? Can anybody please guide me with this...


Thanks,
ManiKanta

The validation messages are placed in the form by the

form element tags. If you want to modify the output of
those tags you can modify or create a theme [1].

Using the "simple" theme will also remove

your usecase.

The  tag [2] will render any

Including XML files in maven war file

[Oren Livne]

Dear All,

I am building my first Struts 2 application. I'm using maven 2.0.9, jdk 
1.6.0_06 and jetty 6.1.10 to deploy inline in maven.

Here is my src/main/resources/struts.xml:



http://struts.apache.org/dtds/struts-2.0.dtd";>


   
   
  
   
  



It points to front.xml, which sits in 
src/main/java/net/ruready/web/front and looks like this:




http://struts.apache.org/dtds/struts-2.0.dtd";>


   

   
   
   /jsp/front/home.jsp
   
  
   



However, when I run "mvn jetty:run", Struts 2 doesn't find the action 
"front/home.action". I looked in the target directory as well as in the 
war file packaged with the command "mvn package", and I saw that 
front.xml was NOT included in WEB-INF/classes/net/ruready/web/front. How 
can I include it? I would like to use xml files in my source folders. I 
tried to tweak the maven war plugin but to no avail.


Could you kindly help me?
Thanks,
Oren

Struts 2 - Repopulate controls when validation fails

[bob fuller]

I'm following the "How do we repopulate controls when validation fails" FAQ 
located at...

http://struts.apache.org/2.x/docs/how-do-we-repopulate-controls-when-validation-fails.html

Of the two methods it suggests I am trying to use the 'action tag' method. 
Using the simple example from the FAQ works fine, but once I move beyond the 
simple and try to drop my "Languages" control inside the  tag of another action 
I have problems.

Here's my pseudo JSP (note MyAction)...









MyAction implements validateable and I am validating foo0 and foo1 inside the 
validate() method. Here's my validate() code...

public void validate() {
if (foo0 == null || foo0.length() == 0)
  addFieldError("foo0", "Foo0 is required");
else
  foo0 = foo0 + " VALIDATED";

if (foo1 == null || foo1.length() == 0)
  addFieldError("foo1", "Foo1 is required");
else
  foo1 = foo1 + " VALIDATED";   
}

The important thing to note about my validation code is that when the 
validation succeeds the data entered by the user is updated with the word 
"VALIDATED". This may seem like an odd thing to do, but it's part of the 
requirements of the project I'm working on.

Visiting http://localhost/MyAction/myAction_input.action works great. The page 
draws, foo0 is empty, the languages control has languages to choose from, foo1 
is empty, the submit button appears. Submitting the form is when I get into 
problems. Here are three submit paths and their results...

1. foo0 is empty, foo1 is empty. click submit. RESULT - foo0 is empty. foo1 is 
empty. SUCCESS!
2. foo0 = 'A', foo1 is empty. click submit. RESULT - page redraws. foo0 = 'A 
VALIDATED'. foo1 is empty. SUCCESS!
3. foo0 is empty, foo1 = 'A'. click submit. RESULT - page redraws. foo0 is 
empty. foo1 = 'A'. FAIL! - foo1 should say 'A VALIDATED'

For some reason MyAction.setFoo1() is being invoked *again* after I set foo1 to 
'A VALIDATED' in my validate() code. Why is that happening? I know it has 
something to do with the Languages control that appears before the foo1 text 
field, because when I remove the Languages control everything works as expected.

Anyone have any ideas about what the Languages control is doing that is causing 
my foo1 field to get reset to the original submit value? I'd really like to be 
able to use the 'action tags' approach for repopulating controls, but 'dropping 
wherever', as suggested in the FAQ (see link above), does not seem to be as 
easy as it sounds.

Thanks.

Is that actually rendering properly?!

I thought you had to add an index to the field name manually so it would be 
sent back as foo.bar[1], but perhaps I'm wrong.

Multi-row tabular forms

[Kleiderman, Matthew]

I'm trying create a form that maps to a collection of data objects, so
that a user can edit any property of any object, and submit the changes.
I'm using an s:iterator tag to draw each item in the collection as a row
in a table, and the xhtml template.  The table is getting drawn
properly, with data filled in from the collection -  but the Action
receiving the data always has the Collection set to null.  Here's a
stripped-down excerpt of what the .jsp looks like:


  
  
  

  
  

   
  


  


  

  
  

  



What am I doing wrong?

Re: Struts Validator Framework: problem with Custom Validator

[cacodemon79]

Now, server-side validation works!
I changed ActionErrors class with ActionMessages class into my java
validation method and into "validator-rules.xml".
The only problem is that
Resources.getActionMessage(request, va, field)
method in my custom validator class is deprecated and I don't know how to
replace it.
Can you give me any suggestions?


On the client-side, I have the same problem.
I see a javascript warning in browser: "twofields is not defined".
I have also tried to perform some changes to my files:
**
validator-rules.xml
**
 http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd";>
...
...
...




**
validation.xml
**
 http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd";>
...
...
...






minlength
8


mask
^[a-zA-Z0-9_.]*$


secondProperty
password2



So, my custom validation ("twofields") doesn't still work on client-side.
Can you help me?
I also tried to change the version of dtd validator...but nothing changed.
I can't understand where is the problem.

Hi Sarath,
where from this deploymentVersion is from (action, session)?
Such construction works for me in many places, so i would like to
replicate this problem.

Best greetings,

weird problem tag.

[sharath karnati]

Hi All,
 
    In .jsp file, I'm having following code which is using  tag.
 
    
 
    
    
   
    
   
   
  
     
   
 
 
 
   The  tag is showing properties values(projectNm,

of  'usercomment' and when it is having value 'All' still it is displaying 
'#usercomment.closingDate' value. I think that it is not validating  
condition correctly inside . If I move this condition outside of 
 it is working as expected.
 
   Please let me know, how to validate the properties which are not member of 
 value.

Struts 2 And Hibernate Problem

[cree]

Hello,
 
I recently have been working on a struts 2 + spring 2 + hibernate system and
have come across a problem that I never have when just working on a struts 2
system.  

I have two action classes, one that prepares the jsp and populates some
selects for the user to choose from, and another that takes and processes
the information.  When the first action is invoked the result will bring it
to the tiles (type="tiles") on the struts.xml file.  The second action will
take the form information and do a search, in this instance I am using
hibernate to access the db.

I would do the search and when I get the list of persistent values I would
chain (type="chain") to the first action class with the list of persistent
objects and would then return to the tiles and the jsp showing the values
that I found on the search.  

The problem I am having here is that because of the chain (or similarly a
redirect action), the list of persistent objects will re-appear if I went
off to some other action classes and came back.  What I mean by that is if I
had a list of 10 values that I searched for and displayed them,  if I went
to some other jsp/action class and came back to that same one the same exact
10 values are being populated.  

At that point when I would return to the original jsp the value stack should
have removed them completely, which it has.  There is no trace of the list
of persistent objects on the value stack as well as not being a cache
problem.  The situation arises when the chain occurs, I have worked with
just a struts 2 system for a year now and never had this problem.   I  know
this is the case because when I get rid of the chain and invoke the tiles
from the second action class the problem goes away.

I am not too sure why these values persist throughout the session and why
they re-appear even though they are not on value stack.  I have found a very
similar problem in which this person found that the problem occured during
an action redirect at 
http://www.nabble.com/Struts-2-%2B-Hibernate-question-td17527841.html
http://www.nabble.com/Struts-2-%2B-Hibernate-question-td17527841.html 

On a side note, just remembered, when I would want to populate the list 
after its already been populated (so the user will search once then decide
to search again) the values wouldnt change even after setting it to a new
list.  If I set that list to null first then changed it, the values would
change,  not sure if that makes much sense.

If anyone has an idea on what can be causing this I would greatly appretiate
your help.

Re: validation problem

[Dave Newton]

You either do conditional validations, implement custom validators, or as 
Lukasz suggested write your own validate() method. When validation is very 
complex the last may be the best options.

You can implement validate() or validate() and remember
to implement Validatable interface.

You're welcome to update the version of ognl you're using in your own

Theoretically this translates to a straight lookup for #object, then 
getA().getB().getC().getName()...
If A, B, and C are just accessors, it should be fast.  If they do much 
work to determine what to return, you're doing that work 2*N times 
(where N is the number of times through the loop) instead of just 
once...why would you put a long lookup like that in an iterator if it 
doesn't change with each iteration?

Re: Newbie: Call a servlet in another application and set attribute

[Nils-Helge Garli Hegvik]

I believe most servlet containers prevent sharing of session objects
between applications by default. But it probably can be configured to
be allowed (consult the documentation for your server to find out
how). A shared cache is also an option. But the easiest would be to
put them in the same application.

If they're actually two different applications, no, it wouldn't work. 

Unlike the other reply I had assumed they were in the same app, but apparently 
you meant what you said. Things don't work like that, on several ways, so 
you'll have to explore other options.

That's not passing the object, either; that's passing the string representation 
of the object. A bit different.

Re: Newbie: Call a servlet in another application and set attribute

[Marc Ende]

Hi Mustafa,

if I understand you correctly you're trying to pass an object in another
webapp. That's not a really struts-usecase. I think you're looking for 
a webservice or another kind of procedurecalls (like rmi).

I think you should look for axis, cxf or another project which are more
helpful for this kind of uses.

Newbie: Call a servlet in another application and set attribute

[Mustafa Cayci]

Hello,

I am fairly new to Struts.  I have two applications.  AppA is a Struts 
application and AppB is another application.  I have an Action class in AppA.  
Within execute() method, I am creating some objects.  I would like to call the 
servlet in AppB and somehow I want to pass these objects to the servlet in 
AppB. SO far I have this

public ActionForward execute(ActionMapping mapping, ActionForm form, 
 HttpServletRequest request, 
 HttpServletResponse response) throws Exception 
{
...
response.sendRedirect("/testsqlservlet/testsqlservlet?Object=" + 
object);
...

But this is a problem because even if I use SSL (i.e. https://) this redirect 
will be in cleartext and anybody can modify the "object".  What are my options? 
I am hope I explained myself clearly.

Thanks,

Mustafa

Re: Avoid having an action property called id

Hi Jonny,

I have id properties on actions all over my application.

I also have several actions that do a redirect to id. I think there's

the issue.

What exactly happens when it doesn't work?

Avoid having an action property called id

[Jonny Cavell]

This  http://www.vitarara.org/cms/struts_2_cookbook/post_and_redirect article
about post and redirect in struts 2  explains how to redirect to a
dynamically evaluated action.

However, if I use a param which references an action property called "id",
it doesn't work. 


  ${redirectActionName}
  /admin/holidays
  true
  ${id}


But when I changed the property (and its getter and setter) to be called
"aid", it works OK:

  .. as above...
  ..
  ${aid}



Also (possibly unrelated), again with a property called id on my action,
when I use the  tag, it automatically adds the current value of
the action's id to the URL even if I don't want it to. The docs don't
mention that this should happen (it's annoying).

It seems as if naming an action property id should be avoided...

namespace getting appended to servletPath

[Dwipin C]

Hi,
I have used a namespace "abc" for a particular set of action 
classes. The action class invocation happens with the namespace in the 
requested url, as expected.  However after the processing is done, the 
namespace is appended to the result jsp.

code snippet - 



http://struts.apache.org/dtds/struts-2.0.dtd";>





WEB-INF/jsp/Login.jsp
WEB-INF/jsp/Login.jsp

WEB-INF/jsp/ChangePassword.jsp


 


After processing, the servletPath is "/u/WEB-INF/jsp/Login.jsp" . Is this 
the expected behavior? I would prefer not changing my jsp location.
Any pointers would be of great help.

Thanks,
Dwipin Chandran.

customize the theme for every tag. 


Hope that helps.

Struts list

[Sonu S]

 HI,

I have to show list in my jsp page. I am using 

i am getting two lists from data base and it is in employee form bean: first
list is for employee no and second list is for name. i want to display
employee name in  and want to use employee no as VALUE in 
so list would have employee no as value and name will be displayed to user.

i am not sure how to do it with two lists as i have two different lists, one
list for emp no and one list for employee name. My form bean name is
employeeForm and list names are employeeNoList and employeeNameList. Please
help me... some code example would be a help for me. I am using struts 1.1

Thank you

Struts2 UI Tag HTML Compliance?

[albertooi]

Anyone aware if the Struts2 UI tags are HTML compliant? Which version of HTML
Specs?  E.g 4.x?  Need to ascertain which browser is supported if struts2 ui
tags are being used.

RE: use OGNL to automatically look in the session?

For anyone who's interested, #attr appears to check scopes in the
following order:

1. page / action *
2. request
3. value stack
4. session
5. application

* I used  to set one value at page scope and one at action scope,
and whichever was declared last was the one that #attr found first.





outputs page





outputs action

I'm not really sure what the action scope is. Perhaps it's only related
to . Either way, maybe this post will help someone searching

Hi,

In struts2 there is a provision for handling the error messages by field 
and action level.


If the message u want to display is not related to any particular field, 
then u can use ** tag at the top of ur page.


If the validation message is particular to a field, u can use 
** tag at the top of the page. This will displays all 
the field validation errors.
To display validation errors specific to a field, use * 
tag with *, like below


   *
   */fieldName/*
   *

Like this u can place individual field errors in ur custom layout in ur 
way, using tables, divs or something else.


When you explore the validation framework, what u see is more types of 
validation, which includes field validatiors & non-field validators.


Field validators are specific to a field, and thus adds a field error.
Non-field validators are NOT specific to any single field and thus the 
error message will be added as action level error (action error).


U can get more info regarding validations from Struts2 documentation.

Feel free to ask if u've need any clarification.

The validation messages are placed in the form by the S2 form element tags. If 
you want to modify the output of those tags you can modify or create a theme 
[1].

Using the "simple" theme will also remove the validation messages, but you'll 
lose other useful functionality--but that might not be an issue depending on 
your usecase.

The  tag [2] will render any error messages. A combination of 
either the simple theme or a modified theme plus the action error tag may do 
what you need.

[S2] autocompleter action extension

[Pierre Goupil]

Hello all,

I would like my S2 project to be mapped to .html actions, so I have
set this up :

- struts.action.extension=html in my struts.properties

-  in my
xwork-default.xml

-  in my
struts-default.xml.

Please note that for the two last ones, I have simply added the
property to the original file provided in the jar.

It works, in the sense that my actions respond and display my JSPs as
desired. BUT I can't figure out how to have the auto-completer tag to
work. If I use the .html extension, I get the following exception :

---
Could not find action or result

---

I think this is because Struts is looking for an .action action
extension : if I revert back to the default .action extension, it all
works. But as you can guess, I would like to be able to use whatever
extension I wish to.

A clue, anyone ?

Thanx in advance,

Pierre GOUPIL

Re: Slow performance with Struts2

[Paweł Wielgus]

Hi Joe,
sorry for the previus post, too fast fingers ;-)
Long time ago I had similiar problem in struts 1, when accesing lists
with logic:iterate it turned out that if i used  and this getMyList() method was not
really a getter but some logic that was building myList, logic:iterate
was accesing myList like getMyList().get(0), then getMyList().get(1)
and so on. Which obvoiusly kills the performance. I'm not using such
getters since then, but that may be the case in s2 also.

Best greetings,
Paweł Wielgus.

Re: Slow performance with Struts2

[yorlick kilroy]

Thanks for the performance-tuning links Dave. I Found a couple of
useful hints there.
Still... the "problem" seems to be the OGNL implementation in struts2.
It seems to me as if one should be VERY careful when using OGNL i.e.
make use of it very sparingly. in some of my jsps I descend fairly
deeply into my complex value objects consisting of maps and lists etc.
I dont have any benchmark results but it "feels" like the time taken
to render a jsp with lots of OGNL expressions increases exponentially
proportional to the depth of the used OGNL expression, for example:


 
 


Which isn't a performance problem when writing the above code in pure
java - only when done in struts2 OGNL

Can anyone confirm this?

Perhaps OGNL is only meant to be used for accessing only immediate
properties of an object and not to descend down into complex
tree-object-graphs.?
