Re: How to compare string reference variables using ognl?
In OGNL, the == test will call the equals method,
so, I believe the expression #selectedOffer==#queryString should work.
Read the following document:
http://commons.apache.org/ognl/language-guide.html
In the sector [Operators], there is a table describe all the operators.
If you think the test result is not correct, you need print out the
variables, to check what value they really are.
2011/12/12 mohan rao mohanara...@gmail.com:
s:set var=selectedOffer value=%{ecOffers.dicountKey}/
s:iterator var =entry value = #session.discountOffers
s:set var=queryString value=%{#entry.key}/
s:property value=selectedOffer.equals(queryString)/ It supposed to
print true or false. But not printing any value
s:property value='#selectedOffer==#queryString'/ Printing false even they
are same. (I think it's checking reference.)

Re: Dynamically setting the template directory in an Action
My suggestion: You can create a file(or folder) link on your file system. From the view of your web app, it works like a file(or folder) inside the [document root directory], but the real file(or folder) is actually somewhere outside the [document root directory]. 2011/12/8 Gurcharan Singh gurcharan.sa...@gmail.com: In the same line, I've a question - How to setup Struts2 to use templates which are located outside document root directory.

Re: struts2 string to map conversion
What is your client side code (JSP)?
In OGNL expression, a value assignment is something like:
aMap[aKey] = aValue
So, you need create HTML code like:
input name=aMap[aKey] value=aValue /
On the server side, the OGNL expression will be converted into Java
method invoking like:
yourAction.getAMap().put(aKey, aValue)
Unfortunately, the Java generic system don't know the element data
type of your Map,
so, the data type for [aKey] and [aValue] may be a problem.
I suggest you just declare the map as MapString, String, and do the
conversion by yourself.
All I talked above are not tested, just suggestion.
You need do the test and check if it is correct.

Re: Customizing validation
Looks like you want some pre-condition check before the validation.
If and only if the pre-condition is true, the validation will be executed.
I did the same thing several years ago.
There are 2 solution I tried:
(A)Inherit all the struts2 bundled validators, add some pre-condition
check code,
if and only if the pre-condition is true, invoke the method of the
base class. The base class (struts2 bundled validators) will do the
left work.
BTW, the pre-condition should be passed into the validators via
param, so the validators will not include any business logic and
they can be reused.
And since your pre-condition is a session attribute, I think you can
check it's value by OGNL expression. I am not very sure for this. If
you can not access session attribute via OGNL, maybe you need a
[getCountry] method in your action class, so the OGNL can retrieve the
value.
You don't need reinvent the whole wheels, but extend the existed wheels.
Source code like:
public class XXXValidatorEx extends XXXValidator {
private String condition; // here is the pre-condition in OGNL
public getCondition(); // omitted
public setCondition(); // omitted
private boolean evaluateCondition(){
// omitted
// you can read the code of [ExpressionValidator] and
[FieldValidatorSupport], to learn how to evaluate an OGNL expression.
}
public void validate(Object object) {
boolean result = this.evaluateCondition();
if (result ) {
super.validate(object);
}
}
}
There are about one dozen bundled validators, and the source code of
the inherited validators will be almost 100% same (only except the
class name and the base class name).
This will be a little ugly, but we have no choice, because Java don't
support multi-inherit or interface-delegation.
My choice was, generating all these source codes via FreeMarker, so I
need maintenance only one template file, but not one dozen of class
source codes.
(B)The other solution is much lighter.
No need the enhance the validator class, but express your
pre-condition and your validation rule all by expression.
like:
validator type=expression
param name=expression(!pre-condition) or (check-rule)/param
/validator
This will be easy to do, but hard to use,
because you must translate all the validation rules into some OGNL expression
Anyway, I think the final and most beautiful solution should be,
adding some [pre-condition checking] into the Struts2 bundled
validators themselves.
But this is out of our control, hope the developers of Struts2 can here this.

Re: Customizing validation
Changing the [validation interceptor] will switch on/off the all validations by one pre-condition. But what he need is: if and only if pre-condition-A is true, run validation-A; if and only if pre-condition-B is true, run validation-B; etc... So, I think the right way is, change the validators. 2011/11/29 Dave Newton davelnew...@gmail.com: If the goal is to execute validations based on arbitrary preconditions (I missed the original req) the *easiest* thing to do might be to just extend/usurp the existing validation interceptor to do that precondition check. d. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Re: Customizing validation
Yes, of course you are right. But what you talking about sounds like to change S2 mechanism itself, which we can not do. As a S2 user but not a S2 developer, the simplest way is to write a new validator.. Of course, If the [pre-condition based validation] is a common request, I think it will be great if we post it to the S2 feature request list. 2011/11/29 Dave Newton davelnew...@gmail.com: If the need is across the application, then modifying the app-wide interceptor makes sense. App-wide rule-based validations require something higher-level than reworking existing validators, or writing new ones, to express something that is likely declarative in nature. Seems more like run this bunch of validations based on this condition--rather than simply look up validations based on the action name, lookup should be based on the condition(s). That's mechanism-level, not validate-level. d. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: getText returns NULL when formating number using l10n
If you want a definitive solution, i suggest you create a new method like:
getTextEx(.)
in your action,
in this method, you can check the parameters, if they are null, change
them to empty string, and then invoke the original getText method.
you can put this method in the base class of your actions, so you can
use it in all the actions.

Hi. I'm trying to internationalize my application, and for that i need to

On Struts 2 documentation it says:
to input a number, one might have noticed that the number is always
shown
in the Java default number format. Not only that this is not nice, if
you
are in a non-en locale, it will also cause trouble when submitting the

since type conversion is locale aware. The solution is to again use the
message formats as defined above, by using the getText Method of
ActionSupport:
s:textfield key=orderItem.price
value=%{getText('format.number',{orderItem.price})} /
This maps to the method signature getText( String key, Object[] params )
in
ActionSupport.
(http://struts.apache.org/2.x/docs/formatting-dates-and-numbers.html)
It display the number in the correct format when i use the value like
this,
but when the value is null it shows null instead of a empty textfield.
Does anyone know how to fix it?

Re: getText returns NULL when formating number using l10n
I have read the source of java.text.MessageFormat, looks like it
output a null text to the result String when the argument is null.
I think you can create a read-only property in your action (or your
data model class), and implement the null check and format process in
this property,
code like:
public String getPriceDisplay(String formatPattern) {
if (this.price == null) {
return
}
else {
format it by the formatPattern
}
}
and use this property in the jsp tag,

Re: Dynamically setting the template directory in an Action
(1)I believe the word [template] in struts2 means,
the template file to render a struts2 tag.
for example, the file
[struts2-core-2.2.3.jar]/template/xhtml/form.ftl
is a template file to render the tag s:form using theme xhtml
(2)what you are trying to do, is to change the jsp file location which
will be used to render the action result. This is different to the
[template].
maybe you can use [Parameters in action result definitions], described
by the following document:
http://struts.apache.org/2.x/docs/parameters-in-configuration-results.html
2011/11/11 Chris Rijk chrisr...@gmail.com:
Hi all,
Referring to this page:
http://struts.apache.org/2.2.1/docs/selecting-template-directory.html
It says the template directory can be specified in the session, for example
to allow the user to change it on a per-session basis. I've been trying to do
this for my application, but can't get it to work.
I'm using the conventions library. If I copy WEB-INF/content to
WEB-INF/content2 I can add a tag like @ResultPath(value=/WEB-INF/content2/)
to an Action to change the template directory used to render the results, and
this works as expected. However, that works on a per action/class basis, and
I want to do it on a per session basis.
I've tried setting templateDir in the session but this has no effect. Any
ideas?
For example, I've tried this in an action implementing the
ServletRequestAware interface:
public void setServletRequest(HttpServletRequest arg0) {
HttpSession sess = arg0.getSession(true);
sess.setAttribute(templateDir, /WEB-INF/content2/);
}
I also tried implementing SessionAware, eg:
public void setSession(MapString, Object session) {
session.put(templateDir, /WEB-INF/content2/);
}

Re: Right way for exception handling
Hi, Ilya:
But struts-2 breaks this scheme.
1) it does not pass exception to container so container can't log it.
I used struts2 for several years.
In our projects, struts-2 does not break this schema.
I have read the source of struts2. When an exception is thrown from
action execution, struts2 will catch it, and
(1)set 500 error to the response code
(2)put the exception instance into request attribute
[javax.servlet.error.exception] and [javax.servlet.jsp.jspException]
source code like this:
package org.apache.struts2.dispatcher;
class: Dispatcher
// WW-1977: Only put errors in the request when code
is a 500 error
if (code == HttpServletResponse.SC_INTERNAL_SERVER_ERROR) {
// send a http error response to use the servlet
defined error handler
// make the exception availible to the web.xml
defined error page
request.setAttribute(javax.servlet.error.exception, e);
// for compatibility
request.setAttribute(javax.servlet.jsp.jspException, e);
}
// send the error response
response.sendError(code, e.getMessage());
you can handle exception by:
(1)add this setting into web.xml:
error-page
exception-typejava.lang.Exception/exception-type
location/some_path/errorException.jsp/location
/error-page
(2)create a errorException.jsp
2011/11/12 Ilya Kazakevich ilya.kazakev...@jetbrains.com:
Hello,
In bare container (tomcat) everything is good: Servlet throws exception and
container logs it and displays 500 error page with certain status.
Each uncounght exception should lead to 500 error because uncought exception
is _program_ error.
But struts-2 breaks this scheme.
1) it does not pass exception to container so container can't log it.
2) even if I use exception interceptor (ExceptionMappingInterceptor)
struts does not set 500 error code to my result. So I have to set it in my
JSP (or servlet) manually.
I can't use static 500 error page as I did in tomcat.
So, my questions are:
1) Why do not struts passes exception to container by default? Could I
configure it to do so?
2) If struts can't do it -- how can I make it to send 500 status for my
exception? I do not want to configure my jsp
3) Who really needs exeption handling in struts? Somebody wants user to be
redirected to different actions based on exception type? What for? Smells
like exception-based business logic moved from java to struts.xml and does
not look like good practice.
I need to write a lot just to get back to default container behavior (500
status and logging):
1) Create _new_ stack to set logEnabled and logLevel
2) Configure package to use it
3) Add global error result
4) Add global exception handling
5) Create JSP with status 500 instead of my 500.html page
Is not it too big for such simple task?

Re: [S2] Displaying user entered values after failed type conversion while using getText()?
I have 2 suggestion:
(A)Declare the input data field in your action as a String, instead of
date or integer.
So, the String field can hold anything input from client side.
But this will be inconvenience to use, because you have to convert the
string value
to the date or integer value by yourself, before you can use it.
Another solution is:
(B)Declare 2 fields in your action.
One as date or integer, to hold the type converted valid value.
Another as String, to hold the original input text.
On the input page side, you also need 2 form elements.
One is input, which will send data to the [real value] field,
and another is hidden, which will send data to the [original input
text] field.
User can only see the input, and input data in it.
you can create some JS code, to copy the input content to the
hidden element, before the form be posted.
When the type conversion fails, and the input page displayed again,
the hidden element will contains the original input text,
and the input element will contains empty text.
You can create some JS code, to copy the hidden element content to
the input element, after the page loaded.
Or, you can simply set the value of the input element from the
[original input text] field of Action.
Hope this helps.
2011/11/17 Burton Rhodes burtonrho...@gmail.com:
I am having an issue with displaying the original value entered on a
form after failed type conversion. This bug is caused by my use of
getText() in the form value fields. I'm curious how one solves this
issue for making sure the field is formatted correctly upon display,
but also making sure the users see the orignal malformed entry after
failed type conversion. I have a few examples below. The last one
displays works the way it should. The top two only present an empty
field upon failed type conversion.

Re: Struts 2 Initialization Plugin
I think lazy initialization is a simple choice, because it is not dependent on the J2EE container, this make your code easy to test. If you worry about duplicated-initialization triggered by multi request, the simple solution is, make your initialization code [synchronized], using reserved word [synchronized] of Java language. However, if your initialization process is too heavy, the lazy initialization mode will make the first access slow. If you care about this problem, the [ServletContextListener] and [initialization servlet] is a better choice. As Eric and Chris said, they can be good entry point to call your initialization process. I suggest： (1)implement your initialization process as a util-class or something, so you can do unit test, out of the J2EE context. (2)call the initialization process from [ServletContextListener], or [initialization servlet], or some lazy initialize code as you want. The basic principle is: (1)implement the real business logic in an independent mode (2)create some adapter code, to connect your business logic and your run time context 2011/11/11 Scott Smith ssm...@mainstreamdata.com: In struts 1, I used org.apache.struts.action.PlugIn as a way to create an object at web app startup and put it into the application context so that all sessions had access to it. What's the equivalent method in Struts2? That is, how can I have an object created at web application startup. I guess the alternative is lazy initialization (first guy who tries to access it and doesn't find it, creates it, and saves it into the app context; down side is I might end up with several sessions trying to create it until one finally makes it to the app context).

Re: Struts 2 date field problem
Did your problem happens when date input or output?
For output case, the s:date tag can let you choose the format to use.
See:
http://struts.apache.org/2.x/docs/date.html
For input case, Struts2 can convert HTTP parameters from String into
most of data type you need, include Date.
But for Date, it [uses the SHORT format for the Locale associated with
the current request]
So, if your parameters can not be converted to Date correctly, maybe you need:
(1)change your input format
(2)or build a new Type Converter to support the format you want.
This page describes the details:
http://struts.apache.org/2.x/docs/type-conversion.html
And, the following code is a DateConverter we used in our project,
which support several date formats:
= START =
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Map;
import org.apache.commons.lang.StringUtils;
import org.apache.struts2.util.StrutsTypeConverter;

Re: slow request/response may be because of validation/conversion
I think conversion and validation should not be turned off. The [conversion] convert http parameters (which is String) to the real data type so your action can accept. The [validation] check the parameters if they a valid. And also, normally, conversion and validation should not take too much time. The log you showed to us start at 2011-10-10 10:55:42,187 and finished at 2011-10-10 10:55:42,393 So, it only cost 200 ms. I think you need printout more debug info, and find out where is the real bottle neck. And, as Carl said, the setting of [struts.devMode] can make Struts2 slow.

I took a quick look at Struts1 document. Looks like the following information can help: http://struts.apache.org/1.x/struts-taglib/tagreference.html#html:link = START = To specify a single parameter, use the paramId attribute to define the name of the request parameter to be submitted. To specify the corresponding value, use one of the following approaches: Specify only the paramName attribute - The named JSP bean (optionally scoped by the value of the paramScope attribute) must identify a value that can be converted to a String. Specify both the paramName and paramProperty attributes - The specified property getter method will be called on the JSP bean identified by the paramName (and optional paramScope) attributes, in order to select a value that can be converted to a String. If you prefer to specify a java.util.Map that contains all of the request parameters to be added to the hyperlink, use one of the following techniques: Specify only the name attribute - The named JSP bean (optionally scoped by the value of the scope attribute) must identify a java.util.Map containing the parameters. Specify both name and property attributes - The specified property getter method will be called on the bean identified by the name (and optional scope) attributes, in order to return the java.util.Map containing the parameters. As the Map is processed, the keys are assumed to be the names of query parameters to be appended to the hyperlink. The value associated with each key must be either a String or a String array representing the parameter value(s), or an object whose toString() method will be called.

Re: Unicode Encoding request parameters
You don't need an extra-filter.
The S2 default encoding is UTF-8.
The code of S2 filter is:
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter:
public void doFilter(..) {
..
prepare.setEncodingAndLocale(request, response);
..
}
and the code of PrepareOperations is :
org.apache.struts2.dispatcher.ng.PrepareOperations
public void setEncodingAndLocale(HttpServletRequest request,
HttpServletResponse response) {
dispatcher.prepare(request, response);
}
and the code of Dispatcher is:
org.apache.struts2.dispatcher.Dispatcher
public void prepare(HttpServletRequest request,
HttpServletResponse response) {
String encoding = null;
if (defaultEncoding != null) {
encoding = defaultEncoding;
}
..
if (encoding != null) {
try {
request.setCharacterEncoding(encoding);
} catch (Exception e) {
LOG.error(Error setting character encoding to ' +
encoding + ' - ignoring., e);
}
}
..
}
and the code of property [defaultEncoding] is:
@Inject(StrutsConstants.STRUTS_I18N_ENCODING)
public void setDefaultEncoding(String val) {
defaultEncoding = val;
}
the value of [defaultEncoding] will be injected by the property
[StrutsConstants.STRUTS_I18N_ENCODING]
which is struts.i18n.encoding.
And this property is defined in [struts-default.properties], which's
value is [UTF-8]:
struts.i18n.encoding=UTF-8
You can read the following S2 documents:
http://struts.apache.org/2.x/docs/strutsproperties.html
If you want to change the default encoding, you can change the value
of property [struts.i18n.encoding].
By the way.
This encoding setting only works for the POST params (which are part
of the form element).
For the GET params(which are part of URL), the encoding can not be set
in J2EE context.
It will be parsed by the J2EE container (e.g: Tomcat) BEFORE your code
is executed.
In this case, the solution are:
(1)do not use non-ascii chars in URL params
or
(2)change the Tomcat setting about url param encoding: [URIEncoding].
It is descriped in this document:
http://tomcat.apache.org/tomcat-6.0-doc/config/http.html
2011/9/20 Zoran Avtarovski zo...@sparecreative.com:
We have a struts2 multilingual web app that requires request parameters be
encoded as Unicode (UTF-8).
In order to get the POST parameters to work we had to implement a character

use of another filter. We'e set the struts.i18n.encoding property to UTF-8
and I don't know what else to do.

Re: Is it possible to redirect after a Stream result action has completed?
I guess you can not do this. Because there should be ONLY ONE HTTP response for every HTTP request. So you can only return a file downlod or a redirect to the client, but not both.

Re: Calculate module of index in Struts2 iterator
That's just wired. The first idea in my head was, may be there is lacks of brackets in your expression. But then I checked the document of OGNL: http://www.opensymphony.com/ognl/html/LanguageGuide/apa.html Accordinting to this document, the operator [%] has higher precedence than operator [==]. Which means, the original expression without brackets should be same as the expression with brackets. So, I did not talk about the brackets thing.

Re: Iterator: field errors.
Since after validation fails the iterator grid also empty I think, you need separate the field names by list index -- since your data model is a list--, to indicate which [textfield] should be captured by which POJO element. And also, you need separate the field name of validation error, to indicate POJO element it belongs. So, i think code should likes: JSP: s:iterator values=myList status=rowStatus s:textfield name=myList[#rowStatus.index].name / s:fielderror name=myList[#rowStatus.index].name / /s:iterator Validation: addFieldError(myList[index].name,getText(error.code)); - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Problem using scriplet object in s:if tag
It don't works, because the JSP local variable is not an OGNL local variable.

An OGNL local variable should be [put into] the value stack of OGNL context, before you can reference it in other OGNL expression. Before you can reference an OGNL local variable, you need define it, using s:set tag (In struts2).

Re: any option parameter for populating parameters to my bean?
Can you show us the entire Exception stack?
I guess, this may be a type conversion error.
According to this struts2 documents:
http://struts.apache.org/2.x/docs/type-conversion.html#TypeConversion-BuiltinTypeConversionSupport
XWork will automatically handle the most common type conversion for
you. This includes support for converting to and from Strings for each
of the following:
dates - uses the SHORT format for the Locale associated with the
current request
So, I think the following things should be checked first:
What the Locale associated with the current request is?
What the short format of this locale is?
Is your input string 2010/12/12 12:00:00 match this short format?
The default date converter looks like depends on the Locale
associated with the current request.
So, the format it takes will vary.
If you want this, you need create a new converter which takes a fixed
date format.
I did this before, it's not difficult, if you following the document.

If the value of start is '2010-12-12 12:00:00',the parmameter start can be
populated to my bean correctly,however if the format is '2010/12/12
12:00:00',it will show me a error can not parser the date',so I wonder if
there is any parameter can be set for populating parameter?

Re: any ideas about handle user's relogin using interceptor?
The problem will be: (1)How to save the information about who is logged in from which session. and (2)How to check this information before every action execution For problem 1, if you only have one app server, you can save this information in global variable, if you need support multi app servers, you can save it into DB. The data structure should like MapUserID, SessionID (in global variable) or TABLE (UserID VARCHAR, SessionID VARCHAR) (in DB) For problem 2, you are right, Interceptor will be a good choice. I think the whole architecture should likes: (1)After user login, save the logged in status into global variable or DB, and into current session. (2)Before every action execution, extract logged in user id from current session, and then check the global variable or DB, see if this user is logged in from the same session. If the same user is logged in from some session else, this means he/she has re-logged in from somewhere else, so you can remove the logged in status from current session, and then force the user login again. For example: (1)UserA, logged in from ComputerA. Let's say the session is SessionA. So in SessionA, the logged in user ID will be UserA. And in the global variable or DB, UserA will be marked logged in from SessionA (2)When the same user login from ComputerB. Let's say SessionB. In SessionB, the logged in user ID will be UserA. And in the global variable or DB, the logged in status of UserA will be overwritten by logged in from SessionB (3)Request any page again from ComputerA. The Interceptor can extract the logged in user id (which will be UserA) from current Session (which will be SessionA). And extract the logged in status from global variable or DB, which will be logged in from SessionB, and different from current session. So the Interceptor can say, UserA has re-logged in from some where else. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

The only data need to save is UserID and SessionID, I think it will not over 100 bytes per user. For 1000 user, the total memory will not over 10MB. So, you don't have to worry about memory problem. For the DB solution, if you worry about response speed. You can change the solution: Do not check for every request. Do it with some interval instead.

Re: Incorporating action interceptor configuration parameters into a message
I have read the source code of FileUploadInterceptor.
I think it do the message getting in it's private method, and dose not
use the maximumSize as a message format param.
So I believe there is no simple way to extract interceptor interceptor param.
The simplest way I known is, hard coding the value in your message
properties file, like:
struts.messages.error.file.too.large=File {1} is {3} bytes which
exceeds the maximum 100123.
It is a little ugly, but looks like the only way.
The other way is, create a new class extend from
FileUploadInterceptor, and override the error message building part,
add the maximumSize as a message format param.
But it need many code, I don't think this issue is worth doing so may work.

Re: labelizing submit buttons
I think your tag has a leak of attribute method Your code: s:submit key=btn.search / will generate HTML likes: input type=submit name=btn.search value=Search/ When you click this button, there will be a http request parameter like btn.search=Search. Struts2 will accept this parameter, and try to save it to your action property. So, there will be a property setting, which cause method invoking likes: YourAction.getBtn().setSearch(Search) But your action does not have a property named btn, so getBtn() will get a null, and of cause the setSearch part will fail. If you add a method attribute to submit tag, like: s:submit key=btn.search method=search / It will generate HTML like: input type=submit value=Search name=method:search / Notice, the name is now method:search So, when you click this button, the http request will be: method:search=Search.

Chris is right. On the client side, there is not such a concept of Struts Action.There is Server Side Resource only.

(Post or Get) (2)Server side do the validation first. When the param data is not good. Do nothing, and send a FAIL FLAG+ErrorMessage as response. (3)When the validation passed, insert data into DB, and send a OK FLAG as response. (4)Client Side JavaScript receive the response. If it is a FAIL, show error on the page. If it is a OK, append data to the table. About the response, You can use plain text, HTML, XML, or JSON.

When you call the get(index) method on it, it will create a new item instance if the item dose not exist yet. By using this AutoList, when BeanUtils try to invoke method likes getListe(0).setNome(someValue), the item instance will be created automatically if need. In your case, my suggest is: (1)use AutoList, instead of Array Or (2)Since you have done the array/item initialization in the the method setNom(int index , Personne nom), so you can use this method instead of getListe[0].setNome(someValue). Which mean, in html side, the data name should be nom[0] instead of liste[0].nom How ever, I recommend AutoList solution strongly, because I believe this is a very common problem in Struts1. You may meet it somewhere else, so AutoList class will be very convenient. And also, if you use AutoList, you don't have to change the data name on the html side, which means, you can use struts tag lib as normal. If you need this AutoList class, I can send it to you. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

There will be only one class, which will be the class of the elements in the List.

2010/11/27 Peter Nguyen pe...@peternguyen.id.au:
Li,
I think the issue is here is most likely point 3. When the form is submitted,
I suspect struts is trying to call getListe(int) to retrieve a Personne bean
before calling the respective setters.
So in this case, Dominque probably just needs an additional getter in the
action form that will return the required bean:
public Personne getListe(int i) {
return (Personne) liste[i];
}

Re: File Download with multiple files. Design question
Any examples of doing this in struts 2 You can get the HttpServletResponse by: ServletActionContext.getResponse() And then, you can set the download file name, by: response.setHeader(Content-Disposition, attachment; filename= + fileName); And then, you can get the OutputStream, by: response.getOutputStream() Finally, you can output zipped data to the OutputStream. how to navigate to the next display after the download? I believe you can not navigate to the next page. Because for one http request, the server side can send only one response. If you want to download file and then show next page, it need 2 responses. I think this is impossible mission for one http request. If you send a file download response, then the browser will download it, and don't refresh the page, which means the current displayed page will remain. If you really want to implement this, may be you need some client side JavaScript to send a file download request first, and then send another request to display the next page. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Databinding a checkboxlist

2010/11/19 Altenhof, David Aron dalte...@iupui.edu:
Trying to figure out a way to do the following without much luck.
I have an enumeration with a list of menu options and corresponding labels
such as:
public enum Color {
RED(Red),
BLUE(Blue),
GREEN(Green);
private String myLabel;
private Color(String label){ this.myLabel = label; }
public String getLabel(){ return this.myLabel; }
}
This can be easily used to create a checkboxlist:
p Please enter your favorite colors: /p
s:checkboxlist
list=@my.site.enums.co...@values()
listValue=label
name=colors
/
I also have a set of Color on the Action that came from the persistence layer
and has a Color for each of the user's (past) choices:
public SetColor getColors() {
return colors;
}
Question is: How do I automagically check the appropriate checkbox if they
have a corresponding value in getColors? I guess I'm looking for something
like a databind from other languages.
I suppose one could iterate over the enum and create individual checkboxes
for each while testing to see if they have an already selected color, but I
thought there might be a more direct way...

Re: struts2.1 validation problem! with fileUploadStack
Maybe you can add a property in your action which return the current
date. And reference this property in your validation configuration.
Or create a Static method in an Utility class, return return the
current date, And reference this property in your validation
configuration.
If both of these don't work, you have to implement your check by a
validate method in your action.

Re: File Download with multiple files. Design question
My suggestion: (1)I believe you can use ZipOutputStream to output the zipped data to the response OutputStream directly, instead of a temp file. So no temp file need to be created. OR (2)You can create a batch application, repeatedly run it with some interval (use cron or something). And in this batch app, you can check the timestamp of your temp files, and delete them if they are old enough. I think the first way is the best, because there is not any side effects. But the second way is also valuable, because it can help you to clean up your working folder when you really need temp files. 2010/11/19 RogerV roger.var...@googlemail.com: Hi I have a requirement to present the user with a list of files stored on the server, and then download the files selected to the user. If the user selects a single file - no problem. However if the user selects multiple files, then, unless anyone knows different, all the files have to be sent in the single input stream read by the stream result. Therefore I create a temporary file with File.createTempFile() and use the ZipOutputStream to zip the files and then return an input stream over the temp file. This works suprisingly well. However, the problem I've now got is, how to get rid of the temp files I am creating on the server? file.deleteOnExit() is no use because the server VM will (in theory) never shutdown. Once the download is complete Struts automatically re-displays the original selection screen and provided the user uses the applicatoin supplied navigation to exit then I can delete the temp file, but if they simply close the browser or use the browser back button to navigate away I'm still left with the temp files sitting around. Creating the zipfile in memory is not an option as some of these can potentially be huge if the user goes mad and selects everything in sight. Is there someway of detecting/intercepting the fact that the Stream result has completed before Struts gets on with deciding what .jsp to display next so that I can safely clean up? Any other suggested approaches would be welome.

Re: Another stupid question re: Interceptors
I suggest you to do these things in the following way: (1)put 2 method in IdentifyAction. The first [execute] method returns [input], show the input page to user. (2)In the Identify-input.jsp, submit fields to [IdentifyAction] itself, but another method: [verify] (3)when validation fails, the result will be [input] automatically, which means, the input page will be shown again. (4)when validation validation passes, your method [verify] will be executed. You can implement your business logic in it. If the verification fails, you can return a result [input], and back to the input page again. If the verification pass, you can return another result, and forward(or redirect) to the next action; or you can return a result [success], show the Identify-success.jsp page. (5)another thing need to notice is, method [execute] should be marked by [skipvalidation] annotation - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Setting object from param tag fails in Struts 2.2.1
I don't think this is a bug. Because the basic idea of WEB app is: everything is passed as String. Actually, there is a special layer in struts2 for data conversion. Your action may take int/long/boolean/date or something else as it's parameters, but all the original request parameters are String, and they are converted to appropriate data type by struts2 automatically. See: http://struts.apache.org/2.2.1/docs/type-conversion.html So, if param tag convert your parameter into String, I don't think this acting is incorrect, because the Action which receive this parameter should take the responsibility to convert it from String to something it need. In your case, your are calling an action from some action else. But think about calling it from the client side (for example: in browser), how could you pass an object instance as parameter? The only thing you can pass is String. So, my suggestion is: (1)Don't use an object instance as the parameter. Use the object id (can be int, string, and so on) instead. And in the action, load the object by id If you worry about the performance issue caused by object loading, you can use cache. OR (2)If your action will be accessed from other actions only, but never be called from the client side. Then you can delete the parameter from the action. Use request (or session) attribute instead. Before calling the action, put the object into request (or session) attribute. And in the action, load it from request (or session) attribute. 2010/11/17 Raj Nagappan r...@velocitylabs.com: I did some experimenting with this by removing the lazy load and putting the actual object directly on a property in the action class.

But the problem still continues because, when I create the Welcome Struts application in Netbeans, In the package com.myapp.struts there is a default properties file create called ApplicationResource.properties, which has in English. welcome.title=Struts Application welcome.heading=Struts Applications in Netbeans! welcome.message=It's easy to create Struts applications with NetBeans. As I wanted to create a multilanguage application in Spasnish and English I created MessageResources_es.properties, which the following content. welcome.title=Holamundo Struts welcome.heading=Bienvenida! welcome.message=Holamundo Struts And In the Struts-config I add the following line message-resources parameter=com/myapp/struts/MessageResources_es/ below to message-resources parameter=com/myapp/struts/ApplicationResource/ But when I run the application it still gives me the same error.

Re: Problem with Struts 1 form
(1)Is there any Proxy Server between the client PC and the Web App Server? (2)When the action going wrong, is there any Error or Exception message on the Server side? (3)There is a configuration item to control the max-file-size you can upload. You may need change it to more than 200MB. [maxFileSize - The maximum size (in bytes) of a file to be accepted as a file upload. Can be expressed as a number followed by a K, M, or G, which are interpreted to mean kilobytes, megabytes, or gigabytes, respectively.

Re: Problem with Struts 1 form
3. No such value is set. So I guess it is taking default value right now. As I said, You may need change it to more than 200MB. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Missing message for key welcome.title in bundle (default bundle) for locale es
try message-resources parameter=com/myapp/struts/MessageResources/ This is right. The name of a resource bundle, should not include the locale suffix. Actually, a resource bundle, contains several resource files which have the same base name and different suffix for each locale. For more information, see: http://download.oracle.com/javase/6/docs/api/java/util/ResourceBundle.html and make sure your locale is es_ES and not just es (not sure if it matters, but just to be on the save side) It matters. When user locale is [es_ES], the resource locale can be used should be (in the priority order): (1)es_ES or (2)es or (3)NONE When user locale is [es], the resource locale can be used should be (in the priority order): (1)es or (2)NONE Which means, resource locale [es_ES] can not be used for user locale [es] - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: ONGL EL expression problem.
s:iterator value=list.{?#this.id == titleID'}
Is there an unnecessary quotation mark after [titleID]?
Try delete it and see if works.
If it still not working, My suggestion is:
(1)you can implement the search logic in the method [viewPage], and
access the search result via a new property.
or
(2)use a Map instead of a List, so you can retrieve the value by the key
or
(3)in your action class, add a new [Object Indexed Property] which
retrieve the value from your list by the titleID

2010/11/9 Mead Lai laiqi...@gmail.com:
Hello all,
I have a Action contain a list ListadminTitleVO, and a String property
titleID, how to display the value from list?
Detail code is here:
//**IndexAction**
public class IndexAction{
private ListAdminTitleVO list;
private String titleID;
//get set
public String viewPage()
{
//#{'a1':'admin','a2':'manager','a3':'member','a4':'user','a5':'guest'}//
simple data list
this.list = BS.getAdminTitleList();
//set a id
this.titleID = a5;
return view;
}
}
//**AdminTitle**
public class AdminTitle{
private String id;
private String name;
// get set ...
}
//**JSP page**
s:select list=list listKey=id listValue=name value=a4/, 'user'
item will be selected.
Now, I want to display the name in plain text way! Get the name by titleID
in the Action
${list[0].name}, I can get first item from List, and display the name=
'admin';
but
${list[titleID].name} is showing Error on page.
How can I get the adminTitle.name on the page, by the certain
adminTitle.id
The following code run fine.
s:iterator value=list.{?#this.id == 'a4'}
s:property value=name / ：s:property value=id /
/s:iterator
but
s:iterator value=list.{?#this.id == titleID'}
s:property value=name / ：s:property value=id /
/s:iterator
it show nothing...
What shall I do to pass the this.titleID in the Action into the struts2
Regards,
Mead

Re: Have you ever used InputConfig annotation?
Actually, I am using interface [ValidationWorkflowAware] instead of annotation [InputConfig] for the purpose of repopulation when input validation fail happen. You can see how ValidationWorkflowAware work when you read the source code of DefaultWorkflowInterceptor. Basically, the idea is similar. But, [InputConfig] need you to appoint a method name every time. So I think it is more convenient if I use ValidationWorkflowAware. My solution looks like: (1)Define a class BaseAction as the base class for all my Action class (2)In BaseAction, implement [ValidationWorkflowAware] (3)In the method [getInputResultName], call a protected method [loadData] which is empty(for now), and then return [INPUT] as the result name (4)In specific action class, override the method [loadData], and do the real repolulation job for this page So I can keep all the action class do the same work in the same way. When the project and the develop team get large, I think the consistency of code convention is much important than just get the job done. Hope this helps. 2010/11/6 Alfredo Manuel Osorio Martinez alfredo.oso...@afirme.com: Hello, By looking at DefaultWorkflowInterceptor I saw an annotation that I didn't know existed. I am talking about: com.opensymphony.xwork2.interceptor.annotations.InputConfig I think it can be used for input repopulation and can be used as an alternative to Preparable and s:action/. What surprised me was that there is a little documentation about the use of the annotation or examples. Haver you ever used this one before? Is it a good idea to use it for input repopulation for example collections for selects in case a validation fails?
