how to avoid action chaining
hi, I am hearing that action chaining is something we should avoid, however, I am not sure what's the common practice for this use case: given User and Department, we need to list User/Department, view User/Department; when listing User, we also show their department. When listing Users, we may want to display the department details of the selected user. after which, we want to come back to the User Listing page. So to avoid action chaining (from UserListAction to ViewDepartmentAction), we can use a dispatch action for UserListAction, which includes a viewDepartment. But in DepartmentListAction, we also have a similar viewDepartment. Using action chaining, we can have a seperate ViewDepartmentAction which can be used by other Action classes also. So what's your practice for this case ? lixin

Re: calling method of a bean from JSP
What are you trying to achieve? Maybe you're trying to put logic in your
JSPs that more properly belongs in an action.
thanks. what i am trying to do is to get the value of a field. Say I get a
list of items:
class item {
Set values;
...
}
The item has a set of Values:
class Value {
Attribute attribute;
String value;
}
What I wanted to do is to get one particular value based on attribute ID. in
this case I have to add a method in the Item class, someting like this:
String getValue (String id) {
while (it.hasNext()) {
Value value = (value) it.next();
if (value.attribute.getId().toString().equals (id)
return value.value;
}
So from JSP, I would like to call this method c:out value=${item.getValue
(id}/
Re: calling method of a bean from JSP
c:out value=${beanName.methodName}/
I thought this is for getting the value of a property ? and how to pass a
parameter to the method ? I think I have tried that but does not work.

can not enable I18N properties
Hi,
I am trying to enable I18N in my struts based application, here is what I
have done:
- added a LocaleFilter, which I copied from Appfuse:
String locale = request.getParameter(locale);
Locale preferredLocale = (*null* == locale) ? *null* : *new*Locale(locale);
HttpSession session = request.getSession(*false*);
* if* (session != *null*) {
* if* (preferredLocale == *null*) {
preferredLocale = (Locale) session.getAttribute(Globals.*LOCALE_KEY
*);
} *else* {
session.setAttribute(Globals.*LOCALE_KEY*, preferredLocale);
Config.*set*(session, Config.*FMT_LOCALE*, preferredLocale);
}
* if* (preferredLocale != *null* !(request
*instanceof*LocaleRequestWrapper)) {
request = *new* LocaleRequestWrapper(request, preferredLocale);
LocaleContextHolder.*setLocale*(preferredLocale);
}
}
chain.doFilter(request, response);
// Reset thread-bound LocaleContext.
LocaleContextHolder.*setLocaleContext*(*null*);
- created ApplicationResources_XXX.properties
- added message-resources parameter=ApplicationResources / in
struts-config.xml
- added %@ page language=java pageEncoding=UTF-8
contentType=text/html;charset=UTF-8
%
in each JSP file
- in my IE, I also added additional languages.
but i only saw english strings. no effect whethere I have html:html
locale=true/ or not.
anything else I miss out ?

ps. i debug the filter, it seems that the language is indeed saved in the

You might want to consider some kind of pessimistic locking. Basically you lock the object when you start editing and prevent all access to it for the duration of the lock. You could also do an optimistic lock which means that when you change an object it will only be committed if the object hasn't changed between the time you got your lock and the time you want to commit it. This doens't prevent you from having done unnecessary work however. Most db's support optimistic locking, but not pessimistic locking. If you want to use this at the application level you will have to do it yourself. You could put a variable somewhere to track wether an object is being edited and base access restrictions off of that. However you have to be very carefull about making sure you don't get any deadlock or race conditions. I suggest you delve into database world and read about how other people have solved this problem. mvg, Jasper On 5/30/06, Julian Tillmann [EMAIL PROTECTED] wrote: Hello everyone, Within our struts web application in which we have edit-actions within a user can be busy editing data in the form for several minutes.

Actually, you would store two, the current and the previous. Here's my concern... let's say you have page A and page B, from which you can go to page C. From page C you want to return to page A or B as appropriate. You could do this a number of ways, but what if you are using the common paradigm of a setup Action for a screen, and then a collection of Actions which really can be though of as event handlers for a given screen (could be a DispatchAction just as well, that wouldn't change anything). If you want to go back to page A from page C, and you got to page C by maybe submitting a form, then the problem is that you got to page C via an event handler in essence. But, when you return to page A, you really want the setup Action to fire again. So, just recording the last request isn't sufficient. If you have a base Action that sets that session attribute, then you can have only your setup Actions extend that base class. Then, when you want to return to the last page from any other page, you look up that value and you now know which SETUP Action you need to call. More precisely, you would look at the second value in session (think of it as a stack) because every time a setup Action is called you really need to push a value on the stack so that the second value on the stack is truly the last page, not the current pages' setup Action.

I set to ja in the session; I removed locale=true from JSP but the result is the same. Browser encoding is set to UTF-8. When I 'view source' in the browser, I saw html lang=zh if I set to Chinese.

I've never used JSF so firstly, is this now the way to go? Roughly, Shale is to JSF as Struts is to JSP: it provides a framework which supports best-practices application development with features that are outside of the scope of the basic Sun technology. Roughly that's pretty accurate :-), although there is one level of internal difference that you will want to be aware of. JSF includes a controller servlet (like Struts and other MVC frameworks), and supports other controller features like navigation, itself. Shale builds around the edges to add value (functionality and/or ease of use improvements), without any attempt to redundantly implement features that JSF provides by itself. One place I *don't* see Shale going, by the way, is to become yet another library of JSF components. There will be a few such components that integrate directly with Shale features (like the ones that integrate the Commons Validator facilities), but the whole idea of a standard component API is that you should be able to use *anyone's* components with it. If you're going to use JSF, you should probably check out Shale. I would agree with this ... especially for new app development. You can use struts-faces to connect JSF to Struts, but if you have no deep Struts experience, you wouldn't be gaining much of anything, and in fact you'd lose all the benefits that Shale has by virtue of learning from several years of Struts development experience. The integration library should be primarily considered as a tool useful in a migration strategy. Secondly, where can I find out more? And finally how steep is the learning curve? There doesn't appear to be the Shale equivalent of http://struts.apache.org Shale's website, by the way, is at: http://struts.apache.org/shale/ The feature descriptions have not all been fleshed out yet, but the javadocs are pretty thorough for those cases. I'm not sure what the second question was: about the learning curve? I'm not the one to answer that. But since Shale is a subproject of Struts, there is no shale.apache.org Since there has not been a full release of Shale, the struts-dev list is generally considered the more fruitful place for discussions about it.

Re: [OT] Recommendation of Instant Messagging System
Hi Erik, thank you so much for your information. it really helps me go in the right direction. i will do more homework on XMPP and Smack first. really appreciate your help ! lixin On 5/6/05, Erik Weber [EMAIL PROTECTED] wrote: See my other post, please, if you are limited to using HTTP. The modifications I made to Smack (1.4.2) are subtle, and the classes are pretty small, but they require some detail to explain properly. The library does work as is. It uses two threads -- one that parses incoming XML and dumps the generated objects into queues, another that actively polls queues and notifies your listeners. I found that in some cases where Smack expects you to use one model (active vs passive notification), you really would like to use the other. This led (I think) to a quote on the Web site that was something like some developers find that the Chat class doesn't meet their needs, so they implement their own using PacketCollector, etc.. So I made some modifications and wrote a couple new classes related to that. I prefer to write my own queues and Runnables because you have more control that way. If you are not comfortable doing this, don't worry, their stuff works fine as is. You can just register listeners and away you go, updating your GUI in event handlers. Yes, I would contribute my modifications, but first I need to document them (and also make sure they are still needed -- they update fairly regularly). I will share them with you either way if you go this route. Erik P.S. There are Applet chat systems out there that have been around for a long time. Don't forget to check those out. Also, there is at least one open source Swing client built on Smack that looks pretty good, especially in the area of SSL. See the Smack forums and you can find an announcement of it. Probably, there are JavaScript-based chat implementations out there too. If you are going to use JavaScript and have simple requirements, Leon's suggestion might fit the bill.

This solves action chaining but them I got the submit button problem: here is my jsp file: html:submit property=ListPermission.dispatch=done bean:message key=button.done/ /html:submit here is the partial action mapping: action /ListPermission ... parameter=ListPermission.dispatch ... /action the intersting thing is that when the 'Done' button is clicked, the property is not passed in as parameter.

need advice: session scoped objects or session scoped ActionForm ?
Hi, I am seeking your expert advice: I have a simple page with Done and Cancel buttons. If any of these buttons are clicked, I suppose to go back to the calling page - there are a few pages that will come to this page. It is a simple workflow type of thing. So I need to know the retutn URL, pls some other stuff. The question is, where do I keep the return URL which is passed in as request attribute ? Since the current page has some other buttons not just Done and Cancel, I use LookupDispatchAction, that means I have to keep the return URL in the session. Which one is a better solution: keeping it in the session scoped ActionForm or request.getSession().setAttribute ? It is easier to manage the return URL if put into ActionForm becuase it is isolated, no naming conflict-bur ActionForm is for UI components only; otherwise, I need to keep it in the session using a name reference something like myAction_returnURL, and also I need to handle the cleaning - it is still possible that the sting is kept in the session until the session is closed if the user does not click Done or Cancel. any best practice ? may be the best is to avoid using session scope objects but I just can not think of a way out for my use case. thanks in advance LX __ Do You Yahoo!?

Re: need advice: session scoped objects or session scoped ActionForm ?
actually I do not like either option. my understanding is: * session scoped obejcts (I mean those put into the session using request.getSession().setAttribute()) are like global variables. I need to take care of potential naming conflict-but I can not use fully qualified domain name type of naming convention because some tags resever the '.'; clean them when no longer used - but there are chances that they are not cleaned if the user does not click Done or Cancel but jump to other pages by select menu items; * session scoped ActionForm should not be used to keep application data but only UI related stuff The other possible solution is to use Workflow extenstion but I feel that it is not flexible enough. And in fact workflow extension keeps data in the session also so fundamentally no difference. I guess it is the limitation of the current J2EE implementation. Looks like I will choose to use request.getSession().setAttribute way of keeping some necessary data to support those use cases. ___ Do you Yahoo!?

RE: Validator with DispatchAction...help!...newbie
There is an interesting article talking about validation in DispatchAction. That may not be what you are looking for but I would like to know if the method suggestted by the author is a good choice or not: http://www.reumann.net/struts/articles/request_lists.jsp Another common practice is to have a isMutable() method in ActionForm. However, it relies on the Actions to play around the 'mutable' property carefully. And is something goes wrong and the property is set/reset properly, then things may go wild. Any comments ? lixin --- Robert Taylor [EMAIL PROTECTED] wrote: ValidatorForm, ValidatorActionForm, DynaValidatorForm, and DynaValidatorActionForm allow you to leverage the validation framework in Struts. How you use DispatchAction determines what you need to do to make it work with the validation framework. For example there are two basic approaches: 1. Differentiate different validation routines based on form name. Using DispatchAction you could use the same form and identify it with different names in the struts-config.xml file. You can then ensure that each action mapping using the DispatchAction used the appropriate form name to invoke the appropriate validation rules in validation.xml. 2. Differentiate different validation routines based on action mapping. Using DispatchAction you could use the same form with the same identity. You can then use different action mappings which all map to the same DispatchAction using the same form. Each unique action mapping would then invoke the appropriate validation rules in validation.xml. There are other variations of DispatchAction such as MappedDispatchAction and LookupDispatchAction. Each of these might be leveraged differently to work with the validation framework. I've yet to use them, so I can't offer any advice; however, recently, there have been some healthy threads on both. Just don't ask Rick about LookupDispatchAction and you'll be okay :) Now, it gets kind of tricky when you want to use DispatchAction (or some variant there of) to perform different validation routines using the same form name and the same action mapping. This is typical when you have a single form with multiple buttons, where each button invokes a different operation on the DispatchAction and you want to use different validation routines for each operation. Since validation routines basically key off of the name attribute of the form element in validation.xml, you can modify/override the getValidationKey() in ValidatorForm or ValidatorActionForm to return a name including the invoked operation. There are probably other ways to do this and most likely more elegant. I think you can also use the form name in conjunction with the page attribute as the validation key but I haven't done this yet. Digging around the source code always helps me to understand how things work. robert -Original Message- From: O.

Re: Help - struggling this for days !
yes, I have a few pages, forms and actions. the
strange thing is that some works fine. I in one
particula action, I copy the key used in another
action which works, but it does not work in this
action.
Here is the action defintion:
action path=/admin/SearchTemplate
name=searchTemplateForm
scope=request
validate=true
input=.searchTemplateDef
parameter=method
type=net.canal.admin.action.SearchTemplateAction
forward name=success path=.searchTemplateDef /
forward name=notfound path=.searchTemplateDef /
forward name=found path=.listTemplateDef /
/action
In SearchTemplateForm.java, I have validate() which is
indeed called and action errors is set when name is
null, but it just not displayed on the jsp.
The flow is, I click a menu item, which pass a
parameter 'Prepare' to a LookupDispatchAction. But
before that the Validate() is called and suppose to
return back with erros and then display the Tiles
right ?
Here is the validate():
ActionErrors errors = null;
String parameter = request.getParameter (method);
if (parameter == null || !
parameter.equalsIgnoreCase(prepare)) {
if ((name == null) || (name.length() 1)) {
errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(errors.required, Template name));
}
}
return errors;

Struts messages are not displayed in JSP
Hi,
I gies a strange problem, the messages are not
displayed. here is the code in my Action:
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage (templates List error));
saveMessages (request, messages);
In JSP:
font color=blue size=2
logic:messagesPresent message=true
html:messages id=messages message=true
lic:out value=${messages}//li
/html:messagesbr
/logic:messagesPresent
/font
however, the messages are not displayed when the code
is indeed executed.
Instead, I saw error in log file:
javax.servlet.jsp.JspException: ServletException in
'/WEB-INF/tiles/DisplayTemplate.jsp': Cannot find bean
messages in any scope
..
I thought the 'messgaes' is already in request scope.
And more strange, I also find the error message in log

Re: duplication of codes in different Action class
so JSP1 should be associated with another Action, which fetch data from DB and setAttribute in request or session. You should make your Action not the JSP1 available to the user. --- Sebastian Ho [EMAIL PROTECTED] wrote: Hi Scenario : 1. User submits form in JSP1 which Action1 saves to database. 2. Action1 set Form1 into session. 3. Action1 forwards to JSP1 again, which is suppose to display newly added form with other forms previously added. How do I make JSP1 to get values from database BEFORE JSP1 displays and set them into session? I suppose I have to do this in Action1 but for the first submission of form1, Action1 is not called yet by JSP1. From my analysis, there will be situation where there will be multiple input sources into a particular JSP. That means I need to have my 'update from database and set in session' codes in all the Action classes that forwards to JSP1? In another words, how do I call the update method in Action1 from Action2 before forwarding to the JSP which display my updated data. This is duplication of codes and inefficient to me. There must be a better way to do this in Struts. My question might be confusing..I am trying my best. Tell me if its unclear.

workflow violation handling in Struts Workflow Extension
Hi,
Got a problem, no idea what's wrong:
I have defined a violation handler:
---
action path=/admin/OrgWorkflowViolation
type=net.canal.admin.action.OrgWorkflowViolationAction
forward name=success path=.createOrgDef/
/action
---
the code works fine when I first time click somewhere
outside of the current running workflow. However, when
I click that outside link again, the Violation handler
is not being invoked anymore.
what should I do ?
The handler is veru simple:
--
if (null != WorkflowUtils.getNextStateViolationAction
(request)) {
ActionErrors errors=new ActionErrors ();
errors.add (violation, new ActionError
(error.workflow.violation));
saveErrors (request, errors);
}
return mapping.findForward (success);
---
Is it because the handler goes to a Tiles definition
so the current workflow state is lost ?
How do I go back to the current workflow phase after
handling the violation ?
thanks !
lixin

mutable variable in ActionForm is always reset to ture ?
Hi,
Could not figure out why the mutable variable is
always reset to true. Here is the snipet of my session
scoped ActionForm:
..
private boolean mutable = true;
public void setMutable(boolean mutable) {
this.mutable = mutable;
}
public boolean isMutable() {
return this.mutable;
}
public void reset(ActionMapping mapping,
HttpServletRequest request) {
if (isMutable()) {
.
}
}
In my prepareAction() class, i set it to false:
myForm.setMutable (false);
mapping.findMapping (success);
The prepareAction is defined in struts-config as:
action path=/admin/StartNewOrgWorkflow
type=net.canal.admin.action.PrepareOrgAction
forward name=success path=.createOrgDef/
/action
---
In my JSP file:
html:form action=/admin/OrgAction
..
/html:form
I suspect that the mutable variable is reset when
rendering the JSP file. But I do not know why.
and if it is true, how do I disable this so 'mutable'
will not be reset ?
many thanks !

Remember reset is always called before the ActionForm is populated with your values. If you are setting mutable to false in your action, then on the page you forward to you should see it as false.

html:reset does not clear all on the page ?

RE: best practice: how to handle two related jsp pages, with one having an ArrayList, the other input details
solution 1. persisting data may cause some problems, for example performance, as users may need to create a few detail objects. I prefer to keep these objects in View and provide a 'Done' button, which will then let Action to do the persistence. Another problem is that in my Use Case, the detail objects are associated to the parent object, which might not be persisted at this moment (because we go to B.JSP before saving data in A.JSP). So i can not persist detail object first. some work needed to solve these. solution 2. I am not sure if Struts Workflow extension is a good choice.

Re: best practice: how to handle two related jsp pages, with one having an ArrayList, the other input details
thanks. i saw some discussion earlier (search for request against session). It seems that people recommond not to use session scope forms. so out of these three, which is my best choice then: - Struts workflow extension - hidden field - session scope form many thanks ! --- Erik Weber [EMAIL PROTECTED] wrote: Session scoped forms are one of my favorite things about Struts. Seems like you have a situation for them. Make sure you keep all session-scoped form fields Serializable or mark them as transient if they are not. Clever implementations of ActionForm.reset can make memory management easier. The complication is simply that you might hold on to references to objects that should have been garbage once processing is complete. If you don't use session scoped forms, you will probably have to manage objects using session scope one way or another, unless you somehow use hidden variables to specify running objects that get recreated for each request.

best practice: how to handle two related jsp pages, with one having an ArrayList, the other input details
Hi, How should I handle this: I have 2 jsp, in a.JSP, I need to display an ArrayList. When users click 'Add', B.JSP is displayed which allows users to fill in the details of a new object. When users click 'Done', I need to return back to A.JSP, display the newly added object, and ArrayList should be updated as well. What do I need to do to support this ? thank you very much li xin __ Do you Yahoo!? New and Improved Yahoo!

Re: Struts, checkbox and optionally displaytag
thanks !

Hi !
From your question, I guess that you need a multiple
of checkboxes, so
you need html:multibox instead of html:checkbox
for your reference:
http://struts.apache.org/userGuide/struts-html.html#multibox
and a wonderful example:
http://j2ee.lagnada.com/struts/multibox-example1.htm
you would need an action form, which contains 2
arrays (normally they
would be String array)
eg. an Action form called FrmMultiBox with
properties :
String [] options; String[] selected;
options[] is holding the options of the checkboxes
that user going to select
selected[] would be populated by Struts after form
submission, value
of selected[] is the value of checked checkboxes.
so if options = new String {1, 2, 3} (you can
made them final or
load the values from another Action dynamically from
somewhere else)
in your JSP:
struts-logic:iterate id=_bean name=FrmMultiBox
property=options
struts-html:multibox
property=selected
struts-bean:write
name=_bean/
/struts-html:multibox
struts-bean:write name=_bean/
/struts-logic:iterate
if user check 1 and 3 then selected[] would
contains 1 and 3
(Thanks Struts !)
and don't forget the formal getter and setter method
of your Action form
Hope this help
Regards

[OT] How to get Role/Group info only in JAAS client/tagish package
Hi, A bit OT question: how to get the Role/Group info only in JASS client - I am using Tagish package but I guess it is common. In my login.java, I use: ~~~ lc = new LoginContext(); lc.login(); Set p = lc.getSubject().getPrincipals(); ~~~ However, the getPrincipals() returns all the principals associated with the Subjet, including user name and Group in terms of Tagish implementation - I think it is common for JAAS implementation. Is there a way to retrieve the Group/Role names only ? thanks ! li xin __ Do you Yahoo!? New and Improved Yahoo!
