Re: [DESIGN] struts dialog / wizard
You can also have a look at easy wizard http://superinterface.com/easywizard.htm ~madhav On 2/26/07, Tom Schneider [EMAIL PROTECTED] wrote: Mark Menard has done some work in this area for struts2: http://www.vitarara.org/cms/node/84 For webwork I implemented something similar called a model repository. The problem that's being solved is that when the domain model reaches a certain complexity, using the null instantiation feature and reading the model from the database again fail to work. The basic idea of the model repository was to save off the domain model somewhere (e.g. serial to a hidden field on the client, in an ehcache cache, in the session) before you go to the edit screen. When the data is posted back, before the parameter interceptor runs, you restore the model. This allows you to set the parameters back onto exactly the same model you edited. I like the idea of expanding the model repository idea to include the concept of conversation scope, but I don't want to loose simplicity of model repository. I'll probably create a plugin at some point to provide this functionality. Finally, there's also the scope interceptor that Don wrote that is still in the sandbox. Of course, all of this is for struts 2, so it doesn't do you any good for 1.4. :o) Paul Benedict wrote: How often do people develop wizards with Struts?

A review page which allow user to 'amend' sections (eg button to navigate back to that page) 5.

Re: struts tiles and validator framework
Let me elaborate my problem and the reason i have posted this to this list: I am using tiles with JSF. So i have just one layout.jsp. This file has the form tag and other JSP's just get inserted into the respective place holders. All of this works just fine. The problem comes when i am trying to use Struts client side validator framework along with the combination of tiles + JSF. In the validator framework - validation.xml file will require a form name and then all the fields and their respective validations. Will this mean that if there are 40 different forms that use the same layout tile will need to have fields uniquely named? I thought this was a big ask and therefore wanted to know how tiles and struts validator framework work together. Thanks for the reply. ~madhav On 11/7/06, Antonio Petrelli [EMAIL PROTECTED] wrote: Madhav Bhargava ha scritto: Since i am using struts tiles there is always going to be one form.

Probably you wanted to say that you have one form and the fields of that form is spread across different JSP pages, right? In this case probably you have to create a big big ActionForm that contains all fields, or create one ActionForm for each resulting page.

Hi All, I am using struts tiles for laying out all the pages. I am wondering how i can use struts client validator framework with struts tiles.

Re: [JAVA]Converting a string to date
There are many ways you can do it:
One way is using Apache BeanUtils with Converters registered to it. This way
automatic conversions can happen
Again it depends on what date you want to convert- current date, arbitrary
date.
You can just go ahead and use SimpleDateFormat's format/parse methods.

Re: Communicate between two struts apps
From your original mail the entire concept of having 2 war files bundled in one EAR file is a bit strange. You can totally avoid this by using different struts-config files and SwitchActions in struts.

Re: Stopping Double Submits via mutex
Consider a scenario of a clustered environment where there are multiple servers handling requests from an application. On each of these servers session object will be replicated. This means that the same request can go more than once. Shouldn't this solution fail then? ~madhav On 6/21/06, Paul Benedict [EMAIL PROTECTED] wrote: I've read many different techniques to stopping double submits, but one technique unfamiliar to me was described inside the Spring Framework. http://www.springframework.org/docs/api/org/springframework/web/util/HttpSessionMutexListener.html It did not occur to me to lock the session to make sure that, within a user's dialog with the server, only one request from a session makes it through. Now read that carefully: not one user, but one request from one user. So 1000 different threads can be running, but locking the session will ensure each is from a unique session. However, this class exists because some application servers do not guarantee that the same HttpSession object instance is re-used between requests. But the application server does need to guarantee the same object instance with the session... So Spring provides this class (nothing but a marker interface) if you want to head down this road. What do people think of locking the session via a session object? I like it, but I haven't implemented it -- but I want to use it if the feedback is good.

Re: ActionErrors not being displayed in jsp
Provide the following:
1. Action form code - complete
2. JSP snippet that you are using to print the messages
Alternatively postpone the validation till the action class. In the action
class check for user name and password and if there is a problem then set
the errors as:
ActionErrors errMessages = new ActionErrors();
errMessages.add(something, new ActionMessage(some.key);
saveErrors(request, errMessages);
and then forward the control to the same JSP where the error occurred.

Re: Stopping Double Submits via mutex
For a single JVM this is a nice way to handle multipel submits. But then a solution should never be limited to one JVM and if it has problems when multiple JVM;s come into the picture then it should re-thought upon. I would rather not go for such a solution even though it is a good solution for a single JVM. On 6/21/06, Paul Benedict [EMAIL PROTECTED] wrote: Yes - of course it would.

Now read that carefully: not one user, but one request from one user. So 1000 different threads can be running, but locking the session will ensure each is from a unique session. However, this class exists because some application servers do not guarantee that the same HttpSession object instance is re-used between requests. But the application server does need to guarantee the same object instance with the session... So Spring provides this class (nothing but a marker interface) if you want to head down this road. What do people think of locking the session via a session object? I like it, but I haven't implemented it -- but I want to use it if the feedback is good.

Re: ActionErrors not being displayed in jsp
If you give validate=true then you need to give input parameter in the
struts-config as well. One more thing - in your JSP try using the following
code:
logic:messagesPresent
html:messages id=errorMess
bean:write name=errorMess/
/html:messages id=errorMess
/logic:messagesPresent
If you have HTML tags as part of the messages in
ApplicationResources.properties then you will have to add - filter = false
to the bean:write tag. This will allow the HTML to be rendered properly, ie
it will not escape those HTML characters.

Re: struts validation problem
As a quick fix i changed the validator-rules.xml file. I added the
following:
*if (field == undefined) {*
* isValid = true;*
} else if {
}
I did this for required and mask rules. This solved the problem for me.
Thanks for your response. Moreover with the version of validator framework i
am using i doubt there is *validwhen* available. I need to double check
that.

The validation framework has no way to know the difference between 'the
control wasn't present on the page' and 'no value was submitted for the
control' so no, there's no way to tell it to only apply a validation
when the control is 'there'.
One possibility would be to express your validation constraints with
validwhen and use a hidden input or something to decide what rules to
apply.
But a better approach may be to leverage the validation framework's
'wizard' support. That allows you to specify a 'page' key on each
validation rule to control when it's applied. You would need to figure
out how to map the currently displayed tab to a page key for the
validator to look at, but that would probably give you a fairly clean
solution.

Struts and Ajax
Hi All, I have 2 drop downs in my JSP. One drop down gets populated based on the value selected in the other drop down. At present this is done using a Tag handler call. The control goes to a rendering action which then forwards the call to the JSP. From within the JSP the tag handler is invoked passing all the necessary arguments. This all works fine except that now the client wants to introduce Ajax so that a page refresh is avoided. I do not want to put any Html generating logic inside my action class. Is there any other elegant way in which i can generate the HTML for the drop down. I can very well write different methods to generate the HTML code and then call these methods from within my action class. But somehow this does not look very elegant to me. Any help will be appreciated. --Madhav -- When I tell the truth, it is not for the sake of convincing those who do not know it, but for the sake of defending those that do
Re: forwarding vs redirecting issue
another approach to handle session scoped objects is to create a filter that will be responsible to clean up any session scope objects when they are not needed. Alternatively you can also overwrite the RequestProcessor processPreprocess method and do session cleaning there as well. If you want struts to clean it for you then as stated above u can for session scoped form beans. --Madhav On 3/27/06, Michael Jouravlev [EMAIL PROTECTED] wrote: On 3/27/06, Chris Cheshire [EMAIL PROTECTED] wrote: Hi, I have a design issue based around form submission, protecting against resubmission etc. I have seen a couple of design guidelines that seem to conflict. 1) Use the session as little as possible (memory issues etc) 2) Use forwards where possible as requests can be passed along, with original information preserved, as well as speeding up communication. Now the only problem I face is after an action is complete, if I forward to a JSP, that action is open to resubmission when the user starts playing with the reload and back buttons on their browser. Redirects, because of the URL changing, can help protect against this. So the solution seems to be to place the beans required by the JSP page in displaying the result of the action in the session instead. So now there is an issue of when do the objects for the action that was just performed get removed from the session? Do I just put something in the start of each action to remove from the session all objects not associated with that action? I observe the common Struts pattern to front JSP pages with actions. I have a setup/render action that selects an appropriate JSP and forwards to it. I also have a submit action that handles the input. After submit action finished with input, it redirects to render action. So, I redirect from submit action to render action, but I forward from render action to a JSP page. You don't have to change URL in the address bar for redirect. Say, you have showItem.do?id=1234 action that forwards to JSP and shows item form. You update item and submit it to updateItem.do action. It updates the database or if errors found, it generates errors, sticks them into session and redirects to showItem.do?id=1234. Now you have the same URL in the browser again, with error messages in the form. Struts 1.2.6+ removes messages from session automatically after they were shown, but for anything else it is on you. Yes, controlling what is in session is a burden, and especially problematic if you allow a user to open several windows for one object. Then you cannot remove the object when the user returns to, say, a list of objects. This is a compromize. If you care about cleaner URLs and better user experience, use redirect and clean session yourself. Otherwise use Token object to prevent resubmits, but a user will still see POSTDATA message. Session-scoped data allows you to navigate to any action keeping application state, so you don't need to obey an artificial page flow. I think this is a benefit usage-wise. I prefer to use session-scoped ActionForms and to put everything related to an object into the form as nested properties. This seems easier to handle for me.

Hi All, I have a JSP page where on the select of a radio button some controls are disabled/enabled. The form bean associated with this JSP extends ValidatorForm. I have created rules in validation-xml for each of these controls which are there on the screen. One rule that is common to all the controls is -required.

If i need to do server side validations then how can i prevent the validator framework to validate controls which have been disabled. For client side validations i can just do some slight modifications in validation-rules.xml and get the behavior i want. For server side validations of this kind i can think of the following: 1. Override the apache class that provides the required behavior, then change validator-rules.xml to have the custom class instead. 2. override the validate method in the form bean and based on the request attributes get only errors for the controls that are enabled. - Somehow this method though simple fix does not appeal to me much. What can be the best way in which this can be acheived. One more thing: Does struts provide you a way in which you can check in a form bean whether a control was disabled.

Hi All,
I have a JSP page where on the select of a radio button some controls are
disabled/enabled. The form bean associated with this JSP extends
ValidatorForm. I have created rules in validation-xml for each of these
controls which are there on the screen. One rule that is common to all
the
controls is -required.
Depending on the selection of the radio button different methods in a
DispatchAction class are called. If i need to do server side validations
then how can i prevent the validator framework to validate controls which
have been disabled.
For client side validations i can just do some slight modifications in
validation-rules.xml and get the behavior i want.
For server side validations of this kind i can think of the following:
1. Override the apache class that provides the required behavior, then
change validator-rules.xml to have the custom class instead.
2. override the validate method in the form bean and based on the request
attributes get only errors for the controls that are enabled. - Somehow
this
method though simple fix does not appeal to me much.
What can be the best way in which this can be acheived.
One more thing:
Does struts provide you a way in which you can check in a form bean
whether
a control was disabled. The behavior that i observed is that if the
control
is disabled then the value in the form bean is null. Which is also the
case
when the user does not enter anything in the control.
