However, your JSPs will in all probability NOT be rendering markup for display to the user... they will probably generate some sort of data structure that your Swing client will use to update the view. Maybe XML for example. Your Swing app just makes HTTP requests to the app on the server as usual. I know this because about 3 years ago I was asked to do this... the project didn't go beyond proof-of-concept, but it was working just fine before it was aborted. Now, keep in mind that when you use JSPs, assuming you use Struts tags, you'll be giving that stuff up, or more precisely, you'll have to code it all yourself... if input validation fails for instance, you'll have to deal with redisplaying the entered values (if they were ever not visible that is).

tiles and forwards

Re: Validation not working for 'double' with Struts 1.2
this to work you need to define the property in your ActionForm as a String, not a Double. Hi , I have treid this but couldnt find any luck, now instead of a defaut value 0.0 in the case of 'Double' the invalid 'char/string' gets stored in the database. As if the validtion is not working at all for 'depends= double' I tried to extend 'ValidatiorActionForm' instead of 'ActionForm' since there is no '.js' like 'validateDouble.js' for 'double'. Then being a financial project I really dont want to change it to a 'String' data type from a 'Double' so that no precision is lost if I ever have to cast it to a 'Double' while implementing b.Logic in the future.. To be frank enough I started to look for a '.js' function so that I can do the validation for 'Double' in the client side itself. Thanking you all Antony -- View this message in context: http://www.nabble.com/Validation-not-working-for-%27double%27-with-Struts-1.2-t1754076.html#a4787921 Sent from the Struts - User forum at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

As Adam J. mentioned, it sounds like you're using a session-scoped
bean. Try overriding (if you haven't already) the reset() method of
your form bean and resetting the property:
public void reset( ActionMapping mapping, HttpServletRequest request )
{
this.values = new String[0];
}
If you're _not_ using a session bean (and are using a request-scoped one
instead), you'll _still_ want to do the above. Using this way in both
cases, values from the previous request are discarded. If the web
browser doesn't send any checkbox values over (because none are
checked), then this.values will be an empty array, which corresponds to
the very state of the submitted form's checkboxes (ie: none are checked).
The array of values in your formbean for an html:multibox are a list of
values of checked checkboxes. So...
1. Form bean looks like this:
this.values = { value1, value3, value5 };
2. Displayed form looks like this:
html:multibox property=valuesvalue1/html:multibox 1
html:multibox property=valuesvalue2/html:multibox 2
html:multibox property=valuesvalue3/html:multibox 3
html:multibox property=valuesvalue4/html:multibox 4
html:multibox property=valuesvalue5/html:multibox 5
3. HTML sent to browser looks like this:
input type=checkbox name=values value=value1 checked 1
input type=checkbox name=values value=value1 2
input type=checkbox name=values value=value1 checked 3
input type=checkbox name=values value=value1 4
input type=checkbox name=values value=value1 checked 5
4. User unchecks ALL checkboxes, and submits the form.
5. Struts calls reset() on your form
- Your reset() method sets this.values = new String[0]
6. Struts populates your form, and _doesn't touch values_, because
nothing is checked, so values remains an empty array.
Sound good?

Selecting and setting Bean Object from html:select
Hi,
I am trying to get an html:select with html:optionsCollection to set a
property in my ActionForm with the actuall bean that was selected rather
than the associated value:
// Bean class
public class Item
{
int id;
String name;
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}
// ActionForm
public class itemForm extends ActionForm
{
Item selectedItem;
ListItem allItems;
public Item getSelectedItem() { return selectedItem; }
public void setSelectedItem(Item selectedItem) { this.selectedItem =
selectedItem; }
public ListItem getAllItems() { ... }
}
// jsp page
html:select property=selectedItem
html:optionsCollection property=allItems label=name
value=id/
/html:select
Obviously this fails since it will try and call setSelectedItem with an
int value causing a argument type mismatch exception. Is there a way to
make it use the actual Item Bean that was selected or it is simpler for
me to just retrieve the id value and use this to match the selected bean
elsewhere?
Thanks in advance.

RE: best way to send parameters through more requests
Typically the best solution is to keep this data in the session. That is what the session is for. As I mentioned, the other option would be to encode the data using base64 encoding (or something similar) and store it in a single hidden field. What makes you so sure you have too much data in the session? Perhaps you could streamline some of the other data you store in the session or make sure you cleanup unneeded data. -Adam -Original Message- From: Emilia Ipate [mailto:[EMAIL PROTECTED] Sent: Friday, June 09, 2006 8:04 AM To: Struts Users Mailing List Subject: RE: best way to send parameters through more requests Using hidden fields is good, but what if you have like 4-5 request steps?

Re: best way to send parameters through more requests
One way can be to use the values in session and somehow explicitly delete these attributes after they have been used. Event listeners can I think help here. Just pump an event when you are done with. This should delete the session attributes. Any good patterns in this regard?? References? Using hidden fields is good, but what if you have like 4-5 request steps?

Re: tiles and forwards
Correct, i used the internal strutsAction:
org.apache.struts.actions.LocaleAction and the source could something like this,
which i found in the validator struts-example:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
// Extract attributes we will need
HttpSession session = request.getSession();
Locale locale = getLocale(request);
String language = null;
String country = null;
String page = null;
try {
language = (String)
PropertyUtils.getSimpleProperty(form, language);
country = (String)
PropertyUtils.getSimpleProperty(form, country);
page = (String)
PropertyUtils.getSimpleProperty(form, page);
} catch (Exception e) {
log.error(e.getMessage(), e);
}
if ((language != null language.length() 0)
(country != null country.length() 0)) {
locale = new java.util.Locale(language, country);
} else if (language != null language.length() 0) {
locale = new java.util.Locale(language, );

RE: best way to send parameters through more requests
Do not get into encoding and decodingas you might be aware that you can specify the charset at many places like web.xml, in javascript tag and also when you encode/decode in java.

RE: best way to send parameters through more requests
The thought here(base64 encode) was to store the data on the client. This would also be a large effort requiring all POST requests, making sure you always send the data in both directions, extra network etc. Got that, thanks for the explaination. Bottom line, storing state for a particular client is what the session is there for. Anything else will most likely cost more in development effort than upgrading hardware. I am working on a very big project (has about 3 requests a day)! A lot of the functionality are different settings that the user can make in a 4-5 steps request (in the last step the user can decide to cancel the entire operation or at step 3 he simply gets out of the step-by-step setting process). So I cannot just hold these objects in session forever, that's why I think a session mantaining functionality is required: 1. have a configuration file that specifies exactly what objects can be hold in session 2. for each object that can be hold in session, specify the url-patterns for which the object must still be in the session 3. have a filter that mantains the session accordingly Emilia -Original Message- From: Samere, Adam J [mailto:[EMAIL PROTECTED] Sent: vrijdag 9 juni 2006 15:20 To: Struts Users Mailing List Subject: RE: best way to send parameters through more requests The thought here(base64 encode) was to store the data on the client.

This application is used in the storeroom to allow a user to enter the stock they are taking out of the storeroom. Granted we could have people walk out with stock and not even enter it, but, if they do enter it, we want to be able to contact them and ask what they did with the stock. Did they put it back? Did they take and forget to checkout? Did they take it and the account they used come back as invalid? Then, the storekeeper can either complete the checkout or clear the shopping cart for the user. We have some indication available to our storekeepers that some activity has taken place and contact information to use to follow up with. I mean we are relieve them of the data entry they were doing. They just have a new job of following up on checkouts not performed. Our next step is to allow for ordering of items for delivery or pickup and using the shopping cart to build the pick list for the storekeepers. If this were a shopping cart for a web site, I can see where they would like it in session because then it is cleared when the session teminates and they don't have all this unneeded information in their db. For us the situation is different and we really need that information to make sure all information needed for a final transaction is captured. This is even more important when our pricing might change the next minute because a storekeeper is adding new stock received and price averaging is occuring. Hope this clarifies how we look at things. By the way, I work for a university and these storerooms are supplying student labs and researchers and we have some really strict stock control issues with chemicals and such.

Michael. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Right, Michael. Each individual item is stored by userID and unitID. Therefore, a user can have multiple carts depending on storeroom they are shopping in. The user can clear a cart any time prior to a successful checkout. Honor system on the user's part. The storekeeper can process, correct or clear a cart for his storeroom after speaking to the user by phone or email to determine where the stock is. Once a successful checkout has occured, the storekeeper is the only one who can return a stock item. Returns might be due to an incorrect quantity being entered by the user or they took the wrong stock to begin with. He will look up the invoice for the user in his storeroom, select the items from the invoi ce to insure he is crediting it at the price it was sold and give the user a copy of the completed storekeeper invoice showing the item was credited.

Re: Variable 'input' attribute in struts-config.xml
Hi Scott, this is how I would implemented it. What we have is a standard CRUD stuff for Entity object. There are two ways to navigate to Entity. Either you simply navigate to it and it renders itself according to its state, or you navigate to it with a certain command, like view or update or delete or create. The latter way is simpler and occurs more often and is easiter to understand and implement, so let's discuss that one. Say, you have a table with a rows, each row represents an Entity. You may click the row to pull Entity out. Say, each row has links like view, update or delete. There is also one link or button called create. To view, update or delete an entity, you call EntityAction with a corresponding command along with entity ID. To create an entity you call EntityAction without ID. See, EntityAction is a perfect candidate to be implemented with dispatch action, I suggest EventDispatchAction. If you call EntityAction with view command, the action loads existing entity and forwards to view_entity.jsp. I prefer to use session-scoped formbeans so I set Entity state in the form to view. If you prefer to use request-scoped beans, you can save Entity state in the hidden field in view_entity.jsp. Same thing with edit command, the action loads existing entity, sets state to edit and forwards to edit_entity.jsp. To create Entity, the action initializes formbean, sets state to create and forwards to create_entity.jsp. In fact, all these JSP pages may be actually one page, you just need to update the title and maybe to show/hide ID field. After you filled in the form, you call EntityAction with store command. It validates the input and then tries to update/store data. If input is not valid, the action checks the state field and forward to a JSP that corresponds to that state. The page will be displayed along with the errors. If data is saved successfully, you forward to your success page, which is probably the item list. Same with deletion, after delete event is served, you forward to success page. So, the only problem here is what happens if a user navigates to EntityAction without command parameter? This is up to you. If you use dispatch action, you would correlate commands with action methods. If no command is passed to the action, the execute() will be called instead of a specific method handler. Because there is no active Entity, you can either show No entity message or forward to some error page. If you prefer to use redirection instead of forwarding, then you would have to either save state on the server (this is what I do), or to pass all state info in redirected request. A combination of these approaches is to pass Entity ID and maybe mode ID (like updating or creating) in redirected request, and to store everything else in the session. As you may see, one dispatch action, one form bean and maybe even one JSP page is enough to serve all your commands. Michael. On 6/8/06, Scott Van Wart [EMAIL PROTECTED] wrote: Michael Jouravlev wrote: I suggest to look at your issue from another perspective. Do you really need the functionality you are asking for? First, a small clarification. There is no input page for an action, input attribute is poorly named, it should be called error or errorTarget, because Struts forwards to that location if input data does not validate. Your request is always sent to action/actionform. That might be it then... it might just be a matter of having to separate things out a little more. So let's say I had a page that edits an entity. I might call this edit_entity.jsp, with an EntityForm, and a SaveEntityAction. I found things got a little cumbersome in the .jsp, so I separated it out into a create_entity.jsp and edit_entity.jsp. These two forms submit to the same action. Obviously, they have a lot of code in common, but I thought of factoring that out into tags. Perhaps I should do the same thing to the action class (CreateEntityAction and UpdateEntityAction rather than all-encompassing SaveEntityAction; any code duplication can go into base classes or utility classes). The other side of this is that I also have a ShowEntityForm and ShowEntityAction. The action is mapped to /showEntity, and there are three forward mappings from there. Two are success-like forwards called create and edit, which forward to create_entity.jsp and edit_entity.jsp. The 3rd one, the failure forward's destination would depend on who called /showEntity in the first place. The ShowEntityForm has validation, to ensure the given entityId is a number, and the failure forward gets hit when the entityId can't be found in the database table. While I can break the failure out into multiple forwards, I can't do the same with input. So the question is, then, do I break up my ShowEntityX classes into things like NewEntityAction-create_entity.jsp-CreateEntityAction and EditEntityAction-edit_entity.jsp-UpdateEntityAction? It's starting to sound like a lot more classes, but if I'm on
Re: Variable 'input' attribute in struts-config.xml
What I would do is having an AvailableItems web resource with two states: no items (default) and items found. For no items it would render a search page, for items found it would render items list.

In our application, we start with a query page that allows entry of data for a query or has a link to create a new object. If they enter query information we go to a query action which generates a results jsp or returns them to the query jsp if no matchs are found. On the results page on each line displaying a item, we have 3 links that either show them the details for the item, allow them to update the item or delete the item. Links are displayed based on the role that the user might have. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Page does not refresh after action
Hi, I have a page with a bunch of orders, and each order has a Cancel button next to it and the status text of that order. When I cancel a particular order, the appropriate action is called, the order is canceled and the action then returns to the same page. I can see the page being reloaded (thru the status bar on the browser), but the status text (which should now say Canceled) for the order remains the same until I hit Refresh again (or come back to the page by navigating to it). Is it possible that the browser is caching the status text and how can I overcome this problem?

Re: Thank you to the list.
Hi Albert, Nicely done; I'm sure the developers appreciate it. I'm in the same situation as you. What I like the most about this list is everyone has a positive attitude towards answering questions. I'm sure it's tough to be a part of the brains behind a project, to know the code intimately, and to have the most basic questions asked time and again by a countless numbers of new users. I also like it when the developers (I'm assuming they're Struts developers from the discussion content :) get into discussions about underlying implementations; it gives me a great deal of insight into how the tools are written. It can be a little discouraging for a developer to pick up a library like Struts, have questions, and receive an RTFM-type answer. I've yet to see such an answer on this list, and appreciate the practical usages and best practices stressed in a lot of the list replies. Keep coding Albert; knowledge received is knowledge to be shared :). - Scott Albert L.

Re: tiles and forwards
Antonio Petrelli ha scritto: Can you post the code of your action? At least the part when you return the forward in the execute method? I have a suspect. Now I use my own LocaleAction (extends Action !) with the following returns : if (page != null page.length() 0) return new ActionForward(page); else return mapping.findForward(success); and this works and no exception occurs, if the pageAttribute not exist. The next is, how can I get the actual tilesDefintion in the locale.jsp (perhaps by jstl and EL) or in the LocaleAction.java ? This is important, because the tile locale.jsp do the languageSwitch and is part of every page. So, after the languageSwitch I have to forward to the actual tilesDefinition (to stay in the page). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
