Re: Checkling Security
You can use the standard Servlet authorization/authentication mechanism, or use a Servlet filter, or use a custom ActionMappings class or common base Action subclass if you're bent on handling it within Struts. -Adam chamal desilva wrote: Hi, How should we test wether a user has permission for an action.

Re: How to set size of submit button
Frank and Eddie are right about not being able to read the css property
unless you have set it ahead of time. The javascript Element Object
(from which buttons etc are derived) has properties called clientWidth
and clientHeight. This will give you the width and height of the element
in pixels as rendered on the client. Hopefully that helps!
document.getElementById('b').clientWidth

Frank,
I don't think you could extract the width from the control's style
unless you'd set it. I'd have to agree with you on that one. Isn't
there a property on the control (width?) you could determine the width
from? Maybe I answered too quick and should have done some research
first. I was thinking I had done something similar before, but as I
dig deeper into my memory I realize that it was the height of an
iframe I set, and that was based off the contained document's height
(scroll height or some such thing).
I suppose it seemed intuitive to me that the button should have a
width. I'll dig into my JavaScript book while at the office tomorrow
and see if there isn't a property that a person can determine the
width of a button with. There's got to be a way to do it. I'm
curious now, too! I have been wrong before though.
I'll try to pop-in at lunch and drop my findings ;-)

Would that even work Eddie? I seem to remember that if you didn't
explicitly set the width of an element yourself, you can't retrieve
it. Indeed, this quick test:
..results in a blank alert in both IE and FF.
This only matters of course if you have to make all the buttons the
same width dynamically, but now I'm just curious! Is there a way to
do it I wonder?

Re: Organizing action classes
Depending on what version of Struts you are using, you could check out org.apache.struts.actions.DispatchAction and it's subclasses. For the sake of maintainability and readability though I generally prefer to keep a 1 to 1 between action subclasses and path mappings, factoring common functionality into base action classes or helpers. Just personal opinion though. -Adam chamal desilva wrote: Hi, I have few action mapings. /get_admin_tasks /add_task /ass_user etc. /get_add_data /save_customer_data /save_account_data etc. Is it necessary to write Action classes for each of these actions or can we group several actions in to one Action class. What is the best way to organize actions in to action classes. Thanking You, Chamal. __ Do You Yahoo!? Tired of spam? Yahoo!

No? Not sure I understand this - to my knowledge the framework doesn't add any "global" messages. Also how does implementing a key of "org.apache.struts.action.GLOBAL_MESSAGE" differ from implementing your "own solution" of another key value - except that the other key value doesn't have to be as cumbersome? Whatever you and "other developers" do you have to agree to handshake on these things - whether its with this value of the key or your own. My sense of reading your comment is that you think that Struts is providing you with some sort of solution - when in reality it isn't actually doing anything wrt to this constant. Niall getActionMessages in org.apache.struts.taglib.TagUtils converts String and String[] to ActionMessage instances and stores them under ActionMessages.GLOBAL_MESSAGE. My reason for jumping in on this thread was that it was suggested to use the literal key org.apache.struts.action.GLOBAL_MESSAGE in the messages tag, where my general intuition tells me it is a bad idea to resolve the value of a constant inside a 3rd party framework and plug it in as literal text. What happens to everyone who took this approach if the key is ever changed, or as Joe mentioned deprecated/removed? It just adds up to another task during a future upgrade. Your solution of storing the messages under your own less cumbersome key is probably the best one, but with the ActionMessages.GLOBAL_MESSAGE constant out there many people will continue to use it when manually creating and storing messages, forcing the use of either scriptlet expressions, direct reference to the literal, or additional code maintenance in order to achieve the relatively simple concept of "get me all the messages stored under the GLOBAL_MESSAGE key, but none of the others". -Adam >> Joe >> >> -- >> Joe Germuska >> [EMAIL PROTECTED] * http://blog.germuska.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: displaying ActionMessages.GLOBAL_MESSAGE messages only
I agree that scriptlets are undesirable, but IMHO when compared with the consequences of having to track down and modify the key in every page that referenced it directly it's the lesser of two evils. So the goal of the new attribute on the tags would be to display/test for only messages stored under the globals key? Which takes precedence then, name/property or global?

Re: How to pass request parameters through a waiting page?
Starki, I assume you have a form or a link on a page that the user submits. Here is a sample of a simple link with parameters: Do Something I'm making use of the set tag from the JSTL core tag library to set the parameters into a HashMap, then linking the the action. The Action subclass I'm using is just a ForwardAction, which forwards to "wait.jsp" From struts-config.xml: Then, in the wait.jsp page, I pull the request parameters from the request instance (I'm using the runtime expression value version of the set tag here) and store them in a page scope variable called "parameters". Then I just set the url in the content attribute of the meta http-equiv tag to the value rendered by the html rewrite tag, passing the parameters map. scope="page"/> "> Untitled Document Hope that helps! starki78 wrote: Hi Adam, an example would be great!

Re: Ajax and MVC pattern
I've recently used AJAX in some existing Struts applications making use of AjaxTags http://ajaxtags.sourceforge.net/. The Struts controller is still very much applicable, in that the Ajax requests are made to struts action urls, the action subclasses then delegate processing to business objects in the same way as we're used to, and finally forward to a JSP for generating the output. The major difference is the JSP's generate XML responses, rather than HTML/XHTML. Essentially they return either a page fragment or an XML item list of some type which is then parsed and stuffed into the client side DOM using javascript for immediate display. Adam Hardy wrote: I have only a small knowledge of the Ajax frameworks out there and I am trying to work out how much an Ajax app would depend on Struts. I assume the view in an Ajax app is handled at the initial request by a JSP with HTML and that afterwards every request from the browser is XHR, ideally broken down on a per-data-item/list basis. The view HTML is from there on in handled by Ajax. In that case the Controller part of MVC would be managed entirely client-side. Therefore all that struts would have to offer the app would be Validator and perhaps a couple of other services. Or am I totally wrong? Can struts offer the ability to manage the Controller part of the app in such a way that the project could have two views - one in Ajax and one in JSPs? I'm aware of much discussion of enhancing Struts Action 2 to facilitate Ajax development. It seems I'm missing something though. Can anyone elaborate a little on what it is facilitating?
