Should Action or ActionForm be accessing business delegates?
The reading I've done suggested that one of the Action class's primary responsibilities was to access the business layer. Then today I was looking at the core j2ee patterns and it showed the View Helper accessing the business layer. I associated (maybe mistakenly) the View Helper pattern with the ActionForm and was then wondering if I should design our ActionForm's to have direct access to the business layer. Thoughts? Thanks, Brian Barnett

RE: Validator and DispatchAction
Set validate=false in your action mapping in struts-config. This tells the struts framework not to call validate. Then in your action class you can call validate where appropriate, i.e., the *save* method. -Original Message- From: Renato Romano [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 18, 2004 6:43 AM To: 'Struts Users Mailing List' Subject: Validator and DispatchAction I'm quite new to the validator framework, and was trying to figure out how to use it. My situation is: 1) I want to perform server side validation, and so I made my form extend ValidatorForm; 2) the action that processes my form is a DispatchAction, so I have methods like edit, save list, all associated with the same form; 3) I call http://blabla/myapp/myAction.do?methodName=edit to have the app present me with an empty form; 4) When processing this action, struts allocates the form and calls the validate method, which of course causes validation errors to be produced, and the request to be forwarded to the input element of my action, which, as usual, is the same jsp which contains the form; 5) since the page finds some errors (the form is empty!!) they are shown by the html:errors/ tag. The only think I can imagine is to have a separate action in struts-config, which takes no form and simply redirects control to the jsp page which shows the (html) form. This should avoid Struts from calling the validate method, and hence html:errors/ should show nothing. Of course this would change a bit the logic we already placed in the application actions: for example action.do?methodName=edit in our architecture should present an empty form, while action.do?m=editid=88 should fill the form with the properties of the object with id 88, and then forward to the same jsp page, which then shows that object ready to be modified. If my above consideration is correct I should define two separate actions in struts-config, and let the links be something like newObject.do (for the presentation of an empty form) and unchanged for the loading of an object. Is all this correct ?Are there alternative approaches? Should I quit server side validation and only use client-side (which does not suffer from this problem)? Any help is very appreciated.

RE: Role based access?
Another option I believe is to let the j2ee container handle security. I'm not up on all the jargon, but I'm using roles and form-based security.

RE: [OT] - Request against Session
When a browser first requests a page from a web server, the session is created, so as Wendy said, it's always there. The creation of the session has nothing to do with whether the user is authenticated/logged in or not. This is the way I understand it. If you are set on using hidden variables here is a bit of info: Using a hidden variable on a jsp page in Struts is pretty straightforward. First, you add a variable to the formbean being used on the page with corresponding setter/getter methods. Then in your jsp page, put something like this in your form: html:hidden name=myFormBean property=myHiddenRegistrationValue/ When the form is submitted, Struts finds a myFormBean object in the appropriate scope (or instantiates a new one) and stuffs the value of the hidden variable into myFormBean (using setter method). In other words, it treats it like all the other form variables by calling the setter methods of the formbean. Then in your action class, you can reference the variable using the getter method of your formbean. For multiple pages, you'd have to follow the above guidelines on each page and most likely programmatically call the setter method in your action classes between page calls. Don't use getParameter() to try to get hidden form variables. getParameter() looks for parameters appended to the request URL -- http://www.myhost.com/do/myAction?param1=1param2=2. getParameter() will give you access to param1 and param2. You can also very easily access the session variables in your action class like this: request.getSession().getAttribute(sessionVarName) Brian Barnett -Original Message- From: Pani R [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 11, 2004 2:02 PM To: Struts Users Mailing List Subject: RE: [OT] - Request against Session Thanks for the advice Wendy. I may end up storing all the values in the Session. But, on the other side, how would I store it in the hidden form variable. I think if I store it in my hidden variable, then its available to me in the action class via getParameter() which will return me a String object against my User Defined Object.

If you're going to need something across requests, you can either jump through hoops and put it in hidden form elements, etc., or just stuff it in the session. I tend to treate memory and disk space as infinite resources, which may not scale, but works for my purposes. My vote is to put your values in the session and don't look back.

RE: Validation problem
The Struts Validator provides a mechanism to deal with Cancel buttons. A flag is set in the onclick method for the cancel button in the jsp page. The validate methods check this flag and if it is set, they skip validation and just return true. html:cancel onclick=bCancel=true; If you're not using the Struts Validator, maybe you could try mimicking this behavior in your validate method ??

I have a form the has three html:submit buttons -- Update, Cancel and Delete. I am using a LookupDispatchAction and an ActionForm with the validation in the validate() method. Under normal conditions everything works fine..But when a user clicks Update with invalid data on the form, the validate method catches the bad data and returns the proper error message. If the user then decides to click Cancel (without changing the invalid data), the validate() method is still called and the user is returned the same error. One thing that I might be able to do is to somehow find out what button was clicked in the validate() method...??

RE: form validation question
Your orderForm does extend ValidatorForm instead of ActionForm right? The struts validator plug-in relies on your forms extending ValidatorForm in order to do server-side validations. Out of curiosity, you may want to see if client-side validation works first. html:form action=SubmitOrder.do onsubmit=return validateOrderForm(this) ... /html:form validator:javascript formName=orderForm/ When the submit button is pressed, if the required field is empty, you should get a message window indicating the field is required.

RE: Problems Redirecting To Input Page After Vaildation Fails
Personally, I would try to use the same page for add, update and delete, which would solve this problem. If this is not an option for you, you may have to deal with it in ClientAction. Remove the input attribute from your action mapping, add validate=false, and add a couple of forward elements. action path=/clientaction type=ie.sentenial.application.actions.ClientAction name=clientForm scope=request validate=false attribute=clientForm forward name=AddValidationError path=/pages/addClient.jsp/ forward name=UpdateValidationError path=/pages/updateClient.jsp/ /action Then inside ClientAction, programmatically call the validate() method, since the framework won't be calling it for us (validate=false).
