Sub Actions in an Action class
Hi Craig and others, We plan to use coarse grained action classes in our application.Basically what we plan to is to do is combine add,update,delete operation to one Action class. We have two options . 1.Have 1Action class - 1 JSP - 1 Form Bean approach. This Action class will handle all operations/button of the particular page. Basically all button clicks. 2. Combine Add,update , delete etc of related data to a single action class. Which one of the two is the best approach. I have another question . 3.For aboove Options 1 and 2 we would need to handle sub actions in the Action class .We understand that DispatchAction can be used to handle this by using reflection.Is there a better approach to do this . Please give your valuable suggestions . Thanks and Regards, Bachan - Do you Yahoo!? U2 on LAUNCH - Exclusive medley videos from Greatest Hits CD

Re: Validator later rather than sooner?
That also sounds good.
Can you please tell how this entry would look like in validation.xml if we want to
validate based on action type.
formset
form name=logonForm
field property=value(username)
depends=minlength,maxlength
arg0 key=prompt.username/
arg1 key=${var:minlength} name=minlength
resource=false/
arg2 key=${var:maxlength} name=maxlength
resource=false/
var
var-namemaxlength/var-name
var-value16/var-value
/var
var
var-nameminlength/var-name
var-value3/var-value
/var
/field
/form

Instead of writing different action forms you can have different entries
in your struts config with the same Object type (i.e action form ).In this
was you can have different rule for each form using the validator framework.
Does this sound feasible.
Michael Lee wrote:Along the same thread, we are

We have broken most of our Action classes up into multiple classes. Before
we had one and used the property in the action mapping. That makes the
Action classes much more readable.
Problem is, these action classes still just use one ActionForm. This
ActionForm's validation method checks the parameter because the validation
for each page is different. This is starting to get large and unwieldy. I
don't want to have to create basically the same ActionForm for each Action
class when they are all mostly the same.
Question is, what is a clean way of breaking up all these validations?
Should I continue to check the action parameter and validate against it
within the same validation method for that one Action form? I was thinking
of extending the UserForm (the ActionForm in question) and just
implementing
the validation method. This way I could also get rid of the parameter in
the
action mapping of the struts-config.xml.

Is it general practice, or recommended, to develop a Struts application using the Action/ActionForm classes first (getting everything working properly) and later switch to the Validator classes, OR to use the Validator classes (implementing validation) right from the beginning?

Re: Only one DynaValidatorForm
Hi, In this case it would be better to do it this was. form-bean name=loginForm dynamic=true type=org.apache.struts.validator.DynaValidatorForm form-property name=userName type=java.lang.String initial= / form-property name=password type=java.lang.String initial= / /form-bean form-bean name=changePassword dynamic=true type=org.apache.struts.validator.DynaValidatorForm form-property name=userName type=java.lang.String initial= / form-property name=password type=java.lang.String initial= / form-property name=newPassword1 type=java.lang.String initial= / form-property name=newPassword2 type=java.lang.String initial= / /form-bean Any other suggestions ! Bachan Heligon Sandra [EMAIL PROTECTED] wrote: With DynaValidatorForm it is possible to use the same Form for multiple views (JSP page), isn't it ? How one indicates which parameter validated for a given page/action ? For example I defined the following form: type=org.apache.struts.validator.DynaValidatorForm initial= / initial= / initial= / initial= / For the page login.jsp only the fields userName and password are visible. The validator has to ignore the value of the other fields. For the page changePassword.jsp all the fields are visible. Is it possible to do that ?

RE: JavaScript Validation: MinLength MaxLength Functions Don't Work
Hi,
If you have noticed the validation would stil occur at the back end (java part).
If you want password also to be validated at front end change you
validator-rules.xml - javascript function validateMinLength
to the following code .
javascript![CDATA[
function validateMinLength(form) {
var bValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oMinLength = new minlength();
for (x in oMinLength) {
if (form[oMinLength[x][0]].type == 'text' ||
form[oMinLength[x][0]].type == 'password' ||
form[oMinLength[x][0]].type == 'textarea') {
var iMin = parseInt(oMinLength[x][2](minlength));
if (!(form[oMinLength[x][0]].value.length = iMin)) {
if (i == 0) {
focusField = form[oMinLength[x][0]];
}
fields[i++] = oMinLength[x][1];
bValid = false;
}
}
}
if (fields.length 0) {
focusField.focus();
alert(fields.join('\n'));
}
return bValid;
}]]
/javascript
This should work fine.Let me know.

JavaScript functions do NOT work on HTML
password fields. We just verified this. I totally agree with
Hajratwala. Struts should not impose this limitation on the developers.
It is the developers responsibility to control the amount of
security-related information returned to a user, not Struts. I go to
websites all the time where I get a message specifying the size limits for a
password. Does anyone know where the logic is implemented for ignoring the
max/min check on a password? Do others agree that Struts is outside it
boundaries by doing this? If so, maybe my team can submit a patch.

interesting ... sorry if this has been discussed to death already. If so,
i'll shut up. =)
Shouldn't the decision of displaying the validation be up to the application
developer?
For example, when changing a password, you would have a spot to enter old
new passwords, but would likely want to put some validation around the new
one (min 6 characters, etc). What would be wrong with displaying that info
to the user?

This has been explained before. I think it was by Ted. The reason has to do
with security. Specifying bouinds on the length of a password limits the
universe of potential passwords that a cracker would need to test. And of
course if he/she saw a message saying Password must be between 6 and 30
characters in length that would provide that information.

RE: struts Newbie - login screen
Struts can help yon in this .If you ever use a back button and go back you can make use of struts feature to take user to an error page . You have to make a call to saveToken() method in your ActionClasses. Thanks ! Bachan Sri Sankaran [EMAIL PROTECTED] wrote:This is one of the arguments that can go on for a long time. My thoughts on this subject are that the server can make no assumptions about the client other than what it knows. This philosophy permeates more than the 'back' button issue. It applies to validation, authentication etc. The server doesn't know that the user used the 'back' button. There are client-side technologies, such as JavaScript as your pointed out, that can aid in passing the server additional information. However, there could be other mitigating factors that makes using JavaScript or cookies not worth it in the long term. Think about the various sites on the web that authenticate the user. Majority of them don't do anything to prevent the user from re-logging in. Finally, if re-authenticating a user is such a hassle, one technique that isn't anathema in all situations is to trigger a new window to start your application upon user authentication.

Error Higlighting capability of Struts Tags and JSTL Usage
Hi, Does the input tags in struts have any inbuild error highlighting capability . What I mean is if the validate / any other method sets an error message with the key as the field name of a field , will the tag look into the ActionErrors object for each of the input fields and check whether the key is contained in the error object and do the following . 1. Give focus to the first error field even if the error there is a field given for the focus attribute in the form. 2. Give a different style background color/ text color to all the error filed. Also is it advisable to use struts tags /JSTL tags for tags like logic ,bean etc Thanks ! Bachan - Do you Yahoo!? Y! Web Hosting - Let the expert host your web site
