calling reset() method explicitly -- good or bad

Wed, 14 May 2008 04:15:14 MDT

Hi Ranchers,

We have a scenario wherein after submitting the form an update operation takes place in the database and the user is displayed with the same page.

But this time, the form values have to be reset and displayed afresh so that the user can enter further values and add it to the database.

Looking at this consequence, the reset() method in the ActionForm has to be called explicitly as it is called after the form is submitted and before the bean is populated with the request parameter values. That is very fine. But what we need is the form has to be reset during the page loading the next time.

Can we call the reset method explicitly in the Action class once our database...

about the validation

Tue, 13 May 2008 11:49:12 MDT

Hi there, I have some questions about the validation process.

I have this form to register a user, and it uses the the client-side validation framework and aldo the validate method of the form form server-side.

My question is, once the form validates that all fields are well formated, where do I do a validation for check if the username is already chosen, in the form or in the action?

if in the form: doesn't this breaks the mvc pattern? the form will know how the logic works

if in the action: how can I report the "login already in use" to the same page that has the form?

thanks

Picasa Web Uploader API & Struts

Tue, 13 May 2008 02:15:10 MDT

Has anybody tried integrating Picasa web Uploader API in your struts program. I am researching if we can integrate this as we need to get several photos uploaded in our system for users to manage and our current uploader is now limiting.

From what I have read here, I am finding it a bit difficult to figure out how would we integrate/implement remote service (the server side program) in our system. Has anybody tied something similar? Any pointers, help would be highly appreciated!

TIA,

DynaValidatorForm validation question.

Fri, 9 May 2008 14:56:59 MDT

If I create a DynaValidatorForm with multiple fields do I need to check server side that there are the same number of variables in each field?

For example say I did this:

type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="day" type="java.lang.String[]" size="0"/>
<form-property name="startTime" type="java.lang.String[]" size="0"/>
</form-bean>

Would I need something like this in my java code (to prevent hacking):

...

String[] days = (String[])form.get("day");
String[] startTime = (String[])form.get("startTime");

In Struts, Action class is a part of Controller or Model

Wed, 7 May 2008 22:14:54 MDT

Hi all,

In Struts, Action class comes under which part of Controller or Model ????

My opinion is , The Action Class is part of the Model and is a wrapper around the business logic. The purpose of Action Class is to translate the HttpServletRequest to the business logic.

And i got diffrent point from this site:
http://www.roseindia.net/struts/understandingstruts_action_class.shtml (http://www.roseindia.net/struts/understandingstruts_action_class.shtml)

Action class acts as wrapper around the business logic and provides an inteface to the application's Model layer. It acts as glue between the View and Model layer. It also transfers the data from the view layer to the specific business proce...

Connecting an applet to my struts data

Wed, 7 May 2008 16:04:53 MDT

I have a functioning struts web application.
I want to display some graphics based on data from my web application and my current thinking is to have an applet on a page which gets it's data from a servlet (or an struts action) and renders the appropriate images.

I have written the applet and have all my data in one object but connecting from the applet to a struts action just seems wrong and I can't seem to add another servlet into web.xml without the rest of the application breaking either (are you even really meant to use other servlets when you are using struts?).

Am I going about this all wrong? Is there an easier way?
Any help would be appreciated.

To highlight multiple selected values in listbox using struts

Tue, 6 May 2008 04:22:49 MDT

Hi..

I have a registration form where i am using a listbox where we can select multiple values.I am storing these values concatenating with commas(for eg. A,B,C).Now i have to update this registration form, so i have to retrieve these values and to hightlight the previously selected values.
I have the idea that first i have to retrieve that field from database and split the commas and then i have to write the code in the front end to display the values.
But in real time i m unable to display in front end.

Thanks
