Actions Chaining question

[javaspring]

Hi all,

I'm working on a e-commerce application using Spring 1.2.8 framework.
I need to prevent the user from violating the normal process of application execution. For example, if someone is buying an article the following process should be respected : 1-adding articles to the cart -> 2-validating cart -> 3-payment -> 4-payment confirmation...etc

The problem is that users may access directly one of this process steps violating the normal process order.

Is there any solution to solve this problem ?

thanks,

The AbstractWizardFormController may be what you want

Maybe a little more information of your implementation is needed. Are those 4 steps implemented as own controllers? I guess so? One solution indeed is the AbstractWizardFormController or maybe you should just check the values in your command object that holds the user's data (selected products etc.). If needed infomation is missing, throw an error and redirect user elsewhere.

This is just my quick solution, since I don't know any details of your project

Hi,

Unfortunatelly, I'm using separate controllers (SimpleFormControllers and Abstractcontroller) in each step. Each controller processes an associated form and redirects to the next form.

I tried to code an interceptor and an automata that checks wether the normal order of the steps is respected or not, but I'm wondering if there is another elegant solution.

Depending on your needs there are 2 solutions

• AbstractWizardFormController
• Spring Web Flow

For just a shopping card Spring Web Flow might be a bit over the top. But I would at least strongly suggest you take a look at the AbstractWizardFormController.
