Re: How to programmatically send a form (Dev WO)

Hi James, this looks like what I need:)
I'll try to implement that right now.

Thanks a lot

Xavier


Xavier,

I wrote a similar app a couple years ago for PayFlowLink using WORedirect:

public WOComponent sendToVerisign() {
WORedirect nextPage;
nextPage = new WORedirect(context());
nextPage.setUrl (yourTargetUrlAsString());  <-- use your banks method here
return nextPage;
}

I created a component that extended WOComponent, which contained a WOActiveImage linked to the above method.  I placed mine on a 'verify order' page, and it worked great.

The return side of the transaction poses a bigger problem if you are running multiple instances of your app.  If your bank makes a return-post to a directAction, WO will probably create a new session for your user.  To deal with this, I passed the session and instance number to verisign, which in turn is part of their return post.  The return-post directAction I provided was to a separate app, that parsed the return-post and redirected the user to the original instance & session much in the same way as the above method.

If you are running a single instance, then it is a simple DA.

Hope that helps,
Jim :)

In fact I "just" need to generate a "signed" form then the submit  
button should do a couple thing on my side, and send my user to the  
bank server.
Then, depending on the transaction, the bank will call a direct  
action on my side to activate a sort of recipe.
So basically I don't really need to "wait" for something, I send the  
form to the bank then if something happens (a call to my direct  
action), then I'll update the order to either true or false.
So actually I'm pretty "stop" about how to write a method that would  
provide "send my form using http and display the bank site", but  
maybe just having a url in the action field of the form would lead to  
this behavior and linking an action to the submit button to do the  
stuff I need on my side (like saving the order).
Would it work to have both something for the action of the form and  
an action bind to the submit button?
In this case, I'm not sure I could handle the following case:
bug on my side, but the user get send to the bank account anyway.

In fact after thinking about it, I'm pretty sure I shouldn't provide  
the form inside the page, but only generate the post action when the  
submit button is clicked...I'm not sure I'm clear;)

Usually your provider will give you instructions specific to  
sending a user to their credit card page where the user fills in  
the details and processes the payment.
They do (more below)

For example if you go to this page on this site and right-click on  
the actual form and open in a new window, you will see that the  
form is really a page on the credit card provider's site shown  
inside a html frame on the originating site.
http://www.loacademy.com/OrderProduct.asp (not my site ... I don't  
do asp dev!)
I cannot use frame, we've got important concerned about  
accessibility, and frame are just... horrible;)
But I don't need to handle the bank part, only send my user there  
using a "post" form, and eventually answer to a call to a direct action.

Did your bank provider provide you with a development kit/manual?
Yes they do provide me with a Java kit containing the method that  
would generate the form as a string....but I don't know what to do  
with this string:(
