Start a form from JSP

[dvanhussel]

Hi,

I'm implementing a connection with Ogone (a payment provider). This service needs a webpage it can call to update paymentstatus. This can be days later then when the payment was started by the user. The status of the payment is send in several url parameters.

I want this webpage to be an Ebase form. But unfortunately it doesn't work. That's because Ogone sends 1 request (post or get) to the page. It doesn't handle the default page reload of Ebase checking the browser capability's.
So, the script that is defined as before form script, is not run.

Is there a way to prevent this reload from happening?

Or is it possible to start a form from a JSP page without user interaction, like from the Ebase Scheduler? Then Ogone calls the JSP, which collect's the url parameters and then invokes the form to handle these parameters.

I could not find this in the documentation of Ebase.

Of course, any other solution for this problem is welcome as well

Regards,

David

David,

I guess the best solution would be to set up an Integration Service and have Ogone call this. But this might not be an option.

Other alternatives are:

1. Disable the browser check mechanism (Ufs.skipBrowserAttributesCheck= true in UFSSetup.properties). Though then the system won't be able to detect clients with Javascript disabled, and it won't know the browser type, which can give problems with IE6/7 and menus. To get around these problems, you could set up a separate web app with this option and just use it for these Ogone calls.

2. You could use the batch system as a means of running a form (just the before form event) from a JSP. This doesn't support tables, and it's an old piece of functionality but it should work. To get this working, you would need to create an XML document in your JSP containing the form name and any input data, and then call the batch system servlet. See batch documentation (under Advanced Topics on the documentation main index page).

3. Save the data in your JSP to the database. Then have a scheduled form that wakes up at fixed intervals and processes it.

I think I would prefer option 1 or 3.

Hi David,

You can always disable Ebase browser check by using 'Ufs.skipBrowserAttributesCheck' property. We have done something similar in one of our projects where we have a .html page passing data into a Ebase form using "post" method.

With regards to the JSP invoking the URL, if the JSP is invoked programmatically (without browser), it will be the same issue as above as Ebase will run the 'browser check' first.

Ebase offers several options to invoke the scheduler. Have a look at http://dev-docs.verj.io/ufs/doc/scheduler.htm

According to me, disabling 'browser check' would be the easiest option. If you can't then you can always look at the JSP option

Hope this helps!

Hi Jon and Jignesh,

Thanks for your suggestions! As far as I know, 'Ufs.skipBrowserAttributesCheck' is a setting for the whole server, we need it for our other forms. Is this correct?

I will look into the JSP/scheduler options.

Jon, by 'Integration Service' do you mean a SOAP webservice? Unfortunatly, Ogone only supports a webpage to which it can post or get formvalues. Is it possible to call the 'integration service part' of a Ebase webservice as where it a form?

Yes. Ufs.skipBrowserAttributesCheck is for the whole server.

Another option I can think of:
If Ogone can send you a CSV/XML/etc file via FTP, then you can have a scheduled form that wakes up at fixed intervals and process the file(s).

An Integration Service is an Ebase published web service, you can't call these like a form. Sounds like this is not an option.

Regarding the Ufs.skipBrowserAttributesCheck flag, it applies to each web application as opposed to the whole server - subtle distinction. So you can set up a second web application e.g. ufs2, which has this option set and then use it just for these Ogone posts.

Sorry Jon/David! What I meant to say was "web application" rather then whole server.

Thank you Jon!

Thanks again!

I have made a JSP page which writes the (raw) Ogone data to a database. Using the scheduler, a form is run every minute to proccess the new data.

Validation and actions based on the payment result are thus handled by Ebase scripts.

I think that this is the most simple solution, and most important: it works
