add moneybookers as payment option to java gae paypal interface

Hello I have with me a working Google App Engine JAva interface, that accepts payments (either one time or recurring) through Paypal. I want you to add moneybookers as a payment gateway to this script. The existing script has option of enabling either one time, or recurring payments. I want you to keep this logic, simply add moneybookers as an option for both recurring and one time payments. Simple work for a good java coder. I should be able to specify live or sandbox mode through Admin->Settings, in addition to the regular Moneybookers parameters. Also, I should be able to enable both moneybookers and paypal as options for payment. Regards, Arvind.
