I'm currently working on a project which will use a j2me application on phone which will make a payment from a paypal users account, then send the token to another server which will verify the transaction, then carried out a task on the server.

Currently i'm looking into using the web services API as it should be possible to use SOAP based system in order to process the transaction via the Direct payment api.

If a phone is devloped with the incorporation of JSR 172, will it be possible to parse XML security on the device.

If anyone has any experience using paypal on a j2me application, any advice would be appreciated.
