Payware API payment example from java language

Payware API is one of the easy way to make payment online using no API setup.
It has made a simple java example to post the valid XML as an request to the Payware API and in return we get the response back.

We must have the demo account setup with the payware before we try this example else it give the error with invalid login details.

It's very good API that support the multiple plateform(visual basic,java .net) to make the payment online.
