This project is used in the following archived projects that were used to exchange messages in Peppol:

  • as2-peppol-client - a stand alone AS2 client that is capable of sending Peppol compliant e-Procurement documents.
  • as2-peppol-servlet - integration into the Servlet specifications and for use with the Peppol transport infrastructure including SBDH (Standard Business Document Header) handling.
  • as2-peppol-server - a stand alone Servlet based server to receive Peppol AS2 messages.

Peppol switched protocol to AS4 that's why it was discontinued.
