Apache SOAP 2.2 Overview Page 4
Apache SOAP -- Presentation
Apache SOAP is an Apache project that defines the SOAP protocol in Java. This project is based on the source of IBM's SOAP application, SOAP 4J. The latest version of this implementation, dated May 30, 2001, is version 2.2 of the project.
Apache SOAP 2.2 defines almost all of the SOAP1.1 note, in the same way as the whole "SOAP Messages with Attachments" Note from the W3C.
The project essentially consists of four parts:
- The definition of an API for developing SOAP services
- A server-side infrastructure for deploying and running SOAP services
- Support for three forms of encoding: SOAP 1.1, XML, and XMI
- Use of HTTP and SMTP protocols
The characteristics of Apache SOAP are very important for interoperability between systems.
