QXServlet - A Servlet Extension for Qt

Status Chart

This chart shows the status of the individual classes that make up the servlet API.

Introduction

The QXServlet extension provides an easy to use way to write extensions for web servers based on Java Servlets. The servlet API provides an abstraction that makes it easy to write extensions, and it is designed to be server and platform independent. The QXServlet API is a C++/Qt mapping of the Java API, so the existing Java documentation is directly applicable.

Currently QXServlet implements large parts of the 1.0, 2.0 and 2.1 servlet APIs, but supports none of them completely. This should change rapidly as there is only a small amount of work remaining.

Ultimately I hope to write a module for Apache that will allow it to use Qt servlets directly, but at the moment the only implementation of the API is the standalone web server included with the extension.

Status

The QXServlet API is currently a work in progress, and while enough of the implementation is in place for simple servlets to operate, there is still a lot of work to do.

Currently TODO

• Finish HTTP status code enum.
• Connect session class to an implementation.
• Add cookie support to requests and responses.
• Session life cycle is totally unimplemented. (findSession() etc), though the session class itself and the binding events are implemented.
• Split the interfaces from the implementation.
• Check the life cycle of each object is correct.
