Project: Convert current Tomcat valves to Servlet Filters.
Abstract: Apache Tomcat is an implementation of the Java Servlet and JavaServer Pages technologies. It is famous and widely used. It is also a component of an Application Server named JBoss Application Server. My task in this project is to convert current Tomcat valve based implementation into Servlet Filters which is consistent with the Servlet Specification.
Here is the roughly plan for this project:
Week 1: finish the very first valve - AccessLogValve, including testing and documentation work. The deliverables after this week are the source code of AccessLogFilter, including unit test code and documentation of this class.
Week 2: finish working with the ErrorReportValve and SSLValve
Week 3: finish working with StandardEngineValve, move its functionality into some "engine" level filter. And I also need to twist the "Engine", "Host", "Context" and "Wrapper" class a little to move on in this week.
Week 4: finish working with StandardHostValve, move its functionality into some "host" level filter.
Week 5: finish working with StandardContextValve, move its functionality into some "context" level filter.
Week 6: finish working with StandardWrapperValve, move its functionality into some "indivisual servlet" level filter.
Week 7 - 8: Do some integration test with current work to guarantee I do not break anything.
Week 9: finish working with RequestFilterValve and its 2 subclasses, refactor their functionality out into 3 corresponding filter classes.
Week 10 - 11: Refactor the functionality out of the AuthenticatorBase class and its subclasses into some structure which is consistent with the Servlet Container Profile in JSR-196.
Week 12: Integration test all the work. Check the missing documents and complete them.
