design patterns used in tomcat design

[gayathri sridhar]

to the author / to those who have already finished reading the book,
What design patterns have been used extensively in the tomcat code base?
Are there some nice stuff that has been used. Would be great if somebody could share their learnings and also the tomcat module that has been implemented using the dp.

Does the book talk about these design patterns while describing Tomcat 4.x/5.x architecture?

I think yes. I was reading through the chapters and there was one place were the facade pattern was nicely described. How HttpRequest object is wrapped using facade when passing it on to other modules so that the other modules cannot invoke the private methods of the actual HttpRequest implementation.
