You get a lot of functionality in the JDK. I'd try there first. My 
thought on using lots of different projects is that I don't mind looking 
at OS code and more often than not, if it is a well known project, it 
will be stable and they will take patches. Therefore, I tend to use lots 
of other projects in a well structured manner and try to write very 
little. You just have to make sure you pick good code to use and stay 
away from dead projects. AND most importantly, don't be afraid to dive 
into OS code and fix bugs. You'll save time in the long run in most 
cases this way (I've found).
