If you want to study how to write good code, the best example would be the actual java source, you can look at the source code for the collection api and other similar apis within java. The source code is available in the jdk folder as "src.zip".
Do share your source code for your web application so that we can guide you along.
I don't know how your general knoweledge of java is, but if you're familiar enough with the basics, this might be a good place to start.
Also to state the obvious, know that most idea's let you on start of a new project choose whitch kind of program you want to create, if you choose a webapp, you start off with a mini fullworking webapp, provided you did the prerequisites, like installing a webcontainer.
It's good to be able to use someting, it's better to understand how it works.
