sun IDEs are not user friendly. they are just good samples of java/j2ee programming ! the best IDE for servlet  works is jbuilder. it is powerfull and simple. it also has a built-in tomcat  configured in it. u also can use jdeveloper from oracle or websphere.
Intellij idea is also a good ide but u have to add a server  to it.
i myself use jdeveloper. u may download it from oracle for free.
