And pretty weak ones at that. Here's a list of servlet development tools you can use so you won't be a servlet weakling. BrowserHawk4J is a JavaBean that knows most everything about client browsers and their capabilities, and makes that information available to servlets and JSPs. Sites that use BrowserHawk4J can build pages perfectly targetted for each visitor, making for the best experience for the user, while providing graceful degradation for users with older browsers. XDE Java Spell Checker can use a servlet back-end to spell check an HTML page's textarea on the front end.
Prices vary depending on usage.
Ant is an amazingly cool build tool. It's named ant because it's a small tool with power enough to build large projects. Ant now is the build tool of choice for most of the Java-Apache projects. Ant has recently become its own project with a separate workspace so you can use Ant whether or not you're interested in Tomcat. A manual is available in the distribution under the docs directory.
