Eclipse is a free and open source IDE (Integrated Development Environment) for developing a variety of applications from console and GUI applications on the client-side to web applications on the server. It has specific editions for different programming languages. In case of JSP, it offers Eclipse IDE for Java EE Developers for developing JSP based web applications.
The purpose of an IDE is to make the task of developing applications much easier. In the context of JSP web applications, Eclipse supports syntax coloring and highlighting, intellisense and code completion. It supports TDD (Test Driven Deployment). It has built-in support for debugging and allows one-click compilation and deployment of JSP applications.
