SpringSource Tool Suite™ (STS) provides the best Eclipse-powered development environment for building Spring-powered enterprise applications. STS supplies tools for all of the latest enterprise Java, Spring, Groovy and Grails based technologies as well as the most advanced tooling available for enterprise OSGi development.
Included with STS is the developer edition of vFabric tc Server, the drop-in replacement for Apache Tomcat that’s optimized for Spring. With its Spring Insight console, tc Server Developer Edition provides a graphical real-time view of application performance metrics that lets developers identify and diagnose problems from their desktops.
STS supports application targeting to local, virtual and cloud-based servers. It is freely available for development and internal business operations use with no time limits.
This is a must for Spring, Groovy or Grails developers.
