Spring 3.0, a major upgrade to the popular open-source Java development framework, is being introduced Monday by SpringSource, featuring full REST support for rich Web applications as well as an expression language.

SpringSource, which recently was acquired by VMware, also is announcing SpringSource tc Server Developer Edition, offering a runtime environment for building Spring applications. And tc Server is compatible with the Apache Tomcat Java application server.

The Spring Framework is used by more than 3 million developers, SpringSource said.

"Spring 3.0 makes it even easier for developers to build flexible, high-quality applications while providing a foundation for innovation in other open-source projects and commercial projects," said Rod Johnson, general manager of the SpringSource division of VMware.
