The Spring IDE team has released the latest version of Spring IDE, which includes great visualizing support to increase productivity. Here is the text from official spring site.
The new features includes the highly-anticipated Spring Web Flow graphical visualizer and editor. The new support allows developers to edit XML-based flow definitions graphically, and enables greater productivity and communication with end users.
In addition to the graphical piece, Spring IDE 2.0 M3 also delivers a Web Flow XML editor that provides content assist and semantic validation to improve the quality of your flow definitions. : Source: www.springframework.org
