SpringLoaded is a web application project kickstart script/template.
It will create a skeleton web application project using some of the more popupalar frameworks available for Java.
It sets up the project structure with all the configuration files in place ready for a developer to customize.
SpringLoaded is not a round-trip engineering tool. It is simply a project template with a kickstart script.
Once you have kickstarted your project with SpringLoaded, it drops out of the picture allowing you the freedom to carry on your project's development the best you see fit.
