The .jar files containing JoltBeans contain two versions of each JoltBean, a development version and a run-time version. The development version of each JoltBean name ends with the suffix Dev. The run-time version of each class name ends with the suffix Rt. For example, the development version of the class, JoltBean, is JoltBeanDev, while the run-time version of the same class is JoltBeanRt.

Use the development version of JoltBeans during the development process. The development JoltBeans have additional properties that enhance development in a graphic IDE. For example, the JoltBeans have graphic properties (“bean information”) that allow you to work with them as graphic icons in your development environment.

The run-time version of JoltBeans does not have these additional properties. You do not need the additional development properties of the beans at run time. The run-time beans are simply a pared down version of the development JoltBeans.

When you compile your application in your development environment, it is compiled using the development beans. However, if you want to run it from a command line outside of your development environment, it is recommended that you set the CLASSPATH so that the run-time beans are used when compiling your application.
