The following links lead you to prerequisites you will need in order to run JCycleData. Please note that these are one-time downloads.
- Java Web start can be downloaded from http://java.sun.com/products/javawebstart/
- Java2 Run Time Environment (JRE)
- You can get the XML-Libraries from Apache.org if you want the most up-to-date versions. I have used Xalan 2.2.0.
