Download Xholon

Download the Xholon Tool

Download the Xholon tool from sourceforge. Both the zip file and the tar.gz file include the Java source code and a jar file, complete with all the sample applications. Once you unzip or untar the downloaded file, you will immediately be able to run the examples. Just follow the instructions in README.txt included within the downloaded file. Starting with version 0.6, you can also separately download all the third-party libraries directly from the sourceforge site.

You will also need to download Java, either the Java Standard Edition SDK or JRE, if you don't already have either of these installed on your computer. Xholon has been tested with version 1.4.2 and version 1.5.0. Xholon will also compile with the Java Micro Edition (MIDP) libraries.

Download Third Party Libraries

Xholon can use a number of third party libraries for charts, graphs, and for several specialized purposes. The core part of Xholon, and most of the examples will work WITHOUT any of these packages. You can download this software from the following locations, OR you can download all the third-party libraries as a single file from the Xholon sourceforge site. In all cases the latest version should work as well as some of the earlier versions. You can install the .jar files anywhere on your system, but make sure you edit the Java CLASSPATH in xhn.bat (Windows) or xhn (Linux) in the Xholon home directory.
