HI For run the CF Java Editor you need the 1.3.1 runtime or the 1.3.1. java standard edition. http://java.sun.com/j2se/1.3/ runtime & standard edition link When you had download the runtime, read the docs. After installing the runtime and downloading the CFJavaEditor.zip, you can start the Editor with the CFJavaEditor.jar. the command line java -jar CFJavaEditor.jar will start it. i *hope* it will run, because sometimes jar files from other systems (windows -> java) will not run. In this case you has to recompile it. You CAN also start it with the *.class files in the source directory or recompile it. Look in the run.bat how its starting. I had not included a make file, i used the MS Visual Studio Java editor, so you must do ti for yourself. Michael
