Can someone tell me what the name of the Java runtime executable command is, and where it is located? If I want to run XXX.jar I can doubleclick on it in the file manager and it runs fine, but if I type "java XXX.jar" or "jre XXX.jar" at the command line it throws up an error. I went to the web pages for openjdk but couldn't find the answer.

Also, is there any hope of a java package that runs faster? The java software I want to run is Calgoo Calendar, which is a dog but is the only Linux calendar I know of that you can use offline and does 2-way synchronization with both Google Calendar and 30Boxes. It crashes under Jalimo, and while it loads under Debian it takes around 10 minutes to start up, sometimes doesn't start at all, and is slow as molasses.

Thanks, David
