Has anyone figured out a way to have java programs (not javascript) control an RCX via the internet? I was thinking of java on jsp or jhtml pages. Any thoughts or ideas? (25 years ago, 7-Jun-01, to lugnet.robotics.rcx.java)

At least it runs. :-) That error means that for some reason install could not create the directory .lvi in your windows directory.
