Re: Please Help
Ben, I managed to solved the problem. There is a typing error in the path section. Anyway, tq Ben.I really appreciate your help. - Original Message - From: Ben Kimball [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, July 18, 2001 5:41 AM Subject: Re: Please Help Not totally sure - I do all my Java development on Linux, much less hassle, but you might try the following: Since it is complaining about setting it dynamically, maybe you can set it in the environmental properties (which will probably require a reboot) - right click on My Computer, select Properties, then select Environment (or something like that, I'm doing this from memory, as I'm running under Linux right now) and one of the things that shows under that should be the PATH variable - you should be able to set that with the long (Non-DOS 8.3) pathnames. Try plugging the info in there, rebooting, then seeing if the info stays in the CLASSPATH.
