Re: Dev2K for web java errors :(

I didn't see where you said which browser you are using. Based on the error (which I ran into) you are using Netscape Communicator 4.02 or 4.03. There is a JDK patch that you must install in Navigator for these forms to work. This patch adds a bunch of database classes to Netscape's JDK support. I can't remember exactly where this patch is, but go to http://home.netscape.com and follow the developer link. The JDK patch should be mentioned there.

Keep in mind that this patch is a preview release. I still have problems with it. For instance the browser locks up for no apparent reason. Even when I'm just typing in a text field. Weird!

Good Luck!
