I developed an applet using JDK 1.1 (Borland compiler) and tested it extensively on Win95/98 and NT.....whith success. Then I tried the same thing on a Mac (OS 7.6, 8, 8.5) and got an error message 'Applet can't start : error : java.lang.NoSuchMethodError : ......etc.'. I changed functions, stripped the program to just a couple of methods. As soon as I use 'setLocation()', 'setBounds()', TextArea, Button .... I receive the message NoSuchMethodError. I can draw lines and write text though (in paint() ). I use Netscape 4.5 on both platforms. I used different codebases (applet sent by ftp or http) (same difference) and several Mac/PC (same difference). So what the heck is it ? Thanks for getting me out of this nightmare L.
