I have Teach Yourself Java 2 from SAMS, and it came with 1.2 SDK. The installation advice is to put a CLASSPATH= (the path to tools.jar)in autoexec.bat, but my Win98 keeps saying that it is invalid line and ignores it during bootup;indeed there is not CLASSPATH command anywhere in Windows documentation. I keep having erratic class not def or not found errors. I can't be the only one with this problem! What do I do?
