Don't worry, I won't get aggravated. I'm not so sure I cover installing the JDK in my tutorial, I probably should. They've got instructions though. If you've already installed it, then most likely you have to set the PATH environment variable in order to do it easily. What OS are you running? I only know how to do it in Win2K, which is probably not what you're using... But anyway, you need to append the directory which stores all the executables (java, javac, javaw, jar) to that environment variable. So look for the directory you installed everything into, which is probably C:\j2sdk1.4.1_01. Then edit your path variable so it has C:\j2sdk1.4.1_01\bin at the very beginning. I have no clue how to do this in 98/ME/XP, so if someone else wouldn't mind telling him how, I'd appreciate it. I gotta run to school :\
