Liza,
I also had this problem initially. It had everything to do with my path settings, and my classpath settings. I'll give you an explanation of what I did on my windows2000 laptop to get things going.
Open cmd prompt and type path <enter>
verify that the path to the JDK is in there... C:\j2sdk1.4.1_02\bin
if not, you may set it by typeing set Path=.........
OR
right click my computer, properties, environmental variables.
ensure that something like the following is included in the PATH variable (if not edit it) C:\j2sdk1.4.1_02\bin . Keep in mind that entries are separated by semicolons.
Then open a cmd prompt, and move to a directory where your java file lives. Then compile it...
Now, if you can compile, but when you java TheFile... and you get an error... this may be due to the ClassPath setting. Open up a cmd prompt, make sure your in the root directory, and type in set ClassPath= <enter>
Yes, you just cleared out the classPath. This is what allowed me to execute the class files. Before that I was getting 'no such method, main' errors when there was absolutely a main method.
Hope this helps, it came from the Java2 Bible.
