I had this issue on linux. Turned out it was simply that the path had a space in it. When this was changed it worked fine.

graysonc — Wed, 19 Aug 2009 06:45:37 -0000

Okay, here's the mistake I made (which almost drove me crazy):
set classpath = .;M:\;C:\Program Files\Java\jre1.6.0_14\bin;
is NOT the same as:
set classpath=.;M:\;C:\Program Files\Java\jre1.6.0_14\bin;
If you put spaces around the '=' it won't work. The file would always compile but would only run without the package designation. As soon as I added the 'package' statement at the top I could compile it but it would always give the above error when I tried to run it. Hope this helps someone.

For a beginner you may get this error also if you run:
java helloworld.class
Instead try to run:
java helloworld

i don't understand this 'Executing your program using this command should correct the problem:
java -classpath . helloworld' ?
where / how do i execute with another classpath?

It might be due to packages.
Try removing any "package" from the top of your *.java files.

nahawand — Mon, 27 Jul 2009 16:20:39 -0000

That worked! Thanks a lot,

It would probably help if you explicity indicate that the extension ".class" should not be used when using "-classpath" .
