发帖数: 137 | 3 Thank you.
And I tried to add C:\j2sdk1.4.1_01\bin to the classpath variable. It solves
the problem.

发帖数: 3972 | 5 Actually, you did not solve the problem well.
Next time, you run a java program in another directory, you will have
the same issue.
What you need to do is add your currently directory . to the classpath.
cang did it in commandline, you can make change permanently in Enviroment
variable.

发帖数: 137 | 8 I just tested it again in Windows XP. It seems that
1. If I don't put anything in environment variable classpath, I can run
java classname
as long as file classname.class is in the current directory.
2. If I put some path(es) in classpath already, I should also put '.'
there so that I can run
java classname
in current directory.
Please correct me if I am wrong or not complete. Thanks.

发帖数: 3972 | 9 You are difinitely right. By default your j2sdk installation will
put current directory in classpath. But if you introduce your own CLASSPATH,
you overwrite the default one. You have to put , in classpath explicitly.
there?
classpath.
