Is the class that you are trying to load is part of any package or the default package?

I assume your class is in d:\JavaProg. Does it try to load any other class?

Please attach your sample program, that will help investigate this.

Set you'r class path where the JDK 's installed.  Right click on my computer go to Advanced tab. Then Select Environment Variable. On System variable section Edit the path.

insert a semicolon then write the absolute path where the JDK 's Installed in my case it case :

D:\oracle\product\10.2.0\client_1\bin;D:\oracle\product\10.2.0\db_1\bin;D:\Program Files\ImageMagick-6.6.6-Q16;D:\Program Files\CollabNet Subversion Client;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;D:\Program Files\Intel\DMIX;D:\Program Files\TortoiseSVN\bin;D:\Program Files\Java\jdk1.6.0_10\bin

Refer to:http://download.oracle.com/javase/1.5.0/docs/tooldocs/windows/classpath.html
