Can you post more detail about what you are doing? Such as the command line or IDE action that you are attempting, and the FULL error message that you get. Screenshots can often be useful if you don't know exactly what to provide. The code too, if it's not too big, or at least the main class, would be useful to us.

Also, if you are running this from the command line, can you provide the directory that you are in and the directory listing of that directory? Also, what operating system?

Set PATH and CLASSPATH correctly before compiling the java file.
Amitkumar PSr. ConsultantCommented:
Looking at error, it seems that you are trying to run a program which is either not compiled or doesnt have main method.

Please share more details as suggested by mccarl.

Also, set the path/classpath as mentioned by krishna, if you are not able to compile your java file.
