EMMA [MAIN_METHOD_NOT_FOUND]

Question

Am trying to use Emma for checking the code coverage of my application and am trying to run like this

D:\bin>java  -cp val.jar;emma.jar emmarun -r html -cp . com.val.ui.ValidatorClient



EMMA: no coverage data collected at runtime [all reports will be empty]
EMMA: writing [html] report to [D:\bin\coverage\index.html] ...
[EMMA v2.0, build 5312]
emmarun: [MAIN_METHOD_NOT_FOUND] application class [com.psft.sqlval.ui.Validator
Client] does not have a runnable public main() method
Exception in thread "main" com.vladium.emma.EMMARuntimeException: [MAIN_METHOD_N

        at com.vladium.emma.rt.AppRunner._run(AppRunner.java:493)
        ... 3 more

But my class ValidatorClient.java has a valid main method

public class ValidatorClient
{
 ...

 public static void main (String[] args) throws Exception
  {
     ....

Can somebody throw some light on this?

Thanks in advance
