Contiued with the above query.

I have done one change. And then it is working fine . No need to use c:\MavenDemos\MyPro>java -cp target/classes com.acc.App

I have removed CLASSPATH variable from user variable in Env. variables.

Then it is working fine. so now i just type c:\MavenDemos\MyPro\target\classes>java com.acc.App
