NOTICE: when you run a java class, do not use "java Hello.class", instead, use "java Hello". Because "." is expained as package separater. How is a java class called? first the jvm search the classpath, then the codebase, just like when running a program in dos it search the path. then, it add the package to the classpath or codebase and invoke the class. for example: current classpath set to d:\java, and the command-line like "java examples.test.TestJava", the package sentence in your TestJava.java should be: package examples.test; and there should be a dir structure like this: d:\java\examples\testand your TestJava.java and TestJava.class should be in this dir.
