Question

I have the following directory structure:

C:\CheckinProject\sources\main\EmailProcessor.java<br/>
                         \compile-and-run.bat<br/>
                 \classes\main\EmailProcessor.class

The file EmailProcessor.java contains this:

package main;

public class EmailProcessor {
    public static void main(String args[]) {
        System.out.println();
    }
}

The file compile-and-run.bat contains this:

javac -d ..\classes main\EmailProcessor.java 
java -cp ..\classes ..\classes\main\EmailProcessor

When I run compile-and-run.bat I get this error:

Error: Could not find or load main class ..\classes\main\EmailProcessor

Why can’t it find or load my main class???

Answer 1

You’re specifying ..\classes\EmailProcessor as if Java wants the stem of a filename. It doesn’t – it wants a fully-qualified class name. So this should work:

java -cp ..\classes main.EmailProcessor
