linux - 错误 : Could not find or load main class

Question

我执行了这个命令来编译我的程序

java -Xms16m -Xmx64m -cp ".:boilerpipe-1.2.0.jar:lib/nekohtml-1.9.13.jar:lib/xerces-2.9.1.jar:lib/langdetect.jar:lib/jsonic-1.2.8.jar" ExampleProgram.java

它报告这个错误:

Error: Could not find or load main class ExampleProgram.java

这是 ExampleProgram.java:

import java.io.InputStream;
import java.io.FileReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.io.IOException;

import org.xml.sax.InputSource;

import com.sun.net.httpserver.HttpServer;

public class ExampleProgram {

    public static void main(String[] args) throws Exception {
        EveryDetector evr = new EveryDetector();
        InetSocketAddress addr = new InetSocketAddress("127.0.0.1",8080);
        HttpServer server = HttpServer.create(addr, 0);

        MyHandler hndl = new MyHandler();
        hndl.setDetector(evr);

        MyHandlerExtractContent hnd2 = new MyHandlerExtractContent();
        hnd2.setDetector(evr);

        MyHandlerDetectLanguage hnd3 = new MyHandlerDetectLanguage();
        hnd3.setDetector(evr);

        server.createContext("/",hndl);
        server.createContext("/extractcontent",hnd2);
        server.createContext("/detectlanguage",hnd3);
        server.setExecutor(Executors.newCachedThreadPool());
        server.start();
        System.out.println("Server is listening on port 8080" );
    }
}

我该如何解决我的问题？

对我来说，在 Windows 环境中这有效(我的类(class)位置:C:/MyFolder/MyClass.java):

cd C:/MyFolder/MyClass.java

编译:

C:/MyFolder/MyClass.java> javac MyClass.java

执行:

C:/MyFolder/MyClass.java> java -classpath C:/external.jar;. MyClass
