大家好， 我想从Java代码中运行以下命令行命令 F:Dev \ Data \ ServerDir \ schema> admin -action runActivity -script 28.0.1234554321 -select"A111111，password3"-用户E0987808 -password apple -key XYZ12847NK. 为此，我编写了此代码

Hi All, I want to run following command line command from a java code F:Dev\Data\ServerDir\schema>admin -action runActivity -script 28.0.1234554321 -select "A111111,password3" -user E0987808 -password apple -key XYZ12847NK. For this i have written this code

import java.io.*; import java.lang.*; public class ProcessBuildDemo { /** * @param args */ public static void main(String[] args) { String b =("admin").concat(" ").concat("-").concat("action").concat(" ").concat("runActivity").concat(" ").concat("-").concat("script").concat(" ").concat("28.0.1234554321").concat(" ").concat("-").concat("selected").concat(" ").concat("\"").concat("A111111").concat(",").concat("password3").concat("\"").concat(" ").concat("-").concat("user").concat(" ").concat("E0987808").concat(" ").concat("-").concat("password").concat(" ").concat("apple").concat(" ").concat("-").concat("key").concat(" ").concat("XYZ12847NK"); //String a = "WindowsApplication1.exe"; //String [] command= {"CMD","/c",a}; String [] command = {"CMD","/c",b}; ProcessBuilder pb= new ProcessBuilder(command); pb.directory(new File("F:\\Dev\\ServerDir\\schema")); try { pb.start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

每当我运行此代码时，我都会在线程"main" java.lang.NoClassDefFoundError:ProcessBuildDemo/class 中遇到提及异常的异常. 我是Java新手，请帮助我解决此问题.

Whenever I am running this code i am getting an Exception mentioning Exception in thread "main" java.lang.NoClassDefFoundError: ProcessBuildDemo/class I am new in java please help me resolving this issue.
