Question

我编写了以下代码，它是http://www.nanonull.com/TimeService/TimeService.asmx?WSDL的客户端wsdl：

package time;
class Client {
 public static void main(String args[]){
        TimeService service = new TimeService();
        TimeServiceSoap port= service.getTimeServiceSoap();
        String result = port.getTimeZoneTime("UTC+10");
        System.out.println("Time is "+result);
 }
}

但是当我尝试用java运行它时，我得到以下结果：

C:\Program Files\Java\jdk1.6.0_22\bin>java client.Client
Exception in thread "main" java.lang.NoClassDefFoundError: client/Client
Caused by: java.lang.ClassNotFoundException: client.Client
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: client.Client.  Program will exit.

这个错误是否意味着我应该导入任何类？

Answer 1

您编写的主要课程是time.Client，但您尝试运行client.Client。更好地运行它：

java time.Client

如果这没有帮助，那么你有一个类路径问题 - java无法在类路径中找到主类。使用-classpath option设置类路径：

java -classpath classes-directory;list-of-jar-files time.Client

Answer 2

您需要设置类路径：

C:\Program Files\Java\jdk1.6.0_22\bin>java -cp . client.Client

运行java wsdl客户端时找不到主类错误
