尝试使用hello-word Web服务时出错:ClassNotFoundException:org.apache.ax

Question

从现在起2-3天内我就出现了一个错误，所以我有一个axis2项目，我正在尝试在服务器端使用以下Web服务：

HelloService.java

public class HelloService {
public String sayHelloWorldFrom(String from) {
String result = "Hello, world, from " + from;
System.out.println(result);
return result;
}
}

这是我生成的wsdl：

但是，当我尝试从客户端使用helloworld服务时，我会出现以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/axis2/databinding/ADBException
at org.hello.HelloService.main(HelloService.java:10)
Caused by: java.lang.ClassNotFoundException: org.apache.axis2.databinding.ADBException

Process finished with exit code 1

因此，正如您在HelloService.java中看到的，我不使用jaw-xs注释，因为Tomcat服务器不识别注释

谢谢你的帮助。

• 服务器
• 客户

一些依赖项是用Provided作用域定义的，它在运行时不会自动添加。

解决方案是更改pom.xml中依赖项的范围，或者更改运行/调试配置以在运行时包含具有所提供范围的依赖项。
