Etat HTTP 500 - "Servlet.init()" 为 Servlet AxisServlet 注入一个 généré une 异常

Question

我用 eclips 和 apache-tomcat-8.0.32 服务器和 axis2-1.7.0 在 java 中编写了一个简单的程序作为服务 web 这是我的代码：

package services;
import java.io.IOException;
import java.io.IOException;
import java.net.Socket;
import simObject.control.Traitement_motion_sensor;
import simObject.sensor.Motion_sensor;
import listener_Thread.Motion_sensor_listener;
import grid.Position;
import grid.Grid;
public class SW_motion_senssor 
{
    public Traitement_motion_sensor traitement_motion_sensor;
    public Socket s;
    private int id_motion_sensor ;
    public Motion_sensor_listener ecout_mos;    
    private int motion_exist;
    private int port_motion_sensor;
    public Motion_sensor m;
    private int orientation;
    boolean running =true;
    public Grid g;
    public Position p;
    public SW_motion_senssor() throws IOException  
    {
        m=new Motion_sensor(p,g,porte);
    }
    }
        public int Get_existe()
    {
        return m.getMotion_exist();
    }
    public Position Get_position()
    {
        return m.getPosition();

    }

}`

当我执行它时，出现以下错误：

Etat HTTP 500 - "Servlet.init()" pour la servlet AxisServlet a généré une exception

Answer 1

这些是您在日志中遇到的错误：

java.lang.NoClassDefFoundError: org/apache/ws/commons/schema/resolver/URIResolver java.lang.ClassNotFoundException: org.apache.ws.commons.schema.resolver.URIResolver

您的环境中缺少 XmlSchema jar。请拿下这个罐子再试一次。

Answer 2

在 Axis2 1.7.0 中，Apache XmlSchema 依赖项已从 1.4.x 更新到 2.x（这是一个重大更改）。可能 Eclipse 工具尚未更新以考虑到这一点，并且您仍然拥有 XmlSchema 1.4.x（或完全缺少依赖项）。

您需要将以下 JAR 添加到您的应用程序中：

http://search.maven.org/#search%7Cga%7C1%7Cg%3Aorg.apache.ws.xmlschema%20a%3Axmlschema-core

Answer 3

对于上述评论继续，将 xmlschema-core-2.2.1 放在 Tomcat 库或您正在使用的服务器库中......它对我有用......
