为什么我无法通过 axis2 localhost 查看此数据库中的服务？

Question

我一直在学习网络服务和其他东西，终于能够构建我的第一个 gimmick 代码，但是每当我尝试在 eclipse 上创建我的 DAO class 的网络服务时，我最终都没有能够在本地主机上访问它的会话（服务、验证、管理）。

其他信息：我将 axis2 与 tomcat 6.0.41 一起使用（出于教程目的）并尝试通过 [=12= 访问最近创建的 MySQL 数据库 "ExemploWS" ], 在我尝试浏览它之前它工作正常。

同时使用 XAMPP 控制面板和 Apache 并 MySQL 启动。所以我要离开连接 class 然后在访问 http://localhost:8080/ExemploWS/services/listServices.

时出现错误

package br.com.ExemploWS;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class ConectaMySQL { 
private static final String url = "jdcb:mysql://localhost/exemplows";
private static final String user = "root";
private static final String pass = "";

public static Connection obtemConexao() throws SQLException {
    try {
        Class.forName("com.mysql.jdbc.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    return DriverManager.getConnection(url,user,pass);
}
}

将此 class 添加到您的应用程序中，它丢失了：

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

它在 commons-xmlschema 中，在这里找到它：http://mvnrepository.com/artifact/org.apache.ws.commons.schema/XmlSchema
