mybatis xml配置文件無法解析

Question

我在讀取MyBatis 3.0.2的xml配置文件時遇到問題。

我必須在Axis2 1.5的Web服務中使用它。我有這樣的代碼類：

public static org.apache.ibatis.session.SqlSessionFactory getSqlMapper() { 
    org.apache.ibatis.session.SqlSessionFactory sqlMapper; 
    try { 
     String resource = "MyBatis.xml"; 
     java.io.Reader reader = org.apache.ibatis.io.Resources.getResourceAsReader(resource); 
     sqlMapper = new org.apache.ibatis.session.SqlSessionFactoryBuilder().build(reader); 
    } catch (Exception e) { 
     // Si hay un error en este punto, no importa cual sea. Será un error irrecuperable del cual 
     // nos interesará solo estar informados. 
     // Deberás registrar el error y reenviar la excepción de forma que se te notifique el 
     // problema de forma inmediata. 
     e.printStackTrace(); 
     throw new RuntimeException ("Error initializing MyAppSqlConfig class. Cause: " + e); 
    } 
    return sqlMapper; 
} 

其中MyBatis.xml是配置文件。當我打電話給getSqlMapper，在該行sqlMapper = new org...我得到這個異常：

我有這樣的錯誤，在互聯網上閱讀了很多，但它帶給我到任何地方。它應該在兩個不同的地方定義類javax.xml.namespace.Qname似乎是一個問題，但我不知道如何解決它。

任何人都知道解決方案嗎？

這個link可能是有用的。值得注意的部分是加載類的序列也是一個因素，而不僅僅是兩個JAR中相同類的存在。
