Question

当我使用PropertiesConfiguration加载某些属性时，我有一个奇怪的异常。我在Web服务上工作，之前我成功使用 java.util.Properties; 调用文件 .properties 。对于这个项目，我需要在修改文件 .properties 时刷新Tomcat，所以我想使用 commons.configuration.Configuration; ，但是我收到一些例外。这是我调用config.properties文件的代码：

private String getProperty(String property)
{
    String value = null;
    PropertiesConfiguration config = new PropertiesConfiguration();
    try {
        config.load(getClass().getResourceAsStream("config.properties"));
        config.setReloadingStrategy(new FileChangedReloadingStrategy());
        value = config.getString(property);
    } catch (ConfigurationException e) {
        e.printStackTrace();
    }       
    return value;
}

例外情况如下：

我引用了这个post，所以我知道我必须包含一些包（所以我做了），这里包含了不同的包：

Apache Tomcat v7.0
公地beanutilss-1.8.3.jar
公地编解码器-1.7.jar
公共收集-3.2.1.jar
公地配置-1.9.jar
公地文件上传-1.2.2.jar
公地的JXPath-1.3.jar
公地琅2.6.jar
共享记录-1.1.1.jar
EAR Librairies
JRE系统库
网络应用程序库

我还可以添加webservice的结果，而不是真的知道它是否有用，以防万一：

Exception: java.lang.NoClassDefFoundError: org/apache/commons/configuration/ConfigurationException; nested exception is: java.lang.NoClassDefFoundError: org/apache/commons/configuration/ConfigurationException Message: java.lang.NoClassDefFoundError: org/apache/commons/configuration/ConfigurationException; nested exception is: java.lang.NoClassDefFoundError: org/apache/commons/configuration/ConfigurationException

我有点厌倦了在网上寻求并没有成功解决问题。感谢您的回答，如果有人有解决这个问题的线索，那将是受欢迎的：）
