Java JNDI查找失败（NameNotFoundException）

更新：似乎只有当我尝试在本地调试时，这才是一个问题。在Jetty（不是同一台机器）上发布时，效果非常好。在本地调试时，是否可以配置Run jetty Run使用的jetty.xml文件

我只是浪费了一个下午试图找出原因，但没有成功

我正在为我的应用程序设置一个c3p0连接池。顺便说一下，我用的是7号码头。问题是，当我执行context.lookup获取数据源时，会出现以下异常：

我有一个jndi.properties文件来配置我的InitialContext（位于我的资源文件夹src/main/resources中）

我在webapp/WEB-INF文件夹中还有一个jetty env.xml文件：

<Configure class="org.mortbay.jetty.webapp.WebAppContext">

<!--<Set name="ConfigurationClasses">
   <Ref id="plusConfig"/>
</Set>  -->

<!-- MySql datasource org.eclipse.jetty.plus.jndi.Resource Factory-->
<New id="DSTest" class="org.mortbay.jetty.plus.naming.Resource">
    <Arg></Arg>
    <Arg>jdbc/DSTest</Arg>
    <Arg>
     <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <Set name="driverClassName">com.mysql.jdbc.Driver</Set>
        <Set name="url">jdbc:mysql://host/</Set>
        <Set name="username">username</Set>
        <Set name="password">password</Set>
        <Set name="checkoutTimeout">5000</Set>
        <Set name="initialPoolSize">10</Set>
        <Set name="maxIdleTime">30</Set>
        <Set name="maxPoolSize">160</Set>

        <Set name="maxConnectionAge">0</Set>

    </New>
  </Arg>
 </New>
</Configure>

愚蠢的问题，但本页指出，将JNDI与Jetty一起使用是需要启用的可选功能

---

具体来说，它说执行此操作的类是org.mortbay.jetty.plus.webapp.Configuration，当我们为它定义org.mortbay.jetty.webapp.WebAppContext时，我们会在要应用于webapp的配置列表中指定它的名称。

也许我很傻，但尝试将“jdbc/DSTest”作为JNDI名称，而不是“env/jdbc/DSTest”。只是尝试了一下，但是运气不好：/你用的是7号码头还是6号码头？看起来在Jetty 7中org.mortbay已经改为org.eclipse，但是您的资源定义类仍然是org.mortbay。这可能是问题吗？是的，我的码头已经配置好了。不过谢谢：）
