jetty：如何声明JVM范围的jndi条目并绑定到java:comp/env

我试图在Jetty服务器中定义一些JNDI条目（它们将是JVM范围的），但它们没有像预期的那样自动绑定到“java:comp/env”命名空间。我正在以下网址查看文档：

这是我的jetty.xml：

<Configure id="server" class="org.eclipse.jetty.server.Server">

<New class="org.eclipse.jetty.plus.jndi.EnvEntry">
    <Arg></Arg>
    <Arg>prop/someValue</Arg>
    <Arg type="java.lang.String">hello</Arg>
    <Arg type="boolean">true</Arg>
</New>

</Configure>

道具/价值
你好
真的

正如Jetty示例所示，我希望它绑定到“java:comp/env/prop/someValue”，但是“java:comp/env”似乎根本没有被创建

但是，查找“prop/someValue”确实有效

注意-我没有webapp，所以没有WEB-INF/jetty-env.xml或WEB.xml。我只是启动一个Jetty服务器，并尝试使用所需的JNDI条目对其进行配置

还尝试使用“bindToENC”方法将我的条目显式绑定到：

但这会导致服务器启动失败：

有人知道如何让它工作吗？

您可以通过两种方式将

prop/someValue

绑定到

java:comp/env/prop/someValue

。第一个是引用web.xml中的env条目，如下所示：

道具/价值
java.lang.String
你好

但是，与您的情况一样，您没有WEB-INF/WEB.xml，根据J2EE，有效的WEB应用程序不需要WEB-INF/WEB.xml。您可以使用

bindToENC

方法将绑定保留到Jetty。可以这样做：
