轻松启动独立JNDI服务器（并注册一些资源） [英] Easy way to start a standalone JNDI server (and register some resources)

问题描述

出于测试目的，我正在寻找一种简单的方法来启动独立的 JNDI服务器，并将我的javax.sql.DataSource绑定到java：/ comp / env / jdbc / mydatasource以编程方式。

For testing purposes, I'm looking for a simple way to start a standalone JNDI server, and bind my javax.sql.DataSource to "java:/comp/env/jdbc/mydatasource" programmatically.

服务器应将自身绑定到某个URL，例如：java.naming.provider.url = jnp：// localhost：1099（不一定是JNP），这样我就可以从另一个进程查找我的数据源。我不关心我必须使用哪个JNDI服务器实现（但我不想启动一个成熟的JavaEE服务器）。

The server should bind itself to some URL, for example: "java.naming.provider.url=jnp://localhost:1099" (doesn't have to be JNP), so that I can look up my datasource from another process. I don't care about which JNDI server implementation I'll have to use (but I don't want to start a full-blown JavaEE server).

这应该很容易，但令我惊讶的是，我找不到任何（工作）教程。

This should be so easy, but to my surprise, I couldn't find any (working) tutorial.

推荐答案

JDK包含一个< a href =http://download.oracle.com/javase/6/docs/technotes/guides/jndi/jndi-rmi.html\"rel =nofollow> RMI注册管理机构的JNDI提供商。这意味着您可以将RMI注册表用作JNDI服务器。所以，只需启动 rmiregistry ，设置 java.naming.factory.initial 到 com.sun.jndi.rmi.registry.RegistryContextFactory ，你就走了。

The JDK contains a JNDI provider for the RMI registry. That means you can use the RMI registry as a JNDI server. So, just start rmiregistry, set java.naming.factory.initial to com.sun.jndi.rmi.registry.RegistryContextFactory, and you're away.

RMI注册表有一个扁平的命名空间，所以你将无法绑定到java：/ comp / env / jdbc / mydatasource，但你将能够绑定到的东西，所以它将接受java：/ comp / env / jdbc / mydatasource，但是将它视为单个组件名称（谢谢，@ EJP）。

The RMI registry has a flat namespace, so you won't be able to bind to java:/comp/env/jdbc/mydatasource, but you will be able to bind to something so it will accept java:/comp/env/jdbc/mydatasource, but will treat it as a single-component name (thanks, @EJP).

我写了一个小应用程序来演示如何执行此操作： https://bitbucket.org/twic/jndiserver/src

I've written a small application to demonstrate how to do this: https://bitbucket.org/twic/jndiserver/src

我仍然不知道JNP服务器应该如何工作。

I still have no idea how the JNP server is supposed to work.
