如何从Web容器外部查找JNDI数据源？ [英] How do I lookup a JNDI Datasource from outside a web container?
问题描述
我设置了以下环境：
- Java 1.5
- Sun Application Server 8.2
- Oracle 10 XE
- Struts 2
- Hibernate
- Java 1.5
- Sun Application Server 8.2
- Oracle 10 XE
- Struts 2
- Hibernate
我很想知道如何编写可以引用应用服务器提供的JNDI数据源的Java客户端（即Web应用程序之外）的代码。
I'm interested to know how I can write code for a Java client (i.e. outside of a web application) that can reference the JNDI datasource provided by the application server.
Sun Application Server的端口都是默认端口。在服务器配置中有一个名为jdbc / xxxx的JNDI数据源，但我注意到Web应用程序的Hibernate配置使用了名称java：comp / env / jdbc / xxxx。
The ports for the Sun Application Server are all at their defaults. There is a JNDI datasource named jdbc/xxxx in the server configuration, but I noticed that the Hibernate configuration for the web application uses the name java:comp/env/jdbc/xxxx instead.
到目前为止我见过的大部分例子都涉及类似代码
Most of the examples I've seen so far involve code like
Context ctx = new InitialContext();
ctx.lookup("jdbc/xxxx");
但似乎我要么使用错误的JNDI名称，要么我需要配置jndi。要正确指向侦听器的属性或其他配置文件？我有来自Sun Application Server的appserv-rt.jar，里面有一个jndi.properties，但它似乎没什么帮助。
But it seems I'm either using the wrong JNDI name, or I need to configure a jndi.properties or other configuration file to correctly point to a listener? I have appserv-rt.jar from the Sun Application Server which has a jndi.properties inside of it, but it does not seem to help.
这里有一个类似的问题，但它没有给出任何代码/指的是让iBatis自动获得JNDI数据源：从Web容器外部访问数据源（通过JNDI）
There's a similar question here, but it doesn't give any code / refers to having iBatis obtain the JNDI Datasource automatically: Accessing Datasource from Outside A Web Container (through JNDI)
推荐答案
我被困在这完全相同的问题。我写了一个小教程。基本上，您必须创建自己的DataSource对象实现，并将它们添加到您自己的自定义初始上下文中。这里有一些源代码示例：
I got stuck on this exact same problem. I wrote a small tutorial. Basically you have to create your own implementation of the DataSource objects and add them to your own custom initial context. There are source examples here:
