Eclipse配置JNDI连接池

之前用Eclipse JEE开发web工程，按照网上的一些说法，配置，发现很麻烦。而且每次project重新remove再加载，配置就丢失了。

根据tomcat使用的经验，尝试如下方法，就可以解决一次配置，所有同workspace的project都可以随时使用jdni了。

确保Eclipse中配置了tomcat runtime的情况下，在Eclipse中创建第一个web工程的时候，他会自动增加一个Tomcat Server工程，来维护一个tomcat容器，供你的工程来使用。

首先看一下project中的tomcat容器项目的列表：





保存如下内容为context.xml，增加到Server项目里Tomcat v5.5 Server at localhost-config里：

<?xml version="1.0" encoding="UTF-8"?>

测试一下吧，在这个workspace中新建一个web工程，运行，已经可以正常使用jdbc/db02拿到数据库连接池了。
