Eclipse配置JNDI連接配接池

之前用Eclipse JEE開發web工程，按照網上的一些說法，配置，發現很麻煩。而且每次project重新remove再加載，配置就丢失了。

根據tomcat使用的經驗，嘗試如下方法，就可以解決一次配置，所有同workspace的project都可以随時使用jdni了。

確定Eclipse中配置了tomcat runtime的情況下，在Eclipse中建立第一個web工程的時候，他會自動增加一個Tomcat Server工程，來維護一個tomcat容器，供你的工程來使用。

首先看一下project中的tomcat容器項目的清單：

儲存如下内容為context.xml，增加到Server項目裡Tomcat v5.5 Server at localhost-config裡：

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

測試一下吧，在這個workspace中建立一個web工程，運作，已經可以正常使用jdbc/db02拿到資料庫連接配接池了。
