tomcat 5.5连接池配置，如何让工程为默认工程

复制代码 代码如下:

<Context docBase="C:/Program Files/Apache Software Foundation/Tomcat5.5/webapps/FengYue" path="" debug="0" reloadable="true" privileged="true">
<Resource type="javax.sql.DataSource"
password="maxtie17061706"
driverClassName="oracle.jdbc.driver.OracleDriver"
maxIdle="2"
maxWait="5000"
username="maxtie"
url="jdbc:oracle:thin:@192.168.0.13:1521:mmis"
maxActive="4" />
</Context>

复制代码 代码如下:

<Context docBase="C:/Program Files/Apache Software Foundation/Tomcat5.5/webapps/FengYue" path="" debug="0" reloadable="true" privileged="true"></Context>

复制代码 代码如下:

InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:comp/env/aaa/OracleDS");
conn = ds.getConnection();
