数据源

修改context.xml文件

<Context reloadable=“true”>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Resource name=“jdbc/oracleds” auth=“Container”
type=“javax.sql.DataSource”
maxActive=“100” maxIdle=“30” maxWait=“10000”
username=“scott” password=“tiger”
driverClassName=“oracle.jdbc.OracleDriver”
url=“jdbc:oracle:thin:@192.168.1.20:1521:ora9”/>
</Context>

使用数据源：
Context context = new InitialContext();
DataSource ds = (DataSource)context.lookup("java:/comp/env/jdbc/oracleds");
Connection conn = ds.getConnection();
