运行环境：MyEclipse8.5+Oracle 11g
在WEB-INF/lib文件夹下的JDBC驱动：
ojdbc5.jar;
ojdbc5_g.jar;
ojdbc6.jar;
ojdbc6_g.jar;
在META-INF文件夹下的数据源配置文件context.xml:
<Context reloadable="true">
<Resource name="jdbc/bookstore" auth="Container"
type="javax.sql.DataSource" driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:orcl"
username="scott" password="tiger" maxActive="200" maxIdle="30"
maxWait="-1"/>
</Context>
JSP文件的连接语句：
Context ctx=new InitialContext();
DataSource ds=(DataSource)ctx.lookup("java:comp/env/jdbc/bookstore");
Connection conn=ds.getConnection();
在这一句报错：
