再在jsp中输�?br /><%@ page import="java.sql.*"%>
<%@ page import="java.io.*"%>
<%@ page import="java.util.*"%>
<%@ page import="javax.sql.*"%>
<%@ page import="javax.naming.*"%>
<%
Connection conn;
Statement stmt;
ResultSet rs;
Context ctx=new InitialContext();
DataSource ds=(DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
conn=ds.getConnection();
stmt=conn.createStatement();
rs=stmt.executeQuery("select * from user");
while(rs.next()){
out.println(rs.getString(2)+"
");
}
%>卛_��q�行数据库查�?/p>
