jsp代码的保护问题！

jsp不加密,所有页面的代码是外露的.如下:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<jsp:useBean id="conn" scope="page" class="XSQL.XSQL" /><%
        String  sS1="";
String  s2 ="";
String  s3="";

String sSQL = "";
ResultSet rs = null;

sSQL = "select * from S_tbl ";
     rs = conn.ExeQuery(sSQL);
   if(rs.next())
rs.close();
}
