<%@ page import="java.sql.*;"%>
<%@ page session="true"%>
<%!String un,per=null;%>
<%
per=(String)session.getValue("per");
if(per==null)
{
}
else
{
out.println(per);
}
un=(String)session.getValue("un");
Connection con;
Statement st;
ResultSet rs;
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
con=DriverManager.getConnection("jdbc:mysql://localhost/experience","root","");
st=con.createStatement();
/*if(!isNull(per))
{
rs=st.executeQuery("Select EmpName from empdata");
}*/
}
