servlet with weblogic

hi everyone....

When I'm running this program on weblogic server8.1

import java.io.*; import java.sql.*; import javax.servlet.*; import javax.servlet.http.*; class DataInsertion extends HttpServlet { public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException, IOException { res.setContentType("text/html"); PrintWriter out=res.getWriter(); String url="jdbc:oracle:thin:@localhost:1521:xe"; Connection conn; ResultSet rs; try{ Class.forName("oracle.jdbc.driver.OracleDriver"); conn=DriverManager.getConnection(url,"system","oracle"); Statement stmt=conn.createStatement(); String qry="insert into emp values('101','ram','design','12000')"; int i=stmt.executeUpdate(qry); if(i!=0){ out.println("The record has been updated"); } else{ out.println("Sorry! Failure"); } rs=stmt.executeQuery("select * from emp"); while(rs.next()){ out.println(rs.getInt(1)+"\t"+rs.getString(2)+"\t"+rs.getString(3)+"\t"+rs.getInt(4)); } rs.close(); stmt.close(); conn.close(); }catch(Exception e){ System.out.println(e); } } }

this error shown...
