    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    <%
    obj.show();
    %>

    here there is error :
    Multiple annotations found at this line:

    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;

    //import com.sun.org.apache.xml.internal.resolver.helpers.P ublicId;

    //Call_OpenApp.java program
    public class Call_OpneApp
    {
    public String show()
    {
    OpenApp obj = new OpenApp();
    System.out.println("Enter Application:");
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String app = null;
    try
    {
    app = br.readLine();
    }
    catch (IOException e)
    {
    System.out.println("Error!");
    System.exit(1);
    }

    obj.process(app);
    return app;
    }
    }

    You should use import property of the <@page > directive to import the class: Call_OpneApp.Call_OpenApp

    Really???? Can you kindly explain it?
    Multiple annotations found at this line:
    - Undefined type:
    Call_OpneApp.Call_OpenApp
    You must refer it in the proper file to let server know, where to find the class file.
