This is a pretty first level error in java....
You have defined the variable name,add....etc... in the upper block & variables in once block are not accessible in the outside block.......
When you are trying to access them outside their scope .....compiler is unable to find them & thus the error that can not resolve symbol name, add.......
Error is in the lines
<input type = "text" name = "name" value= "<%= name%>"
<input type = "text" name = "add" value= "<%= add%>"
You can't access name & add variable here........

Make your variables in scope.
<html>
<head>
<title>Employee regs
</title>
</head>
<%@ page language="java" session="true" import="java.sql.*" %>
<body>
<form name ="form2" method = post action ="http://172.16.0.8:8080/check/lib/edit.html">
<%
String sea = request.getParameter("search");
String name = "";
String add = "";
String email = "";
String phone = "";
try
{
try
{ Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}
catch(ClassNotFoundException e)
{ out.println(e);
}
String dbURL = "jdbc dbc:li";
Connection dbCon;
dbCon = DriverManager.getConnection(dbURL);
String query = "Select * from userde where name ="+"'"+sea+"'";
Statement stmt = dbCon.createStatement();
ResultSet rs = stmt.executeQuery(query);
while(rs.next())
{
name = rs.getString(1);
add = rs.getString(4);
email = rs.getString(5);
phone = rs.getString(6);
out.println(name);
out.println(add);
out.println(email);
out.println(phone);
out.println("Searched Successfully!!") ;
}
dbCon.close();
stmt.close();
}
catch(SQLException e)
{ out.println("fucking problem " +e);
}
%>
<input type = "text" name = "name" value= "<%= name%>"
<input type = "text" name = "add" value= "<%= add%>"
<input type = "text" name = "email" value= "<%= email%>"
