<table border="0" width="300" align="center" bgcolor="#CDFFFF">
<tr><td colspan=2 style="font-size:12pt;color:#00000;" align="center">
<h3>Search Item</h3></td></tr>
<tr><td ><b>Item Starts With</b></td>
<td>: <input type="text" name="name" id="name">
</td></tr>
<tr><td colspan=2 align="center">
<input type="submit" name="submit" value="Search"></td></tr>

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException,IOException{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";;
String dbName = "register";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "root";
Statement st;
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");
String name = request.getParameter("name");
String query = "select * from item where name LIKE '"+name+"%'";
st = conn.createStatement();
ResultSet rs = st.executeQuery(query);
out.println("<table border='1'><tr><th>Row Num</th><th>Item Code</th><th>Item Name</th><th>Item Price</th></tr>");
while(rs.next()){
out.println("<tr><td>"+rs.getString(1)+"</td><td>"+rs.getString(2)+"</td><td>"+rs.getString(3)+"</td><td>"+rs.getString(4)+"</td></tr>");
