Hi,
I am trying to make a simple jsp program which eneters data eneterd by user in an html form called main.html.
This is the code for main.html
[code]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Benthic_query </TITLE>
</HEAD>
<BODY>
<form METHOD = POST ACTION="dataConnection.jsp">
Enter the name of the new table: <input type = text name = table_name size= 30>
<br>
Enter the number of the table: <input type = text name=table_number size=10>
<p> <input type = Submit>
</BODY>
</HTML>
And here is the code for dataConnection:
[code]
<%@ page import="java.sql.*" %>
<%@ page import="javax.servlet.*" %>
<%@ page import="javax.servlet.http.*" %>
<%
Connection conn = null;
try
{
String query = "insert into benthic_query values('"+name+"', '"+number+"')";
String userName = "root";
String password = "abc";
String url = "jdbc:mysql://localhost/test";
String name= request.getParameter("table_name");
String number = request.getParameter("table_number");
Class.forName ("com.mysql.jdbc.Driver").newInstance(); //Loading the driver
conn = DriverManager.getConnection(url, userName, password); //connect the appropriate driver to the database
System.out.println("Connection opened successfully");
Statement stmt = conn.createStatement (); //Statement object sends the SQL statement to the DBMS
stmt.executeUpdate ("query"); //executeQuery will return back some rows, executeUpdate does not return any rows
stmt.close();
System.out.println("Connection opened successfully");
}
catch (Exception e)
{
System.err.println("Cannot connect to the database");
}
finally
{
if(conn != null)
{
try
{
conn.close();
System.out.println("Database connection closed successfully");
}
catch (Exception e)
{
}
}
}
// response.sendRedirect("success.htm");
%>
<html>
<body>
<p> <a href = "thanks.html">CONTINUE </a> </p>
</html>
</body>
And I am getting the following error as soon as I hit the submit button in main.html
exception org.apache.jasper.JasperException: Unable to compile class for JSP
