Hi all
For some reason my servlet isn't showing my data from an sql database onto a web page. I've checked against an example on a jdbc web site and also on a servlet book and the code appears to be correct.
: -
package website;
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ProductServlet extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
res.setContentType("text/html");
PrintWriter out = res.getWriter();
try {
// Load (and therefore register) the Oracle Driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
// Get a Connection to the database
con = DriverManager.getConnection(
"jdbc:odbc:products", "", "");
// Create a Statement object
stmt = con.createStatement();
// Execute an SQL query, get a ResultSet
rs = stmt.executeQuery("SELECT TITLE, DESCRIPTION FROM PRODUCTS");
// Display the result set as a list
out.println("<HTML><HEAD><TITLE>Products</TITLE></HEAD>");
out.println("<BODY>");
out.println("<UL>");
while(rs.next()) {
out.println("<LI>" + rs.getString("title") + " " + rs.getString("description"));
}
out.println("</UL>");
out.println("</BODY></HTML>");
}
catch(ClassNotFoundException e) {
out.println("Couldn't load database driver: " + e.getMessage());
}
catch(SQLException e) {
out.println("SQLException caught: " + e.getMessage());
}
finally {
// Always close the database connection.
try {
if (con != null) con.close();
}
catch (SQLException ignored) { }
}
}
}
HTML web page:
<form action ="/servlet/website.ProductServlet" method="post">
Any help would be very much appreciated.
