Subject: Re: JDBC question
Thanks for your help, here attached my servlet.
I'm using win98 with Access 97, and set up a system DSN "Northwind" without
userID and password.
After I run this servlet, I got NullPointException.
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class JDBCServlet extends HttpServlet
{
Connection dbConn;
public void init ( ServletConfig config ) throws ServletException
{
super.init( config );
try
{
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
dbConn = DriverManager.getConnection( "jdbc:odbc:Northwind" );
}
catch ( ClassNotFoundException e )
{
System.out.println( "*****JDBC-ODBC bridge not found" );
return;
}
catch ( SQLException e )
{
System.out.println( "*****SQL exception thrown in init" );
return;
}
}
public void deGet( HttpServletRequest req, HttpServletResponse resp )
throws ServletException, IOException
{
try
{
resp.setContentType( "text/html" );
PrintWriter out = resp.getWriter();
Statement stat = dbConn.createStatement();
ResultSet customers = stat.executeQuery( "select CustomerID,
CompanyName, City, Country from " + "Customers" );
out.println( "<html>" );
out.println( "<head><title>Customer List</title></head>" );
out.println( "<body>" );
out.println( "<h2>Customer List</h2>" );
out.println( "<table border=1>" );
out.println( "<tr><th>Customer ID</th>" );
out.println( "<th>Company Name</th>" );
out.println( "<th>City</th>" );
out.println( "<th>Country</th></tr>" );
while ( customers.next() )
{
out.println( "<tr>" );
out.println( "<td>" + customers.getString( "CustomerID" ) +
"</td>" );
out.println( "<td>" + customers.getString( "CompanyName" ) +
"</td>" );
out.println( "<td>" + customers.getString( "City" ) +
"</td>" );
out.println( "<td>" + customers.getString( "Country" ) +
"</td>" );
out.println( "</tr>" );
}
out.println( "</table>" );
out.println( "</body></html>" );
customers.close();
stat.close();
dbConn.close();
}
catch ( Exception e )
{
e.printStackTrace();
}
}
}
