I try to access a database on a Linux server, with
Apache, Tomcat & Postgres.
The servlet should connect to the database, make a
select and display the results in a webpage
My code is the following:
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
res.setContentType("text/html");
PrintWriter out = res.getWriter();
try {
String database = "intvuelos";
String username = "nobody";
String password = "";
Class.forName("org.postgresql.Driver");
con =
DriverManager.getConnection("jdbc:postgresql://10.65.28.12/invuelos",
username, password);
stmt = con.createStatement();
rs = stmt.executeQuery("SELECT numeroempleado,
origen, destino FROM viajes");
out.println("<html><head><title>Consulta de
Datos</title></head>");
out.println("<body>");
out.println("<ul>");
while(rs.next()){
out.println("<li>"+
rs.getString("numeroempleado") + " " +
rs.getString("nombre") + " " +
rs.getString("apellidos"));
}
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{
try{
if(con !=null) con.close();
}
catch (SQLException ignored){ }
}
}
}
****
Please help me if you can
