Integrating CFML with ASP.NET Vince Bonfanti President New Atlanta Communications, LLC
Introduction • Vince Bonfanti • President and co-founder of New Atlanta • ServletExec, Java Servlet/JSP engine (1997) • JTurbo, JDBC driver for MS SQL Server (1998) • BlueDragon, CFML/JSP server (2002) • Soon to be .NET-based • vince@newatlanta.com • Mention CFUN on subject or message body
Topics • What is the .NET Framework? • compare/contrast to Java • What is ASP.NET? • What is BlueDragon for .NET? • How do we integrate CFML pages into ASP.NET web applications? • Why deploy CFML on .NET servers?
.NET Framework Overview • The new way to program on Windows, replacing C/C++ and Visual Basic • Installed as a standard component of Windows 2003 Server, can be installed on Window NT/2000/XP • Primarily useful for server-based applications, can also be used for client (desktop)
.NET Framework Goals • Object-oriented, type-safe, garbage-collected, secure, etc. • Increases programmer productivity and improves application reliability, especially for complex server-based enterprise applications • Similar goals as Java (without write-once-run-anywhere) • Similar methods to achieve those goals
.NET Framework Components • Common Language Runtime (CLR) • like Java Virtual Machine (VM) • Microsoft Intermediate Language (IL) • like Java byte code • .dll (assemblies) or .exe versus .class or .jar • .NET Framework Class Libraries (FCL) • like Java class libraries • Multiple programming languages • C#, Visual Basic.NET, Managed C++, J#
… C# VB.NET J# … JRun WebLogic WebSphere … Windows Solaris Linux .NET versus Java Java byte code (VM) IL (CLR) Windows • single platform • single vendor • higher platform integration • lower complexity • lower cost • multi-platform, multi-vendor • lower platform integration • higher complexity, higher cost
ASP.NET Overview • The way to write web applications and web services in .NET • Can use any .NET programming language • Only runs on Microsoft IIS web server • Pages are compiled (like JSP) • Unique concepts • Event-driven versus top-to-bottom execution • Code-behind files to separate logic from UI • Controls are the key component technology
ASP.NET Web Applications • An IIS web site or virtual directory • .aspx web pages or .asmx web services • Optional components • One global.asax file (like Application.cfm) • One or more web.config configuration files • Inherits from machine.config • User controls in .ascx files • A /bin directory for assemblies (also GAC) • HttpHandlers and HttpModules • Web content files (.htm, .css, .gif, etc.)
ASP.NET Demo • Simple web page (hello.aspx) • Simple web server (hello.asmx) • Control and event handling (declarative.aspx) • Control and event handling (codebehind.aspx, codebehind.vb)
hello.aspx <%@ Page Language="vb" %> <html> <head> <title>Simple ASP.NET Page</title> <script runat="server"> Sub SayHello() Response.Write( "Hello, World!" ) End Sub </script> </head> <body> <% SayHello %> </body> </html>
hello.asmx <%@ WebService Language="vb" Class="Hello" %> Imports System Imports System.Web.Services Public Class Hello : Inherits WebService <WebMethod()> Public Function SayHello() As String Return( "Hello, World!" ) End Function End Class
declarative.aspx <%@ Page Language="vb" %> <html> <head> <title>ASP.NET Declarative Example</title> <script runat="server"> Sub Page_Load( Sender As Object, e As EventArgs ) Message.Text = "Hello, World!" End Sub </script> </head> <body> <form runat="server"> <asp:Label id="Message" runat="server"/> </form> </body> </html>
codebehind.aspx <%@ Page Language="vb" Src="codebehind.vb" Inherits="example.CodeBehind" %> <html> <head> <title>ASP.NET CodeBehind Example</title> </head> <body> <form runat="server"> <asp:Label id="Message" runat="server"/> </form> </body> </html>
codebehind.vb Imports System Imports System.Web Imports System.Web.UI Imports System.Web.UI.WebControls Namespace example Public Class CodeBehind : Inherits Page Protected Message As Label Protected Sub Page_Load( Sender As Object, e As EventArgs ) Message.Text = "Hello, World!" End Sub End Class End Namespace
web.config • Used to configure ASP.NET applications • Application initialization parameters • Authentication and authorization • Compilation defaults • Session data storage • Debug and trace settings • Can be multiple web.config files • One per directory, inherit from parents • All inherit from machine.config
web.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation defaultLanguage="vb" debug="false"/> <sessionState mode="InProc“ stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="20" /> <httpHandlers> <add verb="*" path="*.cfm" type="com.newatlanta.bluedragon.HttpHandler,BlueDragon"/> </httpHandlers> </system.web> </configuration>
HttpHandler • Custom (user-defined) components (.NET objects) that process HTTP requests • Can be written in any .NET language • Requests are mapped to HttpHandlers via directives in web.config • .aspx pages are compiled to HttpHandlers • HttpHandlers are like Java servlets • JSP pages are compiled to Java servlets
HttpHandler Example using System.Web; namespace Example { public class HelloHttpHandler : IHttpHandler { public void ProcessRequest( HttpContext context ) { context.Response.Write( “Hello, World!” ); } } }
BlueDragon for .NET • BlueDragon.NET is a CFML runtime that is implemented as an HttpHandler • The BlueDragon.dll assembly can be placed either in the ASP.NET application /bin directory, or the GAC • Configured via web.config or machine.config to route *.cfm page requests to BlueDragon.dll
Integrating CFML into ASP.NET • Use BlueDragon.NET to deploy CFML pages in ASP.NET web applications, side-by-side with .aspx pages and .asmx web services • Share Application, Session, and Request scope variables • Use CFOBJECT to access .NET objects • Use ASP.NET controls in CFML pages • Write CFX tags in any .NET language
BlueDragon.NET Demo • BlueDragon.NET configuration • Hello.cfm • BlueDragon admin console • ASP.NET calendar control
Why CFML on .NET? • Performance • .NET CLR versus Java VM • ADO.NET versus JDBC • Scalability: take advantage of Windows 2003 Server clustering • Native Windows platform integration • Fast, reliable COM integration • Migration to ASP.NET • Another platform alternative for ISVs
