Building a ColdFusion Administrator Interface in Flex

This presentation, led by Theo Rushin, Jr., explores the ColdFusion Administrator API and demonstrates how to build a user-friendly interface in Flex 2. It covers the functionality of the ColdFusion Administrator API, which allows developers to perform administrative tasks programmatically. Attendees will learn how to integrate Flex with ColdFusion components via RemoteObject service, providing an efficient approach to data management. Gain insights into best practices and common pitfalls, with opportunities for Q&A.

  1. Building a CF Administrator Interface in Flex Theo Rushin, Jr. rushint@yahoo.com Senior Web Application Developer World Singles and DoubleBlack Technologies

  2. About Me • Application Developer and Trainer Since ‘85 • ColdFusion Developer Since ‘99 • Flash Developer Since ’99 • Flex Developer Since ‘05 • Also work with SQL, JavaScript, HTML, and CSS • Currently working for WorldSingles - a subsidiary of NicheClick Media (http://nicheclick.com/index.html)

  3. What We Will Cover Today • What is the ColdFusion Administrator API? • Using the CF Admin API • Building the Flex 2 Interface • Summary • Learn More • Q & A

  4. What is the ColdFusion Administrator API?

  5. What is it? • It allows you to perform most ColdFusion MX administrator tasks programmatically. • In ColdFusion MX 6.x you could use the “undocumented” ServiceFactory to programmatically access ColdFusion’s administrator tasks. • In ColdFusion 7.x you can use the Administrator API, a set of CFCs that offer a formal and secure way of accessing that functionality.

  6. Why use it? • You could give developers the ability to perform certain administrator tasks without having to give out the single CF Administrator password featured in ColdFusion 6.x – 7.x. • Refresh Trusted Cache • Maintain Datasources • Refresh WebServices • Shared Hosting • ColdFusion 8 is still in Beta (as of 7/10/2007)

  7. Where to find the CF Admin CFCs? The ColdFusion Administrator API exists as a set of CFCs located in the [coldfusion_webroot]/CFIDE/adminapi/ directory.

  8. CF Admin API CFCs (cont.)

  9. What are the CF Admin Methods? You may introspect the ColdFusion Administrator API cfc’s by entering http://[webserver]/CFIDE/adminapi/[apicfc].cfc in you browser’s address bar.

  10. CF Admin API Methods (cont.)

  11. Using the CF Admin API

  12. Accessing a Component • Accessing an object … • … using CFML <cfsetadminObj = createObject("component","cfide.adminapi.administrator")> • … using CFSCRIPT adminObj = createObject("component","cfide.adminapi.administrator");

  13. Calling a Method • Calling a method … • … using CFML <cfset adminObj .login(“mycfadminpassword”)> • … using CFSCRIPT adminObj.login(“mycfadminpassword”);

  14. Demo – ColdFusion Show a simple ColdFusion page that allows you to set your IP address for debugging.

  15. Building the Flex 2 Interface

  16. Calling your ColdFusion Component • Use the RemoteObject service to invoke your ColdFusion cfc methods • The RemoteObject uses AMF (Action Message Format), a binary encoding format, over HTTP. • AMF is faster and leaner than using a standard HTTP or WebService call.

  17. Calling your ColdFusion Component (cont.) • RemoteObject service example; • <mx:RemoteObject id="srv" source="samples.data.EmployeeService"> <mx:method name="addEmployee"/> </mx:RemoteObject>

  18. Working with the result data • Most methods return simple data types. • Some methods return more complex data types such as arrays. • Your ColdFusion code should return more complex data types such as structures and arrays that can contain result data or error messages.

  19. Demo – Flex Show a simple Flex 2 application that allows you to maintain various datasources.

  20. Summary • Pros: Developers have access to most of the ColdFusion Administrator features through code. • Cons: Developers have access to most of the ColdFusion Administrator features through code. • Encapsulate your code using CFCs • Use ColdFusion Try/Catch blocks to capture any possible errors. • Use Flex RemoteObject calls to access your components. • It’s easy!!!
