Enterprise Integration with ColdFusion
Sean A Corfield
Director of Architecture
Macromedia, Inc.
Goals
Explain some of the history behind Macromedia's use of ColdFusion, both on the web and behind it
Show you how Macromedia is using ColdFusion “behind the web” for integration tasks
Inspire you to think outside the “web box” and look for new problems to solve with ColdFusion MX 7
Who Am I?
Senior Architect for Macromedia IT (since mid-2000)
A ColdFusion developer (since late-2001) ...and Java developer (since early-1997)
An advocate of standards and best practices (since birth?)
Agenda
Setting the scene – a brief history of macromedia.com
A look at our Online Store architecture Introducing Oracle Applications (ERP) Additional systems join our Hub'n'Spoke world Evolving our Online Store architecture Upcoming changes and future plans Wrap-up
macromedia.com BC
Before ColdFusion...
macromedia.com was built with BroadVision and Perl
We created flat files full of CSV data and ran batch jobs to move those files around and load them into databases
macromedia.com BC
2001 A ColdFusion Odyssey
Macromedia acquired Allaire I formed Web Technology Group to rewrite
macromedia.com using ColdFusion ColdFusion 5 was the (new) current release We learned ColdFusion on Neo using pre-alpha
builds and then alphas and betas – it was “fun”... We also picked JMS (Java Message Service)
and XML as core technologies for data transfer between the website and the various back end systems, using Java “adapters”
macromedia.com – CFMX 6.0 U3
macromedia.com launched in early March 2003 on ColdFusion MX 6.0 Updater 3
About a dozen ColdFusion applications BroadVision still powered our Online Stores Perl still powered many of the simple information
forms Later that year we launched the Flash /
ColdFusion Online Stores for Europe with BroadVision for non-Flash users
macromedia.com – CFMX 6.0 U3
macromedia.com – CFMX 6.1
We were running Red Sky just before launch (August 2003)
We adopted Mach II as the Web Team standard (2004)
We continued to write more applications (currently around 50 applications, a quarter are Mach II apps)
We launched HTML versions of our Online Stores and rolled them out worldwide (2003-2004)
BroadVision was finally gone Some Perl forms remain (it ain't broke!)
macromedia.com – CFMX 6.1
Online Store Architecture I
Tiered application architecture:• Front end has both Flash & HTML versions
• Business logic implemented with ColdFusion (using the same CFCs, and Mach II for HTML version)
• Back end used Perl scripts to manage fulfilment and settlement functionality
CSV (tab-delimited) files moved by FTP to ERP system
Online Store Architecture I
ERP – Oracle Applications
Rolled out new ERP system (March 2004) Used OAGIS 7.2.1 standard XML for order
management file exchanges (instead of CSV) Still FTP based batch jobs (since everything is
file-based) Some vendors (including OLS) still provided CSV ColdFusion application written to manage all the
XML and CSV file exchanges and automate the FTP processes
ERP – Oracle Applications
Breeze Live Online Sales
2004 also saw Breeze Live become available for purchase online as well as hosted solution
Decided to leverage JMS rather than Online Store method
Sales orders transmitted as XML over JMS in near real time
Developed JMS event gateway for ColdFusion MX 7
Uses exactly the same order processing CFC as batch files
Breeze Live Online Sales
salesforce.com (late 2004)
Implemented sf.com for sales leads Web site captures leads, publishes them
using JMS Web Service adapters (.NET) exchange data
with sf.com JMS used to exchange data between
adapters and other systems: web site, support, marketing, analytics
salesforce.com (spring 2005)
We rewrote all of the .NET adapters in ColdFusion (.NET libraries from the JMS vendor were unreliable)• Rough guesstimate: building adapters in CF is
between four and eight times easier than either Java or .NET based on development times (Java and .NET are about par)
Leverage the CFMX 7 JMS event gateway Leverage improved web service support in
CFMX 7
Internal Order Management
Several internal applications also capture manual orders
Already written in ColdFusion Generated orders as CSV files
Rewrote file generation custom tag to produce XML
Could easily change to use JMS now!
Online Store Architecture II
Replace Perl back end• Use same engine as Breeze Live Online
Sales
• Send all orders as XML over JMS
ERP ColdFusion application does not change!
OLS Architecture II – Web Side
OLS Architecture II – ERP Side
New Order Management
Real time communication between OLS and ERP• Sales orders
• Order status
• Ship confirmation Inside Oracle we publish data in real time
• On triggers / workflow events, we publish recordsets as XML to Oracle AQ queues
• Oracle AQ event gateway (Java) consumes and republishes to JMS using JMS event gateway
New Order Management (cont)
Large attachments processed in the background• Sends URL to async CFML gateway
• Async task fetches document and stores in Oracle Real time communication between ERP & CRM
• Customer details & entitlements published to a single Oracle queue as XML rowsets
• Oracle AQ event gateway consumes, reformats and publishes to two separate JMS topics
• JMS event gateway consumes , parses and stores customer details & entitlements in CRM
The Big Picture
Future Plans
Over time, replace complex custom Java adapters with CFMX 7 JMS event gateways
Consider replacing scheduled tasks that scan directories for files with the built-in CFMX 7 DirectoryWatcher
Enhanced JMS event gateway – supports authentication, per-topic cached publishers, additional “initial context properties”
Conclusion
XML provides a human-readable, self-validating, structured format for complex data – and it's easy to process in CF!• XML beats CSV hands down (duh!)
JMS has reduced latency in data processing and improved the reliability of data transfers within the enterprise
A hub'n'spoke architecture makes it easier to add and replace systems without re-engineering everything else
Conclusion (continued)
Building JMS-based applications can be a complex, time-consuming process (and unreliable on .NET!)
ColdFusion MX 7's event gateways make it easy to build maintainable, robust asynchronous applications• JMS publish & subscribe
• Oracle AQ receive
• DirectoryWatcher
• Asynchronous CFML
