These are notes from Adobe MAX 2009. The talk was given by Adam Lehman.

First, ColdFusion 9 also introduces the new ColdFusion Builder product, an Eclipse-based IDE “to rule them all”. Because it is based on Eclipse, you can also combine other products, like Flash Builder, so that one IDE gets the job done for everything, whether it is HTML, CFML, JS, Flex, ActionScript, CSS, etc.

ColdFusion Builder also supports some interesting server integration features. You can access ColdFusion Administrator and other functionality right from ColdFusion Builder; you can see and browse all of the databases that ColdFusion has datasources for. With such functionality, you can do cool stuff like auto-generate ORM-based CFCs by pointing it to an existing database table! Now, it doesn’t generate just the bean CFC. It generates the entire service layer: DAO and Gateway beans as well!! Now, this obviously is just a starter step. It’s expected that you’d tweak it from that point. With the Flash Builder integration, you can take this to the next step by also generating ActionScript objects to help with Flex integration as well.

CFML Enhancements

Well, in CF7, they introduced Application.cfc that supported hooks for application events. But now in CF9, there is a Server.cfc with an onServerStart() method for handling that event.

Various other holes have been filled. You can now have nested CFTRANSACTION tags. Error catching now supports “finally”. And looping now supports CFCONTINUE.

Variable level enhancements: You can now pass implicit structures/arrays to tags and functions. Before you had to assign it to a var and then pass it. There is assignment chaining (a=b=c). Direct access to elements of returned arrays (i.e. myFunction()[x] couldn’t be done previously). And, finally, ternary operators! For instance, you can do something like: a = (b<c)?b:c

CFSCRIPT enhancements. Starting in CF9, you can now write 100% script-based code, including classes/components.

CFC enhancements. There is now an explicit LOCAL scope. Instead of doing var myvar=1, you can do LOCAL.myvar=1. What’s more, you can declare a variable with var anywhere in the code, not just at the top. CFCs also support implicit getters/setters by using the CFPROPERTY tag. These are worth using if there is no special handling going on, because they’re 7x faster than your own getters/setters.

Here’s an awesome feature. You no longer have to use CreateObject() to create a CFC. You can use the IMPORT keyword to point to a directory of CFCs and have them be first-class citizens in your code. And you can use the NEW keyword to create CFCs, like user = new User(). Looking more Java-like all the time.

How to convince your boss to upgrade

First, with CFIMAP, you can now access email with IMAP support, such as GMail.

There are many PDF support enhancements. Create PDF packages, add/remove headers and footers, optimize PDFs (down-sample images, for instance), extract text/images, high-quality thumbnails, convert Word documents to PDF.

There are presentation options. The CFPRESENTATION tag will generate PPT files from CFML/HTML content. And you can go the other way: Convert PPT to HTML or Flash. Supports Microsoft PowerPoint ’97 to ’08 and Open Office Presentations.

Spreadsheet support. The CFSPREADSHEET helps you create, read, and merge native Excel spreadsheets. This isn’t just a CSV file. This is a real Excel spreadsheet with formulas and formatting support.

SharePoint integration. Native access to SharePoint data and services (Sites, templates, sub-sites, web parts, and workspaces). You can get lists including data, views, and alerts and querying against lists. Users, permissions, site groups, cross-site groups, security groups, and distribution groups. Build web parts with CFML. Integrate with SharePoint Single sign-on. You may wonder, “Why is this necessary since SharePoint has web services and exposes information as XML?” Because it’s painful. ColdFusion makes it significantly easier and faster.

ColdFusion Server Manager. A Flex-based AIR application that helps you manage multiple ColdFusion servers. And it receives system notifications and alerts. Helps apply settings for multiple servers.

The next generation of applications

Coldfusion 9 ORM functionality. Powered by the Java Hibernate framework, so it is industry standard. Various ormXXX() and entityXXX() functions provide this functionality for you. With this feature, no more SQL is necessary, so apps can be developed faster (and potentially with fewer errors). CFCs will just be automagically saved. But it’s not just a matter of saving time on development; it also makes it so that your app is no longer database-dependent. It can point to any database server and it should just work.

Enhanced caching. ColdFusion is already pretty optimized for speed (esp. between CF7 to CF8). So to get more speed, developers need to use these new caching features. Using cacheGet(), cachePut(), and cacheGetMetaData(), you can save/retrieve objects from a built-in cache. Page fragment caching allows you to have a combination of static and dynamic content on a page. This provides a HUGE performance boost, depending on what you’re doing. For instance, you only want to generate a menu dynamically the first time, but then another area of the page is dynamic every time.

Performance gains. Okay, Adam lied. ColdFusion 9 is actually 40% faster than ColdFusion 8, with no changes to code, just upgrading ColdFusion. CFC creation is 8x faster, method invocation is 3x faster. And UUID creation is 100x faster. These are some huge bottlenecks that have been blown away. There is a performance brief that Adobe will be releasing on ColdFusion 9 in the near future.

Search engine. ColdFusion 9 now includes Apache Solr. Verity is still included, but so is Solr, which is actually even faster than Verity. So you may choose to upgrade to Solr! They even provide a Verity-to-Solr migration utility.

ColdFusion Server API. You can have direct access to ColdFusion services for CFCHART, CFDOCUMENT, CFPDF, CFIMAGE, and more. This makes it even easier to access ColdFusion mail/pdf/images services directly within Flex without having to custom code some ColdFusion code.

What’s more, Flash Remoting is 9x faster. It may arguably be the fastest flash remoting server-side technology around.

There are various JavaScript/Ajax tags, like CFMAP for Google Maps, CFMESSAGEBOX, CFSLIDER, and more. Ajax functionality in CF is powered by ExtJS 3.0 (which is nice, because ExtJS isn’t free anymore, so getting CF9 gets you a copy of ExtJS basically), and JQuery is also supported.

This presentation was very rapid fire, which is testimony to how feature-rich of an upgrade ColdFusion 9 is.

These are notes taken at MAX 2009. This is obviously subject to change before AIR 2 is launched.

Multi-touch gestures. This is especially useful for Flash’s new ability to compile down to iPhone, but it will even work on tablets or laptops that support multi-touch, such as the track pad on MacBooks.

Opening Files. There is now a File.openWithDefaultApplication() method which does just what it says. So you can open data document of any type in its native app from your AIR app, i.e. open a Word document in Word from your AIR app. Executables are blacklisted, such as *.exe, *.bat, or other executables.

File “downloaded”. You can use myFile.downloaded=true to set the bit on a file that will notify the user with a message like, “This file has been downloaded from the Internet. Are you sure you want to open it?” the first time it opens.

Volume Detection. Listen for mounting and unmounting of volumes. Query system for volume info. So this gives you the ability to work with external volumes including optical media or attached cameras.

Native processes. You can start native processes outside of AIR, or even reference it and launch it. This includes passing in arguments and utilizing stdin, stdout, stderr! Now, you can’t use this ability from an app that has been installed straight from an AIR file. You have to have the app in a native installer. This way, someone on a Mac won’t try to run an app that wants to run a Windows executable, or something similar. In the demo, the Mac screenshot process was invoked, and in another demo, Spotlight functionality was invoked and its output was incorporated into the app!

File promises. Ability to tell the OS about files you don’t have yet. Gives you the ability to drag and drop files in cases when they are on the network or Internet.

Listening on a socket. Ability for inter-application communication. Better protocol support (such as FTP). Networking utilities. You just use ServerSocket.bind() and ServerSocket.listen() methods in conjunction with an event listener to act on activity. Demonstrated it with an HTTP proxy app called HTTPeek (on Google Code). Very fast. Handles the socket connection well.

Advanced Networking. Get network information. Support for IPv6. UDP support. A DNS resolver. More coming.

Audio Encoding. Surprisingly, this wasn’t supported before. Now you can encode data directly from the microphone.

Global Error Handling. You can now catch all uncaught errors and error events in your app. This is useful because on a client that does not have the debugger version of Flash, the app will just stop working. With this global error handling feature, you can log the errors to a file or over the network, or do other things.

Accessibility. Functionality from Flash Player 10 will now be supported in AIR. It has 28 accessible Flex components, supporting MSAA (Microsoft Active Accessibility) in JAWS or Microsoft Narrator, for example.

JavaScript Profiling. Can access profiling information via Aptana.

Optimization. Lower memory consumption, lower CPU utilization especially when the app is idle.

Misc. Improved printing. SQLite supports nested transactions. Exit even on shutdown (can now see when the event is not cancelable). Various WebKit enhancements.

Flex 3 will work for AIR 2, but Flex 4 with Flash Builder 4 will be a cleaner, more set up approach for developing AIR 2. You’ll have to overlay AIR 2 SDK on your Flex Builder 3 installation if you want to develop for AIR 2 in Flex 3.

Like I have done in the past, I am declaring radio silence today. I will not be check my feeds, look at any Apple news sites, or check my personal email until I can view Apple’s video stream of the WWDC keynote. 

You can view the MacRumors WWDC 2008 Spoiler Free news page if you want to do the same.

The following are notes from the XML 101 class at Adobe MAX 2007. I’m skipping over the extremely basic XML principles and covering the more interesting stuff.

When use XML nodes over attributes? Attributes are good for set, simple values. If you have complex values, multiples of a particular entry, or you want more extensibility, use nodes for XML.

The presenter demonstrated using DTDs over XML Schemas. The DTDs use a very specific grammar that is not even XML-ish. It’s kind of yesterday’s XML descriptor. Nowadays, better to use XML Schemas, which are actually XML defining XML. Both are ugly in my opinion, and XML Schemas are more verbose (as XML usually is), but you might as well go with the latest, most accepted convention, which is the XML Schema approach.

By using DTDs and XML Schemas, apps can be cognizant of the structure of your XML language. Even from a developer’s viewpoint, this can be useful when editing XML within an IDE.

The real fun part is formatting the XML with XSL (eXtensible Stylesheet Language). Supports loops, conditional logic, and other processing. Think of it as CSS on steroids, for XML. With XSL, you can transform XML to HTML, or PDF, or other fun stuff.

XPath is the heart of XSL processing. Allows you to traverse the XML document and find exactly what you’re looking for, whether it’s a particular node or looping over a group of items (xsl:for-each).

You CAN send the XML and XSL to the client and have the transformation be done client-side. All modern browsers include the XML/XSL engine. But generally it is wiser to do the transformation on the server side.

In my opinion, this approach lowers the value of XSL, because I can just as easily write some CF that will act on the XML. Yeah, I can write numerous XSLs for different presentations (text-only, XHTML, PDF, etc), but I’d have to do the effort of writing different XSL docs for that, when I could just as easily write different CF processors that accomplish the same thing. Unless you are working with a huge number of documents of varying types, XSL may not provide a large enough of an advantage for a language like CF that so easily manipulates XML.

The final step is grabbing XML with Ajax (such as Spry) that will populate document spaces (tables, divs, etc) with the XML data very easily as well. Again, this approach is similar to the CF approach, but with a more JavaScript-heavy slant.
