Railo adds a cluster scope

Mon, 07 Jul 2008 09:48:00 -0400

Railo introduced yesterday the cluster scope. In a nutshell, you can register all servers in a cluster and Railo will automatically sync the scope across all nodes. The caveat at the moment is that it only supports simple types (simple values, arrays, structs, queries), but not CFCs and Java Objects.

cflocation vs getPageContext().forward() = java.lang.OutOfMemoryError

Mon, 14 Apr 2008 23:39:00 -0400

How can help me with this? My home page was throwing some "java.lang.OutOfMemoryError : Java heap space" errors and I traced it down to a getPageContext().forward("/blog")...

It turns out that after I switched it per a <cflocation url = "/blog"> the error went away.

I also used the CF8 built-in monitor and confirmed that my jrun never ran out of memory; I've always had at least 100-200mb of available JVM memory ...

So, is it so wrong to use server-side relocation? I've been using it for years and never ran into this problem...

Can anyone shed some light?

Speaking at the NYCFUG

Mon, 14 Apr 2008 22:51:00 -0400

I will be speaking at the New York ColdFusion User Group this Wednesday, April 16, with the topic of "AJAXify Your ColdFusion Applications". I promise it will be fun, a good learning experience, and perhaps we may even go out afterwards and have some drinks.

There will be tons of nice give-aways:
1 x Ticket to CFUNITED ($999 Value!)
2 x jQuery Reference Guide
2 x Learning jQuery: Better Interaction Design and Web Development with Simple JavaScript Techniques
2 x Tickets to Flex Camp Wall Street
1 x FusionDebug License....

They're all excellent... I love jQuery and CFUnited is the most popular CF event of the year .... hope to see many familiar faces, so don't miss it.

ColdExt: Another ColdFusion wrapper for EXT

Thu, 06 Mar 2008 20:38:00 -0400

After blogging about Dan's great EXT cf wrapper, I ran across another one today: ColdExt.
It looks great as well, so how about Dan and Justin join efforts instead of doubling work...?

ColdFusion Wins Jolt For Best Web Development

cfext: ColdFusion wrapper for EXT

Wed, 05 Mar 2008 20:33:00 -0400

Dan Vega has been working on ColdFusion custom tag wrappers for EXT, and let me tell you, it looks pretty amazing.

Ext is an EXTremely powerful JavaScript library which I mostly use to develop RIA and heavy desktop-like applications. However, CF8 ships with YUI and EXT for all dhtml and Ajax behind the scenes, so you see where this is going ... There's no easy way to upgrade the Ext version shipped with CF8, and Ext 2.0 has so many more features and improvements...

So check out Dan's cfext at RiaForge or some examples on his blog: forms, layouts, ...

New Faces at CFUnited 2008

Wed, 09 Jan 2008 00:17:00 -0400

This year's CFUnited is going to be great again... they added more tracks and consolidated the frameworks conference into it.

I want to publicly congratulate two of my very talented friends, which I have seen grow the last couple of years and I'm proud to speak with them at CFUnited this year. Luis Majano, author of ColdBox, will be presenting ColdBox 101; and Tom de Manincor, who I have the pleasure to work with at ichameleon/group/, will be presenting on leveraging databases.

I will be speaking at CFUnited Europe: Embrace Factories and ColdFusion Powered Ajax; as well as the traditional conference in D.C: RIA Security and Real time data manipulation with SQL.

Hope to see you all there.

Updated 02/2008: I will no longer be speaking at CFUnited after the date change. Unfortunately, it conflicted with another conference. I will miss you all.

New York ColdFusion User Group (NYCFUG) revamped

Amazing news for the residents of New York: two of my good friends and phenomenal talented friends are taking over the NYCFUG. Ben Nadel and Clark Valberg are replacing Judith and Michael Dinowitz who after ten years fairly deserve a break.

Congratulations New York. Read more about it at Ben's blog.

ColdBox Nightly Builds, courtesy of ANT

Tue, 06 Nov 2007 17:27:00 -0400

ColdBox nightly builds are now available at http://www.coldboxframework.com/downloads/nightlybuild/coldboxNB.zip

It was easily accomplished using ANT, not sure why we didn't do this before.

Enjoy.

ColdBox Beta 2: Flex/AIR Integration comments

Tue, 30 Oct 2007 23:35:00 -0400

When I first read Luis's entry on ColdBox Beta 2: Flex/AIR Integration this is pretty much that immediately went through my head ...

Gotta be honest: at first I didn't buy into it... You have to be careful on separating your logical layers... if ColdBox is a front-controller, why would a Rich Front End talk to it? It should talk to your Service Layer... and your Service Layer doesn't need ColdBox ...

However, after talking to Luis I discovered, what if, what if you make ColdBox become your enhanced service layer manager? What if your ColdBox Handlers become part of your Service Layer API? What do we have? We have a Service Layer with built-in environmental settings, logging, error handling, event interception and chaining, you name it ... Now it all makes sense...

This is good; real good ... perhaps you'll see a full 60 or 90 minutes presentation on this at CFUnited or CF.Objective() 2008.

Keep it up.

Mon, 29 Oct 2007 23:22:00 -0400

That's right. If you're planning to speak at CFUnited 2008, tomorrow is your deadline. If you don't plan to speak, you can still suggest topics or speakers.

I just submitted a few topics, including but not limited to advanced framework development, enhanced service layers for ria's, ria's data security, db real time data manipulation, some facebook secrets, and more ...

See you at CFUN08.

ErrorDetail I/O Exception: peer not authenticated

Mon, 29 Oct 2007 23:01:00 -0400

If you ever see the following error when performing a cfhttp call:

ErrorDetail I/O Exception: peer not authenticated
Filecontent Connection Failure
Mimetype Unable to determine MIME type of file.
Statuscode Connection Failure. Status code unavailable.

It means that ColdFusion is trying to connect to a secure socket layer, but unfortunately, it can't.

So here's the situation, we launched a huge campaign and everything worked on the local environment. There's this one piece where Flash had to connect to a 3rd party's API and post some data using sendAndLoad. The 3rd party has a /crossdomain.xml allowing remote calls, therefore that will not be the problem when it breaks... Amazingly, everything worked from the IDE, but not when published... Still can't figure it out, but we're already late and I need a solution ... I know Flash can connect to my ColdFusion back-end, so I choose to write a proxy ... really simple, loop over every item in the form scope and create a cfhttpparam for it... I write it and deploy in about 3 minutes. It does not work!

Why? cfhttp cannot connect to the 3rd party ... I notice that they're using a 256bit encryption, which I cannot recall, but I might have read somewhere that it won't work with cfhttp. Perhaps I'm wrong, but I had no time to research ... The point is, cfhttp will not connect to that server.

When I google'd the error, thankfully, the first result was from my respected friend Steven Erat. It's a 3-year-old entry showing how to import a certificate to ColdFusion MX, but it still applies.

I followed step by step his instructions, and 10 minutes later my ColdFusion server was connecting to the 3rd party, effectively proxying the Flash RPC call.

Next step now is to find out why I could not connect directly, but my client and I can sleep tonight.

Thanks Steven.
