ColdFusion Developer in Australia

Another example of small error, which can take a lot of time to resolve.

One of my event gateway has stopped working after upgrade and I stumbled across Error invoking CFC for gateway XXX: null error in eventgateway.log file.

After some guessing about the cause of this error and trying to fix this and that bits of code, I have finally checked exception.log file and discovered same error, but it had more details on where to look:

1. "Error","Thread-23","02/02/10","23:29:09",,"Error invoking CFC for gateway XXX: null {ORIGINATORID={CFMLGateway},DATA={{...}}},GATEWAYID={XXX},GATEWAYTYPE={CFMLGateway}}."

2 coldfusion.runtime.AbortException

3 at coldfusion.tagext.lang.AbortTag.doStartTag(AbortTag.java:63)

4 at coldfusion.runtime.CfJspPage._emptyTcfTag(CfJspPage.java:2661)

5 at cfxxxecfc750176571$funcONINCOMINGMESSAGE.runFunction(/var/.../xxx.cfc:19)

So that line 19 of gateway's cfc code had <cfabort> tag, which caused the error.

First ever ColdFusion conference I have attended today in Melbourne (Australia) was not that bad at all ;-) Thanks to organizers, we've got pretty good composition of speakers and topics covered.

I am not going to narrate or comment on what I've heard today at the conference, but there are few things I found interesting to mention:

— CF9 seems to be a seamless upgrade for many users and provides new functionality for rapid applications development (RAD).
— CF9+Solr is the way to go (drop Verity if possible).
— CF Builder can help a lot with RAD even for current CFEclipse users.
— YourKit Java Profiler is a nice tool for your application with memory leaks debugging.
— Git takes over SVN as faster and more flexible version control system.

Ah, yeap, few photos of the event.

While arguing that CF is the best dead language ever in one online community with other geeks, I have found interesting PDF, named Adobe ColdFusion Evangelism Kit and released in 2009 by Adobe.

This document includes several facts and key figures to advocate your prospective clients for CF. In my opinion the best page of whole document is comparison of ColdFusion with Java/JSP, ASP.NET and PHP in terms of development timeframe and cost of ownership.

Are you an experienced ColdFusion developer and you've looked at Flex before and had trouble getting started? Adobe offers FREE full-day, hands-on training session, to build your first Flex application using Flash Builder 4 (beta)! This training is designed to help experienced ColdFusion developers get started in understanding how to add rich UI to existing and new ColdFusion applications.

Does anyone know how to remove EXIF data from image?

It looks like cfimage keeps all EXIF information upon resizing, so produced small thumbnail 75x75 px will be around 20K instead of just 2K because of extra data.

Finally OpenID CFC consumer library has been upgraded to support OpenID 2.0.

All credits for this release go to Richard Davies, who solely made an update and provided it to CF community for free.

New version has been tested using following OpenID providers: 1id.com, Blogger, ClaimID, ClickPass, Flickr, Google, I-name, Identity.Net, MyOpenID, Technorati, Verisign, WordPress, Yahoo and various standalone OpenID servers.

Starting yesterday most of my CF websites are under constant attacks by bots, which are trying to implement SQL injection attack using additional URL parameters.

Since not all applications were developed using CFQUERYPARAM tag and update of all CFQUERY calls will take a long time, simple solution has been developed to block hackers. ( read more on Protect your CF application )

Starting from mid-May my Facebook application (FOAF) was throwing error message "500 POST data is missing in the POST" while I had no changes in the code for ages. A little bit of googling unveiled an error with Facebook Rest Client CFC: ( read more on Facebook Error 500: POST data is missing in the POST )

Today I ran into the following problem while working in CFEclipse:

Error opening the editor.
org.eclipse.jface.text.Document cannot be cast to
org.cfeclipse.cfml.editors.ICFDocument

As a result of further investigation I discovered lack of permissions to a few files on mapped network drive with my spaghetti code.

Tonight I had some time to clean up blogroll for CFDA aggregator and noticed how many CF blogs does not validate their feeds.

While aggregator is setup to fix common errors (null characters, non-standard date format, etc.), from now it will also be counting http errors and checking feeds validity to prioritize data fetching. Therefore I want to encourage you to double check your feeds and its validity.

Another kindly request is to properly categorize blog entries using relevant tags.

For feed validation you can use W3C Feed Validation Service or FEED Validator.

BTW, ColdFusion is a single word for many years already, not Cold Fusion.
