neo-cron.xml corruption issue

ColdFusion , Gotchas , Misc , Server and Hosting 8 Comments »

After New Years - we returned to a sickly server, and something I never came across before - so I thought I'd share this with you all!

Background

Our servers are deployed as Multiple J2EE Instances runnng the latest version of ColdFusion 9.0.1.

When we tried accessing one particular application, we got the following error:

The Cron service is not available.  
This exception is usually caused by service startup failure. Please check your server configuration.

Don't be fooled by the error message, the real issue lies in a corrupted server file.

Turns out the neo-cron.xml file was corrupted.

Blog post 101 and a ColdFusion 101 Series

Best Practices , ColdFusion , Misc , Tips and Tricks No Comments »

To mark the 101st post on my Blog, and to complement my thoughts on what content I wish to publish on my blog in order to keep it current, I have decided that I will be writing some material on the following areas:

  • 101 - ColdFusion variables and scopes, to include complex and simple variable types.
  • 101 - Anatomy of a ColdFusion CFC.
  • ColdFusion by Example - A series of posts that provide examples of some of the most commonly used ColdFusion Tags and Functions grouped by type, with practical examples.
  • Syntax is easy, programming is hard.  A general guide on how to concentrate more on the actual programming side of development rather than getting caught up with the syntax!
It's a tall order, I know, and it'll take discipline in order to keep the momentum going with this, but the idea is to provide some useful output during this process e.g. code snippets \ templates along the way that can be used and altered by anyone (including me) during development.

Festive Blog Addition

Javascript , Misc No Comments »

If you haven't noticed already...

In the run-up to Christmas, I thought it would be nice to add some festive cheer to the "Homepage" of my blog!

For some reason my preference was to add Christmas lights over any other potential effect.  So here it is.

These lights don't just flash either, you can also smash them with your mouse pointer and alter their size.

To alter their size, simply append any of the following options to the URL:

  • ?size=pico
  • ?size=tiny
  • ?size=small
  • ?size=medium
  • ?size=large

NOTE: There are sound clips used when smashing the lights so please ensure your speaker volume isn't too high (especially if you're in the office!!).

<cfhttp/> Connection Failure

ColdFusion , Gotchas , IIS , Misc , Server and Hosting 1 Comment »

I was working on calling a remote template via <cfhttp /> recently and was experiencing a Connection Failure Error.

Scratching my head I proceeded to inspect what was going on in my code and on the wire with Firebug. 

At first I thought I had resolved the issue when I discovered my return type was a complex value (struct) but my elation was quickly drowned by the "CTRL+F5" key combination :-(

Without any luck I decided to consult the WWW.

After a quick search I discovered that it was due to the reponse being Compressed from IIS.  Apparantly the HTTPCompression algorithm used by some versions of IIS is incompatible with ColdFusion (Java).

Workaround

The work-around was to specify additional HTTP Headers telling IIS _NOT_ to use compression for that response.  See below...

<cfhttp 
    url="http://someURL.com/svcs/targetTemplate.cfm?argument1=value1&argument2=value2" 
    method="get" 
    compression="none" 
    result="remoteCallResult" >
            
        <cfhttpparam type="header" name="Accept-Encoding" value="deflate;q=0" />
            
        <cfhttpparam type="header" name="TE" value="deflate;q=0" />

</cfhttp>

OR

<cfhttp 
    url="http://someURL.com/svcs/targetTemplate.cfm?argument1=value1&argument2=value2"
    method="get" 
    compression="none" 
    result="remoteCallResult" >
            
        <cfhttpparam type="header" name="Accept-Encoding" value="*" />
            
        <cfhttpparam type="header" name="TE" value="deflate;q=0" />

</cfhttp>

That should do the trick!
