ColdFusion Manual Configuration & Issues with TCP ports 51011, 51010 and 51800 on IIS and Apache

ColdFusion works by configuring your web server (IIS, or Apache) to execute files with known extensions (.cfm, .cfml, .cfc et al) to run as script. And for doing that ColdFusion comes with a small and important tool called “wsconfig”.

Problem: At times, regardless of operating system and the web server you are using, the ColdFusion installation will fail to configure web-server due to your network settings or firewall/security settings. When running wsconfig tool, you may encounter errors similar to the following:

• Could not connect to any JRun/ColdFusion servers on host localhost.
  • Possible causes:
    • Server not running
      - Start Macromedia JRun4 or ColdFusion server
    • Server running
      - JNDI listen port in jndi.properties blocked by TCP/IP filtering or firewall on server
      - host restriction in security.properties blocking communication with server

Snapshot above shows one of the common scenario when wsconfig will not configure IIS.

Solution: Here is one fail proof solution to complete the installation of ColdFusion and stop worrying about getting wsconfig to… “run”. Yes, you we will not run “wsconfig”. Instead, we will manually configure web-servers and manually create files that are created by wsconfig.

Tag-Team Death Match: Flash & ActionScript V/S HTML5 & JavaScript

Much has been said about HTML5 and its proponent frequently compare HTML5 to Flash. Many of those proponents try to malign Adobe’s Flash in many ways. Neil Webb has already written a perfect article presenting his counter-points to HTML5 proponents.
HTML5 Applications are nothing without JavaScript. Similarly, Flash Applications are nothing without ActionScript.
I don’t wish to talk about how good or bad the features offered by HTML5 are when compared to Flash’s features.
Let’s see if you can use HTML5 in your projects today!

Unable to Receive Email Messages on Your Google Apps Custom Domain?

It happened to me when I added a CNAME record for “codecurry.com”.

Simple solution: I deleted the CNAME and used A Record to point my root domain “.codecurry.com” to my hosting server.

CNAME Records use host-names to point to a server, while an A Record uses host’s IP Address to point to a server.

I have been using Google Apps for email of this account since a year without a glitch. But I had to update this domain’s A Records and CNAME. So instead of changing my A Record, I deleted it and created a CNAME record to point to my hosting server. Too bad, Google Apps didn’t like it. Emails sent to me started bouncing back to senders.

Yes, it is possible to add any CNAME Records  even when using Google Apps Custom Domain Email. So it will work if you add sub-domains hello.codecurry.com or files.codecurry.com. It will simply not work if a CNAME is used for the root domain, as in “.codecurry.com”. The root domain should only be pointed to your host server using A Record.

Hope this will help someone facing this issue with Google Custom Domains.

Installing ColdFusion on IIS 7 + Configure IIS for ColdFusion in Windows Vista and Windows Server 2008

When installing ColdFusion on Vista or on Windows Server 2008 you may receive HTTP 404.3 Error, similar to this one:

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

Additionally if you run ColdFusion Web Server Configuration Tool, you will see a message saying that IIS components are being installed and could take between 2 to 5 minutes of time.

You can resolve this error by making sure that the two required components of IIS are installed on your system. Namely:

1. ISAPI Extensions
2. IIS Metabase and IIS 6 configuration compatibility.
