Four easy steps to get the free Railo CFML engine up and running as a J2EE app and linked to a front end Apache.
We'll pretend your application lives in /parth/to/dir/above/web/root/webrootdir this is the DocumentRoot of your Apache and the root (default) context of Tomcat.

ColdFusion 8.0.1 Updater, 64bit Linux Gotcha

Submitted by Falken on Fri, 04/04/2008 - 15:30

Although the download page for ColdFusion lists several different Linux versions (SLES 9 and 10, for instance) if you end up at the actual support matrix for ColdFusion then only a limited sub set of that list is actually supported for 64-bit native (SLES 10.1 only for instance, not 9, and not any other version of 10).

Using the Flex 3 Data Visualisation components with the Flex 3 SDK

I mentioned before ([node:1490]) this was coming but it's online now over at And it all seems, as expected, to work very well.

Submitted by Falken on Mon, 11/26/2007 - 18:33

If during the upgrade of the Gallery2 module for Drupal you see an error like this:

all_user_func_array() []: 
First argument is expected to be a valid callback,
'gallery_admin_settings' was given in /home/drupal/includes/


(and probably an empty or broken Gallery2 module admin. area) then all you need to is go to the theme admin. area and change a setting.
Any setting (I used the 'logo' toggle).
Save it, then change it back and save again.
