Hello everyone, this is a simple little post but it was extremely helpful to me when I found it.
I, for once, was trying to really get my local Mac to work with ColdFusion and CFBuilder, and what I mean by that is to get the debugger working and RDS, etc. Now I have done this before without a problem but only to look at my DB thru RDS on my remote development server (on windows) and not really played much with the debugger.
It is quite a funny thing to say now, but since I've been working a lot with .NET C# and mostly with MVC I have grown to love VS's debugger as they don't have something as nice as cfdump. So as I tried to do this today on my install I kept getting the following error from my CFBuilder.
"could not initialize class com.adobe.rds.core.services.messages"
It was driving me insane and the answer was quite simple, if you are using apache with Virtual Hosts, which I am. Basically there is this one little line inside the mod_jk.conf file that you need to add to your VirtualHost entries, for me it was the localhost definition, just like the person I received the answer from.
