Re: Coldbox and ColdSpring How to?
One of the minor side-effects of the way ColdSpring easily handles more and more complexity is that I found my ColdSpring XML file got out of control unless I took an organised approach to the layout. My first few ColdSpring sites had about 20 CFCs or so to manage, and without thinking much, I'd just add a new CFC to the bottom of the XML and that would be fine. But then i built a site that had many more CFCs than that, and i found my XML file got unmanageable. I was getting errors because i was duplicating the XML definition of CFCs and omitting some altogether.I found i had to be more organised than the XML equivalent of the shoebox filing system. I tried putting the CFCs into the XML file in alphabetical order, and that didn't really work. It improved things a bit, but what worked most was to put CFCs related to different parts of the application together - all the USER cfcs together and all the CONTENT cfcs together and all the CATALOG cfcs together etc. With comments between the sections of the XML file, so they are easy to find. THEN Coldspring showed its magic. It happily handled the management of hundreds of CFCs, all their dependencies, locations, how they are to be instantiated, and all i ever had to do in a calling page was something like: cfset UsersDAO = application.beanfactory.getbean(UsersDAO) and i never had to worry again about how to instantiate it, where it was, what other cfcs it depended on, where to find them, whether parameters or other objects were required in the init() method, etc. If i ever change my hard drive layout - move my CFCs around - there's only one file that ever needs to know where to find them - the coldspring XML file. As i said, MAGIC! All i have to do is 'hey Coldspring - give me a UsersDAO object' and it knows what to do , and just does it!

Another useful trick is to use the import directive so you can break your ColdSpring XML file down into multiple files with each file containing CFCs for a specific part of the application, then you have: import resource=user-beans.xml/ import resource=content-beans.xml/ import resource=catalog-beans.xml/ Each imported file must be a syntactically complete ColdSpring XML file, i.e., must contain beans .. /beans and some bean definitions. -- Sean A Corfield -- (904) 302-SEAN Railo Technologies US -- http://getrailo.com/ An Architect's View -- http://corfield.org/ If you're not annoying somebody, you're not really alive. -- Margaret At ~| Want to reach the ColdFusion community with something they want?

Re: Coldbox and ColdSpring How to?
Thanks Mr Corfield, perfect. last question I promise (fingers crossed). I am just playing with ColdSpring, however maybe I am missing the point with what I have done in the example so far. this could have been all done in the init() method or I could have extended the CFC or I could have passed in the details from config CFC without ColdSpring. I could have also cached my CFC in CB or on app start. I have read the docs on ColdSpring it seems to be adding an easy to use system yes, but an extra layer to my app also. what are the benefits of working this way, am just ignorant having never used it or AOP before in CF.

Coldbox and ColdSpring How to?
I am trying to get my head around ColdBox and ColdSpring (manly ColdSpring) so please be kind and any example code with comments would be much appreciate. My question I have a CFC called model/common.cfc This CFC contains all my SQL code that interacts with the database. However in common.cfc I currently use the following code inside common.cfc on init() to get my DNS details... ! CONSTRUCTOR cfproperty name=dsn type=coldbox:datasource:DBDetails scope=instance!---inject datasource--- cfscript instance = structnew(); /cfscript cffunction name=init access=public returntype=any output=false cfargument name=dsn type=any _wireme=coldbox:datasource:DBDetails / cfreturn this /cffunction I can then call it anywhere inside common like so #instance.dsn.getName()# Now this works fine, but wanting to expand my knowledge I have decided to introduced ColdSpring (no experience of it before) I understand why I would use an IOC so I wanted to start simple. I want to replace the above code and inject the DNS details into common.cfc and use âoneâ bean for all. I have followed the documentation on CB but am struggling mainly because of my understanding I think.

Re: Coldbox and ColdSpring How to?
Common.cfc has to be managed by ColdSpring for the dependency injection to take place. I.e., you need: bean id=common class=model.Common ... etc ... /bean And you need to get the common bean from ColdSpring wherever you use it. Your XML has the bean named userGateway which doesn't seem right (since you have a property injector method in Common.cfc for userGateway)?
