Writing a re-usable business function with ColdFusion 8

and then make it distributable to virtually any web server platform (say, for windows, IIS (5x,6x,7x?); for unix/linux flavor, Apache). Some of you may have thought of this or even have been there done that. Off my head, I'm thinking: a) the business function; b) a 'connector' to the target web server?  Or better, if the web server is J2EE-compliant then it can execute CF code right away but how many web servers are at this level in the market now? a royal question... (Am really wondering and talking loud...) Thanks.

I'm not sure what you're asking but if you write your application in CFML it'll run on all of those yes, by magic. -- Tom Chiverton **************************************************** This email is sent for and on behalf of Halliwells LLP.

> Sorry, I forgot to add, without cf8 server package. So, without any CFML engine, Railo/OpenBD etc., what are you trying to achive ? You could use CFML to template an AJAX front end, for instance, but that still leaves you stuck for the backend. -- Tom Chiverton **************************************************** This email is sent for and on behalf of Halliwells LLP.

>> standalone business function The key word here is Flexibility.  Probably in essence, there are two big groups of web programming languages: java-based (CFML etc.) vs. Microsoft-based (asp, asp.NET etc.).   And if my understanding is correct, any asp code would run under IIS web server without anything else; As for asp.NET, I don't know.  Now, for java-based code for web use, like CFML, the usual route is to use Adobe's CFML engine.  But you brought up an interesting option of using free CFML-compatible engine, however, I have some concerns and before I get into that, let me say, here the business case is, try to distribute a business function built in CF to your potential customers or whoever else (hence, the few requirements of installing this and that the better, naturally the more dependency the less reliability...). Now, what if there's some free and light J2EE component, that be easily plugged into any web server, then, what?  maybe, any compiled cfml code (java bytecode) can run under such a web server environement, a probable yes?  And what's this option's key benefits if it's available? a) performance probably would be good because of less overhead (not implying cfml-compatible engines are not); b) customers are more likely receptive to it? Thanks.

You could, GPL permitting, packacge your application together with OpenBD and ship it as a single 'unzip and run' file. -- Tom Chiverton **************************************************** This email is sent for and on behalf of Halliwells LLP.

----- Excess quoted text cut - see Original Post for more ----- Thank you for the good info.  I now dug up some info on OpenBD, one version 11MB (this one seems more applicable to this case), another 24MB, ahe, the 'footprint' might be a bit heavy...

You could also just set it up as a centralized web service and allow people on any platform to call it that way. That's what they're for, after all. On Fri, May 9, 2008 at 12:34 PM, D ----- Excess quoted text cut - see Original Post for more -----

Now, back to the issue, I'd like to find out many possible ways/approaches to solve a problem (eliminate the least likely candidates in the first place), then, check out the most promising one(s) ... Thanks.

It sounds like you're asking if you can run a CFML-based function without a CFML engine. The answer is no. You'd need to write it in Java or a .NET language depending on which server platform the system is running. IIS is only a web server. In order to actually execute code, IIS has to be connected to something that can run code (usually a .dll that forwards the request to a runtime environment like J2EE or .NET). Without the CF runtime, none of these servers would know how to execute the compiled classes since CF includes a number of APIs that are used in the compiled Java classes.
