RE: Run a class file generated with CF outside of CF
Hey Nathan,
So what I was doing was this. I am working on a new web app written with
extJS. I have a CFC that I call that builds the client side app. It reads
all of the ux and util directories and generates a config file used by
jsBuilder to compress, combine and minify the JS used on the client side as
well as compress and move CSS and resources.
I am working towards getting a CI server setup and also need to ensure all
developers can run a build locally. That's where the problem arises. The
developers (JS developers) will not have CF installed on their local machine
(or our pre-configured EC2 instance), and so I need to move the process of
generating the jsBuilder config and executing it out of CF and into
something that can run on any developers workstation - without a big install
and setup.
Since its just 1 CFC, I thought I could just use the java classes. But of
course there are dependencies.
I found a wicked, super cool solution to this last night! I downloaded Ralio
Express and was able to get it to execute my CFC with basically zero setup.
Ralio Express is freakin awesome! There's no installer, you just run
start.bat to start the server and stop.bat to stop it. So I've added it to
my SVN and written an ANT task that starts it up and then runs the CFC that
indexes all the directories, read in an XML config file and calls (via
cfexcecute) the CFC that handles the build.
My ANT task has these targets:
target name=startRalio description=Starting Ralio Server
depends=MakeDirectories
java jar=tools/build/ralio/lib/start.jar
dir=tools/build/ralio/
fork=true
spawn=true
maxmemory=512M
arg value=-h/
arg value=-DSTOP.PORT=8887/
arg value=-DSTOP.KEY=railo/
/java
!-- wait for server to start up --
waitfor maxwait=10 maxwaitunit=second
and
socket server=localhost port=/
http url=http://localhost:/index.cfm/
/and
/waitfor
/target
target name=doBuild description=Call the Ralio script to in turn
call JsBuilder and do compilation depends=startRalio
get src=http://localhost:/build/doBuild.cfm;
dest=buildresult.txt /
!-- look for buildresult.txt, read the result and throw an
error if any errors exist --
loadfile property=buildresult
srcFile=${desktop.build.dir}buildresult.html/
echo message=${buildresult}/
antcall target=checkResult /
antcall target=stopRalio /
/target
Never used Ralio before, but very impressed with it!

Yeah, it's probably not going to happen. I mean, I am getting famous for
saying that it's software, so we can do anything, but the problem is the
amount of work it takes to do a thing. In this case you have to load a good
amount of the CF server into memory, all the other related classes (one
..class for the cfc, one for each cffunction, etc.), then fake a request
response object, or whatever servlets do (I knew at one point). Your best
bet is to not do this.
It would be much easier to call your CF server rather than try to use the
generated code out of context. There are many ways to call into CF from
Java. The easiest one would be to hit it via a HTTP URI. Second easiest
would be a web service. Third, you can use the CF services gateway - you can
set up a local socket listener, which should be really performant. Also, I
think Terrence Ryan had a project on RIAForge that lets you call it via the
command line console.
I wonder, what is the underlying reason for wanting to call the generated
classes? Sort of an odd request. Why are you doing this? Maybe there's a
better way to accomplish your end goal.

I assume this is not at all possible since the classes include lots of
CF specific classes for various functions. Is that right? Is this not
possible?

Re: Run a class file generated with CF outside of CF
Brook,
Great solution. Kind of complicated but totally doable.
I won't pretend to understand the complexity of the cfc you have, but all
that overhead to run one cfc seems extreme. I have a couple suggestions.
1- use native Ant to do it all. You can concat files and run jsmin or yui
compressor straight from ant. I was experimenting with this most of
yesterday with some pretty good success and can share it if you are
interested.
2- use scripting from within ant. You can include the Rhino js.jar scripting
engine, or groovy, or any number of JSR-223 compatible scripting languages
and get access to Ant's methods like making a fileset from within
javascript, as well as all the underlying java libraries. This works really
well because you can still use a cool programming language and keep it all
within Ant, no railo or cfml dependencies required.
Anyways, just some ideas, and like I said, I can share some of that with
you. I plan on talking about this stuff a little bit from my CF Unconference
talk at MAX this October, so if you're in the neighborhood...

Re: Run a class file generated with CF outside of CF
FWIW, Railo 4.0 will make this even easier by allowing CFML to be executed directly from the command line (or ant) without needing a server running at all. This will effectively make CFML a general purpose scripting language that can be used outside the servlet container! Builds of 4.0 are currently pre-alpha and undergoing testing in-house. Once Railo 3.3 goes gold (should happen around the end of this month), that will become the stable release and 4.0 will appear on the development builds / bleeding edge provider.

RE: Run a class file generated with CF outside of CF
Sean, Re: Railo from the command line That's sounds very cool and will be very useful. Nathan, Yeah, I know its kinda nuts to do all that just to run one CFC. But it is a pretty big CFC and it does a lot including reading in and parsing XML config files that are used by the application, and indexing directories etc. While I would agree it would be better to keep it all inside ANT without the dependency on Railo (thank Peter!), the main factor for me was implementation time. I'm already behind schedule and no time to re-write this code - so using Railo was the fastest solution. It has the added benefit that it is leveraging some existing CFML and plus, CFML scripting is where I am strongest (that and JS..), so it made sense. I think if I had the time I would have done it all in ANT. What you said about using Rhino sounds very promising.
