Anyone seen the ColdFusion Coding Guideline that Adobe had on their site? It seems to have disappeared and I don't have a copy.
here it is on the 'wayback machine' web archive

Guys I almost spent a day on googling to find step by step tutorial for writing my first RESTFul service. No Luck
My environment is as follow
JDK 1.7
JBoss 713
Maven
Eclipse Indigo
Any pointer will be helpful. Thanks
Thank you. Though "RESTFul Java with JAX-RS" is quite old and lot of things evolved current past, gives good insight on the concepts. As Surya explained you need to go though multiple resources to get a good understanding on REST. What's the best source for learning how to create RESTful APIs in Java?
DropWizard provides end-end easy solution to write and deploy REST Services. Really impressive.
I'm a django developer but I want to continue learning other things, now asynchronous development.
I have been reading about node.js, I understood that it can be used with django and exists frameworks like express.js, so I don't know what to learn. Besides I read a bit about tornado because I'm better with python than javascript.
What do you advise me? tornado or node.js? another else? if node.js, should I learn it with django or it is better alone?
Which is more popular and has more libraries/documentations/jobs ?
Thanks in advance.
Tornado it's a good choice but I do not like the doc another one is Twisted this one has a good documentation I like so much.
I'm also a Django developer and I like so much Node.js this one has a big community a lot of documentation also has a very cool librarie for WebSockets socket.io about express It's the backend of MySpace but I do not like so much express.
Combine Django and Node.js It's not so hard but it's a quite dangerous. I did a demo of how to combine them here you have the github
I have to create web application similar to twitter with a few tweaks using django. I am clueless if I have to use a CMS for this or any other existing django-application. Working from ground up is quite tedious to be honest. Can anyone recommend me which CMS( or anything else) I should attempt trying?
There is a project called trillr1. According to its page:
"Trillr is a Twitter-like microblogging service enhanced with user directory and group discussion features. " that's maybe what you want.
https://contributions.coremedia.com/trillr1
I guess, the closest you can come with an out-of-the-box software to imitate Twitter is Status.net, the software, that powers identi.ca. However, this is a PHP application.
I'm not aware of something similar in the Django world.
Just downloaded Coldfusion 9 developer for review purposes. I am at the administrator page 127.0.0.1:8300 and I think everything has worked fine. I want to do a simple "Hello World" example. One tutorial gave me a simple 6 line script to do this and it looks pretty simple and understandable. I went to notepad and created the following:
<html>
<head><title>Hello World</title></head>
<body>
<cfoutput>#ucase("hello world")#</cfoutput>
</body>
</html>
It told me to save it as helloworld.cfm in inetpub/wwwroot directory. I could not find such a directory on my system. So I saved it to C:\helloworld.cfm. Then it told me to go to my browser and type http://localhost/helloworld.cfm. I got something to the effect of a page not found error. Any help you can spare here.
Secondly, and more importantly, exactly where do I really need to be to be to create and run the above helloworld.cfm script above? Is there another tool I must have to create the above script to do this? I also understand that there is very little tutorial documentation on Coldfusion 9, why is that the case. Can you offer me any suggestions. I would really like to use this development tool. Adobe says it is the easiest development tool out there. You will have a tough time convincing me of that at this stage, however, I just might be missing a procedural/processing step thats real simple. I hope this is the case. Thanks for you valuable time.
When you installed ColdFusion did you hook it up to a webserver or did you install it in standalone mode?
Did you install it as standard ColdFusion or Multiserver?
The reason I ask is that depending on how you installed it will determine where you will find the web root.
For example, ColdFusion standard in stand alone mode will have the web root under something like C:\ColdFusion9\wwwroot
Multiserver standalone will be something like C:\Jrun4\servers\cfusion\cfusion-ear\cfusion-war\
Installation with a connection to a web server will have asked you where you server's web root is and so on
To create scripts; notepad, but there are two eclipse based IDEs you might like to try. CFEclipse is free and ColdFusion Builder is adode's commercial product.
First of all, Welcome to the ColdFusion community!
I believe Jerry has done a default ColdFusion install. The CFAdmin URL as mentioned is 8300, so i guess it is a multi server installation.
As pointed out by stephen, your web root would be something like \Jrun4\servers\cfusion\cfusion-ear\cfusion-war\
You need to place your helloworld.cfm in the above path.
I recommend ColdFusion builder/ CFEclipse to start with.
CF is a easy language, you will realize that soon :)
http://localhost/ will point to where your web server is configured. So obvious question is did you configure a web server such as IIS or Apache? Which OS are you using and which install of ColdFusion did you pick (standard, multiserver, other...)?
If you don't want to use an external web server you can use the built-in one, I have never really used it much but here is a link that should get you going: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=webservmgmt_3.html
To create CFM files you can use pretty much any editor, the most popular one is Eclipse (http://www.eclipse.org/) coupled with the CFEclipse plugin (http://www.cfeclipse.org/). Adobe now has a IDE based on Eclipse called CFBuilder (http://www.adobe.com/products/coldfusion/cfbuilder/features/) which is gaining speed quickly, but it is not free.
I am new to ColdFusion and ColdBox (and programming). I tried to setup ColdBox but some of the links in the sample applications are broken.
My configuration is a GlassFish v3 installation with the current Railo OSS. I access my site through Apache 2.2.14.
So instead of http://127.0.0.1:8080/railo/ I access my environment trough http://railo/.
In Railo I have a webroot mapping / to C:/webapps/myproject/.
I have copied the current ColdBox 3M4 to C:/webapps/myproject/coldbox. I can access the dashboard through http://railo/coldbox/dashboard/index.cfm and have access to all options.
My problems start the moment I try to open the sample gallery:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented
it from fulfilling this request.
exception
java.io.FileNotFoundException: C:\webapps\viss-dev\coldbox\samples
(Zugriff verweigert)
note The full stack traces of the exception and its root causes are
available in the GlassFish v3 logs.
GlassFish v3
OK, no problem, just enter the link directly: http://railo/coldbox/samples/index.cfm.
The site looks plain, who cares - BUT all local links look like this: http://127.0.0.1:8080/coldbox/samples/applications/helloworld/index.cfm (railo is replaced with 127.0.0.1:8080).
Looks like trouble. To make my confusion perfect: when I try to access the login app: http://railo/coldbox/samples/applications/sampleloginapp/index.cfm and hit the submit button, I am redirected to this address: http://railo/railo/coldbox/samples/applications/sampleloginapp/index.cfm.
I believe that this is not really ColdBox-related, but it manifests itself when I try to use ColdBox, so here I am.
P.S.: amazon.de takes too long to ship the ColdBox book :(
Here's a suggestion, The good people at Vivotech have developed a couple of different installers for both Windows/IIS7 and various flavours of Linux for both Railo and Open BlueDragon. The setup installs Tomcat, Railo/Open Blue Dragon and the necessary connectors to the web server. Here's the link: http://www.viviotech.net/company/installers.cfm
I think you'll find using the installers to be a lot easier than working through it yourself. If you want to go that route, Adobe and various bloggers have instructions on how to do it. Matt Woodward has a very good blog posting on it: see MattWoodward.com, He also has a presentation on this, you can see it here.
hth,

Since you are new to ColdFusion (and programming in general), I would recommend developing against Adobe ColdFusion. The Developer Edition of ColdFusion is free and available from Adobe.com. You won't need to mess around or configure GlassFish since Adobe ColdFusion comes with a baked-in pre-configured Tomcat, providing both servlet engine and web server.
Just install the 'Stand-alone' version of ColdFusion Developer Edition, copy the ColdBox files into the webroot and in less than 15 minutes you be up and running.
You should also check out ColdFusion Builder which is currently available in beta from http://labs.adobe.com. It has full language support and integrated help content for learning the ins-outs of the language.
As far as the ColdBox book goes, it's available as an eBook if you really can't wait. ;-)
DISCLAIMER: I spend about 50% of my waking life devoted to making ColdFusion better as the CF Product Manager at Adobe. :-)
i have given up on glassfish and i am now struggling with tomcat :D
