CF Summit 2017 – Part 2

Starting from Part 1 of my “CF Summit 2017” series I will dive into some of my conversations with Adobe and more “Application Monitoring Suite” details.

The Adobe Team

20171117_101210Let me start out by saying that I know a number of people, myself included, enjoyed having the ColdFusion engineering team on-site at the conference. I want to thank them for the long trip from India which appears to be at least a 24 hour trip one-way. I could barely stand the 3 hour cattle flight from Omaha on Southwest. Those seats were great when I was a kid half my current size – but they never seemed to take into account that American adults actually sit in those seats too!

I spent a bit of time speaking with Anit Kumar, the Technical Support Manager, who was very welcoming of what I had to say. A number of people also wanted his attention, so I also spoke a bit to Vamseekkrishna Nanneboina, the Quality Engineering Manager. Continue reading

CF Summit 2017 – Part 1

My co-worker at CF Webtools, Wil Genovese, and myself were fortunate to attend the Adobe ColdFusion 2017 Summit this year.

The primary focus of the event was on “Aether”, the next version of ColdFusion, which will be known as “ColdFusion 2018”. The primary topic surrounding Aether was the API Manager, Containerization (Docker), security by default and a new “Application Performance Monitoring Suite”.

Running ColdFusion 9 on Windows 10

CommandBoxLogoMost of us find it impossible to install and run Adobe ColdFusion (ACF) 9 on Windows 10. There are a select few that suspiciously find it easy to install and run on Windows 10.

One of the more popular methods is to create a Windows 7 Virtual Machine (VM) and install Windows 7 there. I’ve even done that. But what you find, particularly on Hyper-V, is that it lacks portability. I can’t reasonably send another developer my VM. #1 due to licensing issues #2 it can be huge depending upon the size you reserved for the virtual drive.

But thanks to the Ortus team, and with a little open mindness, CommandBox takes care of this issue. From the Ortus website: “CommandBox is a standalone, native tool for Windows, Mac, and Linux that will provide you with a Command Line Interface (CLI) for developer productivity, tool interaction, package management, embedded CFML server, application scaffolding, and some sweet ASCII art. It seamlessly integrates to work with any of our *Box products but it is also open for extensibility for any ColdFusion (CFML) project as it is also written in ColdFusion (CFML) using our concepts of CommandBox Commands. It tightly integrates with our contribution community; ForgeBox, so developers can share modules world-wide.”

So basically what’s going on here, in this blog entry’s context, is CommandBox will run ACF 9+, Railo 4.2 and Lucee 4.5+. This is done by running a WAR in Java against CommandBox’s own web server which still supports ACF9 integration. Technically you’re supposed install Java 1.7 for official support of ColdFusion 9. However, from what I’ve seen, it runs just fine on Java 1.8.

Here are the easy steps in Windows to get you running in less than 10 minutes:

  1. Download CommandBox at https://www.ortussolutions.com/products/commandbox#download. I suggest “With JRE Included”.
  2. Extract the contents to something like C:\CommandBox. For all other OS’s see Installation.
  3. Open a Command Prompt
  4. Go to your new directory, such as “CD C:\CommandBox”
  5. Type “box” and enter
  6. This will then initiate Box for the first time and then take you to the Box CLI.
  7. Change the directory to your first website that needs ColdFusion 9, in this example. ex: “cd \websites\cf9test”
  8. Here we will set the ColdFusion engine, version, hostname (optional) and name (optional). Run:
    server set app.cfengine=adobe@9 (this will run the latest version of ACF 9)
    server set web.host=cf9test.local (be sure to set in DNS or your hosts file to 127.0.0.1 or you will get a “Cannot assign requested address: JVM_Bind” error)
    server set name=cf9
    *
  9. Step #8 will be saved in server.json and never needs to be done again as long as that file is intact. For more configuration arguments, see Server.json.
  10. Type “start” and enter**
  11. This will download the ColdFusion 9 WAR and extract it and then initialize it. This may take a number of minutes.
  12. Once CF9 is “installed” a browser window will open up to “http://cf9test.local” or whatever you set the web.host to. If you didn’t define web.host it will open up to “http://127.0.0.1”. Either way it will use a random port number. This port number can be defined in the server.json configuration file.
  13. Append “/CFIDE/Administrator” to the URL it is using. If you accidentally closed the browser tab, look for the blue CF task icon in your task bar. Click it once and click “open browser”.
  14. The password to the ACF admin is “commandbox”
  15. Configure necessary settings such as data sources or enable J2EE session variables if needed.
  16. Then go back to your root URL and you should be up and running.

There is so much you can do with CommandBox, including https, URL rewrite and even generating CFM frameworks. See the CommandBox Manual for more.

*When setting the server name, this will allow you to keep configurations stored such a DSN in the admin. You can use a general name such as “cf9” and use it among different instances or you can use a more specific name just for that instance or a group of instances such as “mysite”. Without it, you have a chance of loosing or overwriting configurations in the CF Admin.

There is a way to script out you ColdFusion config, such as DSN’s, using CFConfig CLI. However as of this post writing, it doesn’t allow you to use ColdFusion 9. But feel free to experiment using this with other versions or later down the road.

There are a number of other ways to configure your servers as well. See Configuring your CommandBox servers on first start by Brad Wood.

**The trick to thinking here is the webroot for the website being loaded up in your browser, is the directory you run “start” in.

ColdFusion Framework Note

I tend to monitor the “ColdFusion Programmers” Facebook group. Today a poster asked:

Hi guys, What do you prefer: CFWheels or Coldbox? I used before CFWheels and is good but I recently starts playing with Coldbox and so far is pretty cool – Jorge Alexandro Martinez Dominguez

My response was:

I use FW/1 for about everything because it’s simple and what I know. However ColdBox will give you a ton more functionality via modules and they aggressively keep that framework up-to-date. They are very involved in the community and even have a “Into The Box” event once a year for pre-conference. I would use either, but if you’re new to both I’d probably look at ColdBox. Both base frameworks are similar.

ColdBoxLogo2015_300Brad Wood, from Ortus Solutions, also chimed in a with a blog post from 2015 about how ColdBox 4 changed pretty drastically. It’s always a good read when asking yourself the Framework question: It’s Time You Looked At ColdBox 4

Simple jQuery AJAX w/ ColdFusion

I had a request to supply a sample HTML page that would send a subscriber’s email address to ColdFusion without reloading the page. So I figured I’d post it here for any others looking for a simple example. This method uses jQuery, AJAX and a ColdFusion component.

index.html or index.cfm

<!DOCTYPE html>
<html>
	<head>
	</head>
	<body>
		<div id="subscribeContainer">
			<input type="email"><button type="button">Subscribe</button>
		</div>
		<script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>

		<script>
			(function($) {
				// bind the button with an event handler
				$('#subscribeContainer button').click( function(e) {
					// when button is pushed, POST data to remote ColdFusion component method
					$.post(
						'subscription.cfc',
						{
							method: 'subscribe',
							email: $('#subscribeContainer input').val()
						}
						)
						.done( function() {
							// everything worked
							$('#subscribeContainer').text('You have been subscribed.');
						})
						.fail( function() {
							// something failed
							$('
<span>There was an error subscribing.</span>').appendTo('#subscribeContainer');
						}
					);
				});
			})(jQuery);
		</script>
	</body>
</html>

subscription.cfc

component {

	remote void function subscribe( required string email ) {
		// call database insert method here
	}

}

Come Work With My Team!

CF Webtools LogoCF Webtools, where I’ve placed my career coming up on 8 years, is seeking a talented ColdFusion developer. We’re 25 strong and are looking for #26!

You can either work remotely in the comforts of your own personal office space (AKA your spare bedroom) or enjoy your own office space at our Omaha, NE office. We keep in touch with each other day-to-day via Skype. This provides us with one-on-one, project chats and company-wide chats. Most of the time it’s text chatting, but we also use it for voice when it’s just more efficient.

CF Webtools is a great fit for me because it provides the diversity and challenges needed not to become worn out with the same task over-and-over. There are always new opportunities that arise over the years. With this also comes constant learning. Each project brings its own set of challenges.

Granted most projects are not picture perfect as they tend to build up technical debt over time; but you get the opportunity to sell your expertise to the customer giving them the best path forward fitting their needs.

Experience needed not only includes ColdFusion but SQL, SQL, SQL, web server, Windows, Linux, Mobile OS, basic networking and just a good set of troubleshooting skills.

Give Mark or Jason a call at 402-408-3733, tweet @cfwebtools or contact the business owner Mark via his blog at coldfusionmuse.com .
