Getting Started With The ColdFusion 8 Debugger

After a 7 year hiatus, ColdFusion once again has an interactive debugger, and this time it is built on top of Eclipse

Ben Forta's Blog

After a 7 year hiatus, ColdFusion once again has an interactive debugger, and this time it is built on top of Eclipse (and uses the same debugging interface as Flex Builder, and other Eclipse plug-ins). If you are interested in taking the debugger for a spin, here's what you need to know to get started:

First of all, you need ColdFusion 8. If you don't have it yet, get it!

You'll also need the ColdFusion 8 Eclipse extensions, and these must be installed (here is some installation help).

Before you can use the interactive debugger you need to enable debugging support in ColdFusion. Here's what you need to do:

  1. Open the ColdFusion Administrator.
  2. Select "Debugger Settings" in the "Debugging & Logging" section.
  3. Check "Allow Line Debugging".
  4. The debugger needs a port to communicate over, if you can't use the default change it (just be sure to use an unused port, and you can't use the port that ColdFusion itself is on).
  5. By default ColdFusion allows up to 5 concurrent debugging sessions, you can raise or lower this value as needed.
  6. Click "Submit Changes", and restart ColdFusion is you are instructed to do so.

Once you enable line debugging it will remain enabled even if ColdFusion is restarted. As a rule, do not enable line debugging on production servers, and you may want to always leave it enabled on development boxes.

Now that debugging is enabled, you need to configure Eclipse to tell it what ColdFusion server to debug against. Servers need to only be defined once, and once defined you may debug against them as needed. You can define as many servers as you need, local and remote, as long as the server has RDS enabled (and you have an RDS login).

The first thing you need to do in Eclipse is define the RDS settings for your ColdFusion server. These settings are used by the debugger, as well as the wizards, RDS panels, and more. To define your RDS connection do the following:

  1. In Eclipse, select Window->Preferences to display the Preferences dialog.
  2. Select ColdFusion in the tree, expand the selection, and select RDS Configuration.
  3. Click New to add a new server, or just select any server to edit it.
  4. Provide a description, host name, port, and login details, and then save. To use your local ColdFusion server specify 127.0.0.1 as the Host Name, 8500 as the Port (if using the integrated HTTP server), leave the Context Root blank, and provide the login information.
  5. Click "Test Connection" to make sure the RDS connection is working, and the click OK.

Once the RDS connection is defined you'll be able to browse data sources in the RDS Dataview tab, view available CFCs in the Services Browser tab, use the wizards, and more. And you'll be able to debug applications, but first ...

Now that your RDS connection is defined, you need to define the ColdFusion servers you wish to debug against. Here is what you need to do:

  1. Locate the Debug button in the toolbar, it's the one with the little green bug on it.
  2. Don't click the button, instead, click the down arrow to the right of it and select "Debug ..." to display the Debug dialog which is used to manage debugging configurations.
  3. The Eclipse debugger is used to debug all sorts of applications created in all sorts of languages, and along the left of the dialog you'll see a list of applications types that can be debugged. Select "ColdFusion Application".
  4. You'll see any defined ColdFusion debugging servers under the "ColdFusion Application" branch. To add a ColdFusion server click the New button (the leftmost one above the list) while you have "ColdFusion Application" selected.
  5. Name this server, and then select the RDS server to use from the drop down list.
  6. If you are debugging against a local server (running on the same machine as Eclipse) you can ignore the mappings section. If ColdFusion is on a remote server then you'll need to define mappings here.
  7. Click "Apply" to save your changes.

Again, servers need to be defined once, and they'll be saved for future use.

To debug your code you can do the following:

  1. Open the ColdFusion file to be debugged in Eclipse.
  2. Set breakpoints as needed by double clicking to the left of the desired line in the vertical bar to the left of the Eclipse editor window. You'll see a little circle appear indicating that a breakpoint has been set. You can also right click in the vertical bar and select "Toggle Breakpoint".
  3. Now you need to switch to the Eclipse Debug view (called a "Perspective" in Eclipsese). If you see a Debug button listed with the Perspectives on the top right of Eclipse, click it. Or, just click the Open Perspective button (or select Windows->Open Perspective) and select "Debug".
  4. Once you are in the Debug perspective start the debugging session. To do this, go back to the dialog where you defined the ColdFusion server (under the Debug button), select the ColdFusion server to debug against, and click the Debug button at the bottom of the dialog.
  5. Eclipse will pause while it opens a debug session, connecting to the specified ColdFusion server. You'll see the connection show up in the Debug window.
  6. Now just open any browser and run your application. When you request a page with a breakpoint, execution will pause, and the debugger will pop up. You'll be able to step through code, view variables and expressions (in the top right panel), see generated server output, and more.
  7. When you are done debugging, you can terminate the debug session by clicking the red square Terminate button.

And that'll do it. I know this seems complex and a lot of work, but the bulk of it is initial setup. Once that setup is complete you'll be able to quickly and easily fire up the debugger on demand and when needed.

In a prior life he was a ColdFusion customer (he wrote one of the first large high visibility web sites using the product) and was so impressed he ended up working for the company that created it (Allaire). Ben is also the author of books on ColdFusion, SQL, Windows 2000, JSP, WAP, Regular Expressions, and more. Before joining Adobe (well, Allaire actually, and then Macromedia and Allaire merged, and then Adobe bought Macromedia) he helped found a company called Car.com which provides automotive services (buy a car, sell a car, etc) over the Web. Car.com (including Stoneage) is one of the largest automotive web sites out there, was written entirely in ColdFusion, and is now owned by Auto-By-Tel.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
