easy, and you’ll nd instructions on the installation in the ColdFusion 8 manual, Installing

and Using ColdFusion, in the chapter “Installing Integrated Technologies”, available online

http://livedocs.adobe.com/coldfusion/8/htmldocs/othertechnologies_11.html

The next step is to enable debugging in the ColdFusion Administrator (separate from

the traditional debugging), as well as to set the port on which the debugger will listen,

and also to enable ColdFusion RDS (Remote Development Services). See “Setting

up ColdFusion to Use the Debugger” in the chapter of the ColdFusion Developer’s

Guide entitled “Using the ColdFusion Debugger”. There you will also see discussion

of a minor dierence in setup for ColdFusion’s multiple instance (Multiserver) or J2EE

congurations versus the standalone Server conguration. This chapter can be found at

http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=usingdebugger_1.html

Finally, you’ll need to congure Eclipse itself in a couple of ways, which are also

discussed in that documentation chapter. This involves conguring a connection to

your server via RDS in the ColdFusion 8 Eclipse plugins interface, conguring mappings

if ColdFusion and Eclipse are not on the same machine, and switching to the Eclipse

Debug perspective. While FusionDebug does not rely on the ColdFusion RDS feature,

the CF8 debugger does. All these steps are described in the docs mentioned above, as

well as at the top of another page in that chapter, “Using the ColdFusion Debugger”, at

http://livedocs.adobe.com/coldfusion/8/htmldocs/usingdebugger_6.html

Besides the Adobe documentation, there’s a very nice Adobe Dev Center article by Brian

Szoszorek, “Using the ColdFusion 8 Step-Through Debugger for Eclipse”, which walks carefully

through the conguration and setup of the Admin and the debugger, with ample screenshots.

It’s available online at

http://www.adobe.com/devnet/coldfusion/articles/debugger.html

I presume you’ll read those resources for setting up ColdFusion and the debugger, but I do

address some aspects of these conguration features later in the article.

First Stop: Setting a Breakpoint

Now that you’ve congured both the debugger and ColdFusion itself, and you’ve started

the debugger (as described in the docs mentioned above), open the le you wish to debug

in the Eclipse environment. You can begin by telling the tool that you want to stop execution

on a given line of CFML code. This is called setting a breakpoint. You just right-click on the

line of code in the Eclipse editor, and choose Toggle Breakpoint. Where in FusionDebug you

could right-click anywhere on the line, in the CF8 debugger, you must be sure to place the

mouse over the line number (if shown) or over the area just to the left of that (the grey area

on the left in Figure 1 below). You can also use the shortcut, Ctrl-Shift-B.

When the CFML template you’re working with is requested, and that line of code would be

executed, the program halts and the debugger interface reects that execution has halted.

It will open the le if it’s not already open, and show the line of code on which execution

has stopped. (See Figure 1)

The blue dot to the left of the line shows where a breakpoint has been set, and the blue arrow

and shading on the line indicates that control has halted on that line. Those familiar with

FusionDebug will notice that this part of the interface is the same. In fact, both debuggers

are really leveraging underlying features of the Eclipse interface and its built-in debugging

functionality. Still, without the CF8 debugger or FusionDebug, it wouldn’t be possible to

debug CFML requests using Eclipse alone.
