We all know how important Internet based applications have

become and how enterprises are taking to them in a big way. One way of creating

these applications is using ColdFusion language, and with the latest version,

developers can use the ColdFusion Builder IDE that is filled with all  resources

for quick development of these applications. In this article we use this IDE to

create a simple application.

Implementing ColdFusion9



You can download ColdFusion9 and ColdFusion Builder from http://tinyurl.com/5njlm3.

The installation of ColdFusion builder is straight forward and there are just

two modes of installation. If you are already using Eclipse IDE, the software

can add a plug-in to it, or one can have a stand alone application of ColdFusion

Builder. For this article we have used ColdFusion Builder as a stand alone

application.

The installation of ColdFusion 9 on the other hand,

requires several user inputs. First the user needs to define 'Install Type'

which is the 'Developer Edition' in our case. Then he has to define 'Installer

Configuration' that defines the type of server where ColdFusion applications

would run. In this sample implementation we have installed ColdFusion 9 as a

self contained server running single instance with an embedded JEE server. In

the next step, the user can define websites or servers that would work with

ColdFusion. The final steps require the user to define the administrator

password for ColdFusion Administrator and RDS. Here RDS stands for remote

desktop service that enables developers to connect remotely to server for

development purposes.

Now that we have all the tools for writing a ColdFusion

application, let's start by building a sample application. First open ColdFusion

Builder, alternately, if you are using Eclipse select ColdFusion perspective.

The next step is to define connection to a ColdFusion Server. For this, click on

the 'Server' tab at the bottom. Then click on Add Server button that is shown by

a server and '+' sign. This action would pop up 'Add Server' window. Here one

needs to select 'ColdFusion' as server type. The next window would prompt a user

to enter server settings. Here, enter a unique 'Server Name' so that you can

remember it from the server list. The next important configuration to be entered

is 'Host Name' which is the IP address of the server ('localhost' in our case).

In 'Other Settings' enter 8500 as 'WebServer Port' and the RDS user name and

password defined during installation. In Local Server Settings enter 'Server

Home' and 'Document Root' and click on Finish. Now as we are using local

machines the settings in our case would be 'C:\ColdFusion9' and

'C:\ColdFusion9\workout' respectively. You would be able to see the defined

server in the server list at bottom. One can right click on this server to

change settings and state.

This is the interface of ColdFusion Builder. At the bottom

we can see a list of servers while on the left we can see created projects.

Click on File>New>ColdFusion Project and give a name to

your project ('ColdfusionSample'). We need to store this project at the web root

of ColdFusion Server. Create a new folder in root and add this path in 'Project

Location' field and click on Next. In this window, one needs to define the

server, select created server ('localhost') from drop down list box and click

Finish. In this implementation, we would create two pages, the first one would

be used to enter user names while the second would display the name along with a

message. To accomplish this, create two ColdFusion pages by right clicking

project in left window and clicking on 'New>ColdFusion Page'. Name these pages

as 'TestOne.cfm' and 'TestTwo.cfm'. Now add the following code to TestOne.cfm:

The Server configuration settings window pops up when you

click on the server sign at the bottom of Builder window.

These windows show the created page. Enter your name in the
left window and hit 'Submit'. This would display the newly created welcome

message, shown in the right window.

This is a simple code that creates a text box and button.

The most important tag in this code is

. This tells the server to send the

information contained by the form to a desired page mentioned in 'action,

attribute. Now add the following code to 'TestTwo.cfm':

In the above code outputs data from a source to

the screen. There are several other similar tags that can be used for different

actions, like etc. Below the editor window one can see installed

browsers. Click on a browser window to check output of created pages. It is very

simple to write a ColdFusion base application and it resembles a lot with HTML

which we all know very well. The usage of builder only further simplifies code

development.
