  1. Adobe ColdFusion Omar Guerra

  2. Overview • This language compares to JavaServer Pages (JSP), ASP.NET, or PHP, and resembles HTML in syntax. • The most distinguishing feature is its associated scripting language, ColdFusion Markup Language (CFML). • ColdFusion supports programming languages other than CFML, such as server-side Action script and embedded scripts that can be written in a JavaScript-like language, known as CFScript.

  3. Overview • ColdFusion is most often used for data-driven web sites or intranets, but can also be used to generate remote services such as SOAP web services or Flash remoting. • It is well suited as the server-side technology to the client-side Flex. • ColdFusion can also handle asynchronous events such as Short Message Service (SMS) and instant messaging via its gateway interface.

  4. Overview • What is ColdFusion capable of? • Query a database • Allow users to upload files • Create/read files on the server (for example, the files that your users upload) • Have a "member's area" (i.e. via a login page) • Have a shopping cart • Present a customized experience (for example, based on users' browsing history) • Create a "member's area" (i.e. via a login page) • Send emails (for example, newsletters to a mailing list) • Schedule tasks to run automatically (for example, your email newsletters) • FTP files to/from another server • Publish web services

  5. Overview (Disclaimer) • Down sides to using ColdFusion • Expensive. • Costs $1,299 full version, $649 upgrade version. • Not as popular as PHP, ASP.NET, or JSP. • Most companies use one of these 3 technologies. • Limited job search. • Primarily used in corporate environment. • Not all web hosting companies support it. • Those that do (www.godaddy.com) charge extra for using it ($1.99 / month).

  6. Main Features • Client and server cache management. • Client-side code generation, especially for form widgets (GUI that displays an information arrangement changeable by the user, such as a window or text box) and validation. • Conversion from HTML to PDF and FlashPaper (virtual printer ; all files printed from FlashPaper become Flash or PDF files). • Data retrieval from common enterprise systems such as Active Directory, POP, HTTP, FTP, Microsoft Exchange Server. • Platform-independent database querying via Open Database Connectivity (ODBC) or Java Database Connectivity (JDBC). • XML parsing, querying, and validation.

  7. Other Programming Languages • ColdFusion and Java • ColdFusion can be deployed to servlet containers such as Apache Tomcat and Mortbay Jetty. • ColdFusion is a Java EE application • Enterprise Edition: builds on the solid foundation of Java Platform, Standard Edition (Java SE) and is the industry standard for implementing enterprise-class service-oriented architecture (SOA) and next-generation web applications. • Its code can be mixed with Java classes to create a variety of applications and utilize existing Java libraries. • It has access to all underlying Java classes, supports JSP custom tag libraries, and can access JSP functions after retrieving the JSP page context.

  8. Other Programming Languages • ColdFusion and .NET • ColdFusion 8 natively supports .NET within the CFML syntax. • Developers can simply call any .NET assembly (partially compiled code library for use in deployment, versioning and security) without needing to recompile or alter the assemblies in any way. • Data types are automatically translated between ColdFusion and .NET. • Offers ability to access .NET assemblies remotely through proxy which allows users to leverage .NET without having to be installed on a Windows operating system.

  9. Installation • Before installing, it is a good idea to shut down your firewall. Some firewalls may cause installation errors. • Step 1: After confirming the language on first screen, the ColdFusion installation process begins.

  10. Installation • Step 2: Confirm the license agreement:

  11. Installation • Step 3: Select the installation type. • If you have a purchased copy, then enter the serial number at this screen. • In most cases, selecting “Developer Edition” is fine.

  12. Installation • Step 4: Installer Configuration • The first option (“Server Configuration”) is the most common option.

  13. Installation • Step 5: Subcomponent Installation • Select the subcomponents you want to install. By default, all subcomponents are selected.

  14. Installation • Step 6: Select Installation Directory • Select the directory you would like to install into. It is recommended to leave this as default.

  15. Installation • Step 7: License Agreement • This screen only appears if you previously selected Adobe LifeCycle Data Services ES (at step 5):

  16. Installation • Step 8: Adobe LifeCycle Data Services ES Installation • If you have a serial number for Adobe LifeCycle Data Services ES, enter it here. Otherwise leave it blank:

  17. Installation • Step 9:Previous ColdFusion Installation Detected • If you do, you can choose to have both versions co-exist on your computer, or to overwrite the previous version.

  18. Installation • Step 10: Configure Web Servers/Websites • If you run your own web server (such as IIS or Apache), this screen allows you to select which websites should be configured to use ColdFusion. Click on “All IIS websites”:

  19. Installation • Step 11: Choose ColdFusion Administrator Location • This screen lets you choose where to put the files for the ColdFusion Administrator. The CF Administrator is usually accessed at http://localhost/cfide/administrator

  20. Installation • Step 12: Administrator Password • You are required to enter a password for accessing the CF Administrator.

  21. Installation • Step 13: Enable RDS • As a general rule, disable RDS on production servers. Only enable RDS if you need to access the server remotely for development purposes. In this demonstration, it is important to ENABLE RDS:

  22. Installation • Pre-Installation Summary • Review your settings. If all is correct, click “Install”:

  23. Installation • Step 15: • Once it has been installed, a notification window tells you installation was completed successfully. If not, you will be notified of any errors that occurred during installation:

  24. Tag Syntax • ColdFusion Syntax refers to a set of rules that determine how the ColdFusion application will be written and interpreted by the CF Server. • These rules are referred to as the ColdFusion Markup Language (CFML). • CFML consists of a number of tags. • Similar to HTML, these usually consist of an opening tag and a closing tag, and are surrounded by greater than (>) and less than (<) symbols .

  25. Tag Syntax • ColdFusion tags use the following format: <tagname attribute=“value”> Code/text that is affected by the surrounding tags. </tagname> Code Example: <cfoutput query=“myQuery”> #firstname#<br /> </cfoutput>
