Overview
• Overview of generic problem
• Detailed View of ColdFusion
• Applications of ColdFusion on Co-Op
• Future developments analysis
What people want when developing a web app
• Browser Independence
• Ease of programming
• Scalability in application functionality
• Rapid development of application time
• One consistent look and feel of programming structures
What is ColdFusion?
• ColdFusion is a complete Web application development platform—a programming language, an application server, a development environment, and a framework for delivering enterprise services. But it is also a straightforward technology for adding basic Web database functionality to your Web site.
Code Example<!--index.cfm-->
<cfinclude template=“app_locals.cfm”>
<cfswitch expression=“#attributes.fuseaction#”>
<cfcase value=“main”> <cfinclude template=“qry_GetShoppingCart.cfm”> <cfset UserShoppingCart=session.UserShoppingCart> <cflocation url=“index.cfm?fuseaction=Catalog”> </cfcase>
<cfcase value=“addItem”> <cfinclude template=“act_AddItem.cfm”> <cflocation url=“index.cfm?fuseaction=cartSummary”> </cfcase>
<cfcase value=“ClearCart”> <cfinclude template=“act_ClearCart.cfm”> <cflocation=“index.cfm?fuseaction=Catalogue”> </cfcase>
</cfswitch>
Reasons why it is commercially accepted
• Simplicity - easy to learn
• Power – over 70 tags available in language
• Community – large open source community of developers
• Software Maturity – was originally created in the late 80’s

Introduction of JWISConcept of Operations (CONOPS)
JWIS will automate weather support to the mission planning and execution process through an interactive, dynamic web-based interface that supports operational and tactical level planning/decision making, mission rehearsal and training. JWIS will take the first steps towards automatically integrating weather forecast and impact databases into AF mission planning systems.
Deficiencies of ColdFusion
• Macromedia is the only vendor that dictates ColdFusion code structures
• Rapidly losing market share to Java Server Pages
• Much smaller toolkit than JAVA– Not as many options available
Macromedia’s Solution
• ColdFusion Version 5.0 will incorporate a JAVA taglet library
• Will incorporate two different scripting languages and application frameworks that run in the same environment
Reasoning Behind Solution
• Merges two popular design paradigms
• Provides a niche for Macromedia to be involved in the emerging adoptability JAVA
What Servlets Have to Offer
• JAVA equivalent to Active Server Pages
• Platform Independent
• Easy for any JAVA class to be instantiated into JSP code
• Can include any future JAVA capabilities
ColdFusion 5.0
• JAVA developers can now change classes without having to restart ColdFusion each time
• Incorporation of JAVA specific tags
• Incorporation of JRun’s JAVA server into ColdFusion
