BlueDragon 7.1: Deploying CFML on ASP.NET and the Microsoft .NET Framework 19

4.2.3 DSN-Less Connections

ColdFusion 5 had added support for a new DBTYPE=”dynamic” option on CFQUERY and related

database processing tags. CFMX removed support for that feature, as did the Java editions of

BlueDragon. But the .NET edition of BlueDragon now supports this feature. For more informa-

tion, see the discussion of CFQUERY in the BlueDragon 7.1 CFML Enhancements Guide.

4.2.4 ASP.NET Connection Strings

BlueDragon.NET also supports the use of ASP.NET connection strings in place of BlueDragon

datasources. When rendering a CFQUERY tag—or any other tag that specifies a DATASOURCE

attribute—BlueDragon 7.1 will first look for a configured datasource of the specified name. If a

BlueDragon datasource of the specified name is not found, BlueDragon will then look for an

ASP.NET connection string of that name.

This feature allows ASP.NET connections strings and associated ADO.NET connection pools to

be shared across ASP.NET and CFML pages.

4.3 CFML Web Services Served as .NET Web Services

When a CFML web services are exposed on BlueDragon for the Microsoft .NET Framework, it

may be important to know that they are created as pure .NET web services. BlueDragon has been

certified as .NET Connected because of this feature.

Besides affording the strength and reliability of Microsoft’s implementation of web services

(compared to the open source Axis-based web services implementation in CFMX and the Java

editions of BlueDragon), another benefit is that when CFML web services are browsed in the

.NET edition of BlueDragon, their metadata display is provided by the normal .NET interface

typically shown for ASP.NET web services (pages served using the .asmx extension).

In other words, if a CFC method is enabled to permit access to it via web services (using the

Access=”remote” attribute of CFFUNCTION), you can request display of that CFC’s methods

as a web service in the browser, such as:

http://localhost/somedir/somecfc.cfc

This will display an HTML-based interface showing its available method(s) along with links to

enable invocation of the method, just as would be made available to those who attempt to browse

an ASP.NET web service (a file with an asmx extension).
