When possible, ColdFusion automatically handles the conversion of types between it and Java. Most types (for example, integer, date, and boolean) have obvious conversions. Complex data types (including structure and query) do not have exact Java equivalents and are converted to Map. (Applies to:...
When Java objects are invoked, ColdFusion attempts to locate the required objects automatically. ColdFusion searches the following locations (in this order): WEB-INF/lib, WEB-INF/classes, the classpath specified in the ColdFusion Administrator, the default JVM classpath. (Applies to: ColdFusion MX)
Any Java classes placed in the WEB-INF/classes directory will be automatically loaded by ColdFusion. (Applies to: ColdFusion MX)
Any Java libraries (.jar files) placed in the WEB-INF/lib directory will be automatically loaded by ColdFusion. (Applies to: ColdFusion MX)
If you make multiple requests to a Web Service you can improve performance by not making ColdFusion set up and prepare the connection repeatedly. How? Instead of using use CreateObject(), this way ColdFusion maintains Web Service information in a variable that can be used repeatedly. And you can...
If you need to share session data across a cluster then you must use CLIENT variables. Right? Wrong! CLIENT variables can indeed be shared, but if you are using ColdFusion for J2EE (and J2EE managed SESSION variables) then SESSION variables can be clustered too. There is one gotcha however,...
ColdFusion MX for J2EE does not have a checkbox for enabling white space suppression. This is an oversight, the option is actually supported, it is just not exposed in the Administrator. The solution? Edit the configuration file directly. Here's what you need to do: 1) Stop ColdFusion. 2) Open the...
Web Services are invoked using . Right? Not necessarily. ColdFusion MX will actually allow you to invoke Web Services using CreateObject() using the syntax CreateObject("webservice", "wsdl") (replacing "wsdl" with the wsdl URL). CreateObject() returns and object allowing you to invoke methods using...
If you are using / the order of the blocks does not matter - ColdFusion will find the best fit. This is unlike earlier versions of ColdFusion where "any" had to be the last block (or it would catch all errors). (Applies to: ColdFusion MX)
If you are using then you should never have code that is in the block but not in a or . ColdFusion 5 allowed this (mistakenly) and ColdFusion MX no longer permits this (although you should never have been doing it anyway). (Applies to: ColdFusion MX)
