cfimport
231
Usage
The following example imports the tags from the directory myCustomTags:
<cfimport
prefix="mytags"
taglib="myCustomTags">
You can import multiple tag libraries using one prefix. If there are duplicate tags in a library, the
first one takes precedence.
JSP tags have fixed attributes; however, if the tag supports runtime attribute expressions, most tag
libraries support the use of the syntax
#expressions#
.
To reference a JSP tag in a CFML page, use the syntax
<prefix:tagname>
. Set the prefix value in
the
prefix
attribute.
To use JSP custom tags in a ColdFusion page:
1.
Put a JSP tag library JAR file (for example, myjsptags.jar) into the ColdFusion server directory
wwwroot/WEB-INF/lib. If the tag library has a separate TLD file, put it in the same directory
as the JAR file.
2.
At the top of a CFML page, insert code such as the following:
<cfimport
prefix="mytags"
taglib="/WEB-INF/lib/myjsptags.jar">
To reference a JSP tag from a JAR file, use the following syntax:
<cfoutput>
<mytags:helloTag message="#mymessage#" />
<cfoutput>
The
cfimport
tag must be on the page that uses the imported tags. For example, if you use a
cfimport
tag on a page that you include with the
cfinclude
call, you cannot use the imported
tags on the page that has the
cfinclude
tag. Similarly, if you have a
cfimport
tag on your
Application.cfm page, the imported tags are available on the Application.cfm page only, not on
the other pages in the application. ColdFusion does not throw an error in these situations, but the
imported tags do not run.
You cannot use the
cfimport
tag to suppress output from a tag library.
For more information, see the Java Server Page 1.1 specification.
Example
<h3>cfimport example</h3>
<p>This example uses the random JSP tag library that is available from the
Jakarta Taglibs project, at http://jakarta.apache.org/taglibs/
<cfimport taglib="/WEB-INF/lib/taglibs-random.jar" prefix="randomnum">
<randomnum:number id="randPass" range="000000-999999" algorithm="SHA1PRNG"
provider="SUN" />
<cfset myPassword = randPass.random>
<cfoutput>
Your password is #myPassword#<br>
</cfoutput>
