Description
Gets
the current ColdFusion PageContext object that provides access to
page attributes and configuration, request, and response objects.
Usage
The ColdFusion
PageContext class is a wrapper class for the Java PageContext object
that can resolve scopes and perform case-insensitive variable lookups.
The
PageContext object exposes fields and methods that can be useful
in J2EE integration. It includes the include and forward methods
that provide the equivalent of the corresponding standard JSP tags.
You use these methods to call JSP pages and servlets. For example,
you use the following code in CFScript to include the JSP page hello.jsp
and pass it a name parameter:
GetPageContext().include("hello.jsp?name=Bobby"); ===
When
you use GetPageContext to include a JSP page in
a CFML page on WebLogic, you may need to flush the output of the
CFML page with cfflush before calling the JSP page.
Otherwise, the ColdFusion output appears after the JSP output.
The
methods supported on the returned PageContext are only the ones mandated
by the JSP specification. To look up scopes by name, use the StructGet function,
for example:
<cfset myscope = "server">
<cfset myserver = StructGet(myscope)>
For
more information, see your Java Server Pages (JSP) documentation.
On
WebLogic, you may need to flush the output of the CFML page (using
cfflush) before calling a JSP page. If you do not, the ColdFusion
output appears after the JSP output.
On JBOSS, if you use
this function and you include any JSP file, the content of the JSP
file is processed prior to the processing of any CFML tags before
the function.
Example
<!--- This example shows using the page context to set a page
variable and access the language of the current locale. --->
<cfset pc = GetPageContext()>
<cfset pc.setAttribute("name","John Doe")>
<cfoutput>name: #variables.name#<br></cfoutput>
<cfoutput>Language of the current locale is
#pc.getRequest().getLocale().getDisplayLanguage()#</cfoutput>.
