Name

GetPageContext

Synopsis

Acts as a wrapper for the Java PageContext object. This function returns an object containing the attributes, methods, and other configuration information available to the current page. Using this object, it is possible to look up various information concerning the current page, such as scope and variable values. This function can also be useful for integrating ColdFusion with J2EE applications as it provides access to request and response objects. Additionally, include and forward methods are exposed, making it possible to communicate with JSP pages using the equivalent of jsp:forward and jsp:include. To see the contents of the object for the current page, simply dump it using the cfdump tag:

<cfdump var="#GetPageContext( )#">

Method objects can be viewed by dumping them as well:

<cfdump var="#GetPageContext( ).getRequest( )">

This retrieves the server name from the getRequest method:

<cfdump var="#GetPageContext( ).getRequest( ).getServerName( )#">

The following example includes a JSP page named hello.jsp in your ColdFusion page while passing it a URL parameter:

<cfoutput>
#GetPageContext( ).include("hello.jsp?name=Joe")#<br>
</cfoutput>
