Switching web server on ColdFusion

In case there is a need to switch from an external web server to the built-in ColdFusion web server, you can acheive this without reinstalling.

Switch from an external web server to the built-in web server

1. Back up the jrun.xml file.

   This file is in the cf_root\runtime\servers\default\SERVER-INF directory in Windows, and in the cf_root/runtime/servers/default/SERVER-INF directory in UNIX.

2. Open the original jrun.xml file for editing.
3. Locate the WebService service and set the deactivated attribute to false:

   <service class="jrun.servlet.http.WebService" name="WebService">     <attribute name="port">8500</attribute>     <attribute name="interface">*</attribute>     <attribute name="deactivated">false</attribute>     ... </service> 

   
   
4. Locate the ProxyService service and set the deactivated attribute to true:

   <service class="jrun.servlet.jrpp.JRunProxyService" name="ProxyService">   <attribute name="activeHandlerThreads">8</attribute>   <attribute name="minHandlerThreads">1</attribute>   <attribute name="maxHandlerThreads">1000</attribute>   <attribute name="mapCheck">0</attribute>   <attribute name="threadWaitTimeout">20</attribute>   <attribute name="backlog">500</attribute>   <attribute name="deactivated">true</attribute> ... 

   
   
5. Save the file.
6. Copy the CFM pages in your web root directory (including the CFIDE and cfdocs directories) to the ColdFusion cf_root/wwwroot directory, and use appropriate URL references (for example, http://localhost:8500/YourApp1/index.cfm). If you switch from the built-in web server to an external web server, you must copy the contents of the cf_root/wwwroot directory to your web server root. If you are using Adobe Dreamweaver, ensure that you reconfigure any sites that you move from one server to another.
7. Restart ColdFusion.

 

Function ArrayIsDefined() in CF8

This is a new function added in CF8, this function determines whether an array element is defined. This returns true, if the array element is defined (exists); false, otherwise.

Function syntax

ArrayIsDefiend(array, elementIndex)  

Parameters

Parameter	Description
array	Name of a one dimensional array, or the array name and indexes into higher-order dimensions of a multidimensional array.
elementIndex	Index of the element in a one dimensional array, or the index of the element in the final dimension of a multidimensional array.

Usage

To test the existence of an element in a multidimensional array, specify all but the last dimension of the array in the first parameter. For example, the following line tests the existence of element MyArray[2][4][1]:

ArrayIsDefined(MyArray[2][4], 1)  

Example

<h3>ArrayIsDefined Example</h3> <!--- Create a sparse new array. ---> <cfset MyArray = ArrayNew(1)> <!--- Populate an element or two. ---> <cfset MyArray[1] = "Test"> <cfset MyArray[3] = "Other Test">  <cfoutput>     <!--- Display the contents of the array. --->     <p>Your array contents are:     <cfdump var="#MyArray#"></p>          <!--- Check if an existing element is defined. --->     <p>Does element 3 exist?:&nbsp;     #ArrayIsDefined(MyArray, 3)#</p>          <!--- Check if a non-existent element is defined. --->     <p>Does element 2 exist?&nbsp;     #ArrayIsDefined(MyArray, 2)# </cfoutput> 

ColdFusion Security Fix

Adobe has released a security advisory for ColdFusion 7 and 8. This resolves an identified vulnerability that could potentially allow session hijacking for applications utilizing CFID or CFTOKEN. This does not apply to applications using J2EE Session management.
