Fix for ColdFusion 8 Broken Exception HTTP Response

August 1, 2007 on 3:44 am | In Java, Adobe, ColdFusion |

Here’s a quick and dirty solution for the issue described in: ColdFusion 8 Exception Handling Breaks HTTP Requests.

<cffunction name="onError" access="public" returntype="void" output="false">
 <cfargument name="exception" type="any" required="true">
 <cfargument name="eventname" type="string" required="false">
 
 <cfset var error = getMetaData(exception)>
 <cfset var message = left(reReplace(reReplace(exception.message,"\r|\n"," ","all"),"\s\s+"," ","all"),500)>
 <cfset var msg = "">
 
 <cfloop condition="true">
 <cfif not isDefined("error") or error.getName() eq "coldfusion.runtime.NeoException">
 <cfbreak>
 </cfif>
 <cfset error = error.getSuperClass()>
 </cfloop>
 
 <cfif isDefined("error")>
  <cfset msg = error.getDeclaredField("msg")>
  <cfset msg.setAccessible(true)>
  <cfset msg.set(exception,message)>

  <cfif exception.getClass().getName() eq "coldfusion.runtime.CustomException">
  <cfset msg = getMetaData(exception).getDeclaredField("userMessage")>
  <cfset msg.setAccessible(true)>
  <cfset msg.set(exception,message)>
  </cfif>
 </cfif>
 
 <cfthrow object="#exception#">
</cffunction>

Place that in your Application.cfc and CF won’t break the http requests anymore. Of course this won’t work if you have the Java Access Control enabled in the CF8 Administrator.
