For those to whom it might be useful, here is the wrapper cfc I used for
java.io.FileWriter which, in the application I was concerned with, attained a
10x performance improvement over <cffile action='append'...> under condition
that over 20,000 lines needed to be written out to a text file.
It aint nuthin special, but might save someone a few minutes...
<cfcomponent displayname="javaFile" output="true">
<cffunction name="initFile" returntype="boolean" access="remote"
output="Yes">
<cfargument name="filename" type="string" required="yes">
<cfset var retValue=false>
<cfif not(fileexists(arguments.filename))>
<cffile action="write" file="#arguments.filename#"
output="">
</cfif>
<cfset this.FileObject = createobject("java",
"java.io.FileWriter").init(arguments.filename, true)>
<cfset retValue=true>
<cfreturn retValue>
</cffunction>
<cffunction name="appendRaw" returntype="boolean" access="remote"
output="yes">
<cfargument name="fileData" type="string" required="yes">
<cfset var retValue=false>
<cfset this.FileObject.write(arguments.fileData,0,
len(arguments.fileData))>
<cfset retValue=true>
<cfreturn retValue>
</cffunction>
<cffunction name="appendLine" returntype="boolean" access="remote"
output="yes">
<cfargument name="fileData" type="string" required="yes">
<cfset var retValue=false>
<cfset var CrLf = chr(13) & chr(10)>
<cfset var opbuffer=arguments.filedata & CrLf>
<cfset this.FileObject.write(opbuffer,0,len(opbuffer))>
<cfset retValue=true>
<cfreturn retValue>
</cffunction>
<cffunction name="done" returntype="void" access="remote" output="yes">
<cfset this.FileObject.flush()>
<cfset this.FileObject.close()>
<cfreturn>
</cffunction>
</cfcomponent>
