Breaking up a byte array into smaller chunks in ColdFusion using Java

bytes.cfm

<cfset text = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.

<!--- Get the byteArray of the text to be handled --->
<cfset byteArray = text.getBytes() />

<!--- An array to store the broken up chunks --->
<cfset bytes = [] />

<!--- THe java array utility --->
<cfset javaArray = createObject("java", "java.util.Arrays") />

<!--- The number of bytes for each chunk --->
<cfset numberOfBytes = 117 />

<!--- loop over the byte array --->
<cfloop from="0" to="#arrayLen(byteArray)#" index="byteIndex" step="#numberOfBytes#">
  <!--- Check to see how many bytes are left --->
  <cfif byteIndex+numberofBytes GT arrayLen(byteArray)>
    <cfset numberOfbytes = arrayLen(byteArray) - byteIndex />
  </cfif>

  <!--- Get the next N Bytes --->
  <cfset arrayAppend(bytes, javaArray.copyOfRange(byteArray, byteIndex, byteIndex+numberOfBytes)) />

  <!--- Output the size of the last byteArray Added --->
  <cfoutput>
    ArrayLen: #arrayLen(bytes[arrayLen(bytes)])#<br />
  </cfoutput>
</cfloop>

<!--- Output the array of byteArrays --->
<cfdump var="#bytes#" />
