How do you create a Java array of bytes using CF?

[Enayet Rasul]

I'm helping a co-worker on this one. She needs to create an array of
bytes for some application she's using (the sample app was done in
VB). Below is the sample VB code:

Dim key() As Byte = {&H30, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0,
&H0, &H0, &H0, &H0, &H0, &H0, &H3, &H30, &H0, &H0, &H0, &H0, &H0, &H0,
&H0}

Is there a way to create an array of bytes in Java? I got as far as
writing this code..but I failed miserably in adding an element.

<cfobject action="create" type="java" class="java.util.Vector"
name="JavaArray" />
<cfobject action="create" type="java" class="java.lang.Byte" name="JavaByte" />

<cfset temp = JavaByte.init('H30')>
<cfset temp = JavaArray.addElement(JavaByte)>

I realize ColdFusion and Java does some different data type
conversions to each other...but I don't know if this is out-of-scope
for CF to do.

You could always write a java class and then call that from CF.
