You cannot sort an array that is returned by a java object. CF errors out. You will have to create a new array and loop-and-append to it then sort your array. Like so

<cfset timezoneClass = createObject( "java", "java.util.TimeZone" ) />

<cfset timezoneIDs = timezoneClass.getAvailableIDs()>

<!--- THIS FAILS --->

<cfset arraysort(timezones,"textnocase")>

<!--- THIS SUCCEEDS --->

<cfset timezones = arraynew(1)>

<cfloop array="#timezoneIDs#" index="tzid" >

          <cfset arrayappend(timezones,tzid)>

</cfloop>

<cfset arraysort(timezones,"textnocase")>

Curious.  In your first example, you set timezoneClass and timezoneIDs, but then try to sort timezones (which, AFAICS, you didn't set.)

Should have been

<cfset timezoneClass = createObject( "java", "java.util.TimeZone" ) />

<cfset timezoneIDs = timezoneClass.getAvailableIDs()>

<!--- THIS FAILS --->

<cfset arraysort(timezoneIDs,"textnocase")>

<!--- THIS SUCCEEDS --->

<cfset timezones = arraynew(1)>

<cfloop array="#timezoneIDs#" index="tzid" >

          <cfset arrayappend(timezones,tzid)>

</cfloop>

<cfset arraysort(timezones,"textnocase")>

Coldfusion arrays are not Java arrays, but Vector Lists: http://www.bennadel.com/blog/1030-Building-Java-Arrays-In-ColdFusion-Using-Reflection.htm

If you want to sort a Java array, use array.sort(): http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Arrays.html
