Passing parameters to Java JT400 object

I need to pass a byte array as my input and an int as the output length for the Class ProgramCall.

My error is   

parameterList[0] (null): Parameter value is not valid.

My thoughts are

I think (but I'm not completely sure) I'm having trouble because I'm passing a Coldfusion Array where a Java Array is needed to pass the arguments.

Coldfusion arrays start at index 1 and Java Arrays start at index 0.

(1) Am I correct in what I believe is causing my error?

(2) How can I convert the Coldfusion Array to a Java Array?

Here is the documentation for Java JT400 object Class ProgramCall

http://publib.boulder.ibm.com/iseries/v5r1/ic2924/info/rzahh/javadoc/com/ibm/as400/access/ProgramCall.html

Here is my code

<!--- I am the system object --->

<cfobject
        action="create"
        type="java"
        class="com.ibm.as400.access.AS400"
        name="mysystem">

<!--- I am the program call object ---> 

<cfobject
        action="create"
        type="java"
        class="com.ibm.as400.access.ProgramCall"
        name="myprogram">

<!--- I am the program parameter object ---> 

<cfobject
        action="create"
        type="java"
        class="com.ibm.as400.access.ProgramParameter"
        name="myparameter">

<!--- I am the as400 text object ---> 

<cfobject
        action="create"
        type="java"
        class="com.ibm.as400.access.AS400Text"
        name="mytext">
                         
<!--- Initialize our system object --->

<cfset mysystem.init(AS400system,Trim(UCase(loginname)),Left(Trim(loginpass),10)) />

<!--- Execute our AS400 username validation --->

<cfset mysystem.ValidateSignon() />

<!--- Initialize our as400 text object and convert string to a byte array --->

<cfset mytext.init(5) />
<cfset nametext = mytext.toBytes("hello") />

<!--- Initalize our program parameter object --->

<cfset myparameter.init(2) />

<!--- Set input data and output data length using the Class methods of ProgramParameter --->

<cfset myparameter.setInputData(nametext) />
<cfset myparameter.setOutputDataLength(20) />

<!--- Set parameters to a Coldfusion Array --->

<cfset parameterlist = ArrayNew(1) />
<cfset parameterlist[1] = myparameter.getInputData() />
<cfset parameterlist[2] = myparameter.getOutputDataLength() />

<!--- Initalize our program object and run our program --->

<cfset myprogram.init(iseries,ProgramtoRun, parameterlist) />
<cfset myprogram.run() />
