XML-RPC Java/Perl Problem, Help Please?

I am having problem with a Java program that calls a Perl/CGI Script, creates a hash and returns. A simple example looks like this:

Perl Script:
------------------------------------------------------------------------------------

sub createHash{

%hashTable = ();

$hashTable{first} = 1; # inserts a new hash table entry with key=first and value=1
$hashTable{second} = 2; # new entry with key=second and value=2

return %hashTable;

}#end createHash

Java Program
------------------------------------------------------------------------------------

public void getHash(){

HashMap hashmap=new HashMap();
Vector params = new Vector();

//Create Variables
try {
XmlRpcClient xmlrpc = new XmlRpcClient(SERVER_URL);

//Set Strings
String methodName = MyProgram.createHash;

System.out.println(xmlrpc.execute( methodName, params));
//The line below is commented out because it throws an error
//hashmap=(HashMap) xmlrpc.execute( methodName, params);

} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlRpcException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}//end class

The problems are this, when, I System.out.print the return hash created in Perl, is only prints out the last value. When I cast the return value to a Java Hash, it throws a string execption.

So how do I return a hash table or multiple values from a perl program?
