Help Returning a Hash

I am having a problem with a Java program that calls a Perl/CGI Script using XML-RPC, creates a hash and returns it. 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 is this, when I perform a 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 this means the return value is considered a string and not a hash map or a hash table.

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