XML-RPC Return Hash

[BlackMage]

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?
