TMCH Domain Create Extension Fails

[rajasweb]

Following code, causes registry to reject the command

DomainCreateCommand command = new DomainCreateCommand(domainName, username, pass, contacts);

DomainCreateResponse response = new DomainCreateResponse();

byte[] base64EncodedPart = TmchXmlParser.extractBase64EncodedPartFromSmdFile(
            new FileInputStream(pathToSMD));

TmchDomainCreateCommandExtension extension = new TmchDomainCreateCommandExtension();
extension.setEncodedSignedMarkData(new String(base64EncodedPart));
command.appendExtension(extension);

logger.info(command.toXML());
sessionManager.execute(new Transaction(command, response));

return response;

This returns following XML as response:

<?xml version='1.0' encoding='UTF-8'?><epp xmlns="urn:ietf:params:xml:ns:epp-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0 epp-1.0.xsd">

Which registry are we talking about?
