Getting an error in Dynamic Configuration

Question

Hi Guys,
I need to dynamically post the file into different directories based on the file in the source payload.
In Receiver File Communication Channel
Target Directory : *
Filename : *
Checked the ASMA Attributes for filename and directory
Iam refering this weblog
/people/william.li/blog/2006/04/18/dynamic-configuration-of-some-communication-channel-parameters-using-message-mapping
In the mapping
<filename> ---> UDF --> topnode of target message.
My UDF is as below
public String Directory(String a,Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key  = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "Directory");
String FileName = conf.get(key);
FileName = a;
conf.put(key, FileName);
String Directory = conf.get(key1);
Directory = "/SAPInterface/XI/PPD/DHX/out";
conf.put(key1, Directory);
return " ";
But in runtime(moni) iam getting  error as
com.sap.aii.af.ra.ms.api.MessagingException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header
Please suggest me how to correct this.
Thanks

Hi Srinivas,
You said you are having dynamic directories to post the file. But I see you hardcorded or put constant for directory which is /SAPInterface/XI/PPD/DHX/out. I think you need to put //SAPInterface/XI/PPD/DHX/out.
Try this in udf:
public String Directory(String a,Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key  = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "Directory");
String FileName = conf.get(key);
FileName = a;
conf.put(key, FileName);
Directory = "//SAPInterface/XI/PPD/DHX/out";
conf.put(key1, Directory);
return " ";
Put FileName and Directory in file name and directory paramters in receiver communication cahnnel and cehck.
