Container container = null;
SimpleDateFormat simpledatFormat = new SimpleDateFormat("yyyyMMdd");
Date date = new Date();
String datewithYear = simpledatFormat.format(date);
SimpleDateFormat simpledatFormat1 = new SimpleDateFormat("HHmmss");
Date date1 = new Date();
String datewithMs = simpledatFormat1.format(date1);


 DynamicConfiguration conf = ((DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION));

DynamicConfigurationKey key = DynamicConfigurationKey.create("http:/"+"/"+"sap.com"+"/"+"xi"+"/"+"XI"+"/"+"System"+"/"+"File" , "FileName");

String oldFileName=conf.get(key);
String valueNew;

if( oldFileName == null){

 valueNew = "HRXML"+datewithYear+datewithMs+".xml";
}
else{
valueNew =oldFileName+datewithYear+datewithMs+".xml";
}
//set the new filename
conf.put(key, valueNew);

remove the line

Container container = null;

should solve your problem.

Container container = null;

..

..
DynamicConfiguration conf = ((DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION));

bound to get a NPE as your variable container is not getting intialized to a valid object ref here...
