Peter-Paul,
I guess in your Schema you have MCCI_MT000100HT02.Message specified as a
type, then an element of that type as the root element of document
instances. The problem is that you are parsing the file using the
MCCIMT000100HT02Message.Factory, and not the
MCCIMT000100HT02MessageDocument.Factory. The xxxDocument is the instance
of the document.
Try the following:
String file = "D:/Htb/Dev/message/EE07_xmlbean.xml";
File inputFile = new File(file);
try
{
MCCIMT000100HT02MessageDocument message =
MCCIMT000100HT02Message.Factory.parse(inputFile);
String ext = message.getMCCIMT000100HT02Message().getId().getExtension();
System.out.println(ext);
...
This should do what you were expecting.
