This approach extracts the document name from a custom, user-defined feature
structure that cTAKES defines. This is not part of core UIMA.
So I don't think this will work unless you're running the cTAKES pipeline.
-------------
UIMA doesn't know about documents as a built-in concept. If you want, you can
have your Collection Reader or other code which sets up the CAS with the
original document, add a special feature structure (which you define) with any
information you need about the document you use to initialize a CAS. Because
this user-defined feature structure is put into the CAS, you can extract it
later in any Annotator.
The examples that come with UIMA include a collection reader:
org.apache.uima.examples.cpe.FileSystemCollectionReader. This example creates a
user-defined feature structure called SourceDocumentInformation to hold the path
to the source file.
You can see this example in
http://uima.apache.org/d/uimaj-2.4.0/tutorials_and_users_guides.html,
search for sourcedocument.

In my CAS Consumer I use:
void processView(JCas view) throws Exception {
String docName = DocumentIDAnnotationUtil.getDocumentID(view);

DocumentIDAnnotationUtil is a cTAKES class available here:

Not sure if that's the best way, but hope it helps.

Subject: how to get the original filename of the input document?
Hello
I did my first aggregate AE with several Annotators. All works fine but,
now, I
need the original filename (or filepath) of the input Document. I did
several
tries with getSofaDataURI() = but it is null, and other Annotations in the
JCas
but without success. While I can with success obtain mime-type, language,
etc...
I did a xml serialization of the JCas and I can see the filepath in a
<string>...document.txt</string> tag. How can I access it?
many thanks
Michelangelo
