I  need the sample in Atom, I did not know enough about the difference 
yesterday.

Nevermind. I got it.  First, I did not know enough about http protocol and that 
was part of the problem.  second the documentation in.

http://code.google.com/apis/documents/docs/3.0/developers_guide_protocol.html#Se
archingDocs

can be adapted to google-api-java client by understanding that the POST and 
non-xml lines at the beginning of packets are input information for 
GoogleHeaders.  I am using docs-v3-atom-oauth-sample as reference.

The xml atom information or file's content goes into an InputStreamContent that 
is then given to the request object (request.content).  for example:
//
//all these attributes have their respective variable in GoogleHeaders Object
//the authorization value is filled in existing sample code.
//
POST /feeds/default/private/full HTTP/1.1
Host: docs.google.com
GData-Version: 3.0
Authorization: <your authorization header here>
Content-Length: 73612
Content-Type: multipart/related; boundary=END_OF_PART
Slug: test.doc
//the content from here down can is given using an InputContentStream (refer to 
the only google docs sample to see how it works)
--END_OF_PART
Content-Type: application/atom+xml

<?xml version='1.0' encoding='UTF-8'?>
<entry xmlns="http://www.w3.org/2005/Atom" 
xmlns:docs="http://schemas.google.com/docs/2007">
  <category scheme="http://schemas.google.com/g/2005#kind"
      term="http://schemas.google.com/docs/2007#document"/>
  <title>example document</title>
  <docs:writersCanInvite value="false" />
</entry>

Now, the only question I have is how do you input both Atom-xml information 
(metadata) and document content ( plain text for example) ?  this is not clear 
to me from the existing documentation.

Attached are the two methods to get a text file from docs, and to update the 
plain/text document.  You can add them to docs-v3-atom-oauth-sample.
