Set up a default "Accept" header or a more comprehensive error message when
"accept" is not set
-----------------------------------------------------------------------------------------------
Key: STANBOL-369
URL: https://issues.apache.org/jira/browse/STANBOL-369
Project: Stanbol
Issue Type: Improvement
Reporter: Florent ANDRE
In documentation, many curl examples doesn't indicate accept header.
When this header is not set some "strange" error messages appear, that are
really not clear for newcomers.
== Examples of error messages ==
=== From curl ===
