Hi,
I've made an installation of Fedora 3.4.1. And I've run into weird
problem with REST API access.
I got this error when invoking:
http://<myserver>/fedora/objects/city%3Alocations/datastreams/LIST/content
However, if I invoke troublesome link (see log file below) I see correct
data in the web browser.
I mean 'curl -g
"http://<myserver>/fedora/get/city:locations/city:Collection/list"' gets
me desired data.
Moreover, when I invoke this via Java API all works just fine.
Where did I go wrong?
I would like to have access for all objects only for specified
user/password.
In the fedora.log @ DEBUG level I have this error log:
DEBUG 2011-09-07 13:32:09.412 [http-8081-1]
(DefaultExternalContentManager) in getExternalContent(),
