Probably involved with the cocoon upgrades/patching we've been
doing. The ORE is in a Bitstream in the Item right? "cocoon://" not
working for resolving context centric resources was something I
recall breaking and possibly the reason that cocoon "blocks" are
broken in XMLUI, can you give context:// a try and see if that works?
From the cocoon docs...
Define parts inside of an aggregate. You can define as source of a
part a URL. The following list of examples summarizes some useful
part sources:
Use http://foo/bar[1] to merge in xml content via http protocol,
received from machine foo.
Use context://servlet-context-path/foo/bar[2] to merge in xml
content from the servlet context.
Use cocoon:/current-sitmap-pipeline/foo/bar to merge in xml content
from the current sitemap. The appropriate pipeline is selected
matching current-sitemap-pipeline.
Use cocoon://root-sitmap-pipeline/foo/bar[3] to merge in xml content
from the root sitemap. The appropriate pipeline is selected
matching root-sitemap-pipeline.

Hi Scott
Thank you for your answer.
I understood your point and it really wouldn't make sense for me
opening 24 new connections for any new browse collection page. I
tested the same patch I did using "cocoon://" instead of "http://";
and it really works in version 1.6.2 of dspace, as reported by
James Russel, so I think this bug was probably introduced with
changes made after 1.6.2 in the cocoon part of dspace-xmlui,
specially the class BitstreamReader.java that was quite modified
I will probably be experimenting with OAI-ORE in version 1.6.2 but
some one could take a look at this new bug in 1.7.1
Thanks a lot
