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.Mark On May 12, 2011, at 11:13 AM, [email protected] wrote: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 modifiedI will probably be experimenting with OAI-ORE in version 1.6.2 but some one could take a look at this new bug in 1.7.1Thanks a lot Paulo Jobim ----- Mensagem de [email protected] --------- Data: Wed, 11 May 2011 10:57:30 -0500 De: Scott Phillips <[email protected]> Endereço para Resposta (Reply-To): [email protected] Assunto: Re: [Dspace-devel] OAI-ORE Harvesting & BITSTREAMSPara: "[email protected]" <[email protected]>Cc: [email protected] > This will require some more time to look at it.
