Hi Eugeni,

I just added this item: http://demo.dspace.org/xmlui/handle/10673/32
to the demo site of DSpace and this breaks the XMLUI and will break OAI as soon as it is re indexed.

So I think our problems might be unrelated but there is a DSpace bug regarding characters that are disallowed in XML 1.0.

Regards
Christian

To close the problem I should say that there is no real issue with the non-ASCII characters and OAI.

But in XOAI there is conversion between String and byte array using the platform's default charset. Which is not always UTF-8. One can fix this starting Java/Tomcat with
  -Dfile.encoding=UTF8

One more thing I noticed now is that in some logs in dspace.log the non-ASCII characters are replaced by ??
To get the real non-ASCII characters one can add in log4j.properties
  log4j.appender.A1.encoding=UTF-8

    I have a freshly installed DSpace 6.2 with 15 items in it.
    I have not changed anything in the OAI configuration.
    Two of the items have READ access for certain groups only. The
    rest are accessible to everybody.

    Problem 1.
    When I run
    dspace oai import -c

    I get in dspace.log two exceptions (I suppose for each of the
    restricted access items):

    2017-10-19 17:55:22,650 WARN  org.dspace.xoai.util.ItemUtils @
    Authorization denied for action READ on
    BITSTREAM:3d21ebf7-ef3e-4d98-a265-c4a516b1740b by user null

    action READ on BITSTREAM:3d21ebf7-ef3e-4d98-a265-c4a516b1740b by
    user null

    The whole text of the exception is very long.

    Problem 2.
    After that I am trying
    http://localhost:8080/oai/request?verb=Identify
    <http://localhost:8080/oai/request?verb=Identify>
    http://localhost:8080/oai/request?verb=ListSets
    <http://localhost:8080/oai/request?verb=ListSets>
    http://localhost:8080/oai/request?verb=ListMetadataFormats
    <http://localhost:8080/oai/request?verb=ListMetadataFormats>
    http://localhost:8080/oai/request?verb=ListIdentifiers&metadataPrefix=xoai
    <http://localhost:8080/oai/request?verb=ListIdentifiers&metadataPrefix=xoai>
    and it all works.

    But for
    
http://localhost:8080/oai/request?verb=GetRecord&identifier=oai:localhost:nls/3&metadataPrefix=xoai
    
<http://localhost:8080/oai/request?verb=GetRecord&identifier=oai:localhost:nls/3&metadataPrefix=xoai>
    (nls/3 is an item accessible to everybody)
    I get in the browser

    java.io.IOException:
    com.lyncode.xoai.dataprovider.exceptions.WritingXmlException:
    Error trying to output ''
       
    
org.dspace.xoai.services.impl.cache.DSpaceXOAICacheService.store(DSpaceXOAICacheService.java:113)

    The whole text of the exception is very long.

    My question is - am I missing something in the configuration or is
    this a known problem with DSpace 6.2?
