OAI Error
Cameron, Jacob
Hi All,
DSpace 6, Windows Server2008 RC2, Tomcat and Postgres.
When I try to access any of our OAI records, we get a huge error stack. I’m not sure where to begin to look to resolve this. If you start at http://www.uleth.ca/oai/request?verb=ListSets and click on Records, it gives the following error.
HTTP Status 500 - com.lyncode.xoai.dataprovider.exceptions.WritingXmlException: Error trying to output ''
type Exception report

Figured it out. I typo’ed searching through here the first time.
If you add -Dfile.encoding=UTF-8 to the Java OPTS in the config tomcat app, it will resolve the issue.
