Hi Uttam, This error sounds like it is related to the configuration of DSpace 6.x, since it seems to come from the new Apache Commons Configuration settings.
https://wiki.duraspace.org/display/DSDOC6x/Configuration+Reference#ConfigurationReference-ConfigurationFileSyntax Have you checked that your configuration files for any preceding or trailing spaces (as described earlier in this thread)? Did you upgrade from DSpace 5 and perhaps forget to update the configuration of DSpace (the configuration system changed between DSpace 5 and 6, see: https://wiki.duraspace.org/display/DSDOC6x/Upgrading+DSpace#UpgradingDSpace-ReleaseNotes/SignificantChanges You could also either diffing your configs against the out-of-the-box configurations to see if that shows any obvious misconfigurations. Or you could temporarily revert to the out-of-the-box configurations to see if that resolves the issue, and then slowly update it to your existing configuration. Essentially, this sounds like a configuration issue in one of your *.cfg files. Unfortunately the Apache Commons Configuration system doesn't seem to return a very useful error message here, so I cannot say for certain which file or configuration is the problem. Good luck, and please let us know on this mailing list if you discover the issue. We haven't been able to reproduce this problem yet, so if you find a way to do so, we can add it to our documentation, etc. - Tim On Thu, Oct 19, 2017 at 6:11 AM uttam dhakal <udedha...@gmail.com> wrote: > Hello, > > I have got the exact same problem, did you find the solution to your > problem? > > Thank you > > On Wednesday, January 18, 2017 at 7:02:42 PM UTC+1, m.ne...@icm.edu.pl > wrote: >> >> Thanks, but that is probably not mine case.
