Problem Disseminating DSpace SITE

[Saad Itani]

Dears we recently updated DSPACE from 5.x to 6.4 and the site is up and running smoothly, however I am stuck in a problem regarding export of AIP.

Info:

DSpace version:  6.4

If I run this command, I get the following error:

/data/bin/dspace packager -d -a -t AIP -e dsp...@xx.com -i 10938/0 dspace-aip.zip

Warning at xsl:stylesheet on line 14 column 35
  Unrecognized version 1.1: treated as 1.0

This may take a while, please check your logs for ongoing status while we process each package.

===========================================

thank you!

[Saad Itani]

[UPDATE]

Changing the type to METS example /data/bin/dspace packager -d -a -t METS -e dspace@xx   -i 10938/0 /data/BACKUP/aip-backup/dspace-aip.zip

worked!

any idea why AIP is not working?

[Tim Donohue]

Hi,

Based on the initial error "stacktrace" it looks like the error begins here:
https://github.com/DSpace/DSpace/blob/dspace-6.4/dspace-api/src/main/java/org/dspace/content/packager/PackageUtils.java#L822

The error results in a NullPointerException which seems to imply that the "groupName" it encounters is either empty string or null (missing).  

Maybe somehow your database has a Group that has *no name*?  That shouldn't be possible in DSpace, but it almost sounds like what has occurred here.

To see if you have a nameless Group, you'd want to look in your "epersongroup" database table to see if there's an entry in there with a null or empty "name" column.  If you find one, you can give it a name (even just call it "unnamed" or something) and try the export again.

If you have other questions, let us know on this list.

Tim

Dear Tim,

Thank you for reaching me in the support of the problem, will check and report back if we have a Null eperson group table.

Regards,

Saad

Hi Saad,

maybe you got unfinished registrations. We did run into a similar
problem when we tried a complete AIP type AIP In/Export (in 5.x) just
fort testing it.

You can check this with a database query:
select * from eperson where password is null;

You can choose not to export passwords with the option -o passwords=false

Hope this helps

Claudia

Hello Tim,

I would like to thank you for your support as it worked after I added a value into a Null field under the epersongroup name table.

Thank you so much, Problem solved!

Regards,

Saad
