Required metadata field 'dc.title' doesn't exist

[David Brian Holt]

I just installed Dspace 6 and I'm getting this error message when I launch a webapp.  I emailed helix84 off-list (sorry about that!) and he responded that it is a database problem.

He said that:

"Both error messages indicate some unexpected problem with the database.

> java.lang.NullPointerException

https://github.com/DSpace/DSpace/blob/dspace-6.0/dspace-api/src/main/java/org/dspace/core/AbstractHibernateDAO.java#L48

> java.lang.IllegalArgumentException: Required metadata field 'dc.title' doesn't exist!

> at org.dspace.content.CommunityServiceImpl.findAllTop(CommunityServiceImpl.java:166)

https://github.com/DSpace/DSpace/tree/dspace-6.0/dspace-api/src/main/java/org/dspace/content/CommunityServiceImpl.java#L166"

I ran both 

/dspace/bin/dspace database test

/dspace/bin/dspace database info

and it didn't display any errors.

BTW, I couldn't get Dspace to work at all with Tomcat7 or Tomcat8.  I eventually tried Jetty9 and that worked.

Any ideas?

BTW, I noticed that the java process is running under the user "jetty".  Is that right?  If not, how do I fix that?

Thanks,

I figured out how to edit the jetty startup script to run as the "dspace" user.  That didn't fix my issue.

BTW, this is the error I get when I try to create an administrator.  The database seems to be working correctly.

Any suggestions would be greatly appreciated.  :)
