[dspace-tech] Accessibility Checking of Submissions

[George Kozak]

Hello:
I was asked if DSpace is looking into adding accessibility checking to the
content that is submitted into the Repository.  Is this something on the
features to-do list?

Re: [dspace-tech] Error deleting a collection

[Stanislav Orlov]

Hi Claudia,

I ran pg_dump, as you suggested (see attached), and it looks like all the 
three tables (collection2item, community2community, and 
community2collection) have 1 foreign key only each.  For instance, the 
error that I receive complains about comm2coll table not having the 
collection_fk and the old issue mentioned is suggesting to delete this 
foreign key from the table:

"$2" FOREIGN KEY (collection_id) REFERENCES collection(collection_id) 

So, if my table only has the "community_id" foreign key, this old thread 
doesn't seem to apply.  And if the fkey is not present to be deleted, is 
there another way of making DSpace not look for it?

Cheers,
Stan

[dspace-tech] Error Importing Simple Archive Format item with multiple versions

[mmorris]

Hi,

I'm getting this error importing an items with multiple versions using 
DSpace 6.2:

read handle: '20.500.12111/1420.2'
java.lang.NullPointerException

java.lang.NullPointerException

*Steps to reproduce:*

1- export an item with 2 or more versions:
dspace export --type=ITEM --id=20.500.12111/1420 --dest=/tmp/1420 --number=1
dspace export --type=ITEM --id=20.500.12111/1420.2 --dest=/tmp/1420 
--number=2

2- delete the item

3- import the item from the command line.
dspace import -a -e u...@email.com -c 20.500.12111/160 -s /tmp/1420 -m 
1420.map

Things i tried to confirm the initial export was successful:

- If i remove version 2 (folder 2) from /tmp/1420/ i can import the 
original version 20.500.12111/1420 without version 2
- If i change the handle number of version 2 inside the handle file to a 
new handle like 20.500.12111/1500 instead of 120.500.12111/1420.2 i'm able 
to import version 2 as a whole new item but that's not what i'm after. 

It seems like a bug to me, can anyone confirm this?

Regards,
Mike

Re: [dspace-tech] Error deleting a collection

[Claudia Jürgen]

Hello Stanislav,

you most likely did not run into the problem, because you never tried to delete 
anything. There might be issues with collection2item, community2community, too 
if my guess is right that this was this old issue:
http://dspace.2283337.n4.nabble.com/Dspace-tech-running-the-15-to-16-script-td3280357.html

Since  DSpace 5 there is a database command line tool which can
a) info about the db (including missing/faild migration)
b) repair the db (trying to run migrations)

But you are using 4.

I'm no DB expert just know some basic stuff so anybody out there knowing a 
tool/elegant solution?

At the moment you can compare your database with the database schema of DSpace, 
first identifying the discrepancies.
You can generate a description of your db with
pg_dump --schema-only --no-owner Your_Database_Name > YourDatabaseCreation.sql

If it is really only the above mentioned constraints which are screwed up, 
follow the instructions in the thread above, with the usual warning about 
backing up everything properly first.

Hope this helps

Claudia Jürgen

Thank you Claudia,

We started ten years ago and went through a few upgrades. I can see how
this problem might have been created during the process, but we never ran
into the problem until now.  If I look at foreign keys for
community2collection table, I see this:

Name: community2collection_community_id_fkey
Fields: community_id
Referenced Schema: public
Referenced Table: community
Referenced Fields: community_id
On Delete: NO ACTION
On Update: NO ACTION

What do I need to do to fix this?

Re: [dspace-tech] Error to tried to creating a community

[Tim Donohue]

Hi Manuel,

Could you provide us with more information about whether you upgraded or
whether this was a fresh install of DSpace 6.2?  I'd also recommend looking
closely at both your DSpace and Tomcat logs to see if any other errors are
occurring.

The error itself seems very odd, almost like it might be caused by a
configuration problem or Spring initialization error (which is why I'm
wondering if there are other errors in your log files).  It's saying
there's a NullPointerException on this line:
https://github.com/DSpace/DSpace/blob/dspace-6.2/dspace-api/src/main/java/org/dspace/content/CommunityServiceImpl.java#L120

That error doesn't make much sense to me, as that line is simply logging a
new "ADD" event -- and that shouldn't throw a NullPointerException unless
there are other issues, or you've customized the code in some way.

Please send us more information on the dspace-tech list, and hopefully we
can help figure out what is going on.

- Tim

DSpace newer than 1.7 works well for me on Java 8.  I note that Oracle Java 
7 has been EOL for three years.

The error that you quoted is what you get when you run code compiled for 
Java 8 on an older JVM.  It appears that your PostgreSQL driver was 
compiled for Java 8, and JDK 7 won't load it.  You may be able to find a 
version that is compiled with JDK 7 at 
https://jdbc.postgresql.org/download.html

In your position, yes, I would upgrade to Java 8.
