Auto commit functionality not working correctly in XMLUI
--------------------------------------------------------

                 Key: DS-383
                 URL: http://jira.dspace.org/jira/browse/DS-383
             Project: DSpace 1.x
          Issue Type: Bug
          Components: XMLUI
    Affects Versions: 1.5.2
            Reporter: Robin Taylor


My understanding is that Dspace provides transactional processing by setting 
the database connection to auto-commit=false and doing a 'commit' once all 
processing has completed successfully. However, Manakin has a filter called  
DSpaceCocoonServletFilter which contains the following code that runs after the 
request has been passed on for further processing...

   // Close out the DSpace context no matter what.
        ContextUtil.closeContext(realRequest);

This appears to run, commiting changes to the database, even if an Exception is 
thrown in the main code.

The code needs to be more intelligent and only do a commit to the database 
where appropriate. The current catch-all approach causes problems in the event 
of a failure and also prevents any sort of multiple items upload, eg from a 
reference manager.
