[Dspace-tech] Index-all error

[Mika Stenberg]

Im trying to run index-all on brand new Dspace 1.4.2 installation with
only few test items in it. I get this error when running, what could be
causing it?

Creating browse index
Indexing all Items in DSpace.... ... Done
Creating search index
Exception in thread "main" java.lang.NullPointerException: value cannot
be null
at org.apache.lucene.document.Field.<init>(Field.java:188)

Are you positive this is the 1.4.2 release? Line 890 of DSIndexer in
that release is:

ArrayList fields = new ArrayList();

which will never give you a NullPointerException. Did you upgrade from
an older version, or install it totally "fresh"?

cheers,

Jim

Interestingly I did fresh install with 1.4.2.
I found out that the problem was caused by collections marked as null.

We should deal with this as a bug in DSpace 1.4.2... We can make it
more robust in DSIndexer.

James, this error arises at line 890 of build document, which makes
me think they are still using dspace 1.4.2-beta where that line
corresponds to the getName call on a collection See:

http://fisheye3.cenqua.com/browse/dspace/branches/dspace-1_4_x/dspace/
src/org/dspace/search/DSIndexer.java?r=1797#l890

Thats not the same line in the 1.4.2 release...

http://fisheye3.cenqua.com/browse/dspace/branches/dspace-1_4_x/dspace/
src/org/dspace/search/DSIndexer.java?r=1878#l890

Mika, I see what is happening, Can you make sure you do not have
collections that have no "name"? and we'll throw in some hooks into
the next version of DSIndexer to control for that?

Also beware that you may have dspace 1.4.2 beta installed and on the
official release of dspace 1.4.2
