Hi all,

We have been running Dspace for some years now and now are trying to upgrade to 
1.5.2 and at the same time move from Postgresql to Oracle. I'm looking at the 
batch import whether that would be an option to migrate data from Postgresql to 
Oracle. As I do not have access to the server, I've installed Dspace 1.5.2 on 
my Windows XP machine, using Postgresql as database. On the dspace 1.4.2 
postgresql server I used the batch export to export collection item. On dspace 
1.4.2 I can import these using the batch import. On Dspace 1.5.2 however, I get 
these Lucene errors and import fails. The map files get written but remain 
empty (0K). This also happens when I batch export items from the 1.5.2 install 
and then batch import them.

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.lucene.index.

Any ideas whether this is related to Windows?
