Hi everybody,
I am working on REST module for DSpace. In my servlet I am using the following
code to access the list of communities (simplified):
Context context = null;
context = new Context();
Collection[] communities = null;
communities = Collection.findAll(context);
It is not working (communities not initialized), and after checking with
exceptions I have got the following message:
org.postgresql.util.PSQLException: ERROR: relation "handle" does not exist
If there are no communities then variable communities is initialized and
contain 0 elements. So, this is as expected.
I am using it on dspace-dao-prototype which is still in development phase.
Has someone idea what may be causing this, or to point me in right direction
where to find error further?
Thanks
Bojan
