hi ! I want to set up an initialization script, and i must, in a first part, check if the appengine datastore is empty. I tried to send a query, with :
query.setUnique(true); if(query.execute()==null) But it throws a null pointer exception. How to check that my datastore is empty ? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
