Look at that line ...(ResultSet) Repository.getServiceRegistry(..., then look at your exception and finally at your imports. There you will see that ResultSet is actually java.sql.ResultSet (which is indicated by your ClassCastException's message).

If you then look at the super classes or interfaces of org.alfresco.repo.search.impl.lucene.PagingLuceneResultSet I'd say you won't find any java.sql.ResultSet. That's why you get that exception.

Because you imported java.sql.ResultSet instead of an alfresco class/interface compatible to org.alfresco.repo.search.impl.lucene.PagingLuceneResultSet
