Hi, I'm running dspace 3.0 using xmlui.
I recently had to make a change to AbstractAdapter.java as I needed a
change in my mets. I'm adding a "fake" fileSec section for certain
items. I run a simple db query via the DatabaseManager class to
determine which items.
Context context = new Context();
String query = "select metadatavalue.text_value from metadatavalue where
item_id=" + item_id + " and metadatavalue.metadata_field_id=1";
TableRow row = DatabaseManager.querySingle(context, query );
String result = row.getStringColumn("text_value");
Now I am getting this error a lot.

I assume this has to do with the Context? Is there a better way of
running my query or resolving my issue ?
