I see my Postgres DB, when I’m doing SELECT query to the table, then I get a warning:

permision denied for relation whitelist.

Does the warning on Postgres is the cause of this error?

    Only assuming as you haven’t posted any Java code but looks like your NullPointer which is probably a ResultSet which dosen’t contain any results is because you don’t have the right permissions to read/write onto the relation ‘whitelist’. I’d check what username your using to login to the database against which username your using for the jdbc connection.

    If you post your java code we can see if the NullPointer is because of an empty result set which you are then trying to manipulate or because of something else.

    First question i’ve answered so sorry if its wordy.
