    public static void main(String[] args)

I know I am four years behind on this, but I finally found out how I resolved my problem (hence why I am on this thread).

I created my table using the database script editor. I used double quotes around my table. I found this out when I went to the service tab (netbeans), and right clicked on my table to view data. I got this:

select * from {schema}."{table}"

So, I thought I would translate that to my java. And, Bingo. Hopefully this will shed some light on your application, I copied and pasted some of your code and hopefully this will work.

public class Db {
    private final String url = "jdbc:derby://localhost:1527/{db}";
    private final String tab = "{schema}.\"REST\"";

    private static Connection createConnection() throws Exception {
         Connection conn = null;
         conn = DriverManager.getConnection(url);
         return conn;
    }

    private static void insertRestaurants(int id, String restName, String cityName)
    {
        try
        {
            Connection conn = createConnection();
            stmt = conn.createStatement();
            stmt.execute("insert into " + table + " values (" +
                    id + ",'" + restName + "','" + cityName +"')");
            stmt.close();
        }
        catch (SQLException sqlExcept) 
        {
            sqlExcept.printStackTrace();
        }
    }
}

Cheers!

Table names are case sensitive. Make sure the table you created is actually called "REST" with all caps or if it's "Rest" or "rest".

I had the same trouble with embedded db and finally cleared the same .This will help you for sure aparna-java.blogspot.com please check this

A simple example @ http://javabyranjith.blogspot.in/2016/08/apache-derby-with-java-example.html. Hope it can be helpful

I did the following fix, using Eclipse:

(In Database Perspective: Window>Perspective>Open Perspective>Other>Database Development), right clicking Database Connection folder>New>Derby:

You have to make sure the 'Database Location' folder is at the same location as the Derby.jar location mentioned at (Edit Driver Definition>JAR List). Like see below snapshot:

Derby Jar Location

Derby DB Location

Hope this helps.

You might find it easier to learn Derby by starting with the Derby tutorials: http://db.apache.org/derby/docs/10.7/getstart/cgstutorialintro.html
