sqlException when use ActiveJDBC

Question

I use ActiveJDBC and Oracle 11g DB. When I use saveIt, i get java.sql.Exception. When I get instance or list of it, everything ok. What I do wrong?

Exception in thread "main" org.javalite.activejdbc.DBException: java.sql.SQLException: Invalid argument
зове, query: INSERT INTO dept (DEPTNO, DNAME, LOC) VALUES (?, ?, ?), params: 45, sdfa, fdg

Caused by: java.sql.SQLException: Invalid argument

And here is my code:

public void addPersistence() throws IOException {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        Dept d = new Dept();
        String value;
        for (String s : getAttributesNames()) {
            System.out.println("Enter " + s + " and press Enter button:");
            value = reader.readLine();
            d.set(s, value);
        }
        d.saveIt();

    }

public List<String> getAttributesNames() {
        return Arrays.asList("DEPTNO", "DNAME", "LOC");
    }

The reason of the probleb is that ActiveJDBC uses id column as a Primari Key in table for recognizing which operation - INSERT or UPDATE should be used. And if table doesn't has such column, programmer should specify PK manually using @IdName("nameOfColumn") annotation. More information you can find here
