Usually with NullPointerExceptions, it's always produced when you are accessing a reference that has not yet been initialized. Take for example, a Person.
public static void main(String[] args){
Person someone = null;
someone.setName("Last", "First", "Middle");
}
here, the NullPointerException will result since someone has not yet been initialized. In most cases, it's a needed object has not yet been created. Maybe the Connection in the DB has not yet been created with the use of the static method DB.connect(<params>)? As for the the truncation error, i'm not so sure how to answer that... maybe some other peeps here can help. =P (oracle guys perhaps?  )
