von java aus datenbank füllen

[Hm...]

public static void InMySQL(String[][] args, String unischrift){  
	try{  
		   Class.forName("com.mysql.jdbc.Driver");  
		   }  
		   catch (ClassNotFoundException e){  
		   System.out.println("Kann nicht geladen werden");  
		   return;  
		   }  
		   try{  
		   Connection con=  
		   DriverManager.getConnection(  
		   "jdbc:mysql://localhost/bib");  
		   Statement stmt=(Statement) con.createStatement();  
		   String bef;  
		   /\*String autor="Kant";  
		   String titel="Kritik der reinen Vernunft";  
		   int jahr=1965;\*/  
		  
		   bef="insert into " + unischrift  
		   +"(CustomID, Bisheriger Nutzen , Zeitraum) "  
		   +"values (\""+args[0][0]+"\", \""+args[0][1]+"\", \""+null+"\")";  
		   //System.out.println(bef);  
		   ResultSet rs=stmt.executeQuery(bef);  
		   rs.close();  
		   stmt.close();  
		   con.close();  
		   }  
		   catch (SQLException se){  
		   System.out.println("SQL Fehler "+se.getMessage());  
		   se.printStackTrace(System.out);  
		   }  
		  
}  

ich benutze diese methode um die tabelle zbiscgrift der datenbank Customer zu füllen, bekomme aber diese exception:
