• Passing DataSource object from a servlet to a JavaBean

• Modifying the Codec List Object in an ASF file

  - by scompt.com

  Is it possible to modify the Codec List Object in an ASF file? In particular, I would like to edit the codec name and description. I realize that this won't actually change the content of the video, but it's necessary for the video to be verified by an external tool. Does anyone know of a tool that will allow me to do this? If not, does anyone have any suggestions about how I might go about doing it using the Windows Media Format 11 SDK?

• LinkedList insert tied to inserted object

  - by wrongusername

  I have code that looks like this: public class Polynomial { List<Term> term = new LinkedList<Term>(); and it seems that whenever I do something like term.add(anotherTerm), with anotherTerm being... another Term object, it seems anotherTerm is referencing the same thing as what I've just inserted into term so that whenever I try to change anotherTerm, term.get(2) (let's say) get's changed too. How can I prevent this from happening?

• What is the role of the Router Object in MVC based frameworks

  - by Saif Bechan

  In most MVC based framework I see a router object. If I look at it splits up the uri and decides what controller should be used, and which action should be fired. Even though this makes a lot of sense, I can not give this a place in the MVC patern. Is splitting up the uri not the job of the controller. And then the controller should just decide which class and function to run.

• Why Isn't My .Net Object Serializable?

  - by Rob P.

  I've got a 'MyDataTable' class that inherits from System.Data.DataTable I've implemented ISerializable in my class and have a 'Public Overrides Sub GetObjectData...' But when I try to serialize the an object of 'MyDataTable' I get an error saying that 'MyDataTable' is not marked as serializable. If I used a DataTable instead - my code serializes correctly. If I add a serializable attribute to the 'MyDataTable' class - it serializes correctly, but I'm told that is unnecessary if I implement ISerializable. Can someone point me in the right direction?
