Documentation for abstract classes (Behavior and Binding) ?

Hi,
I am looking at the beautiful sample-app made by Jasper Potts at the www.fxexperience.com. ("Javafx 2.0 Audio Player")
There some abstract classes are used, for Behavior and Binding.
It turns out that I have difficulties finding documentation for those classes. The classes are:
com.sun.javafx.scene.control.behavior.BehaviorBase;
com.sun.javafx.scene.control.behavior.KeyBinding;
Could anybody give me hint, pls, where I could find documentation for those classes.
They are all in the JavaFx-Runtime-Jar-file, together with all the Javafx-classes.
The Javafx-classes are pretty well documented in the meantime.
But, allthough in the same "package", the com.sun... classes are still black boxes to me.
Appreciate a link from somebody who knows, pls.
Hans

Hi Hans,
the classes in the com.sun.* packages are internal classes, in other words they are meant to be black boxes for you. :-)
A developer should not use these classes, because they can change anytime without warning, even between minor releases. But a developer should also not need to use the internal classes. If Jasper needed them in the demo, it is a clear indicator that something is missing in the public API.
The classes seem to be part of the UI controls, which were already open-sourced. If you just want to play with the classes, you can study the sources. As a long term solution, I suggest to add a feature request in JIRA for the parts you are missing in the public API (http://javafx-jira.kenai.com).

Documentation for oracle webcenter wiki and blog server 10.1.3.2.0

Hi
Can anyone tell me where I can get the documentation for oracle webcenter wiki and blog server 10.1.3.2.0. I am specifically interested in this version and not the latest version Oracle® WebCenter Wiki and Blog Server 10g Release 3 (10.1.3.4.0) because I have heard the older version provided out of the box portlets for creation of blogs.
Since we want blogs very fast, I want documentation of this older version.
Can anyone point them out to me as soon as possible please

You can find the demo portlets here: http://www.oracle.com/technology/products/webcenter/owcs_10132_demos.html#wiki_blog_disc_samples
I do not believe there were any portlets provided with the earlier release.
Anyway what i think is it should not take you more than a few hours to integrate blogging functionality if you are using the Connection & Task flows provided by WebCenter.

Documentation for the As-Is and To-Be process.

Can any one send some material regarding how to write documentation for the AS-IS and TO-BE business process for the business blue print.
My requirement is to <u>automate the process which are receiving goods from the gate entry to GR level and finally posting goods issue</u> all should done automatically .
Now we are gathering information from the client according to their business process.
Our client is digital meter product based company.
Its an urgent thanks in advance.

Probably the best thing to do is go to your boss/team lead/project manager/client contact and ask them what documentation they want you to produce and what should go in it. No-one here can guess at that.

What are abstract classes/methods and what are they for?

Hi,
I've just heard about abstract classes and methods and I'm just wondering what exactly they're used for, and why are they there for the Graphics class for example?
Cheers.

Cheers.Hey bro, I'll try to solve your problemYou have to know two important concepts for this part. 1 is Abstract classes and the other is Interface classes. Depends on the nature of the project, you need to set certain level of standards and rules that the other developers must follow. This is where Abstract classes and Interface classes come into picture.
Abstract classes are usually used on small time projects, where it can have code implementation like general classes and also declare Abstract methods (empty methods that require implementation from the sub-classes).Wrong, they are used equally among big and small projects alike.
Here are the rules of an Abstract class and method:
1. Abstract classes cannot be instantiatedRight.
2. Abstract class can extend an abstract class and implement several interface classesRight, but the same is true for non-abstract classes, so nothing special here.
3. Abstract class cannot extend a general class or an interfaceWrong. Abstract classes can extend non-abstract ones. Best example: Object is non-abstract. How would you write an abstract class that doesn't extend Object (directly or indirectly)?
4. If a class contains Abstract method, the class has to be declared Abstract classRight.
5. An Abstract class may or may not contain an Abstract methodRight, and an important point to realize. A class need not have abstract methods to be an abstract class, although usually it will.
6. Abstract method should not have any code implementations, the sub-classes must override it (sub-class must give the code implementations). An abstract method must not have any implementation code code. It's more than a suggestion.
7. If a sub-class of an Abstract class does not override the Abstract methods of its super-class, than the sub-class should be declared Abstract also.This follows from point 4.
9. Abstract classes can only be declared with public and default access modifiers.That's the same for abstract and non-abstract classes.

Abstract class, Interface and two models issue

Hi!
I will post my code and then ask the question (text between code snippets is bold, so you don't miss it, it's not shouting):
public class AppScreen extends JFrame
                       implements ActionListener {
private MemoryTableModel model;
public AppScreen() {
    this.model = new MemoryTableModel();
       //code
public void actionPerformed(ActionEvent actEvt) {
      if(table.getSelectedRow() != -1) {
        model.deleteRow(table.getSelectedRow());
      else {
        ErrDialog.noRowErr();
public MemoryTableModel getModel() {
    return model;
public class MemoryTableModel extends BasicTableModel
                              implements MemoryTableInterface {
public MemoryTableModel() {
    //code
public synchronized void insertRow(String file, String time) {
    //code
public synchronized void editRow(int selectedRow, String file, String time) {
    //code
public synchronized void deleteRow(int selectedRow) {
    //code
public abstract class BasicTableModel extends AbstractTableModel {
private final String FILE_COLUMN = "Executable file";
private final String TIME_COLUMN = "Time";
protected String[] columnNames   = new String[2];
protected List<RowRecord> data   = new ArrayList<RowRecord>();
BasicTableModel() {
    //code
public int getColumnCount() {
    //code
public int getRowCount() {
    //code
public String getValueAt(int row, int col) {
    //code
public Class<? extends String> getColumnClass(int c) {
    //code
public String getColumnName(int col) {
    //code
public List<RowRecord> getData() {
    //code
public int getTimeColumn() {
    //code
public int getFileColumn() {
    //code
public interface MemoryTableInterface {
public void insertRow(String file, String time);
public void editRow(int selectedRow, String file, String time);
public void deleteRow(int selectedRow);
In this form, everything works fine. But now, I would like to choose between two models at the start, so I thought I would do this:
public class AppScreen extends JFrame
                       implements ActionListener {
private BasicTableModel model;
public AppScreen() {
    if(...) {
      this.model = new MemoryTableModel();
    else {
      this.model = new JDBCTableModel();
public void actionPerformed(ActionEvent actEvt) {
      if(table.getSelectedRow() != -1) {
        model.deleteRow(table.getSelectedRow());
      else {
        ErrDialog.noRowErr();
public BasicTableModel getModel() {
    return model;
public class JDBCTableModel extends BasicTableModel
                            implements JDBCTableInterface {
public JDBCTableModel(Connection conn)
    throws ClassNotFoundException, SQLException {
    //code
public void insertRow(String file, String time) throws SQLException {
    //code
public void editRow(int selectedRow, String newFile, String newTime)
      throws SQLException {
    //code
public void deleteRow(int selectedRow) throws SQLException {
    //code
public interface JDBCTableInterface {
public void insertRow(String file, String time) throws SQLException;
public void editRow(int selectedRow, String file, String time)
      throws SQLException;
public void deleteRow(int selectedRow) throws SQLException;
}But I'm getting error message from AppScreen that method deleteRow(int) is undefined for the type BasicTableModel. I thought if I initialize variable model as some implementation of BasicTableModel, it will be OK. Apparently it's not, so:
where and what am I missing or
how can I realize this choosing between two models so I don't have to write "if(model == MemoryModel) else if(model == JDBCModel)" around every method where I have to decide.
Thanks!

I would like to have issues interfacing with two classy models, as well. ;-)
You need to have your BasicTobleModel class implement your JDBCTableInterface interface (even if it doesn't implement those methods itself), if that is how you intend to use that class.
Edit: Too slow.

Documentation for XSQLRequest class

Where can I find documentation for the XSQLRequest java class?
I have code that attempts to process an XSQL page as follows:
XSQLRequest xsqlReq = new XSQLRequest(pageURL);
xsqlReq.process(params,pwOutput,pwError);
I'm getting the "out of memory" error that has been reported by others - looks like I'll have to figure out how to use SAX instead of DOM, but I first want to understanding what's going on with the existing code.

Steve,
Thanks for the info. The problem is the amount of data that is retreived. I can make it work by reducing the amount of data retrieved, but as I increase the amount of data, it eventually fails.
Is there any straight forward solution? It's so easy and convenient using the XSQL page processor via XSQLRequest - I'd hate to have to abandon it.
Thanks,
Matt
PS - Great book!!!

Abstract classes, Interfaces, and concrete classes

I have another technical interview tomorrow and somehow I keep getting asked the same question and I feel my answer is not really up to par. The question is:
"What is the advantage of subclassing an abstract class versus concrete class?"
"What is the difference of using an interface versus an abstract class, which is better to use?"
For the first question, I usually answer performance is the advantage because you don't have to instantiate the class.
For the second question, I usually say that you can put implementation in an abstract class and you can't in an interface. I really can't answer the second part to this question.
Any ideas?

For the first question, I usually answer performance
is the advantage because you don't have to instantiate
the class. Try invoking the class B in the following somewhere in another class.
abstract class A{
A(){
System.out.println("abstract instantiated");
class B extends A{
B(){super();}
}

How to implement the abstract classes MessageDigest and Signature?

Hi all,
I've recently started working on JCDK 2.2.1.
I have a problem to share and get suggestions from you!
My aim is to implement ECDSA on Java card
I have seen the Javacard API and tried to program using the classes
MessageDigest and Signature. They are abstract classes and except the
Method getInstance in them, the rest of all methods are declared abstract.
Does that mean we have to give definition for them or else can we use
them as they are?
I tried giving some definitions, but to my surprise there's no such
initiation of any variable to the algorithm we provide in the method
"getInstance"! Then, it's not possible to give defn,. for other
methods like getAlgorithm, reset, etc. How can we resolve this ?
Any ideas?
Regards,
Johnbuchk

API for Course, Class, Enrollment and Attendance

Dear Guru
My client has custom learning management (OAF Page) and Oracle Learning management as well.
Enrollment process and marking attendance are currently done in custom developed pages. At the same time they update the enrollment and attendance in OLM as well.
Now they want to integrate the custom pages to OLM, means they like to update the class, enrollments & attendance through API in OLM.
Please tel me, does OLM has API for creating Course, Class, Enrollment and Attendance.
Thanks in advance.

Please see these docs/links.

Table link for Internal Class no. and Equipment no.

Hi PM Experts,
I am facing a problem while creating a report for Equipment characteristic values report.
The problem is that Equipment characteristics are updated through BDC. So when I am trying to link the table EQUI and AUSP as
EQUI_EQUNR = AUSP_OBJEK, which normally in standard systems are equal. But in our system as characteristics are updated through BDC, so AUSP_OBJEK contains some other object. So please help to get relation between equipment and Internal class number
Regards
San

San,
Creation through BDC wouldn't change the value.The value should be the same.However be aware that that you will not be able to link these two table fields directly in select statement since the field types are different. Just move the equipment number to a field of type AUSP-OBJEK and then do the select.
Regards
Narasimhan

Looking for Smart Playlist Documentation for iTunes Match (iCloud), and iOS

With iTunes Match I don't understand exactly how Smart Playlist's are suppose to work with iTunes Match (iCloud) and my iOS devices. I am looking for some official (possibly draft) documentation.

Is this a general rant or do you have a specific question ?

Documentation for Oracle XML parser Classes and Interfaces

I would like to use the oracle XMLParser V2 classes with JDeveloper 3.1, but I cannot find any reference documentation for the classes and interfaces in help.
I am especially interested in a documentation for the XSLProcessor class. The only information I found was provided with the few provided samples.

I don't think the javadoc for this was included in the release. You can get the Javadoc (as well as the latest version of the XML Parser v2) here on OTN.
Take Care,

Documentation formats for interfaces, classes, abstract classes

I am writing docs and want to make sure it conforms to best practices. Here is what I am doing:
interfaces = [italics, not bold]
classes = [not italics, bold]
abstract classes = [italics, bold]
I am most unsure of abstract classes?
That is important to me, so please help me get this straight. thanks.

Everybody knows that interfaces are blue, classes are red, and abstract classes use jumpy text.
(that was a joke by the way)
To my mind, using bold for abstract classes would be misleading. Just on an intuitive level, bold seems more concrete. But that's just me. I think the best thing to do is just to decorate the names with "<<interface>>" or "<<abstract>>" so there's no confusion.
