Event handling... inner classes or not? what do you recomend?

Me question is should you
use
JButton addbutton=new JButton("Add");
addbutton.addNewActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
or this
class Window implements ActionListener
public void actionPerformed(ActionEvent e)
if (e.getSource()==addbutton)
if (e.getSource()==...
So when I would have say menu and 15 menuitems to listen, I would prefer the innerclass system becauses it somehow produces cleaner code, but it creates pretty much of those $1 $2 files... will it be a problem?

I prefer to use inner classes since it makes clean code.
However I prefer to define one innerclass per source
type and not the getSource() trick. This gives a clean
separation of responsability. You can use the same
innerclass for different sources if the reaction should
be the same for different user inputs.you mean something like this:
Button b1=new Button("Edit1");
Button b2=new Button("Edit2");
b1.addActionListener(new InnerClass(b1));
b2.addActionListener(new InnerClass(b2));

There should be no issues. Its designed to work like that. You don't change Apple IDs just because you get a new device.

Unlikely. But nothing is impossible. Though I don;t see how that would happen. As long as both are signed into the Same Apple ID / iCloud Account they will be N'Sync. (Bad Joke)

If I get a message or buy an app or take a photo on the iPhone 5, how do I get those things onto the iPhone 6?
If you buy an App, you have 2 ways to get it to the iPhone6: If Automatic Downloads is enabled in Settings->iTunes & App Store, it will automatically download to the iPhone 6 when you buy it on the 5 and vice versa if you buy it on the 6, it will download to the 5.
Alternatively, you can simply go to the App Store App->Updates->Purchased and look for the App there and download it. Purchased Apps will not require payment again. i.e They'll be free to download to the iPhone 6 once purchased.
SMS Messages will sync over using Continuity as long as they are on the same Wifi network. Otherwise, restoring the iPhone 5 backup to the iPhone 6 will transfer all messages received up until the backup was made onto the iPhone 6.
Images, can be transferred either through Photo Stream
My Photo Stream FAQ - Apple Support
Or any Cloud service you want such as Dropbox, or One Drive.

Also, something i forgot to ask initially: Should I update the iPhone 5 to iOS 8 first or does that not matter?
If you want the Continuity features as explained above you need to update the iPhone 5 to iOS 8. Otherwise its not all that important.

How to config POF to handle inner class

Hi, I have the following vo object:
public class Obj implements java.io.Serializable, PortableObject
public static class InnerObj implements java.io.Serializable, PortableObject
1) If i put both classes in the pof config xml, it throws class not found exception for the inner class InnerObj (as expected since there is no separate class files for it). My question is what is the correct way to handle the inner class? Should i just leave it out of the pof config xml and coherence will be smart enough to handle it?
<pof-config>
<user-type-list>
<user-type>
<type-id>111</type-id>
<class-name>some.package.Obj</class-name>
</user-type>
<user-type>
<type-id>222</type-id>
<class-name>some.package.InnerObj</class-name>
</user-type>
</user-type-list>
</pof-config>
2) Also want to confirm if implement both java.io.Serializable & PortableObject in the vo, coherence will ALWAYS take the portable object serialization if <pof-enabled>true</pof-enabled> is set in the config?
thanks!

Hi i got the inner class config to work but now struggling to get it to run from the java client that connects to the cache. Went through the documents, it only made me more confused, so many config files...
The exception i am getting now is from the java application that connects to the cache, when it tried to do a cache.putAll() it's throwing the following exception:
An exception occurred while encoding a PutAllRequest for Service=ExtendTcpCacheService:TcpInitiator: java.io.IOException: unknown user type: some.package.Obj
So far I have done the below to enable POF:
1) On cache server I made the below changes, and both the cacheserver and extendproxy are running fine now.
- changed xml to: <pof-enabled>true</pof-enabled>
- dropped the jar containing the pof objects in the classpath
- added override pof config xml:
<pof-config>
<user-type-list>
<user-type>
<type-id>8888</type-id>
<class-name>some.package.Obj</class-name>
</user-type>
<user-type>
<type-id>8889</type-id>
<class-name>some.package.Obj$InnerObj</class-name>
</user-type>
</user-type-list>
</pof-config>
2) On the java project that connects to the cache:
- changed -Dtangosol.coherence.cacheconfig xml file and added:
<defaults>
<serializer>pof</serializer>
</defaults>
I am sure i am missing some config somewhere, thank you for your help.

Event handler of inbound plug not called when plug fired by event handler

Hello All,
I have a rather bizzare problem, hopefully someone out there can figure out what is going on, as I'm rather stumped.
I have 2 views, A and B. They are linked by plugs, InA, InB, OutToA, OutToB. OutToB is linked to InB from A to B, OutToA is linked to InA from B to A.
There is an onActionLink in view A. Clicking on this triggers an action which calls the wdFirePlugOutToB method.
In view B some handling is done in the method onPlugInB, then wdFirePlugOutToA is called to change the displayed view back to A.
As far as the user is concerned they don't ever see view B. (this bit works perfectly!)
Now also in view A I have an event handler which handles a event from the component controller. It also calls wdFirePlugOutToB.
If I trigger an event in the component controller this event handler is called and the method called. However, when I put a breakpoint in the onPlugInB, flow never reaches here. Flow does get to the wdDoModifyView of view B but never to the inbound plug event handler.
Any suggestions as to what I might need to do? I would have thought calling the wdFirePlugOutToB method would ALWAYS trigger the linked event handler onPlugInB.
I am running NW04 SP18.
Thanks!

Hi Bharathwaj,
The project I'm working on has a requirement to allow for a road-mapped process (FPM) which has one step in which multiple screens can be accessed. I'll give an example: A user in step A selects the cost centre that they want to work with, in step B they need to maintain several pages of information about this cost centre. The do not want to break this information into steps, as there is no logical progression from one step to the next, and it may well be that the user wishes to go from maintaining screen 1 to screen 3, and then screen 2, and then screen 4. Stepping between all screens (1->2->3->2->3->4) wastes time and is not very user friendly. Step C of the process confirms the data that the user entered in step B, and Step D is the validation that the changes have been committed to the database. (a very familar 4 step process for those using ESS).
To allow for this requirement, I have designed a left navigation pane type screen. links appear on the left of the screen and the user can use these to navigate between different screens (implemented as FPM IVAC VCs) on the right of the screen.
It is quite an elegant solution (even if I do say so myself although quite complex to implement. I have relied very heavily on reading the code SAP put together for the FPM. The most complex part is that in order to update the the content of view containers in an application you must trigger a web dynpro view navigation by firing a plug to a different view.
Unfortunately I don't have any sample application code, only the finished product, which I can't really share. But I can say that if you look at the FPM code carefully, working from where the wdInit of the FPM is called, it will eventually make sense.
One thing I found slightly frustrating, you can't use the FPM's component usage register (FPM method attachComponentUsage(IWDComponent, IWDComponentUsage)) to add a VC... darned inconvienient really (you'd think that the web dynpro framework could have implemented the concept of extending an interface, but the IBLC and IVAC interfaces are different! - even though the IVAC is just IBLC + a few methods), but then again you can manage the instantiation of the used VC yourself and call the onInit method of the VC passing the current fpm reference, to attach it to a common FC, and given that you should be sharing context through the FC and never the VC, then really this isn't too much of an issue. (I spent ages worrying that I couldn't add the instances of the VC that I was using within my navigation pane VC to the fpm instance list, until I realised that it really didn't matter!)
One day - when I have time (yeah right!) I might put together a blog about this sort of stuff, in the meantime, it keeps me plenty busy enough not to have the time!
Hope this helped in some small way,
Cheers,
Chris

Event handling from class to another

i get toolbarDemo.java which make event handling to JTextArea in the same class
http://java.sun.com/docs/books/tutorial/uiswing/components/example-1dot4/index.html#ToolBarDemo
but i have another class and i make object of toolBar class and i move toolBar icons only how can i move the event handling as open ,save,copy,paste to my another class
i want to ignore actionPerformed of toolBar class and listen to my another's class actionPerformed
thanks

Rather than trying to use the ToolBarDemo class as-is you can use/modify the methods in it for your own class, like this:
import java.awt.*;
import java.awt.event.*;
import java.net.URL;
import javax.swing.*;
import javax.swing.text.TextAction;
public class ToolBarIconTest implements ActionListener
    static final private String OPEN = "open";

    static final private String COPY = "copy";
    static final private String PASTE = "paste";
    public void actionPerformed(ActionEvent e)
        String cmd = e.getActionCommand();
        if (OPEN.equals(cmd))
            System.out.println("show a JFileChooser open dialog");
        if (SAVE.equals(cmd))

Event handling across classes

I have a (newbie?) question regarding event handling:
I have a database class which has an update method and invokes a databaseGUI class to display the data:
/// databaseClass instantiated as DatabaseClass dataConn = new DatabaseClass()
public class DatabaseClass {
     Public void updateData {
     // write values to database
     Public void showData {
        thisDBGUI = new databaseGUI();
        // populate screen with data from database through database GUI class
        // add a button to the interface via addUpdateButton method of databaseGUI class
        thisDBGUI.addUpdateButton();
/// databaseGUI class
public class databaseGUI extends JFrame implements ActionListener {
     public void addUpdateButton() {
        buttonPanel = new JPanel();
        updateButton = new JButton ("Udpate Record");
        updateButton.addActionListener(this);
        buttonPanel.add(okUpdate);
     public void actionPerformed(ActionEvent e) {
         // need to call dataConn.updateData method
}Please forgive the incomplete snippets; everything displays perfectly and the code executes fine EXCEPT I do not know to use the actionPerformed method to execute the updateDatabase method on the dataConn instance. Any help is greatly appreciated!
David Erickson

Personally, I would move the actionlistener into the DatabaseClass.I agree, but I would do it a different way (just due to personal preference):
public class databaseGUI extends JFrame {
     public void addUpdateButton(DatabaseClass dbc) {
          buttonPanel = new JPanel();
          updateButton = new JButton ("Udpate Record");
          updateButton.addActionListener(dbc);
          buttonPanel.add(okUpdate);
     }Then, just pass a reference to "this" when you call databaseGUI's constructor.
I just like this method better because the GUI object is still setting up the entire GUI on its own. Personal preference, no more.

Inner class or not inner class??

Hi, I've a little problem:
I want to create bonus objects for my game, all bonus can appears casually during the time of game, so they can be visibles or not visibles.
If I pick a "bonus cherry", one life is give to the player
If i pick a "flower bonus", invincibility is give to the player etc etc..
So, how to build the bonus class??
I've to define a class with common methods (visibility and animation) and than inner class "cherry" and "flower" ? and they have to be static or not static?
or I've to implements a bonus interface??

- boolean isVisible

and than inner class "cherry" and

APT and inner classes does not work.

Hi
Am I the only one who cannot make APT process local classes in methods, or anonymous classes. The are not declared in the APT definition of declared, but nor are they included!
Also, has anyone had problems in that anonymous classes cannot be annotated using annotations, because there is no syntactic place to add metadata.
But even so, I should like to process annotated methods in local or anonymous classes.
-- Kasper

By design anonymous and local classes are not visible in apt as the interiors of methods and constructors are not exposed.

You can't use Boot Camp in 3 TB drives. You can download VirtualBox, Parallels or VMware Fusion and install Windows on a virtual machine. See > https://discussions.apple.com/docs/DOC-3321

OT what would you recomend?

HI!
I have a form with four date fields Hotel, Arrival date,
Departure date
Airline Departure Date etc.
I would like to get a Calendar date picker or date chooser to
input the date
into the fields and insert to database.
I do not want a pop up window and I would like to input the
date as 3
fields, Field: Arrival_Month, January, Field: Arrival_Day 15,
Field:
Arrival_Year, 2008
Do you have a favorite you can suggest. Thanks for your
input.
Dave

There may be a control to hide the list when the calendar
appears - there is
on Boxover. But the easiest solution is to move either the
calendar or the
list.

My iphone fall in recovery mode many times, I used Itunes to try that solutions the problem but nothing work. What do you recomend?

I have a problem with my iphone 4, it fall in recovery mode every hour in a day and working very slowly. I actualised the itunes, but nothig work. Can anybody help me?

I don't know if anyone could help. My phone does not give that error message anymore. This is what usually happens first, where it keeps waiting for iphone:
http://flic.kr/p/fXYEVN
and then, I get this error message:
http://flic.kr/p/fXYAwX
During the whole time, my screen stays black (a hint of the blacklight) but no apple logo, no sound, no "connect to itunes"
I just want this to work. Any ideas? I am pretty much up for anything

Inner Classes - when to use with Swing?

Hi again,
I was creating a GUI with JTabbedPane as content pane, while doing the single panes in the different tabs i started wondering about some design issues.
Let�s say you have a pane that is composed of 3 "subpanes" ( containing all the interaction components ). Should i write "normal" classes for each of the subpanes or is it more reasonable to define them as inner classes of the "main" panel - that�s at least what i thought because those 3 smaller panels are bound to the main panel for their lifetime...
Any design tips about inner classes and swing or even inner classes in general, i�d really appreciate.
Thx

The concept of inner classes design in java is (I hope) they provide 'composite aggregation' relation with the contained class.
Means that the (inner) class cannot exists alone and provide functionalities like other classes. Inner classes refer to the "contains" relationship in the UML.
The other regular associations say, having a value oject model to an UI are Structural Aggregation, means that the value object can be used in the UI and also separately.
For your case the inner classes are not suitable. You may have to find a suitable mechanism to get the individual tab panes. Probably use an interface to bridge the three tab panes and use an manager class, pass and id to the manager class and get the required Tabbed pane.
Thanks,
ananth

[Create Login] Provisioning Error: event handler/adapter could not be found

Hello,
I am running a fresh install of OIM 9.0.3 (installed yesterday) on a Windows XP Machine running:
Weblogic 813 SP6
JDK142 11,
MSSQL 2000 SP3a I have a test resource, a simple MSSQL Table with a few fields, which I used the connector pack to install and connect. I imported the resource without any issues. However, when I attempt to Create Login on the resource, it gives me the following error:
"An error occurred while retrying one of the tasks
Create Login: Event Handler not found"When I check the details of Create Login (in my To-Do List for xelsysadm):
Error Details
The class file for event handler/adapter "adpDBCREATELOGIN" could not be found.I am very new to this system, and I really don't know where to begin trouble shooting this issue. Any ideas on what might be wrong with the system? It could be anywhere from missing a step in the beginning of the installation to doing something incorrectly. Any pointers on where I can start troubleshooting as to why I can't provision would be very helpful and much appreciated!
Thanks

Did you compile the adapters? When you import them from XML they must be compiled before you can use them. Go to the Design Console -> Dev tools -> Adapter Manager and compile them there.

A minimal public class in a file named "Minimal.java" in the directory named "minimal":
package minimal;
public class Minimal {
private int variable;
public Minimal(int var) {
variable = var;
public int getVariable() {
return variable;
}This would be an example of adding an inner class:
package minimal;
public class Minimal {
private int variable;
public Minimal(int var) {
variable = var;
public int getVariable() {
return variable;
public class Inner {
private int innerVariable;
public Inner(int var) {
innerVariable = var;
public int getInnerVariable() {
return innerVariable;
}The inner class is exactly like any other inner class except if you are accessing it from anything else other than Minimal then you would have to add Minimal. right before Inner for example, where the Minimal class could use
Inner inner = new Inner(5);other classes would have to use
Minimal.Inner inner = new Minimal.Inner(5);
See [Inner Class Example|http://java.sun.com/docs/books/tutorial/java/javaOO/innerclasses.html] or [Nested Classes|http://java.sun.com/docs/books/tutorial/java/javaOO/nested.html] for more information.
He is probably not asking what an inner class is or how to declare one in raw source code. To me he is asking how do I
explain this relationship in a UML diagram and as UML is not and exact science and expression can vary a lot
between UML design applications I didn't want to stab in the dark.
@OP I would say whatever seems most logical to you and your team, write something that reads.

Event handling... inner classes or not? what do you recomend?
