What exactly is a Connection Factory ?
I'm still struggling with what a "connection factory" exactly is.
We have a custom API and the first thing that we need to do, is obtain a connection from the connection factory.
They say me that a connection factory is a "java base class"; but what does that means?

What's the advantage of creating an object via a connectionFactory, while the same could be achieved by creating just an instance of an object?Creating an instance of an object using "new" restricts you to creating just one type of Object - the type of the ctor you call with new.
A Factory can return different runtime types without the user having to know. The factory's create method usually returns an interface or a superclass type. Unbeknownst to the user, the factory can decide to create a return a subclass or a different implementation of that interface.
Now you have to make a ConnectionFactory class and implement a createConnetion method. Thereafter you have to instantiate an instance of the connectionFactory class, and call the createConnection method.
This is a lot more work then just doing Connection connn = new Connection(.....);but all you can create with new is Connection. Factory is more flexible.

What exactly is the "cell factory?"
So I've been seeing this term a lot on the forums, as well as http://docs.oracle.com/javafx/2/ui_controls/table-view.htm and on the ensemble, but I'm not 100% sure what it is.... It seems like just a method to set data into your tables, like the table model? Anyone have a more in depth explanation than the one in the docs, I would appreciate it!!!
Thanks,
~KZCell factories create cells. A cell is a Labeled Node which contains some extra properties and methods for maintaining an editing and selection state and a link back to a cell value. Cells are used in a few places in JavaFX, for example in ListViews and TableViews, as well as TreeTables and ComboBoxes. The Cell is the visual representation (Node) which corresponds to a backing data item. The trick is that there is not necessarily a static one to one correspondence between cells and data values.
Let's take an example. Here is an empty ListView in a Scene. When I run the app, it displays the ListView at it's preferred height, with 17 rows.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.layout.*;
import javafx.stage.Stage;
public class ListViewSample extends Application {
@Override public void start(Stage stage) {
ListView listView = new ListView();
VBox layout = new VBox();
VBox.setVgrow(listView, Priority.ALWAYS);
layout.getChildren().addAll(listView);
stage.setScene(new Scene(layout));
stage.show();
public static void main(String[] args) { launch(args); }
}Each one of those 17 rows is empty. No Cell Factory has been set, yet you can see alternating light and dark shaded rows. Each one of these rows in the ListView corresponds to a Cell and each cell has been generated by the default ListView cell factory. When I drag the stage's bottom border to increase the size of the stage, the list view increases in size. When I drag the stage's bottom border to decrease the size of the stage, the list view decreases in size. When the list view increases in size, more rows are visible. Each of the new cells for the larger list view are generated by the cell factory on an as needed basis; i.e. the cells were not created when the app was first run but only created as there was a greater visible area available to the ListView in which the ListView could display more cells.
Now everything is pretty boring so far. Let's add some data, using the following line of code:
listView.setItems(FXCollections.observableArrayList("apple", "orange", "pear"));Now you will see the strings "apple", "orange" and "pear" rendered in the first three cells of the ListView again by using the default cell factory for the ListView. Again this is pretty boring.
What we will do now is add some mutators which will change the observable list backing the list view in response to some user actions:
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.event.*;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.*;
import javafx.stage.Stage;
import java.util.Collections;
import java.util.Comparator;
public class ListViewSample extends Application {
@Override public void start(Stage stage) {
final ListView<String> listView = new ListView<>();
listView.setItems(FXCollections.observableArrayList("apple", "orange", "pear"));
ListViewSorter listViewSorter = new ListViewSorter(listView).invoke();
VBox layout = new VBox(10);
VBox.setVgrow(listView, Priority.ALWAYS);
listView.setMinHeight(0);
layout.getChildren().addAll(
listView,
HBoxBuilder
.create()

guavaCreator(listView),
listViewSorter.getSorter(),
listViewSorter.getReverser()

stage.setScene(new Scene(layout));
stage.show();
private Button guavaCreator(final ListView<String> listView) {
final Button guavatron = new Button("Add Guava");
guavatron.setOnAction(new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent actionEvent) {
listView.getItems().add("guava");
guavatron.setDisable(true);
return guavatron;
public static void main(String[] args) { launch(args); }
private class ListViewSorter {
private final ListView<String> listView;
private Button sorter;
private Button reverser;
public ListViewSorter(ListView<String> listView) {
this.listView = listView;
public Button getSorter() {
return sorter;
public Button getReverser() {
return reverser;
public ListViewSorter invoke() {
sorter = new Button("Sort");
sorter.setOnAction(new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent actionEvent) {
Collections.sort(listView.getItems());
final Comparator<String> REVERSE_SORT = new Comparator<String>() {
@Override public int compare(String s1, String s2) {
return -1 * s1.compareTo(s2);
reverser = new Button("Reverse Sort");
reverser.setOnAction(new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent actionEvent) {
Collections.sort(listView.getItems(), REVERSE_SORT);
return this;
}OK, now we have some extra buttons, the "Add guava" button will create a new item ("guava"), the "Sort" and "Reverse Sort", buttons will change the sort order of the backing list. Now to understand what happens behind the scenes when we use these buttons, let's take a look at the source code for the default list cell factory.
new ListCell() {
@Override public void updateItem(Object item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setText(null);
setGraphic(null);
} else if (item instanceof Node) {
setText(null);
Node currentNode = getGraphic();
Node newNode = (Node) item;
if (currentNode == null || ! currentNode.equals(newNode)) {
setGraphic(newNode);
} else {
setText(item == null ? "null" : item.toString());
setGraphic(null);
};This code is doing one of three things. If the list cell is empty, it sets the text and graphic to null, so you end up with a blank cell (the alternating light and dark grey bars are generated by the ListCell's parent setting differing style classes on alternate cells). If the item is a node, it sets the graphic to the node - this is the mechanism which allow you to place nodes directly in the backing list for the ListView and have the ListView display them OK. Otherwise a toString is called on the item to set the item's text (this is the case which is occurring for our simple example of Strings in the backing list).
Now the important thing to note about the ListCell implementation is that the clever logic of translating the backing item for the cell to a visual representation is occurring in an updateItem call. This updateItem method is invoked by the JavaFX system on the ListCell whenever the backing item for the cell has been invalidated, for example the item has been edited, a new item added, or the items in the list have been reordered.
So when somebody presses, the "Add Guava" button, a new ListCell is not created, instead updateItem is called on an already existing empty cell. This is because when we started the application, there was space for 17 rows, so 17 cells were already created, it is just that most of them were empty because we only had 3 items in the backing list for the ListView.
Now, if we press one of the sort buttons to reorder the backing list, it will cause the existing list cells to become invalidated, and updateItem will be called on each of the cells according to the change permutations in the ObservableList. Note that as each item is updated, a new Labeled display node for the item is not created, instead the setText method is invoked which changes the text for the existing Labeled.
There are a couple of extra cases to understand. Our backing list currently maxes out at 4 items. Let's say we drag the bottom of our stage up so that the available space for the ListView was made really small (e.g. only 2 rows high). In this case, you will two rows (cells) and a scrollbar you can use to scroll up and down. As you scroll up and down it seems that some rows are scrolling off the screen and some are scrolling on the screen. What is actually happening though is that the same two cells are remaining on screen and their contents being continually updated and replaced as backing items come in and out of view. This is the magic of how the ListView is able to achieve it's efficiency when dealing with potentially very large collections or collections where not all of the required data is available on the client at the current time. Instead of creating visual cells for all of the possible items which can be placed in the list, instead the ListView creates cells only for the visible items and updates the content of those cells on an as needed basis. This concept is known in the List Cell creators jargon as a Virtual Flow in a Virtualized control.
OK, so that was a little more interesting, but there have been a lot of words so far, and no custom cell factory. This was partly on purpose - there is lot you can do with the default cell factory without needing to create your own custom cell factory.
But sometimes you do actually want to create your own cell factory when you want fine control over the look or behaviour of the cells.
Let's say you want to show each item in the list with a capitalized friendly name "Apple", "Orange" and "Pear" and an icon - a picture of the corresponding fruit. To do this you would create a cell factory - something that can produce the visual representation of these things from the corresponding data values.
import javafx.application.Application;

listView.setCellFactory(new Callback<ListView<String>, ListCell<String>>() {

return new LabeledIconListCell();
VBox layout = new VBox(10);

private class LabeledIconListCell extends ListCell<String> {
@Override protected void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (item != null) {
String friendlyText = item.toString();
if (item.length() > 0) {
friendlyText = item.substring(0, 1).toUpperCase() + item.substring(1);
setText(friendlyText);
setGraphic(
StackPaneBuilder
.create()
.prefWidth(55)
.children(
new ImageView(
iconMap.get(item)
.build()
} else {
setText("");
setGraphic(null);
}Here what the cell factory has done is to check what value of the backing item for the cell is whenever that item has been updated, and set some customized label text and graphic representation for the cell.
As a minor point, for efficiency, and because there are only a few of them, the required images are loaded and scaled up front so that they don't been to be reloaded every time the cell is updated with a different value (which if the image loading was within the cell's updateItem call could mean that the same image could potentially get loaded multiple times.
My personal take on this is that it is powerful but complicated. Often people will gravitate towards using the complex ListView and TableView APIs when they don't necessarily need all of the functionality and virtualization efficiency capabilities that the virtualized controls offer. In many cases, simple layout mechanisms such VBoxes and Grids can be a better choice. However, if you have a need for the virtualized functions, then it's good to know that things like ListView and TableView are there if you can work out how to use them well in your case.
Also note that JavaFX 2.2+ has numerous convenience methods for creating different kinds of cells which you may be able to use in standard cases to avoid some of the overhead in creating your own, for example the CheckBoxListCell, the ComboBoxListCell and the TextFieldListCell. And there are many more such simplifying higher level abstractions in the DataFX library.
One other point worth observing is that if you have a list of mutatable objects, for example Person objects with a changable last name field, then you need to make the object an Observable object with an invalidation implementation if you want the updateItem call in the cell factory to be invoked automatically whenever the object is mutated.
A cell factory and a cell value factory are different things, but that is probably a topic for a different post.
I realize this was a round about and lengthy explanation - hopefully it served some purpose and helped to explain some of the mysteries of cell factories.

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please! Also, I still don't understand exactly what the benefits are. At the moment it seems a lot of hassle to change a system that's been working perfectly well and that I'm very happy with. I'm not at all sure whether the mac mini (1.66 GHz INtel Core Duo) can be brought up to the relevant spec to run ICloud. Any thoughts?
There are two aspects to iCloud. One is simply getting an account, or migrating a mobileme account to iCloud. The second part is using the various features of iCloud to sync contacts, calendars, use music match or photo sharing, and store iWorks documents.
First to get an iCloud account:
If you have a mobileme account, you can migrate by simply logging onto www.icloud.com (ignore any references to Lion and just click through to complete the migration). If you have OS X Lion or an iOS 5 mobile device, you can create an iCloud account on that device using any valid AppleID.
Once you have an account, you can use JUST the mail account if you wishi - it is a standard IMAP account so you would set it up like any other IMAP email account you have, in whatever client program you use to read email.
To use the OTHER feautes of iCloud, your computers will have to be running OS X Lion (10.7). Your iPhone 3G will never be able to use iCloud as it cannot run iOS 5 (you need a min. of an iPhone 3GS to run iOS 5).
The requirements for OS X Lion are here - http://www.apple.com/macosx/specs.html You need a min. of a Core 2 duo processor so you mini is not capable of running Lion.
So, in your case, the single reasons for iCloud would be if you have a mobileme account, then use the online www.icloud.com to migrate your account so you do not lose your @me.com email address. You can use iCloud email (without using any other iCloud features) by setting it up as IMAP mail with these settings - http://support.apple.com/kb/HT4864
If you want an iCloud account and do NOT already have a mobileme account, you will need to upgrade one machine at least to Lion in order to be able to create an iCloud account. -
What exactly is stored under "OTHER" on your iPhone that you only see when it's connected to iTunes?
Ok, here is how the story have ended for my iPhone 4S.
I took the phone to the genius bar 500-km far from my town. And they told me to wait 20 mins and then they asked what's wrong with the phone. They first thought the battery is dead. But then they changed the battery with a sure-it's-working-battery. But no luck. And told me that "logic board" has gone (why? -no explanation. it just happens).
And then they checked the warranty and noticed that it was expired 29 days ago (the phone was bought from Chicago and I'm in Europe now). Since it's expired, I'm told that it can't be replaced with no cost. I should pay 200 Euros to get a "new" iPhone 4S (you know what is "new" means, refurbished). Or I could buy a brand-new-iPhone5 for 600 Euros.
I'm not rich person and I decided to go with the refurbished one. So, as summary,
- 13 months iPhone is dead. (~500$)
- a refusrbished phone with 3 months of warranty (200 Euro)
- Lost data (I admit that this is my fault not to care about the backup but after phone is dead, I didn't have any way to save data).
I can say that, if you have too much money, yes, Apple products are worth to buy. -
My iPhone became wet at the beach. I put it in rice for 4 days. When I connect to itunes, it says the phone must be restored. It starts and then gives either the error 2001, or 2006. What exactly does this mean, and is it worth getting repaired?
Thank you...http://support.apple.com/kb/TS1275
Water damage isn't covered by warranty, but you could always purchase a refurbished device from Apple. -
"Check Network Connection" - What Exactly Does the TV Check?
Hi everyone
May I please ask, what exactly does the TV check when I choose "check network connection"?
In other words, when I click the "check network connection", what IP address / servers and ports does it communicate to? What checks does it do?
Because my TV cannot establish a network connection via settings, but the browser works perfectly well,
I would like to carry out the same checks of "check network connection" on my PC.
Then, if failed also on my PC, I would turn to my ISP with the results, as I believe it is the one to fault.Assuming you're referring to the Airport icon in the menu bar, 'clear/empty' means Airport is turned off, gray bars means Airport is on but not connected to a network, and black bars means Airport is on and connected to a network. Other possible icon states are solid gray with a little computer inset, meaning you're connected to a computer-to-computer created on the Mac, and gray bars with an exclamation point (10.6 only), meaning connected to a network but not authenticated (e.g. wrong password for an 801.2X corporate/university network).
To your question, it's perfectly possible to be successfully connected to a network (black icon) and unable to access the internet. Situations like that would include the network requiring a proxy server, for which you haven't set up the details on in Network Preferences, or you're connected to an open network that requires you to enter information or agree to terms (e.g. a hotel network, where you need to put in your room number and agree to the charges before you can connect to the internet). -
JMS proxy and XA connection factory
Hi all,
I would like to ask you what is the best practice to adopt about the scenario described below.
A JMS proxy retrieves a message and processes it.
Any error could occurr during processing it and, in case of errors, the JMS proxy error handler publishes the message on ad hoc recovery destination D.
(later another app will check failed messages for fixing & republishing them into ALSB).
In that scenario we have the JMS proxy and the jms business service that, in case of errors, publishes on destination D.
Should the JMS proxy and the business service use both a XA connection factory in order to perform all the above steps in one transaction ?
Otherwise if the business service itself fails publishing on destination D, the message retrieved by the JMS proxy is lost and not re-delivered to the JMS proxy.
Or XA connection factory is not needed and could I use
Routing Options with exactly once or both are needed ?
Thanks
ferpHi all,
I did some tests and follow what I've achieved.
Scenario 1.
- Precondition
-- A JMS proxy with XA factory + Error Destination (MyRecoveryQueue)
-- A business service BS with XA factory that publishes into MyOutboundQueue
-- No "exactly once" routing option used calling BS
-- an error is forced in the pipeline
- Flow
-- proxy retrieves a message and try to publish it using BS
-- an error is forced in the pipeline:
--- transaction is rolled back, message redelivered to proxy
--- the message is posted to the error destination after all the retries failed
Scenario 2.
- Precondition
-- As 1. but no error is forced in the pipeline
-- the MyOutboundQueue destination queue is paused
- Flow
-- proxy retrieves a message and try to publish it using BS
-- BS fails to publish it on MyOutboundQueue (because it is paused)
--- transaction is rolled back, message redelivered to proxy
--- the message is posted to the error destination after all the retries failed
Scenario 2A.
- Precondition
-- As 2. with MyOutboundQueue paused and resumed
- Flow:
-- proxy retrieves a message and try to publish it using BS
-- BS fails to publish it on MyOutboundQueue (because it is paused)
--- transaction is rolled back, message redelivered to proxy
--- before all the retries failed the queue is resumed
--- BS succeeds to publish the message
Scenario 3.
- Precondition
-- A JMS proxy with NO XA factory + Error Destination
-- A business service BS with NO XA factory
-- No "exactly once" routing option used calling BS
-- an error is forced in the pipeline
- Flow
-- proxy retrieves a message and try to publish it using BS
-- an error is forced in the pipeline:
--- transaction is NOT rolled back, message NOT redelivered to proxy
-- so
--- no message delivered to MyOutboundQueue2 destination
--- no message delivered to MyRecoveryQueue2 destination
--- message consumed from MyQueue2 and now is lost!
To publish message into MyRecoveryQueue2 a proxy error handler has to be added and here added explicit publish to MyRecoveryQueue2.
But naturally in that case if in the proxy error handler, the explicit publish fails or any error occurrs no message is delivered to recovery queue.
So if I'm not using an XAFactory the message is auto-acknowledged as soon as it is read and I've to use XA factory if I want the message to be put back in the queue in case of errors and the retry to happen.
So both my proxy service and business service use an XA factory.

Connection pool and Connection factory difference?
Hi,
Can someone clarify the difference between connection pool and connection factory.
I know connection pool is some thing like a pool of database connection manitained at one place so that an application or client can use it when it requires.
Then wat exactly is connection factory..say in 10g we always put a connection factory name in all adapters and acces the data sources like DB ,FTP,AQ ..etc
can someone clarify??
regards,To conserve system resources and to improve the performance of transactional applications, WebLogic allows you to define a pool of client connections (generally database but may be a FTP,FILE etc. as well)
A Connection Factory object encapsulates a set of connection configuration parameters that has been defined by an administrator. A client uses it to create a connection with a service provider (generally JMS).

Problem with transacted JMS connection factory and transaction timeouts
We encountered an interesting problem using transacted JMS connection factories.
An EJB starts a container managed transaction and tries to validate a credit card
before creating some information to a database for the user, in case of success
an SMS is sent to the user via the transacted JMS queue. If the credit card authentications
duration is about the same as the transactions timeout (in this case the default
30 seconds) sometimes the database inserts is committed but the JMS insert is
rollbacked. How can this be?
If the authorization duration is much longer than 30 seconds everything works
fine (both database and JMS inserts rollbacked), the same is true if a rollback
is insured by calling EJBContext.setRollbackOnly(). The problem thus occurs only
if the duration is approximately the same as the transaction timeout, it appears
that the database insert is not timeouted but the JMS insert is. How can this
be if they are both participating in the same transaction.
The JMSConnectionFactory used is a Connection factory with XA-enabled. The result
is the same also with the default "javax.jms.QueueConnectionFactory" and if we
configure our own factory with user transactions enabled.
Any help appreciated!

It should not be.

Make sure that your session is not "transacted". In other words,
the first parameter to createSession() must be false. There is an
unfortunate name re-use here. If a session is "transacted", it
maintains an independent "inner transaction" independent of the
outer transaction. From the above description, it seems unlikely
that your application has this wrong, as you say that
"setRollbackOnly" works - but please check anyway.
Make sure that you are using a true XA capable driver and database
(XA "emulation" may not suffice)
Beyond the above, I do not see what can be going wrong. You
may want to try posting to the transactions and jdbc newsgroups. Note
that JMS is appears to be exhibiting the correct behavior, but the
JDBC operation is not. The JDBC operation appears to have
its timeout independent of the transaction monitor's timeout.

How to access local connection factory created within Foreign Server in OSB

Looks like the JNDI that you created for the ConnectionFactory is not reflected in the server.
Login to WLS Console> Summary of Servers > server_name > View JNDI Tree
Browse to the JNDI tree and see if your JNDI is visible there. If it is not then, please restart the server and recheck.
Once you are able to find it in the JNDI tree, then execute the customization file.
If you have modified the existing JNDI properties (that have a small exclamatory symbol) then any changes to those are not reflected till all the servers in the cluster are restarted.
If it still does not work, then recreate a new Connection with a different name and then retry. It should work then.
Thanks,

I don't get it, whats happening ? why does the adapter care what i am running inside a custom sql step. all it is supposed to do is execute the sql and return the values. Why is it forcing me to rewrite the operation which was working before ?well as always...nothing works like restart of the server. Issue resolved.

What exactly is "other" and why does it take -up so much space?
I'm trying to free up some space on my iPad2, and see "other" is usiong 6.7 gigs.. What exactly is "other"?
Actually "other" is app data, Safari Bookmarks, calendar entries, text messages, notes, Safari History, email messages and things like that - stuff associated with apps - but not the apps themselves or any other media.
Your "other" should be nowhere near 6.7 GB. You had a corrupt sync. You can try restarting, the iPad, rebooting it by holding down on the home and sleep buttons at the same time until the Apple logo appears or unsync all photos and music and then resync all photos and music.
However, many times you need to restore the device to factory settings and then restore from a backup in order to reduce that bloated size. That should probably be no more than 1 GB and more likely between 200 and 750 MB in total size. -
What is an "active connection" to the FMS server?
Hi,
I am wondering exactly what are considered "active connections" to an FMS server?
Is it only the RTMP/RTMFP NetConnections, or do NetStreams also count?
ThanksOnly netConnections. You can't connect a netstream without a netconnection so they don't count on the connection count number.

What exactly does the Radio Beacon Indicate
I have seen cases where the Radio Beacon is black and when it is gray. When it's black you may or may not be able to go through the wireless router to the modem and then to the internet. When it is gray, you cannot really do anything except be in a local mode. However there are instances when the Radio Beacon is black, rather than gray, and you still cannot access the internet. So, what exactly does the activated Radio Beacon Indicate, i.e., that the wireless network is working and the modem is down, or something else entirely ?
Assuming you're referring to the Airport icon in the menu bar, 'clear/empty' means Airport is turned off, gray bars means Airport is on but not connected to a network, and black bars means Airport is on and connected to a network. Other possible icon states are solid gray with a little computer inset, meaning you're connected to a computer-to-computer created on the Mac, and gray bars with an exclamation point (10.6 only), meaning connected to a network but not authenticated (e.g. wrong password for an 801.2X corporate/university network).
To your question, it's perfectly possible to be successfully connected to a network (black icon) and unable to access the internet. Situations like that would include the network requiring a proxy server, for which you haven't set up the details on in Network Preferences, or you're connected to an open network that requires you to enter information or agree to terms (e.g. a hotel network, where you need to put in your room number and agree to the charges before you can connect to the internet). -
What exactly does the Work Offline option do in a shared review hosted on an internal server?
Hi,
What exactly does the Work Offline option do in a shared review hosted on an internal server?
I *think* it simply disconnects you from the review server. I'm not sure why one would want to do this.
I'm trying to recommend an offline workflow for reviewers who may not be able to access a shared review hosted on our internal server (for example, while traveling). These reviewers would like to be able to comment on an offline version of the review PDF and then publish their comments when they can again connect to the Internet/internal server.
It doesn't seem like "Work Offline" is the right fit for this scenario. Instead, should reviewers save a local copy to their hard drive, comment on it, and then, when reconnected to the Internet, open the local copy, click Reconnect to Server, and then click Publish Comments?Thanks, Dave. So for my hypothetical traveling reviewer, it would be reasonable to suggest the following steps for an offline workflow?
1. Connect to the shared review.
2. Choose Work Offline from the Server Status menu.
3. Close and save the review PDF locally.
4. Comment while traveling.
5. When back in the office, open the local copy of the review PDF.
6. Click Reconnect to Server.
7. Click Publish Comments.
