Is there any tutorial for annotations

I downloaded the spec but it is a bit too technical for me. I need something for the dummies, like the generics tutorial..

Sorry for taking a bit long. Yes that it the tutorial I am referring to.

Is there any tutorial for jms development with jdeveloper out there ?

Hi
Thank you for reading my post
is there any tutorial which show us how to use jdeveloper +oc4j for JMS stuff ?
I mean an end 2 end tutorial to build mdb+jms resources in oc4j + client
it will be far better if the tutorial shows how we can use jdeveloper features for this task (if it provide any wizard...)

This is an example of a client:
public String listeningJMS (Context context) throws Exception
String topicName = "jms/demoTopic";
String topicConnectionFactoryName = "jms/TopicConnectionFactory";
TopicConnectionFactory topicConnectionFactory = null;
TopicConnection topicConnection = null;
TopicSession topicSession = null;
Topic topic = null;
TopicSubscriber topicSubscriber = null;
TextMessage message = null;
String fileName = null;
* Look up connection factory and topic. If either does
* not exist, exit.
try
topicConnectionFactory = (TopicConnectionFactory)
context.lookup(topicConnectionFactoryName);
topic = (Topic) context.lookup(topicName);
* Create connection.
* Create session from connection; false means session is
* not transacted.
* Create subscriber.
* Register message listener (TextListener).
* Receive text messages from topic.
* When all messages have been received, enter Q to quit.
* Close connection.
topicConnection =
topicConnectionFactory.createTopicConnection();
topicSession =
topicConnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
topicSubscriber =
topicSession.createSubscriber(topic);
topicConnection.start();
System.out.println("Receiving: ");
TextMessage msg = (TextMessage) topicSubscriber.receive();
String xmlString =msg.getText();
topicConnection.close();
System.err.println("Received: "+xmlString);
fileName = this.getFileName(msg.getText());
} catch (Exception e) {
throw e;
} finally {
if (topicConnection != null) {
try {
topicConnection.close();
} catch (JMSException e) {throw e;}
return fileName;
public static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
// Standalone OC4J connection details
env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.rmi.RMIInitialContextFactory" );
env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
env.put( Context.SECURITY_CREDENTIALS, "welcome1" );
env.put(Context.PROVIDER_URL, "ormi://localhost:12401");

Is there any tutorial for SAP Java Backend Development?

Hi everyone,
I am following the "How To - Part 1: Build an Agentry based app from scratch connecting to a SAP ERP back-end" to learn Agentry by myself.
There are some Java code when creating the Steplet, StepHandler and Bapi that I dont understand. I would like to know if there is any document or tutorial to learn how to write such Java code. I already know the Agentry stuffs like fetch, step, etc.
For example, why do we need the processResult or setParameter method? Why do we need JCO.Table? Where is the table "ET_FLT_SCHEDULE"
public class FlightScheduleBapi extends AbstractFetchBAPI{
public User user = null;
public FlightScheduleBapi(User u, GregorianCalendar lu) throws Exception {
super(u, lu);
user = (User) u;
@Override
public ArrayList<SAPObject> processResults() throws Exception {
ArrayList<SAPObject> spfliTab = new ArrayList<SAPObject>();
JCO.Table _sTab = _tables.getTable("ET_FLT_SCHEDULE");
int rows = _sTab.getNumRows();
for(int i = 0; i<rows; i++)
_sTab.setRow(i);
FlightSchedule spfliLine = new FlightSchedule(_sTab);
spfliTab.add(spfliLine);
return spfliTab;
@Override
public void setParameters(SAPObject obj) throws Exception {
super.setParameters(obj);
try {
} catch (Exception e) {
user.rethrowException(e, true);
Thank you very much.

Anyone can help me out of this?
I am looking for AbstractFetchBAPI but there is no information about it.
I found JCO Client Connection and JCO getTable to access SAP tables. Can I use this way in Agentry App?
Thanks.

Is there any tutorial for an extension that just changes a variable in the about:config?

Hi all,
I am trying to create my first firefox extension, which will simply change the value of one of the about:config variables. I looked all over for tutorials that could help me, of course, but I found none that covers that specific matter (changing a variable of the about:config). Do you know any?
Thanks in advance!

Hi Maudluna,
I understand you would like to sign out your Apple ID from an iPad. You can do this easily by following the steps in the article below. I have also linked to an article about Family Sharing which can help you create and manage multiple accounts:
iOS: Sign in with a different Apple ID in the iTunes Store, App Store, and iBooks Store - Apple Support
Start or join a family group using Family Sharing - Apple Support
Family Sharing makes it easy for up to six people in your family to share each other’s iTunes, iBooks, and App Store purchases without sharing accounts. Pay for family purchases with the same credit card and approve kids’ spending right from a parent’s device. And share photos, a family calendar, and more to help keep everyone connected.
Thank you for contributing to Apple Support Communities.
Take care,

Any tutorial for building adapters and routing services for JBI container ?

Hi
Thank you for reading my post
is there any tutorial for Sun JBI container ?
I want to know how i can build/deploy JBI components like adapters and routing service for Sun JBI container .
another question is that , is it based on OpenESB ?
thanks

You can find a white paper on writing a JBI service engine here:
http://java.sun.com/integration/reference/techart/DevelopingAServiceEngineComponent-1-2.pdf
Also, there is a lot of information on JBI and Open ESB here:
http://java.sun.com/integration/
You ask if the Sun JBI container is based on Open ESB - it's actually the other way around: Open ESB is based on the Sun JBI container. The JBI container is a JSR208-compliant implementation, and Open ESB builds upon that implementation to add full ESB capabilities.
hope this helps -

Are there any shortcuts for creating Value Object Classes?

Hi,
I'm using a Remote Object to connect to my server
(pyAMF/Django). I'm getting stuck with the creation of Value Object
Classes. It doesn't seem very DRY to have a class on my server
representing the data model and then have to recreate that class
and all its properties in my Flex app.
Are there any shortcuts for creating client side VOs from
server side data?
I was thinking about declaring an empty VO class in Flex, and
then dynamically assigning/casting my Proxy object to that class.
It seems like that approach may cause problems for the Flex
compiler though.
Any hints?
Thanks!

One thing that has helped me in that area is a free tool from
Farata Systems called
DTO2Fx. If you're using Java and Eclipse, it's a great time saver.
You simply install a (very lightweight) Eclipse plugin, add a
single annotation to your Java VO classes, and it automatically
generates your Flex VOs. It even creates a base and extended
version of each VO on the AS3 side so you can add code to the
extended VO without fear of having your changes overwritten when it
regenerates your Flex VOs.

Is there any way for a basemap to be manipulated from the client side?

Hello,
Essentially, we have a basemap (+basemap A+) that contains boundary geography (i.e., county, tract, block boundaries) and we have a theme (+theme A+) that contains housing unit points.
The idea is that theme A will be a layer that the user will be able to switch on/off. We know how to do this, but the problem comes in where performance is concerned.
Previously, theme A was actually included in basemap A, and performance was not an issue, but the problem then was that the user was not able to turn that layer on/off.
Also I have done everything I know in terms of caching as well as using the mapviewer API
(e.g.,
test_theme.setClickable(false);
test_theme.enableInfoWindow(false);
test_theme.enableInfoTip(false);
test_theme.enableLabels(false);
test_theme.enableAutoWholeImage(true);
test_theme.setMinVisibleZoomLevel(5);),
but rendering the theme on the client side is still way too slow (even at zoom level 5).
So, my question boils down to this. Is there any way for a basemap to be manipulated by a user? I.e., Is there a way for a user to pass parameters to a basemap, essentially telling it which themes to turn on/off?
I know you can specify which zoom level the basemap's themes are visible, but again, we want the user to be able to have control of when a certain theme is shown or not.
Thank you for any help you can provide,
John

What you may try is to replicate your base map but take the point theme out of its definition. Then create a second tile layer for the new base map. You can add both tile layers to the client (but set only one of them to be visible). Then simply switch the tile layers' visibility on/off based on user turning on/off the point theme. The built-in Oracle Maps tutorial #22 (Multiple Base maps) has some sample code you might be able to re-use.

My ipod nano 6th gen fell out of my pockey and the screen cracked badly, is there any coverage for this under warranty? I just bought it a month ago. If not what are the options for getting it fixed

My ipod nano 6th gen fell out of my pocket and the screen cracked badly, is there any coverage for this under warranty? I just bought it a month ago. If not what are the options for getting it fixed? It is pretty frustrating, it fell from about 3 feet out of my pocket and now looks like it was beaten by a hammer.

Should I just ask for my money back??? If it is a simple repair do I just literally push the disc in, push the power button and hold down the C button?
That's where I would begin, too, with
Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.TStatus of HDD at the bottom of right panel, and report if it saysanything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need touse autility like TechTool Pro,Drive Geniusor DiskWarrior
First we need to determine if the issue you are experiencing with the computer is software or hardware based. Once we have gotten things sorted out there should be time enough to make you decision about keeping or returning it.

I have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

i have an iphone and an ipad (which are connected by the same apple id) i broke the phone and sold it but i didnt get to factory reset it because it was broken, is there any way for me to wipe my iphone from my ipad?

Try this:
Open the "Find my iPhone" app on your iPad, fill in your AppleID and password at the start up screen, and you should see a list of all your devices and their current location, if connected to a Wi-Fi or mobile data network. Devices not connected will be shown as "offline". But you can still trap on the icon and hit "erase iPhone" in the right hand window.
If your iPhone is not listed, you did not activate this feature during the setup of the phone and it can't be erased remotely.
If the phone is listed, even as offline, tap on "erase" to send the erase command. The next time your device will be connected to any kind of network, the content will be erased.
