What happened when using non-TX datasource connection in a Transaction?
Hi,
I try to update a timestamp table in a transactional EJB method invocation.
The table is in the same db where the entity bean stores. I get the
connection via DataSource (non-transactional), and issue the sql statement,
and then close the connection.
My question is: is my update part of the EJB transaction? If yes, how do
I manage to get the timestamp update out of the scope of the transaction
since I just want to timestamp no matter wether the EJB transactional method
invokcation succeed or fails. Do I need to explicitly suspend and resume
the transaction?
Thanks!

and will succeed or fail at the time you do it, regardless of the eventual
fate of the EJB transaction.

What happens when there's no internet connection?
The only reference I can find to this is here
http://forums.adobe.com/message/4539999#4539999
But the thread is old and appears to have been shut down with no answer to the fundamental question.
Bottom line is that there are a 1000 valid reasons you may not have a connection and a 100 reasons that situation may not change for weeks.
So what happens, does CC just shut down?
RobHi Rob,
I copied this from the Creative Cloud FAQ - http://www.adobe.com/products/creativecloud/faq.html
Do I need ongoing Internet access to use my Adobe® Creative Cloud™ desktop applications?
No. Your Creative Cloud desktop applications (such as Adobe® Photoshop® and Illustrator®) are installed directly on your computer, so you won't need an ongoing Internet connection to use them on a daily basis.
An Internet connection is required the first time you install and license your desktop apps, but you can use the apps in offline mode with a valid software license. The desktop apps will attempt to validate your software licenses every 30 days.
For annual members, you can use the apps for up to 99 days in offline mode. Month-to-month members can use the software for up to 30 days in offline mode.
So after 30 days it will attempt to connect, and give you a notification if it is unable to do but the software will continue to work.
Hope that helps,

What happen when we connect Two PC with IP from Same subnets
Scenario 2nd : What happen when we connect Two PC with IP from Same subnets. PC1 -192.168.10.1/24 PC2 - 192.168.10.2 on a two different L2 Switch on different vlans which are connected via a LAN cable.
All ports are access ports
Interview Question : No More Info.
Pc1<SwA>------<SwB>PC2
Q.1 Will they communicate If yes what will be packet/frame flow.
Q.2 If not where will be the packet/frame drop. ? Why.
I need step by step if possible plz how the packet moves , vlan taggings n all internal works that happens behind .. plz
thnx in advnce ....Hi Abhishesk,
The PCs should communicate each othet.
Since there is no trunk port involved, there is not tagging involved.
Since both the PCs are into the same subnet. PC1 will not need default gateway for the communication with PC2. So PC1 will start with sending ARP request for PC2 MAC address.
Since all the ports in SW1 are in same VLAN, the ARP should reach all ports including the switchport where SW2 is connected to.
Sw2 has got a complete different access port on ALL the switchports. Sw2 will receive the ARP from Sw1. Remember that there is no tagging for the frame. Hence Sw2 will again send the ARP packet to all the ports which belong to same VLAN wherein the packet is received. ie, Sw2 will send the ARP packet to all the ports in Sw2. PC2 will also get the the ARP.
The ARP reply will make it way back using the same logic.
Now both the PCs can start the actual packet exchange. -
I want to change my Apple ID because I have a new email address, but what happens when someone tries to facetime me using my old Apple ID? Will they still be able to contact me on facetime using my old Apple ID?
Not if you change the ID. You would need to give them the new address.

What happens when I restore data to a non-factory set iPhone?
Okay, another iCloud question. What I did was basically delete a game, start a new one, and now I want my old game back (saved to ICloud). What happens when I restore full data to a non-factory set iPhone? Will it overwrite current data? Will it delete everything? I just want to know, I'm such an iOS noob. :-/
A restore is all or nothing.
If a backup is restored to the device, ALL data currently on the device is wiped and replaced with the data from the backup.
Restoring a backup to get one saved game back seems rather extreme and silly. -
if I have two laptops connected to a single wireless hard drive (i.e. Time Capsule), what happens when one laptop wants to go on a trip and the other one needs to stay home? I'm afraid I know the answer, but I'm hoping Apple has a great solution to my problem.
What if this little piggy goes to market but this little piggy stays home?
The computer on a trip will do snapshot backups on the hard drive that will then be incorporated into the Time Machine backup once you get it back home. See
OS X Lion- About Time Machine's "local snapshots" on portable Macs
Open the Terminal in the Utilities folder and enter or paste the appropriate command line. Press RETURN and enter your admin password when prompted. It will not be echoed.
To turn them ON: sudo tmutil enablelocal
To turn them OFF: sudo tmutil disablelocal
Note that turning them OFF will also delete all existing snapshots. -
What happens when you attempt to download a digital copy, but it doesn't upload in iTunes, and you're not allowed to use the code again?
Thanks for your reply, but you might have misunderstood it a bit. I'm NOT trying to buy a movie. ****, I'm not even in the actual Apple Store, when this happens I'm in the library not the Store part of iTunes.
To clarify - I have purchased a physical copy of a movie which came with another physical copy which contains the digital copy. The digital copy is on the DVD, all I need is just to transfer this file to my iPod Touch, for example, I'm not trying to download it from the store or repurchase it and it's not any gift code that I've received, the digital copy is on the disc. This is the first time ever that I've purchased something on a disc and I'm not allowed to access it because the disc hasn't been purchased within my country.
So again - I'm not attempting any purchase or download any purchased digital copy - it's on a DVD I own physically so... why is even the region of my Store relevant, the code I enter is (as I assume) just supposed to check if it's a legal genuine copy (which it is, as I've said - there are 6 discs in the pack: 3 movies on 3 Blu-rays and 3 DVD containing these digital copies of them). If I own it, I think that's proof enough that I have the right to use it. I just don't get it. I fully agree with you and understand your point if there was any purchase going on here, but it's not, it's just - I put a disc into my computer and I can't access it -
What about when using the "Time Capsule" HD as the external disk, especially when it is connected by ethernet cable? I'm having trouble getting it to work at all. Don't need it to work as anything else, other than a ethernet connected Time Machine backup. Already have a wireless network that works fine so no need to mess with it. We get the internet via cable company and their modem is upstairs and the Time Capsule is downstairs in the basement. The latest error message was about it could not backup as it was already in use (should have written it down before clicking OK and moving on.
See if this helps...

Server: JBoss EAP 6.2.0
Client: JDK 1.7.0_51 x64
JAX-WS: RI 2.2.8 ( via -Djava.endorsed.dirs )
I am getting a java.lang.NullPointerException when calling the operation on the WS endpoint from the client when using non-anonymous replyTo address.
I have simplified the scenario into a small test case that hopefully others can replicate. Since the exception is happening on the client instead of the server, I would think that the container used is irrelevant, but I have specified it nonetheless.

} catch( Exception ex ) {
ex.printStackTrace();
} finally {
Thread.sleep(10000);
endpoint.stop();
System.exit(0);
4b) ClientHandler.java - Used to set the wsa ReplyTo address and FaultTo address when sending SOAP request from client to server
package test.wsclient;
import java.util.Set;

import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPHeader;
import javax.xml.ws.handler.MessageContext;

/* extract the generated MessageID */
String messageID = getMessageID(header);

/* change ReplyTo address */
setAnAddress(header, "ReplyTo", (String) context.get("ReplyTo"));
setAnAddress(header, "FaultTo", (String) context.get("FaultTo"));
} catch (Exception ex) {
throw new RuntimeException(ex);
return true;
4c) CallbackSEI.java - endpoint on the client for server to send the SOAP response back to the client
package test.wsclient;
import javax.annotation.Resource;
import javax.jws.Oneway;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.ws.Action;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.soap.Addressing;
@WebService
@Addressing
//@HandlerChain(file = "/handler-chain.xml")
public class CallbackSEI {
@Resource
private WebServiceContext context;
* If there is no namespace specified in the method below, then the CallbackSEI needs to be in the same package as the
* WS endpoint.
@Oneway
@Action(input="http://services.nowhere.org/RandomTest/nextRandomResponse")
@RequestWrapper(localName="nextRandomResponse", targetNamespace="http://services.nowhere.org/")
public void handleNotification(@WebParam(name="return")long random) {
System.out.println("Asynch response received");
System.out.println( random );
//System.out.println("This response relates to the message ID: "+ getMessageID());
In summary:
Server is listening on port 8080
Client will listen in port 8082 for the callback from the server for the SOAP response
Now when I run the client, I see that the proper behaviour as far as ws-addressing is concerned. That is:
client -- SOAP request ( on port 8080 ) --> server
client <-- HTTP 202 ( empty HTTP body ) --- server
client <-- SOAP response ( on port 8082 ) --- server
All well and good, except that I am getting a NullPointerException on the client side when I call the operation.
With debugging of the SOAP request and responses, I get the following output:

Any ideas ?I think I have found when I get this error and probably I have found a bug. I will appreciate if someone can confirm this.
In my BPEL project setup, my BPEL process's wsdl file imports another wsdl from different namespace. Here is sample snippet -
<wsdl:definitions targetNamespace="http://namespace/1">
<wsdl:import namespace="http://namespace/2" location="resources/another.wsdl"/>
<plnk:partnerLinkType....../>
</wsdl:definitions>
Please let me know. I checked the bundled samples with Oracle BPEL PM and did not find any similar case where process wsdl imports another wsdl.
Thank you.

Lost my iPod, remotely locked it through iCloud. What happens when the battery goes out?
Hello!
I lost my Ipod, but managed to locate and lock it remotely through Find my iPod and iCloud. It was located once, but hasn't been located again in the last four days. I think the battery may have run out. What happens when the battery is charged and the iPod turned back on? Does the lock and everything else that can be controlled with Find my iPod still apply?
Thank you!Yes, because when you remotely lock the iPod via Find my iPod, the lock code is set as the lock code that you would use to unlock the iPod if you used a passcode normally. As long as the iPod is still connected to your Apple ID, Find my iPod should work as log as the iPod is connected to wifi.

What happens when you AirDrop from Mac to iPhone and click Cancel?
I have a Late 2013 27" iMac running OS X Yosemite 10.10 and an iPhone 6 Plus running iOS 8.0.2.
I can take a PDF on my iMac, drag it to my iPhone in the AirDrop section of Finder, and it transfer to my iPhone just fine. Once it's finished transferring, a popup shows on my iPhone asking me what app I want to open the PDF in, which is great. At the bottom of that popup is a "Cancel" option. My question is, what happens when you tap "Cancel" instead of one of the apps? Is the file still somewhere on the iPhone? Or does it get deleted?Connecting to a new computer or iTunes will always erase the device first. Back up manually before by right clicking on the iPod in the device list and choosing "backup". A manual backup does not include the sync process. You can use this backup to restore from after your iPod got wiped during the first sync.
Transfer your purchases the same way and make sure to have at least one contact and event listed on your Mac, to be able to merge data.
See also iTunes: About iOS backups to get more info about the content of a backup, and How to back up your data and set up as a new device , if you want to know more about saving info from the iPod before setting it up in iTunes. -
TS1398 what happens when I reset network settings?
what happens when I reset network settings on I Phone 5?
Hi Jim Blau1!
The answer to your question can be found in this article that you have linked, about troubleshooting iOS Wi-Fi network connections:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/ts1398
Specifically, I believe this statement will answer your question:
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings including: previously connected Wi-Fi networks and passwords, recently used Bluetooth accessories, VPN and APN settings.
Thanks for being a part of the Apple Support Communities!

I recently downloaded Parallels 9 to my imack so I could install Windows 7 Home Premiumwith no problem and everthing is working fine, and I was thinking of Migrating the 2 2 and was wondering what benefits there would be and what happens when I do.
Windows 7 will peer down through the VM and remember what hardware the VM is installed on. Migrate the VM to different Mac hardware, and on first boot, Windows 7 will advise you that you are not using genuine Microsoft Windows. It will then treat you as though it believes you misappropriated it.
