Unit Test using persistence bad unit code
In the middle of learning Maven, I created a simple application in which I use JPA (Java Persistence 1.0.2) with EclipseLink implementation (2.0.2).Note: This is a managed Application environment. So I manually order the EntityManager lifecycle.
The persistence.xml file used by the main source code is different from one that uses the unit test code. Main code uses an Oracle DB and test code uses a Derby in memory.
Running the unit tests has been updated the Oracle DB (!) and I eventually managed to fix this in the XML files using two units of persistence.
However, I do not understand why that corrects the problem. I manually create and arrest those responsible for the entity, and they do not work at the same time. I'm sure that Maven (or how I've implemented) is not waste resources (XML files). In fact, looking at Maven debug output, I can see that it uses the XML file for the unit tests.
Could someone enlighten me please?
You have two persistence.xml files on your classpath? If so and they contain the same name for their respective persistence units, you should receive a warning or error as they must have unique names. There is no way of knowing which you want to access otherwise.
Best regards

Store changed from the United Kingdom to China the other day using my old zip code. Now can not return to the United Kingdom. Payment type is NONE, but get requests in billing add card details that they are not everything. Postal code is changed back to UK. Phone is iOS 4 s 9.2.1. Any ideas how to get back?
Hi Sandyback,
Thank you for your participation in the communities of Support from Apple.
I see that you have changed the country associated with your Apple (iTunes Store account) ID, and now ask you to provide a method of payment. This happens when changing the country on an existing Apple ID, according to why I can't select None when I change my Apple ID payment information?
If you have changed your country or region
When you change the country or the region of an Apple ID, you must provide a payment method and update your billing options. If you want to delete your payment method after you change the country or region, you can change your payment information to none.
You will not be able to see or select the no payment option for one of these reasons. If you don't want to use a credit card, you can use another form of payment, for example, a gift card.
Sincerely.

The unnecessary use of synchronize in code example in the Dev Guide
I ask this question with some trepidation, I'm sure someone out there will be able to explain it and then I'll feel really stupid asking. But that's...
Using a HTTP connection code sample in the developer's Guide (I checked 4.3 and 4.5, and it's the same in these two levels), use synchronized in two places that I don't understand.
(1) getUrl() - Code follows
/**
* Retrieve the URL. The synchronized keyword ensures that one
* thread at a time can call this method on a ConnectionThread object.
*/
public synchronized String getUrl() {}
Return _theUrl;
}I understand the comment, and it is sometimes useful force methods you want to synchronize. But not this method in vessel closed. If anything, there are more cases of use of this mechanism for the recovery method in this code.
(2) around of the fetch block - following Code:
/ * Make sure that pull requests are not missed
* While the received data is processed.
*/
{Synchronized (this)}
Open the connectionWhen I see a synchronization block like that, I guess it's a little shared code that can be executed by multiple threads, which this clearly isn't. So why is it synchronized?
In fact, I think that 'design' is a testament to this example may be imperfect. I think it would be better to have a new Thread for each connection, or have a queue (synchronized) URL addressing.
As evidenced by another thread on this forum, the developers make these samples as Gospel and try to use them. So if this is wrong, perhaps we could fix. But maybe it just me being a lumberjack full. Wouldn't be the first time... And won't be the last!
It seems that this example has been designed with a base defense to the following (if no synchronization) scenario:
Event thread request _start = true.
Threaded starts the connection.
Event thread again pray _start = true.
Threaded end connection, defines _start = false.
Net result: the second event thread request is not met.
That being said, the guys are right: this design is mediocre at best. In the scenario above, the second request of event thread is blocked while the thread of the connection ends... and as everyone knows at this point, blocking the event thread usually leads to a world of pain. There are certainly better approaches that can be used here, and probably the easiest way to this problem is just to have the best control flow, such as not allowing not a new connection request while one is already underway. Certainly the synchronization adds excessive complexity to this problem and distracts from what the sample is trying to demonstrate: a simple HTTP connection.
For this example, and the extraction, I will recommend to the authors that both be reviewed and be a structure such that these samples are as simple as possible. Thanks to Peter marchywka for their suggestions. Comments like yours, it's how we identify areas for improvement.

Nedopil part of sequence to run once in test USE
Hello
I use 1 file encoding to run tests on a number of different types of products.
Right now I use a message box to the user to select the product under test and based on the return of the message box, I select the correct limits to laod with the shipper of the property.
My problem is that I don't want to see this message every time a device box is test using test DUT. (only on the forst to run)
Can someone please adivse the best approach to deal with this case.
PS: I want to stay away from change my IO, I want to enter in the case of having customized OIs for different test sequences.
Kind regards

Hello
To try to make my suggestion:
1. open your movie file in the editor of Teststand.
2 Select the pull-down Edit menu, select the sequence Callbacks... file option.
This should display a new dialog box display the available callbacks associated with the process in use template.
3. in the new dialog box select/highlite the recall of PreUUTLoop , and select Add.
This should add a new subsequence to your sequence called PreUUTLoop file.
Close the new dialog box.
4. open / select the new PreUUTLoop under sequence in your movie file.
Insert a new type of Message Popup enter group main step, add a simple text just to try the idea.
5. run your movie file. The simple text you entered to appear as a Message Popup dialogue
box, just once, before entering the test loop.
6. If it works for you, replace step Message Popup with your steps that get user information.
Kind regards

Access using time to time code
I want to use the functionality of code pass occasionally. If I put the code to access and use it, I'll be able to disable the security option settings and the use of the phone without entering a code. This option is on my ipad but not sure about the g. motorcycle want to set an access code and then continue to use it.
If you set a pin code, you can disable it later. Settings-> Security-> screen lock. Come back you here after the setting, put your pin code back in and then choose 'none' as an option.
But if ever you forgot your PIN, until you turn it off, reset is the only way back in.

Hello
This means that the computer cannot connect to the router.
Try this process.
Check the Device Manager for the wireless card valid entry.
http://www.ezlan.NET/Win7/net_dm.jpg
If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.
Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.
http://www.ezlan.NET/Win7/net_connection_tcp.jpg
Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.
Make sure you firewall No. preventing / blocks wireless components to join the network.
Stack TCP/IP work should look like.
Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.
http://www.ezlan.NET/Win7/status-NIC.jpg
Description is the data of the card making.
The physical address is MAC of the card number.
The xx must be a number between 0 and 255 (all xx even number).
YY should be between 0 and 255
ZZ should be between 0 and 255 (zz all the same number.)
The date of the lease must be valid at the present time.
* Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.
* Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.
---------------------------------------------------
Above everything is OK, you must be able to connect to the router. A window that says connected does not mean that you are really connected. Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see. If it is not connected in the log to router from any computer that can connect to the router wirelessly with a wire, disable wireless security, (make sure that the wireless SSID broadcast) is on and try to connect with no. wireless security.
--------------------------------------------------
I really checked and configured every thing and it doesn't work.
Software firewall application that is not configured to allow local traffic (between the computer and the router is also a possible problem.
some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic. If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .Jack-MVP Windows Networking. WWW.EZLAN.NET
