EJBHomeFactory and caller identity

Currently I am passing the user identity when I create the InitialContext, and
I access this user information during some processing in the EJB ( Entity/StatelessSession
If I were to cache Home references, then who is the caller when a home.create()
is invoked? Is there an implicit caller? ( doesn't sound right ) or is it the
caller who had originally created this home reference?
How can I associate a particular user with a home reference?
Thx, Sonali.

Thanks. What you mention sounds right. However, how does the method invocation
know who the user is? If the client is outside weblogic and he asks a factory
to give him a home reference, and then he invokes home.find() or home.create(),
then where is his identity being passed in?
Is there some standard that mandates this behaviour? I did not see anything in
the ejb spec.

Hi,
If I were to cache Home references, then who is the caller when a home.create()
is invoked? Is there an implicit caller? ( doesn't sound right ) oris
it the
caller who had originally created this home reference? The create method will be called with the context of the current user
not the
context of the user who had originally created this home reference .

EJBException::No valid security context for the caller identity

Hi,
I was working with EJB and i had a basic doubt in security propogation from the web tier to EJB tier.
I deployed an EJB on JBOSS app server and in that bean i was trying to get the caller principal object from the EJBContext and i was printing the name of the principal.
System.out.println(ctx.getCallerPrincipal().getName());
then i created ordinary EJB client which is a java class and when i invoked the business method i was getting the below error
Exception in thread "main" javax.ejb.EJBException: java.lang.IllegalStateException: No valid security context for the caller identity
at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:63)
at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:83)
at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:191)
This error sounds meaningful but how will i set the security context from the java class. If it can be done then is this the same way that the security principal propogates from web tier to EJB tier.
Thanks,

Evening and weeknd packages and caller display

My BT contract is up in a few months. Currently I'm using the line rental saver option and have a 2 year old deal which is:
40GB broadband
Evening and weekend calls
Anytime calls add-on
and the £1.78 a month charge for caller display (after BT removed their BT privacy package)
Now, looking up the new packages I notice that evening and weekend calls are no longer offered, with weekend only and anytime the only options. Is this correct?
Also, is there any way of having the caller display option without having to pay £2 a month?

When considering renewal, be aware that BT have a nasty habit of hiking up the prices of obsolete bundles. The Tarriff Guide has a bewildering array of obsolete tarriffs, all at different prices http://www.productsandservices.bt.com/consumer/assets/downloads/BT_PhoneTariff_Residential.pdf
A broadband package and a calls package may be a completely different price to a combined broadband and calls package. Sometimes two apparently identical packages can have completely different prices, just because they have different names.

Someone spoofed my number and called thousands of ...

I've now gotten several hundred voicemails of people calling me back, even though I changed my outgoing voicemail to explain that I didn't call and my number was spoofed. How can I track down whoever spoofed my number or get the calls back and voicemails to stop? I've used this number for years so don't want to change it. Thanks!

Sorry to hear about you being affected by such a bad case of (caller) identity theft. Unfortunately Skype does not have any influence over your caller id being spoofed via third party systems. I recommend following the last step from this article: https://support.skype.com/en/faq/FA34447/what-should-i-do-if-i-see-abusive-behavior-on-skype
Given above and as bad as it is, I think it's safe to say that unfortunately your Skype number is now "burned" and there's little hope you can use it the same way you used it before again. Probably the best is reaching out to Skype customer service explain what happened and ask for cancellation of your subscription and a refund so you can purchase a different number.
I also understand that your Skype account is swamped in voicemails. Probably the best to combat this is temporarily disabling your voicemail via your Skype wrb account page at www.skype.com/go/myaccount to prevent new messages from being added. Then sign in to Skyp for Windows desktop and delete those voice messages.

Caller identity?????

good day
newbie on the BB using the BB Curve 8520 since 09.01.2010
is there any body who can tell me how to setup my caller identity - meaning to see who is calling me. all incoming calls are shown as unknown and i have correctly completed my contacts.
also how to increase the volume on incoming sms an email notifications.
please this is frustrating
thanks

Often, Caller ID is a 'feature' that your wireless company enables at their end - and depending on your Plan, is included or is available at an additional charge. If you think you should have it and its not showing up, call their Support to ensure its set up.
As for volume of various notifications, look on your Blackberry for Options > Profiles (Ring Tones) > Normal (Active) and then scroll to the applicable service and click. There you will be able to set the tone, vibe and volume. Once done, click the Back arrow > Save and then you should be good to go. Note there are individual settings to 'Out of Holster' and 'In Holster' - be sure to set both.
Hope this helps!

Iphone 5s bad réception 3g and 4g signal and call

Hi, my iphone 5s very bad network reception in my home and my calls is very bad quality same outdoor.
Ios 7.0.2.
Sim card ok
All settings by defaut.

Hello there Kevkev5s,
It sounds like your call quality and reception are low both inside, and outside. I want to recommend a couple of articles to help troubleshoot the cellular connection quality. The first is named:
iPhone: Receiver and call audio quality issues
http://support.apple.com/kb/ts5196
Increase the volume during the call.
Make sure nothing is blocking the receiver. If you're using a protective case or display film, remove it and try again.
Make sure nothing is plugged into the headphone jack or the dock connector.
Check the receiver opening to see if it is clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush.
Try another location with better signal. If the audio issue happens only when on a call, it could be due to the location.
If the iPhone is paired with a Bluetooth headset or a car kit, try turning off Bluetooth on your device. Learn more about troubleshooting Bluetooth connections.
Restart the iPhone.
Make sure your device is up to date.
If the issue is not resolved after restoring the iPhone software, contact Apple Support.
If the issue is not resolved, or the above does not help I would next try the troubleshooting in this article named:
iPhone: Troubleshooting issues making or receiving calls
http://support.apple.com/kb/TS3406
Thank you for using Apple Support Communities.
All the best,
Sterling

I deleted a contact out of my iPhone 4S but when I go to send a message the contact appears although that individual is no longer in my address book. I deleted all text and call history pertaining to the deleted contact but still shows up.

Dropped calls and "Call failed" on edge

My experience has been the opposite from others on the forum with the new 2.0.2 software. I can get 3G in town and I can place and receive calls just fine. At home, I only have an edge connection with usually 2-3 bars. 9 out of 10 calls I try to make from home fail. I get the three beeps and "Call failed" message on the screen. Usually it is a split second after I hit the call button. It's not even trying to make the call. I have restored it, restarted, etc. and it still happens! I cannot make a phone call at all. This is my business phone, and it is affecting my response to clients. Anyone have any suggestions? I will probably go to the genius bar tomorrow, but if I don't have to go through the hassle, I won't.

tigerarch,
Does this happen in all locations, or just your home?
What does the AT&T coverage map show for your home?
I live in a moderate area, and AT&T's disclaimer on the coverage map says that Good and Moderate may not have in building coverage. Not only does my iPhone sometimes not pick up a signal or complete calls, the same applies to other AT&T phones there.
My home is also made of stucco, which along with brick and cement block, is one of the worst materials for blocking signals.
If this only happens in one location, I would recommend contact AT&T and see if they will open a ticket. The probably won't open a ticket if your coverage is listed as "Moderate"
Hope this helps,
Nathan C.

Is there a software in which I can hook up my iPhone 4s to my computer and send and receive text messages and calls (via headset) through my computer?

Is there a software in which I can hook up my iPhone 4s to my computer and send and receive text messages and calls (via headset) through my computer? Whether it's free or cost money, can someone please give me a name of a program or software that allows me to do this? I can't seem to find anything like this for the iPhone.

2) I can sound very stupid since my head is aching I am not a regular plsql coder but from now on I would be one, please helpJust for your sake, to Compare 60 tables (Supposing you just want to verify count of records), you are writing an entire procedure; You might have completed this activity by now doing the manual way. By taking this way, you are investing time to generate a correct code (as you just mentioned not being a regular plsql developer) you are stuck with some un-identifiable issues.
As an alternate way, I would suggest you to export the data, after ordering, into a spreadsheet and then validate. Also, since it looks like you are comparing the data in the same database between schemas, you can also use the SQL Navigators Data Compare utility and there are many more readily available in market.
I would wish you the best if you still prefer taking the approach.

Simply way to make sub vi and call it form main vi

I'm a beginner and have major problems to make a sub vi and call it from main vi. I'm going to do a save dialog where is extra info for my saving and want to call dialog from main vi and after that save info to a file or database. I want that save dialog appears after i press button. I attach sub vi where is no functionality yet.
Attachments:
save_dialogsub.vi ‏21 KB

The first step is to connect the controls and indicators that you want to pass information to and from your main vi.
You right-click on the icon at the top right corner of the Front Panel and select "Show Connector". Typically put inputs at the left and outputs at the right side of the connector pane. Save it.
Open the main vi. Go to the block diagram. Click on "Select a vi" inside the Functions Palette. And choose the sub vi you prepared. Then wire it up inside your main vi.

Session method and call transaction methos which one is the sap recomonded

hi
PLease give me the answer to these questions.
session method and call transaction methos which one is the sap recomonded why .
2) if we want to maintain BDC program in all the systems.wt to d0

Hi Revethi,
Here is the difference between the Session and Call Transaction method.
Session
Session method supports both small amount of data aswell as large amount of data
2) data processing is asynchronus and data updation is synchronus.
3) it process multiple apllication while perfomaning validations.
4) in session method data will be updated in data base only after processing session only.
5) system provide by default logfile for handling error records.
6) it supports both foreground aswell as background process
in bdc we use FM ... bdc_open_group " for creating Session
bdc_insert " adding transaction and bdcdata table for updating database
bdc_close_group " for closing Session
Call Transaction
Call transaction exclusively for small amout of data
2) it supports only one apllication while perfoming validations
3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.
we can create logfile by using structure....BDCMSGCOLL
4) it doesn't support background processing.
5) data processing is synchronous and Data updation is Synchronous( default), in
this method also supports daya updation in asynchronus process also.
Syntax:
Call transaction <transaction-name> using BDCDATA
mode <A/N/E> update <L/A/S>
messages into BDCMSGCOLL.
