Can i call Bean managed EJB with transaction attribute Required New

          I am calling a BeanManaged EJB which has a transaction attribute
          set to Required New from a container managed bean. Does it create a new transaction
          other than the Bean managed transaction. Do i really need a required new field
          transaction attribute.All i need is user controlled transaction.Do i need to set
          the transaction aatibute.
          Thanks
          Krish.

Hi Krish,
          The question does not make much sense.
          I would suggest that you set all your tx settings to "Required" unless you
          have a specific reason to do otherwise, and in those few instances that you
          have a specific reason to do otherwise, then change it in just those places.
          Peace,

Help-Problem in calling JMS inside an EJB having transaction attribute Required New

          Hi,
          Version wl 5.1 service pack 8
          OS - unix
          I am using a Container managed bean say Bean1(transaction attribute Required)
          which in one of its method is trying to call another EJB say Bean2 which has the
          transaction attribute set to "RequiredNew".Inside the method in Bean2 i have my
          JMS funtions coded to persist to database.JMS uses Queue connection factory and
          is an non transaction JMS session.The JMS server is running in a separate weblogic
          server and not in the server where EJB is deployed.I use the url of the JMS server
          and get the context of that server and connect my JMS.
          The problem that i am facing is
          I do the transaction in bean1 and the i make the call to bean2 to do the JMS work
          and i can see the JMS doing the insert in the table and everthing works fine.But
          after few seconds i can see the exception/message seen on the console of the weblogic
          server where my JMS server is running as below
          Tue Sep 04 15:57:09 CDT 2001:<I> <TX> Transaction (TxC (30486015, xid = 99963563
          2756_5, timeout = 30, txState = Marked Rollback, root = 829817264280676325S10.51
          .110.237:[7001,7001,7002,7002,7001,-1]/326) rolled back after 30 sec.
          After this happen i dont see any roll back in either bean1 or bean2 or the JMS
          insert is rolled back.
          I don't know why this exception is thrown and no effects on the rollback and it
          works the way i wanted.But the only thing that keeps bothering me is the rollback
          and why does this happen.
          Thanks
          Krish.


The exception your seeing is troubling - if the tran is rolled
          back than whatever work is associated should also roll back. I suggest
          instrumenting your code to see if the tran rolling back is the same tran
          that is being used for the transactional application work that appears to succeed.
          Also, try forcing a rollback, you may see that the EJB work truly rolls back
          while the JMS work does not.
          I'm not really familiar with 5.1, but I know there is a fundamental limitation to one
          phase commits, this means that the JDBC connection pool used by JMS as well
          as that used by the EJB must be one and the same - I'm not exactly sure how
          it works, but I'm pretty sure multiple servers can share the same connection pool.
          This post seems unrelated to clustering, if you need further help, I
          suggest posting in the ejb or transaction newsgroups.

HT1212 my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone

my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone?

I have to believe this has something to do with iOS 7 issues. I have taken my screen blacked out 5s twice to the Genius Bar and the found a bunch of system apps had crashed. So if this is the case, is iOS7 the problem?

How can I call a plsql function from an attribute?

I have an attribute defined in an element. I want execute a PLSQL function from the attribute, and display the returne value with an HTML template.
I've defined the attribute's type like PLSQL, and I've put the called of the function in the value of the attribute, but it doesn't work. The only value I obtain is an URL (I think that is the URL of the function or someting like this).
How can I call to my function from the attribute and display the returnes value in the page?
Thanks.

Thanks, but it doesn't work. I have an attribute called ID_BOL and I want to associate a sequence to that attribute. I've created a function, with the sequence. This function return de value of the sequence. I want taht the attribute takes the value of the sequenece dinamically.
I've tried it, creating the type attribute like PLSQL, and calling the function from the attribute, but it doesn't work.
How can I return the sequence value to my attribute?
Thanks.

Why can I no longer use AirPlay with my Slingbox? New updates break complatibility?

Why can I no longer use AirPlay with my Slingbox? New updates break complatibility?

You already seem to know what the issue is, it is the parallax feature that was added to iOS 7. From your rant, it appears that your attempt to work around this was not successful. According to the Apple documents I've seen, they recommend that you enlarge your image (not reduce it). Make your image have excess space on all sides, which is not displayed on the screen. This way, when you tilt your device one direction or another, it can shift the image to give the appearance of 3D.
As a photographer, I like to use the full frame of my images, but I also know that I need to leave room around the image as well. I have some photos I have taken that I can't use because I have them cropped too tightly too, but I have others that work just fine. Just remember that part of the image file is "off screen" so that if iOS has to shift the image up it has some image that can scroll onto the screen. It needs this space on all sdes, so just make youre images larger, and keep in mind that a portion on each side will be outside the normally visible screen... If you don't like this feature, you can always go into the settigns and turn it off.

Can I install Windows XP SP1 with Bootcamp on my new Mac Mini 2011 i7 ?

Can I install Windows XP SP1 with Bootcamp on my new Mac Mini 2011 i7 ?

Baiscally if your Mini came with Lion Pre-installed new then No you can't use XP.
The Lion installed computers no longer support XP OR Vista via Apple's Boot Camp.
For one thing Apple only supported XP with SP2 in order to install it on pre Lion computers.
If the Mini had come pre-installed new with say 10.6 then you could have installed XP and still of been able to upgrade to Lion without any issues as you already have the drivers for XP installed. Lion only has the drivers for W7.

Weblogic.management.security with transactions, Please HELP

I am using weblogic.management.security.authentication API to programmatically insert/delete users and passwords into/from default security provider on Weblogic Server 8.1. I want to add transactional support to this these actions, I tried using UserTransaction API but without any luck. Does weblogi.managment.security.authenication has no transactional support (rollback-commit) or am I doing something wrong? I very much appreciate your help and looking forward to hearing from you!!!!
It doesn't rollback, Here is the code:
UserTransaction transaction = (UserTransaction)ctx.lookup("javax.transaction.UserTransaction");
transaction.begin();
UserEditorMBean userEditor = (UserEditorMBean)providers;
userEditor.createUser(userName, password, description);
transaction.rollback();

I do not think you can have transactions over MBean calls as they communicate with relevant object over t3 and this objects are possibly in different class loader.

Can LabVIEW call a DLL built with VS(2005) C++ with /CLR and Without an Entry Point

My project requires me to convert a C++ program to a DLL and having it called by LabVIEW. Due to the complexity of this C++ program (converted from fortran using f2c -C++ option), it cannot be compiled without using /clr option. I did build the application standalone (/clr), and it functioned fine. When I build it into DLL using VS2005, I was forced to use No Entry point option and without using DllMain in the C++ code. Eventually the DLL was built without error. But after I call it from LabVIEW, I was not getting calculated results as expected. I added a testing function to the C++ code of the DLL and just try to modify a parameter, it will not, but only return the input numbers. I was passing data by pointer and not by value, so I expect this parameter output be modified. I suspect that the DLL didnt get executed at all as it has no entry point specified.
Am I on the right track to approach this task, or I am heading to totally wrong direction here? I believe due to the fact that my C++ was from f2c and use vsf2c.lib and so on, the code is managed code, so that a regular DLL cannot be built from it with an entry point. How can LabVIEW call such a DLL? Am I right on that? I really need your advice here for a right approach to this problem and possible implementation "watch outs"...Thanks!
Bryan

Hi...Finally I was able to compile my code with an entry point defined and without using /clr. I can also call this DLL from LV and got back a variable from a little test function added to the DLL. But the function that was used for my main application in the DLL crashed LV and I got a pop up box from Microsoft Visual C++ Runtime Library: Runtime Error! "This application has requested the Runtime to terminate it in an unusual way, please contact the application's support team for more information". In Visual Studio I also got the following message: (I eliminated most of the "No symbols loaded" messages that are not errors but just info.) I would apprciate if someone can take to look with your more "experienced eyes", many thanks! Bryan.

Can we call a Function Module with in a loop

Hi,
Can we call a Function Module within a loop . Does it reduces the performance.
Can you please guide regarding this.
With Best Regards
Mamatha.

hi Mamatha,
You can call .. but it is better to avoid calling it within a loop...
Loop at it_tab.
   call function 'CONVERSION_EXIT_ALPHA_INPUT'
    exporting
      input = it_tab-vbeln.
    importing
      output = it_tab-vbeln.
endloop.

Issue with Transaction Attribute

Hi All
I am trying to build a program that will interact with two database at the same time.Lets say, I am getting/updating/inserting data from/to Database1.table1 so I am creating transaction attribute for the same to commit and roll back the changes.
Now, after the above scenario I need to update my audit trail table in database2 but since I have already created transaction for the above database it not allowing me to connect to database2 saying "Connection already exit for database1 cannot create new transaction for Database2".
Also if I tried to create a new transaction for Database2 its passing me exception saying "A transaction is already running for the thread cannot create new transaction for the same thread".
I tried calling a new thread also but the exception remains as the new thread is called from the main thread.
Please help me in same so that i can create two transaction or connection to two database using same transaction.

user12882304 wrote:
... connection to two database using same transaction.Not possible.
You are attempting something with a JDBC driver that the driver does not support.
Your first step is to research distributed transactions.
For this to actually work the database itself must support it. And you must use the correct idiom to invoke it.

I can't sync my iPad 3 with iTunes using the new Macbook Air

When I connect my iPad 3 with its original cable to my new MacBook Air, the charge symbol in the iPad starts to blink and the iTunes keeps connecting and disconnecting the iPad (more than one time per second).
I can sync my old iPhone 3GS with the new Macbook Air and I can sync both iPhone and iPad with my old 2009 MacBook.
I found similar questions in the forum, but didn't find a solution. I can charge my iPad using the outlet, by I still need to backup and sync the iPad.
BTW, every software is updated.
