• How to set the session bean of backing bean variable

  Hi all -
  
  I have a bean with a session variable and I want to set the value of this variable to a bean of support. Could someone please suggest how to achieve this.
  
  I use ADF 11 g.
  
  Greetings-
  Rohit

  Hello

  First of all, you need get the referral of bean in the bean to support session, and call the method that sets the value of the attribute. Getting session bean reference - you can use dependency injection, which is the best way, but you must register your bean in faces-config. XML (not adfc - config.xml, see http://biemond.blogspot.com/2010/04/ejb-injection-in-jsf-managed-bean.html).
  An alternative is to search the session bean's JNDI.
  Third option involves data controls: you create a session bean data control and then expose the method to fix your attribute value, in the calling page to jspx pageDef. To do this, you can't use method that begins with 'set', because you will not be able to exhibit in the pageDef (at least not with the Visual Editor). Then, you can call this method from the bean to support using this code:

          BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
          OperationBinding operationBinding = bindings.getOperationBinding("yourSessionBeanMethodExposedInPageDef");
          operationBinding.execute();
  

  I hope this helps.

• We get an error "D: / is not accessible." a device i/o error"when trying to access hard drive

  * Original title: e/s problem

  I am not able to access my hard disk.windows that says: -.

  "D: / is not accessible." an i/o device error. "

  I also tried chkdsk but it says that it is not directly operatable.

  Hi Rishanpc,

  Thanks for the post. I am sorry to hear that you found a mistake "D: / is not accessible." a device i/o error"when trying to access hard drive.

  I imagine the inconvenience that you are experiencing. I will definitely help you with this.

   

   

  To help you suggest several steps to solve the problem, I would appreciate it if you could answer the following questions:

  1. have you checked if the cables are connected properly?

  2 what is an internal hard drive or external?

  3 have there been recent changes made on the computer before the show?

   

  The most common cause of a non-accessible i/o error is a disconnected cable. When the computer tries to access a device, and it's no response after several tests, it will generate this error. Another common cause is when a program tries to access a file that has been removed or eliminated.

   

  Disconnected Hard Drive/cable misconfiguration

   

  Internal hard drives require a specific set up. IDE hard disks can have only one master. If another hard drive has its defining together correctly pin code, a user is perhaps not able to access the data, and he will receive a message that the drive are not available. Cables come off inside the case of the computer also cause a not accessible i/o error. The user can correct this problem by opening the case and attach the data cables for each drive safely at the back of each drive and the motherboard.

   

  You can follow the steps below and check if it helps.

   

   

   

  a. go to "Control Panel" in the start menu and choose 'performance and Maintenance '.

  b. click on 'System' then go to the Hardware tab and click on "Device Manager."

  c. find the device that records an error by developing the appropriate category nodes. If the device has a red "X" on the icon beside its description, the hardware is disabled; Go to step d to activate it. Otherwise, go to step e.

  d. go to the general tab and click on "Activate the device" found in the device status section. then press 'OK '. (Note: you may need to follow the guests, as indicated via an assistant of favorable device.) If you do, continue to click "Next" and follow the instructions until the process is complete.) Test the equipment. If an error is displayed, go to step e.

  e. click the general tab and click "Troubleshooting" found in the device status section and then press 'OK '. Follow the prompts to fix the problem. If an error is still displayed, go to step f.

  f. click the driver tab and click on 'Update driver'. Follow the instructions until the process is complete and then to test the equipment.

  Hello raulganau, welcome.

  I suggest to try the system restore to restore the system to a date before the problem started. Try this...
  1. click on START
  2. click on "all programs".
  3. click on "Accessories".
  4. click on "system tools."
  5. click on "system restore."
  6 follow the instructions on the screen to restore the system to a date before the problem started
  Although the system restore does not target the personal data, I recommend always backup your personal data, just in case something happens.
  For reference, I have included a link that provides more specific information about the restoration of the system and how to use it:

  Hi PJ,.

  If the model of data or rupture of query query returns no rows - BEEP will throw Null pointer Exception error.

  THUS, our goal is to have 1 row who always gets compensated regardless of the logic of the report.

  It is only through a work around on the SQL query.

  Before spend you with this

  1. how many reports does need this change?

  2 are going you to the 11 g version all earlier?

  3. If you think that his evidence for this change just to make the fake success on your Planner screen message, then proceed to test the approach below.

  Application of model data:

  ****************

  For example

  / real request * /.

  Select empid as busrt_key,

  EmpName,

  empsal

  WCP

  where empdept in (10.20)

  Union of all the

  / * query dummy to return 1 row always regardless of actual query * /.

  Select 'burst_flag' busrt_key,

  empname null,

  empsal null

  of the double

  Bursting of query:

  ***************

  Choose burst_key KEY,

  'template_name' MODEL,

  "rtf" TEMPLATE_FORMAT,

  'pdf' OUTPUT_FORMAT,

  cases where burst_key = 'burst_flag' then 'NA' else 'EMAIL' end DEL_CHANNEL, - note here, for dummy value used to send us emails with just the key to the success.

  '- at-'email' "Parameter1".

  "e-mail-cc" PARAMETER2,

  "email - of" parameter3,.

  "email subject" parameter4

  PARAMETER5 "-body of the email."

  PARAMETER6 'true '.

  Of

  (

  / * your logical real burst of request but just only the select clause that you will use in the KEY * /.

  Select empid as burst_key

  WCP

  where empdept in (10.20)

  Union of all the

  / * query dummy to return 1 row always * /.

  Select "burst_flag" as burst_key - this value hardcoded must be synchronized in the data model and query failure

  of the double

  )

  Impact of the model

  ***************

  If you have aggregation functions in your RTF model such as sum() and count(), let me know.

  Due to the addition of an additional dummy query, 1 row with a null value is generated which cause problem NAN (not a number) to your model. But that can be handled.
