• [ADF, JDev12.1.3] Java webservice class methods mapping: which are the best practices? I seek advice from experts...

  Hallo,

  in my application (let's call it "MyADFApp"), I created a Java class (let's call it 'Services') which maps simply a C++ application methods (let's call it "Différendsapp") similar to a Web service.

  "Différendsapp" works on the same machine where the "MyADFApp" (works on Glassfish).

  I need to use the 'Services' methos both in the model layer and ViewController so:

  • I imported 'Services' in the AppModuleImpl
  • I created in the AppModuleImpl method for each method of 'Services '.
  • I exposed these new methods of AppModuleImpl for the ViewController
  • I configured class 'Services' to call "Différendsapp" on localhost since it runs on the same computer in 'MyADFApp '.

  In AppModuleImpl, I can call 'Services' methods directly while controlled beans think I call these methods to help

      BindingContext bctx = BindingContext.getCurrent();
      BindingContainer bindings = bctx.getCurrentBindingsEntry();
      OperationBinding operationBinding = bindings.getOperationBinding("ServicesMethodToCall");
      operationBinding.getParamsMap().put("param1", param1value);
      operationBinding.getParamsMap().put("param1", param2value);
      operationBinding.execute();
  
  

  I am a beginner and I would like to know by experts if the instinctive approach I follewed is good or not and if JDev/ADF offers me a better way to use my class of 'Services '.

  For example, I tried to convert my class of 'Services' in a DataControl and I wonder if will work it after you have configured the class to use localhost or not.

  I wonder if after you have configured the class to use localhost will work in the case I have to import/use also the class directly in managed bean (which I did in AppModuleImpl).

  I would be happy if you could answer my questions and give me some explanation.

  Thank you

• "Windows Media Center cannot detect the IR control cables, which are necessary to control the set-top box. Fixing parts IR that supports the IR control cables and then try again. IR HARDWARE NOT FOUND ".

  Original title: when setting up Windows Media Center, I get the error message: "IR hardware not detected".

  I have an internal TV Tuner that has been installed by HP, when I bought recently a "computer build-your-own." (According to the control panel Device Manager, my tuner is a Win TV HVR 1290, made by Hauppauge). The computer came with Windows 7. While installing Windows Media Center, after setting up the TV Signal (on channel 3) I am able to see a video thumbnail on my computer screen. I am also able to change the channel using my remote control U-Verse (not the Windows remote control supplied with the computer). So far so good! I then hit next and get the following message: "Windows Media Center cannot detect the IR control cables, which are necessary to control the set-top box. Fixing parts IR that supports the IR control cables and then try again. IR HARDWARE NOT FOUND ".  After you receive this message, the installation procedure is completed. I called HP that support intalled the tuner. They had not the slightest idea what to do. I then called Hauppage customer (manufacturer of TV Tuner). They said that I need to plug one end of the IR Blaster cable that shipped with the computer in a slot in the back of my computer (they told me which slot). They said so to run the IR all the way cable to my cable box and the other end of the cable to my cable box of band. They said it was necessary to be able to use my Microsoft Remote to instruct the box to change channels (cable IR stuck on the box). I told her that I did not use the Microsoft Remote, I could change the channel with my U-verse remote (that I preferred to use anyway). He said that it took the cable on the band decoder in order to remove the error message and the installation of Windows Media Center. I then called U-Verse technical adapter who informed me of their set-top boxes (made by Cisco Systems) do not have the ability to receive signals IR IR Blaster cable (or any othe IR signal source). Microsoft is apparently not understand how U-Verse set-top boxes are designed to work and sells a product incompatible remote control/IR. My question is this: How do I set up Windows Media Center, in order to avoid getting the error message "IR hardware not detected" when you install Windows Media Center and just use the remote control of the U-Verse that I prefer to use in the first place. Once understand you this point, please send the information to HP, At & T U-Verse and others. Thank you.

  Ron, I have something for you!

  and for all the people who have this problem :)

  Hi, I had the time of IR not detected in Windows 7 Ultimate with a TV wonder 650 card and a box of digital adapter from Verizon for my PC... Go on the road to installation and after the Media Center channel search, choose manual configuration. Choose the aerial signal (I aso picked after this analog) l. After he sought more, he finds no channels.  Do not be afraid. Just accept it and go to the main settings page in the Mediacenter. If I remember correctly, then select TV Guide. Choose Add channel. I added the channel 3.

  Since my Verizon box has no IR for the computer, I added the channel 3 for the media Center and I change the channels with my Verizon remote. All my stations in the Verizon box go to Channel 3.

  The story here is so, for some reason any Windows detects that only my box channel signal TV and you must manually configure the media center on the air, then go to settings and add the channel you want in the guide.

  Why the guide TV control which channel you can tune is beyond me, but the scanner locks all channels, it does not detect. they must be added manually in the guide.

  My TV works and looks okay now.

  It actually works!

  the only problem is that it is not in HD

• [ADF, JDev12.1.3] Why the content of a line in my af:table disappears when I select a new line?

  Hallo,

  I created an af:table like this https://community.oracle.com/servlet/JiveServlet/downloadImage/2-12620067-7140/cmnt1.png following the advice that the kind has been suggested to me by Ashish (for details, see [ADF, JDev 12.1.3] how to display multiple records on the same page... not in a table, but display a form for each record)

  When the table is loaded for the first time, it appears correctly.

  But often (not always) when I select a new line, the selected line up to become "white" and its content disappears http://digilander.libero.it/flattit82/OTN_FILES/rowDisappearing.png

  This product especially if I change the value of 1 or 2 fields contained in the line.

  If I select several lines - one after the other one - the part visible AF: table may become totally white.

  Looks like a refresh problem.

  The table is in a tab.

  If I switch to the tab, then I it again once the table appears again correctly.

  Another thing I noticed: for example 2 rows have disappeared, I select an end of line I have empty in a required field: when I select another line, the popup "this field is required" appears in the row selected previously and magically all the missing lines are coming back!

  The problem seems to be less frequent if I set the selection table = none... but it is always present.

  You could you kindly help me to solve this problem?

  Thank you

• [ADF, JDev12.1.3] When you use create/restoreSavepoint... Restore operation is still useful? And other doubts...

  Hallo,

  Dario and Timo advised me (in this thread Re: [ADF, JDev12.1.3] Master w/playback af:form only af:tables detail: how to handle insert and edit through forms?) I make a request using the functions create/restoreSavpoint to this fragment in my application.

  

  The tables are read-only, and the user can insert and modify records by a form of popup.

  Each table has its own pop-up that I created using a btf executed as diaolog (*).

  Before I open the popup, I create the backup point.

  BindingContext bctx = BindingContext.getCurrent();  
  DCDataControl dcDataControl = bctx.getDefaultDataControl();  
  String sph = (String) dcDataControl.createSavepoint();  
  AdfFacesContext.getCurrentInstance().getPageFlowScope().put("AdfmSavePoint", sph); 
  

  When the popup is closed, I restore the backup point if the Cancel button was clicked...

  Object confirmOrCancel = returnEvent.getReturnValue();  
  if (((String) confirmOrCancel).equals("cancel")) {  
    String sph = (String) AdfFacesContext.getCurrentInstance().getPageFlowScope().get("AdfmSavePoint");  
    BindingContext bctx = BindingContext.getCurrent();  
    DCDataControl dcDataControl = bctx.getDefaultDataControl();  
    dcDataControl.restoreSavepoint(sph);  
  } 
  

  I have these doubts:

  1. the button "CANCEL ALL" (so far) AM restore operation is still meaningful (is always useful) when you use the check points? Or can I avoid using the restore of the AM operation, creating a backup point before you enter the fragment and restore it if the user clicks on "RESTORE ALL"?
  2. for all tables: before opening the popup insert/change the backup point is implemented pageFlowScope under the same key 'AdfmSavePoint '. Is it OK or would it be better to use a different key for each table (for example 'AdfmSavePointTable1', 'AdfmSavePointTable2',...)?
  3. If the pageFlowScope already contains a checkpoint under the "AdfmSavePoint" key... What does if I give the floor to new .put ("AdfmSavePoint", sph)? Can I be sure that the old value is overwritten?
  4. is this safe with nested savepoint? For example in my case I want to create a backup before the fragment in the image point is displayed (and restore if the user leaves the fragment by clicking "RESTORE ALL"), then within the fragment, as I said above, I would manage other points of record when inserting/editing tables.
  5. I noticed that clicking on the button "RESTORE ALL" when it relates to the AM-restore operation causes this strange thing: when before displaying the fragment I call SetCurrentRowWithKey on the master istance VO... If I click on "ROLLBACK ALL" posted master VO Records changes and 1 minutes of the main of the VO table is displayed. Why the master istance VO is not reimain in the folder I've previously selected by SetCurrentRowWithKey?
  6. With reference to the expression (*) above. The BTF 'dialogue' I created contains only the page jspx with shape and a return to activity. I also tried a) create (and restore) the backup point, b) to call createInsert inside the "dialog box" operation BTF (see images below), but the createInsert on retail VO istance called inside the 'dialogue' BTF seems not to reflect on the table as when I call createInsert by calling btf. I have to make some adjustments in the 'dialogue' of BTF?

  

  

  Thank you

  Federico

  Federico,

  (1) Yes, what should happen if a user add or edit vo1 and click ok in the dialog box but decided that ask to work must be restored?

  (2) as long as you don't have that a dialog box is open, it should work.

  (3) the flowrate range of page is a map. You can put the same key more than once. If the key already exists, the value is replaced.

  (4) in fact, I don't know, but the sounds of complicated design. I guess you can record more points, but only in the order of creation. It's as if you try to rebuild the framework. BTF yo it even for you, when worn right. Please go to ADF Architecture Square and read and watch it task flow of related things.

  (5) this behavior is as expected. A restore resets all the iterators so thagetto point at the top of he. http://www.Oracle.com/technetwork/Developer-Tools/ADF/learnmore/OCT2010-OTN-Harvest-183714.pdf 'keep the line after cancellation' shows how to handle this situation.

  (6) I suppose have you refresh the table iterator, once you close the dialog box for the new data. But that's only a guess because it depends on how the btf share control of data and the your involved.

• [ADF, JDev12.1.3] Mastering the form with detail tables: questions about Insertion/deletion, commit / rollback, primary key, handling,...

  Hallo,

  I have a panelTabbed with 4 tabs. In the 1st tab, there is a master form while each of the other tabs, there is a secondary table. Each tab "reads" vo.

  Please see here http://digilander.libero.it/flattit82/OTN_FILES/VoInTabs.png

  I created the graphichs/layout and now it's time to take care of the management of the transaction.

  In the master tab / form

  1)

  Here, I would put a button to remove the master record.

  When I delete a record in the primary table an automatism in the database (MS SQL Server) will automatically delete any registration which are linked to it in the detail tables.

  Could the automated system as this causes problems?

  In the Details tabs / tables

  2)

  I would put a button in each row to delete the line delivering. Can I just drag-and - drop, like button, af line: table the operation "Delete" of the VO istance detail used to create the af: table?

  3)

  If Yes, by clicking on the button performs the default delete operation. But if need to perform some actions before you run the deletion (or, in General, any other operation), how can I do?

  4)

  To create a folder that I use Create or CreateInsert? And what are the differences between them?

  5)

  When I create a new record I need set the value of a field of the VO on which is based the af: table. He filed, let's call it RowDetNumber, is not displayed in the af: table, because it doesn't have be filled in by the user. Mut value is calculated and set "secretly" before posting the new line to the database table. In particular, its value must be calculated as

  Select max (RowDetNumber) + 1

  of table_on_which_VO_is_based

  where some_conditions_on_fields_of_the_same_VO

  
  

  For example

  The VO selects all of the records that have FkId =: value. If value = 3, VO selection records:

  ID RowDetNumber OtherFields FkId

  1   3     1             ...

  2   3     2             ...

  3   3     3             ...

  4   3     4             ...

  The new record must be RowDetNumber = 5.

  I would like to know how permorm this.

  In general

  6)

  If the database tables have 1 or more triggers I have to take care of something?

  7)

  On the book "development of Web Applications with Oracle ADF Essentials - Sten E. Vesterli", I have read it could be problems when you use tables of database non-Oracle with auto-increment fields.

  The advice of author uncheck the 'Required' box in the model.

  All tables in my database have a primary keys that are auto-increment... so I uncheck the "mandatory"?

  8)

  In general how do I set these fields? I have to put in OT, VO or both?

  

  Thank you

  Federico

  Hello

  (1) you will need to re - question child iterators so that they do not look stale data

  (2) Yes. Ensure that the table is PPRed after deleting the line (should happen automatically if ChangeEventPolicy on iterator is set to ppr)

  (3) double click on the button and it creates a bean managed for you. It allows you to check a box to generate the code he would run to remove the line. Everything you put in front of the generated code is your code before

  (4) in the case of tables, use createInsert as it adds the new line to the rowset (transaction)

  (5) suggest to do this use a database trigger and the data attribute value DBSequence VO type

  (6) do not 'drop table' issue in SQL (sorry, couldn't resist ;-))

  (7) If you follow the advice of the author, Yes. What it does, I have it does not throw an exception if a value is missing in the validation of the line

  (8) usually you set whatever it is at the level of the OS and put only things on VO if you want to override the default value for a specific behavior

• ADF change active tab when the button is clicked

  This is one of those questions that expose me for beginners I, but here goes.
  
  I went through the help files and the forums, and I can't find what I think is a relatively simple mechanism: change the active tab (revealed) with the click of a button or menu text link.
  
  For example: I have a navigation bar on the left of the page and a set of tabs in the Center. A tab is active. I want to be able to click a button in the navigation area and have the visible tab changed to tab B, as if I had clicked on the tab B itself. How to activate a button or link click in the navigation area to change the visible tab? I only need that in some specific cases and do not want to create a complex structure backend for a pair of buttons.
  
  If you know a way to do this, I'm all ears. Thank you.

  You create a bean of support that will contain the code for the event click on the link.
  In this code, you set the property disclosed in the showDetailItem you want to make active to true and then change the tab other false.

  An intro base to work with the support of the beans is here:

  I'm doing a text box appears in a PDF document in InDesign when the cursor of the user hovers over an another textbox, and I want it to disappear when the cursor moves off the coast of the first text box. I tried the following with adjustment of various, and it does everything just for me.

  Display a different button on turnover

  You can create a hotspot in which clicking or mousing over an object contains another object. To do this, create two buttons, hide one of the buttons and use the show/hide button action to show and hide the button target.

  • Create an object to use as the "source" button. In the buttons Panel, click the icon of the object to convert to A button.

  • Place the image you want to use as the button target and convert it to a button.

  • Select the target image and select hidden until this that triggered at the bottom of the Panel buttons.

    The image must be hidden in the exported document that can be displayed when the "source" button is clicked or wriggle on.

  • Click the source button and create two different actions, one for show the image target and target the other to hide the image.

    If you want the image to appear when the mouse is over the button source, use events on Roll Over and On Roll Off. If you want the image to appear when you click on the source button and disappear when you release, use events on a click and release. In both cases, use the show/hide action buttons to show or hide the target button. See the interactive buttons.

  • Use the Preview Panel to test the buttons.

  Should work...  On your last point (not 12?) I get the feeling that you have exported your doc as Adobe PDF (Print)? You must instead use (Interactive) Adobe PDF...

  

• How do I update the graphics drivers when the latest "official" HP drivers are released more than 3 years ago?

  How can I update readers on my graphics from AMD for 1) HP has not updated their more than 3 years and the vanilla AMD drivers do not work on HP laptop?

  Model DV7t-6100

  AMD Radeon 6100 m graphics card

  Win 7 Home premium

  If you know which driver you need to upgrade to, there is a way to install it, even if HP does not sgned offshore on the pilot. The problem with unsigned drivers is that they could lead to the instability of the system. If there are questions, HP you will have to roll back the driver to their official, until they will offer support. If you want to proceed with the installation of the driver from the site Web of AMD, I would recommend downloading their tool which scans your system, and shows you which driver is the right one for your system. It will take much of the guesswork out of the process. The worst thing you can do is use this process to install the wrong driver...

  I used this process with an Intel driver, but the process will be the same, just the file names may be slightly different. If you have any questions, let me know and I will try to edit the list here to reflect the actual driver, you are wanting.

  1. go to your site the graph of manufacturers (Intel, Nvidia or AMD) and download the utility which scans your system. If not, find the right driver for your system.

  2. download the .zip, NOT the free installation package file and save it to your desktop for easy access.

  3 extract the .zip file, so you can access the files inside.

  4. go to Device Manager, expand "graphics cards", right-click on your graphics card and click on "Update Driver Software".

  5. Select ' Browse my computer for driver software

  6. choose "Let Me pick from a list of drivers on my computer".

  7. Select 'Have disk' and in the box that appears, select Browse

  8. go on the desktop, find the files extracted, select "Graphics".

  9 select the file with a .inf extension. This is the real driver file.

• How to run the rman output files, which are more days of retention

  I use for my rman backup tasks.

  I have format my output files of rman to a specific path, instead of the fast recovery area.

  Also, I spend below command in RMAN

  RMAN > CONFIGURE RETENTION POLICY to RECOVERY OF 7-DAY WINDOW;

  And the "control_file_record_keep_time" parameter is also set to 7.

  I've been running rman for 8 days. Everything seems good. But I find several rman output files are more than 7 days.

  So, I just want to know how to handle the rman output, which is longer than 7 days files?

  In fact, I assumed that these older files should be obsolete files, but rman is not to declare that they are obsolete.

  So how do now?

  Windows 7 day average recovery rman will protect everything necessary for the recovery to any point in time in the last 7 days.  In fact, in the last 604800 seconds.  The same will mean that he need the files OLDER than that.  Simply because a backupset is older that your recovery window does NOT as yet, it is obsolete.  Any recovery begins with the last FULL or INCREMENTAL backup ZERO before the recovery point.  And it does not matter how old the backup is, it will be obsolete.  Suppose you take a level 0 backup, 1 January and for the rest of the year taking nothing but level 1 and backup archivelog.  31 December than and only the full backup will still not be obsolete, even though he is a year old.
