• [ADF, JDev12.1.3] Problem of formatting attribute VO MONEY when exports it as an Excel file using apache.poi

  Hallo,

  I have a VO with an attribute based on the field of database of MONEY.

  In the configuration of the VO for the attribute I put:

  • In the "Details" tab: Type = BigDecimal
  • In the "Indications of the UI" tab: Format type and Type like the image below

  

  These settings allow the value of the attribute (in the table, inputText) appears with thousands and decimal separator that according to my language - Italian - are. (point) and, (comma).

  For example. Silver number displayed correctly:

  10.123.000,37

  When I write the value of the attribute in an Excel cell using apache.poi...

  cell.setCellValue (attr.toString ());

  ... I see in the cell...

  10123000.3700

  ... Although I'd like to see what...

  10123000,37 (not thousands separator, the comma as separator decimal and only 2 decimal places)

  
  

  You could you kindly help me to get there?
  

  Thank you

  Federico

  Federico, this isn't really a question JDev or ADF. This can be solved by setting the cell format to the cell, you write the number. Like oyu would in excel

  style.setDataFormat(HSSFDataFormat.getBuiltinFormat("#,##0.00"));

• NULL pointer exception when you use the tag ahref

  Hello
  I am writing a file html for the file adapter. Inside the transformation, if I understand ahref* tag, I still get null pointer exception and a 0 KB file is written.
  
  However, if I remove the < a href > tag from the code, the html file is generated correctly. But I need to use ahref* tag. Pls help me solve this.
  The details of the error are:

  Hello
  The custom XSD file is not necessary.
  Looks like it's a bug in file 10.1.3.4/10.1.3.5 adapters - it works very well in 11g.

  Whenever there is "a href" tag in the xml support to write to the file, the file adapter tries to get the content of the url real in 'a href' and written to the output file. When I try with any url (say http://www.google.com), the content of google.com is written in the file. If this URL is not accessible (for example http://foo.bar), then you get the null pointer exception. In your case, I think the URL that you are using the payload, is not accessible from your box of soa, or is not a valid URL.

  As a work around 10.1.3.4, I was able to create the XHTML file as follows:
  1 change the link partner of file adapter to use opaque scheme.
  2. in an assign operation, affect the load XHTML to a string variable using ora:getContentAsString ().
  3. Add a java embedding base64 encode the string as follows and assign to the entrance of the file adapter invoke:
  (HTMLString is the string from step 1 variable, InvokeWriteHTML_InputVariable is the input variable to the call on the file adapter operation)

  4. call the file adapter using the input variable in which is written the value encoded in base64.

  you could use the workaround above or rethink your design (if you want to create the XHTML file using bpel only or other means).

  Hope this helps,
  Kind regards
  Yohanna.

• Difficulty facing export .xlsx by Apache POI

  I use Jdeveloper 11.1.1.7

  I need to export .xlsx file af:table using Apache POI. I have not used all the attributes of VO in my af:table. I need to export only the visible columns in the same order as in the user interface.  The user may change the order of the columns in the user interface, so I need to look at also.

  I followed http://www.techartifact.com/blogs/2013/08/generate-excel-file-in-oracle-adf-using-apache-poi.html#sthash.CaVkCeKl.dpbs for reference. Here, he is given to browse all attributes in VO and exported in excel via apache POI. So, I could not able to follow this approach. And I couldn't use the HeaderText property in af:column to match with the attributes of the VO, since we used a different name for HeaderText in the user interface.

  So please guide me to achieve the requirement.

  Thank you and best regards,

  Assia.

  There is a lot of work.

  For starters, take a look at:

  https://technology.AMIS.nl/2012/03/02/ADF-11g-programmatically-repositioning-columns-in-a-rich-table/#prettyPhoto

  and attention to

  reorganizeColumnsInTable()

  function

  In this way, you can browse columns of tables. Now, in general, inside the af: column, you have a few af:outputText, which tells you what attribute VO are displayed in this column.

  So download af:outputText (child column) and see what is the "value" property, for this you can use

  ValueExpression ve = outputText.getValueExpression("value");
  String valStr = ve.getExpressionString();
  

  the valStr will be something like:

  #{rank. EmpName}

  Parse this string to get the real name of the VO (EmpName in this case) displayed in this column attribute

  ... had a point?

• Why Oracle ManagedDataAccess (4.121.1.0) throws a System.FormatException "first chance" exception to the debugger when you use OracleCommand.BindByName (on some machines, but not others)?

  Why Oracle ManagedDataAccess (4.121.1.0) throws a System.FormatException "first chance" exception to the debugger when you use OracleCommand.BindByName (on some machines, but not others)?

  This occurs when calling a ref cursor-returning packaged function stored with OracleCommand.BindByName set to true.

  When BindByName undefined, it works as expected.

  I've only been able to recreate this problem on a machine in my control. This issue has also reported to me by a customer.

  I tried to change the locale of the system of EN - UK EN-US, but I was not aware of any change in behavior.

  Similarly, I've tried explicitly overriding the default locale of the system with the OracleGlobalization parameters, and it also had no effect.

  Please see the example below.

  Thanks a lot to qualify again for me Alex.  I'll try upgrading to the latest version of the provider.

  The difference in behavior between the two hosts was found to be reduced to differences in configuration VS.

  Checking 'Just my code' prevents the first chance thrown in the debugger exception. As in fact, the exception is handled in the provider, it is enough for me.

• [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.

• problem in the form of master-detail when you use the ADF table for detail

  Hello
  
  jdev version - 11.1.2.1.0
  
  
  I create master shape detail using datacontrol drag as ADF master shape secondary Table.
  
  
  Now when I create a new line in the detail table using the key CreateInsert a new empty row created on top of the secondary table.
  
  and other show line that the previous record data based on the master.
  
  problem is I want to when I click on the createInsert button all the line of the secondary table must be empty and what line to fill two or three user then validate.
  
  
  
  Thanks in advance

  Hello

  If a secondary table has data, then createInsert adds to them. If you want to hide the existing lines, create a new instance of the View object and set the option "extract database" to "No. Rows. Use an af:switcher to change the specified table when the user clicks the createInsert button. There is some coding needed to have this use case in the ADF, but its essentially declarative. Bottom line, is that there is no option automated other than to create new lines in a separate page or dialog box if you are bothered by existing lines

• Can I process Excel BIFF5 files, or simply abandon Apache POI?

  For the experienced:

  Now looking back, I realize account I got what I got with Excel file (.xls file) was opened in Excel 2007 and clicked on the "Save" button. And it's all OK POI learning by the transformation of this file.

  Where do you find excel files? Would it be possible to have the provider upgrade its machines to provide the latest files?

  You can try the 'other' Java API Excel, JXL or whatever he called to see if she can manage obsolete formats.

• Hanging application while created workbook XSSF (Apache POI)

  Hello

  We have developed an application (using Netbeans) which, in a single windows is asking for some parameters, reading a few Oracle database data and creating a xlsx spreadsheet on the client side.

  Everything works fine, but we have only one user (among 20 using our application) who has a problem. When the application needs to start creating the file xlsx, it hangs, the file is not yet created on the client side. This only happens on a specific computer

  We cannot reproduce this behavior in our development environment, or in any other machine.

  I tried to create a file xls xlsx (using the HSSFWorkbook instead of XSSFWorkbook) and the problem is not displayed in his laptop. So the behavior seems to be specifically associated with this problem. The Apache POI library used is 3.11.

  Is it possible to track client (no right to administrator unfortunately on this machine) and see exactly what causes this problem only on this machine?

  Note that only JRE is installed on this computer.

  Kind regards.

  Alberto

  Hello

  After you find the error and cheking out how Netbeans using the path class the only problem that could cause the problem was an external library during installation of the JRE.

  For some reason any on the laptop user, there was a library external xbeans.jar (lib/ext under JRE path) including and the old version of the XmlOptions class.

  Remove the old library xbeans, jre lib/ext pot has solved the problem.

  Kind regards.

• Using SQL Server with ADF BC and getting Houston - 29114 ADFContext aren't Setup error

  Hello... I work with ADF BC and my connection is with a MS SQL Server database.  I added the sqljdbc4.jar in my template project, and can't seem to connect with the DB and build an Entity/View/AppMod infrastructure.  However, once I deploy the application on the integrated WebLogic Server I get errors when ADF BC tries to connect.  I added a POJO supported data control and tried to debug but PPR reports an error when my key to call the code stripped of JDBC:

  Houston-29114 ADFContext is not configured to process this exception messages. Use the code of exception stack trace and error to investigate the root cause of this exception. Root cause error code is Houston-29000. Error messages settings are {0 = java.lang.NoClassDefFoundError, 1 = com/microsoft/sqlserver/jdbc/SQLServerException}

  ADF_FACES-60097: for more information, see the error log of the server for an entry beginning with: ADF_FACES - Exception during the PPR, #1 60096:Server

  Seems to me that the POT is not in the classpath on the WLS.  What is the problem? If Yes... How would have added that JAR, sqljdbc4.jar, the path of the WLS class.  I've done through the deployment of models, and he saw in the META-INF/lib directory that has been deployed.

  Thanks for any help!

  Do not apply the JDBC JAR (s) in the archives of application deployment. You must add the JAR to the classpath WLS JDBC (s). Change the commEnv.cmd/sh for this script:

  Using JDBC with WebLogic Server - 11g Release 1 (10.3.6) drivers

  Note that WLS is pre-configured with a number of brand WebLogic DataDirect JDBC drivers (including a SQLServer driver), so you can use it instead of adding a new driver if the DataDirect driver meets your needs:

  Using WebLogic brand DataDirect drivers - 11g Release 1 (10.3.6)

  WLS 10.3.5 documentation provides more detailed information:

• How can I disable the mouse pad when you use a mouse plug-and-play?

  How can I disable the mouse pad when you use a mouse plug-and-play? I tried to disable the driver, and nothing works.

  Hello

  Check with support of the manufacturer system, documentation online or forums that there is probably
  Shortcut keys that enable and disable the touchpad functions.

  Parameters for TouchPad located in the control panel - mouse (there may be several tabs with TouchPad entered)
  and some come with a utility that loads in the Notification area next to the clock in the bottom right.

  ==========================================

  If necessary: (make sure that you have restarted at least once, if the above did not work)

  Panel of configuration manager devices - mouse and pointing devices - Double click on the touchpad - the driver tab-
  Click on update driver (it comes may not do anything like MS is far behind the drivers of certification), now right CLICK
  on the TouchPad and UNINSTALL.

  Then go to the USB and UNINSTALL ALL controllers except the category itself (all in). RESET

  This will refresh the driver for the TouchPad and battery USB. This does not prevent the touchpad from working.

  The similar procedure on XP, Windows 7 and Vista is the same, except that we need to clear the specific device if present.
  http://support.Microsoft.com/kb/310575

  Then go to the system manufacturer's website and get the latest touchpad drivers.

  Download - SAVE - go to where you put it-click on - RUN AS ADMIN.

  I hope this helps.

• HP Officejet J5780: Stripe yellow towards the bottom of the page when you use the document feeder

  When using the document feeder copy has a yellow stripe down page @21/8 "from the left margin. NO problem when using the tray.

  Hi @GlennG1 and welcome to the Forums of HP!

  I see that you have lines in the ADF.  I would like to help!

  I recommend to remove the ink cartridges and perform a power reset.  Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

  I also recommend this document:

  Good luck and please let me know the results of your troubleshooting operations. Thanks for posting on the HP Forums!
