• ADF: How to manage the value zero when downloading the csv file

  Dear all,

  I'm new in the ADF and use 12.2.1. I am downloading of data in the database using af table: inputfile and CSVParser class. Data download correctly in the database where all columns are met, but whenever the csv file has value null (empty) in his column, then CSVParser class does not recognize it and get the next value of columns and assign the previous column. I also tried another one that uses a different class to download date but not get success.

  For Ex:

  ID name Dept

  1 abc Dept1

  2 cde Dept2

  3 Dept3

  In example above two first line are perfectly inserted in the table while the third line Id goes to ID column, due to the value of the column name is null class CSVParser does not recognize it and put Dept3 in the name column.

  Please help how to handle this.

  Thanks in advance.

  Kind regards

• How to manage the plsql error occurring in the exception block

  We know how to manage exceptins located in the BEGIN block.
  But I am unable to catch the exception in the exception block. Write an erroeneous code so that the control will go to the exception block and there is also a plsql error, but I am unable to handle that error, it returns the error to the calling environment.
  
  DECLARE
  CNT NUMBER (5): = 0;
  
  BEGIN
  
  Select "Chris" IN double's NTC;
  DBMS_OUTPUT. Put_line (to_char (CNT));
  
  EXCEPTION
  WHEN invalid_number CAN
  DBMS_OUTPUT. Put_line (' error occurred inside the start block ');
  
  CNT: = "deba";
  
  WHILE OTHERS THEN
  DBMS_OUTPUT. Put_line (' error occurred inside the start block ');
  
  END;
  
  Please suggest me how to catch this exception?

  Hello

  DECLARE
  CNT NUMBER (5): = 0;

  BEGIN

  Select "Chris" IN double's NTC;
  DBMS_OUTPUT. Put_line (to_char (CNT));

  EXCEPTION
  WHEN invalid_number CAN
  DBMS_OUTPUT. Put_line (' error occurred inside the start block ');

  CNT: = "deba";

  WHILE OTHERS THEN
  DBMS_OUTPUT. Put_line (' error occurred inside the start block ');

  END;

  First of all your exception mouhamadou who you have sent i.e. invalid_number itself does not.
  You should use named exception VALUE_ERROR to catch the exception in the main block.

  SQL> DECLARE
    2  cnt NUMBER(5):=0;
    3  BEGIN
    4  select 'debalina' INTO cnt from dual;
    5  DBMS_OUTPUT.PUT_LINE(to_char(cnt));
    6  EXCEPTION
    7  WHEN Invalid_number THEN
    8  DBMS_OUTPUT.PUT_LINE('error has occured inside main block');
    9  end;
   10  /
  DECLARE

    9  end;
   10  /

  Your doubts regarding catch the exception in the exception block, you can run as below, by nesting a block Begin in the exception block itself.

  SQL> DECLARE
    2  cnt NUMBER(35):=0;
    3  BEGIN
    4  select 'debalina' INTO cnt from dual;
    5  DBMS_OUTPUT.PUT_LINE(to_char(cnt));
    6  EXCEPTION
    7  WHEN Value_error THEN
    8  DBMS_OUTPUT.PUT_LINE('error has occured inside main block');
    9  Begin
   10  cnt:='deba';
   11  Exception
   12  WHEN OTHERS THEN
   13  DBMS_OUTPUT.PUT_LINE('error has occured inside exception block');
   14  End;
   15  END;
   16  /
  error has occured inside main block
  error has occured inside exception block

• [ADF, JDev12.1.3] How to manage cookies (configure/create/read) in the ADF applications?

  Hallo,

  I would like to create a cookie in my ADF application.

  To start I used the code shown in this thread code example for create / read a cookie value? but the cookie seems to not be created.

  It is not present in Firebug or it can be retrieved by the code.

      Cookie userCookie = new Cookie("myCookie", "hello");
      userCookie.setMaxAge(-1);
      FacesContext ctx = FacesContext.getCurrentInstance();
      ((HttpServletResponse) ctx.getExternalContext().getResponse()).addCookie(userCookie);
  
  
      Cookie retrieveCookie = (Cookie) ctx.getExternalContext().getRequestCookieMap().get("myCookie");
      if (retrieveCookie != null)
        System.out.println("My cookie is: " + retrieveCookie.getName() + " " + retrieveCookie.getValue());
  

  What's not in the code?

  There may be something to confiure in the application of the ADF?

  Thank you

  Federico

  1. Cookie userCookie is new Cookie ("MyCookie", "Hello");.
  2. userCookie.setMaxAge(-1);
  3. FacesContext ctx = FacesContext.getCurrentInstance ();
  4. (Ctx.getExternalContext () m:System.NET.FtpWebRequest.GetResponse ()) .addCookie (userCookie) (HttpServletResponse);
  5. Cookie retrieveCookie = ctx.getExternalContext () .getRequestCookieMap () .get ("myCookie") (Cookie);
  6. If (retrieveCookie! = null)
  7. System.out.println ("my cookie is:" + retrieveCookie.getName () + "" + retrieveCookie.getValue ());

  Is - this code is run from the same method in java?

  If this will not work (cookie is added to the http response if you can't get this until the next http request arrives)

• How Pix manages the rare IP protocol packets

  Does anyone know of a document explaining how the Pix handles, regarding the State, rare IP protocol packages such as ESP, AH, OSPF, GRE, etc. ? I'm concred with traffic flowing through the pix is not intended.

  I understand how TCP, UDP, and ICMP packets are handled, but I can't find anything on all others.

  Thank you.

  In General, the Pix must inspect any protocol passes through it accepts for TCP and UDP. The exception is a protocol which is managed by a '' correction '' like PPTP which has a correction to allow GRE (Protocol 47) traffic that results.

  If you want a different protocol than UDP/TCP to be allowed to get THROUGH, you almost create an ACL entry for her.

  The other exception is the traffic to the Pix itself as host. ACL have absolutely no effect on the traffic to the Pix as the host. For example, the packets OSPF intended for the Pix when running OSPF. Or packages ESP for the Pix for a VPN tunnel, it stops. Or ICMP traffic to the Pix itself (controlled using the command [icmp]). ACL don't apply to transit traffic.

• How to set programmatically the current node in a tree view of the ADF.

  Hello
  

  I'm trying to understand how to set programmatically the current node in a tree view of the ADF.

  My use case example is quite simple; If we take the sample application ADF Summit where under Management Summit, we have a tree view on the left with a list of high level of the country which in turn contain a subset of customers; then, in the right pane, we the customer detail information.

  What I'm trying to achieve is a solution by which I can add a new customer, commit and then to the tree show the client newly created as the currently selected entry.

  I use a pop-up dialog box to create my new entry of the customer and everything works well in this area, and my newly created folder is saved in the database.

  I know how to force the tree to cool off, but what I can't understand is how to do so, it highlights the newly created folder.

  Any help would be much appreciated.

  If you haven't done so already, take a look at the action of com.vmware.libarary.soap.processOutParameters.  It is the action that generated the log you have placed in us.  It generates an object Properties (key, value pairs) with the value for each setting that results.

  In your case, assuming that 'outProps' is the result of the above, you can use:

  var getRequestStatusResult = outProps.get ("GetRequestStatusResult");

  And to analyze the code XML with E4X as Ilian said.

• How to successfully deploy a library shared the ADF?

  I have created a library that depends on the length of JSP, JSF 2.0, ADF Model DURATION etc., JSTL 1.2. When I try to use a class of this library in an application, (I added a ref library to weblogic application. The app XML) I get the following error:

  >java.lang.NoClassDefFoundError: org/apache/myfaces/trinidad/model/RowKeySet

  How am I supposed to properly deploy my library / specify dependencies, so that weblogic server might find them? MANIFESTO. MF in the container of the library, made by JDeveloper, contains only the manifest-Version headers and hand-Class.

  Under subsection 38.2 in the Guide Oracle® Fusion Middleware Fusion developer Oracle Application Development Framework 11 g Release 2

  > If you are packaging a component with dependent jars, such as third party jars, you have two options:

  > 2. If using Extension Library JDeveloper is not possible, you can place the dependent jars in the same location as the ADF library JAR and include an entry manifest classpath for each person dependent > JAR.

  I hope that I don't need to include all the pots to jsf/adf/bc4j in the container in my library, I do?

  Well, I finally managed to make it work. You need a war with the shared library jar under WEB-INF/lib, and then reference it in the application weblogic.xml.

• How to find the ADF version used in a deployment archive?

  Hello
  
  When I get an ear/war file from a developer I want to deploy on a Weblogic Server it would be nice to be able to verify that the ADF version developers used is the same that is installed on the server.
  
  I tried to look at different deployment files but I can't find anything about it. Can anyone help?
  
  I can see the JSF version but noting on ADF.
  
  What about Peter

  I see your problem but do not see how you can get the information of just the EAR file as long as it is not put there by purpose. The required information is part of the jars that are installed on the servers. They are not part of the ear, but are only referenced.

  For the server side, I've written a web service that I install on each server (managed server that runs to the ADF, run time). This service at least tell me the version installed on the server. You can find the service including the source to my blog http://tompeez.wordpress.com/2012/02/05/adf-how-to-find-out-which-adf-version-is-installed-on-a-manged-weblogic-server/.

  There was a discussion on this forum and the ADFEMG google Group discuss how to know what the newer version (from sources of a project) was used to develop the App. Unfortunately, today you can't get a definitive answer to this. There is an ER out for it to allow in the future (http://java.net/jira/browse/ADFEMG-70).

• How can I default first line below the selected line in the table of the adf

  Hello
  
  I use Jdeveloper 11 g,
  I created Adf quick query with table and changed selectionListener table as #{CustRMMap.onRMGroupNameChange}.
  and when I click on find fast query no row is selected.
  I want the first row to be selected / highlighted by default when I click search.
  
  Patel Imran

  You can also set an attributeValue in pagedef.xml
  bind this attributeValue with column of your table. This sets the value of the selected line to the variable attruibute.
  Will now link this with your desired component attributeValue.
  Put partial trigger on the component that should display this value.
  This will save you to write custom code and use the default table selection listener property, which marks the first default line.

  Apart from this, if you want to govern the first default line of managed bean selection use this code...

  + _Table = selectionEvent.getSource ((richeTableau)) richeTableau; + *
  + / / the model in the Collection is the object that provides the structured data.
  + / / for rendering table +.
  + TableModel CollectionModel = table.getValue ((CollectionModel)); + *
  + / / the ADF object that implements the CollectionModel is JUCtrlHierBinding. IT +.
  + / /is wrapped by the CollectionModel API.
  + JUCtrlHierBinding adfTableBinding = tableModel.getWrappedData ((JUCtrlHierBinding)); + *
  + / / Acess the iterator ADF, binding that is used with the binding table ADF +.
  + DCIteratorBinding tableIteratorBinding = adfTableBinding.getDCIteratorBinding (); + *

  + / / the role of this method is to synchronize the table feature selection +.
  + / / with the selection of the model of the ADF +.
  + Object selectedRowData = table.getSelectedRowData (); + *
  + / / cast of JUCtrlHierNodeBinding, which is the subject of the ADF that is +.
  + / line/a +.
  + JUCtrlHierNodeBinding nodeBinding = selectedRowData (JUCtrlHierNodeBinding); + *
  + / / get the key of the node binding line and set it as the current line in the +.
  + / / iterator +.
  + Key rwKey = nodeBinding.getRowKey (); + *
  tableIteratorBinding.setCurrentRowWithKey (rwKey.toStringFormat (true)); + *

  and another way on the right is a custom like this code:

  + public void setDefaultRow (int count) {/ / call this method your method of selection custom, rom pass the line of the line to select index. count = 0, will select first row + *}

  + try {+ *}
  Object oldRowKey = tblMag.getRowKey (); *
  + try {+ *}
  This.

  .getSelectedRowKeys () .clear ();*
  * +} catch (System.Exception e) {+ *}
  System.out.println (e.getMessage ()); *
  +}+
  This..setRowIndex (count);*
  RKS RowKeySet =. getSelectedRowKeys();*
  (RKS). Add(. getRowKey());*
  RKS =. getSelectedRowKeys();*
  +.setRowKey (oldRowKey); +
  * +} catch (System.Exception e) {+ *}
  System.out.println ("error:" e.getMessage ()); + *
  +}+
  +}+

• How/where to store more information page in the ADF?

  Hi all
  
  What is the best way to fill the managedBean during the loading of the page?
  
  In my application, I have a page fragment that displays the details of the user of Webservice DataControl. I have and drag the data to the pageFragment webservice control. This fragment has mapped in the taskFlow and the annex taskFlow in to JSPX homepage as a region. I need to store such user information in any place (ManagedBean / or any other better place to store) that I can use at my request along, because I won't run again whenever the webservice to get the same information from the user. Also, I want to collect and store this information while I give back to the homepage, not after any action of the user.
  
  Please advice how & where to store the information in the ADF? Can I create a managedBean? If so, how to trigger this class method on page load?
  
  Thank you
  KLN

  Hello

  in this case, you configure the managed bean to be within the scope of the session. Then, on the first page, you set a stage for restoration after phase listener (it is a beacon in the f: view element). This is phaselistener refers to the bean managed using EL (important). She can do by using an expression of the method in JSF. For example, if the managed bean had a populateUserInfo method then yu might reference #{beanname.populateUserInfo} and run the expression of the method using Java. In the managed bean, the method would be to access the link layer using the BindingContext class

  http://download.Oracle.com/docs/CD/E15051_01/apirefs.1111/e10653/Oracle/ADF/Model/BindingContext.html

  Call

  . GetCurrent () .getCurrentBindingsEntry () BindingContext to get a handle of instance active BindingContainer.

  BindingContainer links is BindingContext.getCurrent () .getCurrentBindingsEntry ();.

  Then on the container of the binding, you call the method to query the Web Service for the modules

  before calling a method on the ADF link layer, make sure that the ADF is binding for the method
  OperationBinding opws (OperationBinding) = bindings.get ("name of the method exposed on the other side");
  If you need pass parameters
  opws.getParamsMap () .put ("name of the argument", value);
  OPWS. Execute();

  You can use similar code to access the information of the user of the iterator method in the ADF to complete managed bean fields. You can access user information from the bean managed through getter and setter methods
