• PersistentObject.getContents () returns null after app update

  Hello

  I'm trying to track down a bug with PersistentStore.
  Usually when I update the app I get the getContents() stored content.
  However, something in the code has changed from one version to the other and now getContents() returns null.

  I made sure the id has never changed for PersistentStore.getPersistentObject (id);
  I made sure that we use the same basic sdk (4.3.0)
  I made sure that there are the data stored in the stored hash table

  Currently, it's a hash table - no subclass (even though I know that I should change it to a subclass when it's fixed);

  I wonder if there are any suggestions on what might cause the getContents() return null - or which could result in the PersistentStore have cleared.

  What information is needed, please let me know and I'll paste.

  I found the problem after.

  Classes have begun to obscure differently. If the hash table was still readable, but because he could not read the content of the hash table, he would return null.

  It was unexpected, because if you have a custom class persisted and you try to read it, you will get the content, but you can't cast. But with the hash table, it does not return the content (uncastable) and it throws no exceptions...

  I hope this helps someone else who has a similar problem.

• VimClient.FindViewEntities returns null after a period of time

  Hi all

  I'm hosting a c# webservice in IIS that makes calls against our instance of vsphere to carry out certain functions.  A basic call is to get a list of all virtual machines.  Every so often, the webservice will get in a State in which the call returns a null value (we always have lots of virtual machines to the top):

  List<EntityViewBase> views = c.FindEntityViews(typeof(VirtualMachine), null, null, null);
  if (views== null) throw new Exception("List of VMs from VimClient.FindEntityViews is null!");
  

  At this point, I believe that this occurs if the Web service has not been restarted or recycled in some time.  Most likely, I'm storing the VimClient incorrectly.

  I'm caching of connection of VimClient in the following way.  My reason for doing this is so save time on calls (it takes about 20 seconds to call VimClient.Connect () to each webservice call, if I don't do this).

  (1) for Web service starts, I give the floor

  private static VimClient _vsphereClientConnection = null;
  _vsphereClientConnection = new VimClient();
  ServiceContent sc = _vsphereClientConnection.Connect(vsphereServerURL);
  UserSession us = _vsphereClientConnection.Login(vsphereUsername, vspherePassword);
  

  (2) I can enter this instance of the VimClient every time I need to perform a function at the instance of vSphere

  public static VimClient VSphereClientConnection
  {
   get 
  {
   Initialize.waitForInitialization(0);
   return _vsphereClientConnection; 
  }
  }
  

  where Initialize.waitForInitialization () checks if VimClient has completed the connection to vSphere.

  I cache this connection wrong?  Is there a better way to do this / a how to do it at all?  Or maybe I make a wrong assumption about why FindEntityViews returns null.

  I thought I could detect in the VSphereClientConnection property if the connection has expired in any way and re - connect, but it's not ideal because then the user must wait until the initialization again.  I'm also not sure how to check if the service is in bad shape without making a call that I know does not work in these States 'bad '.

  Thank you

  You can call SessionManager.sessionIsActive () to validate a session.  You could also do some other data requests.  Firewall between you and vCenter can sometimes drop idle connections (vCenter has a vpxd.httpClientIdleTimeout configuration value to increase or decrease and it should be higher that your firewall connection inactive drops).

  You can also simply cache the session ID (which is essentially in the cookie).  I don't know if the c# Toolbox has hooks to do this easily, however.  Perl, and it works very well in web servers.  The logic is get sessionID, attempting to load the existing session, in case of failure, try the new name of connection with the stored credentials.

• orgVdcNetwork.configuration.ipScope return null after upgrade to 5.1

  I'm currently testing my workflow because I upgraded my environment at 5.1.  It seems that orgVdcNetwork.configuration.ipScope now returns a null value for all of my orgVdcNetwork.  I was recovering information gateway and dns for use in my workflow of the ipScope.  I can't understand where that information went.  I tried it tears of the ExternalNetwork as well, and it's also coming back as null there.  I've rechecked in vCD and everything seems seems correct through the web administration tools.

  Paul

  Hello Paul,

  orgVdcNetwork and Exnternal networks are containing a list of ipScopes in vCD 5.1. In vCD to 1.5 was only a single ipScope.

  In order to get the ipScopes of orgVdcNetwork as a table, you can do:

  var ipScopes = orgVdcNetwork.configuration.ipScopes.ipScope.enumerate ();

  Enumerate() funtion replaces list table. If you have a single ipScope in the list, you can use it as
  ipScopes [0];
  Same thing can be applied to external networks.
  I hope this helps!

  Hello
  
  I just updated one of my instance of APEX of 3.0 to 3.2.1 version. After update I can't read session values using the function v (VARIABLE_NAME) of pl/sql. Always returns null (I tried v('session'), v ('app_id'), v ('app_user')).

• Need help with ics. SQL return null

  Hi experts WCS.

  I have this ics. SQL statement that returns an IList as null and nothing in the errStr in debugging print.

  IList rsATypes is ics. SQL (, sqlATypes, listName, limit, bCache errStr);

  The code is in one of my jsp. He ran very well in my local JSK (HyperSQL Db), but returns NULL in the case of Test (Oracle DB, if this is another).

  I got the sql statement println during execution and run it directly in Oracle DB (same instance) it returns the expected result set.

  The code snippet:

    System.out.println("## ics.GetSSVar(\"pubid\")          : " + ics.GetSSVar("pubid"));
  
      // Get Attribute Types
      String sqlATypes = "SELECT DISTINCT assetpublication.assettype "
                       + "FROM assetpublication "
                       + "LEFT JOIN approvedassets "
                       + "    ON assetpublication.assetid = approvedassets.assetid "
                       + "WHERE pubid = '" + ics.GetSSVar("pubid") + "' "
                       + "AND (tstate is null OR tstate <> 'A') "
                       + "AND (voided is null OR voided <> 'T') "
                       + "ORDER BY assettype; ";
      System.out.println("##0126 sqlATypes : " + sqlATypes);
      String from = "AssetPublication, ApprovedAssets";
      // String listName = null;
      String listName = "ATypesList";
      int limit = -1;
      // boolean bCache = true;
      boolean bCache = false;
      StringBuffer errStr = new StringBuffer("");
      ics.ClearErrno();
      IList rsATypes = ics.SQL(from, sqlATypes, listName, limit, bCache, errStr);
  
      System.out.println("## rsATypes : " + rsATypes);
      if (rsATypes == null) {
          System.out.println("## NO DATA in rsATypes! errStr : " + errStr.toString());
  

  }

  The journal:

  ## ics.GetSSVar("pubid")          : 1374097570685
  ## sqlATypes : SELECT DISTINCT assetpublication.assettype FROM assetpublication LEFT JOIN approvedassets     ON assetpublication.assetid = approvedassets.assetid WHERE pubid = '1374097570685' AND (tstate is null OR tstate <> 'A') AND (voided is null OR voided <> 'T') ORDER BY assettype;
  ## rsATypes : null
  ## NO DATA in rsATypes! errStr :
  

  
  

  I got enclosing try catch block, who did not take any exception.

  
  

  The funny thing is, in the same piece of code, an ics. Casea used already worked (which I noticed outside because there was not enough for what I want to do):

          StringBuffer errSB = new StringBuffer("");
          ics.SetVar("assetid", id);
          IList approvedAsset = ics.SelectTo("ApprovedAssets", "state,voided,tstate,locked,reason,treason", "assetid", null, -1, null, true, errSB);
  

  Any help/ideas from anyone would be really appreciated.

  Thanks Guddu1223, I discovered why.

  The SQL statement cannot end with a semicolon (see line 11 of my original above codes). Delete who had back all the records provided for in my resultset in the IList.

  Hello

  % ROWCOUNT SQL would return always 1 be the corresponding number of records would be 0 or infinite. This is because you do count (*), and she always get selected as a line. Let me know your condition of bussiness.

  In addition, you can try this it will give you the result you expect

    declare
       v_count          NUMBER;
    BEGIN
       v_count := 0;
       select count(*) into v_count

• ViewObject getCurrentRow() returns null for a particular VO

  1. I use JDeveloper 12.1.2 and see that one of the VO does not return a current line in the module of the application.

  Table of this VO has an another table foreign key relationship and corresponding EO mapping to a database table is defined.

  I defined the Association and link display to be able to make the key relationship foreign mapping.

  And moved VO belong to the corresponding data model of the parent object.

  However, getCurrentRow running on this instance of VO returns null.

  Runs the code SQL of VO same results as expected in the preview of the VO Editor.

  Can someone further comment on what might cause some getCurrentRow() which returns null despite the lines for VO that corresponds to its definition of SQL or Timo.

  2. one of the posts mentioned earlier setting the following will print the SQL used by VO in the console.

  AddVMOption - Djbo.deguboutput = console

  AddVMOption - Djbo.jdbc.trace = true

  However, my console does not show the SQL code as such to run executeQuery on VO.

  Can someone share your opinion on if these settings are changed in Jdev 12.1.2 charges.

  Thank you

  Rama

  GetCurrentRow() may return null if the vo is not used in the user interface. In this case, the pointer of the current line is set before the first row so that you can browse all lines.

  After execution of the vo, you must call premier() to get the first row, then next() to get the next line.

• Hash table returns null

  It's the stumping me. I add a key and a value in a hash table, pass in the key and retrieve the value. Basic enough, but when I go to retrieve the value a second time (after the restart of the application), it returns null.

  If it isn't exactly the code that would be the basic scheme:

  class A
  {
       private static Hashtable table = new Hashtable();
  
       public static Object getObject(Class clazz)
       }
            return A.table.get(clazz);
       }
  
       public static void setObject(Class clazz, Object obj)
       }
            A.table.put(clazz, obj);
       }
  
       //Code stuff...
  }
  
  class B
  {
       public static void main(String[] args)
       {
            A.setObject(C.class, new C());
            Object obj = A.getObject(C.class); //This works
       }
  
       //Code stuff...
  }
  
  class C
  {
       //Code stuff...
  }
  

  What happens on the 9550 Simulator and is fixed after restarting the Simulator but work always and only the first time through. If the app is closed, then reopened, then it returns null, even if the hash table was always the same items.

  Ah. When you run the application a second time, he rebuilt serializers to persistent store. Unfortunately, your objects of the class are new instances, so that they cannot be used as persistent hash keys. I suggest you use class names as keys rather than objects of class themselves.

  Do not apply to_date conversion sysdate . It's already a DATE value.

  It is the expected behavior. Some API calls can be used successfully since in a valid session of APEX. You can validate apex_item.date_popup query in the APEX SQL Workshop. Note that apex_item.date_popup2 is the recommended method because it shows a more modern jQuery calendar.

• Debugging inaccessible FacesException:Target, 'bean' returned null

  Hi all

  Jdev: 11.1.1.7.1

  We have a living ADF application that worked very well until installing a recent where a flow is the break with the message "inaccessible FacesException:Target, 'bean' returned null. It works very well in our UAT and our production environment is clustered.

  We were finally able to reproduce the problem in our local instance.

  Regarding the cause, the view behind the UI object, the research doesn't have the right keys. As a result, selection on the table was selecting two rows on the search results. By clicking on the commandlink, it seems that two events of Action are put in queue and after that the first action event navigates successfully, the second is pulled and fails.

  7u45 made a change that is not documented in the release notes. You must precede the properties with jnlp.myproperty in your JNLP file, unless your jnlp file is signed.

  But like me, since you can have different values in multiple deployments, signing the JNLP is impossible.

• apex_util.get_email returns null values

  Request Express 4.1.0.00.32
  
  I created a calculation for a page element to get the email of the user.
  
  The page is P16_EMAIL_ADDRESS.
  
  The calculation is a type of PL/sql. The code is:
  
  DECLARE
  L_EMAIL_RTN VARCHAR2 (240);
  BEGIN
  L_EMAIL_RTN: = APEX_UTIL. GET_EMAIL (p_username = > 'APP_USER');
  END;
  
  When I check the session information and debugging logs it indicates that the function is to return null.
  
  I figured I was doing something wrong in the APEX while I created a procedure in the database called the APEX_UTIL. GET_EMAIL. I've run in debug mode and saw that he too returned null. I get the same results with the GET_FIRST_NAME and GET_LAST_NAME functions.
  
  Can you see what I'm doing wrong? Or give an example of using these functions correctly?

  So if you know, APEX forums supports the use of the [code] and [code /] intended to set aside code segments for ease of reading.

  One thing I noticed in your sample service is this unconditional statement: RETURN NULL;

  Your function can do all sorts of things, but this indicates the function always return explicitly NULL - your behavior. You must declare a variable to store the results of the function call to APEX_UTIL. GET_EMAIL() and return this variable:

  create or replace function L_EMAIL_RTN
    return varchar2
   is
  declare
    v_email   VARCHAR2(240);
  begin
    v_email  := APEX_UTIL.GET_EMAIL(p_username => :APP_USER);
    return v_email;
  end;
