  with old java version, System.getProperty ("myproperty") works very well to return the value, but with u45 it returns null.

  Does anyone have the same problem? no idea how to fix or work around it?

  Thank you

  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.

  I tried to submit a bug on this issue report, but their bug report process works as well as 7u45...

• Problems capturing pictures about OS6 - East System.getProperty ("video.snapshot.encodings"); valid?

  Hello

  I hope someone can help with this query.

  I use the code that is very similar to the sample application camerademo to take a photo using the camera. It works properly on devices running OS5. However, on devices running OS6 photo is just an image of white/black.

  I think I followed the problem until the encoding string passed to getSnapshot(). When I switch which must be a valid encoding string (based on the output of System.getProperty ("video.snapshot.encodings")) the captured image is a black screen. However, when I pass null to getSnapshot() it works correctly. I want to avoid using null as the captured image is much more that I need and for reasons of effectiveness, I would like to avoid having to reduce its size after the capture of the photo.

  I tested this on the 9780 Simulator. The corresponding code is included below for reference.

  Thanks in advance!

  It turns out that it was only a problem on the Simulator. I managed to get my hands on a real device 9780 and the code works fine on it.

• System.getProperty

  I'm trying to access the SD card on the Simulator.

  I first 'change' SD card via the Simulation menu and specify a path name, that I have set up to be identical to the structure of the directory of the SD card.

  Then, something I just found out, is that I have to get the name of the SD card.

  System.getProperty tried to get the name of the root directory, and I got the following results.

  The key string result

  filecon.dir.MemoryCard null

  filecon.dir.MemoryCard.Name null

  Why do I get null for the name of the name of the SD card?

  How to open a file on an SD card on the Simulator is - a. Is there anything else I need to put in place on the Simulator in addition to change SD card.

  .. .where is this result telling me that the way to access the Blackberry directory on the SD card is to use the following:

  file:///BlackBerry/

  that is the SD card has no name... null?

  Thank you

  -Donald

  I solved this myself (at least this part :-)

  OK, for those of you who want to know how to open your media card correctly (at least in the storm).

  First, make a call to System.getProperty ("fileconn.dir.memorycard");

  This returns the string "file:///SDCard/".

  Note that you are not guaranteed that the file system of the media card will always be SD card, so you should always call System.getProperty beforehand.

  Then, if you use the Simulator, you must select the simulate change... SD card menu. This opens a small window allowing you to select different directories (by default is set to None, which means the media card is disconnected). You can click new folder to set the directory that emulates the directory root of the press card. You can enter several directories and it will remember them so you can switch from one to the other. The entry selected (highlighted) is used, so if you select none, it generates an event to remove media card.

  You must also set the it strategy using strategy-simulation game IT... menu.

  Under the tab control application, you must assign to allow local connections and all the other features that you will use. Similarly, the policy of COMPUTER you must select allow local connections and click on him-> the button to add to the list of policies. Also you must click on the set after that to define the it strategy.

  OK, now you can open the connection to the file.

• 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.

• LocationProvider.getInstance always returns null

• 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.

  The reason why it works in my local, but not stable instance that I guess is my local JSK + HyperSQL, in WCS + Oracle DB instance trying...

• ViewObject get attribute always returns null

  Hi guys,.

  I need your help, I'm going crazy.

  I'm just trying to browse a ViewObject as I did a thousand times but despite getEstimatedRowCount return 1 and the Row inside the SENTENCE object is not null, getattribute always returns null, does not care if I call getAttribute (String) or getAttribut (int)

  This is the last code I tested:

  AppMod = (PeopleFinderAppModuleImpl) this.getApplicationModule () PeopleFinderAppModuleImpl;

  PfUserGetInfoImpl pf_Info = (PfUserGetInfoImpl) appMod.getPfUserGetInfo1 ();

  pf_Info.setp_userid (UserID);

  pf_Info.executeQuery ();

  System.out.println ("# view getEstimatedRowCount:" + pf_Info.getEstimatedRowCount ());

  PfUserGetInfoRowImpl r = null;

  RowSetIterator rsIterator = pf_Info.createRowSetIterator (null);

  While (rsIterator.hasNext ()) {}

  r = (PfUserGetInfoRowImpl) rsIterator.next ();

  System.out.println ("# AttributeCount:" + r.getAttributeCount ());

  String [] uploading = r.getAttributeNames ();

  for (int i = 0; i < attrs.length; i ++) {}

  System.out.println (I + "" + uploading [i] + "=" + r.getAttributeValues () [i]);

  }

  }

  rsIterator.closeRowSetIterator ();

  The output is:

  # userid: EPETRANG

  # Discovers getEstimatedRowCount: 1

  # AttributeCount: 13

  0 Userid = null

  1 name = null

  2 Givenname = null

  3 family name = null

  4 title = null

  5 Dn = null

  6 mail = null

  7 company = null

  8 Department = null

  9 Telephonenumber = null

  Mobile 10 = null

  11 Ipphone = null

  Manager of 12 = null

  My Env record:

  Build JDEVADF_11.1.1.7.0_GENERIC_130226.1400.6493

  1.6.0_45 64-bit JVM

  Of course, the query returns 1 row SQLDeveloper and ApplicationModule compressiometre is as well.

  You see something wrong in the code? I tried to delete and re-create the ViewObject without a bit of luck.

  Hi guys,.

  Thanks to you all.

  This morning I just tried to delete and recreate the Weblogic JDev field and now everything works fine. Looks like that integrated weblogic has been screwed

  Thanks again.

• HttpServletRequest getParameter returns null in Jdeveloper 11 g

  Hello:
  
  IM currently involved in a project to the title of the ADF faces in Jdeveloper 11 g. I have a requirement that an online application must be connected to a bank. We can redirect the workflow on the site of the Bank, but the return parameters are the problem. The Bank sends the confirmation by MAIL, but when we try to get the data to a ControllerBean using a HttpServletRequest parameters return null.
  
  This works very well in the Adf using Oracle Jdeveloper 10 g but in Jdeveloper 11 g Adf in richfaces don't.
  
  Here are the facts:
  
  1. a third application must send parameters via post method in the form of html to my request.
  
  2. in the PrepareModel of the support of my jsp bean, I get the HttpServletRequest object.
  
  3. I have access to the settings in the HttpServletRequest.
  
  Here's the pararameter sending form example:
  
  < html >
  < head >
  < meta http-equiv = "Content-Type".
  Content = text/html"; charset = windows-1252 "/ >"
  < title > < /title > answer Bank
  < script languaje = "JavaScript" type = "text/javascript" >
  function responder() {}
  document. TestForm.Submit ();
  }
  < /script >
  < / head >
  < body >
  < name of the form = "testform" action = "myAppUrl" method = "post" >
  < input type = "hidden" name = "parameter1" value = "Value1" / >
  < input type = "hidden" name = "parameter 2' value = 'value2' / >
  < input type = "hidden" name = "parameter3' value = 'value3' / >
  < / make >
  < / body >
  < / html >
  
  
  The code I use in the bean of the JSP (HttpServeletRequest get parameters):
  
  
  public void prepareModel (LifecycleContext context) {}
  super.prepareModel (context);
  ADC ADFContext = ADFContext.getCurrent ();
  FacesContext facesContext = FacesContext.getCurrentInstance ();
  try {}
  HttpServletRequest request =.
  (HttpServletRequest) facesContext.getExternalContext () .getRequest ();
  System.out.println (Request.GetParameter ("Parameter1")); / / < < < < < ME GIVES a NULL VALUE
  System.out.println (Request.GetParameter ("parameter2")); / / < < < < < ME GIVES a NULL VALUE
  System.out.println (Request.GetParameter ("parameter3")); / / < < < < < ME GIVES a NULL VALUE
  } catch (Exception ex) {}
  ex.printStacktrace ();
  }
  }
  
  Any advice?
  
  Concerning

  Hello

  on the f: view of the JSPX page element, set the afterMethod property to point to a managed bean method. In this method of bean management, determine the phase and if this phase is afterRestore, read the query parameter, if it exists (be sure to check if the setting exists). If the parameter exists, write on a range of memeory as viewScope or session. Then when you need this setting in the managed bean, get it from the scope of the memory

  Off topic:
  Where the code tags? I can't find it here.

  as far as I can see, your person class is not a managed bean. I expect an annotation @ManagedBean (name = "thePerson") on it. If you do not a managed bean, JSF doesn't know it exists.

  If you don't want a person as being a managed bean, then simply yourself create an instance of your class MBTest.

  private Person thePerson = new Person();
  

• getAttribute() method of a view object returns NULL

  Hello
  I am currently implementing PPR in one of my OFA page and I took the following approach.
  
  I stated the Boolean attribute transitional follwing in the VO() outside of the existing attribute 'sense '.
  1 MfgEnttity
  2 MfgAcct
  3 MfgSubAcct
  4 MfgCc
  5 MfgProj
  
  In the page I used these attributes in the property made in the form "${oa." XXR2RMfgproSegVO.MfgSubAcct}' like that.
  
  Now, in the central, I wrote the following code.
  
  ' Public Sub processRequest (pageContext OAPageContext, OAWebBean webBean)
  {
  super.processRequest (pageContext, webBean);
  OAApplicationModule am = pageContext.getApplicationModule (webBean);
  am.invokeMethod ("initializeXXR2RMfgproSegVO");
  }
  ' Public Sub processFormRequest (pageContext OAPageContext, OAWebBean webBean)
  {
  super.processFormRequest (pageContext, webBean);
  
  Event string = pageContext.getParameter (EVENT_PARAM);
  Source of the string = pageContext.getParameter (SOURCE_PARAM);
  Am = (OAApplicationModule) pageContext.getApplicationModule (webBean) OAApplicationModule;
  am.invokeMethod ("handleSegmentChangeEvent");
  }
  }
  
  
  And the AM code is as follows:
  
  Public Sub initializeXXR2RMfgproSegVO()
  {
  OAViewObject vo = getXXR2RMfgproSegVO();
  If (!) VO.isPreparedForExecution ())
  vo.executeQuery ();
  Line = vo.createRow ();
  vo.insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  }
  
  Public Sub handleSegmentChangeEvent()
  {
  PVO OAViewObject = (OAViewObject) findViewObject ("XXR2RMfgproSegVO");
  OARow hdrRow = (OARow) pVO.getCurrentRow ();
  String status = (String) hdrRow.getAttribute ("Meaning").
  System.out.println ("poRow" + hdrRow.toString ());
  System.out.println ("value of the State is" + status);
  If ("Entity". Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.TRUE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ("Account". Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.TRUE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ("Subaccount". Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.TRUE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ("cost Center".equals (status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.TRUE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ('Project'. Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.TRUE);
  }
  on the other
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  }
  }
  }
  
  Now when I change in the value of the attribute "Meaning" page that he can always get into the else part, which is where all the attributes are 'False'.
  
  The two System.out.Println statements return the following values.
  
  03/10/22 15:41:08 poRow xxr2r.oracle.apps.gl.coam.poplist.server.XXR2RMfgproSegVORowImpl@3
  03/10/22 15:41:08 state value is null
  
  Can you please why this 'status' returns NULL and how I can get the current selected line in the page?
  
  Thank you
  Lucile

  Hello

  you set the attributes of PVO, based on a condition, your old code is just the question is from where you can get the status, you may get this page, but you must pass this value to AM.

• BC4J: EntityAssociation.getSourceEnd () .getDBObjectName () returns null

  Dear forum,
  
  I use JDeveloper 10.1.3.4.0.4270 with 10.1.3.42.70 ADF business components.
  
  This is what I call inside the validate method of a class that extends EntityImpl.
  

      
  
      private void test(){
  
          EntityDefImpl entityDefImpl = this.getEntityDef();
  
          AssociationDefImpl[] associationDefImpls=entityDefImpl.getAssociationDefImpls();
  
          for(int iter=0;iter<associationDefImpls.length;iter++){
  
              AssociationDefImpl associationDefImpl=associationDefImpls[iter];
  
              EntityAssociation entityAssociation=associationDefImpl.getEntityAssociation();
  
              System.out.println(entityAssociation.getSourceEnd().getDBObjectName());      // null
  
              System.out.println(entityAssociation.getSourceEnd().getName());        
  
              System.out.println(entityAssociation.getDestinationEnd().getDBObjectName()); // null
  
              System.out.println(entityAssociation.getDestinationEnd().getName());
  
          }
  
      }

  My problem is that getDBObjectName() always returns null, while getName() returns what it should be, and, otherwise, everything looks beautiful and functional as it should.
  
  I guess I'm doing something wrong here. So, how could I, in implementation of the entity, its associations list and search the database of the names of tables?
  
  Thank you for your help,
  
  ADSM

  Try:

  System.out.println(((EntityDefImpl)entityAssociation.getSourceEnd().getOwner()).getSource());
  System.out.println(((EntityDefImpl)entityAssociation.getDestinationEnd().getOwner()).getSource());
