FileSystemRegistry.listRoots () will return NULL on BlackBerry 9300

I try to get the path the SD card in my blackberry application, and when I run this code:

sdCardPresent = false;
String root = null;
Enumeration e = FileSystemRegistry.listRoots();
while (e.hasMoreElements())
{
     root = (String)e.nextElement();
     if(root.equalsIgnoreCase("sdcard/"))
     {
          sdCardPresent = true;
     }
}

on device Blackberry 9300, the line Enumeration e = FileSystemRegistry.listRoots (); Returns a null value. I've tested this on two different 9300, both with SDCards, and the result is the same. The code works on other test equipment and simulators. Any experience this problem in the past?

Nevermind, I solved it. It was because I had the courage to try to debug actually on the device and have it connected to the computer. I pulled the plug and it worked.

  • Impossible to extract the LONG typed values; always will return null.

    I'm having a problem with ODP.net access to types of data LONG. I can't seem to find any way to access the data, it always comes back as an empty string - even when the same query is run in sqlplus or Developer SQL (from the installation of the client, hit the same user on the same target database) returns non-null results.

    My specific task is to strengthen our source control, but I can't retrieve the SEARCH_CONDITION values of the... ._CONSTRAINTS views.

    I reduced the tests to the following code:

    Sun DB = "~ a connection string works ~ ';
    OracleConnection conn = new OracleConnection (DB);
    Conn. Open();
    OracleCommand cmd = new OracleCommand ("select SEARCH_CONDITION from DBA_CONSTRAINTS where OWNER = 'SYS' and TABLE_NAME = ' UNDO$ ' and CONSTRAINT_TYPE ="C"", conn ");
    OracleDataReader dr is cmd. ExecuteReader();

    While (Dr. Read
    {
    String s1 = dr ["condition_de_recherche"]. ToString();
    String s2 = Dr. GetValue (0). ToString();
    String s3 = Dr. GetString (0). ToString();
    OracleClob clob = Dr. GetOracleClob (0);
    BLOB OracleBlob = Dr. GetOracleBlob (0);
    }


    None of the different types of data seem to help, all attempts at string returned as an empty string and attempts to clob/blob rise casting errors. It's probably worth noting that 'dr ["condition_de_recherche"] is DBNull' is set to false. It is not simply to retrieve a null and converted to an empty string.

    Please don't forget that it's hitting the SYS user, I just assumed that more people have a database with a SYS user installed as our particular schema :). I'm running a 10.2.0.4 hit a 10.2.0.3 installation of the client server.

    Any ideas? How can I get my check from the conditions of restraint via ODP.net?

  • Select list no display display value will return null instead

    I've been using selection for several of my applications list and something happens in this application that I can't identify. I have two select elements (with submit to point 3.2), Department and org (i.e., division). The user enters information about employees to the employee. If the Department is selected, the list of selection org is filled with only these associations related to the Department. Which works very well.

    The problem is...
    When information on the employees of the table is displayed (after it is registered, of course). the Department and org appear as "null", even if the line of database contains the correct data. It does not display the name of the Department and the division.

  • The body of the message to return null on os 4.5.0.18. When you use getBodyText()

    Hi all

    Today, when I debug my application on 4.5.0.18 device 8130.

    I implements FolderListener, when new messages coming,.

    I grap message object and want to analyze the body of the message to check if the message is what application you are looking for.

    Hoever, when I call Message.getBodyText (). It returns null.

    In fact, there a lot of message in the body of the message.

    is there any sweet experiencing this problem?

    What is work around?

    Thank you.

    getBodyText() will work on 4.5 If the body is 'plain text '. Otherwise, you will need to get the HTML content of the message and extract the text elements.

  • 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.

  • LocationProvider.getInstance always returns null

    I'm trying to run a slightly modified version of the application on a BlackBerry 7250 GPSDemo.

First one is locked to the O2 network and I can't use it with another sim card.  OK I'll try OS upgrade. Everything is good, now I have OS 6.0.0.380, when I'll try uprade '3' network BB I have problem. I can't upgrade, I know not why, me, my BB from '3' network have no updates, but my next BB 'O2' network have write...

    Please do not use foul language.

    Operating system device provided are "released" by specific carriers once that they are certified and trained to their support technicians, but still, you are able to load any carrier the same model by following the instructions below. Apparently '3' is not from the same upgrade as O2.

    See the link below to download and follow the simple installation instructions to install 6.0.0.668 in your 9300 OS.

    Make a backup of your device first, using Desktop Manager > backup. Close the office at the end Manager.

    1. download the OS files to the PC then install on the PC by running (double click) the downloaded file.

    https://swdownloads.BlackBerry.com/downloads/contactFormPreload.do?code=D840CC5D906C3E9C84374C8919D2...

    2. go in c:\program files Research in motion\apploader and delete the file named "vendor.xml."
    3. plug in the BB and double-click on "Loader.exe." It is located in the same place as the above vendor.xml file.

    Note: Some users may be concerned they will void their warranty of device by loading an OS from another carrier. There is really nothing to fear. Please read more information about it here: http://www.port3101.org/power-users/296-blackberry-os-upgrade-including-betas-myths-dispelled.html

  • DataBind method call returns null in the WebCenter content filtering

    Hello

    I got code that has a problem and I am new to the WebCenter content and filters that can be added. We have a FileNameFilter class that begins with the code

    / public class CWEFileNameFilter implements FilterImplementor {}

    public CWEFileNameFilter() {}

    Super();

    }

    public int doFilter (workspace workspace, DataBinder dataBinder,

    ExecutionContext executionContext) throw {DataException

    Service string = dataBinder.getLocal ("IdcService");

    ....

    }

    }

    However, service is sometimes return null and then filter throws a NPE.

    My questions are:

    (1) can we explain what dataBinder.getLocal ("IdcService"); is done and why it might come back as null

    (2) anyone can provide links to documentation that explains the filters and a little more on the object DataBinder as the JavaDoc is not much help.

    Thank you
    Marc

    Hi Marc,

    Below the code will give the name of the service for which the filter is implemented LocalData

    Service string = dataBinder.getLocal ("IdcService");

    for example below

    This example displays the entire response including localdata data and results that are created in the execution of the service. Here is the code snippet

    Under blog will give an idea about the filter but the best place to learn or start is "The Definitive Guide to Stellent Content Server Development" by Brian Huff

  • 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.

  • 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.

  • iter.getRowSetIterator () .getPixel (key) always returns null

    Hello

    I use jdev 11.1.2.2.

    I'm trying to get the rank of an iterator to view using the key object
                for (int i = 0; i < selectedCategory.size(); i++) {
                        Key key;
                        Object[] keyValues = new Object[2];
                        keyValues[0] = getCurrentAssetCategoryId();
                        keyValues[1] = getSelectedCategory().get(i);
                        key = new Key(keyValues);
                        Row row = iter.getRowSetIterator().getRow(key);// Keeps returning null even though the value is present in the view object
                       row.setAttribute("Attribute", "value");
    No idea why this is happening?

    Thanks in advance,
    Rakesh
