• DataOutputStream HTTP Post rinse and segment the encoding problems

  Hello

  I'm finally back to the question that I had a few months ago, but I can't always solve this

  I used this article to understand how to upload files into pieces of a server: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/800431/How_To _...

  Downloading is easy to implement, but I have problems with the download. I am trying to download a large file into smaller pieces. I tried different options. The one that works best is when I use DataOutputStream and write in there after each small party has been read from the file.

  But when I used the flush() function then he threw OutOfMemoryException()! But only if the file is quite large.

  An example of code:

  InputStream    is = (StreamConnection)Connector.open(url , Connector.READ_WRITE, true);
  HttpConnection c = (HttpsConnection)is;
  
  //set connection parameters
  c.setRequestMethod( HttpConnection.POST );
  c.setRequestProperty( "User-Agent", "MyUserAgent/0.2" );
  
  for( ;; )
  {   if( done ) break;
  
     //i have removed some reading code to simlify example
     out.write( bytedata  , 0 , bytesRead );
     Thread.yield();
  }
  
  out.flush();     //<-- OutOfMemory exception here!
  
  int result = c.getResponseCode();
  
  out.close();
  

  I found that I wasn't the only one to have this problem.

  2: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5026745

  I usually have the same code, but only use HTTPConnection for this.

  The solution was to use "Chunked" encoding of the header and appellant hunting every time data is written to the output stream.

  However, it has not worked for me. If I use a stored block coding, I 'ConnectionClosedException' when flush() is used for the first time.

  Here is a code example:

  InputStream    is = (StreamConnection)Connector.open(url , Connector.READ_WRITE, true);
  HttpConnection c = (HttpsConnection)is;
  
  //set connection parameters
  c.setRequestMethod( HttpConnection.POST );
  c.setRequestProperty( "User-Agent", "MyUserAgent/0.2" );
  c.setRequestProperty( HttpProtocolConstants.HEADER_TRANSFER_ENCODING, "chunked" );
  
  for( ;; )
  {
     if( done ) break;
  
     //i have removed some reading code to simlify example
     out.write( bytedata  , 0 , bytesRead );
     Thread.yield();
     out.flush();     //<-- ConnectionClosedException
  }
  
  int result = c.getResponseCode();
  
  out.close();
  

  Here is a screenshot of the at the time of the exception stack trace:

  

  And here are the details of the exception:

  

  Now, I honestly don't know what to do next. I tried all sorts of options and choices, but can not get this to work for some reason to download any.

  Tried on BlackBerry JDE and Simulator 4.2.1

  Help, please

  Thank you.

  Thank you, but I think that this was not related to this problem.

  The solution is to use SocketConnection would work on writing data OutputStream and flush(). But only if the Content-Length is calculated with precision and this server application is also properly formatted.

  If there are errors in the POST request, the server would send a message back and ConnectionClosedException appear.

  The best way to resolve these issues is to get a sniffer package good as "Wireshark" and study all the packages with a lot of attention even a small typo can break everything.

  I have another question, but the download itself works with the function flush() as expected on the device and emulator. So I think this can be considered fixed.

• Problem with large XML files over HTTP segmented analysis

  I am trying to isolate a bug introduced when the JRE in Java 7u51 use 7u71 without changing the codes. The problem seems to be very similar to: Bug ID: JDK-8027359 XML parser returns incorrect results of analysis.

  Further investigation showed that it was also introduced in the same versions (7u71) where this patch has been applied. Unlike this bug, my XML is marked as version 1.0. He also seems to be with only large XML, the order of 10 MB files or more.

  Is the closest I've been able to reduce it down to the code uses JAXB to disrupt a flow which tells me that the debugger is an org.apache.http.com.EofSensorInputStream / org.apache.http.impl.io.ChunkedInputStream. The exception I get is not consistent, but usually appears from pieces are replaced or mixed, with result the letters appearing in the attributes that are actually numbers, or like the following, where an attribute "testAttribute" gets partially crushed by the end of a timestamp that was in another section of the XML file.

  javax.xml.bind.UnmarshalException
  - with linked exception:
  [javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,98748]

  A code here which seems to reproduce if you can connect to an XML server that returns a large segmented XML file:

    SchemeRegistry registry = new SchemeRegistry();
    registry.register(
                  new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
    HttpClient client = new DefaultHttpClient(new BasicClientConnectionManager(registry));
    String url = "http://someUrlReturningAlargeChunkedXML";
    HttpGet method = new HttpGet(url);
    HttpResponse response = client.execute(method);
  
    InputStream inputStream = response.getEntity().getContent();
  
    XMLStreamReader responseReader = factory.createXMLStreamReader(inputStream);
    JAXBElement<JaxBObjectOfResponse> wot = unmarshaller.unmarshal(responseReader, JaxBObjectOfResponse.class);
  
  
  

  There is no error if you connect using URL.openStream () to the same service. If I read bytes directly and write to a file, there is no error. The error occurs only when I try to disrupt it is great and I use Java 7u71 (or later). It can be constantly repeated with the jsp webapp I use, but did not show the error when I used the same code with a Wikipedia dump XML file.

  How can I unmarshal differently to avoid this problem? Or, how can I best isolate the bug so it can be sent to the appropriate bugs system?

  Seems to be related to this bug, which will be fixed in 7u80 and others (in April?).

  http://bugs.Java.com/bugdatabase/view_bug.do?bug_id=8059327

  Tests with the final version in early 7u80 showed it fixed my related question.

• BUG? Presentation of elements via Dynamic Action in Internet Explorer generates "null."

  I first noticed this using the newly improved apex.oracle.com. When I have dynamic action that must send the values of page element and the value is null / empty, the call to post/ajax result includes the literal 'null' as the value for this parameter.
  
  for example
  p_flow_id = 65928 & p_flow_step_id = 2110 p_instance = 574862348021401 & p_request = FLOW_PPR_OUTPUT_R1858426911545391_reset_R_1858426911545391 & p_arg_names = P2110_VENDOR1 & p_arg_names = P2110_VENDOR2 & p_arg_values = 3754 & p_arg_values = null
  
  This only happens in Internet Explorer. I use IE9, but it seems to work that way, if I put it in IE8 mode as well.
  
  I returned and tested in the Apex 4.1.1.00.23 and I got the same result.
  
  Greg

  Hi Greg,.

  Thanks again for the follow-up. You are right, it is the "Set Value" operation that causes the problem when it is called with a null value. In fact, it's a bug of IE underlaying.

  See http://stackoverflow.com/questions/5387038/null-values-shown-in-form-fields-in-ie and also http://bugs.jquery.com/ticket/5163 strengthening jQuery

  I will file a bug to use jQuery.val () workarounds to the problem.

  Thank you

• BUG status: File.deleteOnExit () does not work on open files (win32)?

  I'm a bit confused about the status of the below bug:
  
  http://bugs.Sun.com/bugdatabase/view_bug.do?bug_id=4171239
  http://bugs.Sun.com/bugdatabase/view_bug.do?bug_id=6357433
  
  Is fixed? I use jdk1.6.0_25 32-bit on a 64-bit windows computer 7 where I create a temporary folder:
  

   
  
  
      File tempDir = File.createTempFile(name, "");
      if (!(tempDir.delete())) {
        throw new IOException("Could not delete temp file" + tempDir.getAbsolutePath());
      }
      if (!(tempDir.mkdir())) {
        throw new IOException("Could not create temp file" + tempDir.getAbsolutePath());
      }
      tempDir.deleteOnExit();

  It works fine if the folder is empty. But if I put a test.txt file in the folder created its not deleted on exit. DeleteOnExit() works only on empty folders?

  Yes, what I said above.

• How to get around the java runtime bug - the indentation is overridden

  Hi all
  
  I generate xml data from a servlet and the flow of data to the client as the following code. It works fine on my local machine (the XML is well indented), but when the war file deployed to a geronimo Server 2.0.2. (It uses java 1.5.0_16). The xml streamed on without indentation
  
  

                 response.setContentType("application/xml");
                 response.setHeader("Content-disposition","attachment; filename="+fileName); 
  
                 // set up a transformer
                 TransformerFactory transfac = TransformerFactory.newInstance();
                 Transformer trans = transfac.newTransformer();
  
                 trans.setOutputProperty(OutputKeys.METHOD, "xml");                 
                 
                 trans.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); 
                 trans.setOutputProperty(OutputKeys.STANDALONE, "yes");

                 trans.transform(source, result);

  It's bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6337981 (the indentation is overridden)
  I've tried work around suggested it using OutputStreamWriter, it does not help.
  
  (I can not change anything on the server. I have to accept everything in the server)
  
  Help, please
  
  Thank you

  You must set the Indent on the factory level, see bug #6296446. This only affects 1.5; 1.6 allows you to establish the level of withdrawal on the transformer, as you did (and for the compatibility of the versions, he put on both does not hurt).

  transfac.setAttribute("indent-number", Integer.valueOf(4));

• Is it a < s:List bug?

  Flash Builder 4

  If you have a

  < s:List

  layout as TileLayout, with an itemRenderer.

  Click on a button, it filters the AC.

  Add the scroll bar because they are a more viewable objects.

  Click on the button it filters the AC.

  Removes the scroll bar because there are less than displayable objects.

  THIS IS WHERE IT GOES weird!

  Click on a button, it filters it.

  There are obviously more of viewable objects, but the scroll bars to add!

  I have a label linked to the length of the AC to tell me how much is supposed to be appear.

  He spent at least a day messing around with it.

  Looks like a bug to me.  Here's a slightly reduced test case:

  Could you please file a bug with this code to http://bugs.adobe.com and after the number of bug here?

• Please explain the meaning of 'Deferred' in the JIRA bug database

  Dear Adobe team,

  I posted a few bugs recently and discovered this morning that they are now "closed" with a "Deferred" resolution

  Some of these bugs are

  https://bugs.Adobe.com/jira/browse/FB-26396

  https://bugs.Adobe.com/jira/browse/FB-26317

  https://bugs.Adobe.com/jira/browse/FB-26081

  Please explain how to understand this decision.

  My hypothesis is that the bugs remain open until they are solved in the next version.

  Why are these bugs closed or delayed?

  When the deferred bugs are reopened?

  Management will likely chime in here.

  Briefly, the bugs get carried over to the current version. They have reviewed again when planning continues for the next version.

  The only time wherever a bug/request is really dead is when it is marked as "retirement".

• possible bug? formatting number 0 is displayed as 4 294 967 295

  This is really two questions in one. First of all, I have a routine that sometimes gives a result of 0, which is * sometimes * displayed in an AdvancedDataGrid column in the form of 4 294 967 295, which I assume is somehow a significant number (more big int?). In any case, I have one ADG with a column defined as:
  
  < mx:AdvancedDataGridColumn headerText = "Remaining work" labelFunction = "rem_work_fmt" textAlign = "right" / >
  
  The called labelFunction is illustrated below:
  
  private void rem_work_fmt(item:Object,_column:AdvancedDataGridColumn):String
  {
  var num:String = numberFormatter.format (item.get_remaining_work ());
  trace ("result:" + num);
  return num;
  }
  Track of exit impressions: "result: 0" as expected, but the number displayed in the grid is sometimes 0 and 4294967295 sometimes.
  
  More strangeness, this only happens to the last column in the ADG. I call the same logic of format on another column and have never seen a wrong result. In addition, the same 'get_remaining_work()' function is called on the same data and the result is properly displayed in a field of text as 0.
  
  Second question, I met a few other possible bugs, I didn't report because I found a work around. How to do that in the beta program?

  LW1001,

  Bugs can be filed in the public bug at http://bugs.adobe.com/flex/
  You will need to register before you can submit bugs.
  Also, if you can attach files to bug to the bug report, it makes it much easier for Adobe to investigate.

  Let me know if you have any other questions/problems.

• HScrollBar maxScrollPosition bug?

  I have a HScrollBar that sets the position of a cover-flow component.
  
  Everything works fine (the coverflow to scroll bar position adjustment and vice versa).
  
  Scroll bar sets the fine position when you click a position on the scroll bar, use the arrows, but NOT when you drag.
  
  It seems that I can't set the maxScrollPosition dynamically. If I leave it empty the scroll bar is disabled. If I give a default, I can only drag the thumb to this value.
  
  I tested I'll put everything ok as follows:
  
  SpreadScrollbar.maxScrollPosition = issuesSpreads.length;
  trace ("work" + SpreadScrollbar.maxScrollPosition.toString ());
  
  Track prints a correct value (say; 19)
  
  If I set the max position value in the MXML to {issuesSpreads.length} the scroll bar is grayed out new :(
  
  Help, please
  
  Thank you

  I found this bug from the Flex SDK bug tracking system:
  https://bugs.Adobe.com/jira/browse/SDK-11994?page=com.atlassian.JIRA.plugin.System.issueta bpanels:all - tabpanel

  She says that to fix the bug, you can call this function in your scroll bar:
  invalidateDisplayList();

  So it would look like this:
  yourScrollBarId.invalidateDisplayList ();

• HTTP Timeout - Explorer vs Firefox

  I discovered that if you make a request, using URLLoader or other type of request objects, if the connection fails to connect browsers react differently. The issue I encountered is with Firefox, it does not appear any time. If she fails to connect you will never get an onFault, or response onComplete.
  
  Has anyone else seen elsewhere? Is my best option to create my own Timer with a time-out?
  
  To reproduce: you can use the code example provided on:
  http://livedocs.Adobe.com/Flex/2/langref/Flash/NET/URLRequest.html#includeExamplesSummary
  
  Change URLRequest ("XMLFile.xml") to URLRequest ("' http://www.google.com" "), disable your network connection, run your Flex application with Firefox and explore and see the difference.
  
  Thank you

  In my view, using a timer is the best solution. Please this file as a bug in our new public bugbase for Flex at http://bugs.adobe.com/flex and mention that it's really a problem of browser/player. The team of the player is not currently a public bugbase.

• Bug Builder - .svn folders are copied to the Flex output folder

  Hello
  
  I use the control system version of Subersion (using Tortoise SVN client) to control my Flex project code.
  
  I added to the subversion repository my Flex (all files except the bin folder) project. When the Flex compiler generates the project, it copies the "html-template" file in the bin directory, it also copies the '.svn' folders that subversion system puts in the folder "html-template". This also happens if I choose to "copy the files not included in the output directory" option in the properties of the project Flex compiler. The compiler copies all ".svn" folders found in the source folder (recursively).
  
  As I see it, it's a bug because the '.svn' folders are hidden, for this purpose they may not be copied.
  Maybe it's a missing feature in the properties of the flex compiler, which tells the compiler Flex does not copy hidden files in the output directory.

  Note, that I recently logged in as https://bugs.adobe.com/jira/browse/FB-10813

  It has been marked fixed for Flex Builder 3 Beta 3 - so stay tuned and try
  It is when a new draft is available.

• BlendMode.LAYER &amp; amp; wmode = transparent &amp; amp; FF bug

  Hello, I have problems with the latest version of flash player 10. Everything worked before the upgrade, but since I'm not able to get BlendMode.LAYER and wmode = transparent works in firefox (2 or 3).
  
  I described my problem and I have files of examples here:
