NullPointerException in code XML DB

Hello

I always use 2.4.16 on the beta server.
Sometimes after recovery and run a new query, I get the following exception:
java.lang.NullPointerException
     com.sleepycat.dbxml.XmlManager.createTransaction(XmlManager.java:258)
     com.sleepycat.dbxml.XmlManager.createTransaction(XmlManager.java:269)
        .... <My code>
Probably, I'm doing something wrong in terms of recovery logic, but I guess that this kind of exceptions should not be thrown from the code of the library, or at least when I invoke XmlManager.createTransaction (). Explicit exception more would help solve this problem. In fact, this is caused by the dbenv object is null. So the question is, why is it OK to create the XmlManager object that contains null environment indoors?

Thank you
Vyacheslav

Vyacheslav,

The only way that the reference of the environment within the XmlManager object can become null is if XmlManager.delete () is called, and then the object is reused. Is it possible what is happening? There is no way that you can successfully create a XmlManager object without ending up with an environment.

Kind regards
George

  • Reading XML document

    Hey programmers,.

    I opened a thread yesterday regarding recovery code XML from a server (http://supportforums.blackberry.com/t5/Java-Development/How-to-retrieve-XML-from-server-response/m-p...) and got several nice answers and so I thought that the problem had disappeared. In fact, he only changed form.

    So I have another question for you: how to recover data from a Document and display it on the screen?

    Number of points:

    -J' tried function getType() as suggested in the post mentioned, I get a text/xml response.

    -J' have tried to use the getTextContent() on the document to put it in a TextField, it might be a rookie mistake.

    -J' I tried to put my stream to a string, but then I get something like "rim.blabla.blabla@812371".

    -J' tried to simply open a dialog with the document.getTextContent () method, but a dialog box empty is displayed.

    -J' read this post (http://supportforums.blackberry.com/t5/Java-Development/cannot-read-nodes-in-xml/m-p/324562), I would do something like this to read my XML?

    Here are some relevant parts of my code (_http is my connection):

    DocumentBuilderFactory plant = DocumentBuilderFactory.newInstance ();
    DocumentBuilder builder = factory.newDocumentBuilder ();
    Doc document = builder.parse (_http.openInputStream ());
    _HTTP. Close();

    If (doc! = null) Dialog.inform ("reading the document"); Which appears still, so I guess that is not null

    I don't really know much to XML and any help would be much appreciated.

    Yet once, I give a lot of congratulations!

    I got my answer, it works when adapt you the code in XMLDemo with the solution provided by Jcarty in the post mentioned in the original post.

    In the end, it came to this:

    -Open the connection http and everything

    -retrieve data with:

    DocumentBuilderFactory plant = DocumentBuilderFactory.newInstance ();
    DocumentBuilder builder = factory.newDocumentBuilder ();
    Doc document = builder.parse (_http.openInputStream ());
    _HTTP. Close();

    -change the constructor of the XMLDemoScreen class so there Document as an argument:

    public XMLDemoScreen (Document doc) {...}

    -change the document acquired the manufacturer as:

    Document document = doc;

    But I suspect that it worked because the XML was fairly simple.

    In any case, thank you very much for your help Simon, Bravo to you as promised...

  • The location of the XML file?

    Hi - Maybe it's a weird question, but I hope someone can help me.  I'm supposed to copy and paste the XML of my client on the server whenever it is updated through DW when connected to FTP.  So far, I have not been able to access the server, so I have no way of knowing exactly where the XML file.  This is the page which takes XML:

    http://www.gulfspillrestoration.NOAA.gov/oil-spill/Gulf-spill-data/

    I assumed that there is a kind of folder on the server that holds the file called "matrix".  For the life of me, after looking at the link above, code I can't well it say anything on a matrix file.

    In DW, I made a small test page and put in place a Spry data set and took a picture of the code [see below]:

    photo1.jpg

    Spry shows clearly where the file is located in the photo above, but I can't find it on the link.  In addition, scientists are telling me that all I have to do is to download the XML through WordPress (the above site using WP CMS) but when I did it - downloaded the XML through WP - it is not too much to write the previous version but rather re - name (such as matrix1.xml).

    So I think the only way to download and replace a DW FTP access and copy and paste the new code XML on the server.

    Is my analogy this correct?  You can see the path I might be dominant in the page above that points to the matrix file?  I want to just make sure that the XML file is located on the link server in a directory above.

    Thank you.

    Sorry - I was referring to your second question on downloading the file with FTP. If you want to download it with WP, and then delete the existing since the first Panel to SUPPORT XML file.

    is your code xml in an external file?

    If so, (for example, resources.xml), you would use:

    var xml

    var urlLoader:URLLoader = new URLLoader();

    urlLoader.addEventListener (Event.COMPLETE, completeF);

    urlLoader.load (new URLRequest ("resources.xml"));

    function completeF(e:Event):void {}

    XML = e.Target.Data;

    }

    public static function getLanguage(tag:String):String{
    if(xml[tag]){
    return xml[tag];

    } else {
    return "Error";
    }

  • How can I display the value of an XML element in my dynamic textbox?

    I followed the instructions of the forum here. When I examined the record/document, the result did not 100% accurate.

    Here is my Code XML and Flash Code:

    XML

    <? XML version = "1.0" encoding = "UTF-8" standalone = "yes"? >

    < userbase >

    Test line 1 < projinfo > < / projinfo >

    < / userbase >

    Flash

    var my_xml:XML = new XML();

    var myURL:URLRequest = new URLRequest ("userbase.xml");

    var loader_URL:URLLoader = new URLLoader (myURL);

    loader_URL.addEventListener ("complete", fileLoaded);

    function fileLoaded(e:Event):void

    {

    my_xml = XML (loader_URL.data);

    mynamehosp. Text = my_xml.projinfo;

    }

    When I saw the dynamic textbox file showed "line of Test." If I did the < projinfo > element reads like this:

    < projinfo > Test line 1 more text here < / projinfo >

    The dynamic TextBox was 'Test line more text here. It is completely ignoring the number "1". How can I fix it? When our company actually uses it, it is possible that we will have (a) number (s) in the values of the organization unit.

    Any ideas?

    The code is very well. Probably you embed the police, and if you did you do have figures included.

  • #DATA # table XML

    The field #DATA # Chart XML takes data from your SQL query and it wraps in XML so that AnyChart can return the table correctly.

    Is it possible for me to customize how the XML is generated?
    Where can I find the definition of the field #DATA #?

    Thank you
    Austin

    Hi Austin,.

    First of all, what APEX version do you use? Before APEX 4.0, Flash cards are supported using AnyChart 3.3 graphics, but with APEX 4.0, we have integrated AnyChart 5 cards. The XML reference differs a lot between releases two chart, so I just want to make sure I provide you with the correct information for the version of graphics you ' using #re.

    The #DATA substitution string # on your list THAT XML is replaced at run time with XML tags containing the result set of your query for the chart series. If the XML table did not contain the #DATA substitution string #, then we assume that you provide your own data, and the chart series query will not be used. The generation of the XML tags for data differs from the type of graph type chart for example data for a pie chart labels are very different from that of a Gantt chart. Generally, users don't need to worry about this. They just need to provide the graphic series query, and the underlying logic supports the rest. However, if you need to customize only XML tags for data, for some reason, then you essentially have two options here:

    (1) hard-code XML necessary in the area of Custom XML in your chart. This would require that you set "Use Custom XML" Yes, on the page table and in the area of Custom XML attributes, replace #DATA # by your XML example

    
      
        
        
        
        
        
        
        
        
      
    
    

    NOTE: the above XML code is AnyChart 5 format, so if you use graphics AnyChart 3.3 XML code will look very different. I can provide a sample for that if needed. The reference XML 3.3 AnyChart are available here: http://3.anychart.com/products/docs/anychart/index.htm and the reference to XML AnyChart 5 are available here: http://anychart.com/products/anychart/docs/xmlReference/index.html.

    or

    (2) to generate your own data, through a process of page labels, for example, save the output in a page hidden item and then make reference to this element of the page on the list XML custom... again, you would remove the #DATA substitution string # and replaced by a reference to a hidden example item & P1_DATA. I had an example how to do that on my example of thresholds in sample, here: http://apex.oracle.com/pls/apex/f?p=36648:35. Basically, I used an application process to generate XML, to be customized because the tag must refer to a threshold attribute for example , and by default, the tag does not reference this attribute.

    I hope that the above information is useful and if you need further explanation or assistance, let me know.

  • XML with buttons as2

    OK, we have the parts in a diagram that our customers will have to click on to add to their shopping cart and other things.  the TI guys want set me up an xml file in flash. say, the user clicks on a screw, a javascript 'window' opens with more information on the screw and there will be a few buttons to add to cart and stuff like that. I guess that xml is for information, prices and stuff like that, but what I need to know is...

    What should I do to set up properly? they need to be pimples? video clips? How should I name the buttons? is the name of the file must match the name in the xml file? (I guess it is)

    I already have an xml file that is set up for it. but since this is my first use of XML, I want to make sure I put in place correctly the first time so I don't have to redo a lot.

    Sorry, I know it's a very broad question. but any help would be much appreciated. Thank you! -mitchell

    so, it's a typical application.  you will not be in place the xml file in flash.  you create (and update) of the XML outside flash.

    you install flash to load the xml file and analyze it using the xml class:

    xml.ignoreWhite = true;

    xml.onLoad = parseXML;

    XML. Load ("yourxml.xml");

  • PHP, xml and Flash

    Hello

    Someone can help me. I try to query an sql database and echo the image in xml format so I can display the image in flash.

    I already know how to query and echo the url of the image of the database.

    This is the code:

    The database is queried at this stage already.

    echo "<? XML version=\"1.01\"? " "> \n";

    echo "< content > \n";

    While ($Nile = mysql_fetch_assoc (Run))

    }

    echo "< / content > \n";

    Flash I creat table to insert a URL and an xml object echoes images. It looks like this.

    This is after you have created the table of object and xml next url the loop for to insert the XML.

    thexml.onLoad = function)

    {

    var photos: Array = thisfirstChild.childNodes;

    for (i = 0; i < photos.length; i ++)

    {

    This pushes the XML in a table of URLs

    URLs.push (photos [i]. Attributes.URL);

    }

    This is supposed to load individual data into the flash movie object.

    movieobject.loadMovie(urls[0]);

    movieobject.loadMovie(urls[1]);

    }

    x.Load (Content.php);

    The echo in the first code xml produces a url link that contains a link to an image in the database. The flash is supposed to display the image on a flash clip call movieobject animation. I have some difficulty in getting the image displayed in flash. If anyone can change or provide the new code, it would be really useful.
