  • Help needed implementing a web based file management system with a file hierarchy system, help neede

    - by molleman
    Hello i am trying to create a web application that will allow users to upload files online, i am using gwt while using hibernate for database communication, i am able to upload file to a server , and store them on the server. but what i want is to associate the files with a user. i want the user to be able to create folders and store a file in sub folders. my logic was to use the composite pattern to store folders and fileLocations with a user but i am am finding it difficult to implement this so i can show the files and folders within a gwt tree. what would be the best way to implement a hierarchy of folders and information of the location of a file so it could be displayed in a gwt tree? what i did have was a User would hold a reference to a root folder and then each sub folder could hold folders or fileLocations. i used the composite pattern to implement the file hierarchy, but when i want to display a the contents of a folder i need a for loop for each list. so i could a folder within a folder within a folder that would need 3 for loops to show the contents of my folders. What is the best way to implement this file management system. so what do you guys think?

    I've downloaded the jFLAC library but I can't figure out how it works. All I want to do is open a FLAC file and play it. The code example I have results in a NullPointerException on line 75 ( http://pastebin.com/Ndvhgex3 ) Any suggestions or example code would be appreciated.

  • Authenticating with Netflix: Netflix OAuth vs. SignPost OAuth: Which is correct?

    - by Stefan Kendall
    With signpost 1.2: String authUrl = provider.retrieveRequestToken( consumer, callbackUrl ); Netflix API response: <status> <status_code> 400 </status_code> <message> oauth_consumer_key is missing </message> </status> I see how to craft the URL manually via the netflix documentation, but this seems to contradict other services which use OAuth authentication. Who's incorrect, here? Is there a way to get signpost to work with Netflix, aside from contributing to the signpost source? :P

  • How to call web service with Android

    - by BobbyShaftoe
    I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. ... Ok, that's fine but it's 2008 so I figured there should be some good library for calling standard web services. The Web Service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android based phone. Thanks.

  • GAE/JDO: How to check whether a field in a detached object was loaded

    - by tempy
    My DAO detaches and then caches certain objects, and it may retrieve them with different fetch groups. Depending on which fetch group was used to retrieve the object, certain fields of that object may be available, or not. I would like to be able to test whether a given field on that object was loaded or not, but I can't simply check whether the field is null because that results in a "JDODetachedFieldAccessException" which demands that I either not access the field or add detach the field first. I could always catch that exception, but that doesn't smell right. So, does anyone know whether its possible to check if the field was detached?

  • Fetching data (responsebody) with a HttpClient in an AsyncTask and returning the data outside the As

    - by Peter Warbo
    Basically I'm wondering how I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results. What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content). This is what my code looks like simpliefied with the most important parts (I think). public class activity extends Activity { private String responseBody; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initControls(); } public void initControls() { fieldSearch = (EditText) findViewById(R.id.EditText01); buttonSearch = (Button)findViewById(R.id.Button01); buttonSearch.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){ search(); }}); } public void grabURL(String url) { new GrabURL().execute(url); } private class GrabURL extends AsyncTask<String, Void, String> { private final HttpClient client = new DefaultHttpClient(); private String content; private boolean error = false; private ProgressDialog dialog = new ProgressDialog(activity.this); protected void onPreExecute() { dialog.setMessage("Getting your data... Please wait..."); dialog.show(); } protected String doInBackground(String... urls) { try { HttpGet httpget = new HttpGet(urls[0]); ResponseHandler<String> responseHandler = new BasicResponseHandler(); content = client.execute(httpget, responseHandler); } catch (ClientProtocolException e) { error = true; cancel(true); } catch (IOException e) { error = true; cancel(true); } return content; } protected void onPostExecute(String content) { dialog.dismiss(); if (error) { Toast toast = Toast.makeText(activity.this, getString(R.string.offline), Toast.LENGTH_LONG); toast.setGravity(Gravity.TOP, 0, 75); toast.show(); } else { activity.this.setResponseBody(content); } } } public void search() { String query = fieldSearch.getText().toString(); String url = "http://example.com/example.php?query=" + query; //this is just an example url, I have a "real" url in my application but for privacy reasons I've replaced it grabURL(url); // the method that will start the asynctask processData(responseBody); // process the responseBody and display stuff on the ui-thread with the data that I would like to get from the asyntask but doesn't obviously }

  • Launching Intent.ACTION_VIEW intent not working on saved image file

    - by Savvas Dalkitsis
    First of all let me say that this questions is slightly connected to another question by me. Actually it was created because of that. I have the following code to write a bitmap downloaded from the net to a file in the sd card: // Get image from url URL u = new URL(url); HttpGet httpRequest = new HttpGet(u.toURI()); HttpClient httpclient = new DefaultHttpClient(); HttpResponse response = (HttpResponse) httpclient.execute(httpRequest); HttpEntity entity = response.getEntity(); BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); InputStream instream = bufHttpEntity.getContent(); Bitmap bmImg = BitmapFactory.decodeStream(instream); instream.close(); // Write image to a file in sd card File posterFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Android/data/com.myapp/files/image.jpg"); posterFile.createNewFile(); BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(posterFile)); Bitmap mutable = Bitmap.createScaledBitmap(bmImg,bmImg.getWidth(),bmImg.getHeight(),true); mutable.compress(Bitmap.CompressFormat.JPEG, 100, out); out.flush(); out.close(); // Launch default viewer for the file Intent intent = new Intent(); intent.setAction(android.content.Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse(posterFile.getAbsolutePath()),"image/*"); ((Activity) getContext()).startActivity(intent); A few notes. I am creating the "mutable" bitmap after seeing someone using it and it seems to work better than without it. And i am using the parse method on the Uri class and not the fromFile because in my code i am calling these in different places and when i am creating the intent i have a string path instead of a file. Now for my problem. The file gets created. The intent launches a dialog asking me to select a viewer. I have 3 viewers installed. The Astro image viewer, the default media gallery (i have a milstone on 2.1 but on the milestone the 2.1 update did not include the 3d gallery so it's the old one) and the 3d gallery from the nexus one (i found the apk in the wild). Now when i launch the 3 viewers the following happen: Astro image viewer: The activity launches but i see nothing but a black screen. Media Gallery: i get an exception dialog shown "The application Media Gallery (process com.motorola.gallery) has stopped unexpectedly. Please try again" with a force close option. 3D gallery: Everything works as it should. When i try to simply open the file using the Astro file manager (browse to it and simply click) i get the same option dialog but this time things are different: Astro image viewer: Everything works as it should. Media Gallery: Everything works as it should. 3D gallery: The activity launches but i see nothing but a black screen. As you can see everything is a complete mess. I have no idea why this happens but it happens like this every single time. It's not a random bug. Am i missing something when i am creating the intent? Or when i am creating the image file? Any ideas?

  • Using Android SAXParser, one my my XML Elements is mysteriously breaking in half.

    - by Drennen
    And its not '&' Im using the SAXParser object do parse the actual XML. This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method. However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one. This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level" <title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title> When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine. Something about StringReader and or InputSource is somehow screwing this up. Here is my method that takes and XML string and parses is through the SAXParser. public void parseXML(String XMLstring) { try { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); xr.setContentHandler(this); // Something is happening in the StringReader or InputSource // That cuts the XML element in half at the 2001 character mark. StringReader sr = new StringReader(XMLstring); InputSource is = new InputSource(sr); xr.parse(is); } catch (IOException e) { Log.e("CMS1", e.toString()); } catch (SAXException e) { Log.e("CMS2", e.toString()); } catch (ParserConfigurationException e) { Log.e("CMS3", e.toString()); } } I would greatly appreciate any ideas on how to not have 'characters' firing off twice when I get to this point in the XML String. Or, show me how to use a POST request and still pass off the URL to the Parse function. THANK YOU.

  • Check if a String is a double or an int?

  • Spring Security: how to implement Brute Force Detection (BFD)?

    - by Kdeveloper
    My web applications security is handled by Spring Security 3.02 but I can't find any out of the box support for Brute Force Detection. I would like to implement some application level BFD protection. For example by storing failed login attempt per user in the database (JPA). The attacked user accounts could then get a lockout period or a forced account re-activation by e-mail. What's the best way to implement this with Spring Security? Does any body have example code or best practices on this?

  • Please help with my JSP Internationalization problem

    - by wokena
    I have problem with I18N in JSP, specifically, with forms. When I enter some Czech characters (e.g., "ešcržýá...") into my page one form, into the field "fieldOne", and then show text from that field on page two, instead of Czech characters I see this as "čč". (Note, the second page gets the Czech characters with "request.getProperty("fieldOne")") Here is the source code: Page one: <%@page contentType="text/html"%> <%@page pageEncoding="UTF-8"%> <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %> <html> <head></head> <body> <form action="druha.jsp" method="post"> <input type="textarea" name="fieldOne"> <input type="submit"> </form> </body> </html> Page two: <%@page contentType="text/html" pageEncoding="UTF-8"%> <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %> <html> <head></head> <body> <h1>The text: </h1> <%=request.getProperty("fieldOne")%> </body> </html> Thanks for help...

  • Fastest gap sequence for shell sort ?

    - by Tony
    According to Marcin Ciura's Optimal (best known) sequence of increments for shell sort algorithm. The best sequence for shellsort is 1, 4, 10, 23, 57, 132, 301, 701... But how can I generate such a sequence ? In Marcin Ciura's paper he said : Both Knuth’s and Hibbard’s sequences are relatively bad, because they are defined by simple linear recurrences but most algorithm books I searched , they all tend to use Knuth’s sequence : k = 3k + 1 ; because it's easy to generate , what's your way of generating shellsort sequence ?

  • Stopping background services during an android activity

    - by fanar
    I am developing an android game right now, and it requires very precise timing and synchronization. That said, it is essential that there is no lag during the game. However I sometimes get lag spikes in the game, and I know its not the GC because I have run the ddms tool, and eliminated all the GC calls. However, I do see alot of background services popping up in my ddms logcat. Is there anyway to pause all services when my game is running? I would appreciate any other solutions. Thanks

  • Casting of interfaces

    - by Srinivas Reddy Thatiparthy
    interfaces provide a useful abstraction capability. One can have a class Foo implement some interfaces, say A, B, and C. Some client code may get a reference of type A, others one of type B, etc. each actually the same Foo object but the interface exposing only a narrow subset of the functionality. Of course, evil client code can try to cast the A reference to Foo, then access the other functionality.How to prevent this?

  • Class scope variable vs method scope variable

    - by Masud
    I know that variable scope is enclosed by a start of block { and an end of block }. If the same variable is declared within the block, then the compile error Variable already defined occurs. But take a look at following example. public class Test{ int x=0;// Class scope variable public void m(){ int x=9; //redeclaration of x is valid within the scope of same x. if(true){ int x=7; // but this redeclaration generates a compile time error. } } Here, x can be redeclared in a method, although it's already declared in the class. But in the if block, x can't be redeclared. Why is it that redeclaration of a class scope variable doesn't generate an error, but a method scope variable redeclaration generates an error?

  • Getting document.xml from a docx file using ZipInputStream

    - by meenakshik
    Hello, I have a inputStream of a docx file and I need to get hold of the document.xml which lies inside the docx. I am using ZipInputStream to read my stream and my code is something like ZipInputStream docXFile = new ZipInputStream(fileName); ZipEntry zipEntry; while ((zipEntry = docXFile.getNextEntry()) != null) { if(zipEntry.getName().equals("word/document.xml")) { System.out.println(" --> zip Entry is "+zipEntry.getName()); } } As you can see The output for zipEntry.getName comes as "word/document.xml" at some point. I need to pass this document.xml as a stream and unlike the ZipFile method where you can easily pass this on calling .getInputStream, I am wondering how can I do this docXFile? Thanks in advance, Meenakshi

  • Dynamically building and updating Histograms with JFreeChart

    - by job
    I've got a stream of incoming data that I would like to plot using a simple histogram. I don't know the range of values, or the proper resolution or bin width to use for the histogram. SimpleHistogramDataset provides some of this functionality, but I don't want to have to deal with catching exceptions in order to add new bins if the new value isn't covered. In addition, it doesn't easily allow me to rebuild the histogram using a different bin width (perhaps an integer multiples of some initial set width). Is there an easy way to accomplish this with JFreeChart or some alternate charting library, or am I going to have to write my own class here?
