• Java: Line appears when using AffineTransform to scale image

  - by Malakim

  Hi, I'm having a problem with image scaling. When I use the following code to scale an image it ends up with a line either at the bottom or on the right side of the image. double scale = 1; if (scaleHeight >= scaleWidth) { scale = scaleWidth; } else { scale = scaleHeight; } AffineTransform af = new AffineTransform(); af.scale(scale, scale); AffineTransformOp operation = new AffineTransformOp(af, AffineTransformOp.TYPE_NEAREST_NEIGHBOR); BufferedImage bufferedThumb = operation.filter(img, null); The original image is here: http://tinyurl.com/yzv6r7h The scaled image: http://tinyurl.com/yk6e8ga Does anyone know why the line appears? Thanks!

• Loopj Android Async Http - onFailure not fired

  - by Ashley Staggs

  I am using the great async http library from loopj, but I have run into a small snag. If the user has no internet connection or loses their connection, the app just won't return anything. This part is expected, but it also doesn't fire the onFailure method. Also, the code I have used when there is an internet connection does work so there is no problem on the server end. Here is some code that is stripped down to the minimum. It also doesn't work (I have tested this too) String url = getString(R.string.baseurl) + "/appconnect.php"; client.getHttpClient().getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true); client.get(url, null, new JsonHttpResponseHandler() { @Override public void onSuccess(JSONArray response) { Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show(); } @Override public void onFailure(Throwable e, JSONArray errorResponse) { Toast.makeText(getApplicationContext(), "Failure", Toast.LENGTH_SHORT).show(); } }); Thanks, Ashley

• Accessing FacesContext from Web Service

  - by scriptmonster

  I'm developing a Web Service which will be called by clients which are written by me. In the web service I need to use application-wide objects which eases the load of application on the system. I have implemented my application-wide objects as shown in this question. I can use my object in a jsf page with no problem as follows. MyObject mo = (MyObject) FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().get("MyObjectsName"); But when it comes to use it in a Web Service Request FacesContext.getCurrentInstance() returns null. Is there any way to use the FacesContext in a web service.

• How do I change the effective user of psql?

  - by gvkv

  I'm using psql to run a simple set of COPY statements contained in a file: psql -d mydb -f 'wbf_queries.data.sql' where wbf_queries.data.sql contains lines: copy <my_query> to '/home/gvkv/mydata' delimiter ',' null ''; ... but I get a permission denied error: ... ERROR: could not open file ... for writing: Permission denied I'm connecting under my user account (gvkv) which is also a superuser in PostgreSQL. Obviously, psql is running under a different (effective) user but I don't know how to change this. Can it be done within psql or do I need some unix-fu?

• New Session is created between consecutive servlet request from an Applet and a managed bean??

  - by khue

  Hi, I want to pass parameters betweeen applet and jsf components So when a value of a input textbox changed, its binding backing bean makes connection to a servlet. The servlet create an attribute and save to HttpSession using (request.getSession(true)).setAttribute(name, value); Then at some event, applet will access another servlet. This servlet will try to retrieve the Attribute saved to Session previously. However, everytime, the attirbute returned is null as the new session is created instead. My question is: Is the session should be persist? ( I checked allowcookies, session timeout for weblogic) If yes, what might go wrong with my app? Thanks a lot for your help. Regards K.

• Authentication from url in Restlet

  - by DutrowLLC

  I've been using Restlets "ChallengeResponse" mechanism to authenticate users so far. ChallengeResponse challengeResponse = getRequest().getChallengeResponse(); if( challengeResponse == null ){ throw new RuntimeException("not authenticated"); } String login = challengeResponse.getIdentifier(); String password = new String(challengeResponse.getSecret()); From my understanding, "ChallengeResponse" requires that the username and password are put into headers. However a client needs to put the credentials into the url like so: https://username:[email protected]/my_secure_document When I looked at what was actually sent, it looks like the password is being hashed. What is the proper way to authenticate in this fashion using Restlet?

• PHP Fatal error, trying to request method inside model multiple times

  - by Tom

  The error message [23-Mar-2010 08:36:16] PHP Fatal error: Cannot redeclare humanize() (previously declared in /Users/tmclssns/Sites/nadar/nadar/trunk/webapp/application/filer/models/Filer/Aggregate.php:133) in /Users/tmclssns/Sites/nadar/nadar/trunk/webapp/application/filer/models/Filer/Aggregate.php on line 133 I have a "Filer" model which contains several methods to generate graphs. Each method in there related to generating graphs has the suffix "Graph" in the method name. As we have some performance issues, I try to render the graphs in advance (using cron) instead of rendering them on each request. The code below is what I came up with: public function generategraphsAction() { $this->_helper->viewRenderer->setNoRender(); $config = Zend_Registry::get('config'); $id = $this->_getParam('filerid'); $filer = new Filer($id); $filer_methods = get_class_methods($filer); foreach ($filer_methods as $filer_method) { if (preg_match('/^(.*)Graph$/i', $filer_method, $matches)) { $path = $config->imaging_caching_dir . "/$id/{$matches[1]}.png"; $filer->$matches[0]($path); } } // var_dump(get_class_methods($filer)); die; } The result from the var_dump(), when uncommented, is: array 0 => string '__construct' (length=11) 1 => string 'find_by_name' (length=12) 2 => string 'getPartner' (length=10) 3 => string 'getSlots' (length=8) 4 => string 'getGroups' (length=9) 5 => string 'grouplist' (length=9) 6 => string 'getAggregates' (length=13) 7 => string 'getVolumes' (length=10) 8 => string 'getAggregateVolumes' (length=19) 9 => string 'getShelves' (length=10) 10 => string 'getAutoSupportHistory' (length=21) 11 => string 'getAutoSupportMail' (length=18) 12 => string 'getOrphans' (length=10) 13 => string 'getAll' (length=6) 14 => string 'getDiskRevOverview' (length=18) 15 => string 'getDiskTypeOverview' (length=19) 16 => string 'getDiskTypeSizeFunctionOverview' (length=31) 17 => string 'getLicenses' (length=11) 18 => string 'removeGroup' (length=11) 19 => string 'addGroup' (length=8) 20 => string 'hasGroup' (length=8) 21 => string 'aggdefaultGraph' (length=15) 22 => string 'aggbarGraph' (length=11) 23 => string 'voldefaultGraph' (length=15) 24 => string 'volbarGraph' (length=11) 25 => string 'replicationGraph' (length=16) 26 => string 'getReplicationData' (length=18) 27 => string 'humanize' (length=8) 28 => string 'getFiler' (length=8) 29 => string 'getOptions' (length=10) 30 => string 'getCifsInfo' (length=11) 31 => string 'getCifsStats' (length=12) 32 => string '__get' (length=5) 33 => string 'tr' (length=2) 34 => string 'trs' (length=3) 35 => string 'fieldList' (length=9) The generategraphsAction() method finds the 'Graph' methods correctly: array 0 => string 'aggdefaultGraph' (length=15) 1 => string 'aggdefault' (length=10) array 0 => string 'aggbarGraph' (length=11) 1 => string 'aggbar' (length=6) array 0 => string 'voldefaultGraph' (length=15) 1 => string 'voldefault' (length=10) array 0 => string 'volbarGraph' (length=11) 1 => string 'volbar' (length=6) array 0 => string 'replicationGraph' (length=16) 1 => string 'replication' (length=11) However when the first graph is generated, it generates the above listed PHP fatal error. Anyone can come up with a solution to this? I tried to pass by reference or switch a few things around (like re declare the Filer model, $current_filer = new Filer($id); and unset() it again after the request, but resulted in the same error) without much success. The referenced method "humanize" isn't used for anything I'm doing at the moment, but belongs to the Model because it's used in several other places. Of course, removing the method is not really an option right now, and the model contains several other methods as well so I assume if I just move the humanize method around, it will generate an error on the next one. For reference, the humanize() method: public function humanize ($kbytes, $unit = null) { // KiloByte, Megabyte, GigaByte, TeraByte, PetaByte, ExaByte, ZettaByte, YottaByte $units = array('KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'); if (null !== $units) { $i = array_search(substr($unit, -2), $units); if (! $i) { $i = floor((strlen($kbytes) - 1) / 3); } } else { $i = floor((strlen($kbytes) - 1) / 3); } $newSize = round($kbytes / pow(1024, $i), 2); return $newSize . $units[$i]; } Thanks in advance for the help offered.

• Rails: Generated tokens missing occasionally

  - by Vincent Chan

  We generate an unique token for each user and store it on database. Everything is working fine in the local environment. However, after we upload the codes to the production server on Engine Yard, things become weird. We tried to register an account right after the deploy. It is working fine and we can see the token in the db. But after that, when we register new accounts, we cannot see any tokens. We only have NULL in the db. Not sure what caused this problem because we can't re-produce this in the local machine. Thanks for your help.

• Using @NotNull in a project where both IntelliJ and Eclipse developers are working

  - by Gugussee

  A co-worker on IntelliJ IDEA (working on another project) showed me the amazing @NotNull annotation. I've read messages here on SO about how starting to add @NotNull everywhere saved lots of time and headaches (and IntelliJ 10 can even add automatically @NotNull to old code when it detects that null would break havoc). Since I read my first "Probable @NotNull violation" message (in real-time, in the IDE, even on a partial .java file that doesn't compile yet) my jaw dropped and I got hooked. So I was wondering: is there anything that needs to be known if we want to start using @NotNull in a project where developers are using both Eclipse and IntelliJ? I know IntelliJ ships with the annotations.jar. Is this compatible with Eclipse?

• Subquery works in 9i but not in 11g

  - by Zsuetam

  Statement below is working on Oracle 9i but not on Oracle 11g SELECT * FROM ( SELECT 0 scrnfail_rate, '9' zz, 7 hh FROM DUAL UNION ALL SELECT 0 scrnfail_rate, '9' zz, 7 hh FROM DUAL ) WHERE zz IS NOT NULL AND TO_CHAR (hh) NOT IN ( SELECT DECODE ( scrnfail_rate, 0, -1, ROUND (LEVEL * 1 / (scrnfail_rate / 100)) - ROUND (1 / (2 * (scrnfail_rate / 100))) ) AS nno FROM DUAL WHERE NVL (scrnfail_rate, 0) > 0 CONNECT BY LEVEL <= ROUND(9 * scrnfail_rate / 100) ) It looks like Oracle 11g is ignoring where decode or even where clause in the subquery. This query should return two rows as it does on Oracle 9i, but results ORA-01476: divisor is equal to zero on Oracle 11g EE 11.2.0.1.0 - 64bit. Can anyone help? Thanks!

• Authorization in a more purely OOP style...

  - by noblethrasher

  I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

• Write a file in UTF-8 using FileWriter (Java)?

  I have the following code however, I want it to write as a UTF-8 file to handle foreign characters. Is there a way of doing this, is there some need to have a parameter? I would really appreciate your help with this. Thanks. try { BufferedReader reader = new BufferedReader(new FileReader("C:/Users/Jess/My Documents/actresses.list")); writer = new BufferedWriter(new FileWriter("C:/Users/Jess/My Documents/actressesFormatted.csv")); while( (line = reader.readLine()) != null) { //If the line starts with a tab then we just want to add a movie //using the current actor's name. if(line.length() == 0) continue; else if(line.charAt(0) == '\t') { readMovieLine2(0, line, surname.toString(), forename.toString()); } //Else we've reached a new actor else { readActorName(line); } } } catch (IOException e) { e.printStackTrace(); } }

• How do you print a limited number of characters?

  - by Mike Pateras

  Sorry to put a post up about something so simple, but I don't see what I'm doing wrong here. char data[1024]; DWORD numRead; ReadFile(handle, data, 1024, &numRead, NULL); if (numRead > 0) printf(data, "%.5s"); My intention with the above is to read data from a file, and then only print out 5 characters. However, it prints out all 1024 characters, which is contrary to what I'm reading here. The goal, of course, is to do something like: printf(data, "%.*s", numRead); What am I doing wrong here?

• Insert query results into table in ms access 2010

  - by CodeMed

  I need to transform data from one schema into another in an MS Access database. This involves writing queries to select data from the old schema and then inserting the results of the queries into tables in the new schema. The below is an example of what I am trying to do. The SELECT component of the below works fine, but the INSERT component does not work. Can someone show me how to fix the below so that it effectively inserts the results of the SELECT statement into the destination table? INSERT INTO CompaniesTable (CompanyName) VALUES ( SELECT DISTINCT IIF(a.FIRM_NAME IS NULL, b.SUBACCOUNT_COMPANY_NAME, a.FIRM_NAME) AS CompanyName FROM (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS a LEFT JOIN (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS b ON a.ContactID = b.ContactID ); The definition of the target table (CompaniesTable) is: CompanyID Autonumber CompanyName Text Description Text WebSite Text Email Text TypeNumber Number

• JQuery .submit() changes post data

  - by ajbeaven

  I'm posting a form with javascript and it seems to be changing a value that I've entered in. Html: <% using (Html.BeginForm("ChangeTime", "Cart", new { cartItemId = cartItem.CartItemID }, FormMethod.Post, null)) { %> <%= Html.TextBox("startTime")%> <input type="submit" value="Update" /> <% } %> JQuery: <script type="text/javascript"> $('#startTime').change(function() { $(this).parent('form').submit(); }); </script> When I put a time in the textbox (05/05/2010 06:08 am), the form is submitted, however the string as it comes through, is 05/05/2010 - with the time part removed. I see this in fiddler. If get rid of the javascript and click the button above, it goes through how it should. Why is JQuery changing my text?

• DialogBox in Win32 - Prevent multiple instance

  - by UK

  Hello all, I have a program which creates DialogBox window when user clicks the menu item from tray icon, case ID_OPTIONS: DialogBox ( GetModuleHandle ( NULL ), MAKEINTRESOURCE ( IDD_SETUP_DIALOG ), hWnd, reinterpret_cast<DLGPROC>(SetupDlgProc) ); return 0; But the problem here is everytime when users clicks item from tray , a new instance of the dialogbox appears. Is there anyway to prevent this multiple instance ? BTW, my SetupDlgProc looks like this, BOOL CALLBACK SetupDlgProc ( HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam ) { switch ( Message ) { case WM_INITDIALOG: ... } } Thanks for your help.

• Rotate a feature Image in Open Layers

  - by Ozaki

  I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

• is my function correct?

  - by sbsp

  This is part of an assignment so please dont post solutions, just point me in the right direction if possible? I am passing a pointer to a char array to my method, as well as a value for the actual height of the char array. I am looping through to see if all values are 0, if they are then return 0, esle return one The method is used as a test to see if i should free memory or not and set the pointer to null if it is full of 0's. The issue i am having is that the programme should have "some unfree" memory at the end, so i have no idea whether or not its doing it correctly - and gdb i struggle with immensley. Thanks for reading int shouldBeNull(char *charPointer, int sizeOfCharArray) { int isIn = 0; int i = 0; while(i < sizeOfCharArray){ if(*charPointer != '0'){ isIn = 1; break; } i++; charPointer++; } return isIn; }
