  • Upload image from J2ME client to a Servlet

    - by Akash
    I want to send an image from a J2ME client to a Servlet. I am able to get a byte array of the image and send it using HTTP POST. conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length); // bytes = byte array of image This is the Servlet code: String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed. Thus, either POST method or readLine() are not able to accept 0A and 0D values. Any one have any idea how to do this, or how to use any another method?

  • JTable Delete All Rows Exception

    - by Dimitri
    Hi, I'm trying to delete all entrys from my abstractTableModel. As long as I don't delete the last remaining row, everything works fine, but as soon as I delete this one, I get an ArrayOutOfBoundsException. I'm using a DefaultRowSorter and this seems to be the Exception.

  • Record/Playback with AudioQueue on iPhone

    - by Biranchi
    Hi, I am currently using Audio Queues on the iPhone to record and playback audio. What I would like to be able to do is to record some audio, allow the user to pause the record queue, and to seek back and forward through the audio to select a position from where they can start recording from again. I have got over the seeking issue by making the playback AudioQueueBuffer sizes small enough so that the play audio queue callback happens at a rate that allows the user to use a slider control to hear the audio as they adjust the slider back and forth. I think I can achieve the recording at a new position by setting the inStartingPacket parameter of the AudioFileWritePackets function that I call from the Audio Recording Queue callback. The trouble is this only inserts audio over the previously recorded audio. The file length obviously doesn't change so if the user were to go backwards and record less audio than before, the old audio still remains after the end of the newly recorded audio. Is there a way I can get the AudioFile to truncate at the point the user starts to insert the new audio, is there some other way I can remove the old audio starting at the insert position or is there a better way about going about this task? Thanks

  • Populate datagrid using Datacontext in C# WPF

    - by anon
    I'm trying to get data from file. The file first has three lines of text that describes the file, then there is a header for the data below. I've managed to extract that. What I'm having problems is getting the data below the header line. The data below the header line can look like "1 2 3 4 5 6 7 8 9 abc". DataGrid dataGrid1 = new DataGrid(); masterGrid.Children.Add(dataGrid1); using (TextReader tr = new StreamReader(@filename)) { int lineCount = 1; while (tr.Peek() >= 0) { string line = tr.ReadLine(); { string[] data = line.Trim().Split(' '); Dictionary<string, object> sensorData = new Dictionary<string, object>(); for (int i = 0, j = 0; i < data.Length; i++) { //I know that I'm delimiting the data by a space before. //but the data from the text file doesn't necessarily have //just one space between each piece of data //so if I don't do this, spaces will become part of the data. if (String.Compare(data[i]," ") > 0) { sensorData[head[j]] = data[i]; j++; } } sensorDatas.Add(sensorData); sensorData = null; } lineCount++; } } dataGrid1.DataContext = sensorDatas; I can't figure out why this doens't work. If I change "dataGrid1.DataContext = sensorDatas;" to "dataGrid1.ItemsSource = sensorDatas;" then I get the data in the proper columns, but I also get some Raw View data such as: Comparer, Count, Keys, Values as columns, which I don't want. Any insight?

  • uncompressing .zip file in linux [closed]

    - by Suren
    hi, I have a .zip file (It contains multiple files, ex: file1.txt file2.txt file3.txt.. n so on) in a directory. And my query is: How to extract the files from .zip archive to the very same directory and how to create the list of all the files extracted from .zip archive.** The extracted file name should be printed like this in the file named: file_list: file1.txt file2.txt file3.txt filen.txt I have tried the following command assuming that my .zip file name is "data.zip". unzip -qoj data.zip | unzip -ql data.zip > file_list I have used unzip -qoj data.zip to extract all the files in the same directory(quietly,overwrite,junk_path). When I try to insert -l with the first unzip command then the command doesn't extract the file in the current and only files are listed thats why I have to used unzip again after the first pipe(If I am making a mistake here let me know please). I get the following output Length Date Time Name -------- ---- ---- ---- 0 12-21-09 14:25 data/ 6148 12-21-09 14:25 data/.DS_Store 0 12-21-09 14:25 __MACOSX/ 0 12-21-09 14:25 __MACOSX/data/ 82 12-21-09 14:25 __MACOSX/data/._.DS_Store 82 12-11-09 13:59 data/file1.txt 120 12-11-09 13:59 data/file2.txt 166 12-11-09 13:59 data/file3.txt -------- ------- 6598 8 files How do I extract only file1.txt file2.txt file3.txt from this stdout? Is it possible to do this with linux command or I have to write a perl script for this? Thank you.

  • jQuery: script remember values between times it is triggered?

    - by Marius
    Hello there, I am writing an ajax script in jQuery. The script gets new or previous page from a php documents that returns HTML. If, located on page 1, I click next, the script IS able to find the next page number (page2), but when I click it AGAIN, the script again has to be able to find the next page number (page3) and at the minute it doesnt. I was wondering how I can save a variable between time a script is triggered, so that I can just + 1 to each time somebody clicks "next", and -1 when somebody clicks "previous". This is my code: $('.buttonNeste').click(function(event){ event.preventDefault(); if (page == null || id == null ) { var page = parseInt($(this).closest('.paginationFullWidth').attr('id')) + 1; var id = $(this).closest('.paginationFullWidth').siblings('.jtextfill').children('h1').attr('id'); } else { var page = page + 1; } var target = $(this); $.post( 'http://www.example.com/controllers/foo.php', { 'page': ( page ), 'id': id }, function(data) { $(target).closest('.paginationFullWidth').siblings('.commentsContainer').html(data); }); }); Thank you for your time. Kind regards, Marius

  • Bitbucket API authentication with Python's HTTPBasicAuthHandler

    - by jbochi
    I'm trying to get the list of issues on a private repository using bitbucket's API. I have confirmed that HTTP Basic authentication works with hurl, but I am unable to authenticate in Python. Adapting the code from this tutorial, I have written the following script. import cookielib import urllib2 class API(): api_url = 'http://api.bitbucket.org/1.0/' def __init__(self, username, password): self._opener = self._create_opener(username, password) def _create_opener(self, username, password): cj = cookielib.LWPCookieJar() cookie_handler = urllib2.HTTPCookieProcessor(cj) password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm() password_manager.add_password(None, self.api_url, username, password) auth_handler = urllib2.HTTPBasicAuthHandler(password_manager) opener = urllib2.build_opener(cookie_handler, auth_handler) return opener def get_issues(self, username, repository): query_url = self.api_url + 'repositories/%s/%s/issues/' % (username, repository) try: handler = self._opener.open(query_url) except urllib2.HTTPError, e: print e.headers raise e return handler.read() api = API(username='my_username', password='XXXXXXXX') api.get_issues('my_username', 'my_repository') results in: >>> Server: nginx/0.7.62 Date: Mon, 19 Apr 2010 16:15:06 GMT Content-Type: text/plain Connection: close Vary: Authorization,Cookie Content-Length: 9 Traceback (most recent call last): File "C:/USERS/personal/bitbucket-burndown/bitbucket-api.py", line 29, in <module> print api.get_issues('my_username', 'my_repository') File "C:/USERS/personal/bitbucket-burndown/bitbucket-api.py", line 25, in get_issues raise e HTTPError: HTTP Error 401: UNAUTHORIZED api.get_issues('jespern', 'bitbucket') works like a charm.

  • SqlBulkCopy causes Deadlock on SQL Server 2000.

    - by megatoast
    I have a customized data import executable in .NET 3.5 which the SqlBulkCopy to basically do faster inserts on large amounts of data. The app basically takes an input file, massages the data and bulk uploads it into a SQL Server 2000. It was written by a consultant who was building it with a SQL 2008 database environment. Would that env difference be causing this? SQL 2000 does have the bcp utility which is what BulkCopy is based on. So, When we ran this, it triggered a Deadlock error. Error details: Transaction (Process ID 58) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I've tried numerous ways to try to resolve it. like temporarily setting the connection string variable MultipleActiveResultSets=true, which wasn't ideal, but it still gives a Deadlock error. I also made sure it wasn't a connection time out problem. here's the function. Any advice? /// <summary> /// Bulks the insert. /// </summary> public void BulkInsert(string destinationTableName, DataTable dataTable) { SqlBulkCopy bulkCopy; if (this.Transaction != null) { bulkCopy = new SqlBulkCopy ( this.Connection, SqlBulkCopyOptions.TableLock, this.Transaction ); } else { bulkCopy = new SqlBulkCopy ( this.Connection.ConnectionString, SqlBulkCopyOptions.TableLock | SqlBulkCopyOptions.UseInternalTransaction ); } bulkCopy.ColumnMappings.Add("FeeScheduleID", "FeeScheduleID"); bulkCopy.ColumnMappings.Add("ProcedureID", "ProcedureID"); bulkCopy.ColumnMappings.Add("AltCode", "AltCode"); bulkCopy.ColumnMappings.Add("AltDescription", "AltDescription"); bulkCopy.ColumnMappings.Add("Fee", "Fee"); bulkCopy.ColumnMappings.Add("Discount", "Discount"); bulkCopy.ColumnMappings.Add("Comment", "Comment"); bulkCopy.ColumnMappings.Add("Description", "Description"); bulkCopy.BatchSize = dataTable.Rows.Count; bulkCopy.DestinationTableName = destinationTableName; bulkCopy.WriteToServer(dataTable); bulkCopy = null; }

  • How to use Castle Windsor with ASP.Net web forms?

    - by Xian
    I am trying to wire up dependency injection with Windsor to standard asp.net web forms. I think I have achieved this using a HttpModule and a CustomAttribute (code shown below), although the solution seems a little clunky and was wondering if there is a better supported solution out of the box with Windsor? There are several files all shown together here // index.aspx.cs public partial class IndexPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Logger.Write("page loading"); } [Inject] public ILogger Logger { get; set; } } // WindsorHttpModule.cs public class WindsorHttpModule : IHttpModule { private HttpApplication _application; private IoCProvider _iocProvider; public void Init(HttpApplication context) { _application = context; _iocProvider = context as IoCProvider; if(_iocProvider == null) { throw new InvalidOperationException("Application must implement IoCProvider"); } _application.PreRequestHandlerExecute += InitiateWindsor; } private void InitiateWindsor(object sender, System.EventArgs e) { Page currentPage = _application.Context.CurrentHandler as Page; if(currentPage != null) { InjectPropertiesOn(currentPage); currentPage.InitComplete += delegate { InjectUserControls(currentPage); }; } } private void InjectUserControls(Control parent) { if(parent.Controls != null) { foreach (Control control in parent.Controls) { if(control is UserControl) { InjectPropertiesOn(control); } InjectUserControls(control); } } } private void InjectPropertiesOn(object currentPage) { PropertyInfo[] properties = currentPage.GetType().GetProperties(); foreach(PropertyInfo property in properties) { object[] attributes = property.GetCustomAttributes(typeof (InjectAttribute), false); if(attributes != null && attributes.Length > 0) { object valueToInject = _iocProvider.Container.Resolve(property.PropertyType); property.SetValue(currentPage, valueToInject, null); } } } } // Global.asax.cs public class Global : System.Web.HttpApplication, IoCProvider { private IWindsorContainer _container; public override void Init() { base.Init(); InitializeIoC(); } private void InitializeIoC() { _container = new WindsorContainer(); _container.AddComponent<ILogger, Logger>(); } public IWindsorContainer Container { get { return _container; } } } public interface IoCProvider { IWindsorContainer Container { get; } }

  • how to handle base tag target attribute in iphone uiwebview to open new window

    - by user217428
    When the links are supposed to open a new window, iphone uiwebview won't trigger an event when user click these links. We had to use javascript to do some trick to the target attribute of the links. I can handle 'a' tag to open in the '_self' window with the trick without problem. But when I do it the same way with the 'base' tag. it doesn't work. I believe the base target is set by the javascript. But the base tag is in the head, which may be handled by the uiwebview before my javascript executed, so the target change may not reflected in the webkit engine. Could someone please give some suggestion, so I can open the link in the same uiwebview? The following is the sample HTML opened in the uiwebview <html> <head> <base target='_blank'> </head> <body> <a href='http://google.ca'>google</a> </body> </html> The following is the code to be executed in the (void) webViewDidFinishLoad: (UIWebView*)webView static NSString* js = @"" "function bkModifyBaseTargets()" "{" "var allBases = window.document.getElementsByTagName('base');" "if (allBases)" "{" "for (var i = 0; i < allBases.length; i++)" "{" "base = allBases[i];" "target = base.getAttribute('target');" "if (target)" "{" "base.setAttribute('target', '_self');" "}" "}" "}" "}"; [webView stringByEvaluatingJavaScriptFromString: js]; [webView stringByEvaluatingJavaScriptFromString: @"bkModifyBaseTargets()"];

  • Need a regular expression to parse a text body

    - by Ali
    Hi guys, I need a regular expression to parse a body of text. Basically assume this that we have text files and each of which contains random text but within the text there would be lines in the following formats - basically they are a format for denoting flight legs. eg: 13FEB2009 BDR7402 1000 UUBB 1020 UUWW FLT This line of text is always on one line The first word is a date in the format DDMMMYYYY Second word could be of any length and hold alphanumeric characters third word is the time in format HHMM - its always numeric fourth word is a location code - its almost always just alphabets but could also be alphanumeric fifth word is the arrival time in format HHMM - its always numeric sixth word is a location code - its almost always just alphabets but could also be alphanumeric Any words which follow on the same line are just definitions A text file may contain among lots of random text information one or more such lines of text. I need a way to be able to extract all this information i.e just these lines within a text file and store them with their integral parts separated as mentioned in an associative array so I have something like this: array('0'=>array('date'=>'', 'time-dept'=>'', 'flightcode'=>'',....)) I'm assuming regular expressions would be in order here. I'm using php for this - would appreciate the help guys :)

  • Singleton Roles in Moose

    - by mjn12
    I am attempting to write a singleton role using Perl and Moose. I understand a MooseX::Singleton module is available but there is always resistance when requiring another CPAN module for our project. After trying this and having a little trouble I would like to understand WHY my method is not working. The singleton role I have written is as follows: package Singleton; use Moose::Role; my $_singleInstance; around 'new' => sub { my $orig = shift; my $class = shift; if (not defined $_singleInstance ){ $_singleInstance = $class->$orig(@_); } return $_singleInstance; }; sub getInstance { return __PACKAGE__->new(); } 1; This appears to work find when only one class uses the singleton role. However when two classes (ClassA and ClassB for example) both consume the Singleton role it appears as they are both referring to a shared $_singleInstance variable. If I call ClassA-getInstance it returns a reference to a ClassA object. If I call ClassB-getInstance sometime later in the same script it returns a reference to an object of type ClassA (even though I clearly called the getInstance method for ClassB). If I dont use a role and actually copy and paste the code from the Singleton role into ClassA and ClassB it appears to work fine. Whats going on here?

  • Exception during iteration on collection and remove items from that collection

  • R: dev.copy2pdf, multiple graphic devices to a single file, how to append to file?

    - by Timtico
    Hi everybody, I have a script that makes barplots, and opens a new window when 6 barplots have been written to the screen and keeps opening new graphic devices whenever necessary. Depending on the input, this leaves me with a potential large number of openened windows (graphic devices) which I would like to write to a single PDF file. Considering my Perl background, I decided to iterate over the different graphics devices, printing them out one by one. I would like to keep appending to a single PDF file, but I do not know how to do this, or if this is even possible. I would like to avoid looping in R. :) The code I use: for (i in 1:length(dev.list()) { dev.set(which = dev.list()[i] dev.copy2pdf(device = quartz, file = "/Users/Tim/Desktop/R/Filename.pdf") } However, this is not working as it will overwrite the file each time. Now is there an append function in R, like there is in Perl. Which allows me to keep adding pages to the existing pdf file? Or is there a way to contain the information in a graphic window to a object, and keep adding new graphic devices to this object and finally print the whole thing to a file? Other possible solutions I thought about: writing different pdf files, combining them after creation (perhaps even possible in R, with the right libraries installed?) copying the information in all different windows to one big graphic device and then print this to a pdf file.

  • Equivalent of Flex DataBinding using Pure Actionscript

    - by Joshua
    What is the ActionScript equivalent of this? <mx:Label text="Hello {MyVar} World!"/> In ActionScript it would need it to look something like this: var StringToBind="Hello {MyVar} World!"; // I've Written It This Way Because I Don't Know The Exact Text To Be Bound At Design Time. [Bindable] var MyVar:String='Flex'; var Lab:Label=new Label(); Lab.text=??? ... SomeContainer.addChild(Lab); How can I accomplish this kind of "Dynamic" binding... Where I don't know the value of "StringToBind" until runtime? For the purposes of this question we can assume that I do know that any variable mentioned in "StringToBind", is guaranteed to exist at runtime. I already realize there are much more straightforward ways to accomplish this exact thing STATICALLY, and using only Flex. It's important for my project though that I understand how this could be accomplished using purely ActionScript.

  • Benchmarking a UDP server

    - by Nicolas
    I am refactoring a UDP listener from Java to C. It needs to handle between 1000 and 10000 UDP messages per second, with an average data length of around 60 bytes. There is no reply necessary. Data cannot be lost (Don't ask why UDP was decided). I fork off a process to deal with the incoming data so that I can recvfrom as quickly as possible - without filling up my kernel buffers. The child then handles the data received. In short, my algo is: Listen for data. When data is received, check for errors. Fork off a child. If I'm a child, do what I with the data and exit. If I'm a parent, reap any zombie children waitpid(-1, NULL, WNOHANG). Repeat. Firstly, any comments about the above? I'm creating the socket with socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP), binding with AF_INET and INADDR_ANY and recvfrom with no flags. Secondly, can anyone suggest something that I can use to test that this application (or at least the listener) can handle more messages than what I am expecting? Or, would I need to hack something together to do this. I'd guess the latter would be better, so that I can compare data that is generated versus data that is received. But, comments would be appreciated.

  • Using StringBuilder to process csv files to save heap space

    - by portoalet
    I am reading a csv file that has about has about 50,000 lines and 1.1MiB in size (and can grow larger). In Code1, I use String to process the csv, while in Code2 I use StringBuilder (only one thread executes the code, so no concurrency issues) Using StringBuilder makes the code a little bit harder to read that using normal String class. Am I prematurely optimizing things with StringBuilder in Code2 to save a bit of heap space and memory? Code1 fr = new FileReader(file); BufferedReader reader = new BufferedReader(fr); String line = reader.readLine(); while ( line != null ) { int separator = line.indexOf(','); String symbol = line.substring(0, seperator); int begin = separator; separator = line.indexOf(',', begin+1); String price = line.substring(begin+1, seperator); // Publish this update publisher.publishQuote(symbol, price); // Read the next line of fake update data line = reader.readLine(); } Code2 fr = new FileReader(file); StringBuilder stringBuilder = new StringBuilder(reader.readLine()); while( stringBuilder.toString() != null ) { int separator = stringBuilder.toString().indexOf(','); String symbol = stringBuilder.toString().substring(0, separator); int begin = separator; separator = stringBuilder.toString().indexOf(',', begin+1); String price = stringBuilder.toString().substring(begin+1, separator); publisher.publishQuote(symbol, price); stringBuilder.replace(0, stringBuilder.length(), reader.readLine()); }

  • Javascript Detect Control Key Held on Mouseup

    - by Michael Mikowski
    I've searched a good deal, and can't seem to find a satisfactory solution. I hope someone can help. While I am using jQuery, I am also writing many thousands of lines of Javascript. So a "pure" javascript solution is just fine. I'm trying to determine if the control key is physically held down on a mouseup event. That's it; there are no other preconditions. Does anyone know how to do this reliably, cross-browser? I've tried storing this in a state variable by noting when the key is pressed and released: // BEGIN store control key status in hash_state $().bind('keydown','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = true; console.debug( hash_state.sw_ctrldn ); }); $().bind('keyup','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = false; console.debug( hash_state.sw_ctrldn ); }); // END store control key status in hash_state However, this really doesn't work. If you test this using firebug and watch the console, you will see that auto-repeat seems to happen, and the value toggles. I inspected the mouseup event to see if there is anything useful there, but to no avail: var debugEvent = function( arg_obj_e ){ var str = ''; for ( var attr in arg_obj_e ){ str += attr + ': ' + arg_obj_e[attr] + '\n'; } console.debug(str); } Any help would be appreciated.

  • 'memcache-client' problem - app can't load the gem

    - by Max Williams
    Hi all - i'm trying to get memcached and the Interlock plugin working with a new rails app. The weird thing is that they both work fine in another app on the same machine and i can't figure out the difference that's stopping this app. The new app is rails 2.3.4 and the old one is 2.2.2 in case that's a factor. When the app starts, i get a warning from interlock: `install_memcached':Interlock::ConfigurationError: 'memcache-client' client requested but not installed. Try 'sudo gem install memcache-client'. Now, i have memcache-client installed: $> gem list | grep memcache memcache-client (1.7.8) The gem is in /var/lib/gems/1.8, which is in my GEM_PATH variable. On a bit of further investigation, the above error is raised by interlock when it refers to the MemCache class, which doesn't exist and so raises an 'anonymous module' error. So, ultimately, the problem is that MemCache isn't loaded. I have a memcached.yml in my config folder (below) however. I'm stuck - any advice anyone? #contents of config/memcached.yml defaults: namespace: millionaire #sessions: true sessions: false client: memcache-client with_finders: true development: servers: - 127.0.0.1:11211 production: servers: - 127.0.0.1:11211

  • Binary Search Tree in Java

    - by John R
    I want to make a generic BST, that can be made up of any data type, but i'm not sure how I could add things to the tree, if my BST is generic. All of my needed code is below. I want my BST made up of Locations, and sorted by the x variable. Any help is appreciated. Major thanks for looking. public void add(E element) { if (root == null) root = element; if (element < root) add(element, root.leftChild); if (element > root) add(element, root.rightChild); else System.out.println("Element Already Exists"); } private void add(E element, E currLoc) { if (currLoc == null) currLoc = element; if (element < root) add(element, currLoc.leftChild); if (element > root) add(element, currLoc.rightChild); else System.out.println("Element Already Exists); } Other Code public class BinaryNode<E> { E BinaryNode; BinaryNode nextBinaryNode; BinaryNode prevBinaryNode; public BinaryNode() { BinaryNode = null; nextBinaryNode = null; prevBinaryNode = null; } } public class Location<AnyType> extends BinaryNode { String name; int x,y; public Location() { name = null; x = 0; y = 0; } public Location(String newName, int xCord, int yCord) { name = newName; x = xCord; y = yCord; } public int equals(Location otherScene) { return name.compareToIgnoreCase(otherScene.name); } }

  • Opencv application crashes at runtime with error code 0x0000142

    - by Tuan Anh
    I have openCV and minGW installed with codeblock IDE following the instructions found here http://kevinhughes.ca/tutorials/opencv-install-on-windows-with-codeblocks-and-mingw/ i tried the simple image loading program in the article and the build process went fine. but when i tried running the output program, it crashes with the error message "the application was unable to start correctly (0xc0000142). Click OK to close the application." I used Dependency Walker to see if the program failed to load dll module and here's the output screen of Dependency Walker https://www.dropbox.com/s/f9iaftdt8atjwpl/Screenshot%202013-11-05%2022.21.45.png i am not used to DW but as i can see in its output screen, some openCV dll failed to load and the loaded Windows DLL were 64 bit instead of 32 bit (as minGW is 32 bit). I can't figure out why as i already configure the Path environment variable for the bin directory of openCV and the app still can not load the dll modules. And i think that Windows will automatically load the proper 32 bit DLLs when a 32 bit app is run but this situation the app still failed to load. Anyone has ideas?

  • Lucene stop words not removed during searching

    - by iamrohitbanga
    I have created a Lucene index with the following analyzer. public class DocSpecAnalyzer extends Analyzer { private static CharArraySet stopSet;// = new HashSet<String>(Arrays.asList());//STOP_WORDS_SET; static { stopSet = new CharArraySet(FDConstants.stopwords, true); // uncommenting this displays all the stop words // for (String s: FDConstants.stopwords) { // System.out.println(s); // } } /** * Specifies whether deprecated acronyms should be replaced with HOST type. * See {@linkplain https://issues.apache.org/jira/browse/LUCENE-1068} */ private final boolean enableStopPositionIncrements; private final Version matchVersion; public DocSpecAnalyzer(Version matchVersion) { this.matchVersion = matchVersion; enableStopPositionIncrements = StopFilter.getEnablePositionIncrementsVersionDefault(matchVersion); } public TokenStream tokenStream(String fieldName, Reader reader) { StandardTokenizer tokenStream = new StandardTokenizer(matchVersion, reader); tokenStream.setMaxTokenLength(DEFAULT_MAX_TOKEN_LENGTH); TokenStream result = new StandardFilter(tokenStream); result = new LowerCaseFilter(result); result = new StopFilter(enableStopPositionIncrements, result, stopSet); result = new PorterStemFilter(result); return result; } /** Default maximum allowed token length */ public static final int DEFAULT_MAX_TOKEN_LENGTH = 255; } Now when I search for documents for a query containing stop words, i get hits for stop words also. As I post this problem, I found the bug. It is because of http://lucene.apache.org/java/2_9_2/api/contrib-misc/org/apache/lucene/queryParser/analyzing/AnalyzingQueryParser.html not handling stop words. Is there a substitute? Update: forgot to mention that I need to do a fuzzy search. that is why i am using an AnalyzingQueryParser.
