  • Java parsing UTF8

    - by Jack
    I have the following issue with a UTF8 files structured as following: FIELD1§FIELD2§FIELD3§FIELD4 Looking at hexadecimal values of the file it uses A7 to codify §. So according to this codify it should be UTF8, but it's strange because A7 7F so 1 byte shouldn't be enough to codify §. So I tried using directly a BufferedReader with a specified charset: BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(input), utf8)) but when I try to tokenize the string with SmartTokenizer st = new SmartTokenizer(toTokenize, "§") (the SmartTokenizer is a modified version of the StringTokenizer that keeps empty tokens) no splitting occurs, and if I try to print the string I obtain FIELD1?FIELD2?FIELD3?... so § used in the file is different from the one specified as a the delimiter, and it's not able to print out it too. So what's the problem here? Maybe the original file should use 2 bytes to store §?

  • Why Java SimpleDateFormat().parse() is printing weird formate?

    - by MAK
    My input is String formated as the following: 3/4/2010 10:40:01 AM 3/4/2010 10:38:31 AM My code is: DateFormat dateFormat = new SimpleDateFormat("dd/mm/yyyy hh:mm:ss aa"); try { Date today = dateFormat.parse(time); System.out.println("Date Time : " + today); } catch (ParseException e) { e.printStackTrace(); } the output is: Sun Jan 03 10:38:31 AST 2010 Sun Jan 03 10:40:01 AST 2010 I'm not sure from where the day (Sun) came from? or (AST)? and why the date is wrong? I just wanted to keep the same format of the original String date and make it into a Date object. I'm using Netbeans 6.8 Mac version.

  • How do I map a java Map including another Map, as element, into hibernate *.hbm.xml

    - by Václav
    is there possibility to map something like: private Map<Website, Map<String, String>> parameterMaps = new HashMap<Website, Map<String, String>>(); Where 'Website' is my class having some strings attributes, and inner map should be some website specific url parts. I'd like to map it into *.hbm.xml rather than using annotations, because its habit in my project. I appreciate any useful reference to any manual too. Thanks!

  • long polling netty nio framework java

    - by Alfred
    Hi, How can I do long-polling using netty framework? Say for example I fetch http://localhost/waitforx but waitforx is asynchronous because it has to wait for an event? Say for example it fetches something from a blocking queue(can only fetch when data in queue). When getting item from queue I would like to sent data back to client. Hopefully somebody can give me some tips how to do this. Many thanks

  • audio processing using java

    - by Sukhhhh
    We have a requirement where we need to convert from .wav file to .mp3 and we are currently using "Tritonus" library to do that . The concern with that library is that requires "installation" of some "dll" files to the class path. I am wondering are there any API's those allow better processing without local installation. And other question is ,having mp3 format files will make it easier to join the files into a single file than having .wav files ?

  • Red5 Unable to Start Distribution.

    - by Iscariot
    I have installed subclipse, Ant, IvyDE, Red5 Plugin for eclipse, All of the Environmental variables are set and the necessary elements have been added to the path. I am attempting to create a Red5 Distribution by using eclipse, opening Build.xml right clicking dist [default] in the outline window and running as and selecting Ant Builder. Eclipse says that the build is Successful. I first stop the Red5 Service, and then I attempt to run the build I create in eclipse it fails, below are the errors that display in the command prompt. I was hoping someone else might have run into a similar issue before.

  • Java - Save video stream from Socket to File

    - by Alex
    I use my Android application for streaming video from phone camera to my PC Server and need to save them into file on HDD. So, file created and stream successfully saved, but the resulting file can not play with any video player (GOM, KMP, Windows Media Player, VLC etc.) - no picture, no sound, only playback errors. I tested my Android application into phone and may say that in this instance captured video successfully stored on phone SD card and after transfer it to PC played witout errors, so, my code is correct. In the end, I realized that the problem in the video container: data streamed from phone in MP4 format and stored in *.mp4 files on PC, and in this case, file may be incorrect for playback with video players. Can anyone suggest how to correctly save streaming video to a file? There is my code that process and store stream data (without errors handling to simplify): // getOutputMediaFile() returns a new File object DataInputStream in = new DataInputStream (server.getInputStream()); FileOutputStream videoFile = new FileOutputStream(getOutputMediaFile()); int len; byte buffer[] = new byte[8192]; while((len = in.read(buffer)) != -1) { videoFile.write(buffer, 0, len); } videoFile.close(); server.close(); Also, I would appreciate if someone will talk about the possible "pitfalls" in dealing with the conservation of media streams. Thank you, I hope for your help! Alex.

  • XML generation with java, trying to copy the whole node

    - by Pawel Mysior
    I've got an xml document that filled with people (parent node is "students", and there are 25+ "student" nodes). Each student looks like this: <student> <name></name> <surname></surname> <grades> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> <subject name=""> <small_grades></small_grades> <final_grade></final_grade> </subject> </grades> <average></average> </student> Basically, what I want to do ('ve been asked to do) is to make a program that would get 3 students with the best average. While parsing the document and getting three best students isn't too difficult, the XML generation is a pain in the ass. Right now, what I'm doing is getting every single node from student and recreating it to a new file. Is there a way to copy the whole student node with everything that's in it? Regards, Paul

  • Red5 OflaDemo Missing Java App

    - by Makram Saleh
    Hi All. I'm trying to run an application on Red5 server. It has the same basic functionality as the bundled demo named OFLADemo. So I installed Red5 and was able to see the welcome screen. I installed an app and tried the demo flash and all went well... But when I tried to install that particular application from /installer I got stuck with a dialog box with this message: installing oflaDemo-r3989-java6.war This may take a couple minutes, please wait. Waited for hours instead of minutes, but nothing happened. I was able to get that specific file from google code, but I don't know where to extract/place it. Any clues?

  • Create variable names using a loop in Java?

    - by SeerUK
    Hi, first time poster, long time reader so be gentle with me :) See the following code which works to generate me timestamps for the beginning and end of every month in a financial year. int year = 2010; // Financial year runs from Sept-Aug so earlyMonths are those where year = FY-1 and lateMonths are those where year = FY int[] earlyMonths = {8, 9, 10, 11}; // Sept to Dec int earlyYear = year -1; for (int i : earlyMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(earlyYear,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(earlyYear,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(earlyYear,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } int[] lateMonths = {0, 1, 2, 3, 4, 5, 6, 7}; // Jan to Aug for (int i : lateMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(year,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(year,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(year,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } So far so good, but in order to use these results I need these timestamps to be output to variables named by month (to be used in a prepared statement later in the code. e.g. SeptStart = sometimestamp, SeptEnd = some timestamp etc etc. I don't know if it is possible to declare new variables based on the results of each loop. Any ideas?

  • To have an Integer pointing to 3 ordered lists in Java

    - by Masi
    Which datastructure would you use in the place of X to have efficient merges, sorts and additions as described below? #1 Possible solution: one HashMap to X -datastructure Having a HashMap pointing from fileID to some datastructure linking word, wordCount and wordID may be a good solution. However, I have not found a way to implement it. I am not allowed to use Postgres or any similar tool to keep my data neutralized. I want to have efficient merges, sorts and additions according to fileID, wordID or wordCount for the type below. I have the type Words which has th field fileID that points to a list of words and to relating pieces of information: The Type class Words =================================== fileID: int [list of words] : ArrayList [list of wordCounts] : ArrayList [list of wordIDs] : ArrayList Example of the data in fileID word wordCount wordID instance1 of words 1 He 123 1111 1 llo 321 2 instance2 of words 2 Van 213 666 2 cou 777 932 Example of needed merge fileID wordID fileID wordID 1 2 1 3 wordID=2 2 2 ========> 1 2 2 3 2 2 I cannot see any usage of set-operations such as intersections here because order is needed. Having about three HashMaps makes sorting difficult: from word to wordID in a given fileID from wordID to fileID from wordID to wordCount in a given fileID

  • JAVA BubbleSort Output Plotting

    - by John Smith
    I'm not sure how to plot the output I get with my run time results for BubbleSort. Here's the thing: I've written a working BubbleSort algorithm that does exactly as it should. But I wish to plot the output, to show the following: Best Case, Worst Case, Average Case ... How would I go about plotting it on a graph? Here is the code: public class BubbleSort { static double bestTime = 10000000, worstTime = 0; public static void main(String[] args) { int BubArray[] = new int[]{13981, 6793, 2662, 10986, 733, ... #1000 integers}; System.out.println("Unsorted List Before Bubble Sort"); for(int a = 0; a < BubArray.length; a++){ System.out.print(BubArray[a] + " "); } System.out.println("\n Bubble Sort Execution ..."); for(int i=0; i<10000;i++) { bubbleSortTimeTaken(BubArray, i); } int itrs = bubbleSort(BubArray); System.out.println(""); System.out.println("Array After Bubble Sort"); System.out.println("Moves Taken for Sort : " + itrs + " Moves."); System.out.println("BestTime: " + bestTime + " WorstTime: " + worstTime); System.out.print("Sorted Array: \n"); for(int a = 0; a < BubArray.length; a++){ System.out.print(BubArray[a] + " "); } } private static int bubbleSort(int[] BubArray) { int z = BubArray.length; int temp = 0; int itrs = 0; for(int a = 0; a < z; a++){ for(int x=1; x < (z-a); x++){ if(BubArray[x-1] > BubArray[x]){ temp = BubArray[x-1]; BubArray[x-1] = BubArray[x]; BubArray[x] = temp; } itrs++; } } return itrs; } public static void bubbleSortTimeTaken(int[] BubArray, int n) { long startTime = System.nanoTime(); bubbleSort(BubArray); double timeTaken = (System.nanoTime() - startTime)/1000000d; if (timeTaken > 0) { worstTime = timeTaken; } else if (timeTaken < bestTime) { bestTime = timeTaken; } System.out.println(n + "," + timeTaken); } } The output are as the following ( execution number, time (nano/10^6): Unsorted List Before Bubble Sort 13981 6793 2662 .... #1000 integers Bubble Sort Execution ... 0, 18.319891 1, 4.728978 2, 3.670697 3, 3.648922 4, 4.161576 5, 3.824369 .... 9995, 4.331423 9996, 3.692473 9997, 3.709893 9998, 6.16055 9999, 4.32209 Array After Bubble Sort Moves Taken for Sort : 541320 Moves.

  • Java UTF-8 to ASCII conversion with supplements

    - by bozo
    Hi, we are accepting all sorts of national characters in UTF-8 string on the input, and we need to convert them to ASCII string on the output for some legacy use. (we don't accept Chinese and Japanese chars, only European languages) We have a small utility to get rid of all the diacritics: public static final String toBaseCharacters(final String sText) { if (sText == null || sText.length() == 0) return sText; final char[] chars = sText.toCharArray(); final int iSize = chars.length; final StringBuilder sb = new StringBuilder(iSize); for (int i = 0; i < iSize; i++) { String sLetter = new String(new char[] { chars[i] }); sLetter = Normalizer.normalize(sLetter, Normalizer.Form.NFC); try { byte[] bLetter = sLetter.getBytes("UTF-8"); sb.append((char) bLetter[0]); } catch (UnsupportedEncodingException e) { } } return sb.toString(); } The question is how to replace all the german sharp s (ß, Ð, d) and other characters that get through the above normalization method, with their supplements (in case of ß, supplement would probably be "ss" and in case od Ð supplement would be either "D" or "Dj"). Is there some simple way to do it, without million of .replaceAll() calls? So for example: Ðonardan = Djonardan, Blaß = Blass and so on. We can replace all "problematic" chars with empty space, but would like to avoid this to make the output as similar to the input as possible. Thank you for your answers, Bozo

  • Java - abstract class, equals(), and two subclasses

    - by msr
    Hello, I have an abstract class named Xpto and two subclasses that extend it named Person and Car. I have also a class named Test with main() and a method foo() that verifies if two persons or cars (or any object of a class that extends Xpto) are equals. Thus, I redefined equals() in both Person and Car classes. Two persons are equal when they have the same name and two cars are equal when they have the same registration. However, when I call foo() in the Test class I always get "false". I understand why: the equals() is not redefined in Xpto abstract class. So... how can I compare two persons or cars (or any object of a class that extends Xpto) in that foo() method? In summary, this is the code I have: public abstract class Xpto { } public class Person extends Xpto{ protected String name; public Person(String name){ this.name = name; } public boolean equals(Person p){ System.out.println("Person equals()?"); return this.name.compareTo(p.name) == 0 ? true : false; } } public class Car extends Xpto{ protected String registration; public Car(String registration){ this.registration = registration; } public boolean equals(Car car){ System.out.println("Car equals()?"); return this.registration.compareTo(car.registration) == 0 ? true : false; } } public class Teste { public static void foo(Xpto xpto1, Xpto xpto2){ if(xpto1.equals(xpto2)) System.out.println("xpto1.equals(xpto2) -> true"); else System.out.println("xpto1.equals(xpto2) -> false"); } public static void main(String argv[]){ Car c1 = new Car("ABC"); Car c2 = new Car("DEF"); Person p1 = new Person("Manel"); Person p2 = new Person("Manel"); foo(p1,p2); } }

  • Java split xml file

    - by CC
    Hi all, I'm working on a piece of code to split files. I want to split flat file (that's ok, it is working fine) and xml file. The idea is to split based of a number of files to split: I have a file, and I want to split it in x files (x is a parameters). I'm doing the split by taking the size of the file and spliting the size by the number of files to split. Then, mysolution was to use a BufferedReader and to use it like while ((n = reader.read(buffer, 0, buffer.length)) != -1) { { The main problem is that for the xml file I cannot just split it, but I have to split it based on a block delimited by a start xml tag and end xml tag: <start tag> bla bla xml stuff </end tag> So I cannot cut a block at the middle. So if when I'm at the half of a block, is the size of my new file is greater than my max, I will have to read until the end of the tag, and then, to start a next file. The problem is that I have all sort of cases, and is a bit difficult to search the end tag. - the block reads a text until the middle of the end tag - the block reads a text until the end of the end tag, and no more other caracter after - etc and in the same time to have a loop and read the next block. Some times the end of a block concatenated with the start of the next one, I have the end xml tag. I hope you get the idea. My question is, does anyone have some algorithm that does that more accurate and who i treating all special cases ? The idea is to split the file as quickly as possible. Thanks alot.

  • Enabling browser caching via java

    - by Franz See
    Good day, I am using CacheFilter to filter a certain path to my server (which outputs an image stream to the response stream). And I've configured it in my web.xml as follows: <filter> <filter-name>imagesCache</filter-name> <filter-class>com.samaxes.cachefilter.presentation.CacheFilter</filter-class> <init-param> <param-name>privacy</param-name> <param-value>public</param-value> </init-param> <init-param> <param-name>expirationTime</param-name> <param-value>2592000</param-value> </init-param> </filter> ... <filter-mapping> <filter-name>imagesCache</filter-name> <url-pattern>/my/path/*</url-pattern> </filter-mapping> Using my firefox, if I access my url via the address bar, it hits the server the first time but uses the cache during succeeding calls. However, if the url is inside my page ( i.e. <img src="..."/> ), it seems to hit the server all the time. [EDIT] After a few more testing, accessing my image via the address bar does not work all the time. But caching does seem to work more often with it than . As to whether it really, I am not sure. Additional Info: my path is something like /my/path?then=some&query=strings. Notice that it doesn't have an extension (i.e. gif, png, jpeg ) but it's mimetype is set properly ( image/gif, image/png, image/jpeg ). I am not sure if the lack of extension or the presence of the query strings have any impact. (Also, another note. though my url have query strings, I am using the same uri + query string over and over again with my tests). Any ideas why? Thanks

  • Blob in Java/Hibernate/sql-server 2005

    - by Ramy
    Hi, I'm trying to insert an HTML blob into our sql-server2005 database. i've been using the data-type [text] for the field the blob will eventually live in. i've also put a '@Lob' annotation on the field in the domain model. The problem comes in when the HTML blob I'm attempting to store is larger than 65536 characters. Its seems that is the caracter-limit for a text data type when using the @Lob annotation. Ideally I'd like to keep the whole blob in tact rather than chunk it up into multiple rows in the database. I appreciate any help or insight that might be provided. Thanks! _Ramy Allow me to clarify annotation: @Lob @Column(length = Integer. MAX_VALUE) //per an answer on stackoverflow private String htmlBlob; database side (sql-server-2005): CREATE TABLE dbo.IndustrySectorTearSheetBlob( ... htmlBlob text NULL ... ) Still seeing truncation after 65536 characters... EDIT: i've printed out the contents of all possible strings (only 10 right now) that would be inserted into the Database. Each string seems to contain all cahracters, judging by the fact that the close html tag is present at the end of the string....
