Java barcode scanner help

Hi. I am working on a barcode scanning program in Java.
I have a Wasp WCS3905 USB barcode scanner and what I want to do is scan the barcode of anything (chocolates, books, etc) and then I want the program to open the file where the barcodes and respective names of products are stored and display the scanned barcode and the name of the product.
(ie: 5000158064041 --- Headache Tablets)
That is how I want to display it. Nothing fancy, just a single line with the barcode and the name of product.
This is what I have done so far:
# I have an applet with a textfield and a button. The textfield received focus each time the applet starts and when I scan the barcode it appears in the textfield. The button is used to clear the text in the textfield.
I haven't created the products file yet(with barcodes and names) because I don't know how I need to sctructure it. Does it need to be an Access file or can it be a Notepad file?
And also, could the program fetch the product name as soon as the barcode appears in the textfield or do I need to click a button which will fetch the name?
Thanks in advance and any help will be appreciated.

And also I am not sure what you mean by "hardcode a Map containing a few barcodes". Could you elaborate on that one for me please?Instead of fetching the name from a database or file you retrieve it from a Map which you have manually filled in your code:
Map m = new HashMap<String, String>();
m.put("5000158064041", "Headache Tablets");
m.put("5000158064055", "Beer");
m.put("5000158064123", "Condoms");
System.out.println(m.get("5000158064055"));>
Thank you.

  • Barcode scanner help

    Hello friends
    I have a big problem using my old metrologic ms9520 barcode scanner.My graduation project depends on barcode scanner and I use that scanner.I read in one forum that it works like a keyboard to get barcode data from it,but I tried that,no results.Also I read that I can do tat by downloading javacomm 2.0 which contains a dll file and properties file but when I downloaded javacomm 3.0 but I didnt found that files just a jar file javacomm.jar.
    I dont know how to retrieve barcode information using that scanner.
    I cant download its configuration files on the site " http://www.honeywellaidc.com/Site.aspx/eu/fr/resources/product_downloads/software/?product=297 ".
    Please friends help me because time is against me
    Thank you very much

  • Wrong characters in KeyEvents generated from input of barcode scanner

    Hi everybody, :-)
    I have a problem with KeyEvents coming from a barcode scanner. The issue seems to have creeped in somewhere between JSE 6u3 and 6u10, as in the former it works as expected and in the latter it does not. The problem persists still, we also tested it with 6u22 and 6u23 (all tests were performed on the same Windows XP machine). The actual test client is very simple, the application is only a JFrame containing a JTextField and a JTextArea.
    The barcode scanner we use connects via USB and has no special driver. The scanner already decodes the barcode that was scanned and "enters" characters in the focussed text field of the test application by emulating the Alt+NumPad behaviour (the character '5' being produced by the equivalent of holding Alt and entering "0053" on the NumPad).
    Now, what appears when the application is run in JSE 6u03 is the expected result:
    5@WM010$|
    5@WM010$|
    5@WM010$|
    5@WM010$|
    Here's the result for the same barcode when the application is run in JSE 6u10 (results for 6u23 are similar):
    5@WÞ10ä
    é@—M010$|
    5@W¥ð104|
    5°ùM0ó(▄♀
    5@W¥010$|
    é@WM010Ü\
    é@W¥010P\
    5@wy010$|
    5@m01Ð$▄
    )°W¥01è$|
    )@—0ÑÐ$|
    Well, at least it manages to get some characters right every time... ;-)
    The character values are wrong already when the KeyEvent for each is being created and posted to the EventQueue. But on the other hand, the problem is obviously tied to the JSE used, so it has to occur somewhere after Java receives the input and before a KeyEvent is generated. Since the errors are very random, we are guessing that it might be a timing problem.
    Between JSE 6u3 and 6u10, KeyEvent has received some new members (here with their typical values for my use case):
    #isSystemGenerated     true
    #primaryLevelUnicode     0     
    #rawCode     0     
    #scancode     0     
    Maybe the problem could have been introduced in the same changeset? Or maybe the values observed are meaningful in a way?
    Can anybody enlighten me, or give me a hint of any kind? I already scoured the bug database but did not find anything.
    Thanks! Any help is appreciated!
    Regards, Lars

    @mriem: Yes, I did. In all cases, it is "windows-1252". And moreover, if it were a problem with the default character set, it would not show the random behaviour it does.
    I also managed to create a reproducer that shows the behaviour:

  • Making barcode scanner work

    Hello,
    I am stuck here with the barcode scanner "Symbol LS2208" via USB and have to use it in a Java app. I am using jdk 1.5 and downloaded the javax.comm API. Now i have some problems with which I hope one of you can help me. Is there a way to read from the scanner via USB, because as far as I can see the javax.comm API supports only serial ports and does the whole thing work with JDK 1.5, as javax.comm seems to have been written for JDK 1.2? I really would appreciate if one could get me started at least with some helpful documentation or examples...actually anything :-)

    I don't know about reading the USB input directly, and I don't know about your particular scanner.
    However, I have a Symbol LS4000 that I use in keyboard emulation mode. Is that an option for you? Or does it have to be the raw USB input?
    If you can use keyboard emulation mode, you'll probably have to configure the scanner to do that. For the one I have, the scanner gets configured by scanning various barcodes in the manual.
    So check with your prof or get the docs for the scanner. You'll need that as well as whatever Java knowledge is relevant for the approach you choose.

  • How would I create an USB Barcode Scanner Listener using Adobe AIR?

    I want to create a USB barcode scanner listener that would read in the scanned barcode, and place the barcode in a field in my AIR App even if the program wasn't focused on that particular field in the App.  If the client was using the application at the time for something else the scan would be buffered in AIR till requested or the AIR App has been idle for x period of time where upon the field would be brought into focus.
    How would I go about this (I'm developing on windows)  Was hoping for a USB solution within AIR but not fussy at all if I have to go outside AIR to solve this problem.  Java, Flex, ActionScript, Flash, C, C++, C#, VB (currently I've developed the rest of the App using Adobe AIR and JavaScript)
    I thought after some research that I could make a Java App (if all else fails) that listens and buffers the input and passes it along using a socket but JUSB doesn't work on Windows properly.
    I'm not stuck on any one particular implementation or idea just want to get development underway so...  Any ideas? or suggestions would be awesome.  I've googled a lot but haven't found any examples or solid suggestions, so any URL pointing to that information would be great too, if you know of a good one, then I'd be able to read up on any suggestion.
    Thanks,
    Marty

    Thanks Joe,
    Just for anyone else.  I bought a Metologic Scanner - VoyagerCG.  I was trying to get it to work using Java USB for a bit with no luck.  But if you get this scanner or one like it, it can be configured as a Virtual COM Port.  Which is very very easy in Java to set up as a listener and use sockets to transfer the data and listen within AIR.
    This PDF has links to drivers and instructions if this is useful to anyone.

  • How to identify the type of pocketpc barcode scanner?

    How to identify the type of pocketpc barcode scanner whteher it is intermec or symbol?
    GS

    Hi,
    well, this is the brand of the PDA - the Scanner itself is build into the device. So if you have an intermec device - you have an intermec scanner and vice versa. It is not recommended to use a HP device for example with an external scanner. This scenario is not really supported by the MI setup guides.
    Hope that helps!

  • I want to limit the number of scan done by a barcode scanner to 50, how can i do that

    I am scanning data from my 2d barcode scanner, now i want that after 50 scans my barcode scanner should prompt that scanning of 50 barcode complete, how can i do that? i know logic might be easy but its not sticking me. Please help.

    Hey,
    Everytime you get a valid scan increment a counter and compare with 50. If limit is reached you are done.

    best regards,

    The reason you're only matching two items is because you're reading the file one line at a time and applying the regex once per line. As Tim said, you can fix that by using while instead of if, but the real problem is much deeper: you're trying to write a scanner in the sense of a lexical analyzer, and that isn't what java.util.Scanner is for. I strongly recommend you start over, this time using Pattern and Matcher directly, not Scanner. If you happen to have a copy of MRE 3ed, there's an example of what you're trying to do on page 400. (Unfortunately, Friedl has just moved back to Japan, and hasn't had time to update the book's web site, or I could point you to the code online.) I don't have time to go into this right now, but you should pay particular attention to the find(int) method and the \G anchor.

  • Adobe form barcode scanner input

    I made an Adobe form with X Pro.  The purpose of the form is to inventory equipment.  I use a barcode scanner to enter serial numbers into the form.  When I scan the barcode (Code 39) of an item the serial number entered into the form is truncated.  To ensure that the scanner was reading the barcode correctly I scanned a code while having notepad open, it input the entire serial number correctly.  I did the same thing with Word and the serial was also input correctly.  Why is the form truncating my serial number?  I can type more in the field if I so wish so I know that a character limit is not the issue.  I checked all of the text box's properties but see nothing incorrect or limiting. 
    Thanks for the help,
    Goob

    Sorry for never replying to your post.  The problem is: I do not know why this is happening.
    Your last sentence "on the Text Area the scan seems to stop before entering all digits but when I scroll back through, they are accurate" makes me think.  As I wrote earlier, "A barcode scanner is basically just an input device like a keyboard", but very much faster.  Somehow it seems that the software acts like it is encountering the carriage return before all the data digits have been processed.
    But somehow it also seems to correct itself in a text area that allows multiple lines, but not in a single-line text field.
    Yet that does not happen with my barcode scanner, but with yours and the o/p's.
    Very confusing!  Does anybody else have some thoughts on this?

  • Error when importing java.util.Scanner

    Agh! I'm in an introduction to computer science course, and I am writing a program as an assignment that's due tomorrow.
    I have imported java.util.Scanner before, but I've only run it on the Windows PCs in the lab, whereas I am currently on a Mac. I've updated to the latest version of Java (through the software update), and I'm running Tiger (also fully updated).
    I'm using Dr. Java to write the programs, but I tried using the very same thing in Eclipse and it didn't work. Here's my program:
    import java.util.Random;
    import java.util.Scanner;
    public class Password {
    public static void main(String[] args) {
    //create a Scanner object to read from the keyboard:
    String password;
    Scanner scanner = new Scanner(System.in);
    Random randomizer = new Random();
    System.out.println("Please enter a string containing candidate characters.");
    String input = scanner.next();
    int charLength = length(input);
    System.out.print("Random password: ");
    System.out.print(input.substring(randomizer.nextInt(charLength)));
    System.out.print(input.substring(randomizer.nextInt(charLength)));
    System.out.print(input.substring(randomizer.nextInt(charLength)));
    System.out.println(input.substring(randomizer.nextInt(charLength)));
    And, here's my errors:
    4 errors found:
    File: /Users/brianmoore/Desktop/Password.java [line: 11]
    Error: cannot resolve symbol
    symbol : class Scanner
    location: package util
    File: /Users/brianmoore/Desktop/Password.java [line: 18]
    Error: cannot resolve symbol
    symbol : class Scanner

    File: /Users/brianmoore/Desktop/Password.java [line: 22]
    Error: cannot resolve symbol
    symbol : method length (java.lang.String)
    location: class Password
    Any ideas?

    Ok. I figured it out. On the Dr. Java page, this is what helped me:
    Please verify the following:
    - Open "/Applications/Utilities/Java/J2SE 5.0/Java
    Preferences";
    make sure "J2SE 5.0" is at the top of the list under
    "Java
    Application Runtime"
    - Open DrJava; go to Edit->Preferences; make sure
    "Tools.jar
    Location", "JSR-14 Location", and "JSR-14
    Collections Path"
    are all blank
    - Open the Help->About dialog box; make sure the "DrJava
    Version" listed is 20050601-0007 or later (that is, later
    than
    June 1, 2005)
    - Go to the "System Properties" tab in the
    "About" box; make
    sure "java.version" is 1.4.2.
    Let us know what you find out if you're still having
    trouble.
    Thanks for your help!

  • Barcode scanner interface

    We purchsed a HP barcode scanner with the intent of creating barcodes on items that need to be checked out and scanning them upon checkout, but we need a better way of displaying, when we scan mulitple items it just creates one long line of data.  Is there a way to get it to present better?  Perhaps a software program?

    Hello bdukart,
    An HP Barcode Scanner is a peripheral of an HP Point of Sale System. The only HP forum that discusses these items in on the HP Enterprise Business Community in the Discussion Boards.
    Here is the link to the specific area of that forum.
