Using Barcode reader in java

Hi,
I have a project in which i have to read barcodes from a smart card
and then find out the id to which it belongs. I have the barcode values
and corressponding ids. I am not familiar with barcodes. Can anyone
please tell me how to use java for this purpose? Is there any java API
for that.
Thanks

bond303,
Sounds to me like you have the information from the device and your
asking what to do with the data you have.
By the sounds of things your using EAN barcodes, but who knows which
one. Can you post a sample barcode please and can you look up the
specs for the client your doing the work for. They will state what
Symbology they are using.
Of course if your doing this inhouse then you must have a department
that has specified requirements for the structure of the barcode.
Either that or your attempting to use a Smart Card from another
vendor. If the later then you need to contact that vendor and find out
what standards they are using.
I presume again it will be some sort of EAN style standard. If theyre
just replicating a barcode on the Smart Card then I would imagine it
will be EAN128, otherwise it could be anything.

BarCode scaners in Java Application

Hi,
i m interested in learning how to interface BarCode Scanners in Java application
can ne one give me code snippest for the same ?
i want the scanned value to appear on the selected JtextField..
please help me out..
Thanx in advance
Bye

All the barcode scanners I've used have been treated as keyboard input by the pc. So no special handling is needed to get the barcode into the textfield. If you want it to appear as a barcode in the field, change the font in the field.
When in doubt STFW:

I'm sorry, but I'm not able to answer this question. My purpose is only to add a question.
-->Is it possible (perhaps Java Beans) to write word documents in the web environment?
-->Another question: Is it possible to get the username and passwort with which the user is logged on onto windows? Do you have an example? All these questions belong to the web environment

How to read the Java source code (in Netbeans)

I use OS X10.5.5, NetBeans 6.1 and JSE 6 on a 64 bit mac.
When I downloaded NB6.1 it had JSE 5 as it's default (and only) java platform. I ran Software Update to get Java 6 from Apple, used the Java Prefrences utitlity to set JSE6 as default. In NB I added the JDK6 platform, registered the JDK6 javadocs and noticed that I also have the option of registering the Java source code.
I have three questions:
1) How do I make JDK6 the default in NetBeans. The JDK5 keeps being default after I did the steps above and I don't see anywhere to change that.
2) How do I read the Java 6 source code? I can see sun provides [source code| http://download.java.net/jdk6/] for their supported platforms. I dont see Apple doing the same for its JDK port. What would I need to do to get to read the java SE6 sources? or is it actually hiding somewhere in the /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home hierarchy?
3) Where does the JVM look for the binary code to run when I make a call to, say java.util.ArrayList or any other library. In my naivety I would have assumed it would be a .class file somewhere in the java Home folder, but I don't see anything like it.
thanks in advance,
chris

This is taken from the help included with netbeans. In response to question 1.
By default, the IDE uses the version of the Java SE platform (JDK) with which the IDE runs as the default Java platform
for compilation, execution, and debugging. You can view your IDE's JDK version by choosing Help > About and clicking the
Detail tab. The JDK version is listed in the Java field.
You can run the IDE with a different JDK version by starting the IDE with the --jdkhome jdk-home-dir switch on the command line
or in your IDE-HOME/etc/netbeans.conf file. For more information, see IDE Startup Parameters.
In the IDE, you can register multiple Java platforms and attach Javadoc and source code to each platform. For example, if you
want to work with the new features introduced in JDK 5.0, you would either run the IDE on JDK 5.0 or register JDK 5.0 as a
platform and attach the source code and Javadoc to the platform.
In , you can switch the target JDK in the Project Properties dialog box. In , you have to set the target JDK in the Ant script itself,
then specify the source/binary format in the Project Properties dialog box.
To register a new Java platform:
Choose Tools > Java Platforms from the main window.
Click New Platform and select the directory that contains the Java platform. Java platform directories are marked with a
in the file chooser.
Use the Sources and Javadoc tabs to attach Javadoc documentation and source code for debugging to the platform.
Click Close.
To set the default Java platform for a standard project:
Right-click the project's root node in the Projects window and choose Properties.
In the Project Properties dialog box, select the Libraries node in the left pane.
Choose the desired Java platform in the Java Platform combo box.
Switching the target JDK for a standard project does the following:
Offers the new target JDK's classes for code completion.
If available, displays the target JDK's source code and Javadoc documentation.
Uses the target JDK's executables (javac and java) to compile and execute your application.
Compiles your source code against the target JDK's libraries.
If you want to register additional Java platforms with the IDE, you can do so by clicking the Manage Platforms button.
Then click the Add Platform button and navigate to the desired platform.
To set the target Java platform for a free-form project:
In your Ant script, set the target JDK as desired in the javac, java, and javadoc tasks.
Right-click the project's root node in the Projects window and choose Properties.
In the Sources panel, set the level of JDK you want your application to be run on in the Source/Binary Format combo box.
When you access Javadoc or source code for JDK classes, the IDE searches the Java platforms registered in the
Java Platform Manager for a platform with a matching version number. If no matching platform is found, the IDE's default platform is used instead.

How can I get data from barcode reader to forms

Hi Experts,
Forms 6i
I would like to gather data from barcode reader.
Any idea if you got please share.
Thanks in advance.

Hi,
I think its working same like keyboard. Either you type the code manually or you can read it from scanner. With the help of keyboard you can able to type anything on the cursor position, on the same way the barcode-scanner is also working. Just like a copy and paste the scanner copies the data from physical device and paste it into your corrent cursor position. There is no separate program codings needed for this job.

Keyence Barcode Reader & RS-232

Hey gang! Just wondering if anybody out there has successfully communicated with a Keyence BL-600 series barcode reader (or any Keyence barcode reader for that matter, I'm desperate) via RS-232.
I have a BL-601 and I can communicate with it when I'm using Keyence's software, but I can't get it to do anything through LabVIEW.
I've tried using the Instrument I/O Assistant and coding it the "low level way" and I'm just not getting anywhere with it so I decided I would throw my problem into the internet tubes and see what happens....
Thanks!
-- Jason

Communicating with a barcode reader over RS232 is the same as communicating with any RS232 device. You should first verify that you can communicate with it by using HyperTerminal if you're on Windows, or your favorite terminal program if you're using another OS. Next, call up the "Basic Serial Write and Read" example that ships with LabVIEW (Help->Find Examples). Set up the communication parameters as you need. In your case you probably want the "write" off. The VI is not set up to run in a loop so you will need to scan first then run the VI to get the data off the serial port buffer.
One suggestion: can you use a keyboard wedge with this reader instead? This would make it so that the string you scan would be as if you had physically typed it via a keyboard, and the application wouldn't know the difference.

Barcode reader input to string control

Hi,
I am using a barcode reader that uses keyboard emulation. The barcode types on the computer the same way a keyboard would. When I open notepad and use the barcode reader to read a barcode, the following meesage is typed:
S/N: 17967
Lin: 0.591%
Ph: 1.32deg
In that exact format. However, when I try use the reader in labview with a string control the format changes. The following meassages are printed instead:
S/N: 17967mn: 0.591%m: 1.32deg
S/N: 17967mn: 0.591%mn: 1.32deg
S/N: 17967mnLin: 0.591%mPh: 1.32deg
S/N: 17967mn: 0.591%m:1.32deg
So the format changes. Sometimes the Lin and Ph are printed other times they are not, spacing in the string changes, and in all cases the carriage return is no longer there.
Could you please let me know what might be causing this. Ideally I would like the message to be read in the same format it is in notepad. My code is attached.
Thanks

Is there a reason you have a timeout event? You are not doing anything in there. So I would remove the timeout (you can just remove the timeout input or set it to -1).
I'm just thinking that if you set the focus while the scanner is doing its thing is causing the issue you are seeing.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Using the Barcode Reader with QR codes

Manchester Art Gallery is trialling QR codes in its Remembering Slavery: Revealing History display. From 1-29 March visitors will be able to use their mobile phones to retrieve specially designed web pages. The pages invite visitors to submit comments on six works on show, and listen to and read poems and comments on some of the objects.
More information on the display is at http://www.manchestergalleries.org/whats-on/community-programmes/current-projects/
The project was initiated by Julian Tomlin, a freelance consultant who is undertaking a review of machine-readable technologies in museums for a consortium of London museums.
Come to the Gallery on Moseley Street, Manchester and try out your phone. The N95 includes a barcode reader. On Saturday 1 March there will be people on hand to offer some guidance. Let us know what you think of this emerging technology.

If your phone doesn't have bar code reader. This one works great for me:

Barcode reader not working on E71

Hello,
how we can use barcode reader in e71 its not woking.
Solved!
Go to Solution.

Can you give some further detail about your problem please.
For example:
Is it not working as the application will not run or crashes?
or
Is it not working as it will not scan any codes that you try?
Make sure you are scanning the correct type of barcode as it does not scan traditional barcodes that you find on most products in shops. There would be little point in scanning those. It scans 2D barcodes which contain extra information such as weblinks or contact cards. You can find examples of 2D codes by searching google.

How do you identify a key events source (std keyboard or a USB barcode reader emulating keyboard)?

I have attached a USB barcode reader which essentially emulates a USB
keyboard. Having looked through the VC++ V5.0 documentation and some SDK
documents that I have, I could not find a library function that identifies
what device sourced the keyboad event.
Does know if this is possible ? Anyone have any ideas ?
Thanks.

If you over ride the "CWnd:reTranslateMessage" function you'll be able to trap keyboard messages.
ex:
BOOL CTestexecDlg:reTranslateMessage(MSG* pMsg)
if (pMsg->message == WM_KEYDOWN && (pMsg->wParam == 13 || pMsg->wParam == VK_ESCAPE))
// Enter or escape key was pressed; return TRUE to stop default handling
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x30)
BringWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x31 && m_DisplayObject1 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject1->SetWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wPa
ram == 0x32 && m_DisplayObject2 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject2->SetWindowToTop( );
return TRUE;
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == 0x33 && m_DisplayObject2 != NULL)
// Enter or escape key was pressed; return TRUE to stop default handling
m_DisplayObject3->SetWindowToTop( );
return TRUE;
return CDialog:reTranslateMessage(pMsg);

Error: cannot read HelloworldApp.java

Hello
When I compile the HelloWorldApp.java program. I have this problem:
I get: error: cannot read HelloworldApp.java. What can I do?
In addition, How do I use the options? For example:
javac -g HelloworldApp.java
I get an error saying that I did not use well the flag g. Is the command bad written?.

You post has different capitalization of the program name:
". . .compile the HelloWorldApp.java program. I have this problem:
I get: error: cannot read HelloworldApp.java.
Java is case-sensitive, make sure to capitalize correctly.
Open a cmd/command window in the directory that contains your .java file and do a "dir helloworldapp.java" command to verify the file exists with the correct name.
Read the documentation for the javac command to learn how to use the command options.
