Bar Code in Java ?
I had developed a site and this site needs to suport bar code.
Somebody knows how do i do Bar Code in Java ?
Sorry about my english.
I'm trying to print labels with bar codes myself.
The solution will depend on the bar code printer you're using. The one I've got, Intermec, ONLY understands its own proprietary print protocol, IPL. So my Java app has to generate IPL in a byte stream and send that to the print queue.
I'm still working on it, so I can't claim 100% success, but I'm using javax.print API to get the byte stream to the queue. I KNOW that works. It's just getting the IPL right that's still a problem.
I had to get a UI tool to help me develop labels graphically and then have it spit out the IPL for me.
This might be representative of the path you'll have to follow. - MOD

How to programming bar code by java?
hi,
Does anybody know how to write programming to translate the charactor( such as num or char) into bar coding and how to translate the barcode back into charactor by java?Hello,
Is it possible you could post all of teh object code for printing bar codes? Thanks.
Ok ... it's been about 4 years since I'd written this,
so there may be better ways of doing it now
(especially since jsk1.4 now allows you to draw
directly to screen!)
1) I created an object extending Canvas
2) In my paint method, I needed to draw the code & the
numbers below the code:
public void paint(Graphics g)
// calculate text length & draw the barcode
num = text.length();
length = ((3*wide)+(6*narrow))*(num+2) +
+ (num+1)*seperate;
DrawBarcode(g);
3) In the DrawBarcode method
I drew rectangles where I needed the barcodes (ie:
g.fillRect) - making sure that there was spacing
required ... which depends on the barcode you're
using.
Do you have any specific questions? -
How to read card reader (bar code reader) in simple java program ?
hai all
how to manipulate (read/write) card readers (or bar code reader ) in
a java program ?
should i import any particular package library ?
pls give me any sample code or tutorials or tools, etc (whatever you have) .
i am new to this card reader category
its very urgent
thank you .Nearly all card readers and barcode readers I've ever seen simply stick their input right onto stdin, so you can capture it just as if it had been typed in on a keyboard

How to implement bar code font in BIpublisher?
I have pasted bar code font file in c:\WINDOWS\font(true type) location,
then i pasted bar code font file in many folders viz.C:\Program Files\Java\jre6\lib\fonts and also in
C:\Program Files\Oracle\BI Publisher\BI Publisher Desktop\Template Builder for Word\fonts ....
i have made changes in XDOEXAMPLE.CFG to rename it to XDO.CFG after changing fontfamily and
truetype path as
<font family="IDAutomationHC39M" style="normal" weight="normal">
<truetype path="C:\jre6\lib\fonts\IDAutomationHC39M_Free.ttf" />
</font>
i have also installed bar code font which i can get in MICROSOFTword but when i preview the template then i get a javaioexception error saying it cannot find the path
plz help me asapuse xmlpublisher if your oracle version is supprting. Download the font from IDautomatiion,
else you can also directly incorporate in your report. Here are the steps:
1. Download and install the font on the machine that Reports Builder and Server will be running.
- Windows is a simple matter of copying the IDAutomationC128M.ttf to the C:\WINNT\fonts directory.
- Unix is very complex. Use the following note to assist in installing the font:
a. Set the DISPLAY environment variable to the expected final IP Address that
the Reports Server will be using. Every time the DISPLAY is set to a different
IP Address, the available fonts will be different.
b. To capture the results of the commands, use the "script" utility.
In any directory that you have write permissions, do the following:
#script fonts.trc
#echo $DISPLAY
#xset -q
#xlsfonts -u|grep iso8859-1
#exit
c. You also need access to the uifont.ali found in:
Developer 6i: $ORACLE_HOME/guicommon6/tk60/admin
Developer 9i: $ORACLE_HOME/guicommon9/tk90/admin
2. Create the report and reference the new barcode font.
3. Verify that the output displays the barcode.
4. Attached the IDAUTOMATION.pll that is downloadable with this note.
5. Edit the Property Inspector for the field.
6. Create a format trigger the encodes the value:
Example:
function F_barcode1FormatTrigger return boolean is
begin
srw.set_field_char(0,idautomation.code128b(:barcode1));
return (TRUE);
end;
7. Compile and close the trigger.
8. Now the barcode is encoded with start and end codes. -
Bar Code Font 3 of 9 cause NULL pointer exception in PDF export

Is there anything that I did wrong or is it generally not working with CR4E to use a simple barcode font?
When I use ReportExportFormat.MSWord or ReportExportFormat.crystalReports it works fine but unfortunately
out customers insist on PDF. Any help would be appreciated very much.
The bar code font I am using is from http://www.barcodesinc.com/free-barcode-font/
Edited by: Lothar Bernecker on Dec 3, 2009 3:12 PMI think there's issues with that Barcode TrueType font and Java.
You can try a Java app (such as the sample demo app that comes with Java) and try viewing that font.
You'd need to use a different barcode font.

Is Oracle Form can read bar code scanner ?
Hi everybody,
I would like to develop an application for a video club with oracle form. Can anyone tell me how can do or just say if it is possible or not
Thanks a lot.
Shafique MahmoodI would like to develop an application with
Oracle form can any one can just tell me
is it possible or not? Depending what bar code scanner you use. If it has a Java
interface, you can develop a PJC (Pluggable Java Component) for
Forms, or even a Java Bean and use a JavaBean area item.
If it has a COM interface, you can use the JavaBean/COM bridges
probably get the same result.
For PJC and JavaBeans, have a look in the Forms 6i/9i docs for
more info.
Hope that helps -
How to integrate Barcode scanner with java application?
The most bar code scanners I used (about half a dozen variations) got plugged between keyboard and computer and just produced normal keyboard events. So there was no need for a special api .. you actually could go into notepad to read whats in the barcodes.
There are more complex scanners though, coming with a build in display an own os and all kind of stuff ... for those you'll get an API from the producer of the scanner. I'm pretty shure they have all java apis by now

Bar code font in Report server 10g
Hi

Dhanawhich fonts i should use in printing the Report in Network printer under AIX Environment.No idea, I don't work on AIX. Try this site:

2D bar codes are not supported in Reports. You will need a Java solution. See this thread:

This thread also has the suggestion to create the 2D bar code as an image. Of course, you still need some other program to create this image first. -
Incorporate Bar Code in Oracle Reports
Hi,
I want to incorporate Bar code font in character based oracle reports.Kindly let me know how to go about implementing it.Secondly is there any site from where i can download the bar code fonts freely.Also does Oracle provide Barcode fonts for Oracle Reports.
Thanks in advance
Deepakhello,
from your question i understand that you want to create a barcode in a character mode report. this will be very difficult as it requires the destination printer to be able to print barcodes. a barcode font will not help here, as charactermode reports do not leverage fonts other than ones available in the printer.
usually it is more to creating a barcode than just printing the value in barcode font. most barcodes need special algorithms to create chechsums and similar stuff.
you might want to look into our barcode example that shows you how to use a java bean to generate a barcode.
http://otn.oracle.com/products/reports/htdocs/getstart/examples/BarcodeBeanPaper/index.html
oracle does neither ship barcodefonts nor java beans to generate barcodes for production purposes. the supplied sampels are for demo purposes only. however there are several commercially available fonts as well as javabeans on the market.

JDev3.1;Print; Bar Code Font?
Hi there,
Is there any Bar Code font integration for
JDeveloper?Fonts can be integrated into a JVM by following the instructions provided (editing font.properties).
You may find barcode font vendors from various sites including: http://www.componentsource.com
which lists: JBarCode1, JBarCode2
...JBarCodePro2 is a JavaBean component that supports Java 1.2.X and higher. Users can use JBarCodePro2 in any IDE that supports JavaBean to develop advanced barcode applications. JBarCodePro2 can also be used in the web server to display barcodes on web browsers dynamically
I hope this helps,

About the bar code report in printer server
Hi:
I have a question about the bar code report in printer server, i can do the bar code report in my local computer ,
but it can't be work when put it into the printer server ,
It would be get the error message :
REP-110: can't open the file 'null'.
REP-1070: it have a error when it open or sqve the document.
REP-0110: can't open the file 'null'.
I had study the document orbr_barcode.pdf before,
and I do something below:
1. copy a new oraclebarcode.jar into my computer.
2. change the regedit HKEY_LOCAL_MACHINE\SOFTWARE\ORACLEHOME1\REPORTS_CLASSPATH,
add a new path that the oraclebarcode.jar was.
3. import java class
oracle.apps.barcode.util.BarCodeConstant
oracle.apps.barcode.BarCodeMaker
4. new PACKAGE globals IS
bcobj ora_java.jobject;
barcode_to_use varchar(256);
tempdir varchar(100);
directory_sep varchar(2);
END;
5.modify function BeforeReport return boolean is
begin
globals.barcode_to_use := BarCodeConstants.BAR_CODE_39;
globals.bcobj := barcodemaker.new();
return (TRUE);
end;
6. new Formula in the DataModel, and set to image,
function CF_barCodeFormula return VARCHAR2 is
myfilename varchar2(500);
result varchar2(500);
barcodeData VarChar2(500) := :ast_no;
begin
myFileName := srw.create_temporary_filename;
barcodemaker.setBarWidthInch(globals.bcobj,0.005);
barcodemaker.setBaseCodeData(globals.bcobj,barcodeData);
barcodemaker.setBarCodeType(globals.bcobj,globals.barcode_to_use);
myFileName := barcodeData;
barcodemaker.setFullPath(globals.bcobj, myFileName);
barcodemaker.renderBarCode(globals.bcobj);
return(myfilename);
end;
It's success when I build a bar code report in local computer,
but I copy the oraclebarcode.jar into printer server and chage the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLEHOME1\REPORTS_CLASSPATH, but it get the error message ...
Please help me , I try it so many times and it still fail,
your sincerely ,

Why does the bar code look "chubby" when I save to PDF?
Hi, I'm designing a book cover for a client in Illustrator, and it has a bar code on the back of it. When I save the file as an .ai or a .png or .jpeg, it appears fine. But when I save the file as a .pdf (which my client will be viewing, and for print), the bar code looks like the lines have gotten bigger or run together! It's really weird...no matter which preset I use, it appears like this (I've attached a screenshot). I've also tried the "flatten transparency" and converting the numbers to outlines, but they still tend to distort when the pdf is viewed.
Any suggestions on how to fix this, or why this might be happening? It scares the client when they see it....
The lines in the picture are MUCH thicker than the actual bar code, and some appear to have blended together.Hi Mike,
In the Preferences area of Adobe Reader, go to the Page Display tab, and
make sure that "Enhance thin lines" is unchecked. That seemed to solve
most of my problems with the type! Hope that works for you too!

Bar Code Scanning for Windows Phone 8.1
Hi,
I need to find proper way how to scan bar codes in Windows Phone 8.1 or in universal app. I found out that there is native class BarcodeScanner available only for client apps and not for WP. I also find 3rd party library zxing.net, which is not working very
well on WP 8.1. I have done really deep research, but I have not found any single working solution for WP 8.1, so I would like to ask for your help in finding of library with which I will be able to scan barcodes on WP 8.1.
Thank you.If you don't need a universal App you could build a Silverlight 8.1 App and use the old Camera APIs which work nicely with ZXing.Net. I have done so myself.
As for Windows 8 and Universal Apps - you would have to implement a CustomSink for the Video Stream, extract Frames from there and pipe those though a recognition library. So far there seems to be no ready made solution that offers this.
So right now using the old APIs would be my suggestion.
Maybe you are looking for
