I want to create barcodes and read it in java.
Id read about this but im not sure what to use.
For now, i'd read about Java Barcode API and BarcodeImageHandler.
Can anyone give me an advice to learn more about this?
I dont know if it have relevance but im using the NetBeans 7.1.2 IDE
Try using ZXing alongisde this tutorial or you may be able to download a Barcode Font such as Code38 or IDAutomationHC39M and use this within you document.

anyone can help me to share a code for using this file in JavaCv I will be grateful.(Need code to put image on it and guess the feeling with this xml file.)

I use CascadeClassifier From the package org.opencv.objdetect.CascadeClassifier and I think miss some point.

I need to replace a specific text or tags in a PDF file and save it.
I tried, iText, PDFBox and other libraries, but nothing works correctly.
Currently am going to use Sejda SDK but I cannot find the code which actually does the replacement.
They have this functionality working in the Desktop app. and in the web app. but I have to dig in the code to find it.
Can any one help please? and thanx in advance.
That is not part of the open source SDK.
I need to create an app (using Android Studio) that generates CNC code to operate a 3D printer. It takes a String as input.
I've found a couple libraries in Python and Javascript that does this, but as I don't have time to translate whole libraries to Java, can you recommend any libraries that does that for me? If there are no open-source options, can you recommend any guide to help me develop this conversor?
What we ended up doing:
App asks for a String as input;
String is converted to a bitmap and then saved as a .png;
.png is loaded and converted to a .svg file. We used this repo: https://github.com/jankovicsandras/imagetracerandroid
We developed a parser to convert a .svg to g-code.
It worked but it's not the best solution, we're looking to implement something that runs python in Android, as there are many pythons that do all the work already, but that's how we've done it and it's working by now.
How to extract handwritten text from images, like bank form images, in Java?
I tried to using Tesseract, OCR, GOCR but didn't working for me. Are there any other ways to extract handwritten text from images in Java which works at least 80-90%?
Question with links to libraries
I don't think JAVA natively supports this function, so you gotta use libraries.
There was a question which asked for working libraries and the general consent was: you won't get a 80-90% working recognition in a free and open source library.
Anyway, you can try this, as it is a wrapper for Tesseract.
I want to recognize the barcode from the image file using Java, but I am a beginner to development. So I do not have any idea on this. Please help me.
http://code.google.com/p/zxing/ has a very nice api for scanning barcodes in various formats
if you are interested in decoding a barcode yourself, have a look at this processing example
i have written a while ago

The following links may help you. Check them out.

EDIT after 1st comment:
To get barcode from file, check the following link:
Java Barcode API
Java Barcode generator
Asprise commercial library is the best solution
You have other alternate which can be useful
