Using barcode to input data

hi i want to intergrate a barcode scanner into my project but when i read the barcode from a word
document the data is not enterder into the textfield. how do i read a barcode and display the data in a jtextfiel?
how do i get this data after reading the barcode? thanks

What classes and methods do you have for reading the barcode? What do the method(s) return?
Once you have read the barcode's value into a variable, it should be easy to put that value into a textfield usign the JTextfield's methods.
