I am using primefaces to develop a web app.I am trying to show the bar code on mhe webpage.All coders are shown except the QR code.I have read that two jar files are required for this sample

barcode4j: 2.1
qrgen: 1.4

I have added these jar files in the lib folder & try running it.In this way i get 404 error when i add qrgen in lib folder.

I tried doing it using maven i added the depedency as follows:

<dependency>
    <groupId>net.glxn</groupId>
    <artifactId>qrgen</artifactId>
    <version>1.4</version>
</dependency>
<dependency>
    <groupId>net.sf.barcode4j</groupId>
    <artifactId>barcode4j-light</artifactId>
    <version>2.1</version>
</dependency>

but i get error for second dependency so i copied the barcode4j in lib folder but i can't print the QR code.please help me out.

I guess you're doing all ok.But you missed on one thing.The qrgen-1.4 you are using are further having dependencies as zxing-core-2.0 & zxing-javase trying including these two jar files into your build path these might work well.
