Opaque qr code not showing?

I am trying to show a barcode on a webpage. All encoders are displayed except for the QR code. I read that two jar files are needed for this. sample
  • barcode4j: 2.1
  • qrgen: 1.4

I added these jar files to lib folder and try to run it. So I get 404 error when I add qrgen to lib folder.

I tried to do it using maven and added a dependency like this:

<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 am getting error for the second dependency, so I copied the barcode4j file to the lib, but I cannot print the QR code. Help me help.

I think you are doing fine. But you missed one thing. The qrgen-1.4 you are using has the following dependencies, zxing-core-2.0 and zxing-javase , trying to include these two jar files in your build path they might work well.
