Wiki - 1.8 Import Certificate

Compatibility

This tutorial will demonstrate how to import the certificate that is supplied with the free version of qz-print into Java, and how to properly load the applet within the browser. These steps will allow the sample.html page to properly display.


How to Import Certificates into Java

This section applies to the free version only. Premium versions don't need to import a certificate, as it's already trusted.

Extracting the Zip File

The certificates must be extracted from their zip file before they can be imported into Java.

  1. Open up the file

  2. Unzip the file qz-free certs.zip by extracting it to a desired location. In this example, we are extracting the files to the same directory.

    Codebase Parameter

    If this dialog persists after after checking the "remember" checkbox, it's due to new security requirements in Java rquiring a codebase parameter which requires recompiling.

  4. After hitting allow, the webpage should turn from pale yellow to gray. If your page is displaying properly, it will look like the image below.

    Note: If at anytime the Java screen prompts do not appear, check your task bar for a Java icon. image

That's it. At this point, the applet is properly running in your browser and you are ready to move on to Getting Started tutorial, which demonstrates the code behind qz-print.
