Setup:Installation Guide/System Preparation/Windows/OpenJDK

Java is a prerequisite for the operation of Advanced Search, PDF export, VisualDiff (BlueSpice pro only) and the LaTeX renderer (BlueSpice pro only). The steps listed here are optional and only required if you plan to use one or more of these services in your BlueSpice installation.

Introduction

For licensing reasons, we decided instead of the Java Runtime Environment to use the alternative OpenJDK published under the GPL. Of course, you are free to use the JRE of https://java.com/, but here we only document OpenJDK.

Follow the further download instructions and download the ZIP archive to your hard disk.

Please note that the download on your Windows Server with Internet Explorer will only work if you have configured the Internet Explorer Advanced Security Settings in the Server Manager. Please refer to the technical documentation from Microsoft.
