Java Webstart

With the following command the Java Webstart cache can be made empty: javaws -clearcache -uninstall

Security: macOS

Because the JAR files from this Java Webstart application have been signed with an official Comodo certificate, the application can be started without any annoying security warnings.

Specific for macOS the following steps must be made to successfully start the application:

  • Click on icon, JNLP file is downloaded

  • Do not click directly on the downloaded JNLP file! Instead, open the Download directory and click with right mouse button on Open or Open With

  • Confirm it is OK to open the JNLP file
