About OpenWebStart

Java Web Start (JWS) was deprecated in Java 9, and starting with Java 11, Oracle removed JWS from their JDK distributions. This means that clients that have the latest version of Java installed can no longer use JWS-based applications. And since public support of Java 8 has ended in Q2/2019, companies no longer get any updates and security fixes for Java Web Start.

OpenWebStart is an open source reimplementation of the Java Web Start technology that provides the most commonly used features of Java Web Start and the JNLP standard, so that you can continue using applications based on Java Web Start and JNLP without any change.

#### Custom configuration

If you wish to use your own [`response.varfile`](https://openwebstart.com/docs/OWSGuide.html#_unattended_installation), use the `config` package parameter:

`choco install openwebstart --param '"/config:(path to file)"'`

## Java required!

**OpenWebStart will install without Java, but a version of Java must also be installed to run JNLP files.** [Choose your flavor](https://community.chocolatey.org/packages?q=openjdk).
