Running a "JAR" File
Java is a programming language and computing platform that powers a large share of today’s digital world by providing a reliable platform upon which services and applications can be built. OpenRocket is one of these, and it will not function unless you have Java installed.
Java is enhanced to improve performance, stability and security of the Java applications that run on your machine, and a new feature-release is issued every six months. And, every three years, an issued release is designated as Long-Term Support (LTS) and receives quarterly security, stability, and performance updates only, meaning the version does not changed when updated. To ensure the broadest possible compatibility and stability of the application, OpenRocket is intended to be used with Java LTS versions.
The OpenRocket installers are packaged with the correct version of Java for the OpenRocket version being installed, such that everything that OpenRocket needs to function correctly is installed during the installation process; the Java version installed on your device is ignored. So, the easiest and most reliable way to use OpenRocket is to skip the .jar installation, and, instead, use the packaged installers for your device. The use of a .jar version is not recommended.
2022 Beta Release
Although Java 17 (LTS) was released in September of 2021, beta development had progressed too far to provide for its full compatibility. The 2022 beta release of OpenRocket requires the Java 11 (LTS) platform to fully function correctly; OpenRocket 2022 beta releases are not intended to run with any other version of Java at this time.
- Download OpenRocket 22.00.beta.01.jar (INACTIVE UNTIL RELEASE DATE)
- Copy it to a convenient folder.
- Make the .jar file executable (if needed).
- Start OpenRocket by either double-clicking the .jar file, or right-clicking the .jar file and selecting "Open".
You man also start the .jar OpenRocket from the command line, replacing "/path_to/" with the path to the .jar file on your system:
java -jar /path_to/OpenRocket-22.00.beta.01.jar
Version 15.03
OpenRocket 15.03 requires the Java 8 (LTS) platform; OpenRocket 15.03 may not function correctly using any other version of Java.
- Download OpenRocket-15.03.jar
- Copy it to a convenient folder.
- Make the .jar file executable (right-click on .jar file, select "Properties", go to the Permissions tab and check the "Allow executing file as program" box).
- Start OpenRocket by either double-clicking the .jar file, or right-clicking the .jar file, and selecting "Open with Sun Java6 Runtime".
If the default is set to open with the Archive Manager, then right-click, select "Open with other application", then select "Open with Sun Java6 Runtime", and check the box to make that the default. In future, it should be possible to just double-click to start OpenRocket.
Alternatively you may start OpenRocket from the command line:
java -jar OpenRocket-15.03.jar
Or, if you are not currently in the same directory as the .jar file, replace '/path_to/' by the appropriate path on your system:
java -jar /path_to/OpenRocket-15.03.jar
