With the [RedisGears JVM plugin](https://github.com/RedisGears/JVMPlugin), you can write RedisGears functions in [Java](https://en.wikipedia.org/wiki/Java_(programming_language)) and run them on a [Redis Software](https://redis.io/docs/latest/operate/rs/) cluster. It currently supports [JVM](https://en.wikipedia.org/wiki/Java_virtual_machine) version 11.

Similar to the Python plugin, the JVM plugin allows both batch processing and event-driven processing.

Before you can run RedisGears with Java, you will need to [install the RedisGears module and the JVM plugin](https://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/deprecated-features/gears-v1/installing-redisgears#install-redisgears) on your Redis Software cluster and [enable them for your database](https://redis.io/docs/latest/operate/oss_and_stack/stack-with-enterprise/deprecated-features/gears-v1/jvm/install).

Once you have written your code, compile and package it into a [JAR](https://en.wikipedia.org/wiki/JAR_(file_format)) file and upload it to a node on your Redis Software cluster. Use the `RG.JEXECUTE` command with the `redis-cli` command-line tool to run your code.
