Java archive .jar

What is Java archive?

A ZIP-based package of Java resources. Conversion extracts contents without executing code.

Server conversion requires a compatible engine we host and a verified file variant.

Technical details

JAR is a ZIP-based archive with optional META-INF metadata and a manifest that describes Java classes, resources, and entry points. [1]

Background and compatibility

Oracle's JAR specification builds on ZIP, so ZIP tools can inspect entries while Java tooling interprets manifests and signing data. [1]
