JARStarter (formerly known as Hitonic JAR-Starter) is a lightweight Windows utility designed specifically for software developers and power users who need to run Java (.jar or .jad) executable files across multiple Java environments on a single PC. What is JARStarter?
When you have multiple Java environments installed on your machine—such as various versions of Java 2SE (JDK/JRE) or Java 2ME mobile emulators—Windows default behavior typically launches any double-clicked JAR file using whichever Java version was installed last.
JARStarter solves this frustration by allowing you to select your desired Java runtime environment on the fly. It integrates directly into the Windows Explorer context menu, letting you right-click any JAR or JAD file to pick exactly which environment should execute it. Key Features & Capabilities
Automatic Detection: It automatically scans your computer to detect installed J2SE and J2ME runtime environments, eliminating manual path configurations.
Manual Profiles: You can manually add custom Java starters by specifying the executable item path, file name, and specific runtime arguments.
Shell Integration: The tool builds file associations with Windows Explorer so you can manage and execute files directly from your desktop or folders.
Environment Management: It features a clean, dual-panel user interface where you can easily build, copy, edit, or delete lists of your distinct environment profiles. Hands-on Review Consensus
The Pros: Tech reviewers highlight that the application is incredibly lightweight, intuitive, and highly functional for developers testing applications across legacy and modern Java environments (like JDK 1.4 vs JDK 1.5). It requires minimal setup effort.
The Cons: The software is an older legacy utility. Independent testing by software repositories like Softpedia noted minor stability bugs on newer versions of Windows, such as occasional application freezes when attempting to force manual file associations. It also lacks a built-in help manual, though the parameters are straightforward enough for its target technical audience. Free Download Options
