ej-technologies GmbH

ej-technologies GmbH is a German software house that has spent more than two decades refining tools for Java deployment and profiling. Its best-known utility, exe4j, distills that experience into a single, focused mission: turning cross-platform Java programs into first-class Windows citizens. With exe4j 9, developers point the wizard at any JAR collection, optionally bundle a private JRE, and receive a compact native launcher that handles splash screens, icon embedding, service registration, 32- or 64-bit selection, and flexible classpath resolution without forcing end users to touch the command line. The generated executables integrate cleanly with Windows Task Manager, UAC elevation, and MSI installers, so corporate IT departments can distribute Java line-of-business tools the same way they ship C++ applications. Independent software vendors rely on the same process to wrap microservice clients, database front-ends, or data-science notebooks into a single branded EXE that can be code-signed and updated through existing Windows channels. Because exe4j preserves the original bytecode, developers keep the write-once philosophy of Java while gaining the look-and-feel expectations of Windows consumers. The publisher’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the newest release and supporting batch installation alongside other applications.
