WinRun4J is an open-source, native Windows launcher and wrapper for Java applications. Originally hosted on SourceForge, its source code is maintained on GitHub.
The tool replaces the standard java.exe or javaw.exe launchers. It provides a way to deploy Java applications on Windows platforms. 🌟 Key Features
Custom Executable Name: Your program displays its own custom name (e.g., YourApp.exe) instead of a generic java.exe in the Windows Task Manager.
INI-Based Configuration: You define your application’s classpath, main class, JVM parameters, and application arguments inside a standard .ini configuration file.
Windows Service Wrapper: It can wrap a Java application to run seamlessly as a background Windows Service. It includes a helper class library (AbstractService) to handle standard Windows service events like start, stop, and pause.
Resource Embedding: Using its bundled tool RCEDIT.exe, you can inject the .ini configuration, splash screens, custom .ico icons, and even the .jar dependency files directly inside the executable. This lets you distribute your program as a single, standalone .exe.
Native Windows Bindings (PInvoke): WinRun4J includes built-in functionality modeled after .NET’s PInvoke. This lets your Java code call native Windows Win32 API functions and handle C-structs directly without writing any JNI (Java Native Interface) C/C++ glue code.
User Interface Enhancements: It provides pre-JVM splash screen handling with an auto-hide feature that triggers once the primary Java window opens. It also supports Dynamic Data Exchange (DDE) for standard Windows file associations and single-instance app checking. 🛠️ Basic Usage Workflow
