Cross-platform Java executable wrapper for creating lightweight Windows native EXEs. Provides better user experience.

Launch4j is a cross-platform tool for wrapping Java applications distributed as jars in lightweight Windows native executables. The executable can be configured to search for a certain JRE version or use a bundled one, and it's possible to set runtime options, like the initial/max heap size. The wrapper also provides better user experience through an application icon, a native pre-JRE splash screen, a custom process name, and a Java download page in case the appropriate JRE cannot be found. http://launch4j.sourceforge.net/

Pinning a Java application to the Windows 7 taskbar

I use Launch4j as a wrapper for my Java application under Windows 7, which, to my understanding, in essence forks an instance of javaw.exe that in turn interprets the Java code. As a result, when attempting to pin my application to the task bar,…

I'm using Launch4J to start my Java application and if an x64 JRE is present on the system, Launch4J seems to prefer it. Unfortunately my application cannot run on a 64 bit JVM because I'm loading a 32 bit DLL, which is not possible and leads to an…
