Question

If I am understanding correctly:

It will allow me to send an embedded JRE along with my JAR so that my jar works whether or not the user has Java installed on their computers.

I have never worked with it before so I thought I might ask before going on a steep learning curve :)

Was it helpful?

Solution

Launch4j does not embed the JRE. It is a wrapper for your JAR file which checks for an appropriate JRE installed on the target PC, and if it is not installed it will offer the user to download it.
