Unfortunately, at this stage, we don't have detailed information on getting SwiftRiver running on Windows systems.
However you can follow the *nix systems instructions and add your notes here as you go!
Notes
Java security keys
On Windows you might have issues with your maven compilation if your java is not using the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
Download and install them in case your maven is complaining.
Tomcat Class Paths
Also, make sure that your Tomcat is using the same Java Path as the one your your Path variable. Or else, the JCE issues above might persist.
