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!
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.
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.
