I'm trying to test if my browser can detect if javaws is on a machine.

JWS is installed if Java 1.4.2+ is installed. It was with that version that it became co-bundled with the JRE. Between 1.2 (when it was introduced) and 1.4.2, it was available as a separate download.

To check that 1.4.2(+) is installed, use deployJava.js.
