More Information
If you've installed the J2SE documentation, then there's a lot of JWS information available locally in <JAVA_HOME>/docs/guide/jws/index.html, including the developers guide. In J2SE 5.0, several JWS examples are in the distribution (in the sample/ directory). In earlier JWS versions, the code was scattered throughout the developers guide. The JWS home page at Sun (http://java.sun.com/products/javawebstart/) contains links to an official FAQ, technical articles, and installer demos.
In J2SE/JRE 1.4.2. or earlier, the JWS materials didn't contain the developers pack, which includes the complete JWS specification, JNLP API documentation, jardiff tool, and additional libraries. These have been folded into the main JWS release since 5.0. The pack is also available from http://java.sun.com/products/javawebstart/download-jnlp.html. The JWSt and JNLP developers forum is an active place (http://forum.java.sun.com/forum.jsp?forum=38).
The best unofficial JWS site is http://lopica.sourceforge.net/ with a lengthy FAQs page, useful reference sections, and links. However, it hasn't been updated in some time, and a lot of the FAQs page is about earlier versions of JWS.
The installer examples from Sun are at http://java.sun.com/products/javawebstart/demos.html. Another great source is Up2Go.Net (http://www.up2go.net), with installer categories including multimedia, communications, and over 40 games. Many of the games at the Java Games Factory can be downloaded using JWS, so their ...
