Motivation: - example/pom.xml has quite a bit of duplication. - We expect that we depend on npn-boot in more than one module in the near future. (e.g. handler, codec-http, and codec-http2) Modification: - Deduplicate the profiles in example/pom.xml - Move the build configuration related with npn-boot to the parent pom. - Add run-example.sh that helps a user launch an example easily Result: - Cleaner build files - Easier to add a new example - Easier to launch an example - Easier to run the tests that relies on npn-boot in the future

/**
|
|
* A SPDY Server that responds to a GET request with a Hello World.
|
|
* <p>
|
|
* This class must be run with the JVM parameter: {@code java -Xbootclasspath/p:<path_to_npn_boot_jar> ...}.
|
|
* The "path_to_npn_boot_jar" is the path on the file system for the NPN Boot Jar file which can be downloaded from
|
|
* Maven at coordinates org.mortbay.jetty.npn:npn-boot. Different versions applies to different OpenJDK versions.
|
|
* See <a href="http://www.eclipse.org/jetty/documentation/current/npn-chapter.html">Jetty docs</a> for more
|
|
* information.
|
|
* <p>
|
|
* You may also use maven to start the server from the command line:
|
|
* <pre>
|
|
* mvn exec:exec -Pspdy-server
|
|
* </pre>
|
|
* <p>
|
|
* Once started, you can test the server with your
|
|
* <a href="http://en.wikipedia.org/wiki/SPDY#Browser_support_and_usage">SPDY enabled web browser</a> by navigating
|
|
* to <a href="https://localhost:8443/">https://localhost:8443/</a>
