Hi,
using Heroku archetype jetty 11,
It appeared the jetty configurations may be different
when running mvn jetty:run compared to running
embedded jetty using the main class. (below)
That is to say I would need to add further programmatic configuration to
the embedded jetty.
/**
* This class launches the web application in an embedded Jetty container.
* This is the entry point to your application. The Java
* command that is used for launching should fire this main method.
*/
public class Main {
public static void main(String[] args) throws Exception{
// The port that we should run on can be set into an environment
variable
// Look for that variable and default to 8080 if it isn't there.
String webPort = System.getenv("PORT");
if (webPort == null || webPort.isEmpty()) {
webPort = "8080";
}
final Server server = new Server(Integer.valueOf(webPort));
final WebAppContext root = new WebAppContext();
root.setContextPath("/");
// Parent loader priority is a class loader setting that Jetty
accepts.
// By default Jetty will behave like most web containers in that it
will
// allow your application to replace non-server libraries that are
part of the
// container. Setting parent loader priority to true changes this
behavior.
// Read more here:
http://wiki.eclipse.org/Jetty/Reference/Jetty_Classloading
root.setParentLoaderPriority(true);
final String webappDirLocation = "src/main/webapp/";
root.setDescriptor(webappDirLocation + "/WEB-INF/web.xml");
root.setResourceBase(webappDirLocation);
server.setHandler(root);
server.start();
server.join();
}
}
