I've built an example web app using maven that is dying during
initialization and I can't figure out how to address the error.
I'm using jetty 7.4.2 and Shiro 1.1.0. My example app is using jetty
embedded.
My project compiles but when I try to run it, I get some errors:

# Quick Tip: Instead of having this configuration here in
web.xml, you can instead
# move all of this to a 'shiro.ini' file at the root of the
classpath and remove
# the 'config' init-param. Or you can specify the
'configPath' init-param and specify the
# path to a resource at any location (url, file or
classpath). This may be desired if the
# config gets long and you want to keep web.xml clean.

# The /login is not restricted to authenticated users

# login submissions. It is 'smart' enough to allow those

Lastly, here is my main java file "AppServer.java":

import org.eclipse.jetty.server.ssl.SslSelectChannelConnector;
import org.eclipse.jetty.webapp.WebAppContext;
public class AppServer
{
public static void main(String[] args) throws Exception
{
Server server = new Server();
SelectChannelConnector connector0 = new SelectChannelConnector();
connector0.setPort(80);
connector0.setMaxIdleTime(30000);
connector0.setRequestHeaderSize(8192);
SslSelectChannelConnector ssl_connector = new SslSelectChannelConnector();
String jetty_home =
System.getProperty("jetty.home","C:/jetty-hightide-7.4.2.v20110526");
System.setProperty("jetty.home",jetty_home);
ssl_connector.setPort(443);
SslContextFactory cf = ssl_connector.getSslContextFactory();
cf.setKeyStore(jetty_home + "/etc/keystore");
cf.setKeyStorePassword("OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4");
cf.setKeyManagerPassword("OBF:1u2u1wml1z7s1z7a1wnl1u2g");
server.setConnectors(new Connector[]{ connector0, ssl_connector });
WebAppContext context = new WebAppContext();
context.setDescriptor("/WEB-INF/web.xml");
context.setResourceBase("../JettyMavenHelloWarApp/src/main/webapp");
context.setContextPath("/");
context.setParentLoaderPriority(true);
context.setInitParameter("cacheControl","max-age=0,public");
ResourceHandler resource_handler = new ResourceHandler();
resource_handler.setDirectoriesListed(true);
resource_handler.setWelcomeFiles(new String[]{ "index.html" });
resource_handler.setResourceBase(".");
resource_handler.setCacheControl("max-age=0,public");
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[] { context, resource_handler, new
DefaultHandler()});
server.setHandler(handlers);
server.start();
server.join();
}
}
I've tried just about everything I can think of to fix this issue, but
nothing has worked so far.
