So I put the contents of my pom.xml file and my web.xml and my application
in this posting. You just gotta scroll down (a lot).
One thing I didn't post was the command I'm using to compile and run my app
which is the following:
mvn clean compile exec:java

Subject: Re: Runtime error in web app
Can you share your pom, the command you use to run, and any shiro
integration code? My first guess would be that you need slf4j libs on
your classpath.
Thanks,
Jared

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:

'configPath' init-param and specify the

classpath). This may be desired if the
# config gets long and you want to keep web.xml clean.

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

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.
