I am trying to generate a jetty 9.4.8 embedded webapp with javalite activeweb that is a servletFilter based framework.
I develop a server main with a webappContextHandler, but i obtain always that exception:

My actual aproximation is using webappcontext, but i was trying with others kinds of handlers:
public static void main(String[] args) throws Exception {
server = new org.eclipse.jetty.server.Server(8000);
WebAppContext contextHandler = new WebAppContext();
contextHandler.setContextPath("/");
contextHandler.setWar("target/classes/WEB-INF");
FilterHolder filter = contextHandler.addFilter(org.javalite.activeweb.RequestDispatcher.class, "/", EnumSet.of(DispatcherType.REQUEST));
filter.setInitParameter("exclusions", "css,images,js,ico,woff,svg,png");
filter.setInitParameter("root_controller", "home");
//session
final DefaultSessionIdManager idmgr = new DefaultSessionIdManager(server);
idmgr.setServer(server);
server.setSessionIdManager(idmgr);
JDBCSessionDataStore sessionStore = new JDBCSessionDataStore();
DatabaseAdaptor databaseAdaptor = new DatabaseAdaptor();
databaseAdaptor.setDatasource(dataSource);
sessionStore.setDatabaseAdaptor(databaseAdaptor);
SessionHandler sessionHandler = new SessionHandler();
DefaultSessionCache cacheSession = new DefaultSessionCache(sessionHandler);
sessionHandler.setSessionCache(cacheSession);
cacheSession.setSessionDataStore(sessionStore);
sessionHandler.setSessionIdManager(idmgr);
contextHandler.setHandler(sessionHandler);
server.setHandler(contextHandler);
try {
server.start();
server.dumpStdErr();
server.join();
System.out.println("finalling main");
} catch (Exception t) {
t.printStackTrace();
} finally {
if (dataSource != null && !dataSource.isClosed()) {
dataSource.close();
}
if (server != null && server.isRunning()) {
server.setStopTimeout(10);
server.stop();
}
System.out.println("finalled");
}
}
Any ideas?

suggestions are welcome
edit 1:
actually i try:
ServletContextHandler contextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
contextHandler.setContextPath("/");
contextHandler.setHandler(sessionHandler);
ServletHandler servletHandler = new ServletHandler();
FilterHolder filter = servletHandler.addFilter("org.javalite.activeweb.RequestDispatcher", "/", EnumSet.of(DispatcherType.REQUEST));
filter.setInitParameter("exclusions", "css,images,js,ico,woff,svg,png");
filter.setInitParameter("root_controller", "home");
HandlerCollection collectionHandler = new HandlerCollection(servletHandler,contextHandler);
server.setHandler(collectionHandler);
exception disapear, but when call a webpage freemarker say that not find templates, because servletcontext is null
Finally I achieve.
i publish a example in:
https://github.com/devMls/base_embedded_jetty
for if can it help someone.
