Hi Josh, This stack suggests that Jetty is trying to create the Guice PersistFilter, which will fail because it's expecting to be created and injected by Guice (PersistFilter has no default constructor). You need to use the latest Guice servlet extension: http://code.google.com/p/google-guice/wiki/Servlets which will automatically inject any filters and servlets that need injection (as long as you setup the top-level filter and add a servlet context listener to create the injector). -- Cheers, Stuart > java.lang. > InstantiationException: com.google.inject.persist.PersistFilter > at java.lang.Class.newInstance0(Class.java:340) > at java.lang.Class.newInstance(Class.java:308) > at org.mortbay.jetty.servlet.Holder.newInstance(Holder.java:153) > at org.mortbay.jetty.servlet.FilterHolder.doStart(FilterHolder.java:92) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) > at > org.mortbay.jetty.servlet.ServletHandler.initialize(ServletHandler.java:662) > at org.mortbay.jetty.servlet.Context.startContext(Context.java:140) > at > org.mortbay.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1272) > at > org.mortbay.jetty.handler.ContextHandler.doStart(ContextHandler.java:517) > at > org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java:489) > at > org.mortbay.jetty.plugin.Jetty6PluginWebAppContext.doStart(Jetty6PluginWebAppContext.java:115) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) > at > org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) > at > org.mortbay.jetty.handler.ContextHandlerCollection.doStart(ContextHandlerCollection.java:156) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) > at > org.mortbay.jetty.handler.HandlerCollection.doStart(HandlerCollection.java:152) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) > at > org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:130) > at org.mortbay.jetty.Server.doStart(Server.java:224) > at > org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) > at > org.mortbay.jetty.plugin.Jetty6PluginServer.start(Jetty6PluginServer.java:132) > at > org.mortbay.jetty.plugin.AbstractJettyMojo.startJetty(AbstractJettyMojo.java:441) > at > org.mortbay.jetty.plugin.AbstractJettyMojo.execute(AbstractJettyMojo.java:383) > at > org.mortbay.jetty.plugin.AbstractJettyRunMojo.execute(AbstractJettyRunMojo.java:210) > at > org.mortbay.jetty.plugin.Jetty6RunMojo.execute(Jetty6RunMojo.java:184) > at > org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:490) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:694) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeStandaloneGoal(DefaultLifecycleExecutor.java:569) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:539) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:387) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:348) > at > org.apache.maven.lifecycle.DefaultLifecycleExecutor.execute(DefaultLifecycleExecutor.java:180) > at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:328) > at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:138) > at org.apache.maven.cli.MavenCli.main(MavenCli.java:362) > at > org.apache.maven.cli.compat.CompatibleMain.main(CompatibleMain.java:60) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:597) > at org.codehaus.classworlds.Launcher.launchEnhanced(Launcher.java:315) > at org.codehaus.classworlds.Launcher.launch(Launcher.java:255) > at > org.codehaus.classworlds.Launcher.mainWithExitCode(Launcher.java:430) > at org.codehaus.classworlds.Launcher.main(Launcher.java:375) > > Web.xml > <?xml version="1.0" encoding="ISO-8859-1"?> > <web-app xmlns="http://java.sun.com/xml/ns/j2ee";
