Hi all.My name is Nacho.I'm trying to install the dogtag certificate system on fedora 8. All packages have been installed perfectly but when I try to run the CA, the following error occurs: May 28, 2008 8:16:45 AM org.apache.catalina.core.ApplicationContext log SEVERE: Servlet castart threw unload() exception javax.servlet.ServletException: Servlet.destroy() for servlet castart threw exception at org.apache.catalina.core.StandardWrapper.unload(StandardWrapper.java:1373) at org.apache.catalina.core.StandardWrapper.stop(StandardWrapper.java:1688) at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4350) at org.apache.catalina.core.ContainerBase.removeChild(ContainerBase.java:893) at org.apache.catalina.startup.HostConfig.undeployApps(HostConfig.java:1191) at org.apache.catalina.startup.HostConfig.stop(HostConfig.java:1162) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:313) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:120) at org.apache.catalina.core.ContainerBase.stop(ContainerBase.java:1055) at org.apache.catalina.core.ContainerBase.stop(ContainerBase.java:1067) at org.apache.catalina.core.StandardEngine.stop(StandardEngine.java:448) at org.apache.catalina.core.StandardService.stop(StandardService.java:510) at org.apache.catalina.core.StandardServer.stop(StandardServer.java:734) at org.apache.catalina.startup.Catalina.stop(Catalina.java:602) at org.apache.catalina.startup.Catalina.start(Catalina.java:577) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:623) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:295) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:433) I took this error from the file "catalina.out" of the CA because the browser was closed instantly Does anyone have any idea how to fix it? Thank you very much!
