http://issues.apache.org/bugzilla/show_bug.cgi?id=37498 Summary: NPE in org.apache.catalina.core.ContainerBase.removeChild Product: Tomcat 5 Version: 5.5.12 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I moved the directory containing my web-app from the webapps / deployment area, I renamed it outside of the webapps/ tree. I was expecting it to viciously undeploy the application so I could then rename it back to cause a deploy. The application is setup with a context "" for the default context. The deployed folder name is "../webapps/ROOT" I think this is reproducable. At the time I moved the web-app folder I got multiple Exceptions, like the following: 14-Nov-2005 16:56:56 org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [] DEBUG 16:56:56,039 (ApplicationLifecycleListener.java:contextDestroyed:70) -contextDestroyed on "mywebapp" 14-Nov-2005 16:56:56 org.apache.catalina.loader.WebappClassLoader openJARs WARNING: Failed to open JAR java.util.zip.ZipException: No such file or directory at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.<init>(ZipFile.java:203) at java.util.jar.JarFile.<init>(JarFile.java:132) at java.util.jar.JarFile.<init>(JarFile.java:97) at org.apache.catalina.loader.WebappClassLoader.openJARs(WebappClassLoader.java:1561) at org.apache.catalina.loader.WebappClassLoader.findResourceInternal(WebappClassLoader.java:1792) at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:1587) at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:856) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1305) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1187) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at com.imin1way.project.task.ApplicationLifecycleListener.contextDestroyed(ApplicationLifecycleListener.java:72) at org.apache.catalina.core.StandardContext.listenerStop(StandardContext.java:3733) at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4306) at org.apache.catalina.core.ContainerBase.removeChild(ContainerBase.java:892) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1019) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1178) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:292) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1304) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1568) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1577) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1557) at java.lang.Thread.run(Thread.java:595) I guess it was trying to open JAR files to load classes from the WEB-INF/lib to execute the ContextListener.destroyContext() and any unloaded classes is needed to run. However the background task is now stuck doing this every 10 seconds: 14-Nov-2005 16:58:36 org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [] 14-Nov-2005 16:58:36 org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor processChildren SEVERE: Exception invoking periodic operation: java.lang.NullPointerException at org.apache.catalina.core.ContainerBase.removeChild(ContainerBase.java:883) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1019) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1178) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:292) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1304) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1568) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1577) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1557) at java.lang.Thread.run(Thread.java:595) I would expect Tomcat to be able to reliabily recover from this sort of abuse :) Do bad things happen in TC when an exception is throw from the destroyContext() ? Let me know if you need more info or maybe even a test case if the cause / solution isn't clear enough. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
