Hey gus, I'm trying to configure the tomcat server using the memchached, I used this tutorial :
http://code.google.com/p/memcached-session-manager/wiki/SetupAndConfiguration But when starting the tomcat I have this error and cannot access any application on tomcat : 18/Nov/2009 17:39:18 de.javakaffee.web.msm.MemcachedBackupSessionManager init INFO: MemcachedBackupSessionManager starts initialization... 18/Nov/2009 17:39:18 de.javakaffee.web.msm.SessionTrackerValve <init> INFO: Setting ignorePattern to .*\.(png|gif|jpg|css|js)$ 2009-11-18 17:39:19.044 INFO net.spy.memcached.MemcachedConnection: Added {QA sa=/xxx.xxx.xxx.xxx:11211, #Rops=0, #Wops=0, #iq=0, topRop=null, topWop=null, toWrite=0, interested=0} to connect queue 2009-11-18 17:39:19.049 INFO net.spy.memcached.MemcachedConnection: Added {QA sa=/xxx.xxx.xxx.xxx:11212, #Rops=0, #Wops=0, #iq=0, topRop=null, topWop=null, toWrite=0, interested=0} to connect queue 2009-11-18 17:39:19.062 INFO net.spy.memcached.MemcachedConnection: Connection state changed for sun.nio.ch.selectionkeyi...@1a9d1b 2009-11-18 17:39:19.062 INFO net.spy.memcached.MemcachedConnection: Connection state changed for sun.nio.ch.selectionkeyi...@787c16 18/Nov/2009 17:39:19 org.apache.commons.modeler.Registry registerComponent SEVERE: Null component Catalina:type=JspMonitor,name=jsp,WebModule=// localhost/,J2EEApplication=none,J2EEServer=none java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:295) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:433) Caused by: java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.<init>(IF)V at de.javakaffee.web.msm.NodeAvailabilityCache.<init> (NodeAvailabilityCache.java:55) at de.javakaffee.web.msm.MemcachedBackupSessionManager.createNodeAvailabilityCache (MemcachedBackupSessionManager.java:278) at de.javakaffee.web.msm.MemcachedBackupSessionManager.init (MemcachedBackupSessionManager.java:272) at de.javakaffee.web.msm.MemcachedBackupSessionManager.start (MemcachedBackupSessionManager.java:860) at org.apache.catalina.core.StandardContext.start (StandardContext.java:4166) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java: 1014) at org.apache.catalina.core.StandardHost.start(StandardHost.java:736) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java: 1014) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java: 443) at org.apache.catalina.core.StandardService.start (StandardService.java:448) at org.apache.catalina.core.StandardServer.start(StandardServer.java: 700) at org.apache.catalina.startup.Catalina.start(Catalina.java:552) ... 6 more Any idea about this problem ?
