Re: J2EE (Spring) + Flex + Tomcat 6.0.18 problem
Hi and thanks for all responses. It sounds like a timeout, rather than an empty response. Please remove all comments and any passwords from your server.xml and post it here. [code] Server port=8005 shutdown=SHUTDOWN Listener className=org.apache.catalina.core.AprLifecycleListener SSLEngine=on / Listener className=org.apache.catalina.core.JasperListener / Listener className=org.apache.catalina.mbeans.ServerLifecycleListener / Listener className=org.apache.catalina.mbeans.GlobalResourcesLifecycleListener / GlobalNamingResources Resource name=UserDatabase auth=Container type=org.apache.catalina.UserDatabase description=User database that can be updated and saved factory=org.apache.catalina.users.MemoryUserDatabaseFactory pathname=conf/tomcat-users.xml / /GlobalNamingResources Service name=Catalina Connector port=8080 protocol=HTTP/1.1 connectionTimeout=2 redirectPort=8443 / Connector port=8009 protocol=AJP/1.3 redirectPort=8443 / Engine name=Catalina defaultHost=localhost Realm className=org.apache.catalina.realm.UserDatabaseRealm resourceName=UserDatabase/ Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false /Host /Engine /Service /Server [/code] Well, it looks like timeout occured, because time of failing response was about 21 seconds. But why? 50Mb free isn't a meaningful number. More useful to know how much memory the JVM is currently using and what it's heap is configured to use. I used probe and it showed that memory was dropping from 40 megabytes till 5-10 and then it was going back to 40. If you think it's a bug in Tomcat, you could try using the latest release instead of an older one. I shall try. -- Regards, Kitikat -- View this message in context: http://old.nabble.com/J2EE-%28Spring%29-%2B-Flex-%2B-Tomcat-6.0.18-problem-tp28818290p28878122.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

look at catalina.bat -X attributes (stack,minHeap and maxHeap) catalina will use parameters from JAVA_OPTS environment variable also..you could be experiencing some issues with permgen not being collected http://wiki.apache.org/tomcat/FAQ/Memory Martin Gainty __ Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité Diese Nachricht ist vertraulich.

if your bean implemenents implements Lifecycle it is likely that you LifecycleBean is not running in which case you'll need to restart it e.g bean id=lifecycle class=test.beans.LifecycleBean init-method=declaredInitMethod property name=initMethodDeclaredvaluetrue/value/property /bean if(!context.getBean(lifecycle).isRunning()) context.getBean(lifecycle).start(); if your bean implelements FactoryBeanEhcache then increase the timeToLive(default is 120sec) or maxElementsInMemory(default is 1) or maxElementsOnDisk(default is 1000) post your code if you need further assistance Martin Gainty __ Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité Diese Nachricht ist vertraulich.
