Session is replicated without jsf beancontents in cluster
Hi, I set up a simple tomcat cluster using the example from http://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html but using the BackupManager. I deployed a simple jsf portlet/app where you can store values in an application scoped and a session scoped bean. I access one server through a loadbalancer (haproxy) configured for sticky sessions. When I store a value in the session bean I can see a session being created in the manager/html/sessions for my app on both servers. However if I shut down the current server and get directed to the other one by the LB the session value is gone although I still continue using the same JSESSIONID. Any ideas for resolving that? background info: - Tomcat: bundled with Liferay 6.1. Tomcat version is 7.0.27. - no SerializationException in the logs - tested on Ubuntu VMs in VirtualBox and on real Win7 boxes connected via router - time is synced (both consoles show same time) - no WARN or ERROR messages in the consoles - app works fine while on one server - distributable/ tag is set in Liferay and my app - tomcats notice when the other one dissappears - in Liferay forums I was told it was a tomcat issue - in the session there is an attribute (sessbean is my session bean, cloudapp is my app): * name: javax.portlet.p.cloudtest_WAR_cloudapp_LAYOUT_10639?sessbean * value: [package of the bean].MySessionScopeBean@5394f184 I'm a newbie to this, so it might be something trivial (also since it's a basic example). Thanks for any advice!

jdbc connection pool, hanging threads and same physical connection usage
Hi, We are experiencing some problems while using the tomcat jdbc pool. Tomcat version: apache-tomcat-7.0.29 Pool settings: Resource name=PilDevDS auth=Container type=javax.sql.DataSource factory=org.apache.tomcat.jdbc.pool.DataSourceFactory testWhileIdle=true testOnBorrow=true testOnReturn=false validationQuery=SELECT 1 FROM PIL_USERS validationInterval=3 timeBetweenEvictionRunsMillis=3 maxActive=100 minIdle=10 maxWait=1 initialSize=10 removeAbandonedTimeout=60 removeAbandoned=true logAbandoned=true minEvictableIdleTimeMillis=3 jmxEnabled=true jdbcInterceptors=org.apache.tomcat.jdbc.pool.interceptor.ConnectionStat e;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer username=PCS password=xxx driverClassName=oracle.jdbc.driver.OracleDriver url=jdbc:oracle:thin:@somehost / Under heavy load we regularly see a thread waiting for response on a socketRead. Furthermore we see one or more threads trying to lock the same physical connection as used by the 'hanging thread'. See threaddump excerpt further on for an example. Questions: - How is it possible that a thread tries to get a lock on a physical connection which is part of a pooled connection which is not idle? - The 'poolcleaner' also hangs as it is trying to clean the 'hanging connection'. This would mean that one hanging thread will bring the pool to its knees?

Yes.
If foo is a system property, you can use ${foo} in any XML file
parsed by Tomcat.

NPE in coyote InternalNioOutputBuffer
Hello
I have the commet application - some sort of event bus where requests are
turned in async mode then stored in internal cache and when event occures
/ or request times out response is sent back to subscriber (it is handled
with my executor worker threads).
It worked fine until I have added a line with calling flushBuffer on
response object. My goal was to mark the connection as commited - I am
checking whether I have already written to this response
(response.isCommited()) in some other part of my code.
Now errors like these pop out in my logs

Maybe I'm missing something here, but I never seen how ThreadLocal does real harm, neither I can imagine it, please enlighten me ;-) Abusing ThreadLocal (which is what's going on here) can have very serious side effects, depending on what's stored via the reference. For example, if something specific to the request or session is kept in the ThreadLocal and not refreshed on the next unrelated request, inadvertent data sharing and potential corruption can occur. During one of the Tomcat get-togethers, we had discussed associating ThreadLocal instances with sessions rather than Threads, but that would have been a good bit of work. We settled on just purging such threads from the pool. Libraries written for non-thread-pool environments should be documented as such, and used only with great caution in server environments. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Hi, When we run an IIS application in a different Application Pool rather than the site's default Application Pool , we are getting 403.18 : The Specific Request Cannot Be Executed from Current Application Pool.

Re: Tomcat Unix daemon (jsvc) - problem with compilation
2013/5/26 Jaroslav Fikker fik...@atlas.cz: Hello. To Chris: Thank you very much for your comments. Is there anyone who knows why Tomcat 7.0.25 (commons-daemon-1.0.8-native-src) started to use jni_md.h which is not part of IBM Java? I didn't encounter any problem with compilation of Tomcat Unix daemon (jsvc) until version Tomcat 7.0.23 (commons-daemon-1.0.7-native-src). Is it bug or intention? Thank you very much for your help. The daemon is a subproject of Apache Commons, not of Tomcat, http://commons.apache.org/proper/commons-daemon/ http://svn.apache.org/viewvc?diff_format=lview=revisionrevision=1194902 I would guess that you cannot compile JNI code with Oracle Java, unless you have the directory containing jni_md.h (machine-dependent part of jni.h) on your include path. The file is not in JDK/include/ directory, but in JDK/include/os/ where os name varies. -classpath /opt/tomcat/lib/tomcat-api. jar,/opt/tomcat/lib/tomcat-api.jar,/opt/tomcat/lib/tomcat-util.jar,.. Why?? You are trying to place those libraries into System classloader. The recommended configuration is to put only several jars there. The Tomcat's Bootstrap class will configure the Common classloader as appropriate. It is documented here: http://tomcat.apache.org/tomcat-7.0-doc/class-loader-howto.html 6.

HttpServletRequest and HttpServletResponse objects
a) are not thread-safe
b) are cached and reused for subsequent incoming requests.
so what are you doing to ensure that you do not access it concurrently
and beyond its life cycle?
I would recommend to configure the following system property in the
catalina.properties file:
org.apache.catalina.connector.RECYCLE_FACADES=true
It will prevent reuse of those objects.
