Response Time in Jasper Logs
We added the %D parameter to the AccessLogValve tag in our server.xml file and now all entries in the jasper logs contain a field showing the response time in milliseconds. That's very cool. I just want to be sure of one thing. Does the value represent the total time from the moment tomcat saw the client's request to the time it successfully delivered the full response? The reason I ask is that we have some users who are complaining that certain requests are taking a long time (up to a minute). Yet when we check the jasper logs, we see that 97% of all requests are satisfied in < 50ms, and there are no requests that take longer than 20 seconds. So I'm trying to reconcile what I'm hearing from users with what I'm seeing in the logs.

Re: Http Session Null issue

Re: Http Session Null issue
Keep it simple. Try this first, if your problem is the "missing" attribute from http session. At least this what i would do in your place: > Maybe, you're getting a new session every time you're calling > this page > and "settings" reference is getting null.

Do you have the same session id before calling each one ? After that you could try to imagine more complex scenarios (more unlikely to happen) like: Are you Tomcat running behind a web server with load balance ? Is the web server proxying http requests correctly or it is sending each request to a different Tomcat instance/pair ? Are you accessing Tomcat hostname directly or throw a "logical"/mapped hostname resolved to distinct places/IPs ?

Re: Http Session Null issue
Hi Daniel, Yes, at Weblogic, request.getSession() is returning a non-null value AND "(Settings) session.getAttribute(ATTR_NAME)" is > working. On Tomcat out of 5 requests this is happening for 2 times. Let me explain the deployment architecture: 1. User invokes JSP page 2. JSP calls homegrown framework which performs operation and generates XML response 2.1 This XML framework also works on sessions and request objects. 3. XSLT transforms XML into HTML and displays on UI It looks like JSP and Servlets are using different sessions ??? Any pointers would be useful. Regards, Achal.

Why do you think there should be more connections? The connection pool size of mod_jk is the maximum. If no more than 2 to 4 are needed there will be no more connections.

Re: JSP when tag question
Following up on what Pid suggested, when you look at the output (view
source in the browser), can you see the and tags
still present? Can you offer us a little more info like what you have
declared for taglibs at the top of this jsp and what's in your webapp's
WEB-INF/lib folder?

Re: Http Session Null issue
How can the session been null if you're calling request.getSession() ? "(...) Returns the current session associated with this request, or if the request does not have a session, creates one. (...)" http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/http/HttpServletRequest.html#getSession() Maybe, you're getting a new session every time you're calling this page and "settings" reference is getting null. I *think* this can happen if: - Something is invalidating the session before request.getSession get called; - Your http client don't support cookies or is not sending the same cookie every time; - URL rewriting is disabled. Look the value returned by request.getRequestedSessionId() or session.getId(). If the same user call this page a lot of times, the same id should be returned. The best approach is look this value (session id) right before session.setAttribute(ATTR_NAME, settings) and session.getAttribute(ATTR_NAME) have been called.

It's probably trying to sync the session with other nodes, and this object is stored in the session. The rest of the stack trace would probably indicate that the cluster is trying to replicate sessions (or just this object, as it is being inserted into the session) or something like that. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEUEARECAAYFAkpOGjoACgkQ9CaO5/Lv0PAKfgCVGPJmrP+xs5Aypo60NEU8uk2y TwCfTuaeseQX6b4g3qJNFCU85oezZGU= =iNCj -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

When run, the lines inside the 'when' construct print the

32 INFO EL is page2
The test expression of line 19 is evaluated again at
line 20 and the result is 'false' as shown at line 31.
The output produced by line 22 is shown at
line 32 and confirms that the value of midContent is 'page2'.
Can someone explain why the code inside
the '' tag is executed when
the test on line 19 appears to be evaluating to false?
Is the c:choose actually being executed? Check the HTML source.
What else is in the "choose" block? No duplication?

The problem is that connection_pool_size is set to 60 and httpd available threads per chilf is set to 60 and tomcat max threads set to 100 and min set to 60 and checking netsat tells that there are only 2 to 4 connections between httpd.worker and tomcat AJP port. It can be caused by many things, and the probable one is the configuration. And BTW, your stup won't work well. If the connection_pool_size is 60 you will have 60 * MaxClients/ThreadsPerChild connections to Tomcat, and given your 100 limit this will not work. The proper number is: connection_pool_size = maxThreads in Tomcat / (MaxClients / ThreadsPerChild) If you have in httpd.conf MaxClients 600 ThreadsPerChild 60 and maxThreads="100" for AJP Connector in server.xml this would give worker.xxx.connection_pool_size=10 (100/(600/60)) Regards -- ^(TM) - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
