That's the standard version that we have inside our environment for Prod move at this point. Tomcat 7.0.8 build is underway but not in our Prod environment yet. So, for now I have to use the current standard version and hence using this particular version 6.0.18. The same jsp:include code works fine in JRUN server but in Tomcat for the page to work properly I have to clear the cache under work/catalina before accessing the page every time.

I understand that there is a way to prevent this caching under work/catalina but trying to figure out if there is a way where I can explicitly tell Tomcat to recompile this particular jsp file upon each request. I looked at JRUN to see if it was caching that particular JSP page and even it does it as well. Issue details: We are having a list that populates the data from database. For example: page number field with values 0,1,2,3,4 Ok so far. On first time, it does show the proper page selected value - say 4. Not enough information to understand what this means. Can you post code or explain in more detail please? Sorry, about that. Here is the detailed explanation. html:options collection=pages property=pageNumber styleClass=textbody/ So, during first time access - html view source option value=0 class=textbody0/option option value=1 selected=selected class=textbody1/option option value=2 class=textbody2/option option value=3 class=textbody3/option option value=4 class=textbody4/option option value=5 class=textbody5/option If you notice there is a selected on option value=1 and default option on page load will be selected to option value 1 The next time when we try to access it the selected value does not show up correctly and it just defaults the first record in the drop down - 0. I did view source of the html and see the select tag not present upon future requests. So the entire SELECT form element is missing? The selected selected is missing upon future requests. This is how it will be and since selected is not there it would default to first record 0. option value=0 class=textbody0/option option value=1 class=textbody1/option option value=2 class=textbody2/option option value=3 class=textbody3/option option value=4 class=textbody4/option option value=5 class=textbody5/option When I empty the content in nwork/catalina (no tomcat restart) then it recompiles the file and would show up the proper value. Still pretty vague as to what you are doing... I cannot get it show proper selected value on screen until I go to work\Catalina\localhost\ and delete the previous xyz_jsp.java compiled version. I go here and delete this cached file. Then access the same screen again This time it would show up like before. Selected option on option value =1 and will default correctly. Please let me know if you need further inputs or if am still unclear in trying to explain the whole problem. p The same code works fine in JRUN and am trying to figure out how to get this working in Tomcat without having to clear Tomcat cache.

RE: Tomcat 6.0.18 Caching Question
I very well understand the point everyone are trying to make here . But, unfortunately I have to go with the approved version with in our environment. I believe there were also talks about 7.0.26 but it will be quite some time before they pilot everything and approve the version for Prod usage :(. I don't have any authority to change how things work but will for sure bring that concern up to the architect team when I meet with them next time.

RE: Tomcat 6.0.18 Caching Question
All evidence at the moment indicates that your JSP code is the most likely suspect. Okay, I will scan through the logic in the code once again very closely. Like I said before the same code works fine in JRUN and also in Tomcat for the first time. This problem occurs only in Tomcat upon subsequent access. If I get rid of the jsp_java then in work/catalina then it would start working again properly. So, I was under the impression that some kind of a cache problem. And again, at least trying it on a current version would either confirm or eliminate the possibility that the problem has been fixed sometime in the past four years (if it is a Tomcat problem). Sure, I will try to download the latest version and give it a shot to see if the problem manifests in there. Sorry, did not interpret from your original response that you want me to try in latest Tomcat version. I have no problems in doing so and am not against it. It is just that I was trying to explain the reasons for this particular version usage. PS: Hoping that I am not asking any questions on a version that is EOL. Lastly, I am not trying to be irresponsible or willing to post ill-described questions:( Just thought of getting some experts advise here and no other intentions:) THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Question on Performance Tuning
Currently we are running Java 1.5 with 64 bit version on the superdome server with Redhat O/S. But we have not specified the -server option in the JAVA_OPTS. Is it must to have -server option specified when you are using a 64 bit Java. The CPU utilization nags me very much. The performance of the application pages/transactions are meeting our targets except the cpu target. We have the same application running on Weblogic/Apache/Oracle on Solaris O/S in which the CPU for 100 virtual user is 50-60%. To identify the surge in CPU, I tested the following scenario's yday. 2 users - Single Tomcat - 12-18% of CPU 4 users - Single Tomcat - 20-30% of CPU 6 users - Single Tomcat - 40-50% of CPU More than 6 users - Single/Double Tomcat - CPU utilization is 70-80%. Even if I test with 25/50/100 users the CPU maintains at 70%. We have max threads as 40 and I increased to 60 but did not find any difference in CPU. My application is an internet based one which currently has half a million page views everyday. In the near future it may exceed one million. I cannot test more than 100 users as we do not have license for more than 100 users. Is it a normal behavior of the tomcat ?

Re: Question on Performance Tuning
Thanks Chuck.. One question thou.. in the JAVA_OPTS do we have to specify -server cos it runs as client by default. Will it bring any change to performance ?

Thread dumps are appropriate for diagnosing hangs, but they're not terribly useful for analyzing CPU usage. You'd be better off running a profiler to see where time is being spent. Even the JVM's built-in hprof running in sample mode should give you a pretty good idea of where the cycles are going (or use JVisualVM). Can I get some pointers on anything to be tuned in the tomcat to reduce the cpu utilization. First, find out what's really using the CPU before fiddling with anything. Tweaking Tomcat is not likely to change much assuming the thread pool and heap are adequate for your load. You've specified several GC options that may or may not be appropriate. Unless you've proven that changing NewRatio, NewSize, MaxNewSize, and SurvivorRatio actually helps your throughput, you're likely better off leaving them alone. 128M MaxPermSize may be too small if you have a lot of classes in your webapps. Enabling concurrent GC produces more regular response times, but will actually *reduce* throughput in most cases. These might help slightly: * Remove AspectJ. * Turn off PrintGCDetails. * Remove unused webapps. * Precompile JSPs. * Turn off auto-deployment. * Turn off monitored resources. * Set the parameters for the JSP servlet (in conf/web.xml) for production. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Issue in connecting to tomcat via Apache
Hi Larry, Thanks for the headsup. Well I tried using the commented line earlier but it failed. So I tried again by commenting out the JMount parameter. I was trying to access the URL : http://localhost/examples with a JKMount details as follows.. JkMount /examples/* worker1. It did not redirect the request from httpd to the tomcat. So I commented the line JkMount and tried accessing the url, it still failed...

Re: Issue in connecting to tomcat via Apache
Martin, I m trying to access the folder /examples on the localhost which is actualy hosted in the TOMCAT. http://localhost/examples . The tomcat is running on port 8080 and the httpd is running on 8000. When I access the same folder using the port like http://localhost:8080/examples is successful. I tried the two options on worker properties like JkMount /examples/* worker1 JkMount / worker1 But both of them did not fwd the request to tomcat via the httpd. There are no pointers in the log files of jk/httpd/tomcat etc.. Thanks. Thanks.

Re: Issue in connecting to tomcat via Apache
All, A brief on wat i did. 1. Downloaded the httpd 2.2.8 and tomcat 6.0.16 versions. 2. Httpd installation ./configure --with-included-apr --prefix=install directory Listening on port 8000 3. Tomcat installation Modified the catalina.sh file to point to the tomcat home/jdk home STarted and listening on 8080 4.mod_jk installation Tried the build and install method using the source code file. Also the binary file downloaded from the apache site was copied to /modules dir of the httpd. jk logs doesnot show any error , while starting the httpd process. As wel the httpd and tomcat doesnt show any errors.

IIS JK connector problem
Hi, We are trying to migrate a running tomcat/JK/IIS setup from win 2000/IIS 5.0 to win 2003/IIS 6.0. The struts application is hosted using two tomcat instances and we use JK connectors as load balancer for these two servers. We have configured the IIS with a 'jakarta' virtual directory.The setup is working fine in 2000/IIS 5.0 setup but not in the 2003/IIS 6.0. We have copied the ISAPI_REDIRECT.DLL frile from the 2000 box to 2003 box (we did not use any binary installation) and in the IIS the status for the jakarta shows as loaded with a green uparrow. But when we try to browse the site we get '404- File or directory not found error'. I've listed the config files below 1.isapi_redirect.properties # Configuration file for the Jakarta ISAPI Redirector # The path to the ISAPI Redirector Extension, relative to the website # This must be in a virtual directory with execute privileges extension_uri=/jakarta/isapi_redirect.dll # Full path to the log file for the ISAPI Redirector log_file=F:\tomcat\JakartaIsapiRedirector_PF\log\isapi_redirect.log # Log level (debug, info, warn, error or trace) log_level=info # Full path to the workers.properties file worker_file=F:\tomcat\JakartaIsapiRedirector_PF\conf\workers.properties.minimal # Full path to the uriworkermap.properties file worker_mount_file=F:\tomcat\JakartaIsapiRedirector_PF\conf\uriworkermap.properties 2.uriworkermap.properties # uriworkermap.properties - IIS # # This file provides sample mappings for example ajp13w # worker defined in workermap.properties.minimal # The general sytax for this file is: # [URL]=[Worker name] /*=loadbalancer # Optionally filter out all .jpeg files inside that context # For no mapping the url has to start with exclamation (!) ##!/servlet-examples/*.jpeg=loadbalancer 3.workers.properties.minimal ps=/ worker.list=loadbalancer worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers=ajp13wpf, ajp13wpf2 worker.ajp13wpf.port=8019 worker.ajp13wpf.host=localhost worker.ajp13wpf.type=ajp13 worker.ajp13wpf.lbfactor=1 worker.ajp13wpf2.port=8029 worker.ajp13wpf2.host=localhost worker.ajp13wpf2.type=ajp13 worker.ajp13wpf2.lbfactor=1 # Disable worker2 for all requests except failover #worker.worker2.disabled=True 4.server.xml(instance-1)-- Server port=8015 shutdown=SHUTDOWN 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=8090 maxThreads=550 minSpareThreads=50 maxSpareThreads=100 enableLookups=false acceptCount=50 connectionTimeout=2 disableUploadTimeout=true / Connector port=8019 enableLookups=false protocol=AJP/1.3 / Engine name=Catalina defaultHost=appname.domain.net jvmRoute=ajp13wpf !-- Valve className=org.apache.catalina.valves.RequestDumperValve/-- !--Logger className=org.apache.catalina.logger.FileLogger /-- Realm className=org.apache.catalina.realm.UserDatabaseRealm resourceName=UserDatabase/ Host name=appname.domain.net appBase=F:/tomcat/deploy/hosts/ins1/ unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Valve className=org.apache.catalina.valves.AccessLogValve directory=logs prefix=appname.domain.net_access_log. suffix=.txt pattern=common resolveHosts=false/ !--Valve className= org.apache.catalina.valves.ByteBufferAccessLogValve directory=logs prefix=appname.domain.net_access_log . suffix=.txt pattern=common resolveHosts=false/ -- /Host Cluster className=org.apache.catalina.cluster.tcp.SimpleTcpCluster managerClassName= org.apache.catalina.cluster.session.DeltaManager expireSessionsOnShutdown=false useDirtyFlag=true notifyListenersOnReplication=true Membership className=org.apache.catalina.cluster.mcast.McastService mcastAddr= 228.0.0.4 mcastPort=45564 mcastFrequency=500 mcastDropTime=3000/ Receiver className=org.apache.catalina.cluster .tcp.ReplicationListener tcpListenAddress=auto tcpListenPort=4011 tcpSelectorTimeout=100 tcpThreadCount=6/ Sender className= org.apache.catalina.cluster.tcp.ReplicationTransmitter replicationMode=pooled ackTimeout=15000/ Valve className= org.apache.catalina.cluster.tcp.ReplicationValve filter=.*\.gif;.*\.js;.*\.jpg;;.*\.txt;/ /Cluster /Engine /Service /Server The server.xml for the other instance is

Restart Tomcat Virtual Host - HOWTO
Hi, I have used tomcat to host a couple of my web sites, which are continuously evolving. I have configured them both as virtual hosts in tomcat and I am able to access them independently without any problem. The problem is... when I am updating some class files, jars in one of the websites, I would require to restart the virtual host for the changes to take effect. But this will cause my other website also to go down. I was wondering if there is a way to restart just one virtual host of a tomcat instance rather than the whole tomcat without effecting the other virtual hosts on that tomcat. I have searched through tomcat documentation, and also google, but there is no mention about this. I would appreciate if somebody could point me to a resource, giving info on this problem. Note: Individually reloading a web application is not a possible solution, because of memory-related issues. I am looking at clean restart of a tomcat virtual host. regards, Vasanth - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
