I started seeing error log entries to this effect once we ported a Tomcat webapp, which connects to a remote database, from Tomcat 5 to Tomcat 6.0.26, but it seemed relatively harmless until now. The error we got at first was:
Code:

clearReferencesStopTimerThread
SEVERE: A web application appears to have started a TimerThread named [Timer-7] via the java.util.Timer API but has failed to stop it. To prevent a memory leak,the timer (and hence the associated thread) has been forcibly cancelled. A restart seemed to cure the server at that point. But now it has died silently: though the process itself was running, the service become unavailable. Entries like this were found in the logs:
I was downloading some PHP and MySQL tools, and one of my downloads was not going anywhere. So, I restarted my computer, and now it gives me an error when I try and download it again (see below): Message: "The installation could have failed because of an error in the corresponding software package or it was cancelled in an unfriendly way. You have to repair this before you can install or remove any further software."
dmesg | grep -i time ACPI: PM-Timer IO Port: 0x408 Calibrating delay using timer specific routine.. 4658.19 BogoMIPS (lpj=2329098) Using local APIC timer interrupts.
I have Squeeze with 2.6.32 kernel, fresh installation and Intel 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device.I have done all updates, but Gnome Desktop freezes every day completely, I can move the mouse, but nothing happens.Keyboard works, but I can press only Ctrl-Atl-F1 and Ctrl-Alt-Del to reboot.
The "MP-BIOS bug: 8254 timer not connected to IO-APIC" error message shows up on boot on at least one of my RHEL servers, and I'm not quite sure what to make of it. My understanding of the situation is that the timer is located elsewhere on the motherboard than where the kernel looks for it. Is this correct?
I've come across people suggestin one should disable APIC by adding "noapic" to the kernel boot options, but which consequences does this imply - in SNP setups only one CPU will be used by the kernel?
Whenever vlc is running and I try to log out, a KDE window opens and tells me "logout cancelled by vlc". I have to repeat the process. How do I disable this unwanted "feature"? What if Thunderbird, Firefox, LibreOffice, Gwenview etc. all decided I shouldn't log out? Would I have to log out six or seven times? Doesn't sound logical to me.
Can anyone tell me in performance tunning of apache-tomcat and jboss application server?when I deploy some application in apache-tomcat the performance is say 100 users per second and incase of jboss it is even worst (35-40 users per second)i want to improve my performance 1000 uesrs per second..
I have a requirement of using a wildcard certificate for 5 subdomains running under apache httpd server and 1 subdomain under tomcat.Is there any possibility of using the single wildcard certificate both in tomcat and apache
I have one server with Jboss and Tomcat installed, I have to start these servers manually everytime I do reboot the server.How I could do to start Jboss and Tomcat automatically, when I do reboot the server?
i have a problem with one of my PCs which refuses to run the CCLc timer on its screen, i have tried to run the application so many times but every time i run it it does not connect to the server to show the timer automatically as the other PCs do,therefore the client cannot know how much he/she is supposed to pay.this forces us to manually time the clients that are using that PCs.
I've been scouring the internet and these forums for answers and have yet to figure anything out.Here's the situation: My boss's computer (HP running Vista) decided it didn't want to boot anymore. (Error: Cannot find Bootlog.xxx) My boss used a recovery disk to attemp a 'repair' but unintentionally began a format cancelling it at 1-3%. I created a LiveUSB that I can boot off of, and Ubuntu recognizes 52gb of Data on the drive. However when I go to view the drive nothing is there. I am assuming that the 'page file' was deleted although the rest of the information wasn't.
My question is: Is there anyway to access this data although the information telling the computer what is there and where it is has gone AWOL?I'm trying to get the payroll information off of the computer so she can finish her taxes, I will be working on this all night. If anyone wants to provide real time help my AIM screen name is 'Fryphax'.
I am stuck with an issue related to domain hosting. Currently i have an application hosted in my own server using a static ip from a service provider. I got a domain name from another domain provider. Everything went in right way till when i click my url in browser using internet through another system. I am able to see my application when i use my ip address, where as when i use my domain name its not working.
I have used same Hardware and OS platfrom for web server benchmarking and i have used similar php and jsp scripts for Apache and Tomcat. For this testing i have used apache ab benchmarking toolFrom this statistics i would like to clarify the performances about Apache and Tomcat.
1. why Tomcat have taken too much of time to finish this 10 million requests to compare with Apache? 2. why this huge different for "Request per Second"? 3. To Tomcat i have increased multi thread level 300 and JVM memory usage upto 2048mb(but performances not increased), rather than these, is there any other performance tune-up settings for Tomcat? 4. from these statistics, can i come to the conclusion that apache is the best? 5.do u feel that ab tool favouring to Apache?
I'm configuring a web server using Apache and Tomcat. I use Apache 2 and various instances of Tomcat5 and Tomcat6..I try that Apache serves the static data and tomcat the dynamic (Apache receives all requests, sending tomcat only the dynamic)I see that Apache and Tomcat can be connected using http or ajp Can any tell me: - What connector should I use: ajp, http,...? - How can I say Apache to serve the static data and Tomcat the dynamic?Due to I have many instances of Tomcat, connectins http and https, https with client certificates, and due to the port configuration: - Is there any way to configure Apache-tomcat without the use of ports in tomcat (a differect connector)?
we have configured snv in our server but when we tried to access our svn folder from client its saying path not found error.This is because apache is mapped to tomcat so when we tried to access svn by default it looks to some other path and displaying path not found error.My question is how to restrict apache from forwarding its request to tomcat or else how to stop the tomcat service. I am using centos and i tried with /etc/init.d/tomcat5 stop but it is not getting stopped.
I have application (WAR format) deployed on tomcat 5.5. I am able to access application using: "http://my_server_hostname/application_base_directory_name/hello.do" for example. I do not want my users to remember or bookmark the full link "http://my_server_hostname/application_base_name/hello.do"). Is there a way that i could have tomcat host it like a website and i can directly get the index page open by simply typing a url (http://hostname) in the browser? if possible, i would like to do it using tomcat only (no httpd connectors or modules).
I am trying to setup Tomcat on CentOS 5.2,This is that ive done so far...Installed Apache, which works fine and I get the "Apache 2 Test Page powered by CentOS" Did this
I should have caught this during the upgrade, I saw the potential problem but failed to write it down. All my applications served by Tomcat fail to load. Catalina logs show the following error for each app. Error deploying configuration descriptor msgboard.xml The complete error for an individual application is
[Code]...
Again, during the upgrade a warning popped up that each app would need to be spelled out in some configuration file SOMEWHERE because of a change in security! Would someone be so kind as to direct me as to where and how this would be accomplished. I apologizes for not being able to find this out on my own but have looked and can't find it. I'm pretty sure anyone proficient with Tomcat on Linux will know what and where these changes need to be made. Or if anyone knows if and where there is a log of all communication during the upgrade I might be able to figure this out on my own. Is there such a log kept during an upgrade? Also if this question would be more appropriate in the Server Platforms forum I will do that.
how I can deploy a WAR file with a Tomcat that happens to be installed on a server. I divided it to different small questions but no strait answer so far.
These are the things I've done:
created a myapps folder inside the tomcat directory, and copied the WAR file there.
These are the questions:
1. I did not touch anything inside the Tomcat folder, anything need to be changed?.
2.How to start the Tomcat so that it can deploy th e WAR file?
I am trying to start remote tomcat server, it's not working as expected. I like to mansion that..I am able to stop tomcat server remotly. Below command i am using
ssh -t remoteserver sudo sh /opt/tomcat/6.0.29/apache-tomcat/bin/catalina.sh start ssh -t remoteserver sudo sh /opt/tomcat/6.0.29/apache-tomcat/bin/startup.sh
Both are not working..when i run this script locally it's working file
same way when i run tomcat stop command it's working fine. ssh -t remoteserver sudo sh /opt/tomcat/6.0.29/apache-tomcat/bin/catalina.sh stop ssh -t remoteserver sudo sh /opt/tomcat/6.0.29/apache-tomcat/bin/shutdown.sh
I check log file also..when i am executing tomcat start there is no log entry in log file
Using CATALINA_BASE: /opt/tomcat/6.0.29/apache-tomcat-6.0.29 Using CATALINA_HOME: /opt/tomcat/6.0.29/apache-tomcat-6.0.29
We have three production websites running on RHEL 3 AS running tomcat 5. After a reboot last night Tomcat will not start and has the following in the catalina.out log:
Mar 20, 2011 4:09:31 PM org.apache.commons.digester.Digester startElement SEVERE: Begin event threw error java.lang.NoClassDefFoundError: org/apache/naming/resources/ProxyDirContext at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) at java.lang.Class.getConstructor0(Class.java:2699) at java.lang.Class.newInstance0(Class.java:326) at java.lang.Class.newInstance(Class.java:308) .....
I have spoken with our Java Developers and they seem to think it is something up between httpd and tomcat at an OS level. Since Tomcat is not starting and giving an error that it is all ready running, I think you have a stale lock file. Look for the file /var/run/tomcat5.pid and cat or less it to see what the PID number is. If it matches the error, then delete the file and try to start Tomcat again. It should start this time.
Most common problem with Tomcat5. Try following : 1) Search PID in /tmp, if found delete it or else stop your tomcat. 2) Undeploy your application 3) Check out this link [URL] to know what causing tomcat to generate this error.
If none of them work then check your application configuration settings. [URL]. When I do start tomcat it appears to start:
[root@RPSI-2 san00]# service tomcat5 start Starting tomcat5: Using CATALINA_BASE: /usr/share/tomcat5 Using CATALINA_HOME: /usr/share/tomcat5 Using CATALINA_TMPDIR: /usr/share/tomcat5/temp Using JAVA_HOME: /usr/java/jdk1.6.0 [root@RPSI-2 san00]#
But then I try to find if it is running via ps -ef | grep tomcat5, I only receive my query. I perform the same query on Java and it also only returns my query.
I've got a server that runs on Ubuntu Server 11.04 amd64.
I've installed Tomcat 6 and Apache 2 servers.
On Tomcat, I installed Liferay portal as a WAR. I can access to my portal with the following address : http://localhost:8080/lportal
I would like to associate a domain name to the "/lportal" context so that I could access my webapp with the "http://my.domain.com" URL. To make it short, I'd like to access the webapp on "http://localhost:8080/lportal" with "http://my.domain.com".
I have a site [URL] right now what you are seeing is a default Tomcat6 page. I am using mod_ajp as a front end and Apache vhost configuration for same is
Code: <VirtualHost *:80 > ServerName mysite.com ServerAdmin webmaster@localhost ProxyRequests off <Proxy *> Order deny,allow [Code]....
I have FC13 with apache up and running. I need to run tomcat to do some dynamic web with eclipse, I checked my setup and noticed that I already have tomcat5 in add/remove software as installed bu can not find any etc/tomcat and not able to find how to test. I went through the FC13 documentaion, nothing is mentioned abou apache tomcat setup finalizing and testing that ships with FC13 it works. I googled and found some docs around setup tomcat6 or tomcat 5 but not how finalize the one shipped with FC13.
I have installed apache tomcat 5.5.27 in centos5. I edited the server.xml file also. The startup.sh and shutdown.sh commands are working fine. But tomcat is not opening in the browser. Can you suggest me something or tell me the steps involved in installing tomcat. Is admin.tar.gz of apache tomcat required for its working?
When i starts it for the first time,my sites getting loaded fast when requested through browser,but slows down gradually. what could be the reason, my cpu load seems ok. Because i have another site hosted through apache in the same server and its getting loaded fast. so what could be the issue.
I'm trying to set up Apache Tomcat with virtual hosting. I've used Caucho Resin before but not Tomcat...and I've run into what appears to be (from Google at least) a rather common problem with Tomcat in that any properly packaged classes under WEB-INF of the default virtual host or the named host are not found and Tomcat complains of a class that "cannot be resolved to a type". I researched this error on Google and the consensus seems to be that: -
- You need properly packaged classes as classes in the default package are no longer allowed. I have done this.
- You need to either fully declare the packaged class to make an instance of it within the JSP or include the via an import statement at the top of the JSP. I have done this.
- In the web.xml for the Tomcat server instance (under $CATALINA_HOME/conf/web.xml) you need to set the servlet mapping for JSPs fork init-param to "true". I have done this also.
Yet the problem persists and I have found no solution. So I can only assume I'm missing something obvious and fundamental. My configuration is as follows: - I have two virtual hosts - one as the default virtual host and another as a named virtual host.
$CATALINA_HOME/webapps/localhost <--- Default host. $CATALINA_HOME/webapps/www.easicasino.com <--- Named host. The logic being that the URL IP address of the server will hit the default webapp and the URL hostname with hit the named webapp. This appears to work with just JSPs.
My $CATALINA_HOME/conf/server.xml looks like this: -
Whenever I am starting Tomcat5 service in RHEL5 it is showing that it is starting but after some time (after 5 sec.) the status it is showing that lock file found but there is no such process for PID * (where * = different PID no.) and tomcat is not working.
