Re: single instance of background job?
Hi, This should be strait forward if you use terracotta. If you have a NFS that all Tomcat instances share, using FileChannel::lock is way cheaper than any other solution. -lg On Sun, Jan 11, 2009 at 2:30 AM, Rusty Wright wrote: > This isn't really a Tomcat question I'm guessing but I don't know where else > to ask. > > In our setup we have multiple Tomcats behind a load balancer.

Linux Runtime Script
Hi, Does anyone has a Linux script to run Tomcat as Linux services, i.e. the runlevel scripts ? I have tried to make one, but in case there is a proven script that has been deployed somewhere... can someone please share ? Thanks, Feris
Re: Implementing service chaining with Tomcat6
What options are available to you to determine if the daemon is ready? For example, does it create a lock file? If so, you could modify your tomcat startup script in /etc/init.d, the one that calls /usr/local/tomcat/bin/startup.sh, and have it check if the daemon is ready and wait until it is, then when it is proceed and start tomcat. For example, here's a little /bin/sh script that waits for the file /bin/zzz to be created and sleeps 5 seconds and keeps checking: while test ! -f /tmp/zzz do echo "sleeping for 5 seconds" /bin/sleep 5 done echo "here we go" uma...@comcast.net wrote: I am using Tomcat6.0.14 with Jdk1.6 on Linux RH4.

single instance of background job?
This isn't really a Tomcat question I'm guessing but I don't know where else to ask. In our setup we have multiple Tomcats behind a load balancer. I have a background task that will run once a day, via Quartz. All Tomcats will be using the same war so they will all run the job, but I need it so only one of them runs the job. I'm looking for ideas for how to implement this. At the moment all I can think of is to use a table in a database with a unique constraint on a column, and each background process tries to insert today's date (-mm-dd) and the one that succeeds runs the job, and the ones that don't, do nothing.

Hmm. A couple. 1. Is the XML file it is complaining about valid? 2. Can you build a simple test case? If so, open a bugzilla entry and attach your test case.

Mark, I checked out rev 733300 from /tomcat/tc6.0x/trunk, built it and the relase, and used an unzipped copy of apache-tomcat-6.0-snapshot. Unfortunately, the same error still happens when I start up my webapp: ERROR org.apache.commons.digester.Digester - Parse Error at line 405 column 17: The content of element type "struts-config" must match "(display-name?,description?,data-sources?,form-beans?,global- exceptions?,global-forwards?,action-mappings?,controller?,message- resources*,plug-in*)". org.xml.sax.SAXParseException: The content of element type "struts- config" must match "(display-name?,description?,data-sources?,form- beans?,global-exceptions?,global-forwards?,action- mappings?,controller?,message-resources*,plug-in*)". at org .apache .xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) ..etc...

For Tomcat 6 and earlier you'll need to do this yourself. I don't know how easy this will be until we have written the code for Tomcat 7. > 3/ detect a smartcard removal This could be tricky. It depends what the browser does when the smart card is removed. I think, based on a previos thread, the SSL session and connection remain valid so tere is no way for Tomcat to detect this.

If you want to apply settings to every content, put them in CATALINA_HOME/conf/context.xml, not server.xml Also, securePagesWithPragma="false" is usually a better option than disableProxyCaching="false" Mark - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I agree with Charles.
But, to note: the count of MimeHeaderField instances mentioned in the
message is of the same range as the count of Cookie instances. Thus I
think that all those header fields are derivatives of the enormous
count of cookies that your application created.
I remembered about the following incident from two months ago, when
programming error caused a session to be reestablished many times in a
row:
http://www.nabble.com/multiple-Set-Cookie-headers-in-initial-http-response-td20437761.html
("multiple Set-Cookie headers in initial http response").
