ApacheConfig returns ClassCastException for mod_jk
Hi, We want to configure tomcat 5.5.17 with mod_jk and change server.xml as below: The above changed was mentioned at "http://tomcat.apache.org/connectors-doc/howto/apache.html"; to create a mod_jk.conf-auto file. But, we get an error which sayes: java.lang.ClassCastException: org.apache.jk.config.ApacheConfig at org.apache.catalina.startup.LifecycleListenerRule.begin(LifecycleListenerRule.java:96) at org.apache.tomcat.util.digester.Digester.startElement(Digester.java:1275) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:533) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanStartElement(XMLDocumentFragmentScannerImpl.java:878) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1693) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) Any comments!

Re: URGENT HELP NEEDED: mod_jk loadbalancing issues
Hi, First of all - thanks Rainer for willing to look into this issue. Environment description: Web Server: Apache 2.0.52 mod_jk: 1.2.15 OS: RedHat ES 4.2 App. Server: Tomcat 5.5.15 Cluster topology: 4 webservers with mod_jk doing sticky loadbalancing into 10 tomcats MOD_JK Configuration: Pretty much basic mod_jk and Tomcat settings for AJP13 Description of the issue: Under very heavy loads for our standards (about thousand of concurrent users) we start seeing errors (listed at end botton of this e-mail) in the mod_jk error log. Our concern is mod_jk behavior on the web server. We closely monitor apache and Apache itself is not under heavy stress. However, shortly after we start seeing these messages in the mod_jk's error log, web server becomes unresponsive and we have to re-start it. While the web server server is unresponsive we monitor 8009 port - nothing is going on it. We monitor Tomcats and they are fine. As soon as we re-start web servers traffic resumes. Then under heavy loads things break again We are planning on increasing the number of max threads on the Tomcats' AJP connector to imrpove the throughput of the Tomcats. However, our concern is with the web server side lock ups. It seems that mod_jk cannot recover after this oversaturation.

Re: URGENT HELP NEEDED: mod_jk loadbalancing issues
What is your load average under these circumstance? Is each of the 10 tomcats on a seperate physical machine? What are your max thread settings in Tomcat? Are your tomcat machines CPU bound or I/O bound under full load? Alex On 7/9/06, Edmon Begoli <[EMAIL PROTECTED]> wrote: Hi, First of all - thanks Rainer for willing to look into this issue.

users digest attachment problem
Hi, I've subscribed the tomcat users digest mailing list, so that I regulary receive one mail containing the single messages as attachments. Now since the 26.06.2006 the attachments do neither show the subject, nor the from-address any more. All attachments are listed as "Unbenannte Anlage" (unnamed attachment). The last digest I received where this was working correctly is dated 24 Jun 2006 16:42:08. I'm using Windows 2000, MS Outlook 2003. Did something change within the tomcats mailing list around that date? All other digests I receive like jakarta commons or struts are just working fine.

Setting locale for a particular web application
Hello All, We are using Tomcat 4.1.3 . We have 2 web applications running on the same webserver. The problem I'm facing is that I need to change the locale information while instantiating one of these web application. Is such thing possible? I tried setting the JVM opts -Duser.language and -Duser.region in "catalina.bat", but that changes the locale for both web applications (which I don't want). I would really appreciate any help/information in this regard. Thank you, Venkatesh __ Do You Yahoo!? Tired of spam? Yahoo!
