Re: Hello and Tomcat issues with sticky sessions
Hello gabriel I think you should have the following in your configuration: in de workers definition something like worker.pub-app01.domain=pub-app01-jvm and in your tomcat server.xml Engine name=Catalina defaultHost=localhost jvmRoute=pub-app01-jvm regards Milko Emmerig Gabriel Tabares gabriel.tabares@ roboreus.com To users@tomcat.apache.org 30-06-2010 12:16 cc Subject Please respond to Hello and Tomcat issues with sticky Tomcat Users sessions List us...@tomcat.apa che.org Hi everybody, I have been running Tomcat on production for a few years with no problem but now, after moving to a new company, I am completely unable to get session stickyness working.

placiing content and application on a microsoft DFS solution
Has anyone ever placed an application and its content on a redundant DFS solution? So as when one DFS server fails, another takes over. Does anyone see possible problems with this setup? ie. when dfs server fails does tomcat loose connection to the app or is the failover fast enough. regards Milko Emmerig Please consider the environment before printing this email.

deleted page not immediately invalidated
hello We have a website which has it's content on a filesystem. all pages are jsp, with caching off. when we change a jsp, it get's recompiled at once when refreshing the page, so the new content is displayed. This is correct. now, when we delete a page from the filesystem and we do a refresh, it displays the page, when we do another refresh we get a page not found. I would expect a page not found after the first refresh! What could be causing this behaviour? regards Milko Emmerig Please consider the environment before printing this email.

seperating content from the application
Hello Our current configuration: We are running tomcat 6.0.16 on windows 2003 enterprise. We have a website which consists of an application part and a content part. Both are in the same folder structure, eg. webapps\Root\applicationfiles webapps\Root\content\publications webapps\Root\content\images the application comes as a war file and the content is placed via another process. the folder structure is placed on a windows share. Our current problem: Whenever there is a problem with the share, the application crashes, because tomcat can't find the application files anymore. When the share comes back online, tomcat does not recover from the failure and a restart is the only option. Now I have the following questions: I think separating the application from the content and placing the application local to tomcat (basically on the same machine) will solve the recovery issue. I know placing everything local to the tomcat will be the best way and gives the best performance, but at the moment that is not an option. The questions - Will placing the app local to the tomcat solve the recovery issue? - Is there an easy way to seperate the app and the content, ie. some sort of pathsetting ? regards, Milko Please consider the environment before printing this email.
