Re: Tomcat 6.0.20 is running out of memory

It might help to look at the contents.jsp of your application, and especially the Java file created from the contents.jsp, at line 174. (you'll need to override the global jspservlet definition in your applications web.xml to prohibit tomcat from removing the java code generated from the jsp files). Reviewing the pagecontext data structure for the contents.jsp might also help. It's a bit curious that the actual JSP row number is not in the log, but then apparently this even has not happened strictly during the processing of that JSP (but still does have some relation to it). As for the question on amount of memory needed by Tomcat, Tomcat doesn't need that much - but your application might. Please, please, try to also look at the application you've built on top of Tomcat, and find out whatever memory requirements it might have. -- ..Juha - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Do you have any other services running on the server that might interfere with this one, by binding to the ports you have configured? Try using the netstat command to see what ports and addresses the server is listening on. http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/netstat.mspx?mfr=true To eliminate the ip4/ip6 problem, you can specify an address=n.n.n.n for the connector to bind to, in server.xml.

other port 80 also port 443 i have enable. So the actul connector

question for singlesignon for vertical cluster
Hi I would like to enable singlesignon on vertical cluster environment [multi-nodes on multiple hosts]. We are using clustersinglesignon under host element, and this works in horizontal cluster, but does not work in vertical cluster environment. Is there any way to make this work as part of tomcat configuration? When the node goes down, and a user may be routed to the node located in a different host, it will ask a user to relogin again under the current setup. We would like to avoid a user for relogging to the application. Anyway, if tomcat does not provide singlesigeon solution for vertical cluster, is there any other open source solutions available?

Re: Tomat monitoring
Hyperic works well for Tomcat monitoring and has native support for it. I prefer this solution. Or you can always create your own custom monitoring solution provided a JMX port is open.

In general, JavaMelody is installed in 10 minutes for a good developer (as JavaMelody is opensource and free, there is no budget to find).
