For each image I would get a small red x. When I hit refresh and it then display them.
Comments like this on Confluence web site for example explain: After a bit of Googling came across this: "Apache Portable Runtime to provide superior scalability, performance" for Tomcat 6. There are comments that when using the APR Tomcat will server static content on par with Apache (httpd) server speeds - though I haven't been able to personally verify this just yet. Or from the Tomcat site itself http://tomcat.apache.org/tomcat-5.5-doc/apr.html: Tomcat can use the Apache Portable Runtime to provide superior scalability, performance, and better integration with native server technologies. The Apache Portable Runtime is a highly portable library that is at the heart of Apache HTTP Server 2.x. APR has many uses, including access to advanced IO functionality (such as sendfile, epoll and OpenSSL), OS level functionality (random number generation, system status, etc), and native process handling (shared memory, NT pipes and Unix sockets). >These features allows making Tomcat a general purpose webserver, will enable >much better integration with other native web technologies, and overall make >Java much more viable as a full fledged webserver platform rather than simply >a >backend focused technology. > So as to say the Tomcat group did not want to compete why build the APR? In either case it does not matter for me but I do appreciate the feedback.

Upgrading is a good idea, but is unlikely to magically fix everything.

APR != httpd The "Tomcat Group" neither developed APR nor did they do it to undercut anything the httpd group is doing. On the contrary, libapr is a project to help many other projects, including httpd itself. http://apr.apache.org/ http://apr.apache.org/projects.html http://en.wikipedia.org/wiki/Apache_Portable_Runtime > What little info I could find seems to indicate APR uses the ROOT directory > under Webapps for html based apps. APR does nothing of the sort. APR essentially provides two major capabilities to Tomcat: 1. SSL services using OpenSSL library instead of Java-based SSL 2. "Sendfile" services to serve static content directly from disk-to-socket with minimal overhead Both of these features are configured on a <Connector> in Tomcat and will work with any webapp deployed into the container. It has nothing to do with ROOT or any other specific webapp. > I will probably go back to Apache Web server as a separate tier.

Apache httpd + Tomcat will always be slower than simply using Tomcat + APR/sendfile because of the overhead involved in forwarding the requests back and forth. The only exception might be a site which is almost exclusively static content and only one or two dynamic resources. In that case, I might ask why that person was using Java in the first place ;) There certainly are reasons to use Apache httpd out in front of Tomcat, but performance isn't one of them. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxEyOAACgkQ9CaO5/Lv0PD+ngCdGoi80vMKrjB7UMP9kQKyLaS3 X/UAnjslqqAnc7796Xr14ic5cDEckPYl =vtNH -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
