tuning to accommodate Apache 2.4 event mpm

Hello All, We recently switched to Apache 2.4 and it's event mpm and are now finding that some of our Tomcat 7 webapps are failing sporadically when accessed via Apache - generally reporting 503s back to the browser. The webapps work reliably when accessed directly from Tomcat. We're using

using log4j in a webapp using embedded tomcat

Hello All, I have a simple program which uses embedded-tomcat (7.0.50) to host a WAR file. The webapp is using log4j and logs correctly when run inside a standard tomcat container. However, when hosted by the embedded-tomcat, the log4j configuration does not appear to be found. I'm specifying

Re: java.net.SocketException: Too many open files

Thanks for your reply Peter. Initially I was assuming that lsof was not showing me files on disk that were being opened and read by servlets. However, I've been unable to reproduce that in a more controlled setting. Since this system has been running for weeks w/o any modification,

JSP: No suitable driver found

reading request parameter invalidates post body

Hello All, I'm using tomcat 6.0.18 and it appears that reading a request parameter like: String param = request.getParameter(param); causes any subsequent attempt to ready the post body to fail: while ((inputLine = reader.readLine()) != null) { sb.append(inputLine); } It doesn't
