> Where is that Tomcat from ? how was it installed ? how is it being started ?
I've used this tutorial to install Tomcat: http://community.webfaction.com/questions/4116/install-tomcat-howto-or-step-by-step-tutorial It's started with ~/webapps/tomcat/bin/shutdown.sh Alfredo 2012/2/14 André Warnier <a...@ice-sa.com>: > Alfredo Alessandrini wrote: >> >> Hi, >> >> I'm running tomcat 7.0.25 in a shared server (centOS 64bit). >> >> Memory limit for my account is 256m. >> >> I'm running tomcat with this settings: > > > No, you are not.
