So I'm relatively new to hosting web apps on a linux server, but I'm familiar with hosting services and running file servers just fine on a linux server. I'm going to be involved with Geronimo and Tomcat at work and I can't make sense of what geronimo and tomcat actually do, since they both seem to stem from apache. Googling hasn't brought me anything but long winded industry jargon. Could someone introduce me to what the 2 services provide in simpler terms? why would we want to use them? what are the dependent of/upon? Are there other comparable services available? Hope to get more views here than the other sub.
