I’m still very much a newbie, so please have patience with me. I’ve been following along in The Book of Vaadin and I have Tomcat v8.0.18 installed correctly. It starts up correctly, too, but only when started up on its own.
When I attempt to run (or debug) a project—even the default one that is created with the Vaadin Plug-in for Eclipse when I have it create a new project, I get a mass of errors as it’s trying to start Tomcat:

at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:485)The only clue I have is that, when I try to run/debug a project, Eclipse adds that project to the server as a “resource”. But if I expand the tree to show the server’s resources in Eclipse’s Servers tab, then delete that resource, I can at least start the server fine. What gives?
The interesting bit is that it was working yesterday for a short while. But when these error messages started appearing, I’ve done all I can think of, such as deleting all the servers in Eclipse and then adding it back again as a new server, etc. Still nothing. Can anyone please take some time out to help me figure out what’s going on and, more importantly, to resolve it?
