I have been working for a few days on a new (Windows) system, and
suddenly WEBrick won’t start. Full error text is at bottom of message.
It began after I followed Brian H.'s (terrific!) instructions for
setting up Eclipse w/Rails in Windows
(http://www.napcs.com/howto/railsonwindows.html). The server started
fine from w/in Eclipse when I reached that part of the instructions, but
when I got to the end I found the server broken (hadn’t started the
server in the meantime, so I can’t say for sure when it happened).
WEBrick now doesn’t work from inside Eclipse or from the command line;
identical errors. I tried creating a new rails command-line project in
case the projects inside Eclipse were damaged; no difference.
I also tried rewinding, but even complete uninstall/reinstalls of ruby
and rails don’t fix the problem. These are completely basic projects –
no plug-ins, I haven’t even generated a scaffold or any
models/controllers yet.
Anyone able to shed any light?
