After two days pulling my hair out with Jetty 5 I installed Jetty 6 manually.
It works but there's no real way to start and stop it, so I started writing
an rc script. Eventually I figured out it would be almost identical to the
Tomcat script so I've prepared a modified version (below). Thought I'd post
it in case anyone else uses Jetty 6.
As far as I can see it's almost identical to the Tomcat one but there's two
problems:
- stop doesn't work the same (I've had to put a hack in) because $rc_pid is
not being set. no idea why...
- the process in the output of "ps -aux" shows in full command line form, like
this:
jetty 69487 ... 2:57PM 0:05.31 /usr/local/jdk1.5.0/bin/java ...
while the output for Tomcat shows like this:
www 13404 ... 3:13PM 0:02.20 [java]
(Actually I think the second problem is the cause of the first.)
I'm not much of an rc guru. Does anyone know where I'm going wrong?
