[Wrapper-user] Trying to understand a simpleapp issue.

Hi, I am trying to use the Simple wrapper approach to launch a webserver and am running into issues. I was wondering if anyone could offer up some suggestions of where to look etc. First: I am using Jruby and the glassfish gem which launches the glassfish server. Second when I setup using the "simple wrapper" approach It looks like things are starting up... then I get a timeout in the wrapper log. I'm not 100% sure that this approach is the right one to be taking here. but it seems so close to working :). Without the wrapper I launch glassfish thusly: jruby -S glassfish this produces a process : java -client -Djruby.memory.max=500m -Djruby.stack.max=1024k -Xmx500m -Xss1024k -Djffi.boot.library.path=jruby-1.5.0/lib/native/x86_64-Linux -Xbootclasspath/a:jruby-1.5.0/lib/jruby.jar -classpath jruby-1.5.0/lib/jna.jar:jruby-1.5.0/lib/profile.jar: -Djruby.home=jruby-1.5.0 -Djruby.lib=jruby-1.5.0/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main -S glassfish I'm thinking that the problem may be that launching this app never returns... or ... I know in the past jruby stuff I've done does not launch any non daemon threads and this interfered with the wrapper's ability to keep my app running. Any thoughts? here is a snippet of the wrapper log file following this is my wrapper.conf file : ERROR | wrapper | 2010/07/27 11:04:07 | Startup failed: Timed out waiting for a signal from the JVM.
