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

Jay,
You were very close.  The configured "main class" needs to be a Wrapper
helper class or a user class which implements the WrapperListener interface.

Please try the following:
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
wrapper.app.parameter.1=org.jruby.Main
wrapper.app.parameter.2=-S
wrapper.app.parameter.3=glassfish

The following property also didn't have a valid value.  Try this:
wrapper.java.command.loglevel=INFO

Please let me know how this works for you.

Cheers,
Leif
