Re: [Wrapper-user] Launching but not starting a service

[Leif M. <le...@ta...>]

Jimmy,
    From the error message, by guess is that the java executable is not 
being found
when run as a service.   The way to quickly solve problems like this is 
to set the
wrapper.debug=true property and attempt to start your service again.   
In most
cases, it will then be obvious what the problem is.   If you could post 
the resulting
DEBUG output from a single invocation of the Wrapper, I should be able to
tell you what the problem is.

    Make sure that the JAVA_HOME and JWrapperPath environment variables
have been defined as system level environment variables.

    Cheers,
    Leif
