Subject Re: [RPM Installer] Generic start/stop shell script
Date Thu, 29 Mar 2007 05:37:39 GMT
No I have not tried it but I'm wondering if this is a launcher for a class
and not the jvm.  It sounds like it's more like the daemon bootstrapper
code.

However give it a try and let me know I could be totally wrong about it.
Just guessing from past history playing with the Tomcat launcher code while
formulating the daemon bootstrappers.  There's a lot that's borrowed from
there I think if this launcher thingy is what I think it is.
