Re: [Wrapper-user] Quartz and "Timed out waiting for JVM Signal"

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

Greg,
What does your wrapper.conf file look like?  Particularly, what is your 
main class?
The most common cause of this problem is specifying YOUR main class as 
the main
class rather than one of the Wrapper helper classes.  Please be sure 
that you have
read over the integration methods.  Most users file Method #1, using the
WrapperSimpleApp helper class to be appropriate.

Cheers,
Leif
