[rules-users] Re: drools-solver -- logger error (slf4j binding)?

[Andrew Waterman]

Thanks Geoffrey!  I patched this yesterday with slf4j-jcl and slf4j-nop for
no loging.  I'll post the mavne dependencies later this morning in case
others wish to use non-log4j implementations. :)  I did noticeas well  that
the "scoreCalculator" global is referenced by name from the solver.  Want me
to file a jira issue on that?  It seems strange that the variable name
shoudl be static like that to me.

best wishes,

Andrew
