[rules-dev] Problem with M2 reading package from Guvnor via RuleAgent

[David Sinclair]

I have upgrade my application to use the milestone 2 code and am having a
problem loading a package from guvnor via the rule agent. I am getting a
class not found exception for org.drools.rule.PackageCompilationData. Here
is the stack from the app. Looking at the code it appears the
PackageCompilationData has been removed.

RuleAgent(Drools) INFO (Wed Oct 01 11:55:19 EDT 2008): Configuring with
