It seems that KnowledgeBuilderFactory in api now has a dependency on these sun packages. However the pom declares them as "provided". This seems to imply that drools will only be run in some kind of app-server?? I had to manually add a bunch of dependencies just to get my drools app to compile. What is the rational behind this? -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/5-1-1-import-com-sun-...
