Hi All, I am new to drools and I am looking forward to receive help from experts out here. I have created a new drools project where I will be using drools-distribution-5.4.0.Final. I have created three Source folders for drools-compiler-5.4.0.Final-sources, drools-core-5.4.0.Final-sources and knowledge-api-5.4.0.Final-sources. I have imported all the other binaries/JAR's available from the same drools-distribution-5.4.0.Final folder using Java Build path. I have been getting errors in all the three source folders and the errors are related to Activator.java. In all the import statements I am getting an error called The import org.osgi cannot be resolved. import org.osgi.framework.BundleActivator; import org.osgi.framework.BundleContext; import org.osgi.framework.ServiceReference; import org.osgi.framework.ServiceRegistration; import org.osgi.util.tracker.ServiceTracker; import org.osgi.util.tracker.ServiceTrackerCustomizer; I am not sure where to find org.osgi. Any help related to this is greatly appreciated. Thanks in advance, Mallory -- View this message in context: http://drools.46999.n3.nabble.com/Error-in-Activator-java-tp4022753.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
