Hi, i have some troubles while trying to use some classes (e.g.: Commands) from the org.drools.core Bundle. I can't import packages or set the core bundle as required: Import-Package: org.drools.command.runtime;version="5.1.1", ... Error in Manifest.MF: Bundle 'org.drools.core' exporting package 'org.drools.command.runtime' is unresolved But the Bundle can't be unresolved because it is startet correctly. At Bundle Validation he has an "Uses Package Conflict" concerning: com.sun.tools.xjc. Can someone help me or give me a tip? Kind regards, O.S. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/OSGi-Unable-to-Import... Sent from the Drools - User mailing list archive at Nabble.com.
