Hi Freeman Fang, thank you for your response.
How would you do it? What do you mean with "refer to the bean directly"? It is a service and still has to be a service because another bundle also uses it. So how do I get the one service instance that is registered in the blueprint container? To the "chicken-egg" problem: I saw in the IBM tutorial that it is possible to use the blueprint "ref" property to refer to a blueprint bean of the same bundle. http://www-01.ibm.com/support/knowledgecenter/SSCKBL_8.5.5/com.ibm.websphere.osgi.nd.doc/ae/ca_blueprint_references.html?lang=en If I understood it right, this is possible by only using the ref-property with the desired bean ID and NOT including the reference tag: <reference id="containerManagerRef" interface="de.kisters.project.domain.api.session.container.IContainerManager" availability="mandatory" /> Thank you and regards Tim -------------------------------------------------------------------------------------------------------------------------------------------- Andy Schmidt - KISTERS AG - Pascalstraße 8+10 - 52076 Aachen - Germany Handelsregister Aachen, HRB-Nr. 7838 | Vorstand: Klaus Kisters, Hanns Kisters | Aufsichtsratsvorsitzender: Dr. Thomas Klevers Phone: +49 2408 9385 -449 | Fax: +49 2408 9385 -555 | E-Mail: [email protected] | WWW: http://www.kisters.de -------------------------------------------------------------------------------------------------------------------------------------------- Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.

Your way run into the chicken-egg problem, that said, your bundle depend on a service provided by the bundle itself. －－－－－－－－－－－－－ Freeman(Yue) Fang Red Hat, Inc.
