thanks a lot for your help, Guillaume I think i has understood your mind now, I will provide two different NamespaceHandlers, one for spring-dm and one for geronimo, according to the same xsd file.
But there are still some problems, the geronimo has a blueprint_ext.xsd while the springdm provides the property_placeholder with Spring_context.xsd, the two element definations are not equivalent, i will provide a new schema file which is the intersection of the two old ones. After i finish these schema files and namespaceHandlers, I plan to zip them as bundles respectively, and acting as a fragment, seting host-bundle to geronimo_bp.jar or spring-osgi-core.jar while we need switch between the two BP implementation. Because the custom namespace Handler for geronimo need to be registered as an service in OSGI-INF/*.xml, and springdm's need to be registered in spring.schema as well as spring.handler. is this ok? or do you have any suggestions? thanks! best regards! 2010/4/8 Guillaume Nodet <[email protected]> > No, we can't have a neutral namesapce handler, but we could provide two > different handlers, one for spring-dm and one for blueprint.
