Re: [osgi-dev] wire admin add packages
By wire admin I assume you don't really mean the WireAdmin service [1]. That service is completely on top of the framework and not related to bundle wiring. Here I assume you mean the bundle wiring API [2]. First I will tell you how it can be done, but then I want you to give the reason you need to do this, because there likely is a better way to accomplish what you need. The only way you can dynamically add package imports is to use a WeavingHook [3]. For each bundle class load your WeavingHook.weave method will be called with a WovenClass object. The WovenClass object has a method getDynamicImports [5] that allows a hook to add more dynamic imports to the bundle as needed. The intended purpose of this method is to allow a weaving hook to add more package imports that may be needed by the code that is being woven into the class. But you obviously can choose to do it for any other reason you want to. Keep in mind the dynamic imports added by weaving hooks are not persistent and have to be redone each time a new class loader is created for the bundle (i.e. on framework restart or bundle refresh).

Re: [osgi-dev] wire admin add packages
Ok so weaving is limited to r6.. not good news. I'm working on the JSP case. But I'm going to look at the equinox jsp bundles to see if that can work for us.

Re: [osgi-dev] wire admin add packages
Interesting, I may need that, but I solved the first step at least without it using the Wiring APIs, which are awesome btw. - Ray On Mon, Jun 9, 2014 at 11:12 AM, Thomas Watson tjwat...@us.ibm.com wrote: Note the WeavingHook is also available in R5: http://www.osgi.org/javadoc/r5/core/org/osgi/framework/hooks/weaving/package-summary.html Tom [image: Inactive hide details for Raymond Auge ---06/09/2014 10:07:26 AM---Ok so weaving is limited to r6.. not good news.
