Re: Swing Apps & OSGI...
That is indeed very similar to the solution I've used in the past. By having to sign the jars, you mean the jars that make up the "custom launcher", so you can run web start out of its normal sandbox, right? In any case we never needed to sign our bundles.

Re: Swing Apps & OSGI...
Yep - we have it working fine, albeit we use a very "thin" webstart layer which is really just a custom launcher. The launcher loads the usual OSGi properties via URL, which amongst other things then installs and starts the various bundles, whose location are also specified via URLs in the auto.installl an auto.start properties. So in truth - it's only really the launcher that actually gets loaded via webstart, the rest of the application loading is done via OSGi - which in our case is exactly what we wanted. We found we needed to sign all of our JARs to make the process work, to meet WebStart security policy which gets inherited by the VM OSGi runs in Regards -- Rob On 16/06/2010 7:41 PM, Tony Anecito wrote: Has anyone been able to get OSGI working with java Web Start?

Re: Swing Apps & OSGI...
Thanks Marcel that confirms what I have read. I had heard no one has tried using JWS + OSGI but I asked that question many months ago. I tried using that combination but ran into issues and had some other deadlines to get through first. Have you or anyone else seen an example you can point me to with this combination? I will try again since I have some time. Regards, -Tony - Original Message From: Marcel Offermans To: users@felix.apache.org Sent: Wed, June 16, 2010 2:31:55 PM Subject: Re: Swing Apps & OSGI...

You can use web start to bootstrap the framework plus some kind of launcher or management agent that understands the web start environment (perhaps reading some configurable properties from the JNLP file, etc.) Since OSGi needs a local bundle cache, you cannot simply use the sandboxed, unsigned option of web start. This management agent, when started, will then fetch the other bundles from the server (this has nothing to do anymore with web start). You probably want to use an algorithm to detemine a proper location for the bundle cache (that depends on the operating system and logged in user). > Or is there a different recommendation for intial deployment for Swing-OSGI. > Seems like OSGI is good for after you deploy but not the model for initial > deployment for java apps.

OSGi by itself cannot bootstrap the JVM and there is no standard mechanism to bootstrap the installation of an OSGi implementation either, but combining JWS+OSGi definitely makes sense if you ask me.
