Problem installing bundles using streams

[gnodet]

I'm trying to have Karaf run on top of JBOSGi but found a major problem.

See https://issues.jboss.org/browse/JBOSGI-600

When installing a bundle from a stream, a vfs url is created and fail, because vfs handler isn't registered.

After fixing the deployment issue by replacing URL to URI in BundleInfo and VirtualFileDeployment, the bundle is successfully installed, but can't be scanned because the stream url is still used instead of pointing to the copy in the cache.

However, before trying to fix further those issues, I'd like to make sure I didnt miss anything.  If the vfs urls supposed to be really used at runtime ? I.e. should the vfs url handler be registered at some point or is that cases that haven't been tested because I'm not running in the usual jboss environement ?

Cheers,

Hi Guillaume, good to see you here.

What are you actually passing in to BundleContext.installBundle(String, InputStream)? Perhaps you can explain the sequence of actions that get you there. I assume you have some provisioning bundle that is trying to install other bundles. I'm also happy to look at some karaf branch if you have one.

Sure, replicating the problem is quite easy.

Download a karaf distribution such as:

    http://repo1.maven.org/maven2/org/apache/karaf/apache-karaf/2.2.9/apache-karaf-2.2.9.tar.gz

I've been using the 2.3.x branch myself, but the above distribution will exhibit the same problems.

Though testing with 2.2.9 for this very message, I found i needed a better fix for JBOSGI-599, see

   https://github.com/gnodet/jbosgi-framework/commit/d2705cbee12ae3816bf423119c33e45ab3e28539

You can find the maintenance branch at

   https://github.com/apache/karaf/tree/karaf-2.2.x

The first exception occurs in the following code:

   https://github.com/apache/karaf/blob/karaf-2.2.x/main/src/main/java/org/apache/karaf/main/Main.java#L611

The actual call looks like:

   context.installBundle("mvn:org.ops4j.pax.url/pax-url-mvn/1.3.5", inputStream)

The location is a maven url handler but should not really be used by the framework.

I'm not really sure what the problem is, because I don't really understand if the use of the vfs style urls is expected or not.

Anyway, let me know if you need anything.
