Re: Tuscany in OSGi

[Rajini Sivaram]

Daniel,

>From your stack trace, it looks like Tuscany didn't get as far as handling a
bundleresource:// URL. It looks like "tuscany-sca.xsd" could not be located,
using ReallySmallRuntimeBuilder.*class*.getClassLoader().getResource("
tuscany-sca.xsd"). Do you have Tuscany packaged as a single bundle? There
are still some outstanding issues with Tuscany classloading when Tuscany is
packaged into multiple bundles at the Tuscany module level - eg.
tuscany-sca.xsd is in the default package.

You could still run into the URL issues described in (
http://marc.info/?l=tuscany-user&m=119559170431301&w=2) once you get as far
as loading your composite files. I will raise that as a JIRA to try and get
it fixed. At the moment, you can workaround the issue either by setting a
thread context classloader (for a generic solution) or using the
ClassLoadingHook described by Jason (for Eclipse). Basically the
classloader.getResource() needs to return a file:// or jar:// URL for the
resources loaded from the contribution, when using DefaultSCADomain.
