Mike Edwards commented on TUSCANY-3123:
---------------------------------------
Design approach:
Build a single JAR containing the implementation-bpel-runtime classes PLUS the
ODE JARs and a selected set of the ODE dependency JARs.
The ODE and ODE dependency JARs are then also placed into the Bundle-Classpath:
attribute of the MANIFEST.MF so that all the classes from those JARs are all
loaded by the classloader of the implementation-bpel-runtime bundle, so
avoiding the problems of not finding the provider classes and also not
requiring us to produce specialized MANIFEST files for each of these
non-Tuscany JARs.
Note that when not running under OSGi, these embedded JARs are ignored.

> Project: Tuscany
> Issue Type: Bug
> Affects Versions: Java-SCA-2.0
> Reporter: Mike Edwards
> Assignee: Mike Edwards
> Fix For: Java-SCA-2.0
>
>
> implementation-bpel-runtime has a major dependency on the Apache ODE project,
> which provides the runtime BPEL execution engine required to run BPEL
> processes.
> As well as the direct dependencies on ODE modules, ODE itself has a large web
> of dependencies on modules from a range of other sources.
> The problem with ODE and its web of dependencies is that very few of them are
> built for OSGi and simply using the individual JARs causes classloading
> failures in many places. One of the biggest issues is that there are API /
> Provider pairs that use the META-INF/services approach to loading the
> provider classes for the API.
> This requires that special handling is done for the
> implementation-bpel-runtime module in order for it to run successfully under
> OSGi.
