Hi,
I prefer to have the design discussion be carried on the tuscany-dev ML
instead of JIRA :-).
We already have the maven-bundle-plugin that do all the tricks to enable
OSGi for 3rd party jars (run mvn -Peclipse under sca/distribution/all),
including:
1) Generate MANIFEST.MF for plain jars in the distribution
2) Merge multiple jars into one bundle
3) Override MANIFEST.MF for 3rd part bundles with problematic MF
Then these bundles can be set as the Eclipse PDE target platform which is
used to resolve the bundle dependencies for Tuscany modules. I have fixed
the Import-Package under [1] and verified that it works in PDE and Equinox
console.
Do you have a test case that I can use to validate the impl.bpel under OSGi?

Thanks,
Raymond

Subject: [jira] Commented: (TUSCANY-3123) Enable implementation-bpel-runtime
for OSGi on SCA Java 2.0
[
https://issues.apache.org/jira/browse/TUSCANY-3123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12724456#action_12724456 ]
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.
Enable implementation-bpel-runtime for OSGi on SCA Java 2.0
-----------------------------------------------------------
Key: TUSCANY-3123
URL: https://issues.apache.org/jira/browse/TUSCANY-3123
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.
