---------------------------------
Affects Version/s: (was: (Java) V4 4.3.0)
V2 2.0.8
> Support of OSGi bundle wrapping
> -------------------------------
>
> Key: OLINGO-1140
> URL: https://issues.apache.org/jira/browse/OLINGO-1140
> Project: Olingo
> Issue Type: New Feature
> Components: odata2-core
> Affects Versions: V2 2.0.8
> Reporter: Johannes Hoenger
>
> *Context*
> We as OSGi developers face a challenge when using third-party libraries like
> Olingo that OSGi bundles may not be provided.
> Since Olingo does also not provide a bundle we opted for the most common
> solution. We wrapped the Olingo library using [Apache
> Felix|http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html].
> For more details about wrapping please refer to this link [Wrapping Libraries
> to OSGi Bundles|http://bnd.bndtools.org/chapters/390-wrapping.html] and
> [Creating wrapper OSGi
> bundles|https://cwiki.apache.org/confluence/display/SMX4/1.+Beginner+-+Creating+wrapper+OSGi+bundles].
> *Request*
> An inherent property of the wrapping is that the namespace of the wrapped
> artifact changes. This is usually not an issue.
> However, when in the code is a package name hardcoded which leads to issue in
> our software component.
> The issue occurs at line 63 in the class RuntimeDelegate. Please refer to the
> following link
> https://github.com/apache/olingo-odata2/blob/b33cdc411ac8731162266ebb19ae97a90ca88be9/odata2-lib/odata-api/src/main/java/org/apache/olingo/odata2/api/rt/RuntimeDelegate.java#L51-L76
> The aforementioned lined throws in our OSGi components the following exception
> {code:title=exception.log|borderStyle=solid}
> Exception:
> org.apache.olingo.odata2.api.rt.RuntimeDelegate$RuntimeDelegateException:
> java.lang.ClassNotFoundException:

> {code}
> This line is, as far as we can tell, the only line which is incompatible with
> the OSGi wrapping approach. Is is possible to provide a solution for this
> case?
