Ivan Churkin commented on TUSCANY-2346:
---------------------------------------
It looks like this problem may occurs only in OSGi application, because
multiple classloaders.
I tested with simple application and all was ok.
Please look at the workspace attached. Its not complete testcase but it create
required JAXB object.
Unit test is in the bundle "org.eclipse.eilf.jaxbsample.test"
It creates JAXB object by loading classes from two different bundles
"org.eclipse.eilf.jaxbsample.root" and "org.eclipse.eilf.jaxbsample.sub"
The classloader of the second bundle able to load all classes
but the classloader of root class located in the first bundle and unable to see
classes located in the second bundle.
That is the problem
Is you will try to pass object through SCA it will cause error mentioned.

> Key: TUSCANY-2346
> URL: https://issues.apache.org/jira/browse/TUSCANY-2346
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Data Binding Runtime, Java SCA OSGi Integration
> Affects Versions: Java-SCA-1.2
> Environment: databinding-jaxb, OSGi (but i think it should affects
> non-OSGi version too)
> Reporter: Ivan Churkin
> Attachments: JAXBDataBinding.java, workspace.rar
>
>
> There is a JAXB feature to create JAXB context by specifying the whole array
> of all mapping classes. Tuscany databinding-jaxb plug-in unable to work with.
> As a result, when application uses SCA for transmitting objects created by
> specifying complex JAXB context it crashes.
> This plug-in (databinding-jaxb) creates context for marshalling on very
> simple way. It gets class of root object and asks for JAXB to create context
> by providing it. So it supports only simple/default JAXB contexts.
> Its suggested more sophisticated procedure.
> 1. try to use default/simple context
> 2. if it does not work, to collect all JAXB related classes used in instance
> object and its properties/subobjects by reflection and to create context by
> array.
