[jira] Updated: (SM-396) classloading issue in servicemix-jsr181 -
thread context classloader not set to serviceunit classloader
[ https://issues.apache.org/activemq/browse/SM-396?page=all ]
Renaud Bruyeron updated SM-396:
-------------------------------
Attachment: fix-jsr181.txt
This patch fixes the issue revealed by the previous attachment.
It works by setting the TCL to be the classloader of the xbean deployment unit (via XBeanServiceUnit.getConfigurationClassLoader()) before invoking Jsr181Endpoint.registerService(). The TCL is reset to its initial value after the call.

> the registerService() method in Jsr181Endpoint is running with the servicemix classloader as the thread context loader, instead of the serviceunit classloader.
> This creates problems when xfire tries to load interface classes referred to by the @WebService(endpointInterface="...") annotation on the implementation class. These classes are loadable via the serviceunit classloader, but not via the main classloader.
> This is what I see during deployment of the soap-binding example:

> If I replace the TCL with ((XBeanServiceUnit) getServiceUnit()).getConfigurationClassLoader() right before the call to factory.create(serviceClass, ...) then all is well.
> The patch attached modifies the soap-binding example to deploy a jsr181-annotated service as well. This triggers the bug.
