Hi,
Thanks Dan, he found a way to fix the issue.
The servlet constructor has been changed to:
public MyServlet(MyRestApi restApi, DestinationRegistry
destinationRegistry, Bus bus) {
super(destinationRegistry, false);
this.restApi = restApi;
this.setBus(bus);
}
and the bean registering the servlet has been changed to:
MyRestApi restApi = new MyRestApi();
Map<Class<?>, Object> extensions = new HashMap<>();
DestinationRegistry destinationRegistry = new
DestinationRegistryImpl();
HTTPTransportFactory httpTransportFactory = new
HTTPTransportFactory(destinationRegistry);
extensions.put(HTTPTransportFactory.class, httpTransportFactory);
extensions.put(DestinationRegistry.class, destinationRegistry);
Bus bus = new ExtensionManagerBus(extensions, null,
getClass().getClassLoader());
org.apache.cxf.transport.DestinationFactoryManager
destinationFactoryManager =
bus.getExtension(org.apache.cxf.transport.DestinationFactoryManager.class);
for (String url : HTTPTransportFactory.DEFAULT_NAMESPACES) {
destinationFactoryManager.registerDestinationFactory(url,
httpTransportFactory);
}
MyServlet restServlet = new MyServlet(restApi,
destinationRegistry, bus);
Thanks to that, I'm able to register several servlets each "isolated"
with JAXRS Server.
I think there are couple of bugs in CXF here. For instance, the
setExtension(null, HTTPTransportFactory.class) to remove the default one
should work, but the default is still in there.
I will propose a PR to improve this.
Regards
JB
