Separate bus instances are created for the CXFNonSpringServlets init,
but what apparently blows up is the create/use/start of more than one
org.apache.cxf.endpoint.ServerImpl instance at: at
org.apache.cxf.endpoint.ServerImpl.start(ServerImpl.java:123).
Any insights on how to avoid/work around this?

If you have separate CxfBus'es per servlet it should work AFAIK.
It seems that by default in the superclass
org.apache.cxf.transport.servlet.CXFNonSpringServlet.init(ServletConfig)
the loadBus method is called during init, and that's implemented as:
protected void loadBus(ServletConfig sc) {
this.bus = BusFactory.newInstance().createBus();
}
This seems to be a separate Bus instance (createBus())...apparently of
the same type.
So the two servlet instances do have separate Bus instances, but I
still get the error described.
Thanksinadvance,

Hi,
Using OSGi HttpService, if I register more than one instance of
CXFNonSpringJaxrsServlet...i.e. at different aliases...then I get an
exception. For example if I have two aliases
'/foo' -> instance 1 of CXFNonSpringJaxrsServlet
'/bar' -> instance 2 of CXFNonSpringJaxrsServlet
on the second call to httpService.registerServlet I get exception and
stack trace below.
Is there a way to create/configure/register multiple
CXFNonSpringJaxrsServlet instances...and/or the underlying
JAXRSServerFactoryBean so that they don't conflict in this manner? Or
is there some other cxf jaxrs servlet/bean classes that would allow
this?
Thanksinadvance,
Scott
