JAX-RS resource classes and thread-safety

Hi,

The JAXRS spec says that a new Resource object should be created for each request - is this the case in CXF?

From what I understood, this is not what happens?

If you use singleton resource classes then indeed a single instance is 
shared. The injected JAX-RS context instances are thread-safe though, 
but the custom state would need to be protected assuming it;s modified 
after the initialization.

If you need a per-request resource creation then check this section please:
