Sergey Beryozkin commented on CXF-6190:
---------------------------------------
I think I know what it is; introduce an interface like Injectable, have a
"@Context setHttpServletRequest(HttpServletRequest req)" on that interface and
have your service bean implementing it. This should fix it. Your service bean
is most likely a proxy object
> HttpServletRequest injection via Context in setter

> I'm trying to inject HttpServletRequest to my JAX-RS resource via @Context
> annotation. It works fine if I inject it via method parameter. But I don't
> want to "mess" my interfaces with that so I'd like to inject it via setter.
> I use this simple method (I'm using Kotlin but I the issue should be the same
> for Java):
> {code:java}
> var req : HttpServletRequest? = null
> Context
> fun setRequest(req : HttpServletRequest) {
> this.req = req
> }
> {code}
> The thing is, that the setter is called via reflection in
> org.apache.cxf.jaxrs.utils.InjectionUtils in method injectThroughMethod. The
> method name is correct but as parameter value is instance of
> ThreadLocalHttpServletRequest which clearly is not HttpServletRequest (it is
> not inherited class) so this gets thrown:
> java.lang.IllegalArgumentException: object is not an instance of declaring
> class
