Web Service calling COM+ components

P: n/a
I have built a XML Web Services that needs to call a COM component
registered im Component Services. When calling the methods from XML Web
Service, that in turns calls the methods from COM+ component, I get a
InvalidCastException - "QueryInterface failed for interface...".
I already read several articles about this issue and some of them told me
that is possible make calls to COM+ components from XML Web Services, but the
presented solutions did not work in my case. One if these articles advised me
about the threading model of Web Services (MTA) and COM (STA).
Anyone can help me to solve this problem?
