JSF/Icefaces RequestDispatcher

I am trying to write a component in JSF to read legacy开发者_开发百科 JSP files. I am using RequestDispatcher.include to do this...The only problem is that externalContext.getRequest().getRequestDispatcher(...) returns an UnsupportedOperationException in Icefaces.

Is there a way round this?

Thanks.
