Storing object in context with flow

[Upayavira]

I have an object that is used by all pages to present static data to 
pages using JXtemplate, so

cocoon.sendPageAndWait("page", {"static", 
cocoon.context.getAttribute("StaticObject")});

How can I get an object into the context, once, at server startup, 
without subclassing CocoonServlet?
