Thanks, I now have a servlet working as expected.

For anyone else here is some psuedo code:

@Inject
private org.apache.deltaspike.core.spi.scope.window.WindowContext
windowContext;

protected void service(HttpServletRequest request,HttpServletResponse
response) throws ServletException, IOException
{
windowContext.activateWindow( "abc123" );
TabInfo tabInfo =
org.apache.deltaspike.core.api.provider.BeanProvider.getContextualReference(
"tabInfo", false, TabInfo.class );
tabInfo.setImportantInfo( ii );

javax.servlet.RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher( "/detail.jsf?dswid=abc123" );
dispatcher.forward( request, response );
}


-Thanks again
