There's no possibility to get that object with the method getResources(HTTPServletRequest) because the servlet does not extends an Action class. Is there a way t...
This is just a curiosity question. I know that Spring can be used in a Struts ActionServlet (sp?) via certain means, but I was wondering if there was a HandlerAdapter that allowed old Struts code to be ported immediately to a Spring DispatcherServlet to use the DispatcherServlet as the front controller. ...

Once upon a time, Struts was the default choice for a Java web framework. I have no data on this, but I imagine that Struts2 is currently widely used for legacy reasons, only because former Struts projects have been migrated to it. Is Struts 2 really the best choice for a new project? What other web frameworks out there are most popula...
