Struts Interview Questions and Answers

Ques. Direct Requests to JSPs
Ans.
To take the full advantage of sub-application support, Struts 1.1 stipulates the requirement that all requests must flow through the controller servlet, i.e. the ActionServlet. Effectively, this means all JSPs must be fronted by Actions. Instead of allowing direct requests to any of the JSPs, all requests must go through an Action and let the Action forward to the appropriate JSP.
This is perhaps the biggest impact of migration to Struts 1.1 if you have not followed this idiom in your applications. This restriction is required because without going through the ActionServlet, Struts navigation taglibs (e.g. <html:form> and <html:link>) used in the JSPs will not have the correct sub-app context to work with.
