redirect all jsp to login page only

[Sharad Raj]

I have created a Web Application using struts 1.0, written almost 8 jsp. The problem is after starting application, when I change URL and provide /somejsp.jsp, instead of my start jsp it will lead to somejsp.jsp file, which is not required. I do not want to keep my jsp inside WEB-INF. Is there any way to modify application so that whenever user changes URL, it will lead to login page only, instead of /somejsp.jsp

Put a filter or interceptor on.

If the user is not logged in, redirect them to the login.

If they are logged in, and somejsp.jsp does not exist you could built a customer error page.

I assume that when you say "user changes URL", you mean that the user is going to the browser's address bar and modifying the URL visible there, right?

Well, the server has no way of knowing how the URL of a request was generated. Whether it was generated by the user clicking on a link or by the user typing in the address bar, the server can't tell.

We can be access them directly. Refer the following thread JSP's should Inside WEB-INF

Hi William,

Yes, we can use interceptors or filters. Could you send me code please? Do I need to put code in web.xml and create a separate class?

Not sure if this is what you want?

Add this at the Struts-config.xml:

<controller processorClass="com.ABCProcessor"/>

And your class file, it should be something below:

public class ABCProcessor extends RequestProcessor {

    protected boolean processPreprocess(HttpServletRequest request, HttpServletResponse response) {
        HttpSession session = request.getSession();
        
        try {
            User user = (User)session.getAttribute("user");
			
			if(user!=null){
				//user is logged on
			}else{
                                //user not logged on
				response.sendRedirect("somejsp.jsp");
				return false;
			}

        } catch (Exception e) {
            
        }
        return true;
    }
}
