+ <section><title>How Do I Ensure that JSP Pages are Accessible Only
Through the Controller Class?</title>
+ <p>To prevent users from navigating directly to a JSP
+page, register the following filter class. The filter class will intercept
direct requests for JSP pages
+and redirect the user to the Controller class in the JSP's parent directory.
</p>
+<source>package example;
+
+import java.io.IOException;
+import javax.servlet.*;
+import javax.servlet.http.*;
+
+public class JspToPageFlowFilter implements Filter
+{
+ public void doFilter( ServletRequest request, ServletResponse response,
FilterChain chain )
+ throws IOException, ServletException
+ {
+ // Redirect to the begin method in the parent directory
+ String pagePath = ( ( HttpServletRequest ) request ).getContextPath()
+ ( ( HttpServletRequest ) request ).getServletPath();
+ int lastSlash = pagePath.lastIndexOf( '/' );
+ String parentDir = pagePath.substring( 0, lastSlash + 1 );
+ String beginAction = parentDir + "begin.do";
+ ( ( HttpServletResponse ) response ).sendRedirect( beginAction );
+ }
+
+ public void init( FilterConfig filterConfig )
+ throws ServletException
+ {
+ }
+
+ public void destroy()
+ {
+ }
+}</source>
+<p>Register the class in <code>WEB-INF/web.xml</code> as shown below:</p>
+<source> <filter>
+ <filter-name>JspToPageFlowFilter</filter-name>
+ <filter-class>example.JspToPageFlowFilter</filter-class>
+ </filter>
+
+ <filter-mapping>
+ <filter-name>JspToPageFlowFilter</filter-name>
+ <url-pattern>*.jsp</url-pattern>
+ <dispatcher>REQUEST</dispatcher>
+ </filter-mapping></source>
