Puedes usar filtro.
@Override
public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
HttpServletRequest test1= (HttpServletRequest) arg0;
test1.getRequestURL()); it gives http://localhost:8081/applicationName/menu/index.action
test1.getRequestURI()); it gives applicationName/menu/index.action
String pathname = test1.getServletPath()); it gives //menu/index.action
if(pathname.equals("//menu/index.action")){
arg2.doFilter(arg0, arg1); // call to urs servlet or frameowrk managed controller method
// in resposne
HttpServletResponse httpResp = (HttpServletResponse) arg1;
RequestDispatcher rd = arg0.getRequestDispatcher("another.jsp");
rd.forward(arg0, arg1);
}
no se olvide de poner <dispatcher>FORWARD</dispatcher>
en el mapeo de filtro en web.xml
