and i have Login.java. which is just a pojo with username,password getters and setters
the problem is like when i use <spring:bind path="login.username"> in the jsp page. I am getting 404 error. I am not able to figure out wht the problem is. I tried googling and reading some articles etc. But couldnt solve it. Please if some one can guide me to solve this.. i would be thankful.
the error i am getting in the tomcat console there is also an error regarding the log4j but i think for time being we can ignore it. But the main problem is the 404 error in my loginpage of the application.
