 javax.servlet.jsp.JspException: Exception creating bean of class app.userselectForm: java.lang.ClassNotFoundException:   

Application is not able to find the class app.userselectForm. Does the file exist in classpath? Is it available in WEB-INF/classes directory?

[Jaidev Arer]

No. Now ran the ant script , but i am getting the screen to enter the field but after entering the field if i press the submit button nothing is happening. not even the error message.
