Can some one help me with this?
My Controller class looks like this, and i have created the customer model class..
/**
* Handles requests for the application home page.
*/
@Controller
@RequestMapping("/customer")
public class CustomerController {
@RequestMapping(method = RequestMethod.GET)
public ModelAndView student() {
return new ModelAndView("customer", "command", new Customer());
}
@RequestMapping(value = "/addCustomer", method = RequestMethod.POST)
public String addStudent(@ModelAttribute Customer customer,
ModelMap model) {
model.addAttribute("customerName", customer.getCustomerName());
model.addAttribute("emailId", customer.getEmailId());
model.addAttribute("sex", customer.getSex());
return "customerDetails";
}
}

But when I run this application in Tomcat Server.. The first url points to localhost:8080/controller/.
If I append localhost:8080/controller/customer I get the first form page..
But once I click on submit.. it says page not found error.
It's a relative path problem. Your form action is /addCustomer (has / prefix), if you resolve it it's http://localhost:8080/addCustomer. What you wanted is probably http://localhost:8080/appname/customer/addCustomer.
In some cases simply changing it into customer/addCustomer might resolve it, but if your page can also be accessed by http://localhost:8080/appname/customer/ (pay attention to the trailing slash) then this could be a problem. The relative path will translate into http://localhost:8080/appname/customer/customer/addCustomer
Of course now you can think to just do /appname/customer/addCustomer and problem solved, but in fact you are now hard-coding the context path name. If one day the context path changes all this code will break.
One approach I like to use so my JSP can figure out the context path is by defining a root variable
<c:set var="root" value="${pageContext.request.contextPath}"/>
...
<form:form action="${root}/customer/addCustomer">
