Java controller giving 404 error on live server

I m setting up my java web application on the server but the rest controller is giving 404 error.
All is working fine on my local system.
This is my 1st project in java hibernate spring.

The main issue i have is, it is able to run index.jsp but not the controller. What can be the issue?
Please guide me in right direction.
Thanks

you can not open that url in browser because it is POST service, you can only open GET url in browser. you need to add a body while hitting that url to test
your service you can use postman.

no need to send "Accept" header this way, you can use however following attribute instead if you expect a json body with the post request :
#RequestMapping(value = "/user/login", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE);
if you want to get "Accept" header value of your request you can get it like :
public Map login(#RequestBody User parameters,#RequestHeader(value="Accept") String accept){

Spring Exception Handling : org.springframework.beans.factory.CannotLoadBeanClassException

I am getting error :
java.lang.ClassNotFoundException:
org.springframework.web.servlet.handler.SimpleMappingExceptionResolver
I am hitting URL : http://localhost:8080/SpringMvcExceptionHandling/student on my local machine
Full Strack Trace is :
I have already checked most of the question/answer but not getting any help to resolve my issue,Please help.
Here is what I have done :
I am working on Spring Exception Handling with Jars(Spring-3.1.2). I am not using maven.

SpringException.java
package com.exceptionhandling.mvc.controller;

}
public String getExceptionMsg() {
return exceptionMsg;
}
public void setExceptionMsg(String exceptionMsg) {
this.exceptionMsg = exceptionMsg;
}
}
My Project Structure Looks Like
Jars
Added Two External Jars :

In your SpringMvcExceptionHandling-servlet.xml file, your bean class name must be fully qualified (with no spaces in between).
So your solution must be:
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">

Invocation of init method failed; 'sessionFactory' or 'hibernateTemplate' is required

I am getting the error as in the question. My Dao Implement Class is as follows :

Thank you. (Excuse me if you have any programming error severe But I am learning)

Since you are using CDI you should initialize your stuff in a method that is annotated with #PostConstruct
so you could replace the constructor in testeHibernate.java with
#PostConstruct
public void init() {
utdao = new UtilizadorDAOimpl();
utiliza = new Utilizador();
}
There is also an annotation for when a class is teared down in CDI, which is #PreDestroy
Also it might come in handy to stick to coding conventions and name the files equally to your class name using a capital letter at the beginning.

Unable to apply aspect in spring MVC

In my project i want to apply AOP in Spring MVC . and show the output in webpage .but unable to show and unable apply advice in the controller class.

#Aspect

/** Following is the definition for a pointcut to select
* all the methods available. So advice will be called
* for all the methods.
*/

* before a selected method execution.
*/

System.out.println("Going to setup student profile.");
}
/**
* This is the method which I would like to execute
* after a selected method execution.
*/
#After("selectAll()")
public void afterAdvice(){
System.out.println("Student profile has been setup.");
}
/**

* when any method returns.
*/
#AfterReturning(pointcut = "selectAll()", returning="retVal")
public void afterReturningAdvice(Object retVal){
System.out.println("Returning:" + retVal.toString() );
}
/**
* This is the method which I would like to execute
* if there is an exception raised by any method.
*/
#AfterThrowing(pointcut = "selectAll()", throwing = "ex")
public void AfterThrowingAdvice(IllegalArgumentException ex){
System.out.println("There has been an exception: " + ex.toString());

I agree with M.Deinum, please correct these notes first of all. Further you should delete your Dispatcher-servlet.xml because you have a FileSystemXmlApplicationContext and have defined all of your beans in xml loaded there. Then please delete <listener> and <context-param> elements in web.xml and configure your aspect like this:
<aop:aspectj-autoproxy />
<!-- Aspect -->
<bean id="loggingAspect" class="Logging" />
