Spring not dinfing dispatchServlet

I am new to spring. And I have encounter an error on my spring application. It says :
GRAVE: Servlet [dispatcher] in web application [/web-customer-function] threw load() exception
java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1309)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1137)
at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:546)
I have beean dealing with this for a long time now... It has been 5 days. And this is what I have done...
Deployment Asssembly > Add lib folder to path
Stop,clean or/and delete server
Rewrite entire code
Download the org.springframework.web.servlet.DispatcherServlet and try to run again.
I would appreciate the help to all if possible.

I got the problem fixed...
Thank you all for the help it made my think again. So I refactor the code from zero checked the libraries and it ran smoothly. So the issue was with the libraries because after refactoring the code it did not work. But checking the libraries it worked.

Trouble with hibernate and spring xml configuration

Hello guys i have been playing around with spring mvc and hibernate. But now i am getting an error when trying to connect both hibernate and spring with XML configuration. I get this error below:
03-Nov-2015 22:22:19.675 WARNING [RMI TCP Connection(2)-127.0.0.1] org.springframework.web.context.support.XmlWebApplicationContext.refresh Exception encountered during context initialization - cancelling refresh attempt

I created my webapp folder in src/main. in my webapp folder i created WEB-INF folder. And WEB-INF folder contained files: service.xml, dispatcher-servlet.xml. Now for my hibernate.cfg.xml, it was placed in src/main folder structure. But when i try to add it in the service.xml upon loading the dispatcher, my hibernate.cfg.xml seems not to be found. Does anyone know why? This is where i am having trouble:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

I can't seem to find the value of configLocation. Has anyone encountered this issue.

I fixed my error by placing hibernate.cfg.xmlin the root directory of WEB-INF. That is placed in webapp folder and solved my issue.

you have already defined "DataSource" bean, I guess you don't need to configLocation property.
you can refer below link for more options http://www.mkyong.com/spring/maven-spring-hibernate-mysql-example

And mine controller:

logger.info("Device is "+device);
if(device.isNormal()){
return "hello";
}
return "index";
}
}
Mine webapp folder look like this:
WEB-INF---
|
pages---
|
mobile---
|
index.html
So, the redirecting work just fine,I'm getting redirected to mobile version. But page i'm redirected to is non existing(404). I' just can't see the error. Thank you in advance.

"rotate" the redirect to url to sitename:8080/studentacc/m" because it is likely that "studentacc" is the name of your application in the application server, and therefore it must be the first part.
From a very short look to the API, I would try to use the SiteSwitcherHandlerInterceptor.urlPath(String mobilePath, String rootPath) method with the additional parameter for the rootPath
<bean class="org.springframework.mobile.device.switcher.SiteSwitcherHandlerInterceptor" factory-method="urlPath">
<constructor-arg value="/m" />
<constructor-arg value="/studentacc" />
</bean>

Someone can help me??

If you want to open page with name "index.jsp": add following line in your configuration (you must have index.jsp file in /WEB-INF/jsp):
<mvc:view-controller path="/" view-name="index" />
If you want to add some objects to your page you must write simple class, annotate it with #Controller annotation and add methods with mappings:
#Controller
public class IndexController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public String showRegistration(Model model) {
Integer usersCount = 1; // replace with service code
model.addAttribute("usersCount", usersCount);
return "index";
}
}

Spring data not saving dates

I have an Spring project with one simple entity and a JPA repository. The entity has three variables: Name (String), active (boolean) and date (java.util.Date). Once deployed, Hibernate creates the table in my MySQL database using varchar, tinyint and datetime. All seems correct but when I create/modify an instance of the entity and call the save() method of the repository, all fields are saved except the date. Is there any know problem storing dates with a JPA repository or meaby I'm doing something wrong?
I'm not putting any code here because is only a simple class and an interface for the repository. Also, the entity is being saved. My problem is only related with Date field (and any other Date field that I could define). Having said this, if anything is needed, just ask.
