You are using a Microsoft SQL Server driver and MySQL dialect.
Use org.hibernate.dialect.SQLServerDialect for Microsoft SQL Server.

Dispatcher-Servlet.xml Cannot find class [org.springframework.web.servlet.mvc.support] for bean with name

I have been trying to implement the FullCalendar plugin and when I run the program through Apache Tomcat I get this error:

I presume I am missing some code here but I am not sure what is missing and why the error is displaying.

The exception says it cannot find the Class org.springframework.web.servlet.mvc.support which comes under Web Servlet Jar :
<dependency>
<groupId>org.springframework</groupId>
<artifactId>org.springframework.web.servlet</artifactId>
<version>x.x.x</version>
</dependency>
Can you check if you have/need a one ?

Spring MVC with JPA: Not able to instantiate JpaRepository from a jar

I am trying to import a standard spring project P1 into a web project P2 and I am implementing the web aspect of P1 in P2.
I have imported all resources of P1 in P2 as P1.jar
Have explicitly imported the application context file as well using <import-resource> which happens successfully.
But the JpaRepositories does not get autowired in P2. It doesn't seem to be in the context of P2.
Can anyone suggest what I might be missing here.

UPDATE: 28Nov2016
Upon including <jpa:repositories base-package> configuration in P2's application context, I no longer get the wierd error which I was getting earlier.
Also, enabling a successful import of xml config in Spring bean support, everything else is falling appropriately into place. Only the JpaRepositories referred in P1 are not reflecting in P2's context.

I dont think what you are trying to do is possible. You need to enable repository scan in your p2 and mention the packages in that scan.
If your p1.jar is in the classpath of p2 then you only have enable repository scan in your p2,
<jpa:repositories base-package="com.home.p1.blog.repo" />

RESOLVED: Please note that to import the JpaRepositories from P1.jar in P2, we don't have to mention <jpa:repositories> tag in P2's config xml.
Just ensure that we are appropriately importing the P1's config.xml.
Also Eclipse users need to add Xml / Java config in Spring Beans Support tab as well as enable support for import element.

Hibernate not creating tables with HSQL and Spring

anybody has idea why hibernate is not creating tables in my example ?
Here's my web.xml - http://pastebin.com/ZaseSaBS
mvc-dispatcher-servlet.xml - http://pastebin.com/LbdxMSAb
applicationContext.xml - http://pastebin.com/bAHMaVNX
console logs - http://pastebin.com/tTZZbxkX
I have similiar project with almost the same configuration and everything seems to run just fine on the other project. Any ideas why it's not creating tables here?
I've one test enity in com.calculator.enity with #Entity #GeneratedValue annotations, i have it listed in persistence.xml file. There's also JpaRepository for this entity in com.calculator.repository

It looks like your persistence configuration is not properly done. Use this sample persistence configuration as per your requirement. This is working fine for me.

HTTP Status 500 - Servlet.init() for servlet spring threw exception. Error creating bean with name 'sessionFactory' defined in ServletContext resource

I think this error has been asked here. Although questions have been answered, but I still do not know what to do. "I cloned repo của in an IDE and deployed to Tomcat" and "cloned your repo on the commandline and ran a Maven build, the produced WAR file is fine" I have searched on the net a lot but still do not understand what i need to do .
my error:
