I have tried to declare interceptors in my spring application within my spring.xml configuration file. I am getting the error that:
Line 18 in XML document from ServletContext resource [/WEB-INF/spring/spring.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 18; columnNumber: 16; cvc-complex-type.2.4.a: Invalid content was found starting with element 'interceptors'.
It also doesn't like my annotation-driven tag

Am I declaring my interceptors in the correct configuration file?
You have to declare the namespace for Spring MVC XML elements in the header of your XML file:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
And then use the mvc namespace for the interceptors element:
<mvc:interceptors>
<mvc:interceptor>
<!-- ... -->
</mvc:interceptor>
</mvc:interceptors>
See 17.16 Configuring Spring MVC in the Spring reference documentation for more information.

Controller and project structure:
I am new to Spring Development. I am working on a web application. There are some jsp pages where I need to show some images so I made a resource entry in spring-servlet.xml like this:
<mvc:resources mapping="/schedules/**" location="/schedules/" />
But as I am adding this entry after that my controller classes stop scan and non of my action detecting in says 404. but if am removing above entry from xml than my controllers detected properly. but after removing images urls are not found what am missing.
<context:component-scan base-package="com.spring" />
My recommendation is use latest spring version.
add <mvc:annotation-driven /> in your config files
check the resources folder line <mvc:resources mapping="/schedules/**" location="/schedules/" /> is everything under this folder.
Check the mvc XML namespace is at xmlns:mvc="http://www.springframework.org/schema/mvc" in your Spring servlet-context xml configuration.
The <resources> tag was introduced in Spring 3.0.4, so you need at least that version of Spring and of the xsd.
Thanks To all For your Kind Support. issue is resolved. actually there is a level of hierarchy in which xml tag should declare.
Below code works for me
<context:component-scan base-package="com.spring" />
<mvc:resources mapping="/schedules/**" location="/schedules/" />
<mvc:default-servlet-handler />
<mvc:annotation-driven/>
now my xml is looks like this

Any help would be great! thanks
Your component scan needs to be as below,
<context:component-scan base-package="com.domain.nameOfapp" />
This will scan all the classes under this package including any sub-packages.
Also using #ManagedProperty, are you trying to autowire the spring service bean? I believe you should be using #Autowired.
thymeleaf are new and trying to integrate it in spring mvc 4.
By following this tutorial I ran into this problem:
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.thymeleaf.templateresolver.ServletContextTemplateResolver]for bean with name 'templateResolver' defined in ServletContext resource [/WEB-INF/spring-mvc-config.xml];
Now I'm sure you have all the necessary jars, could depend on what?
attached the configuration file.

the problem was the lack of jar of thymeleaf, I had loaded only to spring mvc 4.
I'm trying to set up Hibernate 4 with Spring 4, and I have run into some problems configuring it. Specifically, in my servlet-context.xml file, I followed a guide and added the following code blocks to this file:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>/WEB-INF/hibernate.cfg.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<tx:annotation-driven />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
Both of these display the following error: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'bean'
The session factory bean also displays this error: Cannot locate BeanDefintionParser for element [bean]
Here is my entire `servlet-context.xml' file (excluding those two code blocks for brevity's sake, though please notice that they are actually in the file):

How can I resolve these issues?
You set the default namespace for that XML file to mvc, so you'll need to prefix your element (beans:bean) or change the default namespace to beans (the usual approach).
Iam working with spring maven hibernate . I have error in adding resources mvc tag in dispatcher servlet file.For adding css and images files i have to add my folders using resources tag for that i have added xmlns mvc and its schema location. But its not working. Below am adding my code. When i remove mvc and resources from it , its working.
Please help.
