Even though you keep your spring-common.xml in your project. Your container (Tomcat, Jboss) will identify them if they are accessible to them. Seems that's not accessible to the containers.
It can be done in 2 ways.
1) Include your spring-common,xml to the web.xml's context config location as follows
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springMVC-servlet.xml</param-value>
<param-value>classpath:spring/spring-common.xml</param-value>
</init-param>
2) Import the sprin-common.xml from springMVC-servlet.xml
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="order" value="2" />
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".html" />
</bean>
<import resource="spring-common.xml"/>
