Problems when splitting up applicationContext to multiple file for portlets - configuration

Question

I have a plugin project containing two portlets. For each portlet I defined its own applicatioContext file which works well but I have to put some definitions in each applicationContext.xml redundantly which I want to avoid.
I'd prefer to put this code
<bean class="org.springframework.web.portlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
<property name="order" value="1" />
</bean>
into a parent applicationContext.xml which holds definitions for all portlets and only the specific configurations into the portlet specific applicationContext.xml s.
But this doesn't work. If I don't define the jspResolver in each applicationContext.xml it can't be found resulting in an error.
In my portlet.xml I have defined this init-param for each portlet:
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/spring-mvc-portlet.xml
/WEB-INF/first-portlet.xml</value>
</init-param>
...
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/spring-mvc-portlet.xml
/WEB-INF/second-portlet.xml</value>
</init-param>
whereby spring-mvc-portlet.xml holds the definitions used from all portlets.
The web.xml:
<?xml version="1.0" encoding="UTF-8"?>

I think you are half way through.
Try to put yoour spring-mvc-portlet.xml into web.xml file like this:
<web-app ...>
...
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/path/to/your/spring-mvc-portlet.xml</param-value>
</context-param>
...
</web-app>
It serves as definition of common portlet application context. Then put following lines into portlet.xml:
<portlet>
...
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/path/to/your/first-portlet.xml</value>
</init-param>
...
</portlet>
<portlet>
...
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/path/to/your/second-portlet.xml</value>
</init-param>
...
</portlet>
It works for me, so I hope it helps you...
