Answer 1

This is a sign of library version mismatch. You should either upgrade spring, or upgrade the other library that is replying on it. (Or possibly downgrade any of them)

Answer 2

Do you mean to include a BeanNameViewResolver in your the viewResolvers list? Alternatively, put it in the defaultViews list. I can't tell exactly how you want the view resolution to occur.
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="xml" value="#{subscribersXml.contentType}" />
</map>
</property>
<property name="order" value="0"/>
<property name="viewResolvers">
<list>
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
</list>
</property>
</bean>
