spring jaxb exception

Question

hi. my code:

<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"/>
</bean>
<bean id="subscribersXml" class="org.springframework.web.servlet.view.xml.MarshallingView">
    <property name="contentType" value="application/xml"/>
    <property name="marshaller" ref="marshaller"/>
</bean>

<oxm:jaxb2-marshaller id="marshaller">
    <oxm:class-to-be-bound name="myclass"/>
</oxm:jaxb2-marshaller>

I keep getting exception:

java.lang.NoSuchMethodError:
org.springframework.http.MediaType.sortBySpecificity(Ljava/util/List;)V

What is the problem here? whole stack trace:

Answer 1

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>

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)
