Spring MVC file upload NullPointerException

Took me hours to figure out and in the end I realized I just had to add this small piece of resolver in my dispatcher-servlet.


    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <!-- one of the properties available; the maximum file size in bytes -->
        <property name="maxUploadSize" value="100000"/>
    </bean>
