Получение исключения «Ресурс ошибки не найден» при использовании скорости

Не могу прикрепить шаблон для отправки письма..

-servlet.xml

<bean id="velocityEngine" 
    class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
        <property name="velocityProperties">
             <value>
              resource.loader=class
              class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
             </value>
        </property>
    </bean>
    <bean id="velocityConfig"
        class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">

        <property name="resourceLoaderPath" value="/"/>

</bean>

    <bean id="velocityviewResolver"
          class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"
          p:prefix="/WEB-INF/velocity/"
          p:suffix=".vm" />
</beans>

код: ошибка указывает на эту строку, которую я использую в своей реализации службы

String text = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "mailtemplate", model);

Я получаю сообщение об ошибке, говорящее о том, что не удается найти какой-либо ресурс
