无法启动Tomcat

我在Tomcat 8上运行的Eclipse中创建了Vaadin 7项目。我想在我的应用程序中使用EJB，CDI和JPA。这是我的Ivy.xml。无法启动Tomcat

<dependency org="org.eclipse.persistence" name="javax.persistence" rev="latest.release"/> 
    <dependency org="com.vaadin" name="vaadin-cdi" rev="latest.release"/> 
    <dependency org="javax.inject" name="javax.inject" rev="latest.release"/> 
    <dependency org="javax.ejb" name="ejb-api" rev="latest.release"/>

但是当我启动Tomcat时，我得到了下面的错误。你知道为什么找不到那个班吗？

它缺少一个提供javax.enterprise.inject.spi.BeanManager类的JAR .... –

平原tomcat的只是一个servlet容器，所以没有进入春天的世界它只是为了微不足道的应用程序（没有JPA，CDI，EBJs ...）的良好基础。如果你想从Java EE 7获得最新的东西，你应该看看TomEE如果你喜欢Tomcat或者Wildly。
