JavaEE6 CDI的问题
最近接手一个JavaEE6 的项目以前从来没搞过这东西，使用的IED netbeans 服务器glassfish有几个问题想问下
项目部署的时候出这个错误：

看了下 主要是这个类中 @inject 一个inte易做图ce的dao，我现在找不到这个实现类在哪里，是不是这个实现类的问题
项目当中使用glassfish配置的数据源，持久性文件persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="dldwbase" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>jdbc/vbp</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
</properties>
</persistence-unit>
</persistence>
另外这个persistence.xml到底应该在什么位置，我这个项目现在有2个 一个在web-inf下 一个在src的conf，META-INF下面
还有谁能给我讲下，这个@inject的原理，是指这个J2EE6的容器自动寻找注入类的构造方法，然后在注入的吗，如果我注入的是一个inte易做图ce类型的，那他会自动寻找这个inte易做图ce的实现类吗？容器怎么知道我这个借口的实现类在哪，好多问题希望大神给解答下，谢谢 javaee glassfish CDI @inject netbeans
补充：Java , Web 开发
