無法在JBoss AS 7.1.1中注入EntityManager

在JBoss AS 7.1.1上部署我的應用程序時，EntityManager注入存在問題。應用程序使用Struts2和Struts2 CDI插件。除了EntityManager注入CDI工作正常 - 只有EntityManager不注入。這個錯誤是特定於JBoss的 - 在GlassFish 3.1.2.2 Web Profile下，相同的應用程序沒有錯誤。應用程序打包爲war，分離的core-0.2.jar（應用程序邏輯）位於WEB-INF/lib文件夾中。我不使用Spring等無法在JBoss AS 7.1.1中注入EntityManager

嘗試使用Hibernate作爲JBoss AS 7的模塊。

創建/modules/org/hibernate/3/module.xml

module.xml

<module xmlns="urn:jboss:module:1.0" name="org.hibernate" slot="3"> 
    <resources> 
     <resource-root path="hibernate-core-3.6.1.Final.jar"></resource-root> 
     <resource-root path="hibernate-entitymanager-3.6.1.Final.jar"></resource-root> 
     <resource-root path="hibernate-commons-annotations-3.2.0.Final.jar"></resource-root> 
     <resource-root path="asm-3.3.jar"></resource-root> 
     <resource-root path="antlr-3.2.jar"></resource-root> 
     <resource-root path="btm-1.3.3.jar"></resource-root> 
    </resources> 
    <dependencies> 
     <module name="org.jboss.as.jpa.hibernate" slot="3"></module> 
     <module name="javax.api"></module> 
     <module name="javax.persistence.api"></module> 
     <module name="javax.transaction.api"></module> 
     <module name="javax.validation.api"></module> 
     <module name="org.antlr"></module> 
     <module name="org.apache.ant"></module> 
     <module name="org.apache.commons.collections"></module> 
     <module name="org.dom4j"></module> 
     <module name="org.infinispan"></module> 
     <module name="org.javassist"></module> 
     <module name="org.jboss.logging"></module> 
     <module name="org.slf4j"></module>
