添加beans.xml中断输入文件上传

我正在构建一个上传文件的Web应用程序，并试图添加需要使用beans.xml文件的CDI功能。问题是，当我将beans.xml文件添加到web应用程序时，即使在切换到需要beans.xml的任何功能之前，它也会破坏以前的功能性输入文件上传。为什么即使存在一个beans.xml文件来破坏这个功能？添加beans.xml中断输入文件上传

环境和依赖：
JDK 1.7.0_45
NetBeans IDE的7.4补丁2
Windows 7的版本6.1在x86上运行
JavaEE的的Web-API 6.0
primefaces-3.5
战斧-1.1。 14
GlassFish应用服务器4.0

下面的代码是否会有所帮助：

beans.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

GlassFish 4附带JSF 2.2，它已经支持<h:inputFile>的原生文件上传支持。 FacesServlet已经处理上传的文件，然后它击中Tomahawk的<t:inputFileUpload>。

你已经基本上2种选择：

摆脱战斧和使用本地文件上传组件<h:inputFile>代替。

<h:form enctype="multipart/form-data"> 
    <h:inputFile value="#{bean.uploadedFile}" /> 
    ... 
</h:form>

与来自JSF 2.2

import javax.servlet.http.Part; 

// ... 

private Part uploadedFile; // +getter +setter

降级到JSF 2.1或2.0。降级整个服务器是一种方式，尽管有点笨拙。

工作！令人困惑的是，尽管存在明显的JSF /战斧冲突，但我发布的代码实际上是在与我的环境同事合作。因此，我认为这是一个环境问题，但感谢解决问题的核心。 – user3173957

不客气。 – BalusC

我最终切换到了Glassfish Server 3.1.2.2，问题解决了。
