我目前正在ICEfaces论坛上解决我的问题 – 遗憾的是,现在没有一个提供的选项导致了解决方案,但是他们确实让我对整个JSF主题有了更多的了解(相关信用归功于BalusC,经常:-)).
我会尽量保持这个线程的最新状态并发布一个答案,如果问题最终得到解决,以帮助其他可能遇到它的人.
到目前为止我的发现是：
>需要禁用Seam Multipart Filter,因为它会阻止fileEntry组件正常工作
>我的应用程序中仍然存在一些讨厌的库问题导致(无声)ClassLoading-问题：存在2个icefaces-ace.jar文件,一个在EAR / lib中,一个在EAR / WAR / WEB-INF / lib中.从WEB-INF中删除该组件会导致组件无效,从EAR / lib中删除该组件导致我的应用程序不再部署.
将所有前端jar(icefaces.jar,icefaces-ace.jar,icefaces-compat.jar)从EAR / lib移动到WEB-INF / lib时,我收到了我的EAR jar部分的各种ClassNotFoundExceptions：ValueChangeEvent,RowSelectorEvent等无法找到(这意味着,所有这些事件都从视图进入后端).例：

整个故事
我正在使用Seam 2.3和ICEfaces 3.1.0开发Web应用程序.这意味着,正在使用JSF2.
我的应用程序作为EAR部署在JBoss AS 7.1.0上,包含应用程序逻辑的JAR和所有视图相关内容的WAR.
我最近从Seam 2.1.2迁移到Seam 2.3和ICEfaces 1.8.2到3.1.0.这一步很糟糕,但现在一切正常,抛开一些小问题.
唯一的大问题是,当我使用组件上传文件时,无论我使用Seam组件还是ICEfaces组件 – 在Seam中,上传的文件始终为null,而在ICEfaces中,我的fileEntryListener-Method永远不会被调用.
使用ICEfaces：
在2.X之前的ICEfaces版本中,有一些ice：inputFile-component,它已被2.X删除并替换为ace：fileEntry.
InputFile运行良好,但FileEntry没有.我的问题与描述完全相同
JSF : Issues with File Upload using Icefaces component – 永远不会调用fileEntryListener.我尝试了那里的建议(在周围的表单上使用enctype =“multipart / form-data”,使用h：commandButton进行表单提交),但它不起作用.提供的唯一解决方案是切换到Richfaces,这对我来说不是一个选择.
使用Seam：
很高兴,Seam拥有自己的内置fileUpload-component,s：fileUpload.
它也不起作用,但至少向我展示了一个可以进一步观察的地方.在调试这个组件的doDecode-Methods时,我发现我的请求不是MultipartRequest.疯狂的事！用于上载文件的所有表单都将enctype声明为multipart / form-data.我想,当我尝试使用ICEfaces组件时,也会发生同样的情况 – 没有多部分请求,导致没有调用侦听器.
那么：我如何让它发挥作用？什么是没有Request作为MultipartRequest进入？我是否想念web / components.xml中的内容？
web.xml中：

JSF映射到Seam组件,fileData为byte [],fileName和contentType为String. fileEntryListener映射到void方法,该方法将FileEntryEvent作为输入.
更新
为了让你及时了解我的发现到目前为止：
考虑到BalusC的答案,我更深入地研究了过滤器的内容.我已经尝试添加/删除Seam Multipart Filter,但现在我发现当我在components.xml中添加它并通过显式禁用它时
<web:multipart-filter disabled="true"/>
ICEfaces至少发生了一些事情：FileEntryPhaseListener抛出了异常,这是以前从未发生的事情：

至少这是值得关注的.如果我使用fileEntryListener之类的
fileEntryListener="#{uploadBean.fileUploadListener}"
抛出上面的异常,如果我使用：
fileEntryListener="#{uploadBean.fileUploadListener()}"
它抱怨该方法需要参数,如果我使用它,如：
fileEntryListener="#{uploadBean.fileUploadListener(null)}"
没有抛出异常,但由于事件为null,没有文件到达我的UploadBean.闻起来像一些图书馆问题,但至少还有别的东西要看.
上传bean
这里没有太多发生,它只是：
@Stateful
@Name("uploadBean")
@Scope(ScopeType.SESSION)
@JndiName(value = "java:app/myApp.jar/UploadBean")
public class UploadBean implements IUploadBean
{
public void fileUploadListener(FileEntryEvent event)
{
System.out.println("listener called!");
}
}
监听器也在bean的接口中声明.
最佳答案 首先是一些技术背景信息：直到即将推出的JSF 2.2,JSF本身不支持multipart / form-data请求.因此,提供文件上载组件的组件库必须提供自定义过滤器本身.这应该正确解析multipart / form-data请求,并将所有必要的常规数据存储在HTTP请求参数映射中,并将上载的文件存储为请求属性.这样,JSF可以通常的方式继续使用request.getParameter()获取常规数据,组件库本身可以将上传的文件作为请求属性获取.
如果是Seam的< s：fileUpload>,则需要org.jboss.seam.web.MultipartFilter来执行multipart / form-data解析作业.我从未使用过Seam(也不是ICEfaces),但Google告诉我你在webapp的web.xml中基本上需要这个
<filter>
<filter-name>Seam Multipart Filter</filter-name>
<filter-class>org.jboss.seam.web.MultipartFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Seam Multipart Filter</filter-name>
<url-pattern>*.seam</url-pattern>
</filter-mapping>
或者这在Seam components.xml中：
<web:multipart-filter url-pattern="*.seam" />
ICEfaces组件必须配置类似的Filter. ICEfaces 3.x文档缺乏(或者我的Google / icefaces.com搜索技能不好),所以我不能详细说明这一点.
重要的是要记住,HTTP请求只能被解析一次(客户端只发送一次,而不是多次),因此你不能在同一个请求上同时使用这两个multipart / form-data解析器.在第一个之后开始的那个将获得一个空的请求主体,这个主体不能解析为任何合理的东西.因此,如果您正在使用使用后一个过滤器的组件,那么您将无法获得模型中的任何内容.确保您没有偶然或通过实验配置两者.
