对空文件名的Mime类型警告

Question

有办法消除这些警告吗？file ""是什么意思？我已经在web.xml中添加了下面的内容

00000030 context       W   JSF1091: No mime type could be found for file "".  
To resolve this, add a mime-type mapping to the applications web.xml.

web.xml

<mime-mapping>
    <extension>gif</extension>
    <mime-type>image/gif</mime-type>
</mime-mapping>
<mime-mapping>
    <extension>jpeg</extension>
    <mime-type>image/jpeg</mime-type>
</mime-mapping>
<mime-mapping>
    <extension>jpg</extension>
    <mime-type>image/jpeg</mime-type>
</mime-mapping>
<mime-mapping>
    <extension>png</extension>
    <mime-type>image/png</mime-type>
</mime-mapping>
<mime-mapping> 
     <extension>xml</extension> 
     <mime-type>application/xml</mime-type> 
</mime-mapping>

想必为时已晚，但我最近遇到了同样的问题。

在加载图像的控制器中，必须放置指向其文件名的链接。

即

<p:graphicImage value="#{displayImage.file}" **name="#{image.filename}"** alt="Image Description for #{image.description}" stream="true" title="#{image.copyrightnote}">

希望能帮上忙。干杯干
