UploadItem contentType via javax.activation

[nimo22]

A UploadItem retrieved via rich:fileUpload has the method "getContentType" which always returns "application/octet-stream".

uploadItem.getContentType() returns "application/octet-stream"

When using explicitly the the "javax.activation-framework" to determine the specified content-type of my uploadItem, I also get "application/octet-stream", which is definitly not true:

String contentType= new MimetypesFileTypeMap().getContentType(uploadItem.getFile().getName());
String contentType2= new MimetypesFileTypeMap().getContentType(i.getFile());

contentType should, in this case, returns "audio/mpeg" and not "application/octet-stream".

How can I determine the specified content-type of my UploadItem ?

I am having the same problem.  I am not using temp files for the upload.  The context type is always application/octet-stream.  Is there a way to get RichFaces to correctly give me the right content type?

Guys, I just made simple check debugged livedemo sample. And see image/jpeg content type for file uploaded. Actually it's right result for the demo. Could you please provide more details(RF version? any other Filters installed?).

Hi Ilya,

I have the following file upload component:

<rich:fileUpload fileUploadListener="#{backingBean.uploadFileListener}" immediate="true" immediateUpload="true" acceptedTypes=""     allowFlash="true" ajaxSingle="true" autoclear="true">

....

</rich:fileUpload>

My RichFaces filter is:

<filter>
        <filter-name>richfaces</filter-name>
        <display-name>RichFaces Filter</display-name>
        <filter-class>org.ajax4jsf.Filter</filter-class>
        <init-param>
            <param-name>maxRequestSize</param-name>
            <param-value>100000000</param-value>
        </init-param>
        <init-param>
            <param-name>createTempFiles</param-name>
            <param-value>false</param-value>
        </init-param>

</filter>

In my backing bean, I have the following:

public void uploadFileListener(UploadEvent event) {

    UploadItem uploadItem = event.getUploadItem();

    ...

}

uploadItem.getContentType() always return application/octet-stream.  In my case, I was uploading Word docs, PDFs, and Windows Media files.

Thanks.

I should also add that I am using Tomcat 5.0.28 and RichFaces 3.3.2 SR1.
