JSF : Issues with File Upload using Icefaces component

I am trying to get FileUpload feature working with Icefaces ace:fileEntry but my fileUploadListener on server is not called, here is the code:

xhtml piece:

    <h:form enctype="multipart/form-data">
        <ace:fileEntry id="fileEntryComp"
                       label="File Entry"
                       relativePath="uploaded"
                       fileEntryListener="#{fileUpload.uploadFile}"/>
        <h:commandButton value="Upload File"/>
    </h:form>
</h:body>
</html>

java piece

public void uploadFile(FileEntryEvent event)
    {
        FileEntry fileEntry = (FileEntry) event.getSource();
        FileEntryResults results = fileEntry.getResults();
        for (FileEntryResults.FileInfo fileInfo : results.getFiles())
        {
            if (fileInfo.isSaved())
            {
                log.debug("########### FILE IS SAVED ########");
            }
        }
    }

Now, in current state, i can open file-system navigation popup and i can select file but then fileUploadListener should be hit but right now it does not, also i am able to get some data that i set on server side so server trip is working only issue i have is fileUploadListener is not hit, any suggestions?

Update I am still looking for answer as I have not been able to successfully upload File to the server.

Update 2 Now am getting Content is not allowed in prolog exception, not sure what exactly that means, here is the stacktrace:

    ERROR [Faces Servlet]  - Servlet.service() for servlet Faces Servlet threw exception: javax.faces.view.facelets.Facele
tException: Error Parsing /trade_entry/UploadBlotter.xhtml: Error Traced[line: 2] Content is not allowed in prolog.

I don't see any <h:form> surrounding your component, is there any in your code? I don't have any experience with icefaces but I'm using to richFaces. With a

<rich:fileUpload immediate="true" id="fileUploadId" 
                        ajaxSingle="true" listHeight="70px" listWidth="500px"
                        uploadButtonClass="otherButton" styleClass="backgroundColorInput"
                        addButtonClass="otherButton"
                        fileUploadListener="#{paramActions.fileUploadListener}">
                        <a:support event="onuploadcomplete" reRender="paramsForm" />
                    </rich:fileUpload>

it needs to be enclosed in a

<h:form id="paramsForm" enctype="multipart/form-data">

multipart/form-data enctype is needed for fileUpload

Most of the time unclosed tags causes that exception. Check you xhtml, you might locate any tag which open.

e.g : Any open div or span..

remove the enctype="multipart/form-data" from the h:form it should work fine without it.

I had exactly this problem on a JBoss 7.1 server. I had an EAR project, some EJB projects and a couple of WAR projects. When I had the problem I deployed the icefaces jars in the EAR library, but when I moved them to the WAR project that used ace:fileentry it started to work.
