I downloaded the FileUpload component by BalusC from http://dominikdorn.com/?p=169 . This is how I would like to use it - with Primefaces:

Code: Select all

    <h:form id="uploadForm" enctype="multipart/form-data">
        <hh:inputFile id="uploadedFile" value="#{adcUploadBean.uploadFile}"/><br />
        <p:commandButton value="Upload" image="icon-upload" action="#{adcUploadBean.handleFileUpload}" update="detailsPanel"/>
    </h:form>
But when I press the Upload button I get:

    WARNING: org.apache.catalina.connector.RequestFacade cannot be cast to net.balusc.http.multipart.MultipartRequest

    java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to net.balusc.http.multipart.MultipartRequest

            at net.balusc.jsf.renderer.html.FileRenderer.decode(FileRenderer.java:88)

It works if ajax="false" is added (also with h:commandButton):

Code: Select all
    <h:form id="uploadForm" enctype="multipart/form-data">
        <hh:inputFile id="uploadedFile" value="#{adcUploadBean.uploadFile}"/><br />
        <h:commandButton value="Upload" action="#{adcUploadBean.handleFileUpload}" />
    </h:form>
Checking with Firebug it reveals the issue, in the non-ajax case the pure form-data is sent:

Parts multipart/form-data

uploadForm	uploadForm

but with ajax, the form data is missing:

uploadForm=uploadForm&javax.faces.ViewState=6233438609002960529%3A65139178333663670&primefacesPartialRequest=true&uploadForm:j_idt59=uploadForm:j_idt59&primefacesPartialUpdate=detailsPanel
I found no way of telling p:commandButton what to send.

It would be really nice if this could be made to work, until the official fileUpload component is fixed.
			Code: Select all
Servlet 3.0 is no problem since we need the full Java EE 6 stack anyway (JPA 2.0, EJB 3.1 etc)...
Cool!
