Re: Re: Re: [Tomahawk] NullPointer Exception during File-Upload

Hi sorry forgot to put the new html code inside.
Here it is:
     <h:form id="upload" enctype="multipart/form-data">

                           <t:inputFileUpload
                                   id="myUploadedFile"
                                   storage="file"
                                   accept="image/*"
                                   styleClass="myStyle"
                                   value="#{home.uploadFile}"/>

                           <h:commandButton 
actionListener="#{home.upload}"/>

                           </h:form>

Hi Wolfgang,

make sure that the surrounding h:form has enctype="multipart/form-data".

cheers,

    Hi,

    I tried to upload a File but I always got a NullPointerException,
    because the uploadFile.getBytes(), uploadFile.getContentType() and
    uploadFile.getName()) are null.

    I don't understand why?!

    Cheers!


    private UploadedFile uploadFile;


    public void upload(ActionEvent evt) throws IOException
        {
            FacesContext facesContext = FacesContext.getCurrentInstance();

    facesContext.getExternalContext
    ().getApplicationMap().put("fileupload_bytes",
    uploadFile.getBytes());

    facesContext.getExternalContext().getApplicationMap().put("fileupload_type",
    uploadFile.getContentType());

    facesContext.getExternalContext
    ().getApplicationMap().put("fileupload_name",
    uploadFile.getName());

        }

    // Getter and Setters

        public UploadedFile getUploadFile() {
            return uploadFile;

            this.uploadFile = uploadFile;
        }
