JSF upload driving me crazy

Question

Hello all,
I've been working with JSF for some months now, and I even made a few 'kinda' working upload implementations. But it never works perfect.
Could anyone please put a working example online. I have only to requirements: I should be able to retrieve the original filename and should be able to upload large (100m+) files.
Thank you very much!!!

If you use MyFaces, you can use this code:
<h:form name="formUpload" enctype="multipart/form-data">
     <h:panelGrid
        id="gridUpload"
        columns="2">
       <f:facet name="header">
            <h:outputText value="Upload do Arquivo de Arrecada��o"/>
       </f:facet>
        <h:outputLabel
           for="uploadFileField"
           value="File:"/>
        <t:inputFileUpload
           id="uploadFileField"
           value="#{uploadBean.file}"
           storage="file" required="true"/>
       <f:facet name="footer">
             <h:commandButton
                id="bottonUpload"
                value="Send"
                action="#{uploadBean.upload}"
                styleClass="BUTTON"/>
       </f:facet>
     </h:panelGrid>
</h:form>
   private UploadedFile file;
   public UploadedFile getFile()
      return file;
   public void setFile(UploadedFile file)
      this.file = file;
   public String upload()
      String fileName = file.getName();
      long fileSize = file.getSize();
      String fileStr;
      try
         fileStr = new String(file.getBytes());
      catch (IOException e)
         String errMsg = e.getMessage();
         FacesContext.getCurrentInstance().addMessage(
               "ERROR",
               new FacesMessage(FacesMessage.SEVERITY_ERROR,
                     "Erro ao carregar arquivo", errMsg));
         return "ok";
   }
