Converting Resource(Dictionary Simple Type) to Binary Format.

Question

Hello Experts,
In my Web Dynpro Application,
I have a View Context attribute called "FileResource" of type Resource(Dictionary Simple Type) which is bound to the FileUpload UIElement of View.
When im running the application I am able to Upload the file in my view context attribute successfully,
Now I need to pass it to the RFC as an Import Parameter which is declared as type "RAW-Uninterpreted Sequence of bytes",
kindly guide me how to convert the value of the view context attribute "FileResource" of type Resource(Dictionary Simple Type) into BINARY format, so that i can pass it to the RFC as an import parameter.
Thank you please reply.........

I used this code from a tutorial.  And it work.  Place Some of this code on any button.
     IPrivateFileUploadVIEW.IContextElement element = wdContext.currentContextElement();
     //if a file in the FileUpload field exists
     if (element.getResource() != null)
          IWDResource resource = element.getResource();
          try{
               InputStream archivo = resource.read(false);
               byte[] b = new byte[5000];
               archivo.read(b);
               //ResourceBundle.getBundle();
               wdContext.currentZ_Lmmfu_Cambio_Estado_InputElement().setI_Archivo(b);
               wdThis.wdGetAdminCMPController().executeZ_Lmmfu_Cambio_Estado_Input();
               //Imprimir nombre del archivo     
               String name=resource.getResourceName();
               wdComponentAPI.getMessageManager().reportException(name,false);
                    File f = new File(resource.toString());
     catch(IOException error)
          wdComponentAPI.getMessageManager().reportException(error.toString(),false);
      //report success message
     // wdComponentAPI.getMessageManager().reportMessage(IMessageAdministracionCMP aa ,new Object[] { resource.getResourceName()}, false);
      else
     // if no file in the FileUpload field exists
     //     report error message
     wdComponentAPI.getMessageManager().reportException("Search for a file",false);
     //     clear the 'FileResource' context value attribute
     element.setResource(null);
Is there a better way to do this.
I need to get the creation or modification date from the original file.  How can I do this?
