Error in uploading content of file int internal table

Question

I want to upload one file.Store the content into internall table.  i ahve written the the following code under input processing.
event handler for checking and processing user input and
for defining navigation
file upload and echo
    data: entity         type ref to if_http_entity,
          file           type xstring,
          content_type   type string,
          LV_DELIMITER   type string VALUE '##',
          content_length        type string,
          num_multiparts type i,
          i              type i value 1,
          doEcho         type string value 'xyz',
          value          type string,
          conv   TYPE REF TO CL_ABAP_CONV_IN_CE,
          LV_DELIMITER1   type string VALUE ',',
          content1 type string value '22##11##35',
          content TYPE STRING.
    DATA: BEGIN OF t_temp,
          str(10) TYPE c,
    END OF t_temp.
    data : ty_temp type standard table of t_temp,
           wa_temp like line of ty_temp.
  find multipart containing file
    num_multiparts = request->num_multiparts( ).
    while i <= num_multiparts.
      entity = request->get_multipart( i ).
      value = entity->get_header_field( '~content_filename' ).
      if not value is initial.
      found a file!
        navigation->set_parameter( name  = 'content_filename'
                                   value = value ).
        content_type = entity->get_header_field( 'Content-Type' ).
        navigation->set_parameter( name  = 'content_type'
            value = content_type ).
      get file content
        __file = entity->get_data( ).__
        __conv = CL_ABAP_CONV_IN_CE=>CREATE( input = file ).__
        __conv->READ( importing data = content ).__
        __replace LV_DELIMITER with LV_DELIMITER1 into content1.__
        __SPLIT content AT LV_DELIMITER1 INTO TABLE Ty_temp.__
      get file size
        content_length = xstrlen( file ).
        navigation->set_parameter( name  = 'content_length'
            value = content_length ).
      echo/download the same file again?
       doEcho = request->get_form_field( 'doEcho' ).
        if doEcho is not initial.
        set response data to be the file content
          runtime->server->response->set_data( file ).
        set the mime-type and file size in the response
          runtime->server->response->set_header_field(
            name  = 'Content-Type'
            value = content_type ).
          runtime->server->response->set_header_field(
            name  = 'Content-Length'
            value = content_length ).
          runtime->server->response->delete_header_field(
            name = 'Cache-Control' ).
          runtime->server->response->delete_header_field(
            name = 'Expires' ).
        endif.
        exit.
      endif.
      i = i + 1.
    endwhile.
    if doEcho is not initial.
      signal to the BSP runtime that the response data is
      complete and no onLayout method should be called to
      create the response
      navigation->response_complete( ).
    else.
      navigation->goto_page( 'transition_parameter_upload.htm' ).
    endif.
