更新Oracle db中的BLOB数据时的java.sql.SQLException

Question

我正在尝试使用hibernate中的Session.doWork()更新我的数据库中的BLOB列：

PreparedStatement pStmt = null;
ResultSet rs = null;
  try {
    String sql = 
      " SELECT " + "ITEM_IMAGE" + 
      " FROM " + "ITEM_IMAGES" + 
      " WHERE " + "ITEM_CODE" + " = ? " +
      " FOR UPDATE";
    pStmt = con.prepareStatement(sql,ResultSet.TYPE_FORWARD_ONLY,ResultSet.CONCUR_UPDATABLE);
    pStmt.setString(1, fileDesign.getItem_code());
    rs = pStmt.executeQuery();
    if (rs.next()) {
      Blob blob = rs.getBlob("ITEM_IMAGE");
      blob.truncate(0);
      blob.setBytes(1, fileDesign.getFile()); //here getFile() returns byte[] and causes exception here
      rs.updateBlob("ITEM_IMAGE", blob);
      rs.updateRow();
    }
  }
  finally {
    if(rs != null) rs.close();
    if(pStmt != null) pStmt.close();
  }

上面的代码在我的本地系统中工作正常但在生产环境中产生以下异常：

已经坚持了几天： 这里可能出现什么问题？
