HTML里的valign、align
使用 VAlign 属性指定由 HtmlTableCell 类的实例所表示的单元格内容的垂直对齐方式。align是左右对齐方式。
“VALIGN"意思 -- vertical alignment 垂向对齐方法
其值可以是top -- 顶部；或middle -- 中部；或bottom-- 底部；或baseline -- 基线。默认中部--middle。
align是左右对齐方式。
其值：align="middle"内容居中、 align="left" 内容居左、 align="rigth" 内容居右。

遭遇ORA-01461
oracle 版本:9.2i
驱动版本:classes12.jar for 10.2.0.3.0
数据类型:clob
当插入中文数据在2000字符左右时就会抛出这个错误
--- The error occurred in cn/gov/gzjs/conf/article.xml.
--- The error occurred while applying a parameter map.
--- Check the insertArticle-InlineParameterMap.
--- Check the statement (update failed).
--- Cause: java.sql.SQLException: ORA-01461: 仅可以为插入 LONG 列的 LONG 值赋值
超过 或 少于 都没有问题
郁闷啊

用Diff和Patch工具维护源码
在Unix系统下，维护源码版本可以使用很多方法，其中最常用的当然是大名鼎鼎的CVS，但实际上，简单的版本维护工作并没有必要使用复杂的CVS等专门的版本维护工具，Unix标配中的diff和patch工具就完全可以完成代码的简单备份和升级工作。
