开发环境配置：Eclipse3.0.2, Hibernate2.0, MYSQL数据库。

              打开MYSQL Command Line Client(MYSQL 服务器的客户端交互程序），

              输入ROOT用户登录密码。即你在安装MYSQL服务器时，为ROOT用户设置

              的密码。显示登录成功。创建数据库，此处命名为：learndiary. 输入

              use learndiary，起用此数据库; 注意以分号结尾。创建表：temp.

              表中包括的字段为：

              id bigint, name char(15), value char(30), description text.

              将hibernate.jar, hibernate-tools.jar包考贝到你所要测试的项目的lib

              目录下。如果你想为你的测试程序加入日志追踪，将common-logging.jar

              也考入lib目录下。

lay and lie

lay-laid-laid-laying

lie-lay-lain-lying

I always lay the book on the table.(action)

The book is lying on the table.(status)

Daughter is growing

1.She can count number from 1 to 10,if she is happy then.But,the status isn't stable;

2.She can resite ancient poems,such as <<静夜思>>，＜＜鹅＞＞，＜＜锄禾＞＞，etc...,although the pronounciation isn't accurate.This is her mother's result:);

3.She can disguise crying if she isn't happy for something,not the real crying:)

4.Her health status is better and better than before.

application is first

I have found maybe we should reslove some application problems of this website at first.e.g.,improve the priority of this kind of issues.

This need exchanging information with other members.

give the freedom to user,form group spontaneously

1.with the XML technique,the articles of a user can be process freely;

2.a user can build a group with several goals spontaneously,like QQ group;

3.before a user creating a goal really,a searching process should be taken for avoiding some duplicate goal;

4.Maybe,if a user build a group,a approving process should be taken for avoiding some duplicate or improper group to be found.

a difficut:struts module

For my viewpoint,struts module should be a useful technique.It offer a framework to resolve a important aspect of OOP.

So,I think we can import this technique in our future Learndiary Version for extension goal.And,I have tried to use this in fileSharing trial system(there are problem in this using for my inapprehension on this technique.)

But,from some resource of learning it,I found there are many restricts on this-all of a module:include action,jsp,messageresource,datasource...,are added the module prefix automatically!e.g.,a path of jsp is:/WEB-INF/amodule/test.jsp,it will be /amodule/WEB-INF/amodule/test.jsp.And,the action is so too.

I feel the struts module is a bit complex.

introduce a eclipe plugin "Hibernate Synchronizer"

A small plugin,easy to understand and easy to use.I haven't contact Hibernate before and feel hibernate is very difficult to use,but,with the help of this plugin,I spent half a day to finish a Hibernate based demo.

But,I am doubtful,a tool so easy to use,the code created by it if is good or not?
