不要連密碼都忘掉了喔... @.@"

第二個作業

就是今天大家練習的東西
把Hello JSP Using Eclipse這個教學中的最後一個使用JSTL執行成功的JSP頁面
裡面輸入自己的名字，貼出來就可以了~

還有我已經幫大家改好標題了
以後交作業的標題後面就加上一個by 作者
Design Pattern的作業
如果是範例圖的話
要加上程式碼
記得程式碼要用<pre></pre>包起來才能固定格式喔~

Tontie For J2ME

不知道大家知道不知道Tontie 看名字可以有點陌生讓我們看一下底下這個link 知道了吧就是這個好玩的Game 好玩的是 Tontie有J2ME的版本耶!! 真是太Cool了

ScreenShot：

Cheat：

Press * Full health
Press # 1000 gold
Press Clear Go to the shop
Press Send Next level看起來是不相當好玩的樣子呢~~

而且他還是OpenSource的喔! 可以把原始碼拿來研究一下也可以自己寫個Tontie一類的應該滿cool的趕快來去網站看一下http://tunah.net/~tunah/tontie/

PO文範本

由於預設的自動換行格式會很奇怪地加上許多換行的<br />標籤
造成版面不好控制
所以之後大家就直接用標準的XHTML語法來po文章吧
最簡單的方式就是在每一行後面，加上換行的<br />標籤
我也幫大家準備了一個範本
大家po完文章記得把這些文字弄掉喔~ :)

<!-- 範本
段落：<p></p>
換行：<br />
固定格式：<pre></pre>
超連結：<a href=""></a>
加強：<em></em>
