# JSP/Servlet learn 30 Day

___
### Day 1
___
1. Install Tomcat
2. Install Eclipse IDE
3. Create Servlet.java
**(編輯 java package 跟 Class name 按到下一步要把自動產生 web.xml檔打勾**
** @WebServlet("/LoginServlet") 是對應的URL**

4.新增 Server Runtime

**project左鍵-> Bulid Path-> Configure Bulid Path-> 選Libraries-> Classpath 欄按 Add Library->Server Runtime-> 選剛下載的Tomcat-> Finish**

5. 設定web.xml(在WEB-INF 把web.xml設定方式加進來,調整成只要url有/,後面不管接什麼就直接呼叫Servlet)

<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>com.servlet.LoginServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

6. 新增 login.jsp and index2.jsp(index2是因為預設是index會直接讀取到所以改名子）

<form action="LoginServlet" method="post">
<div >
<table>
<tr>
<td>
<h1>User Name:</h1><input type="text" name="name" />
</td>
</tr>
<tr>
<td>
<h2>Password:</h2><input type="password" name="mypassword" >
<input type="submit" value="submit">
</td>
</tr>
</table>
</div>
</form>
