1 創建test1 Dynamic Web Project站點
2 創建Servlet 設置java package(com.servlet)和class name(MyServlet)。
設置：
選擇Add Library 
選擇tomcat
3 在WebContent/WEB-INF 下面創建web.xml文件。
Web.xml文件內容如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="
xmlns:xsi="
xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee <servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>com.servlet.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/MyServlet</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>MyServlet</welcome-file>
</welcome-file-list>
</web-app>
4 編寫MyServlet.java代碼
import java.io.PrintWriter;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.setContentType("text/html");
response.setCharacterEncoding("GBK");
PrintWriter out=response.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>servlet sample</TITLE></HEAD>");
out.println("<BODY>");
out.println("servlet 實例 ");
out.println(this.getClass());
out.println("</BODY>");
out.println("</HTML>");
out.flush();
out.close();
}
5 WebContent下面創建index.jsp
Body里面增加代碼<jsp:forward page="MyServlet"></jsp:forward>
6 運行結果如下：
servlet 實例 class com.servlet.MyServlet
備注：
MyServlet.java代碼修改
response.setContentType("text/html");
response.setCharacterEncoding("GBK");
PrintWriter out = response.getWriter();
out.print("<p>上下文路徑：" + request.getServletPath() + "</p>");
out.print("<p>HTTP請求類型：" + request.getMethod() + "</p>");
out.print("<p>請求參數：" + request.getQueryString() + "</p>");
out.print("<p>請求URI：" + request.getRequestURI() + "</p>");
out.print("<p>請求URL：" + request.getRequestURL().toString() + "</p>");
out.print("<p>請求Servlet路徑：" + request.getServletPath() + "</p>");
out.flush();
out.close();
運行結果：
上下文路徑：/MyServlet
HTTP請求類型：GET
請求參數：null
請求URI：/test1/MyServlet
請求URL：http://localhost:8080/test1/MyServlet
請求Servlet路徑：/MyServlet
注意：Web Deployment Assembly增加Add，對mysql.jar的引用
