= 一. 下載資源 =
== 1.A 用 virtualbox 虛擬機器 ==
* [http://secuse.nchc.org.tw/jspservlet/u1004.vdi 下載 virtualbox 的硬碟檔]
* 此硬碟檔為ubuntu 10.04 版本，已經調整好教材，請用virtualbox 3.2.2 以上版本掛載
== 1.B 自行下載資源 ==
1. [http://secuse.nchc.org.tw/jspservlet/jspservlet%e5%88%9d%e9%9a%8e.pdf 下載 pdf 手冊][[BR]]
2. [http://secuse.nchc.org.tw/jspservlet/tomcat-6.0.26.tar.gz 下載tomcat 6.5]
3. [http://secuse.nchc.org.tw/jspservlet/eclipse-SDK-3.5.2-linux-gtk.tar.gz 下載 eclipse 3.5 linux版]
= 二. 實做簡單的 servlet 範例 =
已將tomcat 安裝於 /opt/tomcat/ 目錄下
== 2.1 建立目錄 ==
{{{
cd /opt/tomcat/webapps/
mkdir -p /opt/tomcat/webapps/FirstServlet/WEB-INF/classes
mkdir /opt/tomcat/webapps/FirstServlet/WEB-INF/lib
}}}
== 2.2 第一個程式:HelloServlet.java ==
{{{
cd /opt/tomcat/webapps/FirstServlet/WEB-INF/classes
gedit HelloServlet.java
}}}
{{{
#!java
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloServlet extends HttpServlet {
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String name = request.getParameter("name");
out.println("");
out.println("");
out.println("Hello Servlet");
out.println("");
out.println("");
out.println(" Hello! " + name + " !
");
out.println("");
out.println("");
out.close();
}
}
}}}
== 2.2 編譯:HelloServlet.java檔 ==
{{{
cd /opt/tomcat/webapps/FirstServlet/WEB-INF/classes
javac -classpath /opt/tomcat/lib/servlet-api.jar ./HelloServlet.java
}}}
== 2.3 製作佈署描述檔:web.xml ==
{{{
cd /opt/tomcat/webapps/FirstServlet/WEB-INF/
gedit web.xml
}}}
{{{
#!xml
HelloServlet
HelloServlet
HelloServlet
/hello.do
}}}
== 2.4 啟動web容器:tomcat ==
{{{
cd /opt/tomcat
bin/startup.sh
}}}
== 2.5 用瀏覽器測試 ==
[http://localhost:8080/FirstServlet/hello.do?name=caterpillar]
ps: '''?name=caterpillar''' 可以改成你的名子來測試是否成功
