㈣ 關於一些JSP程序設計的問答題，我不懂。幫幫忙。
1:servlet
2:在JSP的3種指令中，用來定義與頁面相關屬性的指令是（page ），回用於在JSP頁面中包括另一個文件的答指令是（ include ），3: <jsp:include>
4: GB2312
5:<%-- 這是注釋的內容 --%>
6 A 指令元素是:<%@ %>
7 A 當成字元串來輸出
8 B D都對 A是因為Int 的i應該小寫 <%=%>這是表達式的寫法,後不用加冒號
9:D
10:B import用來導入包和類的
11：D <%@ include file="relativeURL"%>這是jsp的指令元素
㈤ jsp編程題
就好了,完整代碼如下，記得jar驅動放好,如果輸出的是內存地址的話就證明配置沒問題，不然就是你的操作或者配置問題了：
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class BaseDao {
private static final String DRIVER_CLASS="com.microsoft.sqlserver.jdbc.SQLServerDriver";
private static final String URL="jdbc:sqlserver://localhost:1433;DATABASENAME=managerNews";
private static final String UNAME="sa";
private static final String UPASSWORD="sa";
/*
* 連接資料庫
*/
public Connection getConnection(){
Connection conn=null;
try {
Class.forName(DRIVER_CLASS);
conn=DriverManager.getConnection(URL,UNAME,UPASSWORD);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return conn;
}
/*
* 關閉conn，ps，rs，釋放資源
*/
public void closeAll( Connection conn, PreparedStatement ps, ResultSet rs ) {
/* 如果rs不空，關閉rs */
if(rs != null){
try catch (SQLException e)
}
/* 如果pstmt不空，關閉pstmt */
if(ps!= null){
try catch (SQLException e)
}
/* 如果conn不空，關閉conn */
if(conn != null){
try catch (SQLException e)
}
}
// public static void main (String[] args){
//
// BaseDao bo= new BaseDao();
// Connection conn=null;
// conn=bo.getConnection();
// System.out.print(conn);
//
// }
}
