用JSP编写通用信息发布程序

信息发布界面

提供发布信息的交互界面，调用 recordMessage.jsp程序。

sayMessage.jsp

 1<html> <head> <title> 信息发布</title>
 2<meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
 3<link href="css_01.css" rel="stylesheet"/>
 4<meta content="MSHTML 5.00.3103.1000" name="GENERATOR"/> </head>
 5<body>   
 6&lt;％ @ page contentType=“ text/html; charset=GB2312”％ &gt;

 8&lt;％ @ page language=“ java” import=“ java .sql .＊”％ &gt;

10<jsp: class="ymbean.opDb" id="rencommend" scope="page" usebean=""></jsp:>
11<form action="recordmessage.jsp" method="post" name="sign">
12<input name="dtkey" type="hidden" value="ta_routes"/>
13<table bgcolor="#d5e8fd" border="0" cellspacing="1" width="97%">
14<tbody>
15<tr> <td height="185" nowrap="" width="45%">
16<div align="left">
17<table bgcolor="#d5e8fd" border="0" cellspacing="1" width="100%">
18<tbody>
19<tr> <td nowrap="" width="100%">线路名称：

21</td>
22</tr>
23<tr><td nowrap="" width="100%">显示序号：   
24<input maxlength="3" name="routeno" size="36"/>
25</td></tr>
26<tr>
27<td width="100%">游览内容。文字超一行时 ,请您敲 Enter键换行</td>
28</tr>
29<tr><td height="162" width="100%">
30<textarea cols="55" name="c04" rows="9">   
31</textarea>
32</td>
33</tr></tbody></table></div></td></tr>
34<tr><td align="middle" colspan="2" nowrap="">
35<input name="cmdcommit" type="submit" value="提交"/>
36</td></tr></tbody></table>
37</form>
38<div></div></body></html>

连接数据库

通过调用 Java Bean连接 Oracle数据库。

opDb.java

package ymbean; // java包

import java.sql.＊ ;

public class opDb {

public opDb() { }

public ResultSet executeQuery(String sql)

{

ResultSet rs = null;

Statement lstmt = null;

try { lstmt = connectdb();

rs = lstmt.executeQuery(sql);

System.out.println(“ executeQuery:”＋ sql);

} catch(SQLException ex) { return(null)； }

return rs;

}

public String executeUpdate(String sql)

{

ResultSet rs = null;

Statement lstmt = null;

try {

lstmt = connectdb();

lstmt.executeUpdate(sql);

System.out.println(“ executeUpdate:”＋ sql);

lstmt.executeUpdate(“ commit” );

}catch(SQLException ex) {}

return(“ executeUpdate ok” );

}

//连接数据库

public Statement connectdb()

{ Statement lstmt=null;

Connection conn=null;

final String connect_string=“ jdbc:oracle:thin:scott/[email protected]:1521:test” ;

final String driver_string=“ oracle.jdbc.driver.

OracleDriver” ;

Connection lconn;

try { Class.forName(driverstr);

lconn=DriverManager.getConnection(connectstr);

lstmt=lconn.createStatement();

} catch (Exception e) { return(null);}

return lstmt;

}

}//end opDb.java
