帮帮忙 实现struts上传
原来的代码如下：
AActionForm.java
package com.sql.struts;
import org.apache.struts.action.ActionForm;
public class AActionForm extends ActionForm{
String id=null;
String name=null;
String password=null;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
DBConn.java
package com.sql.struts;
import java.sql.*;
public class DBConn{

Connection conn=null;
ResultSet rs=null;
public DBConn(){
try{
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e){
System.out.println( "Jdbc_conn(): "+e.getMessage());
}
}
public void executeUpdate(String sql)throws Exception{
//sql=new String(sql.getBytes( "GBK "), "ISO8859_1 ");
try{
conn=DriverManager.getConnection(sConnStr);
Statement stmt=conn.createStatement();
stmt.executeUpdate(sql);
conn.close();
stmt.close();
}
catch(SQLException ex){
System.out.println( "sql.executeUpdate: "+ex.getMessage());
}
}
public ResultSet executeQuery(String sql)throws Exception{
rs=null;
try{
sql=new String(sql.getBytes( "ISO-8859-1 "));
conn=DriverManager.getConnection(sConnStr);
Statement stmt=conn.createStatement();
rs=stmt.executeQuery(sql);
}
catch(SQLException ex){
System.out.println( "sql.executeQuery: "+ex.getMessage());
}
return rs;
}
public void CloseConn()
throws Exception {
try
{
if (rs!=null)
rs.close();
if (conn!=null)
conn.close();
}
catch(SQLException ex)
{
System.out.println ( "closeConn: " + ex);
}
}
}

剛學這個的時候仿照孫為琴的書寫的上傳代碼，裏面還有一些其它數據，不需要看，編碼問題業已解決. 孫為琴的書裏（精通struts...那本）的例子也得就很好，感謝孫姐，呵呵。 學struts應該有一本她的書
[解决办法]
不是阿
<html:file property= "file "/> 是上傳文件的控件
[解决办法]
form里要建一个struts file的set\get然后再建一个vo其中那一个bety[]的set/get，最后通过sql把VO对向传入数据库
[解决办法]
其实可以看一下struts html.tga的示例就明白了
