[求助]jsp+sql server2000中文乱码问题

　小弟最近换了2000数据库，连接一切正常，但是从jsp页面向数据库中插入中文出现了？？？的乱码，看了网上很多文章，解释的都不好，问题依旧没有解决，希望坛子里的高手不吝赐教，先附上全部源代码．我的系统：winXP(sp2)+tomcat5.028+sql server2000(sp4)+jdk1.4.2+jdbc for sql server2000.

程序源代码如下：DataBaseConnection.java

　package com.jspdev.util;
import java.sql.*;
public class DataBaseConnection
{
public static Connection getConnection()
{
Connection con=null;
String CLASSFORNAME="com.microsoft.jdbc.sqlserver.SQLServerDriver";
String SERVANDDB="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=jspdev";
String USER="kingwen";
String PWD="664711";
try
{

Class.forName(CLASSFORNAME);
con = DriverManager.getConnection(SERVANDDB,USER,PWD);
}
catch(Exception e)
{
e.printStackTrace();
}
return con;
}
}

MessageBean.java

package com.jspdev.ch9;
import com.microsoft.jdbc.sqlserver.SQLServerDriver;
import java.sql.*;
import java.util.*;

public class MessageBean
{
private Connection con;
MessageVO msg;

//获得数据库连接。
public MessageBean()
{
String CLASSFORNAME="com.microsoft.jdbc.sqlserver.SQLServerDriver";
String SERVANDDB="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=jspdev";
String USER="kingwen";
String PWD="664711";
try
{

Class.forName(CLASSFORNAME);
con = DriverManager.getConnection(SERVANDDB,USER,PWD);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void setMessage(MessageVO msg)
{
this.msg=msg;
}
public void addMessage()throws Exception
{
try
{
PreparedStatement stm=con.prepareStatement("insert into message values(?,?,?,?,?)");
stm.setString(1,msg.getTitle());
stm.setString(2,msg.getName());
stm.setDate(3,new java.sql.Date(new java.util.Date().getTime()));
if((msg.getEmail()).length()==0)
stm.setString(5,null);
else stm.setString(5,msg.getEmail());
stm.setString(4,msg.getContent());
try
{
stm.executeQuery();
}
catch(Exception e)
{
}

con.close();
}
catch(Exception e)
{
e.printStackTrace();
throw e;
}
}
public Collection getMessage()throws Exception
{
Collection ret=new ArrayList();
try
{
Statement stm=con.createStatement();
ResultSet result=stm.executeQuery("select count(*) from message");
int message_count=0;
if(result.next())
{
message_count=result.getInt(1);
result.close();
}
if(message_count>0)
{
result=stm.executeQuery("select * from message order by time desc");

while(result.next())
{
String title=result.getString("title");
String name=result.getString("name");
String mail=result.getString("mail");
String content=result.getString("content");
java.sql.Date date=result.getDate("time");
MessageVO message=new MessageVO();
message.setName(name);
message.setTitle(title);
message.setContent(content);
message.setDate(date);
message.setEmail(mail);
ret.add(message);
}
result.close();
stm.close();
}

con.close();

}
catch(Exception e)
{
e.printStackTrace();
throw e;
}
return ret;
}
}

MessageVO.java

package com.jspdev.ch9;
public class MessageVO implements java.io.Serializable
{
private String name,email,title,content;
private java.sql.Date date;
public void setName(String name)
{
this.name=name;
}
public void setEmail(String email)
{
this.email=email;
}
public void setTitle(String title)
{
this.title=title;
}
public void setContent(String content)
{
this.content=content;
}
public String getName()
{
return this.name;
}

public String getContent()
{
return this.content;
}
public String getTitle()
{
return this.title;
}
public String getEmail()
{
return this.email;
}
public java.sql.Date getDate()
{
return this.date;
}
public void setDate(java.sql.Date date)
{
this.date=date;
}
}

stm.setString(1,msg.getTitle());
在这里你可以先对msg.getTitle()的值进行编码(ISO-8859-1)
应该可以的.
