这是一个小型的白板程序，我把所有的文件都copy过来，大家帮忙分析一下究竟是哪里的问题，谢谢了：
共6个文件：两个javabean（ JBoardBean.java，LogDataBean.java)，一个MakeSuggestion.html，一个JBoard.jsp，一个Uh-oh.jsp，一个SuggestionLog.jsp：
JBoardBean.java：
package hh;
import java.text.DateFormat;
import java.util.Date;
public class JBoardBean
{
private String name,login,date,domain,suggestion,PATH;
public void setName(String name)
{
this.name=name;
}
public void setLogin(String login)
{
this.login=login;
}
public void setDomain(String domain)
{
this.domain=domain;
}
public void setSuggestion(String suggestion)
{
this.suggestion=suggestion;
}
public void setPATH(String PATH)
{
this.PATH=PATH;
}
public String getDate()
{
return date;
}
public String getName()
{
return name;
}
public String getLogin()
{
return login;
}
public String getDomain()
{
return domain;
}
public String getSuggestion()
{
return suggestion;
}
public String getPATH()
{
return PATH;
}
public JBoardBean()
{
date=DateFormat.getInstance().format(new Date());
}
}
LogDataBean.java：
package hh;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
public class LogDataBean
{
private BufferedWriter bw;
private String date,domain,login,logPath,name,suggestion;
private String fileName="/data/SuggestionLog.inc";
private StringBuffer sb1=new StringBuffer();
private StringBuffer sb2=new StringBuffer();
private StringBuffer emailUrl;
private String TRuser="<tr><td id=\"user\">";
private String TRdata="<tr><td id=\"data\">";
private String TRclose="</td></tr>";
public synchronized void setSuggestion(String suggestion)
{
this.suggestion=suggestion;
try
{
bw=new BufferedWriter(new FileWriter(logPath+fileName,true));
emailUrl=new StringBuffer("<a href=\"mailto:").append(login).append("@").append("\">").append(name).append("</a>");
bw.write(sb1.append(TRuser).append(date).append(" ").append(emailUrl).append("wrote:").append(TRclose).toString());
bw.newLine();
bw.write(sb2.append(TRdata).append(suggestion).append(TRclose).toString());
bw.newLine();
bw.close();
sb1.setLength(0);
sb2.setLength(0);
}
catch(IOException e)
{
System.err.println(e);
e.printStackTrace();
}
}
public synchronized void setLogPath(String logPath)
{
this.logPath=logPath;
}
public synchronized void setName(String name)
{
this.name=name;
}
public synchronized void setLogin(String login)
{
this.login=login;
}
public synchronized void setDate(String date)
{
this.date=date;
}
public synchronized void setDomain(String domain)
{
this.domain=domain;
}
public LogDataBean()
{
}
}

<p><a href="<%=request.getContextPath()%>">back to main JBoard page</a>

从JBoard.jsp到SuggestionLog.jsp后，应该把SuggestionLog.inc的内容显示出来，但是，到了SuggestionLog.jsp页面后，只显示了：
JBoard:Suggestion Log
back to main JBoard page
我不知道究竟是哪里的问题，困扰好几天了，实在是没辙了，望各位大侠帮忙分析一下，先谢啦！
