我这里有两个JAVABEAN的程序但无法编译请高人帮助

[koseureka]

一:PageBean.java
package com.webshop.page;
import java.util.Vector;
public class PageBean
{
public int curPage;
public int maxPage;
public int maxRowCount;
public int rowsPerPage=5;
public java.util.Vector data;
public PageBean()
{
}
public void countMaxPage(){
if(this.maxRowCount % this.rowsPerPage==0){
this.maxPage=this.maxRowCount/this.rowsPerPage;
}else{
this.maxPage=this.maxRowCount/this.rowsPerPage+1;
}
}
public Vector getResult()
{
return this.data;
}
public PageBean(PageBusiness pageBusiness,String con)throws Exception
{
this.maxRowCount=pageBusiness.getAvailableCount(con);
this.data =pageBusiness.getResult();
this.countMaxPage();
}
}
二:PageBusiness.java
package com.webshop.page;
import java.sql.*;
import java.util.*;
public abstract class PageBusiness
{
public java.util.Vector v;
public abstract int getAvailableCount(String conditions)throws Exception;
public java.util.Vector getResult()throws Exception
{
return v;
}
protected final int getAvailableCountHelper(Connection conn,String tableName,String conditions)throws Exception
{
int ret=0;
Statement stmt=conn.createStatement();
String strSql="select count(*)as counters from"+tableName+"where"+conditions;
ResultSet rset=stmt.executeQuery(strSql);
while(rset.next())
{
ret=rset.getInt(1);
}
return ret;
}
public abstract PageBean listData(String page,String conditions)throws Exception;
}

怎么也没办法纺译...那位达人救救我~~
