推荐apache的common-upload，上传数据库和放到制定文件任选，而且都有简单样例代码。
至于分页，给你一个简单的分页代码吧(效能不高，需要优化):
具体分页类：

Java code

import java.util.*;public class Pager {        private String PageUrl;    private boolean hasNext;    private boolean hasPrevious;    private String previousPage;    private String nextPage;    private int offset;    private int size;    private int length;    private int pagenumber;        public Pager(int offset,int length, int size, String url){        this.offset=offset;        this.length=length;        this.size=size;        int index=url.indexOf("&pager.offset");        if (index>-1){            this.PageUrl=url.substring(0,index);        }else{            this.PageUrl=url;        }    }    public void setoffset(int offset){        this.offset=offset;    }    public void setPagerUrl(String PagerUrl){        this.PageUrl=PagerUrl;    }    public void setsize(int size){        this.size=size;    }    public void setlength(int length){        this.length=length;    }    public int getoffset(){        return this.offset;    }    public String getPageUrl(){        return this.PageUrl;    }    public boolean gethasNext(){        if((offset+1)*length>=size){            hasNext=false;        }else{            hasNext=true;        }        return hasNext;    }    public boolean gethasPrevious(){        if(offset>=1){            this.hasPrevious=true;        }else{            this.hasPrevious=false;        }        return hasPrevious;    }    public String getpreviousPage(){        this.previousPage="";        if (this.gethasPrevious()){            this.previousPage=this.PageUrl+"&pager.offset="+(offset-1);        }        return previousPage;    }    public String getnextPage(){        this.nextPage="";        if(this.gethasNext()){            this.nextPage=this.PageUrl+"&pager.offset="+(offset+1);        }        return this.nextPage;    }    public int getpagenumber(){        float temppn=(float)size/(float)length;        pagenumber=new Float(temppn).intValue();        if (temppn>pagenumber){            this.pagenumber++;        }        return this.pagenumber;    }    public static ArrayList FindPageList(int offset,int length,List list){        ArrayList alist=new ArrayList();        for(int i=offset*length; i<(offset*length+length)&&i<list.size();i++){            alist.add(list.get(i));        }        return alist;    }    }
