[求助]会写网页源代码的进~~【未解决】

我用eclipse写的
要导入包<%@taglib prefix="movie" uri="/WEB-INF/movie.tld"%>
而在包里创建的代码是package com.tman.forum.tag;

import

import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.tagext.SimpleTagSupport;

public class SelectTag extends SimpleTagSupport {
    private String name;
    private int begin;
    private int end;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getBegin() {
        return begin;
    }

    public void setBegin(int begin) {
        this.begin = begin;
    }

    public int getEnd() {
        return end;
    }

    public void setEnd(int end) {
        this.end = end;
    }

    public void doTag() {
        JspWriter out = this.getJspContext().getOut();
        StringBuffer sb = new StringBuffer();
        try {
            sb.append("<select name="+name+">");
            for (int i = begin; i < end; i++) {
                sb.append("<option value=");
                sb.append(i);
                sb.append(">");
                sb.append(i);
                sb.append("</option>");
            }
            sb.append("</select>");
            out.write(sb.toString());
        } catch (IOException e) {

        }
    }

}
界面：
<tr>
                    <td>
                        出生年月;
                    </td>
                    <td>
                        <movie:select name="year" begin="1960" end="2007" />
                        年
                        <movie:select name="month" begin="1" end="12" />
                        月
                        <movie:select name="day" begin="1" end="31" />
                        日
                    </td>
                </tr>
