一个TagSupport的问题！找一半天了都没找出问题来！请大家帮我看一下！

Question

这是我的代码:PaginationTag.java
package com.xncf.taglib;
import java.util.List;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.TagSupport;import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.xncf.dao.ArchiveDao;
import com.xncf.model.Archive;
public class PaginationTag extends TagSupport {
private int categoryId;
private int pages;
private static Log log = LogFactory.getLog(ArchiveDao.class);
private ArchiveDao archiveDao;
private static final long serialVersionUID = 1L;
public int doStartTag()throws JspException{
return EVAL_BODY_INCLUDE;
}

public int doEndTag()throws JspException{
BeanFactory factory=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
ArchiveDao archiveDao =(ArchiveDao)factory.getBean("archiveDao");
List<Archive> archives=(List<Archive>) archiveDao.show(categoryId);
pageContext.setAttribute("archives", archives);
return EVAL_PAGE;
}
public ArchiveDao getArchiveDao() {
return archiveDao;
}
public void setArchiveDao(ArchiveDao archiveDao) {
this.archiveDao = archiveDao;
}
public int getCategoryId() {
return categoryId;
}
public void setCategoryId(int categoryId) {
this.categoryId = categoryId;
} public int getPage() {
return pages;
} public void setPage(int pages) {
this.pages = pages;
}
}
这是dao文件名为:ArchiveDao.java
package com.xncf.dao;import java.io.IOException;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import java.util.List;
import java.util.Properties;import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.jdbc.core.JdbcTemplate;import com.xncf.model.Archive;
import com.xncf.model.Category;
import com.xncf.utils.MyUtils;
import com.xncf.utils.Sys;
public class ArchiveDao implements DAO {
private static Log log = LogFactory.getLog(ArchiveDao.class);
Properties properties = null;
private JdbcTemplate jdbcTemplate;
public List<?> pagination(int categoryId,long totals) {
try{
properties=Sys.loadPropertiesResource(PROPERTIES_RESOURCE);
}catch(IOException ioe){
log.error(ioe.toString());
}
String sql="SELECT * FROM ( SELECT TOP 25 * FROM (SELECT TOP " +totals+
" * FROM Archive where category_Id="+categoryId+" order by Release_Date desc) t1) t2 Order by Archive_Id DESC";;
List<Archive> list=null;
if(categoryId==0){//如果值为0则显示全部数据
sql="select * from Archive inner join Category on Archive.Category_Id=Category.Category_Id order by Release_Date DESC";
list=jdbcTemplate.query(sql,new ArchiveMapper());
}else{
list=jdbcTemplate.query(sql,new ArchiveMapper());
}
System.out.println(sql+"分页时的SQL");
return list;
}
}application.xml的配置
  <bean id="paginationTag" class="com.xncf.taglib.PaginationTag">
      <property name="archiveDao"> <ref local="archiveDao"/> </property>
  </bean>archive.tld
<?xml version="1.0" encoding="utf-8"?>
<taglib>
  <tlib-version>1.2</tlib-version>
  <jsp-version>1.2</jsp-version>
  <short-name>Show</short-name>
  <description>
     showArchive
  </description>
  <tag>
  <name>showArchive</name>
  <tag-class>com.xncf.taglib.PaginationTag</tag-class>
  <body-content>empty</body-content>
      <attribute>
        <name>categoryId</name>
        <required>true</required>
        <rtexprvalue>true</rtexprvalue>
      </attribute>
      <attribute>
        <name>page</name>
        <required>true</required>
        <rtexprvalue>true</rtexprvalue>
      </attribute>
  </tag>
</taglib>
以下是提示的错误：

Answer 1

org.apache.jasper.JasperException: /pagination.jsp(29,4) Unable to load tag handler class "com.xncf.taglib.PaginationTage" for tag "pagination:archive" 异常：org.apache.jasper.JasperException 
发生位置：/pagination.jsp 29行. 
原因：不能加载标签“pagination：archive”的处理类“com.xncf.taglib.PaginationTage” 具体没看出来...没有你这么用过...可以说详细点吗？
混个眼熟.
