我用Digester组件从xml里读出数据，然后插入数据库,老是出问题，请高手指点！！！

1...............table_data.xml
<?xml version="1.0" encoding="gb2312"?>
<t_xml create_date="Sun Jun 18 23:40:30 CST 2006">
<record id="1">
<name>Zhang San</name>
<sex>male</sex>
<birthday>1982-10-21</birthday>
<lucknum>0.0</lucknum>
</record>
<record id="2">
<name>Li Si</name>
<sex>male</sex>
<birthday>1988-05-14</birthday>
<lucknum>0.0</lucknum>
</record>
</t_xml>
2.MySQL数据库的表t_xml为:
name varchar(50), sex varchar(10), birthday Date, lucknum double.

3...........和表t_xml对应的Bean是:
package cy;

import java.sql.Date;

public class TableData {
private String name;
private String sex;
private Date birthday;
private double lucknum;

public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public double getLucknum() {
return lucknum;
}
public void setLucknum(double lucknum) {
this.lucknum = lucknum;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}

4...........连接数据库用的类
package cy.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Common4DB {
private static Connection con = null;
public static Connection connDB(){
try{
Class.forName("com.mysql.jdbc.Driver");
} catch(ClassNotFoundException e) {
System.out.println("没有找到驱动");
}

String url = "jdbc:mysql://localhost/test";

try {
con = DriverManager.getConnection(url, "root", "1234");
return con;
} catch (SQLException e) {
e.printStackTrace();//这个地方的细节。
return null;
}
}
}

5...........我的导入程序如下:
package cy;

import java.io.File;
import java.io.IOException;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;

import org.apache.commons.digester.Digester;
import org.xml.sax.SAXException;

import cy.tablebean.TableData;
import cy.util.Common4DB;

public class InputData {

public void input2DB(TableData tableData) throws SQLException {
Connection conn = Common4DB.connDB();
String sql = "insert into t_xml values(?, ?, ?, ?)";
//String sql = "insert into t_xml(name, sex) values(?, ?)";
PreparedStatement ps = conn.prepareStatement(sql);

int i = 1;
ps.setString(i++, tableData.getName());
ps.setString(i++, tableData.getSex());
ps.setDate(i++, tableData.getBirthday());
ps.setDouble(i++, tableData.getLucknum());
ps.executeUpdate();
ps.close();
conn.close();
}

private void digestXML() throws IOException, SAXException {
Digester digester = new Digester();
digester.setValidating(false);

digester.addObjectCreate("t_xml", InputData.class);
digester.addObjectCreate("t_xml/record", TableData.class);

digester.addCallMethod("t_xml/record/name", "setName", 0);
digester.addCallMethod("t_xml/record/sex", "setSex", 0);
digester.addCallMethod("t_xml/record/birthday", "setBirthday", 0);
digester.addCallMethod("t_xml/record/lucknum", "setLucknum", 0);

digester.addSetNext("t_xml/record", "input2DB");

String fileName = "table_data.xml";
String fileNameFull = "xml/" + fileName;
InputData db = (InputData) digester.parse(new File(fileNameFull));
}

public static void main(String[] args) throws IOException, SAXException {
InputData inputData = new InputData();
inputData.digestXML();

}

public InputData(){}
}

报错信息如下:
org.apache.commons.digester.Digester endElement
严重: End event threw exception
java.lang.NoSuchMethodException: No such accessible method: setBirthday() on object: cy.tablebean.TableData

错误提示是说没有setBirthday()方法....

但是我在TableData这个类里，确实写了setBirthday()这个方法！！！！

现在又出现下面这个异常！畸形的url异常是什么意思？
java.net.MalformedURLException

问题解决了：
是我读取xml文件的路径设的不对！
