webservice--解析xml

客戶端請求的xml格式:

<?xml version="1.0" encoding="utf-8" ?>
<selectPage>
<start></start>
<end></end>
</selectPage>

服務器響應的xml格式:

<?xml version="1.0" encoding="utf-8" ?>
　　<selectPage>
　　　　<accountName></accountName>
</selectPage>

實體：

package com.zpark.yyl.entity;

import java.io.Serializable;

public class Account implements Serializable {
    private Integer accountNo;
    private String accountName;
    private String password;
    private Integer balance;
    //private java.util.Date openDate;
    
    public Integer getAccountNo() {
        return accountNo;
    }
    public void setAccountNo(Integer accountNo) {
        this.accountNo = accountNo;
    }
    public String getAccountName() {
        return accountName;
    }
    public void setAccountName(String accountName) {
        this.accountName = accountName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Integer getBalance() {
        return balance;
    }
    public void setBalance(Integer balance) {
        this.balance = balance;
    }
    
    public Account(Integer accountNo, String accountName, String password,
            Integer balance) {
        super();
        this.accountNo = accountNo;
        this.accountName = accountName;
        this.password = password;
