本文转自�Q?a >http://www.b9527.net/?q=node/1124

原文如下�Q?/div>

1. 写入文�g的格�?

写入 Xml 文�g的时候默认是全部内容写�ؓ一行，�q�个可以通过加入 Format 来解冻I��

OutputFormat format = OutputFormat.createPrettyPrint();

2. Xml 中文问题

2.1 Xml 最好设�?UTF-8 格式�Q?/p>

format.setEncoding("utf-8");

2.2 不要�?FileWriter 输出双字节，改�ؓ FileOutputStream 输出单字节：

XMLWriter output = new XMLWriter(new FileOutputStream(configFile), format);

3. CDATA�c�d��文本输入

Element conTblOpr = rowElement.addElement(XmlDBConstants.CON_TBL_OPR);// 加入节点

DefaultCDATA conTblOprCdata = new DefaultCDATA(conTblOprField);// CDATA格式�?/p>

conTblOpr.add(conTblOprCdata );// 加入CDATA文本

Dom4j 里面已经内置了对 CDATA �c�d��文本的支持，不要��编码去在文本两边加�?/p>

实施WebService Security[WS-Security1.0]的Encrypt和Sign模式(XFire+WSS4J)

thanks for springside

鉴于很多�pȝ��需要实施WS-Security的标准，我们在SpringSide中提供了XFire+WSS4J的Demo�Q�本文介�l�SpringSide中Spring+XFire+WSS4J的基本配�|?br />
[WebService Server端配�|�]
�W�一�Q�创��Z��个基本的BookService

public interface BookService {
    /** *//**
     * 按书名模�p�查询图�?br />      */
    List findBooksByName(String name);

    /** *//**
     * 查找目录下的所有图�?br />      *
     * @param categoryId 如果category为null�?#8220;all”�Q?nbsp;列出所有图书�?br />      */
    List findBooksByCategory(String categoryId);

    /** *//**
     * 列出所有分�c?
     *
     * @return List�Q�或是null�?br />      */
    List getAllCategorys();
}

�W�二�Q�接口扩展，即Extend基本的BookService�Q�在XFire中，不同的WSS4J�{�略需要针对不同的ServiceClass�Q�否�?lt;inHandlers>里面的定义会Overlap�?

�q�样的话baseTxProxy也可能被实例化。是不是加上abstract�Q?true"属性，把baseTxProxy只是当作一个模板比较好�Q�因为只需要itemservice�q�个bean�?

IE6�?SELECT 标记忽略 Z-index BUG

Bug描述�Q?SELECT elements ignore Z-index ("windowed element" problem)
�q�接�Q�http://www.throbs.net/web/articles/IE-SELECT-bugs/#ieZIndex

问题原因�Q?br /> 1. select html标记在IE6下的解析不管Z-index
2. div 不能遮盖select,

解决思�\:
1. 在select上用iframe遮盖
2. 在iframe上用div遮盖
3. iframe的width,height,top,left与div一样大.

�C�Z��代码
#zindexDiv{
position:absolute;
z-index:50;
width:expression(this.nextSibling.offsetWidth);
height:expression(this.nextSibling.offsetHeight);
top:expression(this.nextSibling.offsetTop);
left:expression(this.nextSibling.offsetLeft);
/*background-color:green;?ff????????,????????????????*/
