忙里偷闲
研究了一下webservice，做了个hello world
一点理解，xfire能把一个普通java类映射成web服务
首先要建立一个供外部调用的接口interface
然后建立一个类实现这个接口
再然后在service.xml中配置web服务的名字，名称空间，接口类名，实现接口的类名，这个service.xml文件要放在src/META-INF/xfire/services.xml
最后在web.xml中配置xfire 的servlet
OK了
===============接口HelloWorldService 类==================

    public String sayHello();

}
==============接口实现类HelloWorldServiceImpl =====================

Struts 禁用的错误

遇到这样一个问题
页面中有几个数据项用struts的<html:select>标签展示，今天提出新的需求，要不允许修改这几个<html:select>，那就禁用咯，这样问题发现了，这个页面是来自action，给<html:select>对应actionForm中的属性付了值，页面显示<html:select>自然就选中被赋值的选项，但是提交表单的时候，数据保存的确总是<html:select>列表中的第一个值，如果去掉禁用，就正常了。晕。
试着在onload中用js禁用也不行
在网上搜到一个这样的写法，实现readonly了<select onbeforeactivate="return false" onfocus="this.blur()" onmouseover="this.setCapture()" onmouseout="this.releaseCapture()">

<option>1</option>
</select>
不过要用到<html:select>中要把onbeforeactivate="return false" 去掉，<html:select>不认识这个属性，不过效果还是实现了。

相当相当隐蔽的错误 org.hibernate.hql.ast.QuerySyntaxException: unexpected token

今天周末，被头儿过来改bug
其中一个在hql查询的时候报org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ApplyInfo near line 1, column 23这样的错误，貌似看起来hibernate不认识ApplyInfo这个映射持久类，但是这个类非常确定的是已经映射了，而且在别处用的非常正常。郁闷，找啊找
在网上找org.hibernate.hql.ast.QuerySyntaxException: unexpected token的错误有
1、持久类写错了，要不就是写成了数据库表名
2、hibernate3.0不支持select中嵌套查询，据说from中也不行，只支持where中嵌套查询，好像3.1支持了select中嵌套
3、sql语句中字段是用了保留关键字

然后就是我发现的这个隐蔽错误了
发现的from后的空格是一个全角的空格，半角空格，全角　空格。距离比一样啊，原来就看出from后面的空格大了，还以为是两个空格呢。

隐蔽，太隐蔽了。

给页面加一层半透明div，禁用页面所有功能

系统中有个功能用户点击一个按钮要调用webservice，可能会等待较长时间，如果用户不耐烦，再点按钮或点击别的功能就乱套了
想到屏蔽页面所有功能，思路是用户点击按钮，调用一个javascript方法，显示预先在页面中定义好的隐藏div，返回结果后再隐藏div，允许用户继续操作。

==========================================================

<html>
<head>
    <title>半透明div</title>

   <style>
