从上班开始没多久�Q�就开始用Evernote�Q�是portable 2.2版本�?br />好记性不如烂�W�头。真的是做到了随手记�Q�尤其是搜烦功能��单易用，用来挖很久以前记下的tips�Q�界面也很简�z�，明了、够用�?br />备䆾也方便，反正换了�?sh��)脑�Q�文件夹直接拯��Q�数据没丢�?br />

虽然手头的v2.2完全满��我随手记一记的需求，但是�Q�本着与时��p��和稍微保证一下数据的安全性，我还是下了个最�q�的v4.x的版本，�l�果发现�q�是要从v3开始才能导入v2的数据。嗯�Q�看来是落后太久了�?br />有一点夸奖一下：免费账户的每月上传容量是有限的，但是对于我这�U�文本笔讎ͼ�够传3w条的�?br />

setQueryTimeout(int) is not yet implemented

春节�q�后�q�几天干的活儿就没一件痛痛快快的�Q?br />�W�一天是发现�~�译环境有异动，我以为是代码有问题，折腾�?天多。。�?br />�W�二天是自己机器上的IE8抽疯弄得我以为是build有问题。。�?br />�W�三天从TimesTen转到Psql的各�U�毛病。。�?br />
好吧。言归正传：
1�Q�找一个跟表无关的通用的单�U�的select语句作�ؓ��试语句不容易啊�Q?br />Dual是Oracle自带的表�Q�其他DBS木有的。。不用Dual的话Oracle又不认�?br />
2�Q�Cause: org.postgresql.util.PSQLException: Method org.postgresql.jdbc2.Jdbc2PreparedStatement.setQueryTimeout(int) is not yet implemented.
�q�个错误�Q�把sqlMapConfig.xml中在settings里配�|�的defaultStatementTimeout��L��可以避免了。但是，�q�个配置对PSQL应该OK啊。。。待�?br />
【箋�?#8212;—

defaultStatementTimeout ��实不是所有的driver都支持的�?br />但去掉的话，TimesTen又不�q�了�Q�太囧了。。�?br />

[TimesTen][TimesTen 7.0.5.9.0 CLIENT]Query Timeout must be numeric; if the Network Timeout

is non-zero, the Query Timeout must be greater than zero and less than the Network Timeout, else if the Network Timeout is zero, the Query Timeout must be greater than or equal to zero.
兜兜转�{又遇��C��q�个之前遇到�q�的问题。这些driver��׃��能统一�l�一咩！

parseInt(String s, int radix)

Parses the string argument as a signed integer in the radix specified by the second argument.

今儿头回用，真是……反省ing

Web Service Internationalization

cerulean — Wed, 15 Jun 2011 08:49:00 GMT

i18n�Q�之前在J2EE里，自然用struts来做。但是Web Service里貌似应该不需要这部分�Q�但是实际上�Q�有些操作还是避免不了要支持多国语言�?br />查了一圈儿�Q�好像WS-i18n�q�在working draft的阶�D�，而且好像已经好几�q�了……也没扑ֈ�什么开源中间�g的实现�?br />大意是在SOAP header中加�?lt;i18n:international>相关的标�{��?br />因�ؓ毕竟是Web Service�Q�利用http header�q�是不太妥，�q�是要放在SOAP里面�?br />
记录一下查到的链接�Q�备用�?br />

http://www.coderanch.com/t/224875/Web-Services/java/Web-Services-Internationalization-jax-ws

For a SOAP web service the language/country code should be part of the SOAP request and possibly the SOAP response. You can always base your solution on the above WS-I18N working draft.
Internationalization isn't as big a priority with SOAP web services as it is with web pages as web services are consumed by other applications - not humans. In most cases normalized "generic data" is exchanged which is displayed on the client using the client's locale. SOAP web services exchanging localized text are pretty much in the minority.

ConcurrentModificationException

cerulean — Fri, 11 Jun 2010 05:57:00 GMT

遍历集合�Q�批量删除时�Q�遇到ConcurrentModificationException
因�ؓ操作的集合会在过�E�中遇到�l�构性的改变�Q�例如：

HashMap<String, String> testMap = new HashMap<String, String>();
        testMap.put("1", "a");
        testMap.put("2", "b");
        testMap.put("3", "c");
        Set<Map.Entry<String,String>> enterySet = testMap.entrySet();


        for(Iterator<Map.Entry<String, String>> i = enterySet.iterator(); i.hasNext();){
            Map.Entry<String, String> entry = i.next();
            if(entry.getValue().equalsIgnoreCase("a")){
                testMap.remove(entry.getKey());
            }
        }

解决�Ҏ(gu��)��Q�不要在集合上删除，而是在�P代器上删除：i.remove();

p.s.�q�有另外一个可能性是多线�E�同时操作该集合了，那需要进行同步来避免�?
