JSP SQL SQL Server Tomcat Dreamweaver

最近的一个任务是公司试用的JSP版考试系统，感觉就是练笔用的。以前笔试的时候是.Net版本，这次是java，大同小易，不过都是让学员仿写

的而已，首先是实现读取.properties中的文件，包括了如何在tomcat上获得相对路径的方法，其中有不少波折，感觉能独立地分离出要实现的

功能进行独立的测试是最好的，然后就是糊里糊涂忙了一下午的中文编码问题和数字转字符，基本上以放弃告终。接下来是生成页面的表格行

宽控制，最后还是用dreamweaver改。晚上又让在start的时候发一封，提交的时候发2封给hr，基本参考2封给笔试人的成例写了出来。添加了

验证email格式的javascript。即将实现一个录入题库的页面。搞了老半天才搞定单form的多submit。

接着尽量完善，过程绝对是痛苦的，不知什么时候才是尽头，jacky加入了，一起研究发现原来的版本到底有多烂，看得吐血，jacky学得很好

，比我强多了，我开始反省这么久以来自己到底学了些什么，方法，方向，还有程度，都在思考，确定的是知识就是工具，而我们需要的是能

够熟练使用工具做自己想做的事。晚上吃饭，几个人聊了一下先后进来的经历，只是很零碎地谈了一些，却帮助我了解了很多他人的想法。

又过了半个星期多，包括题目录入在内的所以项目代码基本完工，简单测试了一下，确保除首页外获得的都是servlet，而由中间页submit都会

跳转回首页，相关的验证测试也基本完成，绝对交付leader了，但愿经得起他的考验吧。

读取properties
tomcat上相对路径的寻址
提交的时候发2封给hr2，2封给笔试人。
加name tel email验证
结束显示成绩，跳转到index
防止中间页渗透
start的时候发一封hr1.
.net中提交页面文字也会放大。
统计分数,修改bt的答案验证功能。
清session，不可后退
多种组合中，1，3，4，5只选junior(1)，2能选2个，6只选senior，但senior(2)
重点剩下录入题库
防止中间页访问
检查其他容错
独立的测试

directions:start from the begin
html,xml,http/tcp/ip,javascript,jsp.jstl,struts,spring,hibernate,
learn it from beginning
