最近赋闲，借来这本书看。本来希望很大，期冀可以学到些东西。结果，事与愿违。

总的感觉：这书一般，不推荐给大家，尤其是对于有项目开发经验的人。在这个200多页的书里，作者罗列了项目开发方法，开发工具，开发环境等等。因为涉及内容太多，所以每个知识点都是一带而过，不过讲讲优点，缺点。所以感觉四不像。

如果你是个没有项目开发经验的人，想全面地了解目前web开发的基本过程，项目可能涉及的技术方面，可以看看。


下面是自己的一些读书笔记，你们可以掠过：

1.Agile model driven development(AMDD): focus on model

2.Extreme programmning: focus on full development life cycle.

3.Jconsole: c:\program files\java\jdk1.6.0_14\bin\jconsole, which could dectect the memory issue, class loading,

garbage collection...
 

Java profilers: analyze the heap for memory usage and leaks, CPU utilization, trace object and methods,determine performance bottlenecks...

4.Ant new feature:

      <exec command="date"/>

   Get:  fetch a file using HTTP GET.

      <get src="http://visualpatterns.com/comics/funny.gif" dest="funny.gif"  verbose="true"/>

   Sleep: pause processing.
 
 <sleep seconds="2"/>
 
   FTP: use FTP directly. The example transfe the files to ftp server automatically using windows scheduled tasks
 <ftp server="mirror.kernel.org"
      action="get"
      remotedir=...> </ftp>

   MAIL: ...

5. JMX: my thought: I can use it to track how many user signed into, and so on.

6.unchecked exception: do not need to be caught by the code. Checked exception require the code to either cathch the exception or throw it up the call chain using throws. "If  a client can reasonble to recover from an exception, make it a checked exception. If client cannot do anything to recover from the excepetion, make it unchecked"
