java中的关键字（transient）
transient这个关键字并不常见，主要应用在java的序列化方面。这里我再多说，转一篇老外的文章，很生动，欣赏吧
Be Careful With Transient Data
Java's serialization provides an elegant, and easy to use mechanism for making an object's state persistent. While controlling object serialization, we might have a particular object data member that we do not want the serialization mechanism to save.
To turn off serialization on a certain field of an object, we tag that field of the class of our object with the Java's "transient" keyword. This, to low-level parts of the Java virtual machine, is an indication that the transient variable is not part of the persistent state of an object.
First, let's have some backgrounder code with Java's serialization.
Suppose we define a class as:
public class LoggingInfo implements java.io.Serializable
{
private Date loggingDate = new Date();
private String uid;
private transient String pwd;
LoggingInfo(String user, String password)
{
uid = user;
pwd = password;
}
public String toString()
{
String password=null;
if(pwd == null)
{
password = "NOT SET";
}
else
{
password = pwd;
}
return "logon info: \n " + "user: " + uid +
"\n

我们在jsp页面上的js脚本中可以调研java代码，比如，我们需要再js中用alert函数显示服务器端发送过来的某个字符串那么我们可以这样做
tomcat下：
在服务器端我们有request.setAttribute("name","abc");
那么我要在页面上用alert显示的话，有两种方式：
1、使用EL表达式
在El表达式的外面用引号即可：

最近需要制作java desktop application的安装程序。
好不容易在网上down了个installanywhere9安装并破解， 用起来还挺顺利，功能比较强大，许多地方可以定制，当然做出来的程序在安装时也随处可见installanywhere的身影，商业软件嘛！没办法。
