cd ..\data
 //数据库文件会放到这个目录，如果不存在hsqldb会自动创建
java -cp ../lib/hsqldb.jar org.hsqldb.Server -database.0 file:mydb -dbname.0 xdb 
//-database.0 file:mydb 数据库文件的名字，-dbname.0 xdb 数据库的名称


连接到hsqldb:
DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/xdb", "sa", "");
// "hsql:host" 是通过网络连接，还有"file:file_path"是在当前jvm使用hsqldb引擎并使用指定数据库文件，"mem:name"是用内存数据库
//"xdb"是刚才设置的数据库名称
//一般新建的数据库，hsqldb应该都是创建一个用户名是"sa"，密码是空的管理员账号

The first is to set it on the command line:
> java -Duser.language=2-char-language-code -Duser.region=2-char-country-code MyApp

// Set only language code
> java -Duser.language=en -Duser.region= MyApp
// Set language and country code
> java -Duser.language=en -Duser.region=US MyApp

The second way to change the default locale is to call Locale.setDefault():
// Get default locale
Locale locale = Locale.getDefault();

// Set the default locale to pre-defined locale
Locale.setDefault(Locale.US);

// Set the default locale to custom locale
locale = new Locale("en", "US");
Locale.setDefault(locale);

1.创建一个只含有<html></html>的空白htm页面，把iframe的src属性赋值为该空白页面。
elmIfr = document.createElement("IFRAME"); elmIfr.scr="blank.html";
document.body.appendChild(elmIfr);
 

2.src = "javascript:void(0)". is working in IE and Firefox
 

3.In IE6 and Firefox, this could be fixed by src="spacer.gif" and put spacer.gif at your root. Once this image is cached at the browser and browser would not request this image and it should work irrespective of protocol.


4.src = "javascript:''", is working in IE6 SP2
