在java的JFrame内通过创建匿名对象的方式做登录界面

//构造无参构造器把主要的方法放在构造器里,然后在main方法里面调
public LoginFrame(){

setDefaultCloseOperation(EXIT_ON_CLOSE);

建议你用jsp技术
表示层用html或jsp(DreamWare开发)
控制层用servlet
模型层用javabean
数据库你可以随便选，建议用mysql
不是很难，我用的数据库时oracle
如果你需要例子
留下邮箱给我。
静态网页一般用Html ,css 等就完成了, 不需编译直接运行。jsp可以做动态网页
本人急忙做的:有什么不合要求的请再告诉我：
