- Nightmare: Java Applet and JavaScript - 2006-10-18 00:21
I met the same thing about 2 years ago. And many of my JavaScript calls?were restricted according to the sanbox of Java Applet, so calls needed to be asynchronized. But my JavaScript calls should be?s ... - 关于内部类 - 2006-07-07 15:43
挺有意思的是，我非常支持这些语法！ 首先Eclipse JDT提供的"content assist"能够非常快速的完成上述代码； 其次Eclipse JDT提供的Java编辑器也能够非常有效地实现阅读其中的代码结构（包括内部类对外部类的属性以及方法的引用关系）； 还有编译出来的Java字节码不会因为内部类而有性能上的损失； 如果不用这些内部类，你需要花更多的时间处理传递对象和属性值； 要不尝试一 ... - JavaEE 5技术特性 - 2005-08-16 09:38
美国当地时间8月8日，Java企业版（Java EE，即以前的J2EE）第5版总体技术规范（JSR-244，http://jcp.org/en/jsr/detail?id=244）通过了JCP执行委员会的公开审查投票。 JSR-244规定了Java EE 5总体框架下需要具备的技术特性，其中的各项技术又分别由其他JSR所规定。从提交公开审查的规范草案Java EE 5的来看，Java EE 5的 ... - URI's UTF8 to GB* - 2005-08-08 15:22

从Java Applet载入到Applet.start()需要一段时间, 而就是Applet.start()已经完成, 从浏览器访问Applet中的函数, 还会需要一段时间. 譬如说在Linux下的FireFox, 通过JavaScript访问Applet内部函数的话, 必须登上一段时间, 譬如在J2SDK1.4.2_02中需要大概850ms, 在J2SDK1.4.2_06中需要大概650ms. ... - Extract Method need-to-know - 2004-12-09 16:26
