Java thread CVS Gmail CGI

有了上一篇的基础，在学习下skype的api, 就可以实现skype字典机器人功能了:-)

1. 下载skype java 开发包

http://cvs.sourceforge.jp/cgi-bin/viewcvs.cgi/skype.tar.gz?view=tar

2. 将tar包里release文件夹下的jar加入到build path

3. 将上一篇（读取StarDict里的字典文件）用到的jar也加到build path, 同时注意配置好config.properties

4. 使用。

用了3个类来实现，

StarDict 根据输入的单词返回翻译结果

WitRobot 与skype交互的类，监听输入消息，返回结果

Start 开启一个后台线程监听skype消息

5. 运行Start类, 然后尝试向本机的skype发送消息. 如果你启动中碰到下面的错误，请将release文件夹下的swt-win32-3232.dll放到你的jave/jre/bin目录下

java.lang.UnsatisfiedLinkError: no swt-win32-3232 in java.library.path

.....

6. 演示效果：
