有一个java写的服务器代码，在eclipse怎么让它运行起来？这个软件完全不会用啊
这样：
打开eclipse,点击file -- new -- java project会弹出一窗口，project name 文本框里填上 test,--- 点击finsh --然后点击左边刚建立的test----new --- class ---会弹出一个窗口---name文本框里填上: ChatServer --- finsh ---然后会生成一个类，你把右边对话框里刚生成的public class ChatServer {
}
这些代码删掉，然后把你的那些代码粘贴到那对话框中，然后你将鼠标放在该对话框中右击，--》 Run AS ---- java application
这样应该没问题了
Java Web服务器
我现写了一个，可以访问到静态资源。你看情况多给点分吧
另外eclipse还没有5.5，5.5的貌似是myEclipse吧
其中port指端口，默认是地址是
其中basePath指资源根路径，默认是d:
可以通过命令行参数对其进行赋值
