由于我已经为Eclipse下载了全新安装,因此无法启动.出现错误消息"发生错误请参阅日志文件/Applications/eclipse/configuration/1323191649568.log."
在重新安装之前,我已经多次删除了有关Eclipse和Java Runtime的所有文件和文件夹.而且,命令./eclipse -clean给了我同样的错误.
任何的想法？

当我首先执行服务器（发送）时，它会使用 ServerSocket.accept 方法等待客户端连接。问题在于，如果服务器没有先执行，客户端（接收）就无法执行。我想添加一个条件以允许客户端等待来自服务器的连接。是否可以？
发送（服务器）
ServerSocket servsock = new ServerSocket(1234);
Socket sock = servsock.accept();
接收（客户端）
Socket sock = new Socket(from, 1234);
错误（客户端）

谢谢。
我在Mac OS X Lion上运行MAMP Pro 2.0.5并且MySQL服务器无法启动.
我尝试启动时收到以下错误消息:
MySQL wasn't able to start. Please check log for more information.
我已经尝试杀死mysqld进程,但它仍然无法正常工作.
我也尝试修改/Applications/MAMP/tmp/mysql/my.cnf文件,但一切似乎都没问题.
我将不胜感激任何帮助.
谢谢.
