我有CORBA一个简单的计算C ++ / Java应用程序。 服务器用C ++编写,客户端在Java中。 我用omniORBs omniNames,如名称服务。
我想在我的本地(Ubuntu的)运行我omniNames和服务器上的Windows XP SP3安装在我的本地Ubuntu的运行我的客户在VirtualBox中。
(我的意思是:在我的本地我已经安装了Ubuntu操作系统,在Ubuntu我与Windows XP SP3“内部”安装VirtuaBox。)
我终于做到了,并设置host-only
optinon在VirtualBox中与此帮助: https://superuser.com/questions/429405/how-can-i-get-virtualbox-to-run-with-a-hosts-only -adapter话题。 现在我有一些其他的问题。 我的客户终于看到我的服务器,甚至可以连接到它,并给他发个消息,但它有问题,从服务器接收答案:(这段时间我的应用程序是一个简单的计算):

其中192.168.56.1是VirtualBox的唯一主机的IP地址。 请帮助:)在我这里张贴的例子中,从服务器的答案应该是8(因为大家都知道2 * 4 = 8;)
OK啦,对不起,打扰你们:)我找到了答案:我添加这些行到我/etc/network/interfaces
文件:
allow-hotplug eth0
iface eth0 inet dhcp
