Question

我正在关注jacorb documentation的第4章中的例子。当我启动客户端时，我收到此错误

INFO Initialising ORB with ID: 
WARNING Warning - unknown codeset (MacRoman) - defaulting to ISO-8859-1
Exception in thread "main" java.lang.NoClassDefFoundError: stock/_MyServerStub
    at stock.MyServerHelper.narrow(MyServerHelper.java:62)

所以问题是_MyServerStub。当我尝试编译_MyServerStub.java时，我得到了这个错误

您需要将JacORB jar添加到类路径中。

我建议在jacorb-developer列表中询问有关JacORB的问题（http://www.jacorb.org/contact.html）

在jacorb中编译存根
