=========================================================

2009.11.19 在另一机器上测试时，报错：

服务器出现意外情况。 (异常来自 HRESULT:0x80010105 (RPC_E_SERVERFAULT))

==========================================================

后来把下面这句注释了

//IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)serverContext.CreateObject("esriDataSourcesFile.CadWorkspaceFactory");

同时改为下面的形式

//Create a WorkspaceName object
IWorkspaceName pWorkspaceName = new WorkspaceNameClass();
pWorkspaceName.WorkspaceFactoryProgID = "esriDataSourcesFile.CadWorkspaceFactory";
pWorkspaceName.PathName = path;
IWorkspaceFactory workspaceFactory = pWorkspaceName.WorkspaceFactory as IWorkspaceFactory;

感觉问题还是AE下开发serverContext.CreateObject和new的问题。
