原文如下：
Dear sir:
First, let me introduce myself to you. I am a Chinese college student from Beijing. My English is not very well, but I have tried my best to make this letter to be more understandable.
I have downloaded the MapXtreme2004 v6.2 from your website www.mapinfo.com. I think it is the best GIS component for dotnet. I love it very much and I have explored many features of it.
But I came across a relatively difficult QUESTION. I can use it to connect to Oracle Spatial at Windows Application in Winform. But I can not use it to connect to Oracle Spatial at the asp.net web application.
The main SOURCE CODE is listed here:
MIConnection Connection=new MIConnection();
Connection.Open();
string connectionInfo = "SRVR=orcl_gissrv;UID=system;PWD=gis";
string tableName = "school";
TableInfoServer tis=new TableInfoServer( tableName,connectionInfo,"select * from "+tableName,MapInfo.Data.ServerToolkit.Oci);
MapInfo.Data.Table table=Connection.Catalog.OpenTable(tis);
MapControl1.Map.Load(new MapInfo.Mapping.MapTableLoader(table));
Connection.Close();
First I want to say that the Connection String is right. I have used the same code in the WinForm Application and it works perfectly. But I can not use it in the asp.net Web Application. The debug information is like this:
Unable to open table.: Data access driver requested is not available: ORAINET.
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。
I do not know the reason why it can not works well. Can you give me a detailed instruction? My E-Mail: ***@sohu.com.
I eagerly expect the reply from you.
Yours
Sincerely.

我去了一看，关于mxt2004的资料还真多（以前下载过全部的faq，也全部看了，但看到这里有这么多信息，还是吃了一惊）。就search了一下：oracle，乖乖，312条！可真把我乐坏了。这坚定了我mxt2004+oracle+.net的信心）在国内，一条都没有。（我天天在网上找oracle+mxt2004的资料，一条信息都没有找到过）。我一条一条啃，终于找到了解决方案。原文太长，贴上url:
