请问：有用 ECO 成功开发 WebService 的高人没？

[gcx_zw1027]

我在使用　Delphi 2005（SP2）开发 ECO WebService 中遇到一个问题。那就是创建 EcoSpace 时始终会出错。
据我跟踪发现，错误始终出在虚拟类 EcoSpaceProvider 的下面一行：
return GetStrategyhandler().GetSessionFreeEcoSpace() as lsdnEcoSpace;
在调用 GetSessionFreeEcoSpace() 时始终出错。即使是新建一个项目，随便写一个函数新建一个 EcoSpace 也一样照错不误。

我怀疑这是不是 Delphi 2005 的问题，因为无论我使用 Delphi 还是 C#Builder 的哪一个，不管怎么调，都是一样的问题，我也无法跟踪进函数的内部，查不到深入的原因。

实在是非常的无奈，我觉得 Eco 是非常不错的框架，但使用起来却始终毛病不断，同一个项目我重做了N多遍，耗费了大量的时间，而且也无法查到相关文档，真是可惜了。

望高手指教。

用过DELPHI7调用WebService成功，没用过2005

给段代码
//调用
function Tf_dm.DoDeepID(iYear, iMonth: integer): Boolean;
var
L: LeagueManage;
Addr: string;
begin
Result := False;
Addr := 'http://'+ ServerIP +':' + ServerPort + '/services/LeagueManage';
L := GetLeagueManage(False,Addr,Nil);
Result := L.computeDeep(iYear,iMonth);
end;

//对应Unit
unit LeagueManage1;

interface

uses InvokeRegistry, SOAPHTTPClient, Types, XSBuiltIns;
