**** UnicuteChat Load-Balancing Test ****

************************************

In Internet Explore 7.0 of client machine we digit HTTP-URL:

http://localhost/unicutechat/Chat.aspx

obtaining error:

general error message:

                “Unable to get portal instance because current application is not cutechat server.”

 

detailed exception-error message:

                “System.Exception: Unable to get portal instance because current application is not cutechat server.”

 

source-code error message in file:

Source File: “c:"Inetpub"wwwroot"UniCuteChat"chat.aspx”   

Row Number: “55”

Row Code: “foreach(LobbyInfo lobby in ChatApi.GetLobbyInfoArray())”

*****************

**** Questions ****

*****************

What do you think about the installation and configuration? Something has wrong?
About load-balancing documentation, for server side installation, what does it mean “Deploy cute chat/messenger to the server which is running in single-process mode”?

Angelo
 

I'm get same your problem!
so any solution from Cutesoft?
my system : 3 web server (IIS) loadbalancing + 1 MSSQL DB server.
I'm deploy using this manual : http://cutesoft.net/ASP.NET+Chat/Developer-Guide/scr/Load-Balancing.htm
when i'm run NLBservice from any server i'm get error :

Missing Header CuteChat.NLB=1
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Exception: Missing Header CuteChat.NLB=1

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 

Stack Trace:


[Exception: Missing Header CuteChat.NLB=1]
   CuteChat.ChatNLBServiceHandler.ProcessRequest(HttpContext context) +1025
   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +358
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

 

so, how about Grouplist.aspx ?

I see it used :

string GetForumChatterNames(object forumid)
    {
        string key="Forum:"+forumid;
   
        foreach(LobbyInfo info in ChatApi.GetLobbyInfoArray())
        {
            if(info.Lobby.Integration==key)
                return info.JoinClient(",");
        }
        return "";
    }
    int GetForumChatterCount(object forumid)
    {
        string key="Forum:"+forumid;
        foreach(LobbyInfo info in ChatApi.GetLobbyInfoArray())
        {
            if(info.Lobby.Integration==key)
                return info.ClientCount;
        }
        return 0;
    }

Hi all,

 

the ChatApi.GetLobbyInfoArray is an obsoleted method because it's not compatible with the load balancing feature.

The file is dated 23/02/2009, the file version is 5.0.0.0, but I can't find the build date anywhere in file properties.
