Connection reset error

gshatkin

Hello,

I developed a .NET DataAdapter following examples from both the HelloWorld and StockListDemo projects.

I configured everything correctly (I think). The LS server starts, and my proxy adapter is listening for connections. Everything runs on the localhost.

The data adapter connects successfully and then the client subscribes for items. The data adapter retrieves the data from an external source and raises the Update event.

Here, the error happens and the LS server throws. Below is the log. I cannot figure it out - would you please help me by pointing out what I am missing? Thanks in advance.

hi,

it seems that the connection between the LS server and the remote adapter is broken.
Is it possible that there are connectivity problems between the server and the adapter?

Please also check RobustNetworkedDataProvider

Mone,

Thanks for your suggestion. I used the proxy adapter you mentioned, it gets me a little further but still there is something missing.

The LS server starts fine, the Data Adapter loads fine, (I am using the default "com.lightstreamer.adapters.metadata.LiteralBasedProvider" meta data adapter).

I them start-up an external feed, which is hosted in a Console App using the StandaloneLauncher sample in the StockListDemo sample. The feed starts fine and LS shows connection established.

When I start-up a client, it connects, but then I get an exception in the StandaloneLauncher.cs, in the following code:

public bool handleException(Exception exception) {
if (! _closed) {
_log.Error("Caught exception: " + exception.Message, exception);
_server.Close();
System.Environment.Exit(1);
}
return false;
}

The exception reads: Found value '1.3605' of an unsupported type while building a UD3 request

I believe I am still missing some settings, maybe I cannot use the LiteralBasedProvider fir the meta data adapter? Please advise.

Thanks a lot,

GS

I found the issue:

In my external feed I was sending out prices as double, and LS doesn't like it. Changed it to strings and everything works fine. The following thread was helpful:

I'm glad you found the issue.
Thanks for sharing your solution.
