Java (Meta)DataAdapters

limeni

Hello!

We have (meta)data adapters coded in Java, but we want to put them behind the second firewall. Is there Java's equivalent to C#'s DataProviderServer? Or the only way is to implement ARI protocol in Java?

Regards,

Indeed, there is no support for java remote adapters other than the ARI interface.
If you have any messaging middleware available, you may find it useful to see the included DOCS-SDKs\sdk_adapter_java\examples\StockListDemo_JMS_DataAdapter example.

Did I understand well: ARI over JMS? Can we use messaging middleware for communication between proxy and remote (java) adapter? Or only TCP sockets or local pipes can be used?

Alessandro Alinone

No, Dario was referring to JMS as an alternative to ARI.

ARI includes a proxy Adapter that exports the Adapter interfaces over TCP sockets.

But nothing prevents from having a proxy Adapter that exports similar interfaces over JMS. Actually, the path mentioned by Dario points to an example that shows a simple JMS Proxy Adapter.

Hope that helps.

Now I understand, thanks for help!

Hi,

Just wondering if you implemented the Javasolution using an external server (external to the lightstreamer server) - similar to the .NET sockets example described in http://cometdaily.com/2008/04/14/hel...ightstreamer/ ?

I want to implement a something similar (except in Java) and any help would be much appreciated :Smile_Ab:

Thanks,

Hi,

I'm sorry but the situation is still the same as in last Alessandro's post.
