Routing Service Socket Adapter in java

I have modified the rti provided example in java of simplefileadapter in routing service for socket to dds communication.

My problem is that

In NotificationThread StreamReaderListener object is not invoking read function on line

listener.onDataAvailable(reader);

i have attached source code plz have a look on this. When i am running this adapter it is creating stream reader and also calling notification thread but when i am sending data on socket port it is not calling read function.

Hi sujeets77,

Could you run RoutingService with -verbosity 3 and post the output?

Hi Sujeets77,

From the RS log I can deduce that your Route is not running. This means that it probably has not received the type information. You want to make sure that these types are available in both the input and output, and you can provide that by using XML or through discovery (see User's manual configuration section for details on how to do this).

Also you need to make sure that the stream/topic names match the ones of your publisher and subscriber application. 

Once both conditions above are met, you should see a log from RS that will look like this:

DL Notice:  [socketdds::session::route] route running

That means your route is ready to forward data. In that case, you need to make sure data is being published from the corresponding communication side.

Thank you very much for your help.

I have defined the types structure in same socket_dds.xml file, did you mean that routing service will publish only those topic which have any subscriber application expecting that topic, i dont think so.

Hi Sujeets,

Yes in your current setup you will need to create a DDS subscriber so it can receive the information through Routing Service from your publishing socket.
