The MAMA API loads the transport configuration from a file named
mama.properties
, which should reside in a directory set in the WOMBAT_PATH environment variable. An examplemama.properties
file is available insample_config/mama.properties
. The subscribing adapter'sMiddleware
andTransport
properties must match the properties set inmama.properties
.It is strongly recommended that prior to running the StreamBase application, the user has a running mamalistenc client. The configuration and environment properties set in the adapter must match the parameters for the mamalistenc client.
The sample application is named
MamaSub.sbapp
. It demonstrates receiving data from a Wombat Feed Handler and emitting the resulting tuples on an output stream. -
-
Double-click to open the sample application,
MamaSub.sbapp
. -
Double-click on MamaOutput adapter. In the Properties view, select the Adapter Properties tab. Set the middleware and transport options to match the values defined in your
mama.properties
file on WOMBAT_PATH. -
In adapter properties the source should be set to the MAMA Source on which you will receive data.
-
Click the
Run button. This opens the Test/Debug perspective and starts the application.
-
In the Test/Debug Perspective, open the Manual Input view. Enter any symbol you wish to subscribe to.
