Problem publishing using pub-sub adapter

Question

Hi,
I want to see events from my EPN in the Visualizer. For that I created an adapter that connects to a channel in side the EPN. It is a httppub adapter.
When I am trying to start it for publishing from the visualizer I get in the Eclipse (I run the CEP from the Eclipse):
<18:20:23 IST 08/12/2011> <Error> <EventInspector> <BEA-2060506> <Stage adapter cannot be configured for event tracing because it is not an event source. The stage must implement StreamSource or EventSource to be an event source.>
Isn't the adapter "automatically" publish the event? Do I need to create a bean for that?
Below the adapter config and my EPN file:
Adapter config:
<?xml version="1.0" encoding="UTF-8"?>
<wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application">
<http-pub-sub-adapter>
<name>adapter</name>
<server-context-path>/pubsub</server-context-path>
<channel>/InputChannel</channel>
<user>wlevs</user>
<password>welcome1</password>
</http-pub-sub-adapter>
</wlevs:config>

Answer 1

Sorry maybe I should have gave detailed information:
On the visualizer I opened the EPN->right click on the http pub adapter->open panel-> trace event->put the channel name->start->get a message "you are about to start event tracing"->pressOK
nothing happens the status stays OFF.
In the Eclipse (I run the server from the Eclipse) I get:
<20:44:33 IST 08/12/2011> <Error> <EventInspector> <BEA-2060506> <Stage adapter cannot be configured for event tracing because it is not an event source. The stage must implement StreamSource or EventSource to be an event source.>
When going to view strean the channel is not there.
Am I doing something wrong?
