WSO2 ESB Sample Service List

Question

I'm having trouble understand how WSO2 Proxy services are viewed. I went through the tutorial to create and use the SimpleStockQuotesServices proxy service, and that went just fine.

Then I shut down the ESB, and started it up with sample 0 configured (ie: ./wso2esb-samples.sh -sn 0) and that worked fine. I started the backend axis server, and that worked fine too. I ran the sample ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dprxurl=http://localhost:8280/ and it worked fine too. Everything is great.

When I go to the admin console, and look at the list of deployed services https://localhost:9443/carbon/service-mgt/index.jsp?region=region1&item=services_list_menu The page shows three services (echo, Version, and wso2carbon-sts). not the SimpleStockQuoteSercice that I was expecting. If I shut off the ESB, it all fails

My question, is, Where is it listed? I guess that the ESB is just redirecting http://localhost:9000/services/SimpleStockQuoteService to http://localhost:8280/services/SimpleStockQuoteService, but I'm not sure, and I was really expecting to see the stock quote service. What's going on?

When I ran through the tutorial, I created a SimpleStockQuoteService, and when I started up sample set zero, I assumed that it would start up a similar SimpleSTockQuoteService on the ESB.

SimpleStockQuoteSercice is deployed inside the backend axis2 server and not inside ESB. What happens here is that ESB sits in-between the client and the backend axis server, mediating the messages.

In this sample, requests are sent to the ESB (http://localhost:8280/) and the ESB then sends them to the backend axis2 service (http://localhost:9000/services/SimpleStockQuoteService). You can find more info on the parameters used for this client here.
