Send a request using the Stock Quote client to WSO2 ESB in the following manner. For information about the Stock Quote client, refer to section Sample Clients in the WSO2 ESB documentation.
ant

stockquote

-Daddurl=http://localhost:9000/services/SimpleStockQuoteService
...
-Dtrpurl=http://localhost:8280
Note that the message mediates though main, seq1 and sendSeq before reaching the endpoint. Each sequence adds a property to the message, and the final Log mediator at sendSeq puts out those properties as follows:
INFO
...
-
...
LogMediator
...
mainSeq
...
=
...
**
...
At
...
Main
...
Sequence**,
...
seq1
...
=
...
***
...
At
...
Sequence
...
1
...
***,
...
sendSeq
...
=
...
***
...
At
...
Sequence
...
1
...
***
Similarly, you can add required entries to a message to track and display its mediation history.
