If you want to examine SOAP messages sent from and received by Taverna, they are logged to taverna-x.y.z.log file in logs directory of your Taverna home directory.


You can see SOAP request and response messages in more detail by turning on DEBUG logging for theHTTPSender used by Axis. This is achieved by modifying the conf/log4j.properties in your Taverna startup directory and adding the following lines:


Bear in mind this will generate a lot of logging.

If you are a service developer using Axis and want to inspect the SOAP messages your service is sending and receiving, you might also want to check the SOAPMonitor utility provided by Axis.
