TCPMon is a TCP monitoring tool. It allows SOAP messages travelling over HTTP between clients and Web services to be intercepted and displayed. This allows the user to see the SOAP message as it appears on the wire.
You can run TCPMON from within an OGSA-DAI binary distribution as follows:
Either run:
$ ant tcpmon
Or run:
$ setenv.sh $ java org.apache.axis.utils.tcpmon
For information on how to use TCPMon see http://ws.apache.org/axis/java/user-guide.html#AppendixUsingTheAxisTCPMonitorTcpmon.
