Capturing SOAP message on localhost using Fiddler

Question

I am unable to capture local HTTP traffic when my Java client makes a SOAP request to my local Tomcat instance.

My current configuration is

Tomcat instance - run on localhost:8080
Local Java client - run from Windows cmd line
Fiddler - run on localhost:8888

I used Axis2 wsdl2java to create my client SOAP stub, and used my machines IP address when specifying the WSDL (hosted on Tomcat)

wsdl2java -uri http://192.168.0.5:8080/axis2/services/Version?wsdl -p sample.axisversion -d adb -s

So, the generated code has lines like this throughout:

  public VersionStub(org.apache.axis2.context.ConfigurationContext configurationContext) throws org.apache.axis2.AxisFault {
    this(configurationContext,"http://192.168.0.5:8080/axis2/services/Version.VersionHttpSoap12Endpoint/" );
}

My client app uses the generated stub and I set the Java proxy to Fiddler using the following code (which gets called before the SOAP stub is actually used):

System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", "localhost");
System.getProperties().put("proxyPort", "8888");

...but still I don't see any request or response traffic in Fiddler. What's missing?

How does your code reference the service? Does it use 192.168.0.5 or does it use 127.0.0.1? Does Fiddler capture it if you use a remote hostname or IP? You might try the steps here: fiddler2.com/fiddler/help/hookup.asp#Q-JavaTraffic — EricLaw
Since the wsdl2java tool is provided with the parameter 192.168.0.5, it uses this address in the client stubs that are generated. — Jack

Instead of localhost, try to use ipv4.fiddler, which makes sure your localhost traffic goes through fiddler. See also: http://www.fiddler2.com/Fiddler/Help/hookup.asp#Q-LocalTraffic
