When issuing SOAP requests sometimes (for example when firing them from your custom created application) you are interested in how they look like, if the fields are all set and with the correct values.
One approache is to see them in Fiddler but by default Fiddler does not integrate with SoapUI so it doesn’t catch them.
To do that you need to configure SoapUI with Fiddler as proxy. Open Fiddler and find the port which it uses. In my case, and by default, it uses port 8888. Next step is to open SoapUI, go to File->Preferences->Proxy Settings. In the new screen select the Manual radio button, fill Host with 127.0.0.1 and port 8888.
That’s it. Now you can see your Soap request in Fiddler.
