Its just a namespace. Take a look at EntityResolver to get a better
idea. Seems like you are trying to get an existing one - via get -
instead of creating one yourself as would be expected when using
localhost. Use the SOAPMonitor applet to what it typically is - for
security work you often create your own as a marker such as
"http://schemas.xmlsoap.org/soap/envelope/" . So you'll get null if it
doesn't exist, so use a tool to sniff out the value. Keep in mind
though it may indeed not exist at all unless you create it yourself.
