No. The META-INF/services.xml file is already in the .aar file, and it determines what security will be done on the *server*.
The file I'm talking about is used on the *client*. The security for both sides needs to match, or you'll get a mismatch error.
You'd use the client-side file name as value for the "axis2.xml" property that you pass to the client. (That's assuming that you're using Axis2 on the client side as well. If you're using some other client
SOAP framework, then you need to consult its documentation for how to set its security options.)
