Hi everybody.
I have a problem with axis2 (1.4.1) and rampart (1.3).
I put a simple policy in services.xml [1] and I wrote a
PasswordHandler [2]. Everything works fine if user and password are
correct. When the user doesn't exist (getUser returns
UserNotFoundException), the authentication process (correctly) fails,
but returning a HTML error page [5] instead of a SOAP response
message. The servlet engine logs an error message coming from the Axis
Servlet [4], and the SOAP client, that uses a library generated by
WSDL2Java, logs the error "First Element must contain the local name,
Envelope , but found html" [3].
I want to return to the client a custom SOAP error message if
authentication process fails. How can I do it?
Thanks,
Giuseppe

pwcb.setPassword(password);
} else {
throw new
UnsupportedCallbackException(callbacks[i],
"Unrecognized Callback");
}
} catch (UserNotFoundException e){
throw new AxisFault("No user found",
e.getCause());
}
}
}
}
