My WSS knowledge is a bit dated but try this:
public void handle (Callback[] callbacks) throws IOException,
UnsupportedCallbackException {
for (int i = 0; i < callbacks.length; i++) {
System.out.println("in callback number: " + i + " , usage:
" + pwcb.getUsage());
WSPasswordCallback pwcb = (WSPasswordCallback) callbacks[i];
if (pwcb.getIdentifer() == null) {
pwcb.setPassword(passWordFromDB);
} else {
System.out.println("found id, this could be used to get
the stored password from somewhere: " + pwcb.getIdentifer());
}
}
}
My read on the docs and some code examples is that you set password in
this callback:
http://wso2.org/library/3733
"So let's look at how password callback handlers work. Whenever
Rampart Engine needs a password to create a username token, whether it
is to build a signature, validate username token or decrypt an
encrypted content, it will create a WSPasswordCallback instance
setting the appropriate identifier which it extracts from the
<ramp:user> parameter of the Rampart configuration and pass it to the
password callback class via the handle method. Then password callback
fills the password relevant to the given identifier so that the
Rampart Engine can use it for further processing."
