Method Detail

validate

public Credential validate(Credential credential,
                           RequestData data)
                    throws WSSecurityException

Validate the credential argument. It must contain a non-null UsernameToken. A CallbackHandler implementation is also required to be set. If the password type is either digest or plaintext, it extracts a password from the CallbackHandler and then compares the passwords appropriately. If the password is null it queries a hook to allow the user to validate UsernameTokens of this type.

Specified by:

validate in interface Validator

Parameters:

credential - the Credential to be validated

data - the RequestData associated with the request

Returns:

a validated Credential

Throws:

WSSecurityException - on a failed validation

verifyCustomPassword

protected void verifyCustomPassword(UsernameToken usernameToken,
                                    RequestData data)
                             throws WSSecurityException

Verify a UsernameToken containing a password of some unknown (but specified) password type. It does this by querying a CallbackHandler instance to obtain a password for the given username, and then comparing it against the received password. This method currently uses the same logic as the verifyPlaintextPassword case, but it in a separate protected method to allow users to override the validation of the custom password type specific case.

Parameters:

usernameToken - The UsernameToken instance to verify

Throws:

WSSecurityException - on a failed authentication.

verifyPlaintextPassword

protected void verifyPlaintextPassword(UsernameToken usernameToken,
                                       RequestData data)
                                throws WSSecurityException

Verify a UsernameToken containing a plaintext password. It does this by querying a CallbackHandler instance to obtain a password for the given username, and then comparing it against the received password. This method currently uses the same logic as the verifyDigestPassword case, but it in a separate protected method to allow users to override the validation of the plaintext password specific case.

Parameters:

usernameToken - The UsernameToken instance to verify

Throws:

WSSecurityException - on a failed authentication.

verifyDigestPassword

protected void verifyDigestPassword(UsernameToken usernameToken,
                                    RequestData data)
                             throws WSSecurityException

Verify a UsernameToken containing a password digest. It does this by querying a CallbackHandler instance to obtain a password for the given username, and then comparing it against the received password.

Parameters:

usernameToken - The UsernameToken instance to verify

Throws:

WSSecurityException - on a failed authentication.

verifyUnknownPassword

protected void verifyUnknownPassword(UsernameToken usernameToken,
                                     RequestData data)
                              throws WSSecurityException

Verify a UsernameToken containing no password. This does nothing - but is in a separate method to allow the end-user to override validation easily.

Parameters:

usernameToken - The UsernameToken instance to verify

Throws:

WSSecurityException - on a failed authentication.
