XML deserialization to POJO using Jackson XmlMapper

Your POJO classes do not fit to your XML. The structure is simpler than you thought. See below example:

@JacksonXmlRootElement(localName = "open")class OpenCredentials {    @JacksonXmlProperty(localName = "creds")    @JacksonXmlElementWrapper(useWrapping = false)    private Credentials[] credentials;    //getters, setters, toString}class Credentials {    @JacksonXmlProperty(isAttribute = true)    private String priv;    @JacksonXmlProperty(isAttribute = true)    private String type;    private String user;    @JacksonXmlProperty(localName = "client_token")    private String clientToken;    @JacksonXmlProperty(localName = "client_secret")    private String clientSecret;    //getters, setters, toString}

Simple usage:

XmlMapper mapper = new XmlMapper();OpenCredentials openCredentials = mapper.readValue(XML, OpenCredentials.class);System.out.println(openCredentials);

Above program prints (for your XML):

OpenCredentials{credentials=[Credentials{priv='write', type='internal', user='Username1', client_token='abcplaudzrbcy37c', client_secret='0cxDE3LE0000='}, Credentials{priv='read', type='internal', user='Username1', client_token='123plaudzrbcy37c', client_secret='0cxDE3LE1234='}, Credentials{priv='none', type='internal', user='Username1', client_token='000plaudzrbcy37c', client_secret='0cxDE3LEabcd='}]}
