copied!<p>I would suggest writing beans by hand, and only annotating with JAXB annotations if you have to. For most accessors/mutators (getters/setters) you do not have to; by default all public bean accessors and fields are considered, name is derived using bean convention, and default is to use elements instead of attributes (so attributes need to be annotated).</p> <p>Alternatively you can of course write schema by hand, generate beans using JAXB, if you like W3C Schema a lot. And just use resulting code, not schema, for data binding.</p> <p>As to POJO: that can be very simple. Something like:</p> <pre><code>@XmlRootElement("Response") class Response { public int responseCode; public String responseMessage; public String token; // or perhaps byte[] works for automated base64? } </code></pre> <p>and similarly for other ones. Or, use getters/setters if you like them and don't mind bit more verbosity. These are just data containers, no need to get too fancy.</p> <p>And if you must auto-detect type from content, consider using Stax parser to see what the root element, and then bind using JAXB Unmarshaller, handing XMLStreamReader that points to that root element. That way you can pass different object type to bind to.</p> <p>And finally: sending/receiving requests: plain old HttpURLConnection works ok for GET and POST requests (construct using, say, URL.openConnection()). Jakarta HttpClient has more features if need be. So oftentimes you don't really need a separate REST client -- they may come in handy, but generally build on simple http client pieces.</p>
