JAX-RS Encoding

Question

I'm using JAX-RS to create a web (rest) service that returns results in JSON format.

Everything is OK, except the encoding.

For example, I get:

 ..., parameter:"Dep\u00f3sitos" ,...

Instead of:

 ..., parameter:"Depósitos" ,...

I've tried using:

@Produces("application/json; charset=UTF-8")

but the problem remains. If I return it as XML using just:

@Produces("application/xml")

Everything is ok.

What do I need to set to produce the right type?

Can you edit your question to include the actual code of your JSON method? — Jim Ferrans, Mar 04 '11 at 06:30

All you need is this:

String back = "Depósitos";
return new String(back.getBytes(), "UTF8");

This is useless and dangerous code. `String.getBytes()` converts the string to the platform's default encoding. Let's say you are on Windows, so this might by `CP1252`. Then you create a new String object out of these bytes and tell Java the bytes have to be interpreted as `UTF-8`, even if the bytes are `CP1252` text in this example, which will lead to problems. Further: `back` is already a String, Java String objects can be seen as text without encoding (they are encoded with `UTF-16` internally, but this doesn't matter). Encodings become important only when a String is converted to bytes. – Sky Mar 06 '18 at 16:46

I ended up using GSON instead of IBM's JSON4J which proved to be much better at handling custom Java class serialization.

Take a look at Bryant Luk's answer to the question "How to set the charset with JAX-RS?" and see if it does the trick.
