Trying to read JSON using Jackson in TomEE
I am having a problem with Jackson and JAXB under Apache TomEE 1.6.
The Service class implements a JAX-RS resource with path /test.
The following method works as expected:
@GET
@Produces(MediaType.APPLICATION_JSON)
public UserBean read() {
UserBean userBean = new UserBean();
userBean.setFirstName("first");
userBean.setLastName("last");
return userBean;
}
Producing the following output:
{"firstName":"first","lastName":"last"}
However, this method never executes:
@POST
@Consumes(MediaType.APPLICATION_JSON)
public String create(UserBean userBean) {
System.out.println("userBean="+userBean);
return "success";
}
The following JS code in createUser.html is used to pass JSON to the Service
class.
user = {};
user.firstName = document.getElementById('firstName').value;
user.lastName = document.getElementById('lastName').value;
// Submit the form in the background
var oReq = new XMLHttpRequest();
oReq.onload = reqListener;
url = "http://localhost:8080/tomee-jackson-test/test";
oReq.open("post", url, true);
oReq.setRequestHeader("Content-type", "application/json");
oReq.send(JSON.stringify(user));
The JS execution completes, but the println in the Service class does not
execute, nor are any exceptions thrown.
I have uploaded my test project here:
https://github.com/fulltruth/tomee-jackson-test
I read this post:
http://openejb.979440.n4.nabble.com/JSON-serialization-td4662163.html, but
that only covers writing JSON, not reading like I am attempting to do here.
Am I doing something wrong, or is this not supported in TomEE?

form data uses @FormParam no?
btw the error you got should really have printed an error in logs, you
can check it on trunk if you have doubts on 1.6.0 but maybe something
is not well configured elsewhere

OK, turns out it was my testing that was the problem. The Javascript I was
using just didn't work for post, at all. Not sure why. Anyway, I
downloaded a REST client and you're right, everything works fine. Thanks
for testing my code, that was a big help!

Romain,
Thanks for trying it out. I built the snapshot from svn, started it up, and
deployed my test, but got the same result as before.
I am using Eclipse to deploy my project into TomEE. Do you have any ideas
of what I might be doing wrong?
Also, what might I put into logging.properties to see what is happening?

PS: just tested your sample on trunk (should be the same on 1.6.0) and
it works very well ;)
are you sure you have no exception? maybe you just conflict between
jaxrs servlet and html? maybe define an Application with an
ApplicationPath or configure tomee to let createUser.html be handled
by default servlet and not jaxrs one

It's odd that it would come over as a query param. Can you check the
actual HTTP request your client is making?

Re: Trying to read JSON using Jackson in TomEE
Posted by fulltruth <dl...@gmail.com>.
If I take out this line:
@Consumes(MediaType.APPLICATION_JSON)
...don't set Content-Type on the AJAX call, and change the createUser method
to this:
public String createUser(@QueryParam("user") String userJSON) {
try {
ObjectMapper mapper = new ObjectMapper();
User userBean = mapper.readValue(userJSON, User.class);
This works just fine. So Jackson can convert from JSON to the User class
without any annotations. What I want is for TomEE to call Jackson and do
this automatically.
