EJB RESTful web service posting xml failure

Question

I have problem with POSTing xml file to web service server. I was following this tutorial: EJB WEB SERVICE TUTORIAL everything works except POSTing xml file. I am trying to do this via Poster chrome extension and get this error in JBoss console:

I was trying find solution on the internet but unfortunately nothing found.

Answer 1

It looks like you're posting a Customer List from a non structured format (text-plain). Resteasy will only be able to unmarshall from a structured format like xml,json. So your client app is the culprit in that case. If you really want to unmarshall from a String of character then you'll have to provide your own MessageBodyReader .
