#BeanParam gives exception A message body reader for Java class was not found - rest

Question

I am trying to make a jersey based web service. In this if i take input params using #FormParam it works fine:
#POST
#Consumes({MediaType.TEXT_PLAIN, MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON, MediaType.TEXT_HTML, "application/x-www-form-urlencoded"})
#Path("/registeruser")
public Response registerUser(#FormParam ("email") String email,#FormParam ("name") String name ){
System.out.println("Inside register device");
System.out.println("registered" + email);
return null;
}
but when I try using #BeanParam it does not works and gives me an exception
#POST
#Consumes({MediaType.TEXT_PLAIN, MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON, MediaType.TEXT_HTML, "application/x-www-form-urlencoded"})
#Path("/registeruser")
public Response registerUser(#BeanParam UserForm userForm ){
System.out.println("Inside register device");
service.registerUser(userForm);
System.out.println("registered" + userForm.getEmail());
return null;
}
A message body reader for Java class com.stc.dms.forms.UserForm, and Java type class com.stc.dms.forms.UserForm, and MIME media type application/octet-stream was not found.

You don't need to use #BeanParam to pass an object as input. Just pass it like this :
#POST
#Path("register")
#Consumes(MediaType.APPLICATION_JSON)
public Response registerUser(UserForm dto) {
// ...
}
Just make sure to include the libraries for producing/consuming json. If the client is in javascript you don't need anything else (just use JSON.stringify() on your form object), for the server add some json libraries such as Jackson
EDIT :
If you want to stick with #BeanParam, take a look at this tutorial here. Basically it seems that you don't need to specify the mediatype, as Jersey will handle that for you.
