How to get argument passed to HTTP POST

Here is an snippet of the code that I use in my RESTful webservice. I am sending a JSON data to the create(Employee entity) method. I want to get that JSON data from the servlet request.

The System.out.println(..) method that I used gets printed which means stringBuffer is not NULL; yet nothing gets printed after ":" character [I am checking this in the glassfish logger].Besides, the POSTed enitity is being persisted to the database correctly.

I have googled many of the questions related to this on stackoverflow and other sites but nothing that I have tried works so far.

public class EmployeeFacadeREST extends AbstractFacade<Employee> {
@Context private HttpServletRequest servletRequest;
@PersistenceContext(unitName = "EmployeePU")
private EntityManager em;

public EmployeeFacadeREST() {
    super(Employee.class);
}


@POST
@Override
@Consumes({"application/xml", "application/json"})

public void create( Employee entity) {
    StringBuffer stringBuffer = null;
    try{
        InputStream body = servletRequest.getInputStream();           
        stringBuffer = new StringBuffer();
        int d;
        while((d = body.read()) != -1){
            stringBuffer.append((char)d);
        }
    }
   
    catch(IOException e){
       
    }
    if(stringBuffer != null){
        System.out.println("the entity is: " + stringBuffer.toString()); // this line gets printed
    }
    super.create(entity);
}
// more code

}

Your insight is appreciated.

The server already consumed the request body in order to de-serialize it into the Employee entity for you automatically. You can't read the same input stream again.

You need to set the 'entity' used by the POST with the value of your stringbuffer.

check the tests or samples of a jersey /glassfish POST .

The POST.entity expects the value u want in the body of the POST.
