问题
I encounter IllegalArgumentException while sending a post request to the restful web-service.
If i comment the method for post request(getEmplByPostReqParam()) then, code works fine for get request but with getEmplByPostReqParam(), all request throws IllegalArgumentException.
Can you please help in identifying the problem.
Web service code:
@Path("/employee")
public class EmployeeInfoService {
// This method is called if TEXT_PLAIN is request
@GET
@Path("/get/{id}")
@Produces(MediaType.APPLICATION_ATOM_XML)
public Employee getEmplById(@PathParam("id") String id) {
System.out.println("sayPlainTextHello");
EmployeeDAO dbHandler = new EmployeeDAOImpl();
Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id));
return fetchedEmployee;
}
@GET
@Path("/get")
@Produces(MediaType.APPLICATION_ATOM_XML)
public Employee getEmplByGetReqParam(@QueryParam("param1") String id) {
System.out.println("getEmplByGetReqParam");
EmployeeDAO dbHandler = new EmployeeDAOImpl();
Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id));
return fetchedEmployee;
}
@POST
@Path("/get")
@Produces("MediaType.TEXT_PLAIN")
public String getEmplByPostReqParam(@FormParam("param1") String id) {
System.out.println("getEmplByPostReqParam");
EmployeeDAO dbHandler = new EmployeeDAOImpl();
Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id));
return fetchedEmployee.toString();
}
}
I used two client to test the service: 1. Google chrome's Advance Rest client
url - http://myhost:14443/de.vogella.jersey.first/rest/employee/get
payload - [param1: 1]
method type - [post]
core java code
String url = "http://myhost:14443/de.vogella.jersey.first/rest/employee/get"; String charset = "UTF-8"; String param1 = "1"; String query = String.format("param1=%s", URLEncoder.encode(param1, charset)); URL service = new URL(url); URLConnection connection = service.openConnection(); connection.setDoOutput(true); // Triggers POST. connection.setRequestProperty("Accept-Charset", charset); connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset); OutputStream output = connection.getOutputStream(); try { output.write(query.getBytes(charset)); } catch (Exception e) { // TODO: handle exception }

回答1:
I resolved the issue by changing the getEmplByPostReqParam() as follows:
@POST
@Path("/get")
public Response getEmplByPostReqParam(@FormParam("param1") String id) {
System.out.println("getEmplByPostReqParam");
EmployeeDAO dbHandler = new EmployeeDAOImpl();
Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id));
ResponseBuilder rb = new ResponseBuilderImpl();
rb.type(MediaType.APPLICATION_ATOM_XML);
rb.entity(fetchedEmployee);
return rb.build();
}
This is working fine for me, if their is some better approach or their is something wrong with this approach, please post comment.

If you notice your annotation (@Produces) argument is passed in double quotes. remove the double quotes and it should work
@Produces("MediaType.TEXT_PLAIN")
should look like below
@Produces(MediaType.TEXT_PLAIN)
