How to Design Jax - RS for two different methods with same path and producing/consuming same media type? - http-post

Question

I want to design a Post service with two methods. Method names will be different. These two methods will take different objects for invocations. But Path and Production/Consumption media types will have to be same. How to do that? Please find this code below. It is giving exception like " A resource model has ambiguous (sub-)resource method for HTTP method POST and input mime-types as defined by"#Consumes" and "#Produces" annotations at Java methods" while being deployed into weblogic.
package com.adac.rest.service;
import javax.ws.rs.Path;
import javax.ws.rs.POST;
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import com.adac.rest.model.Response;
import com.adac.rest.model.SalesData;
import com.adac.rest.model.Tax;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
#Path("/rest")
public class StageDataLoadingService {
#POST
#Path("/dataloading")
#Consumes("application/json")
#Produces("application/json")
public String resourceMethodPUTSalesData(SalesData sd) throws Exception {
System.out.println("This method called with Sales Data");
Response resp = new Response();
resp.setStatuscode("0");
resp.setStatusmessage("Success");
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
String json_resp = mapper.writeValueAsString(resp);
String str1 = mapper.writeValueAsString(sd);
System.out.println(str1);
//String sd1 = mapper.writeValueAsString(sd);
//System.out.println(sd1);
// JsonNode jsonNodeRoot = mapper.readTree(json_resp);
return json_resp;
}
#POST
#Path("/dataloading")
#Consumes("application/json")
#Produces("application/json") public String resourceMethodPUTTax(Tax tax)
throws Exception {
System.out.println("This method called with Tax");
Response resp = new Response(); resp.setStatuscode("0");
resp.setStatusmessage("Success");
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT); String json_resp =
mapper.writeValueAsString(resp);
String str1 = mapper.writeValueAsString(tax);
System.out.println(str1);
return json_resp;
}
}
Also, suggest web.xml and weblogic.xml configurations for the design you suggest.
Currently web.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>ADACStageDataLoadingService</display-name>
<servlet>
<servlet-name>rest.application.config.ApplicationConfig</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>rest.application.config.ApplicationConfig</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
and weblogic.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app
xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

When you develop the api I suggest you to follow the rest best practices:
if you want insert a resource use POST method and use the following #Path: /SalesData/{resourceId} (you can omit "dataloading" because is implicit in the POST method
if you want update a resource use PUT method with the same path: /SalesData/{resourceId}
if you want delete a resource use DELETE method
