I am using spring 4 for dependency setter injection and jersey 2 for restful web services.when I run this project on tomcat,the object is injected but when I call service layer class method using injected dependency i am getting NullPointerException.Here is jersey resource.Kindly help in this regard.
package com.mobileware.fitransxt.resource;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import com.mobileware.fitransxt.authentication.request.AuthenticationRequest;
import com.mobileware.fitransxt.authentication.response.AuthenticationResponse;
import com.mobileware.fitransxt.boimpl.AuthenticationImpl;
import com.mobileware.fitransxt.responsebuilder.Response;
import com.mobileware.fitransxt.responsebuilder.ResponseBuilder;
#Path("/auth")
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public class AuthenticationResource {
private AuthenticationImpl objAuthentication;
public AuthenticationImpl getObjAuthentication() {
return objAuthentication;
}
public void setObjAuthentication(AuthenticationImpl objAuthentication) {
System.out.println(objAuthentication);
this.objAuthentication = objAuthentication;
System.out.println(this.objAuthentication);
}
#Path("/authentication")
#POST
public Response authenticate(AuthenticationRequest objRequest) {
System.out.println(objAuthentication);
System.out.println("auth");
AuthenticationResponse objResponse = objAuthentication.authenticate(objRequest);
return ResponseBuilder.buildSuccessResponse(objResponse);
}
