If you are using Jersey for REST API's you can do as below

You don't have to change your webservices implementation.

I will explain for Jersey 2.x

1) First add a ResponseFilter as shown below

import java.io.IOException;

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;

public class CorsResponseFilter implements ContainerResponseFilter {

@Override
public void filter(ContainerRequestContext requestContext,   ContainerResponseContext responseContext)
    throws IOException {
        responseContext.getHeaders().add("Access-Control-Allow-Origin","*");
        responseContext.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");

  }
}

2) then in the web.xml , in the jersey servlet declaration add the below

    
        jersey.config.server.provider.classnames
        YOUR PACKAGE.CorsResponseFilter
