How get data from Angular to Core JSP?
-1
I got null value in JSP when I try to send data from angular service
export class AllService {
url: any;
cpHeaders = new Headers({ 'Content-Type': 'application/json' });
options = new RequestOptions({ headers: this.cpHeaders });
constructor(private _http: Http) { }
register(data){
console.log(data);
return
this._http.post('http://localhost:8080/client_api/register.jsp',data)
.pipe(map((res: Response)=>{ return res.json()}));
}
This is my angular service, I have to read data in jsp page
<%@ page import ="java.sql.*" %>
<%@ page import ="javax.sql.*" %>
<%
String name=request.getParameter("name");
String email=request.getParameter("email");
String mobile=request.getParameter("mobile");
String password=request.getParameter("password");
String address=request.getParameter("address");
out.println(name);
out.println(email);
out.println(mobile);
out.println(password);
out.println(address);
%>
It returns null value

You have you printed the data before sending it to JSP, Does it has all the values or the value you are expecting?

why on earth a JSP? This is way easier with say Resteasy or the like. Have you checked parameters passed to JSP?

Your Angular code sends your data as a JSON object within the request body, but your JSP code expects url-encoded body content.
You can change request body format by turning second argument of _http.post into HttpParams instance and setting correct request header like this:
import { HttpClient, HttpParams, HttpHeaders } from '@angular/common/http';
...
this._http.post(
'/client_api/register.jsp',
new HttpParams({ fromObject: data }),
{headers: new HttpHeaders().set('Content-Type', 'application/x-www-form-urlencoded')}
).pipe(map((res: Response)=>{ return res.json()}));
