I want to check if session exists or not in java application. So I am calling the servlet from Angular, but it is saying null pointer exception, that means even though I am logged in in the java application, when I call the servlet from Angular, it says 'null' for session variable, HtttpSession session = request.getSession(false); I am going fromjava application to Angular application, from Angular I am calling java servlet to check if session exists, if it exists, it will directly login in Angular app, otherwise login page of Angular.

[@codingboot455]

A session id is generated in back-end and travel though request/response when sending request from browser . In angular making call through http api which doesn't track session, thats why getting null. Session is not used to track user in back-end api ,
token concept is used for authentication/authorisation in api

Hii bro i am trying to send post request to java servlet . servlet runs but servlet dont recieve any parameters. But if i try to send parameters like ?user="Abc"?pass="1234" . it works...! how to fix it..

[@codingboot455]

Are you making ajax call ? Are you extending your servlet class from HttpServlet ?
If Extending from HttpServlet then post(..) method will be called .
If making ajax call please make sure your are specifying request method as post.
