@SanthoshKumarB7206  you can write an utility function in java

String jwt_token = "";

String token;         Calendar date = Calendar.getInstance();         long t = date.getTimeInMillis();         Date issuedAt=new Date(t);         Date expiresAt = new Date(t + (60 * 60000)); 

        try {        com.auth0.jwt.algorithms.Algorithm  algorithm = com.auth0.jwt.algorithms.Algorithm.HMAC256(Secret);         jwt_token = com.auth0.jwt.JWT.create().withSubject("user1").withIssuer(Key).withIssuedAt(issuedAt).withExpiresAt(expiresAt).withClaim("isAnonymous", true).sign(algorithm); 

        }  

catch (java.io.UnsupportedEncodingException e) {   token = "error";   oLog.error("Generate JWT : "+ e.getMessage()); } catch (Exception e) {   token = "error";   oLog.error("Generate JWT for : "+ e.getMessage()); }

return (jwt_token);
