Getting error: java.lang.IllegalStateException: Either 'payload' or 'claims' must be specified. about jjwt HOT 5 CLOSED

This line:

Jwts.builder().signWith(SignatureAlgorithm.HS256, "61c5fd4007060fd9ed41fc6f2a155a3a47629b9e9b83d75d1c0d97ebb177fa83").compact();

Is not signing anything. You've got to specify a payload or a claims to sign in that line.

But that line is specifically for creating tokens. If you already have one, you don't need to do that. Just call the Jwts.parser()... line.

Thank You for information. I will try Your suggestion.

 try {
            Jwts.parser().setSigningKey(C.TOKENKEY).parse(JWTToken);
        } catch (SignatureException e) {
            //don't trust the JWT!
        }

*Returns me SignatureException: * JWT signature does not match locally computed signature. JWT validity cannot be asserted and should not be trusted.

What does it mean? And what I'm doing wrong?

use .parseClaimsJws instead of .parse
