Jackson Error : java.lang.NoSuchMethodError: `com.fasterxml.jackson.databind.JsonNode.asText(Ljava/lang/String;)Ljava/lang/String`

Question

I tried to validate a JWT authentication token,

JWTVerifier verifier = JWT.require(Algorithm.HMAC256("secret")).withIssuer("siat").build();
String token=httpRequest.getParameter("token");
DecodedJWT decodedJWT = verifier.verify(token);

following is exception stack trace:

java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.JsonNode.asText(Ljava/lang/String;)Ljava/lang/String;

Which version of java-jwt are you using? – Valerio Emanuele Aug 09 '17 at 08:23 — Valerio Emanuele, Aug 09 '17 at 08:23
Please add your `pom.xml` to the question. – unwichtich Aug 09 '17 at 11:47 — unwichtich, Aug 09 '17 at 11:47

Check your dependency graph whether it is pulling the correct version of Jackson-databind jar

The method it complains is available in version 2.4.0 onwards of jackson-databind.jar

If somehow you have the older version of jar in your classpath then it wouldn't serve the needed method.

Thank you for your answer. The problem was a conflict between the dependency in my POM file and the GlassFish modules. – CHHIBI AMOR Aug 09 '17 at 14:13

Glassfish dependency was my problem too: glassfish-embedded-all. – tinocoam Apr 01 '18 at 18:33

If you check the java-jwt dependencies in any maven repository, for example in MVN Repository you'll se between the compile dependencies the required version of jackson-databind (that is the one throwing the java.lang.NoSuchMethodError exception).

In your case, for java-jwt 3.1.0 version you must have jackson-databind version 2.8.4 or the new one 2.9.0.
