When requesting and attempting to validate, the program prints "In the constraint if else" and then an error about lack of class pops up in the log!

In the internet, I found information about the need to have a Jersey-Common dependency! After that I downloaded from the Maven repository, but I get the same error!

  1. What is this class for?

  2. What dependency is responsible for this class?

    java.lang.RuntimeException: java.lang.ClassNotFoundException: org.glassfish.jer..internal.RuntimeDelegateImpl at javax.ws.rs. .getInstance (RuntimeDelegate.java:120)

From the logs, it is clear that there is a call to findDelegate () and then an error occurs ..

What could be the reasons for not finding this class?

public class ClientDataValidation { public Response validator(User user){ ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory(); Validator validator = validatorFactory.getValidator(); Set<ConstraintViolation<User>> constraints = validator.validate(user); if(!(constraints.isEmpty())){ System.out.print("In the constraint if else"); String [] errors = new String[constraints.size()]; int constraintCounter = 0; for (ConstraintViolation<User> constraint:constraints) { String errorMessage = constraint.getMessage(); errors[constraintCounter] = errorMessage; constraintCounter++; } constraintCounter = 0; Response.ResponseBuilder responseBuilder = Response.status(Response.Status.NOT_ACCEPTABLE).entity(errors); Response resposne = responseBuilder.build(); errors = null; return resposne; } return Response.ok().build(); } } <dependencies> <dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.5.5</version> </dependency> <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20160810</version> </dependency> <dependency> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> <version>1.1.0.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.2.4.Final</version> </dependency> <dependency> <groupId>javax.el</groupId> <artifactId>javax.el-api</artifactId> <version>2.2.4</version> </dependency> <dependency> <groupId>org.glassfish.web</groupId> <artifactId>javax.el</artifactId> <version>2.2.4</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.1.3.Final</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.3.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> </dependency> <dependency> <groupId>javax.ws.rs</groupId> <artifactId>javax.ws.rs-api</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-common</artifactId> <version>2.22.2</version> </dependency>

  • Is this your RESTFull? How does it unfold? Is registered in web.xml, or through Application? - Sergey
  • REST style, I use common servlets (doGet, doPost). Descriptor with annotations. It unfolds very simply, IDEA does everything itself, you need a few settings, it creates war exploded etc ... - Maks.Burkov
  • And what application server? Is there exactly jersey? - Sergey
  • I use Maven + Tomcat 8. As for dependencies, everything is there, Maven downloads all that it needs, Jersey only Resposne itself, ResponseBuilder classes through which a RuntimeDelegate instance was created, which was not at creation. I can throw off the source code of StackTrace itself .. there you can see that when I try to create an instance of RuntimeDelegate everything falls. - Maks.Burkov
  • Good afternoon. Did you manage to solve the problem somehow? now faced with similar. - Dred
