Generate swagger.json

Question

I have a java project (tomcat webapp) with some REST Api. I want to generate swagger documentation for them. I started from this tutorial (github). I don't have maven we use an ant task. I included swagger-annotations-1.5.0.jar and all jar that cames with swagger-jaxrs JAR 1.5.0 version( I can include a complete list if it is useful) I've annotated some method and I have a configuration class like this:

@ApplicationPath("/api")
public class Configurator extends Application {
public Configurator() {
    init();
}
private void init() {
    BeanConfig beanConfig = new BeanConfig();
    beanConfig.setVersion("1.0.0");
    beanConfig.setSchemes(new String[]{"http"});
    beanConfig.setHost("myserver.it:8080");
    beanConfig.setBasePath("/swagger-demo/api");
    beanConfig.setResourcePackage("myserver.rest");
    beanConfig.setTitle("RESTEasy, Swagger and Swagger UI Example");
    beanConfig.setScan(true);
}

}

when I deploy it agains tomcat 9 I can see this log in localhost.log file

If I try to reach http://myserver.it:8080/swagger-demo/api/ this give me 404 error.

I read this post about this error (here) but I really can't say what's wrong. I'm strugglin. Any hints would be appreciated

Answer 1

I answer to myself since I finally find a solution. Problem was inconsistency with libraries. I solved using this site Jar download, that gives me all the dependencies. Then I compare some libraries that I already jave in my project and in caso of conflict I choose the newest one.
